    Full Text Available Yeasts belonging to the genus Dekkera/Brettanomyces, especially the species Dekkera bruxellensis, have long been associated with the production of volatile phenols responsible for off-flavour in wines. According to recent reports, the species Pichia guilliermondii could also produce these compounds at the initial stages of fermentation. Based on the abundance of P. guilliermondii in Patagonian winemaking, we decided to study the relevance of indigenous isolates belonging to this species as wine spoilage yeast. Twenty-three indigenous isolates obtained from grape surfaces and red wine musts were analyzed in their capacity to produce volatile phenols on grape must. The relationship between molecular Random Amplified Polymorphic DNA (RAPD and physiological (killer biotype patterns detected in indigenous populations of P. guilliermondii and volatile phenol production was also evaluated. Different production levels of 4-ethylphenol, 4-vinylguaiacol and 4-ethylguaiacol were detected among the isolates; however, the values were always lower than those produced by the D. bruxellensis reference strain in the same conditions. High levels of 4-vinylphenol were detected among P. guilliermondii indigenous isolates. The combined use of RAPD and killer biotype allowed us to identify the isolates producing the highest volatile phenol levels.Las levaduras del género Dekkera/Brettanomyces, sobre todo la especie Dekkera bruxellensis, siempre han sido asociadas con la producción de fenoles volátiles responsables de aromas desagradables en los vinos. Recientemente, se ha demostrado que la especie Pichia guilliermondii también es capaz de producir estos compuestos, particularmente durante las etapas iniciales de la fermentación. Dada la abundancia de P. guilliermondii en las bodegas de la Patagonia, se decidió evaluar la importancia de algunos aislamientos indígenas de esta especie como levaduras alterantes de vinos regionales. Se evaluó la capacidad de

    Meyerozyma guilliermondii (anamorph Candida guilliermondii) and Meyerozyma caribbica (anamorph Candida fermentati) are closely related species of the genetically heterogenous M. guilliermondii complex. Conventional phenotypic methods frequently misidentify the species within this complex and also with other species of the Saccharomycotina CTG clade. Even the long-established sequencing of large subunit (LSU) rRNA gene remains ambiguous. We also faced similar problem during identification of yeast isolates of M. guilliermondii complex from indigenous bamboo shoot fermentation in North East India. There is a need for development of reliable and accurate identification methods for these closely related species because of their increasing importance as emerging infectious yeasts and associated biotechnological attributes. We targeted the highly variable internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2) and identified seven restriction enzymes through in silico analysis for differentiating M. guilliermondii from M. caribbica. Fifty five isolates of M. guilliermondii complex which could not be delineated into species-specific taxonomic ranks by API 20 C AUX and LSU rRNA gene D1/D2 sequencing were subjected to ITS-restriction fragment length polymorphism (ITS-RFLP) analysis. TaqI ITS-RFLP distinctly differentiated the isolates into M. guilliermondii (47 isolates) and M. caribbica (08 isolates) with reproducible species-specific patterns similar to the in silico prediction. The reliability of this method was validated by ITS1-5.8S-ITS2 sequencing, mitochondrial DNA RFLP and electrophoretic karyotyping. We herein described a reliable ITS-RFLP method for distinct differentiation of frequently misidentified M. guilliermondii from M. caribbica. Even though in silico analysis differentiated other closely related species of M. guilliermondii complex from the above two species, it is yet to be confirmed by in vitro analysis using reference strains. This method can be used

    In this study, 34 yeast isolates were obtained from koji and moromi samples of Thai soy sauce fermentation. However, the most interesting yeast strain was isolated from the enriched 2 month-old (M2) moromi sample and identified as Meyerozyma (Pichia) guilliermondii EM2Y61. This strain is a salt-tolerant yeast that could tolerate up to 20% (w/v) NaCl and produce extracellular and cell-bound glutaminases. Interestingly, its glutaminases were more active in 18% (w/v) NaCl which is a salt concentration in moromi. The extracellular glutaminase's activity was found to be much higher than that of cell-bound glutaminase. The highest specific activity and stability of the extracellular glutaminase were found in 18% (w/v) NaCl at pH4.5 and 37°C. A challenge test by adding partially-purified extracellular glutaminase from M. guilliermondii EM2Y61 into 1 month-old (M1) moromi sample showed an increased conversion of L-glutamine to L-glutamic acid. This is the first report of glutaminase producing M. guilliermondii isolated from the moromi of Thai soy sauce fermentation. The results suggested the potential application of M. guilliermondii EM2Y61 as starter yeast culture to increase l-glutamic acid during soy sauce fermentation. Copyright © 2014 Elsevier B.V.

    Full Text Available Candida guilliermondii is one of the components of human microbiota. This yeast has been infrequently associated with human infections, which may be related to its low pathogenicity. The aim of this study was to provide clinical and epidemiological data for patients infected with C. guilliermondii at Santa Casa Complexo Hospitalar, Brazil. From October 1997 to October 2003, C. guilliermondii was isolated from clinical samples from 11 patients. Three patients were excluded because the isolation of the yeast represented colonisation. Specimens from the eight patients included in the study corresponded to blood (n = 5, ascitis fluid (n = 2, and oesophagus biopsy (n = 1. Three patients (37.5% had major immunosuppressed conditions, including solid organ transplantation, AIDS, and leukaemia. Previous use of antibiotics occurred in 87.5%. Main invasive medical procedures were central venous catheter (50.0%, abdominal surgery (25.0%, and peritoneal dialysis (50.0%. No susceptibility data was obtained. Although risk factors for candidaemia were similar amongst patients infected by with C. guilliermondii or other Candida species, mortality associated with C. guilliermondii was significantly lower.Candida guilliermondii é um dos componentes da microbiota humana e infecções associadas com esta levedura têm sido incomuns, o que pode ser atribuído a sua baixa patogenicidade.

    The headwaters of the Amazon Basin harbor most of the world's last indigenous peoples who have limited contact with encroaching colonists. Knowledge of the geographic distribution of these isolated groups is essential to assist with the development of immediate protections for vulnerable indigenous settlements. We used remote sensing to document the locations of 28 isolated villages within the four Brazilian states of Acre, Amazonas, Roraima, and Rondônia. The sites were confirmed during previous over-flights and by image evidence of thatched-roof houses; they are estimated to host over 1,700 individuals. Locational data were used to train maximum entropy models that identified landscape and anthropogenic features associated with the occurrence of isolated indigenous villages, including elevation, proximity to streams of five different orders, proximity to roads and settlements, proximity to recent deforestation, and vegetation cover type. Isolated villages were identified at mid elevations, within 20 km of the tops of watersheds and at greater distances from existing roads and trails. We further used model results, combined with boundaries of the existing indigenous territory system that is designed to protect indigenous lands, to assess the efficacy of the existing protected area network for isolated peoples. Results indicate that existing indigenous territories encompass all of the villages we identified, and 50% of the areas with high predicted probabilities of isolated village occurrence. Our results are intended to help inform policies that can mitigate against future external threats to isolated peoples.

    One osmotolerant strain from among 44 yeast isolates was selected based on its growth abilities in media containing high concentrations of sucrose. This selected strain, named SKENNY, was identified as Meyerozyma guilliermondii by sequencing the internal transcribed spacer regions and partial D1/D2 large-subunit domains of the 26S ribosomal RNA. SK-ENNY was utilized to produce high-fructose glucose syrup (HFGS) from sucrose-containing biomass. Conversion rates to HFGS from 310-610 g/l of pure sucrose and from 75-310 g/l of sugar beet molasses were 73.5-94.1% and 76.2-91.1%, respectively. In the syrups produced, fructose yields were 89.4-100% and 96.5-100% and glucose yields were 57.6-82.5% and 55.3-79.5% of the theoretical values for pure sucrose and molasses sugars, respectively. This is the first report of employing M. guilliermondii for production of HFGS from sucrose-containing biomass.

    Yeast isolates from commercial red wines were characterized with regards to tolerances to molecular SO2, ethanol, and temperature as well as synthesis of 4-ethyl-phenol/4-ethyl-guaiacol in grape juice or wine. Based on rDNA sequencing, nine of the 11 isolates belonged to Dekkera bruxellensis (B1a......, B1b, B2a, E1, F1a, F3, I1a, N2, and P2) while the other two were Candida pararugosa (Q2) and Pichia guilliermondii (Q3). Strains B1b, Q2, and Q3 were much more resistant to molecular SO2 in comparison to the other strains of Dekkera. These strains were inoculated (103-104 cfu/ml) along with lower...... populations of Saccharomyces (red grape juice and red wine incubated at two temperatures, 15 C and 21 C. Although Saccharomyces quickly dominated fermentations in grape juice, B1b and Q2 grew and eventually reached populations >105 cfu/ml. In wine, Q3 never entered logarithmic growth...

    Full Text Available Abstract In the present work we isolated and identified various indigenous Saccharomyces cerevisiae strains and screened them for the selected oenological properties. These S. cerevisiae strains were isolated from berries and spontaneously fermented musts. The grape berries (Sauvignon blanc and Pinot noir were grown under the integrated and organic mode of farming in the South Moravia (Czech Republic wine region. Modern genotyping techniques such as PCR-fingerprinting and interdelta PCR typing were employed to differentiate among indigenous S. cerevisiae strains. This combination of the methods provides a rapid and relatively simple approach for identification of yeast of S. cerevisiae at strain level. In total, 120 isolates were identified and grouped by molecular approaches and 45 of the representative strains were tested for selected important oenological properties including ethanol, sulfur dioxide and osmotic stress tolerance, intensity of flocculation and desirable enzymatic activities. Their ability to produce and utilize acetic/malic acid was examined as well; in addition, H2S production as an undesirable property was screened. The oenological characteristics of indigenous isolates were compared to a commercially available S. cerevisiae BS6 strain, which is commonly used as the starter culture. Finally, some indigenous strains coming from organically treated grape berries were chosen for their promising oenological properties and these strains will be used as the starter culture, because application of a selected indigenous S. cerevisiae strain can enhance the regional character of the wines.

  11. Are Isolated Indigenous Populations Headed toward Extinction?

    Robert S Walker

    Full Text Available At least 50 indigenous groups spread across lowland South America remain isolated and have only intermittent and mostly hostile interactions with the outside world. Except in emergency situations, the current policy of governments in Brazil, Colombia, and Peru towards isolated tribes is a "leave them alone" strategy, in which isolated groups are left uncontacted. However, these no-contact policies are based on the assumption that isolated populations are healthy and capable of persisting in the face of mounting external threats, and that they can maintain population viability in the long-term. Here, we test this assumption by tracking the sizes and movements of cleared horticultural areas made by 8 isolated groups over the last 10-14 years. We used deforestation data derived from remote sensing Landsat satellite sensors to identify clearings, and those were then validated and assessed with high-resolution imagery. We found only a single example of a relatively large and growing population (c. 50 cleared ha and 400 people, whereas all of the other 7 groups exhibited much smaller villages and gardens with no sizable growth through time. These results indicated that the smaller groups are critically endangered, and it prompts an urgent re-thinking of policies toward isolated populations, including plans for well-organized contacts that may help save lives and rescue isolated indigenous populations from imminent extinction.

  13. Fermentation of hexoses and pentoses from hydrolyzed soybean hull into ethanol and xylitol by Candida guilliermondii BL 13

    Directory of Open Access Journals (Sweden)

    F. da Cunha-Pereira

    Full Text Available Abstract This work investigated the ability of a recently isolated strain of Candida guilliermondii to convert hexoses and pentoses obtained from acid-enzymatic soybean hull hydrolysates into ethanol and, in smaller amounts, into xylitol. Operational conditions and media formulation were optimized concerning ethanol production using experimental designs (Plackett-Burman and Central Composite Design. Results showed that C. guilliermondii BL 13 was capable of growing in non-supplemented, non-detoxified biomass hydrolysates, and the best culture conditions were determined to be 28 °C, pH 5.0, and 109 CFU mL-1 of inoculum size. Ethanol productivity reached 1.4 g L-1 h-1, and maximal yields of 0.41 g g-1 were obtained, representing 80.4 % of the expected theoretical yields, whereas small amounts of xylitol were also produced. These results suggest that C. guilliermondii BL13 is a potentially useful yeast strain to be applied in second-generation ethanol production from lignocellulosic biomass based on its natural capacity to metabolize C-5 and C-6 sugars.

    Currently, echinocandins are first-line drugs for treatment of invasive candidiasis. However, data on how serum influences killing activity of echinocandins against uncommon Candida species are limited. Therefore, the killing activity of micafungin in RPMI-1640 and in 50% serum was compared against Candida guilliermondii, Candida lusitaniae, and Candida kefyr. Minimum inhibitory concentration (MIC) ranges in RPMI-1640 were 0.5-1, 0.12-0.25, and 0.06-0.12 mg/L, respectively. In 50% serum, MICs increased 32- to 256-fold. In RPMI-1640 ≥ 0.25, ≥4, and 32 mg/L micafungin was fungicidal against all four C. kefyr (≤4.04 hours), two of three C. lusitaniae (≤16.10 hours), and two of three C. guilliermondii (≤12.30 hours), respectively. In 50% serum, all three species grew at ≤4 mg/L. Micafungin at 16-32 mg/L was fungicidal against all C. kefyr isolates (≤3.03 hours) and at 32 mg/L was fungistatic against one of three C. lusitaniae isolates. Two C. lusitaniae isolates and all three C. guilliermondii grew at all tested concentrations. Adding human serum to susceptibility test media drew attention to loss of fungicidal or fungistatic activity of micafungin in the presence of serum proteins, which is not predicted by MICs in case of C. kefyr and C. lusitaniae in RPMI-1640. Our results strongly suggest that micafungin and probably other echinocandins should be used with caution against rare Candida species.

    3-Hydroxypropionic acid (3-HP) is an important platform chemical in organic synthesis. Traditionally, 3-HP was produced by chemical methods and fermentation process. In this work, a novel enzymatic method was developed for green synthesis of 3-HP. A yeast strain harboring nitrile-hydrolyzing enzyme was newly isolated from environmental samples using 3-hydroxypropionitrile (3-HPN) as the sole nitrogen source. It was identified to be Meyerozyma guilliermondii CGMCC12935 by sequencing of the 18S ribosomal DNA and internal transcribed spacer, together with analysis of the morphology characteristics. The catalytic properties of M. guilliermondii CGMCC12935 resting cells were determined, and the optimum activity was achieved at 55 °C and pH 7.5. The enzyme showed broad substrate specificity towards nitriles, especially 3-HPN, aminoacetonitrile and 3-cyanopyridine. The presence of Ag + , Pb 2+ and excess substrate inhibited the enzyme activity, whereas 5% (v/v) ethyl acetate had a positive effect on the enzyme activity. M. guilliermondii CGMCC12935 resting cells by addition of 3% glucose could thoroughly hydrolyze 500 mM 3-HPN into 3-HP within 100 h and the maximal accumulative production of 3-HP reached 216.33 mM, which was over twofolds than the control group with no additional glucose. And this work would lay the foundation for biological production of 3-HP in industry.

    The vast forests on the border between Brazil and Peru harbour a number of indigenous groups that have limited contact with the outside world. Accurate estimates of population sizes and village areas are essential to begin assessing the immediate conservation needs of such isolated groups. In contrast to overflights and encounters on the ground, remote sensing with satellite imagery offers a safe, inexpensive, non-invasive and systematic approach to provide demographic and land-use information for isolated peoples. Satellite imagery can also be used to understand the growth of isolated villages over time. There are five isolated villages in the headwaters of the Envira River confirmed by overflights that are visible with recent satellite imagery further confirming their locations and allowing measurement of their cleared gardens, village areas and thatch roofed houses. These isolated villages appear to have population densities that are an order of magnitude higher than averages for other Brazilian indigenous villages. Here, we report on initial results of a remote surveillance programme designed to monitor movements and assess the demographic health of isolated peoples as a means to better mitigate against external threats to their long-term survival.

    A Research on the role of indigenous bacterial isolates for bio-remediation agent of the uranium contaminated in the aquatic environment has been conducted. The objective of the research is to study the role of Pseudomonas sp and Bacillus sp. have been isolated from low level uranium waste for bioremediation agent in their environment, such as the determination of efficiency of the uranium binding compared by the non indigenous bacterial, location of these binding and the influences of added acethyl acid stimulant. The uranium reduction studied was measured by weighting bacterial biomass and uranium concentration was measured by spectrophotometer. The acethyl acid stimulant addition has been done with the variation of concentration and volume. The efficiency of the uranium reduction by indigenous bacterial isolate such as Pseudomonas sp were 84.99 % and Bacillus sp were 52.70 %, so the reduction efficiency by non indigenous bacterial such as Pseudomonas aerogenes were 78.47 % and Bacillus subtilis were 45.22 % for 54 hours incubation time. The result of this research can be concluded that Pseudomonas sp and Bacillus sp. Indigenous bacterial have been isolates from the liquid uranium waste can contributed in bioremediation agent for uranium radionuclide in the environment for 60 ppm concentration with reduction efficiency 52.70 %-84.99 %, that is higher non indigenous bacterial for 54 hours incubation time, the stimulant addition of acethyl acid, the efficiency can be increased up to 99.8 %.

  19. Disruption of Protein Mannosylation Affects Candida guilliermondii Cell Wall, Immune Sensing, and Virulence

    Directory of Open Access Journals (Sweden)

    María J. Navarro-Arias

    2016-12-01

    Full Text Available The fungal cell wall contains glycoproteins that interact with the host immune system. In the prominent pathogenic yeast Candida albicans, Pmr1 acts as a Golgi-resident ion pump that provides cofactors to mannosyltransferases, regulating the synthesis of mannans attached to glycoproteins. To gain insight into a putative conservation of such a crucial process within opportunistic yeasts, we were particularly interested in studying the role of the PMR1 homolog in a low-virulent species that rarely causes candidiasis, Candida guilliermondii. We disrupted C. guilliermondii PMR1 and found that loss of Pmr1 affected cell growth and morphology, biofilm formation, susceptibility to cell wall perturbing agents, mannan levels, and the wall composition and organization. Despite there was a significant increment in the amount of β1,3-glucan exposed at the wall surface, this positively influenced only the ability of the mutant to stimulate IL-10 production by human monocytes, suggesting that recognition of both mannan and β1,3-glucan, is required to stimulate strong levels of pro-inflammatory cytokines. Accordingly, our results indicate C. guilliermondii sensing by monocytes was critically dependent on the recognition of N-linked mannans and β1,3-glucan, as reported in other Candida species. In addition, chemical remotion of cell wall O-linked mannans was found to positively influence the recognition of C. guilliermondii by human monocytes, suggesting that O-linked mannans mask other cell wall components from immune cells. This observation contrasts with that reported in C. albicans. Finally, mice infected with C. guilliermondii pmr1 null mutant cells had significantly lower fungal burdens compared to animals challenged with the parental strain. Accordingly, the null mutant showed inability to kill larvae in the Galleria mellonella infection model. This study thus demonstrates that mannans are relevant for the C. guilliermondii-host interaction, with

  1. Primary Candida guilliermondii Infection of the Knee in a Patient without Predisposing Factors

    2012-01-01

    Full Text Available Isolated primary candidal infection of joint is extremely rare, with only a few reported cases. It occurs as a result of accidental implantations of fungus during traumatic procedures, such as surgery, and is usually reported in patients with predisposing factors such as immunosuppression, malignancy, and drug abuse. If left untreated, irreversible deformity and pain with severe osteoarticular destruction occur. Thus, early diagnosis and treatment are important. This paper presents a case of 72-year-old man with primary C. guilliermondii infection of knee joint without predisposing factors and previous traumatic procedures, who was misdiagnosed with advanced degenerative osteoarthritis. Our case is the second case of primary C. guilliermondii arthritis of knee to be reported in the English-language literature and the first to be successfully treated with total knee arthroplasty following IV amphotericin B and oral fluconazole. Primary candidal infection of joint is generally asymptomatic or involves only mild pain and swelling in the affected knee. Thus, although the majority of knee joint infections are of a pyogenic or tuberculous origin, if a patient complains of mild pain and swelling in the knee and has mild signs of infection, the possibility of fungal infection should be considered.

  2. Functional and probiotic attributes of an indigenous isolate of Lactobacillus plantarum.

    Directory of Open Access Journals (Sweden)

    Jai K Kaushik

    Full Text Available BACKGROUND: Probiotic microorganisms favorably alter the intestinal microflora balance, promote intestinal integrity and mobility, inhibit the growth of harmful bacteria and increase resistance to infection. Probiotics are increasingly used in nutraceuticals, functional foods or in microbial interference treatment. However, the effectiveness of probiotic organism is considered to be population-specific due to variation in gut microflora, food habits and specific host-microbial interactions. Most of the probiotic strains available in the market are of western or European origin, and a strong need for exploring new indigenous probiotic organisms is felt. METHODS AND FINDINGS: An indigenous isolate Lp9 identified as Lactobacillus plantarum by molecular-typing methods was studied extensively for its functional and probiotic attributes, viz., acid and bile salt tolerance, cell surface hydrophobicity, autoaggregation and Caco-2 cell-binding as well as antibacterial and antioxidative activities. Lp9 isolate could survive 2 h incubation at pH 1.5-2.0 and toxicity of 1.5-2.0% oxgall bile. Lp9 could deconjugate major bile salts like glycocholate and deoxytaurocholate, indicating its potential to cause hypocholesterolemia. The isolate exhibited cell-surface hydrophobicity of approximately 37% and autoaggregation of approximately 31%. Presence of putative probiotic marker genes like mucus-binding protein (mub, fibronectin-binding protein (fbp and bile salt hydrolase (bsh were confirmed by PCR. Presence of these genes suggested the possibility of specific interaction and colonization potential of Lp9 isolate in the gut, which was also suggested by a good adhesion ratio of 7.4+/-1.3% with Caco-2 cell line. The isolate demonstrated higher free radical scavenging activity than standard probiotics L. johnsonii LA1 and L. acidophilus LA7. Lp9 also exhibited antibacterial activity against E. coli, L. monocytogenes, S. typhi, S. aureus and B. cereus. CONCLUSION

    Full Text Available This article is about isolation, contact, and relations between two Amazonian indigenous peoples: the Matis and the Korubo. Both groups, of the Panoan linguistic family, live in the Vale do Javari Indigenous Land, in the state of Amazonas, Brazil. The Matis were contacted by the Funai (the Brazilian agency for indigenous affairs in 1976, and they worked as intermediaries helping the Brazilian government to make contact with the Korubo in 1996. Since then, the Matis have been the main translators and mediators between the Korubo and the rest of the world (indigenous and non-indigenous. Based on my investigation, I propose to classify “isolation” in different ways and to relate the Matis’ own narratives about their contact with their neighbors the Korubo in order to approximate a native conception of what “isolation” and “isolated peoples” mean—if they mean anything at all.

    Indigenous cellulolytic bacterial isolates having high activities in degrading carboxymethyl cellulose (CMC) were isolated from local environments. Identification of these isolates were performed by molecular techniques. By using polymerase chain reaction (PCR) techniques, PCR products encoding cellulase gene were amplified from the total genomic DNAs. Purified PCR product was successfully cloned and expressed in Escherichia coli host system. The complete nucleotide sequences of the cellulase genes determined. The analysis of amino acid sequences deduced from the genes indicated that the cloned DNA fragments show high homology to those of endoglucanase genes of family GH5. All cloned genes consist of an N-terminal signal peptide, a catalytic domain of family 5 glycosyl hydrolase and a cellulose-binding domain of family III. (Author)

    Full Text Available Yeasts of the genus Candida are of clinical importance and also have many industrial applications, mainly in the food industry. The yeast Candida guilliermondii FTI 20037 has been extensively studied in order to establish a biotechnological process for the production of xylitol. The goal of this study was to verify the taxonomic classification of this strain based on the analysis of rDNA sequences and the xyl1 gene. DNA fragments from these sequences were amplified by PCR and BLAST analysis revealed strong identity with the corresponding sequences from Candida tropicalis. Based on these results, we propose that C. guilliermondii FTI 20037 must be reclassified as C. tropicalis.As leveduras do gênero Candida possuem tanto importância clínica como diversas aplicações industriais, principalmente na indústria de alimentos. A levedura Candida guilliermondii FTI 20037 tem sido exaustivamente estudada pois pretende-se utilizá-la no estabelecimento de um processo biotecnológico para a produção de xilitol. O objetivo deste trabalho foi verificar a classificação taxonômica desta levedura por análise de sequências do rDNA e do gene xyl1. Fragmentos correspondentes a estas regiões foram amplificados por PCR e a análise destas sequências por BLAST revelou alta identidade com sequências correspondentes de Candida tropicalis. Estes resultados nos levam a propor que C. guilliermondii FTI 20037 deva ser reclassificada como C. tropicalis.

    A preliminary study was carried out with the aim to obtain strong cellulolytic bacteria by ionizing radiation using a 60 Co source. An indigenous cellulolytic Bacillus sp. NMBCC 10023 originally isolated from soil origin was used in the study. The harvested bacterial pellets from overnight growth cultures were exposed to gamma-irradiation with doses ranging from 1 kGy to 40 kGy. The numbers of surviving bacteria on agar plate decreased as the gamma irradiation dose increased. No isolates were recovered after exposure to doses greater than 10 kGy. Based on the cell count using plate count method, the 90 % lethal dose (LD90) of gamma radiation of Bacillus sp. NMBCC 10023 was between 2-4 kGy. (author)

    Full Text Available Extracellular lipases from the endophytic yeast Candida guilliermondii isolated from castor leaves (Ricinus communis L. were produced using low-cost raw materials such as agro-industrial residues and applying them in the esterification of oleic acid for evaluating their potential use in biodiesel production. After partial purification using ammonium sulfate, the enzyme was characterized and presented higher activity (26.8 ± 1.5 U mL-1 in the presence of 5 mmol L-1 NaCl at 30 ºC and pH 6.5. The production through submerged fermentation was formerly performed in 150 mL erlenmeyer flasks and, once the enzyme production was verified, assays in a 14 L bioreactor were conducted, obtaining 18 ± 1.4 U mL-1. The produced enzyme was applied in the oleic acid esterification under different solvents: hexane, cyclohexane or cyclohexanone and different acid:alcohol molar ratios. Higher ester conversion rate (81% was obtained using hexane and the molar ratio of 1:9 was the best conditions using methanol. The results suggest the potential for development of endophytic yeast in the production of biocatalyst through submerged fermentation using agroindustrial residues as culture medium.

    Non-Saccharomyces yeasts include different species which comprise an ecologically and biochemically diverse group capable of altering fermentation dynamics and wine composition and flavour. In this study, single- and mixed-culture of Hanseniaspora guilliermondii and Saccharomyces cerevisiae were used to ferment natural grape-juice, under two nitrogen regimes. In single-culture the strain H. guilliermondii failed to complete total sugar breakdown even though the nitrogen available has not been a limiting factor of its growth or fermentative activity. In mixed-culture, that strain negatively interfered with the growth and fermentative performance of S. cerevisiae, resulting in lower fermentation rate and longer fermentation length, irrespective of the initial nitrogen concentration. The impact of co-inoculation on the volatile compounds profile was more evident in the wines obtained from DAP-supplemented musts, characterised by increased levels of ethyl and acetate esters, associated with fruity and floral character of wines. Moreover, the levels of fatty acids and sulphur compounds which are responsible for unpleasant odours that depreciate wine sensory quality were significantly lower. Accordingly, data obtained suggests that the strain H. guilliermondii has potential to be used as adjunct of S. cerevisiae in wine industry, although possible interactions with S. cerevisiae still need to be elucidated.

    Full Text Available Xylitol was produced by Candida guilliermondii from charcoal-treated and untreated rice straw hemicellulosic hydrolysate with or without nutrients (ammonium sulphate, calcium chloride, rice bran extract. Both, xylitol yield and volumetric productivity decreased significantly when the nutrients were added to treated and untreated hydrolysates. In the treated hydrolysate, the efficiency of xylose conversion to xylitol was 79% when the nutrients were omitted. The results demonstrated that rice straw hemicellulosic hydrolysate treated with activated charcoal was a cheap source of xylose and other nutrients for xylitol production by C. guilliermondii. The non-necessity of adding nutrients to the hydrolysate media would be very advantageous since the process becomes less costly.Este trabalho avaliou a produção de xilitol pela levedura Candida guilliermondii, a partir de hidrolisado hemicelulósico de palha de arroz não tratado e tratado com carvão ativo, ambos suplementados ou não com nutrientes (sulfato de amônio, cloreto de cálcio e extrato de farelo de arroz. Os resultados mostraram que tanto o rendimento como a produtividade volumétrica em xilitol diminuíram quando os nutrientes foram adicionados em ambos hidrolisados, tratado e não tratado. Em hidrolisado tratado, a eficiência de conversão de xilose em xilitol foi de 79% quando em ausência de nutrientes. Estes resultados mostram que o hidrolisado hemicelulósico de palha de arroz tratado com carvão ativo é uma fonte barata de xilose e outros nutrientes, para a produção de xilitol por Candida guilliermondii. A não necessidade de adicionar nutrientes ao meio a base de hidrolisado é muito vantajosa, uma vez que o processo se torna mais econômico.

    Hybrid histidine kinases (HHKs) progressively emerge as prominent sensing proteins in the fungal kingdom and as ideal targets for future therapeutics. The group X HHK is of major interest, since it was demonstrated to play an important role in stress adaptation, host-pathogen interactions and virulence in some yeast and mold models, and particularly Chk1, that corresponds to the sole group X HHK in Candida albicans. In the present work, we investigated the role of Chk1 in the low-virulence species Candida guilliermondii, in order to gain insight into putative conservation of the role of group X HHK in opportunistic yeasts. We demonstrated that disruption of the corresponding gene CHK1 does not influence growth, stress tolerance, drug susceptibility, protein glycosylation or cell wall composition in C. guilliermondii. In addition, we showed that loss of CHK1 does not affect C. guilliermondii ability to interact with macrophages and to stimulate cytokine production by human peripheral blood mononuclear cells. Finally, the C. guilliermondii chk1 null mutant was found to be as virulent as the wild-type strain in the experimental model Galleria mellonella. Taken together, our results demonstrate that group X HHK function is not conserved in Candida species. Copyright © 2017 Institut Pasteur. Published by Elsevier Masson SAS. All rights reserved.

    Setting: The Prairie provinces of Canada. Objective: To understand how Indigenous peoples with infectious pulmonary tuberculosis living in different community settings in the Prairie provinces of Canada experience respiratory isolation. Design: Using an exploratory qualitative approach, we interviewed participants living in urban centres, non-remote reserve settings and remote and isolated reserve settings. Results: Through qualitative content analysis of 48 interviews, we determined that participants experienced feelings of confinement regardless of the community setting in which they lived. Participants also experienced family and social disconnect, but the experience was more potent for the remote and isolated reserve participants, who were required to be flown out of their home communities to receive treatment, and for those urban centre and non-remote reserve participants who lacked social connections. The roles of past experiences with sanitoria and of family in providing social support are discussed. Conclusions: The conclusions of this study focus on examining isolation policies and improving the hospital isolation experience.

    Full Text Available Attachment of yeast cells or bacteria on fungal hyphae have been observed in various antagonisms between microorganisms. Physical interactions between yeast Pichia guilliermondii and postharvest fruit pathogen Penicillium expansum in culture were studied in detail using light and transmission electron microscope to give better understanding on their mode of antagonism. Both organisms were co-cultured for 24-hr on potato dextrose agar. Light microscopy observations on the co-culture showed that the yeast cells attached firmly on the fungal hyphae. This attachment was inhibited by several substances such as enzymes degrading protein (protease or trypsin, a respiration inhibitor (sodium azide, an acid (hydrochloric acid or an alkali (sodium hydroxide. Although autoclaved hyphae did not affect the attachment, but boiled enzymes and autoclaved yeast cells totally abolished the attachment. These evidences suggested that the attachment might be an active process mediated by certain protein from live yeast cells. Transmission electron micrographs on the ultrastructure of the co-culture revealed that the hyphae showed abnormalities in their structure and organelles, and a degree of obvious damage. Physical interactions observed in this study could be contributed to the mechanism of antagonism between P. guilliermondii and P. expansum.

    Full Text Available Istrian ewe’s milk cheese is an autochthonous product that is manufactured for generations on small family farms in the Croatian peninsula Istria. Traditional Istrian cheese is made from unpasteurized ewe’s milk, without the addition of starter cultures. Consequently, the specific flavour and texture of the Istrian cheese is owed to metabolic processes of indigenous microflora of which Lactobacillus species play pivotal role. Characterisation and selection of indigenous lactobacilli may result in the potential use of selected strains as starter, bioprotective or even probiotic cultures. This study focuses on potential use of Lactobacillus plantarum and Lactobacillus casei isolated from traditional Istrian cheese as starter cultures, by using methods that determine their proteolytic, lipolytic, antimicrobial and haemolytic potential, as well as their ability of acidification, autoaggregation and survival in simulated gastrointestinal conditions. Our results indicated that from 12 representative strains most revealed a low or moderate proteolytic activity as well as absence of lipolytic and haemolytic activities. From 12 strains, 5 of them showed a medium to strong acidification ability and lowered the pH of milk below 5.00 after 24 hours of incubation. Furthermore, almost all isolates exhibited antimicrobial activity against Serratia marcescens, and lowest number of isolates showed antimicrobial activity against Staphylococcus aureus and Listeria innocua. The studied Lactobacillus strains revealed high survival rate in a simulated oral cavity and duodenum conditions, while the survival ability in a simulated gastric conditions was much lower. Ability to aggregate was low for all tested strains, after 3 hours and after 5 hours of incubation.

    Opportunistic fungal infections are usually seen in immunocompromised patients. While Candida is the most prevalent agent in such infections, Aspergillus is at the second order. Primary cutaneous aspergillosis is most common in immunocompromised patients but can rarely be seen in healthy hosts as well. We report a case of posttraumatic primary cutaneous aspergillosis and Candida guilliermondii coinfection in a 70-years-old healthy man. The patient had an ulcerous lesion which developed in the site of a trauma on the middle finger of the right hand. Histopathological examination of the biopsy specimens revealed septate hyphae with dichotomous branching small circular blastospores. The cultures of the biopsy specimen yielded yellow-green colored, granular mold colonies and creamy white yeast colonies. Microscopic examination of the lactophenol cotton blue stained mold colonies indicated long conidiophores with vesicles surrounded by uniseriate phialides, compatible with Aspergillus flavus. Yeast colonies were identified as Candida guilliermondii by ID32C (BioMerieux, France) and by their microscopical morphology detected in corn meal-Tween 80 agar incubated at 25°C for 72 hours. The patient was treated properly with surgical debridement and itraconazole therapy. Since the immune system is compressed as a consequence of aging, cutaneous opportunistic fungal infections should be considered in the differential diagnosis of posttraumatic necrotic ulcers and black eschar in aged patients.

    Full Text Available Marshmallow is a host of a number of saprophytic and parasitic fungi in Serbia. The seeds of marshmallow are contaminated with fungi from different genera, especially Alternaria and Fusarium, which significantly reduced seed germination and caused seedling decay. In this study we investigate antagnonism of indigenous Bacillus sp. isolate Q3 against marshmallow mycopopulation. Bacillus sp. Q3 was isolated from maize rhizosphere, characterized by polyphasic approch and tested for plant growth promoting treats. Bacillus sp. Q3 produced antifungal metabolites with growth inhibition activity against numerous fungi in dual culture: 61.8% of Alternaria alternata, 74.8% of Myrothecium verrucaria and 33.6% of Sclerotinia sclerotiorum. That effect could be caused by different antifungal metabolites including siderophores, hydrolytic enzymes, organic acids and indole acetic acid (IAA. Suppression of natural marshmallow seed infection by Q3 isolate was observed. The seeds were immersed in different concentrations of bacterial suspension during 2h and their infections by phytopathogenic fungi were estimated. The results showed significant reduction of seed infection by Alternaria spp. The presented results indicate possible application of this isolate as promising biological agent for control of marshmallow seed pathogenic fungi.

    Candida species other than Candida albicans are increasingly recognized as causes of biofilm-associated infections. This is a comprehensive study that compared the in vitro activities of all three echinocandins against biofilms formed by different common and infrequently identified Candida isolates. We determined the activities of anidulafungin (ANID), caspofungin (CAS), and micafungin (MFG) against planktonic cells and biofilms of bloodstream isolates of C. albicans (15 strains), Candida parapsilosis (6 strains), Candida lusitaniae (16 strains), Candida guilliermondii (5 strains), and Candida krusei (12 strains) by XTT [2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide] assay. Planktonic and biofilm MICs were defined as ≥50% fungal damage. Planktonic cells of all Candida species were susceptible to the three echinocandins, with MICs of ≤1 mg/liter. By comparison, differences in the MIC profiles of biofilms in response to echinocandins existed among the Candida species. Thus, C. lusitaniae and C. guilliermondii biofilms were highly recalcitrant to all echinocandins, with MICs of ≥32 mg/liter. In contrast, the MICs of all three echinocandins for C. albicans and C. krusei biofilms were relatively low (MICs ≤ 1 mg/liter). While echinocandins exhibited generally high MICs against C. parapsilosis biofilms, MFG exhibited the lowest MICs against these isolates (4 mg/liter). A paradoxical growth effect was observed with CAS concentrations ranging from 8 to 64 mg/liter against C. albicans and C. parapsilosis biofilms but not against C. krusei, C. lusitaniae, or C. guilliermondii. While non-albicans Candida planktonic cells were susceptible to all echinocandins, there were drug- and species-specific differences in susceptibility among biofilms of the various Candida species, with C. lusitaniae and C. guilliermondii exhibiting profiles of high MICs of the three echinocandins.

    Full Text Available The Brazil-Peru border is inhabited by the second largest concentration of peoples in voluntary isolation of the world. These societies maintain a high degree of autonomy and avoid permanent contact with the surrounding societies. Since 2000, this region has been the target of policies aimed to favor the access to world markets (timber, oil, hydroelectric project, and the construction of infrastructure within the frame of the regional integration project IIRSA. This paper analyzes this situation, which threatens the survival of the isolated peoples who live in the region and has led to migratory processes of some of them from Peru into Brazil, and the reordering of the indigenous territories in this border region. These migrations often result in tense situations that can lead to conflicts between isolated and contacted groups. This calls for new strategies by the Brazilian and Peruvian organizations responsible for the protection and safeguarding of their rights, and for a greater integration between the institutions of both countries.

    Isolated pulmonary valve infective endocarditis caused by Candida is rare in chronic hemodialysis patients. The 2009 Infectious Diseases Society of America guidelines suggest the combined use of surgery and antibiotics to treat candidiasis; however, successful nonsurgical treatment of Candida endocarditis has been reported. A 63-year-old woman with end-stage kidney disease was admitted to our hospital after experiencing disorientation for 5 days. The patient was permanently bedridden because of depression, and denied active intravenous drug use. She received maintenance hemodialysis through a tunneled-cuffed catheter. An initial blood culture grew Candida guilliermondii without other bacteria. Subsequent blood cultures and tip culture of tunneled-cuffed catheter also grew C. guilliermondii, even after caspofungin replaced fluconazole. A 1.2-cm mobile mass was observed on the pulmonary valve. Surgical intervention was suggested, but the family of the patient declined because of her multiple comorbidities. The patient was discharged with a prescription of fluconazole, but she died soon after. Our patient is the first case with isolated pulmonary valve endocarditis caused by C. guilliermondii in patients with uremia. Hematologic disorders, in addition to long-term central venous catheter use, prolonged antibiotic intravenous injection, and congenital cardiac anomaly, predispose to the condition. The diagnosis "isolated" pulmonary IE is difficult, and combing surgery with antifungal antibiotics is the appropriate therapeutic management for Candida related pulmonary IE.

    Full Text Available The aim of this study was to isolate yeasts from subclinical mastitic cows and to investigate the slime production by the isolated yeasts. The material used in this study included 339 milk samples from 152 dairy cattle with subclinical mastitis. Milk was plated onto blood agar, MacConkey agar and Sabouraud dextrose agar. Forty-one samples (12.1% of total milk samples were found positive for the yeast by API 20 C AUX identification system. The isolated yeasts were classified into four genera of Candida, Trichosporon, Cryptococcus and Saccharomyces. The Candida species were following: C. krusei, C. kefyr, C. guilliermondii, C. famata, C. rugosa and C. utulis. Other yeasts were identified as Trichosporon mucoides, T. asahii, Cryptococcus laurentii, C.  neoformans and Saccharomyces cerevisiae. Slime production was tested on Congo red brain heart infusion agar and evaluated according to Congo red phenomenon. Fifteen (36.6% strains were slime factor positive: seven were C. krusei, four C. kefyr, one C. guilliermondii, one C. famata, one T. asahii, and one C. laurentii. The results of the present study indicate that yeast mastitis is significant for causing economic losses and slime production is mostly found in non-albicans Candida species. Therefore, non-albicans Candida species should be examined for slime production.

    A high throughput screening (HTS) methodology for evaluation of cellular lipid content based on Nile red fluorescence reads using black background 96-wells test plates and a plate reader equipment allowed the rapid intracellular lipid estimation of strains from a Brazilian phylloplane yeast collection. A new oleaginous yeast, Meyerozyma guilliermondii BI281A, was selected, for which the gravimetric determination of total lipids relative to dry weight was 52.38% for glucose or 34.97% for pure glycerol. The lipid production was optimized obtaining 108 mg/L of neutral lipids using pure glycerol as carbon source, and the strain proved capable of accumulating oil using raw glycerol from a biodiesel refinery. The lipid profile showed monounsaturated fatty acids (MUFA) varying between 56 or 74% in pure or raw glycerol, respectively. M. guilliermondii BI281A bears potential as a new biodiesel feedstock.

    A new ascomycetous yeast species, Candida neustonensis is proposed in this study based on four strains (SN92(T), SN47, SJ22, SJ25) isolated from sea surface microlayer in Taiwan. These four yeast strains were morphologically, physiologically and phylogenetically identical to each other. No sexual reproduction was observed on 5% malt extract agar, corn meal agar, V8 agar, McClary's acetate agar and potato-dextrose agar. Phylogenetic analysis of the sequences of the D1/D2 domain of the large subunit (LSU) rRNA gene places C. neustonensis as a member of the Pichia guilliermondii clade, it also reveals that the phylogenetically closest relatives of C. neustonensis are C. fukuyamaensis (4.4% divergence), C. xestobii (4.4% divergence) and P. guilliermondii (4.5% divergence). C. neustonensis also is clearly distinguished from other known species in the P. guilliermondii clade based on the results of physiology tests. From these comparison analyses, the following novel yeast species is proposed: Candida neustonensis sp. nov., with strain SN92(T) (= BCRC 23108(T) = JCM 14892(T) = CBS 11061(T)) as the type strain.

    Indigenous peoples across all the continents of the globe live with major gaps in health status and health outcomes associated with well-described social determinants of health, such as poverty and poor education. Indigenous peoples face additional health determinant issues associated with urbanization, isolation from traditional territories, and loss of cultural continuity. Indigenous children are particularly vulnerable as they grow up in isolation from their cultural and social roots and yet are also separated from the mainstream environment of their society. Programs to address these difficult health issues should be viewed as complex clinical interventions with health researchers, social scientists, and clinicians working together with Indigenous peoples to identify the most pressing needs and most appropriate and workable solutions that will result in effective policies and practices.

    Full Text Available Indigenous women from the Amazon regions have some of the highest rates of cervical cancer in the world. This study evaluated cervical cytology and human papillomavirus (HPV in native women that differ by lifestyle and interaction with western society. Yanomami women are isolated deep in the Amazon with a hunter/gatherer lifestyle. Macuxi and Wapishana women live in proximity to western society.To select a representative group of women from each district, random cluster sampling was used, considering each registered village as a cluster. Cervical samples were collected for cytology and HPV detection and typing by PCR amplification and next generation sequencing. The study was approved by the National IRB and by tribal leaders.664 native women were enrolled from 13 indigenous villages (76% participation rate. Yanomami women had higher rates of abnormal cytology (5.1% vs. 1.8%, p = 0.04 and prevalent HR-HPV (34.1% vs. 19.2%, p35 y of age were significantly more likely to have HR-HPV, whereas women ≤ 35 y did not significantly differ between groups. Prevalence of HPV was significantly different amongst geographically clustered Yanomami women (p<0.004. The most prevalent HPV types in the entire group were HPV31 (8.7%, HPV16 (5.9% and HPV18 (4.4%.Isolated endogenous Yanomami women were more likely to be HPV+ and rates increased with age. Study of HPV in isolated hunter-gather peoples suggests that long-term persistence is a characteristic of prehistoric humans and patterns reflecting decreased prevalence with age in western society represents recent change. These studies have implications for cervical cancer prevention and viral-host relationships.

    Full Text Available In previous studies it was shown that Pichia guilliermondii strain Z1, isolated from healthy Moroccan citrus Valencia-Late oranges, was effective against Penicillium italicum. Here the effectiveness of strain Z1 was assessed against Penicillium digitatum, the causal agent of green mould, under different temperature (5-25°C and relative humidity (RH (45-100% regimes for its reliable and largescale application in packinghouse. All main effects and interactions were significant (P80%. Its applications as a formulated product significantly reduced the incidence of infected fruit (55% and the percentage of infected wounds (47% compared to the only pathogen control treatment. However, disease control with formulated product was significantly less than that obtained with thiabendazole (30% or strain Z1 culturable cells (35%. These results highlight that strain Z1 is an effective biological control agent for control of green mould under varying environmental conditions, and control may be optimized by combining its use with other environmentally-safe post-harvest treatments or improved formulation.

    2015-10-01

    This study deals with understanding the effects of salt reduction on both the physicochemical and microbiological properties of soy sauce fermentation and also the application of indigenous yeast starters to compensate for undesirable changes occurring in salt-reduced processes. Fermentation was tested in situ at a Korean commercial soy sauce processing unit. Salt reduction resulted in higher acidity as well as lower pH and contents of residual sugar and ethanol. Moreover, undesired flavor characteristics, due to a lack of distinctive compounds, was observed. In addition, putrefactive Staphylococcus and Enterococcus spp. were present only during salt-reduced fermentation. To control these adverse effects, a single or mixed culture of two indigenous yeasts, Torulaspora delbrueckii and Pichia guilliermondii, producing high ethanol and 3-methyl-1-butanol, respectively, were tested. Overall, all types of yeast applications inhibited undesirable bacterial growth despite salt reduction. Of the starter cultures tested, the mixed culture resulted in a balance of more complex and richer flavors with an identical flavor profile pattern to that obtained from high salt soy sauce. Hence, this strategy using functional yeast cultures offers a technological option to manufacture salt-reduced soy sauce while preserving its typical sensory characteristics without affecting safety.

    To understand the isolation and classification state of actinobacterial species with valid names for Korean indigenous isolates, isolation source, regional origin, and taxonomic affiliation of the isolates were studied. At the time of this writing, the phylum Actinobacteria consisted of only one class, Actinobacteria, including five subclasses, 10 orders, 56 families, and 330 genera. Moreover, new taxa of this phylum continue to be discovered. Korean actinobacterial species with a valid name has been reported from 1995 as Tsukamurella inchonensis isolated from a clinical specimen. In 1997, Streptomyces seoulensis was validated with the isolate from the natural Korean environment. Until Feb. 2016, 256 actinobacterial species with valid names originated from Korean territory were listed on LPSN. The species were affiliated with three subclasses (Acidimicrobidae, Actinobacteridae, and Rubrobacteridae), four orders (Acidimicrobiales, Actinomycetales, Bifidobacteriales, and Solirubrobacterales), 12 suborders, 36 families, and 93 genera. Most of the species belonged to the subclass Actinobacteridae, and almost of the members of this subclass were affiliated with the order Actinomycetales. A number of novel isolates belonged to the families Nocardioidaceae, Microbacteriaceae, Intrasporangiaceae, and Streptomycetaceae as well as the genera Nocardioides, Streptomyces, and Microbacterium. Twenty-six novel genera and one novel family, Motilibacteraceae, were created first with Korean indigenous isolates. Most of the Korean indigenous actionobacterial species were isolated from natural environments such as soil, seawater, tidal flat sediment, and fresh-water. A considerable number of species were isolated from artificial resources such as fermented foods, wastewater, compost, biofilm, and water-cooling systems or clinical specimens. Korean indigenous actinobacterial species were isolated from whole territory of Korea, and especially a large number of species were from Jeju

Studies of field populationsof rhizobia open up the possibility to preserve and probably exploit some indigenous strains with hidden symbiotic or ecological potentials. The main aim of the present study is to determine genetic diversity of common bean rhizobia isolated from different field sites in central Croatia and to evaluate their symbiotic efficiency and compatibility with host plants. The isolation procedure revealed that most soil samples contained no indigenous common bean rhizobia. The results indicate that the cropping history had a significant impact on the presence of indigenous strains. Although all isolates were found to belong to species Rhizobium leguminosarum, significant genetic diversity at the strain level was determined. Application of both random amplifi cation of polymorphic DNA (RAPD and enterobacterial repetitive intergenic consensus–polymerase chain reaction (ERIC-PCR methods resulted in similar grouping of strains. Symbiotic efficiency of indigenous rhizobia as well as their compatibility with two commonly grown bean varieties were tested in field experiments. Application of indigenous rhizobial strains as inoculants resulted in significantly different values of nodulation, seed yield as well as plant nitrogen and seed protein contents. The most abundant nodulation and the highest plant nitrogen and protein contents were determined in plants inoculated with R. leguminosarum strains S17/2 and S21/6. Although, in general, the inoculation had a positive impact on seed yield, differences depending on the applied strain were not determined. The overall results show the high degree of symbiotic efficiency of the specific indigenous strain S21/6. These results indicate different

Using exogenous precursors of serotonin, it appears that the above two mechanisms involve photoactivated synthesis of serotonin. It has been postulated that the serotonin effect could take place by binding to DNA. (author)

    Full Text Available Approximately 10% of the Brazilian indigenous population lives in the state of Mato Grosso do Sul (MS, where a large number of new cases of tuberculosis (TB are reported. This study was conducted to assess TB occurrence, transmission and the utility of TB diagnosis based on the Ogawa-Kudoh (O-K culture method in this remote population. The incidence of TB was estimated by a retrospective review of the surveillance data maintained by the Notifiable Diseases Surveillance System for the study region. The TB transmission pattern among indigenous people was assessed by genotyping Mycobacterium tuberculosis isolates using the IS 6110 restriction fragment length polymorphism (RFLP technique. Of the 3,093 cases identified from 1999-2001, 610 (~20% were indigenous patients (average incidence: 377/100,000/year. The use of the O-K culture method increased the number of diagnosed cases by 34.1%. Of the genotyped isolates from 52 indigenous patients, 33 (63.5% belonged to cluster RFLP patterns, indicating recently transmitted TB. These results demonstrate high, on-going TB transmission rates among the indigenous people of MS and indicate that new efforts are needed to disrupt these current transmissions.

    The tolerance of the pentose-fermenting yeast Meyerozyma guilliermondii to the inhibitors released after the biomass hydrolysis, such as acetic acid and furfural, was surveyed. We first verified the effects of acetic acid and cell concentrations and initial pH on the growth of a M. guilliermondii strain in a semi-synthetic medium containing acetic acid as the sole carbon source. Second, the single and combined effects of furfural, acetic acid, and sugars (xylose, arabinose, and glucose) on the sugar uptake, cell growth, and ethanol production were also analysed. Growth inhibition occurred in concentrations higher than 10.5 g l -1 acetic acid and initial pH 3.5. The maximum specific growth rate (µ) was 0.023 h -1 and the saturation constant (ks) was 0.75 g l -1 acetic acid. Initial cell concentration also influenced µ. Acetic acid (initial concentration 5 g l -1 ) was co-consumed with sugars even in the presence of 20 mg l -1 furfural without inhibition to the yeast growth. The yeast grew and fermented sugars in a sugar-based medium with acetic acid and furfural in concentrations much higher than those usually found in hemicellulosic hydrolysates.

    The present communication is concerned with the effects of near-UV radiation (300-380 nm) on yeast Candida guilliermondii. It was found that certain doses of 313 nm irradiation caused inactivation of the yeast which was exhibited in a way different from the lethal action of far-UV radiation. It was also found that the cells inactivated by 313 nm are capable of recovering vitality, if incubated for some time in a non-nutrient medium. The yeast inactivated by far-UV radiation also proved to be capable of recovering, though to a lesser degree. Both 334 nm radiation and non-lethal doses at 313 nm induced the photoprotective effect against far-UV damage. The effect was exhibited if there was a certain time interval (2-4 h) between the exposures to photoprotective light and subsequent far-UV radiation. Within this time interval the extent of photoprotection was dependent on temperature. (author)

    Indigenous populations, in common with all populations, stand to benefit from the potential of genetic research to lead to improvements in diagnostic and therapeutic tools for a wide range of complex diseases. However, many Indigenous communities, especially ones that are isolated, are not included in genetic research efforts. This situation is largely a consequence of the challenges of ethically conducting genetic research in Indigenous communities and compounded by Indigenous peoples' negative past experiences with genetic issues. To examine ways of addressing these challenges, we review one investigation of a cancer cluster in remote Aboriginal communities in Arnhem Land, Australia. Our experiences demonstrate that genetic research can be both ethically and successfully conducted with Indigenous communities by respecting the authority of the community, involving community members, and including regular community review throughout the research process.

    Full Text Available Background:  The major of this study was to isolate oil-degrading bacteria from soil contaminated with petroleum and examining the removal of hydrocarbons by these bacteria. Methods: Oil-degrading colonies were purified from the samples obtained of around Ahvaz oil wells. Organic matter degradation was investigated with 1 g of crude oil in basal salt medium (BSM as sole carbon source. The growth rate was determined through total protein assay and hydrocarbon consuming was measured through organic carbon oxidation and titration by dichromate as oxidizing agent. Results: Two potential isolates named S1 and S2 strains were screened and identified as Planococcus and Pseudomonas aeruginosa. As results for S1 and S2 could degrade 80.86 and 65.6% of olive oil, 59.6 and 35.33 of crude oil, while 32 and 26.15 % of coal tar were consumed during 14 days incubation. Conclusion: The results of this investigation showed these indigenous strains high capability to biodegradation at short time and are desirable alternatives for treatment of oil pollutants.

    Full Text Available Response of Nigerian indigenous (local and broiler chickens to experimental Eimeria infections was investigated by measures of clinical signs, packed cell volume (PCV, body weights (BW, feed consumption, faecal oocyst counts (oocyst per gram, and microscopic intestinal lesions. Three-week-old chickens of each breed received single pulse infections with 2500, 5000, and 100.000 sporulated Eimeria oocysts. Infected birds were dull and passed bloody diarrhoea. OPG showed a dose related response but no significant difference between groups (P>0.05. OPG was significantly higher in local chickens (P<0.05 and varied significantly with time (P<0.05. PCV declined significantly in infected birds within breeds and groups (P<0.05; however, the decline in PCV was significantly greater in broilers (P<0.05. Both breeds had significant BW gains (P<0.05. BW gain varied between groups being significantly higher in the uninfected control broilers than in the infected broilers (P<0.05. Comparatively, broilers gained significantly more BW than their local counterparts (P<0.05. Feed intake increased significantly with time (P<0.05 in both breeds. The Eimeria isolate was pathogenic to both breeds of chicken although clinical signs and lesions were more severe in indigenous chickens suggesting the breed’s more susceptibility.

    This study investigated lytic enzyme activities in three indigenous Trichoderma strains namely, Trichoderma asperellum, Trichoderma harzianum and Trichoderma sp. Native Trichoderma strains and a virulent strain of Rhizoctonia solani isolated from infected bean plants were also included in the study. Enzyme activities were determined by measuring sugar reduction by dinitrosalicylic acid (DNS) method using suitable substrates. The antagonists were cultured in minimal salt medium with the following modifications: medium A (1 g of glucose), medium B (0.5 g of glucose + 0.5 g of deactivated R. solani mycelia), medium C (1.0 g of deactivated respective antagonist mycelium) and medium D (1 g of deactivated R. solani mycelia). T asperellum showed presence of higher amounts of chitinases, β-1, 3-glucanases and xylanases in extracellular protein extracts from medium D as compared to medium A. While, the higher activities of glucosidases and endoglucanses were shown in medium D extracts by T. harzianum. β-glucosidase activities were lower compared with other enzymes; however, activities of the extracts of medium D were significantly different. T. asperellum exhibited maximum inhibition (97.7%). On the other hand, Trichoderma sp. did not show any effect on mycelia growth of R. solani on crude extract.

    Istrian ewe’s milk cheese is an autochthonous product that is manufactured for generations on small family farms in the Croatian peninsula Istria. Traditional Istrian cheese is made from unpasteurized ewe’s milk, without the addition of starter cultures. Consequently, the specific flavour and texture of the Istrian cheese is owed to metabolic processes of indigenous microflora of which Lactobacillus species play pivotal role. Characterisation and selection of indigenous lactobacilli may resul...

  3. Effect of Furfural, Vanillin and Syringaldehyde on Candida guilliermondii Growth and Xylitol Biosynthesis

    Science.gov (United States)

    Kelly, Christine; Jones, Opal; Barnhart, Christopher; Lajoie, Curtis

    Xylitol is a five-carbon sugar alcohol with established commercial use as an alternative sweetener and can be produced from hemicellulose hydrolysate. However, there are difficulties with microbiological growth and xylitol biosynthesis on hydrolysate because of the inhibitors formed from hydrolysis of hemicellulose. This research focused on the effect of furfural, vanillin, and syringaldehyde on growth of Candida guilliermondii and xylitol accumulation from xylose in a semi-synthetic medium in microwell plate and bioreactor cultivations. All three compounds reduced specific growth rate, increased lag time, and reduced xylitol production rate. In general, increasing concentration of inhibitor increased the severity of inhibition, except in the case of 0.5 g vanillin per liter, which resulted in a faster late batch phase growth rate and increased biomass yield. At concentrations of 1 g/1 or higher, furfural was the least inhibitory to growth, followed by syringaldehyde. Vanillin most severely reduced specific growth rate. All three inhibitors reduced xylitol production rate approximately to the same degree.

    Full Text Available We report here the first case of indigenous tularemia detected in The Netherlands, a nonendemic country, since 1953. Whole genome DNA sequence analysis assigned the isolate BD11-00177 to the genomic group B.FTNF002-00, which previously has been exclusively reported from Spain, France, Italy, Switzerland, and Germany. The patient had not been abroad for years, which implies that this is an indigenous infection. The current case might predict an upcoming distribution of Francisella tularensis holarctica genomic group B.FTNF002-00 in Europe.

  7. The Double Binds of Indigeneity and Indigenous Resistance

    Full Text Available During the twentieth century, indigenous peoples have often embraced the category of indigenous while also having to face the ambiguities and limitations of this concept. Indigeneity, whether represented by indigenous people themselves or others, tends to face a “double bind”, as defined by Gregory Bateson, in which “no matter what a person does, he can’t win.” One exit strategy suggested by Bateson is meta-communication—communication about communication—in which new solutions emerge from a questioning of system-internal assumptions. We offer case studies from Ecuador, Peru and Alaska that chart some recent indigenous experiences and strategies for such scenarios.

    2015-08-01

    Full Text Available In this work we analyze the spoiling potential of Meyerozyma guilliermondii in yogurt. The analysis was based on contaminated samples sent to us by an industrial laboratory over two years. All the plain and fruit yogurt packages were heavily contaminated by yeasts, but only the last ones, containing fermentable sugars besides lactose, were spoiled by gas swelling. These strains were unable to grow and ferment lactose (as the type strain; they did grow on lactate plus galactose, fermented glucose and sucrose, and galactose (weakly, but did not compete with lactic acid bacteria for lactose. This enables them to grow in any yogurt, although only those with added jam were spoiled due to the fermentation of the fruit sugars. Fermentation, but not growth, was strongly inhibited at 8 °C. In consequence, in plain yogurt as well as in any yogurt maintained at low temperature, yeast contamination would not be detected by the consumer. The risk could be enhanced because the species has been proposed for biological control of fungal infections in organic agriculture. The combination of the IGS PCR-RFLP (amplification of the intergenic spacer region of rDNA followed by restriction fragment length polymorphism analysis method and mitochondrial DNA-RFLP makes a good tool to trace and control the contamination by M. guilliermondii.

    Full Text Available Parenting may be influenced by ethnicity; marginalization; education; and poverty. A critical but unexamined question is how these factors may interact to compromise or support parenting practices in ethnic minority communities. This analysis examined associations between mothers’ stimulating parenting practices and a range of child-level (age; sex; and cognitive and socio-emotional development; household-level (indigenous ethnicity; poverty; and parental education; and community-level (economic marginalization and majority indigenous population variables among 1893 children ages 4–18 months in poor; rural communities in Mexico. We also explored modifiers of associations between living in an indigenous community and parenting. Key findings were that stimulating parenting was negatively associated with living in an indigenous community or family self-identification as indigenous (β = −4.25; SE (Standard Error = 0.98; β = −1.58; SE = 0.83 respectively. However; living in an indigenous community was associated with significantly more stimulating parenting among indigenous families than living in a non-indigenous community (β = 2.96; SE = 1.25. Maternal education was positively associated with stimulating parenting only in indigenous communities; and household crowding was negatively associated with stimulating parenting only in non-indigenous communities. Mothers’ parenting practices were not associated with child sex; father’s residential status; education; or community marginalization. Our findings demonstrate that despite greater community marginalization; living in an indigenous community is protective for stimulating parenting practices of indigenous mothers.

    Full Text Available Increasing Indigenous health care professional presence in health care aims to reduce health inequities of Indigenous Peoples in Canada. Nurses are the largest health professional group and nurse graduates the main source of recruitment. The quality of graduate transition to practice is evident in the literature; however, little is reported about Indigenous new graduates. We describe using Indigenous methodology and two-eyed seeing (Indigenous and Western perspectives in exploring Indigenous transition experiences. Talking circles provided a safe environment for nurses, nurse educators and students, health managers, and policy makers to discuss Indigenous new graduate case scenarios. The methodology was critical in identifying challenges faced, recommendations for change, and a new collective commitment for cultural safety education, and ethical and respectful relationships within education, practice, and policy.

    2017-01-01

    Fungi elaborate a variety of plant-hydrolyzing enzymes including cellulases, xylanases, pectinases and amylases. Although these enzymes have potential biotechnological applications, their production at industrial level is limited because of higher costs of the purified substrates. Hence, the present study was aimed to explore the novel, natural and cheaper substrates for enzyme production. Indigenously isolated fungal strains of Aspergillus sp. were grown on banana-peels, grapefruit-peels, pomegranate-peels, sugarcane bagasse, Eucalyptus camaldulensis-leaves and shoots of two halophytic plants including Halopyrum mucronatum and Desmostachya bipinnata under solid-state fermentation (SSF) and submerged fermentation (Smf) conditions. The crude enzyme preparation was screened for cellulase (endoglucanase, beta-glucosidase and filter-paperase), hemicellulase (xylanase), pectinase and amylase production. The results revealed that among all investigated enzymes, the xylanase titers were highest using D. bipinnata- shoots and H. mucronatum- shoots as substrates under solid state fermentation conditions, suggesting their exploitation at commercial scale.

    Arun Kumar Acharya

    2012-01-01

    Full Text Available In Mexico, rural to urban migration is a clearly noticeable phenomenon. During the last few years, there has been spontaneous growth in the migration of indigenous people towards the northern cities of Mexico, especially to Monterrey, in search of employment. Once the migrants arrive in this metropolis, they face difficulties adjusting and adapting to the city environment because of hidden discrimination. The main argument and hypothesis of this paper is that indigenous people isolate themselves and segregate themselves socially due to fear of (cultural and racial discrimination and violence. For this study, data were obtained from fieldwork carried out during 2009 and 2010 in Monterrey, Mexico, where we interviewed 350 indigenous people that had moved there from different parts of the country.

    2017-10-13

    To investigate the inhibitory effect of indigenous enterobacteria on pathogenic Escherichia coli, a challenge trial with postweaning pigs was conducted. A pathogenic E. coli strain was administered to all animals and their health was closely monitored thereafter. Faecal samples were taken from three healthy and three diarrhoeic animals. Samples were cultivated on MacConkey agar and isolates were subcultured. A soft agar overlay assay was used to determine the inhibitory activity of the isolates. A total of 1,173 enterobacterial isolates were screened for their ability to inhibit the E. coli challenge strain. Colony forming units of enterobacteria on MacConkey agar were not different between healthy and diarrhoeic animals in the original samples. Furthermore, numbers of isolates per animal were also not significantly different between healthy (482 isolates) and diarrhoeic animals (691 isolates). A total of 43 isolates (3.7%) with inhibitory activity against the pathogenic E. coli challenge strain were detected. All inhibitory isolates were identified as E. coli via MALDI-TOF. The isolates belonged to the phylotypes A, C and E. Many isolates (67.4%) were commensal E. coli without relevant porcine pathogenic factors, but toxin- and fimbrial genes (stx2e, fae, estIb, elt1a, fas, fan) were detected in 14 inhibitory isolates. Healthy animals showed significantly (P=0.003) more inhibitory isolates (36 of 482 isolates; 7.5%) than diseased animals (7 of 691 isolates; 1.0%). There were no significant correlations regarding phylotype or pathogenic factors between healthy and diseased animals. This study has shown that a small proportion of indigenous E. coli is able to inhibit in vitro growth of a pathogenic E. coli strain in pigs. Furthermore, healthy animals possess significantly more inhibitory E. coli strains than diarrhoeic animals. The inhibition of pathogenic E. coli by specific indigenous E. coli strains may be an underlying principle for the containment of pathogenic

    2016-02-01

    Globally, the extraction of minerals and fossil fuels is increasingly penetrating into isolated regions inhabited by indigenous peoples, potentially undermining their livelihoods and well-being. To provide new insight to this issue, we draw on a unique longitudinal dataset collected in the Ecuadorian Amazon over an 11-year period from 484 indigenous households with varying degrees of exposure to oil extraction. Fixed and random effects regression models of the consequences of oil activities for livelihood outcomes reveal mixed and multidimensional effects. These results challenge common assumptions about these processes and are only partly consistent with hypotheses drawn from the Dutch disease literature.

    The Peruvian Amazon is culturally and biologically one of the most diverse regions on Earth. Since the 1920s oil exploration and extraction in the region have threatened both biodiversity and indigenous peoples, particularly those living in voluntary isolation. We argue that the phenomenon of peak oil, combined with rising demand and consumption, is now pushing oil extraction into the most remote corners of the world. Modern patterns of production and consumption and high oil prices are forcing a new oil exploratory boom in the Peruvian Amazon. While conflicts spread on indigenous territories, new forms of resistance appear and indigenous political organizations are born and become more powerful. The impacts of oil exploration and exploitation and indigenous resistance throughout the oil history of the Peruvian Amazon are reviewed here, focusing on the Achuar people in Rio Corrientes. The driving forces, impacts, and responses to the current oil exploration boom are analyzed from an environmental justice perspective. We conclude that, in a context of peak oil and growing global demand for oil, such devastating effects for minor quantities of oil are likely to increase and impact other remote parts of the world.

    The present research was designed to explore indigenous probiotic Lactic acid bacteria from traditional fermented foods and beverages of North-western Himalayas for their probiotic potential. It was achieved through a step-by step approach focused on the technological characterization, evaluation of the probiotic traits and adherence ability. Fifty one LAB isolates from traditional fermented foods and beverages were initially screened for their technological properties and among them twenty isolates were selected. These isolates were further characterized and identified using 16S rRNA gene sequencing as Lactobacillus brevis (7 isolates), Lactobacillus casei (5), Lactobacillus paracasei (2), Lactobacillus buchneri (1), Lactobacillus plantarum (1) and Lactobacillus sp. (3). Identified isolates were evaluated by in vitro methods including survival in gastrointestinal tract, antibiotic susceptibility, antimicrobial activity, cell surface characteristics, exopolysacharride production and haemolytic activity. The results of these experiments were used as input data for Principal Component Analysis; thus, to select the most promising probiotic isolates. Three isolates (L. brevis PLA2, L. paracasei PLA8 and L. brevis PLA16) were found to be most technological relevant and promising probiotic candidates in comparison to commercial probiotic strains. L. brevis PLA2 was selected as best isolate with probiotic potential by in vitro adherence to the human intestinal HT-29 cell line.

    Candidiasis is the most prevalent fungal infection affecting human and animals all over the world. This study represents the epidemiological aspects of superficial candidiasis in outpatients and in vitro antifungal susceptibility of etiologic Candida species. Clinical samples were taken from 173 patients including skin and nail scrapings (107; 61.8%), vaginal discharge (28; 16.2%), sputum (20; 11.6%), oral swabs (7; 4.0%), bronchoalveolar lavage (6; 3.5%) and 1 specimen (0.6%) of each eye tumor, gastric juice, urine, biopsy and urinary catheter and confirmed as candidiasis by direct microscopy, culture and histopathology. Susceptibility patterns of the isolated Candida species were determined using the disk diffusion and broth microdilution methods. Among 173 Candida isolates, C. albicans (72.3%) was the most prevalent species followed by C. parapsilosis (11.5%). Other identified species were C. glabrata, C. krusei, C. tropicalis, C. guilliermondii, C. intermedia and C. sake. Majority of the Candida isolates were susceptible to fluconazole (95.4%) followed by 5-flucytosine (89.6%), voriconazole (78.6%) itraconazole (48.0%) and ketoconazole (42.8%). Caspofungin was the most potent antifungal drug against C. albicans (MICs; 0.062-1 μg/mL), ketoconazole for C. parapsilosis and C. tropicalis (MICs; 0.031-0.25 μg/mL) and itraconazole for C. krusei, C. glabrata and C. guilliermondii (MICs; 0.031-1 μg/mL). This study reinforces the significance of superficial candidiasis as an important fungal infection with multiple clinical presentations. Our results further indicate that susceptibility testing to commonly used antifungals is crucial in order to select the appropriate therapeutic strategies which minimize complications while improving patients' life.

    Tanner, Laura; Agius, Kendall; Darbyshire, Philip

    Hospitalisation can be a traumatic experience for any child and family but the experience can be significantly more so for Indigenous parents and children from remote areas of Australia. Despite the importance of this issue for child and family health and for Indigenous health, the hospitalisation experiences of Indigenous families and children have received almost no research attention. This paper describes selected findings from a recently completed Honours research study which used the participatory and collaborative Indigenous research approach of Dadirri to explore this question. Following a brief description of the methodology of Dadirri, the paper presents the participating families' depictions of their experiences of 'Coming Down' and 'Being in Hospital', where they revealed the extent and effects of marked culture shock. The significant cultural differences between staff and Indigenous families contributed to the parents' sense of fear, powerlessness and isolation from their child, home community and culture. For these families this isolation was not merely geographic but intricately linked to their health and wellbeing.

    Full Text Available Indigenous fish fauna of the Balkhash basin was mostly formed in the postglacial period and consists of 10 species from Cyprinidae family, 5 from Balitoridae, and 1 from Percidae. More than 20 alien fish species were introduced here during XXth century that led to eradication of indigenous fishes from the Balkhash Lake and the Ili River. Our investigations of the fish fauna during last 25 years revealed permanent shortage of living area of indigenous fishes. Nowadays fish communities from only indigenous fish species exist in some remote and isolated water bodies. Areas of all indigenous fish species are become disconnected. Reduction of habitats goes relatively slow for naked osman Gymnodiptychus dybowskii (Kessler, 1874, spotted thicklip loach Triplophysa strauchii (Kessler, 1874, and gray loach Triplophysa dorsalis (Kessler, 1872. Drastic reductions of areas were revealed for Ili marinka Schizothorax pseudoaksaiensis Herzenstein 1889, Balkhash marinka Schizothorax argentatus Kessler 1874, Severtsov’s loach Triplophysa sewerzowii (G.Nikolskii, 1938, Seven River’s minnow Phoxinus brachyurus Berg 1912, Balkhsh minnow Rhynchocypris poljakowii Kessler 1879, and Balkhash perch Perca schrenkii Kessler 1874. Marinkas, osmans and perch often become victims of overfishing and poaching of local people. In that region water resources usually are used by wasteful way and loaded with pollutants. Many indigenous fish species are able to bear relatively high level of environment pollution. Hence, the main threats for indigenous fishes are introductions of trout and sander, habitats lose and unstable hydrological regimen.

    Bioremediation is often used for in situ remediation of petroleum-contaminated sites. The primary focus of this study was on understanding the indigenous microbial community which can survive in contaminated environment and is responsible for the degradation. Diesel, toluene and naphthalene-degrading microbial consortia were isolated from diesel-contaminated soil by growing on selective hydrocarbon substrates. The presence and frequency of the catabolic genes responsible for aromatic hydrocarbon biodegradation (xylE, ndoB) within the isolated consortia were screened using polymerase chain reaction PCR and DNA-DNA colony hybridization. The diesel DNA-extract possessed both the xylE catabolic gene for toluene, and the nah catabolic gene for polynuclear aromatic hydrocarbon degradation. The toluene DNA-extract possessed only the xylE catabolic gene, while the naphthalene DNA-extract only the ndoB gene. Restriction enzyme analysis with HaeIII indicated similar restriction patterns for the xylE gene fragment between toluene DNA-extract and a type strain, Pseudomonas putida ATCC 23973. A substantial proportion (74%) of the colonies from the diesel-consortium possessed the xylE gene, and the ndoB gene (78%), while a minority (29%) of the toluene-consortium harbored the xylE gene. 59% of the colonies from the naphthalene-consortium had the ndoB gene, and did not have the xylE gene. These results indicate that the microbial population has been naturally enriched in organisms carrying genes for aromatic hydrocarbon degradation and that significant aromatic biodegradative potential exists at the site. Characterization of the population genotype constitutes a molecular diagnosis which permits the determination of the catabolic potential of the site to degrade the contaminant present. (author)

    The intrarenal renin-angiotensin system (iRAS) is implicated in the pathogenesis of hypertension, chronic kidney disease and diabetic nephropathy. Urinary angiotensinogen (uAGT) levels reflect the activity of the iRAS and are altered in women with preeclampsia. Since Indigenous Australians suffer high rates and early onset of renal disease, we hypothesised that Indigenous Australian pregnant women, like non-Indigenous women with pregnancy complications, would have altered uAGT levels. The excretion of RAS proteins was measured in non-Indigenous and Indigenous Australian women with uncomplicated or complicated pregnancies (preeclampsia, diabetes/gestational diabetes, proteinuria/albuminuria, hypertension, small/large for gestational age, preterm birth), and in non-pregnant non-Indigenous women. Non-Indigenous pregnant women with uncomplicated pregnancies, had higher uAGT/creatinine levels than non-Indigenous non-pregnant women (P pregnant women with pregnancy complications, uAGT/creatinine was suppressed in the third trimester (P pregnant women with uncomplicated pregnancies, there was no change in uAGT/creatinine with gestational age and uAGT/creatinine was lower in the 2nd and 3rd trimesters than in non-Indigenous pregnant women with uncomplicated pregnancies (P pregnant women may reflect subclinical renal dysfunction which limits the ability of the kidney to maintain sodium balance and could indicate an increased risk of pregnancy complications and/or future renal disease.

    We assessed the accuracy of species-level identification of two commercially available matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) systems (Bruker Biotyper and Vitek MS) and two conventional phenotypic methods (Phoenix 100 YBC and Vitek 2 Yeast ID) with that of rDNA gene sequencing analysis among 200 clinical isolates of commonly encountered yeasts. The correct identification rates of the 200 yeast isolates to species or complex (Candida parapsilosis complex, C. guilliermondii complex and C. rugosa complex) levels by the Bruker Biotyper, Vitek MS (using in vitro devices [IVD] database), Phoenix 100 YBC and Vitek 2 Yeast ID (Sabouraud's dextrose agar) systems were 92.5%, 79.5%, 89%, and 74%, respectively. An additional 72 isolates of C. parapsilosis complex and 18 from the above 200 isolates (30 in each of C. parapsilosis, C. metapsilosis, and C. orthopsilosis) were also evaluated separately. Bruker Biotyper system could accurately identify all C. parapsilosis complex to species level. Using Vitek 2 MS (IVD) system, all C. parapsilosis but none of C. metapsilosis, or C. orthopsilosis could be accurately identified. Among the 89 yeasts misidentified by the Vitek 2 MS (IVD) system, 39 (43.8%), including 27 C. orthopsilosis isolates, could be correctly identified Using the Vitek MS Plus SARAMIS database for research use only. This resulted in an increase in the rate of correct identification of all yeast isolates (87.5%) by Vitek 2 MS. The two species in C. guilliermondii complex (C. guilliermondii and C. fermentati) isolates were correctly identified by cluster analysis of spectra generated by the Bruker Biotyper system. Based on the results obtained in the current study, MALDI-TOF MS systems present a promising alternative for the routine identification of yeast species, including clinically commonly and rarely encountered yeast species and several species belonging to C. parapsilosis complex, C. guilliermondii complex

    During childhood and adolescence, eating habits become established which are instrumental in determining eating behavior later in life. Various authors have described the acculturation of the Mapuche people toward Western culture. The objective of this study was to analyze the eating characteristics of indigenous and non-indigenous adolescent girls in the Araucania Region of Chile. A cross-sectional design was used with a probabilistic sample of 281 adolescents comprised of 139 indigenous and 142 non-indigenous girls attending 168 elementary schools. A modified food frequency questionnaire was applied, designed to obtain information about eating habits and consumption of Mapuche foods. The eating schedules are similar in both ethnic groups, with dinner being the meal that is least consumed. Total snack consumption per week has a mean of 7 with an interquartile range (IQR) of 5 to 10 without any differences between ethnic groups; of these snacks, only 2 were healthy (IQR = 1 to 3). The indigenous girls had a higher probability of consumption of native foods including mote (boiled wheat) (OR = 2.00; IC = 0.93-4.29), muday (fermented cereal alcohol) (OR = 3.45; IC = 1.90-6.27), and yuyo (field mustard) (OR = 4.40; IC = 2.06-9.39). The study's conclusion is that the the eating habits and behavior of indigenous adolescents are similar to those of non-indigenous girls, though the former still consume more indigenous foods.

    Full Text Available The bioremediation technique for a contaminated liquid waste of heavy metals using indigenous bacteria is a convenient alternative to steps continues to be developed. The research aims to find out the effectiveness of an indigenous bacterial consortium in bioremediation of contaminated liquid waste by cadmium by ex-situ. Experiments were arranged in RAL made in ex-situ where a liquid waste industry was given five treatments, namely control and four indigenous bacterial consortia (A, D, E, and J obtained from the isolation of bacteria originating from cadmium-contaminated of waste in Pasuruan district. Furthermore conducted observations of BOD5, COD, d.o. and Cd for seven days to find out the effectiveness of bioremediation. The results showed the four indigenous bacteria consortia have the bioremediation ability to reduce levels of cadmium, BOD5, COD, and increasing levels of DO. Indigenous bacterial consortia D has the best ability of liquid industrial waste bioremediation by ex-situ. Indigenous bacterial consortia J has the best of capacity reduction levels of cadmium, then the other of indigenous bacterial consortia.

  11. Indigeneity: global and local.

    The term indigenous, long used to distinguish between those who are "native" and their "others" in specific locales, has also become a term for a geocultural category, presupposing a world collectivity of "indigenous peoples" in contrast to their various "others." Many observers have noted that the stimuli for internationalization of the indigenous category originated principally from particular nation-states-Anglo-American settler colonies and Scandinavia. All, I argue, are relevantly political cultures of liberal democracy and weighty (in different ways) in international institutional affairs. However, international indigeneity has not been supported in any unqualified way by actions taken in the name of several nation-states that were among its main points of origin. In fact, staunch resistance to the international indigenous project has recently come from four of them. In 2007, the only four voting countries to reject the main product of international indigenist activity over the past 30 years, the Declaration on the Rights of Indigenous Peoples, were Australia, the United States, Canada, and New Zealand. In these locations, forms of "indigenous relationship" emerged that launched international indigeneity and that strongly influenced international perceptions of what "indigeneity" is and who "indigenous peoples" may be. Some other countries say the model of indigenous relationship that they see represented by the "establishing" set is inapplicable to themselves (but have nonetheless had to take notice of expanding internationalist indigenism). The apparently paradoxical rejection of the draft declaration by the establishing countries is consistent with the combination of enabling and constraining forces that liberal democratic political cultures offer.

    In this study, we isolated two indigenous hydrocarbon-degrading bacteria from tarball found in Rhu Sepuluh beach, Terengganu, Malaysia. These bacteria were identified based on their physiological characteristic and 16S rRNA gene sequence analysis, and they showed 99% similarity with Cellulosimicrobium cellulans DSM 43879 and Acinetobacter baumannii ATCC 19606 respectively. Their hydrocarbon-degrading capabilities were tested using diesel-oil as sole carbon source. Results analysed using GC-MS, showed diesel-oil alkanes were degraded an average 64.4% by C. cellulans and 58.1% by A. baumannii with medium optical density reaching 0.967 (C. cellulans) and 1.515 (A. baumannii) in minimal salt media at 32°C for 10days. Individual diesel-oil alkanes were degraded between 10%-95.4% by C. cellulans and 0.2%-95.9% by A. baumannii. Both strains utilized diesel-oil for growth. The study suggests both strains are part of indigenous hydrocarbon-degrading bacteria in tarball with potential for bioremediation of oil-polluted marine environment. Copyright © 2016 Elsevier Ltd.

    To review research addressing the polymicrobial aetiology of otitis media in Indigenous Australian children in order to identify research gaps and inform best practice in effective prevention strategies and therapeutic interventions. Literature review. Studies of aspirated middle-ear fluid represented a minor component of the literature reviewed. Most studies relied upon specimens from middle-ear discharge or the nasopharynx. Culture-based middle-ear discharge studies have found that non-typeable Haemophilus influenzae and Streptococcus pneumoniae predominate, with Moraxella catarrhalis, Staphylococcus aureus and Streptococcus pyogenes isolated in a lower proportion of samples. Alloiococcus otitidis was detected in a number of studies; however, its role in otitis media pathogenesis remains controversial. Nasopharyngeal colonisation is a risk factor for otitis media in Indigenous infants, and bacterial load of otopathogens in the nasopharynx can predict the ear state of Indigenous children. Most studies have used culture-based methods and specimens from middle-ear discharge or the nasopharynx. Findings from these studies are consistent with international literature, but reliance on culture may incorrectly characterise the microbiology of this condition. Advances in genomic technologies are now providing microbiologists with the ability to analyse the entire mixed bacterial communities ('microbiomes') of samples obtained from Indigenous children with otitis media.

  14. A Comparative Analysis of Indigenous Research Guidelines to Inform Genomic Research in Indigenous Communities

    2012-05-01

    Full Text Available BACKGROUND: Genetic research has potential benefits for improving health, such as identifying molecular characteristics of a disease, understanding disease prevalence and treatment, and developing treatments tailored to patients based on individual genetic characteristics of their disease. Indigenous people are often targeted for genetic research because genes are easier to study in communities that practice endogamy. Therefore, populations perceived to be more homogenous, such as Indigenous peoples, are ideal for genetic studies. While Indigenous communities remain the focal point of many genomic studies, some result in harm and unethical practice. Unfortunately, the harms of poorly formulated and unethical research involving Indigenous people have created barriers to participation that prevent critical and lifesaving research. These harms have led a number of Indigenous communities to develop guidelines for engaging with researchers to assist in safely bridging the gap between genetic research and Indigenous peoples.SPECIFIC AIMS: The specific aims of this study were: (1 to conduct an international review and comparison of Indigenous research guidelines that highlight topics regarding genetics and use of biological samples and identify commonalities and differences among ethical principles of concern to Indigenous peoples; and (2 develop policy recommendations for Indigenous populations interested in creating formal policies around the use of genetic information and protection of biological samples using data from specific aim 1.METHODS: A comparative analysis was performed to identify best research practices and recommendations for Indigenous groups from four countries: Canada, New Zealand, Australia, and the United States. The analysis examined commonalities in political relationships, which support self-determination among these Indigenous communities to control their data. Current international Indigenous guidelines were analyzed to review

  15. The politics of indigeneity: Indigenous strategies for inclusion in climate change negotiations

    Full Text Available Indigenous environmental activists have clearly articulated their views on global climate change policy. The content of these views was explored during the 10-day 2008 World Conservation Congress (WCC in Barcelona. Data were primarily collected through interviews and participant observation. In addition, policy statements and declarations made by indigenous environmental activists from 2000 to 2009 were analysed to place the perspectives of indigenous leaders and environmental activists in the context of their decade-long struggle to gain negotiating power at the United Nations Framework Convention on Climate Change. This study examines the rhetorical strategies indigenous leaders from around the world use to gain political recognition and legitimacy in climate change negotiations. Two core principles, relating to a particular representation of indigenous environmental knowledge are identified as fundamental rhetorical tools. These are a belief that the earth is a living being with rights and the conviction that it is the responsibility of indigenous peoples to protect the earth from over-exploitation. However, reference to indigenous environmental knowledge is not the only rhetorical mechanism used by indigenous leaders in the climate debates. When faced with specific United Nations policies to combat climate change that could have a profound impact on their land rights, some indigenous leaders adopt a more confrontational response. Fearing that new polices would reinforce historical trends of marginalisation, indigenous leaders seeking recognition in climate change debates speak less about their ecological knowledge and responsibility to the earth and more about their shared histories of political and economic marginalisation and land dispossession, experienced first through colonialism and more recently through globalisation.

    To quantify the independent roles of geography and Indigenous status in explaining disparities in Potentially Preventable Hospital (PPH) admissions between Indigenous and non-Indigenous Australians. Analysis of linked hospital admission data for New South Wales (NSW), Australia, for the period July 1 2003 to June 30 2008. Age-standardised admission rates, and rate ratios adjusted for age, sex and Statistical Local Area (SLA) of residence using multilevel models. PPH diagnoses accounted for 987,604 admissions in NSW over the study period, of which 3.7% were for Indigenous people. The age-standardised PPH admission rate was 76.5 and 27.3 per 1,000 for Indigenous and non-Indigenous people respectively. PPH admission rates in Indigenous people were 2.16 times higher than in non-Indigenous people of the same age group and sex who lived in the same SLA. The largest disparities in PPH admission rates were seen for diabetes complications, chronic obstructive pulmonary disease and rheumatic heart disease. Both rates of PPH admission in Indigenous people, and the disparity in rates between Indigenous than non-Indigenous people, varied significantly by SLA, with greater disparities seen in regional and remote areas than in major cities. Higher rates of PPH admission among Indigenous people are not simply a function of their greater likelihood of living in rural and remote areas. The very considerable geographic variation in the disparity in rates of PPH admission between Indigenous and non-Indigenous people indicates that there is potential to reduce unwarranted variation by characterising outlying areas which contribute the most to this disparity.

    Full Text Available The objective of this study was to confirm the antimycotic potential of a diterpenoid compound taxoquinone, isolated from Metasequoia glyptostroboides against pathogenic isolates of Candida species. The taxoquinone (100 μg/disc displayed potential anticandidal effect against Candia albicans KBN06P00076, KBN06P00074, C. glabrata KBN06P00066, KBN06P00068, C. tropicalis KBN06P00682, KBN06P00058, C. parapsilosis KBN06P00060, KBN06P00055, and C. guilliermondii KBN06P00492 and KBN06P00867 as a diameter of zones of inhibition, found in the range of 10 ± 0.6 to 13 ± 1.1 mm. The minimum inhibitory and minimum fungicidal concentrations of taxoquinone against the tested clinical isolates were found in the range of 125 to 500 and 125 to 1,000 μg/mL, respectively. On the viable counts of the tested fungal isolates, the taxoquinone evoked a remarkable anticandidal effect. Elaborative study of SEM revealed potential detrimental effect of taxoquinone on the morphology of C. parapsilosis KBN06P00060 at MIC concentration. These findings confirmed therapeutic potential of taxoquinone.

    Vulvovaginal candidiasis (VVC) is a common problem in women. The purpose of this study was to identify Candida isolates by matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) from women with vulvovaginitis that were referred to Ghaem Hospital, Mashhad, Iran. This study was conducted on 65 clinical samples isolated from women that were referred to Ghaem Hospital. All specimens were identified using phenotyping techniques, such as microscopy and culture on Sabouraud dextrose agar and corn meal agar. In addition, all isolates were processed for MALDI-TOF MS identification. Out of the 65 analyzed isolates, 61 (94%) samples were recognized by MALDI-TOF MS. However, the remaining four isolates (6%) had no reliable identification. According to the results, C. albicans (58.5%) was the most frequently isolated species, followed by C. tropicalis (16.9%), C. glabrata (7.7%), C. parapsilosis (7.7%), and guilliermondii (3.1%). As the findings indicated, MALDI TOF MS was successful in the identification of clinical Candida species. C. albicans was identified as the most common Candida species isolated from the women with VVC. Moreover, C. tropicalis was the most common species among the non- albicans Candida species.

    Full Text Available Indigenous children and young people are overrepresented in the Australian out-of-home care (OOHC system. To date, specific research has not been undertaken on workers' perspectives regarding the Indigenous-specific and non-Indigenous supports and services available to Indigenous young people exiting the system. This exploratory research involved focus group consultations with workers from seven child and family welfare agencies to examine the current support services available to Indigenous young people who are in or will be leaving out-of-home care in the State of Victoria. Findings suggest that Aboriginal Community Controlled Organisations (ACCOs play a positive role in working with non-Indigenous agencies to assist Indigenous care leavers. Participants identified some key strategies to improve outcomes, such as facilitating stronger relationships between Indigenous and non-Indigenous services, and improving the resourcing of ACCOs.

    Yeast, lactic acid bacteria (LAB) and acetic acid bacteria (AAB) populations, isolated from cocoa bean heap and box fermentations in West Africa, have been investigated. The fermentation dynamicswere determined by viable counts, and 106 yeasts, 105 LAB and 82 AAB isolateswere identified by means of rep-PCR grouping and sequencing of the rRNA genes. During the box fermentations, the most abundant species were Saccharomyces cerevisiae, Candida ethanolica, Lactobacillus fermentum, Lactobacillus plantarum, Acetobacter pasteurianus and Acetobacter syzygii, while S. cerevisiae, Schizosaccharomyces pombe, Hanseniaspora guilliermondii, Pichia manshurica, C. ethanolica, Hanseniaspora uvarum, Lb. fermentum, Lb. plantarum, A. pasteurianus and Acetobacter lovaniensis were identified in the heap fermentations. Furthermore, the most abundant species were molecularly characterized by analyzing the rep-PCR profiles. Strains grouped according to the type of fermentations and their progression during the transformation process were also highlighted. The yeast, LAB and AAB isolates were physiologically characterized to determine their ability to grow at different temperatures, as well as at different pH, and ethanol concentrations, tolerance to osmotic stress, and lactic acid and acetic acid inhibition. Temperatures of 45 °C, a pH of 2.5 to 3.5, 12% (v/v) ethanol and high concentrations of lactic and acetic acid have a significant influence on the growth of yeasts, LAB and AAB. Finally, the yeastswere screened for enzymatic activity, and the S. cerevisiae, H. guilliermondii, H. uvarumand C. ethanolica species were shown to possess several enzymes that may impact the quality of the final product.

    Caries and chronic periodontitis are common oral diseases where a higher Candida colonization is reported. Antifungal agents could be adjuvant drugs for the therapy of both clinical conditions. The aim of the current study has been to evaluate the in vitro activities of conventional and new antifungal drugs against oral Candida isolates from patients suffering from caries and/or chronic periodontitis. In vitro activities of amphotericin B, fluconazole, itraconazole, miconazole, nystatin, posaconazole and voriconazole against 126 oral Candida isolates (75 Candida albicans, 18 Candida parapsilosis, 11 Candida dubliniensis, six Candida guilliermondii, five Candida lipolytica, five Candida glabrata, four Candida tropicalis and two Candida krusei) from 61 patients were tested by the CLSI M27-A3 method. Most antifungal drugs were highly active, and resistance was observed in less than 5% of tested isolates. Miconazole was the most active antifungal drug, being more than 98% of isolates susceptible. Fluconazole, itraconazole, and the new triazoles, posaconazole and voriconazole, were also very active. Miconazole, fluconazole and voriconazole have excellent in vitro activities against all Candida isolates and could represent suitable treatment for a hypothetically adjunctive therapy of caries and chronic periodontitis.

    It is estimated that there are 370 million indigenous peoples in 90 countries globally. Indigenous peoples generally face substantial disadvantage and poorer health status compared with nonindigenous peoples. Population-level cancer surveillance provides data to set priorities, inform policies, and monitor progress over time. Measuring the cancer burden of vulnerable subpopulations, particularly indigenous peoples, is problematic. There are a number of practical and methodological issues potentially resulting in substantial underestimation of cancer incidence and mortality rates, and biased survival rates, among indigenous peoples. This, in turn, may result in a deprioritization of cancer-related programs and policies among these populations. This commentary describes key issues relating to cancer surveillance among indigenous populations including 1) suboptimal identification of indigenous populations, 2) numerator-denominator bias, 3) problems with data linkage in survival analysis, and 4) statistical analytic considerations. We suggest solutions that can be implemented to strengthen the visibility of indigenous peoples around the world. These include acknowledgment of the central importance of full engagement of indigenous peoples with all data-related processes, encouraging the use of indigenous identifiers in national and regional data sets and mitigation and/or careful assessment of biases inherent in cancer surveillance methods for indigenous peoples.

    The echinocandin antifungal drugs inhibit synthesis of the major fungal cell wall polysaccharide β(1,3)-glucan. Echinocandins have good efficacy against Candida albicans but reduced activity against other Candida species, in particular Candida parapsilosis and Candida guilliermondii. Treatment of Candida albicans with a sub-MIC level of caspofungin has been reported to cause a compensatory increase in chitin content and to select for sporadic echinocandin-resistant FKS1 point mutants that also have elevated cell wall chitin. Here we show that elevated chitin in response to caspofungin is a common response in various Candida species. Activation of chitin synthesis was observed in isolates of C. albicans, Candida tropicalis, C. parapsilosis, and C. guilliermondii and in some isolates of Candida krusei in response to caspofungin treatment. However, Candida glabrata isolates demonstrated no exposure-induced change in chitin content. Furthermore, isolates of C. albicans, C. krusei, C. parapsilosis, and C. guilliermondii which were stimulated to have higher chitin levels via activation of the calcineurin and protein kinase C (PKC) signaling pathways had reduced susceptibility to caspofungin. Isolates containing point mutations in the FKS1 gene generally had higher chitin levels and did not demonstrate a further compensatory increase in chitin content in response to caspofungin treatment. These results highlight the potential of increased chitin synthesis as a potential mechanism of tolerance to caspofungin for the major pathogenic Candida species. PMID:23089748

    Full Text Available We assessed the accuracy of species-level identification of two commercially available matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS systems (Bruker Biotyper and Vitek MS and two conventional phenotypic methods (Phoenix 100 YBC and Vitek 2 Yeast ID with that of rDNA gene sequencing analysis among 200 clinical isolates of commonly encountered yeasts. The correct identification rates of the 200 yeast isolates to species or complex (Candida parapsilosis complex, C. guilliermondii complex and C. rugosa complex levels by the Bruker Biotyper, Vitek MS (using in vitro devices [IVD] database, Phoenix 100 YBC and Vitek 2 Yeast ID (Sabouraud's dextrose agar systems were 92.5%, 79.5%, 89%, and 74%, respectively. An additional 72 isolates of C. parapsilosis complex and 18 from the above 200 isolates (30 in each of C. parapsilosis, C. metapsilosis, and C. orthopsilosis were also evaluated separately. Bruker Biotyper system could accurately identify all C. parapsilosis complex to species level. Using Vitek 2 MS (IVD system, all C. parapsilosis but none of C. metapsilosis, or C. orthopsilosis could be accurately identified. Among the 89 yeasts misidentified by the Vitek 2 MS (IVD system, 39 (43.8%, including 27 C. orthopsilosis isolates, could be correctly identified Using the Vitek MS Plus SARAMIS database for research use only. This resulted in an increase in the rate of correct identification of all yeast isolates (87.5% by Vitek 2 MS. The two species in C. guilliermondii complex (C. guilliermondii and C. fermentati isolates were correctly identified by cluster analysis of spectra generated by the Bruker Biotyper system. Based on the results obtained in the current study, MALDI-TOF MS systems present a promising alternative for the routine identification of yeast species, including clinically commonly and rarely encountered yeast species and several species belonging to C. parapsilosis complex, C. guilliermondii

    Cunninghamella blakesleeana- JSK2, a gamma-linolenic acid (GLA) producing tropical fungal isolate, was utilized as a tool to evaluate the influence of various plant seed oils on biomass, oleagenicity and bio-fuel production. The fungus accumulated 26 % total lipid of their dry biomass (2 g/l) and 13 % of GLA in its total fatty acid. Among the various plant seed oils tested as carbon sources for biotransformation studies, watermelon oil had an effect on biomass and total lipid increasing up to 9.24 g/l and 34 % respectively. Sunflower, pumpkin, and onion oil increased GLA content between 15-18 %. Interestingly, an indigenous biodiesel commodity, Pongamia pinnata oil showed tremendous effect on fatty acid profile in C. blakesleeana- JSK2, when used as a sole source of carbon. There was complete inhibition of GLA from 13 to 0 % and increase in oleic acid content, one of the key components of biodiesel to 70 % (from 20 % in control). Our results suggest the potential application of indigenous plant seed oils, particularly P. pinnata oil, for the production of economically valuable bio-fuel in oleaginous fungi in general, and C. blakesleeana- JSK2, in particular.

    Full Text Available Background: The incidence of mosquito-borne diseases and the resistance of mosquitoes to conventional pesticides have recently caused a panic to the authorities in the endemic countries. This study was conducted to identify native larvicidal biopesticides against Culex pipiens for utilization in the battle against mosquito-borne diseases.Methods: Larvicidal activities of new indigenous Bacillus thuringiensis isolates and crude toxin complexes (TCs of two nematode bacterial-symbionts, Photorhabdus luminescens akhurstii (HRM1 and Ph. luminescens akhurstii (HS1 that tested against Cx. pipiens. B. thuringiensis isolates were recovered from different environmental samples in Saudi Arabia, and the entomopathogenic nematodes, Heterorhabditis indica (HRM1 and He. sp (HS1 were iso­lated from Egypt. Larvicidal activities (LC50 and LC95 of the potentially active B. thuringiensis strains or TCs were then evaluated at 24 and 48h post-treatment.Results: Three B. thuringiensis isolates were almost as active as the reference B. thuringiensis israelensis (Bti-H14, and seven isolates were 1.6–5.4 times more toxic than Bti-H14. On the other hand, the TCs of the bacterial sym­bionts, HRM1 and HS1, showed promising larvicidal activities. HS1 showed LC50 of 2.54 folds that of HRM1 at 24h post-treatment. Moreover, histopathological examinations of the HS1-treated larvae showed deformations in midgut epithelial cells at 24h post-treatment.Conclusion: Synergistic activity and molecular characterization of these potentially active biocontrol agents are currently being investigated. These results may lead to the identification of eco-friend mosquito larvicidal product(s that could contribute to the battle against mosquito-borne diseases.

    The gambling activities of minority groups such as Indigenous peoples are usually culturally complex and poorly understood. To redress the scarcity of information and contribute to a better understanding of gambling by Indigenous people, this paper presents quantitative evidence gathered at three Australian Indigenous festivals, online and in several Indigenous communities. With support from Indigenous communities, the study collected and analyzed surveys from 1,259 self-selected Indigenous adults. Approximately 33 % of respondents gambled on card games while 80 % gambled on commercial gambling forms in the previous year. Gambling participation and involvement are high, particularly on electronic gaming machines (EGMs), the favorite and most regular form of gambling. Men are significantly more likely to participate in gambling and to gamble more frequently on EGMs, horse/dog races, sports betting and instant scratch tickets. This elevated participation and frequency of gambling on continuous forms would appear to heighten gambling risks for Indigenous men. This is particularly the case for younger Indigenous men, who are more likely than their older counterparts to gamble on EGMs, table games and poker. While distinct differences between the gambling behaviors of our Indigenous sample and non-Indigenous Australians are apparent, Australian Indigenous behavior appears similar to that of some Indigenous and First Nations populations in other countries. Although this study represents the largest survey of Indigenous Australian gambling ever conducted in New South Wales and Queensland, further research is needed to extend our knowledge of Indigenous gambling and to limit the risks from gambling for Indigenous peoples.

    During wet processing of coffee, the ripe cherries are pulped, then fermented and dried. This study reports an experimental approach for target identification and selection of indigenous coffee yeasts and their potential use as starter cultures during the fermentation step of wet processing. A total of 144 yeast isolates originating from spontaneously fermenting coffee beans were identified by molecular approaches and screened for their capacity to grow under coffee-associated stress conditions. According to ITS-rRNA gene sequencing, Pichia fermentans and Pichia kluyveri were the most frequent isolates, followed by Candida Candida glabrata, quercitrusa, Saccharomyces sp., Pichia guilliermondii, Pichia caribbica and Hanseniaspora opuntiae. Nine stress-tolerant yeast strains were evaluated for their ability to produce aromatic compounds in a coffee pulp simulation medium and for their pectinolytic activity. P. fermentans YC5.2 produced the highest concentrations of flavor-active ester compounds (viz., ethyl acetate and isoamyl acetate), while Saccharomyces sp. YC9.15 was the best pectinase-producing strain. The potential impact of these selected yeast strains to promote flavor development in coffee beverages was investigated for inoculating coffee beans during wet fermentation trials at laboratory scale. Inoculation of a single culture of P. fermentans YC5.2 and co-culture of P. fermentans YC5.2 and Saccharomyces sp. YC9.15 enhanced significantly the formation of volatile aroma compounds during the fermentation process compared to un-inoculated control. The sensory analysis indicated that the flavor of coffee beverages was influenced by the starter cultures, being rated as having the higher sensory scores for fruity, buttery and fermented aroma. This demonstrates a complementary role of yeasts associated with coffee quality through the synthesis of yeast-specific volatile constituents. The yeast strains P. fermentans YC5.2 and Saccharomyces sp. YC9.15 have a great

    1997-09-01

    This article focuses on the impact of colonisation and its associated impact on Indigenous teaching and learning. Western European institutions have dominated Indigenous ways of knowing and in Australia this has led to barriers which restrict the participation of Aboriginal people in education systems. Globally Indigenous people are attempting to bring into the introduced educational systems culturally appropriate teaching and learning practices so that a more holistic approach to education can become the norm rather than the exception. The relationship between Indigenous knowledge and western European concepts of knowledge and knowing need to placed in a framework of mutual interaction so that not only do Indigenous people benefit, but so do non-Indigenous educators and students.

    Irradiating the rice straw with high dose level of gamma rays (100-KGy) after being treated with diluted sulphuric acid increased the xylitol yields from the hydrolysates to 43.2 and 45.0 g/l out of 63.0 g/l xylose by Candida tropical and Candida guilliermondii, respectively. Meanwhile, irradiating C. tropical is and C. guilliermondii with low dose levels (0.25 and 0.5 KGy, respectively) before being inoculated in artificial medium, containing 150 g/l xylose, increased the yields of xylitol by the irradiated species. On the contrary, the produced xylitol was decreased sharply in case of isolates irradiated with 1 KGy especially C. tropical is, which showed less resistance to gamma rays recording. D 1 0, value 1.225 compared with 1.608 for C. guilliermondii. Sub-lethal dose of gamma rays (10 and 8 KGy) shrank C. guilliermondii cells and their sh,ape became irregular while C. tropical is cells formed small cottony fibres structure on the external surface of the cell wall, respectively. Meanwhile, lethal radiation doses-(l l and 9 KGy) caused deformation of the vegetative cells of both isolates. Many cells were enlarged, the cell walls of many others were ruptured and the internal contents were released outside the cells. Complete lyses of some cells-was also observed

    Barker, Brittany; Goodman, Ashley; DeBeck, Kora

    2017-06-16

    In Canada, Indigenous youth suicide represents one of several health disparities burdening Indigenous populations, and like many other of these disparities, can be understood as an expression of societal, historical, cultural and familial trauma. As the number of Indigenous youth who take their own lives every year in Canada continues to far exceed national averages, it appears that conventional suicide prevention efforts remain ineffective among this population. A growing body of research argues that conventional interventions, largely rooted in Western individual-level behavioural change frameworks, are culturally discordant with Indigenous paradigms. In response, some Indigenous communities are turning to cultural revitalization as a holistic community-driven response to suicide prevention and treatment. The following commentary explores the emerging evidence base for "culture as treatment" - a novel approach to suicide that emphasizes the significance of interconnectedness in healing, alongside the revitalization of traditional values to reclaim community wellness. In doing so, we seek to contribute to a changing discourse surrounding Indigenous youth suicide by acknowledging culture as strength against this national crisis.

    Full Text Available The education in the indigenous schools, even though it is build within the legal framework of the State and a modern concept of education, demands new comprehensions from the western society not only in its relation with the indigenous education, but also in its relation with the indigenous people. Because of its condition as a mediator between two different forms of thinking, the indigenous school also represents a fertile ground to think about the western conceptions of education. This article is dedicated to a deeper reflection about some aspects of the relation between the western society, based on rationality and science, and the indian people in the construction of the indigenous schools.

    Full Text Available Biocontrol using plant growth-promoting rhizobacteria (PGPR represents an alternative approach to disease management, since PGPR are known to promote growth and reduce diseases in various crops. Among the different PGPR, members of the genus Bacillus are prefered for most biotechnological uses due to their capability to form extremely resistant spores and produce a wide variety of metabolites with antimicrobial activity. The objective of this research was to identify antagonistic bacteria for management of the plant diseases. Eleven isolates of Bacillus spp. were obtained from the soil samples collected from different localities in the Province of Vojvodina. The antifungal activity of bacterial isolates against five fungal species was examined using a dual plate assay. Bacillus isolates exhibited the highest antifungal activity against Fusarium proliferatum, Fusarium oxysporum f. sp. cepae and Alternaria padwickii, while they had the least antagonistic effect on Fusarium verticillioides and Fusarium graminearum. Molecular identification showed that effective bacterial isolates were identified as Bacillus safensis (B2, Bacillus pumilus (B3, B11, Bacillus subtilis (B5, B7 and Bacillus megaterium (B8, B9. The highest antagonistic activity was exhibited by isolates B5 (from 39% to 62% reduction in fungal growth and B7 (from 40% to 71% reduction in fungal growth. These isolates of B. subtilis could be used as potential biocontrol agents of plant diseases. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. TR-31073

    2012-05-01

    Indigenous community health workers are part of a strategy developed by Brazil in the last two decades to promote a special healthcare model for indigenous peoples. Their role is designed to deal with various aspects of the special health policy, including the link between the heath team and the community and mediation between scientific and indigenous medical knowledge. Despite a significant increase in the number of indigenous community health workers in recent years, an evaluation of their responsibilities and contributions to the success of special care had not been conducted previously. This article, based on a literature review and original research by the authors, analyzes the role of the indigenous community health workers vis-à-vis their training and participation in health teams in different contexts in Brazil. Considering the importance assigned to the role of indigenous community health workers, this analysis reveals various ambiguities and contradictions that hinder both their performance and their potential contribution to the special health services.

    Little is known about the prevalence of refractive error, binocular vision, and other visual conditions in Australian Indigenous children. This is important given the association of these visual conditions with reduced reading performance in the wider population, which may also contribute to the suboptimal reading performance reported in this population. The aim of this study was to develop a visual profile of Queensland Indigenous children. Vision testing was performed on 595 primary schoolchildren in Queensland, Australia. Vision parameters measured included visual acuity, refractive error, color vision, nearpoint of convergence, horizontal heterophoria, fusional vergence range, accommodative facility, AC/A ratio, visual motor integration, and rapid automatized naming. Near heterophoria, nearpoint of convergence, and near fusional vergence range were used to classify convergence insufficiency (CI). Although refractive error (Indigenous, 10%; non-Indigenous, 16%; p = 0.04) and strabismus (Indigenous, 0%; non-Indigenous, 3%; p = 0.03) were significantly less common in Indigenous children, CI was twice as prevalent (Indigenous, 10%; non-Indigenous, 5%; p = 0.04). Reduced visual information processing skills were more common in Indigenous children (reduced visual motor integration [Indigenous, 28%; non-Indigenous, 16%; p < 0.01] and slower rapid automatized naming [Indigenous, 67%; non-Indigenous, 59%; p = 0.04]). The prevalence of visual impairment (reduced visual acuity) and color vision deficiency was similar between groups. Indigenous children have less refractive error and strabismus than their non-Indigenous peers. However, CI and reduced visual information processing skills were more common in this group. Given that vision screenings primarily target visual acuity assessment and strabismus detection, this is an important finding as many Indigenous children with CI and reduced visual information processing may be missed. Emphasis should be placed on identifying

    The disposal of hazardous crude oil tank bottom sludge (COTBS) represents a significant waste management burden for South Mediterranean countries. Currently, the application of biological systems (bioremediation) for the treatment of COTBS is not widely practiced in these countries. Therefore, this study aims to develop the potential for bioremediation in this region through assessment of the abilities of indigenous hydrocarbonoclastic microorganisms from Libyan Hamada COTBS for the biotreatment of Libyan COTBS-contaminated environments. Bacteria were isolated from COTBS, COTBS-contaminated soil, treated COTBS-contaminated soil, and uncontaminated soil using Bushnell Hass medium amended with Hamada crude oil (1 %) as the main carbon source. Overall, 49 bacterial phenotypes were detected, and their individual abilities to degrade Hamada crude and selected COBTS fractions (naphthalene, phenanthrene, eicosane, octadecane and hexane) were evaluated using MT2 Biolog plates. Analyses using average well colour development showed that ~90 % of bacterial isolates were capable of utilizing representative aromatic fractions compared to 51 % utilization of representative aliphatics. Interestingly, more hydrocarbonoclastic isolates were obtained from treated contaminated soils (42.9 %) than from COTBS (26.5 %) or COTBS-contaminated (30.6 %) and control (0 %) soils. Hierarchical cluster analysis (HCA) separated the isolates into two clusters with microorganisms in cluster 2 being 1.7- to 5-fold better at hydrocarbon degradation than those in cluster 1. Cluster 2 isolates belonged to the putative hydrocarbon-degrading genera; Pseudomonas, Bacillus, Arthrobacter and Brevundimonas with 57 % of these isolates being obtained from treated COTBS-contaminated soil. Overall, this study demonstrates that the potential for PAH degradation exists for the bioremediation of Hamada COTBS-contaminated environments in Libya. This represents the first report on the isolation of

    Despite over-representation of Indigenous Australians in sentinel studies of injecting drug use, little is known about relevant patterns of drug use and dependence. This study compares drug dependence and possible contributing factors in Indigenous and non-Indigenous Australians who inject drugs. Respondent-driven sampling was used in major cities and 'peer recruitment' in regional towns of Queensland to obtain a community sample of Indigenous (n = 282) and non-Indigenous (n = 267) injectors. Data are cross sectional. Multinomial models were developed for each group to examine types of dependence on injected drugs (no dependence, methamphetamine-dependent only, opioid-dependent only, dependent on methamphetamine and opioids). Around one-fifth of Indigenous and non-Indigenous injectors were dependent on both methamphetamine and opioids in the previous 12 months. Psychological distress was associated with dual dependence on these drugs for Indigenous [adjusted relative risk (ARR) 4.86, 95% confidence interval (CI) 2.08-11.34] and non-Indigenous (ARR 4.14, 95% CI 1.59-10.78) participants. Unemployment (ARR 8.98, 95% CI 2.25-35.82) and repeated (> once) incarceration as an adult (ARR 3.78, 95% CI 1.43-9.97) were associated with dual dependence for Indigenous participants only. Indigenous participants had high rates of alcohol dependence, except for those dependent on opioids only. The drug dependence patterns of Indigenous and non-Indigenous people who inject drugs were similar, including the proportions dependent on both methamphetamine and opioids. However, for Indigenous injectors, there was a stronger association between drug dependence and contextual factors such as unemployment and incarceration. Expansion of treatment options and community-level programs may be required. [Smirnov A, Kemp R, Ward J, Henderson S, Williams S, Dev A, Najman J M.

    Background Studies throughout North America and Europe have documented adverse perinatal outcomes for racial/ethnic minorities. Nonetheless, the contrast in newborn characteristics between indigenous and non-indigenous populations in Latin America has been poorly characterized. This is due to many challenges, including a lack of vital registration information on ethnicity. The objective of this study was to analyze trends in anthropometric measures at birth in Chilean indigenous (Mapuche) and non-indigenous children over a 5-year period. Methods We examined weight and length at birth using information available through a national data base of all birth records for the years 2000 through 2004 (n = 1,166.513). Newborns were classified ethnically according to the origins of the parents' last names. Result The average birthweight was stable over the 5 year period with variations of less than 20 g in each group, and with mean values trivially higher in indigenous newborns. The proportion weighing less than 2500 g at birth increased modestly from 5.2% to 5.6% in non-indigenous newborns whereas the indigenous births remained constant at 5.2%. In multiple regression analyses, adjusting flexibly for gestational age and maternal characteristics, the occurrence of an indigenous surname added only 14 g to an average infant's birthweight while holding other factors constant. Results for length at birth were similar, and adjusted time trend variation in both outcomes was trivially small after adjustment. Anthropometric indexes at birth in Chile are quite favorable by international standards. Conclusion There is only a trivial degree of ethnic disparity in these values, in contrast to conditions for ethnic minorities in other countries. Moreover, these values remained roughly constant over the 5 years of observation in this study. PMID:20598150

    A total of 855 yeast strains isolated from different clinical specimens, mainly nail (42%) and vulva-vagina (25%) were identified by a set of polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP). Genomic DNA was extracted from fresh colonies using Whatman FTA Card technology. PCR assays were performed on the complete ribosomal DNA internal transcribed spacer (rDNA-ITS) region for all isolates and species identification was carried out through their specific electrophoretic profiles after digestion with the enzyme MspI. Those isolates suspected as Candida parapsilosis group were then subjected to amplification of the secondary alcohol dehydrogenase (SADH) gene and restriction digestion with NlaIII enzyme. In total, 71.1% of the strains were obtained from females and 28.9% from males. The age group of 31-40 years consisted of the highest frequency of patients with candidiasis. Candida albicans was the predominant species (58.6%) followed by C. parapsilosis (11.0%), C. glabrata (8.3%), C. tropicalis (7.0%), C. kefyr (5.8%), C. krusei (4.4%), C. orthopsilosis (2.1%), and C. guilliermondii (0.6%). A few strains of C. lusitaniae, C. rugosa, C. intermedia, C. inconspicua, C. neoformans and S. cerevisiae were isolated. We could not identify 8 (0.9%) isolates. Candida albicans remains the most frequently species isolated from Iranian patients; however, the number of non-C. albicans Candida species looks to be increasing. The simple and reliable PCR-RFLP system used in the study has the potential to identify most clinically isolated yeasts.

    Full Text Available In this article, the educational attainment of Indigenous peoples of working age (25 to 64 years in Canada is examined. This diverse population has typically had lower educational levels than the general population in Canada. Results indicate that, while on the positive side there are a greater number of highly educated Indigenous peoples, there is also a continuing gap between Indigenous and non-Indigenous peoples. Data also indicate that the proportion with less than high school education declined, which corresponds with a rise of those with a PSE; the reverse was true in 1996. Despite these gains, however, the large and increasing absolute numbers of those without a high school education is alarming. There are intra-Indigenous differences: First Nations with Indian Status and the Inuit are not doing as well as non-Status and Métis peoples. Comparisons between the Indigenous and non-Indigenous populations reveal that the documented gap in post-secondary educational attainment is at best stagnant. Out of the data analysis, and based on the history of educational policy, we comment on the current reform proposed by the Government of Canada, announced in February of 2014, and propose several policy recommendations to move educational attainment forward.

    The purpose of this paper is to compare the use of drugs and alcohol by Indigenous and non-Indigenous prisoners and examine relevant treatment in Australian prisons. Prison authorities were surveyed about alcohol and drug use by prisoners prior to and during imprisonment and drug and alcohol treatment programs in prison. The literature was review for information on alcohol and drug use and treatment in Australian prisons. In 2009, over 80 percent of Indigenous and non-Indigenous inmates smoked. Prior to imprisonment, many Indigenous and non-Indigenous inmates drank alcohol at risky levels (65 vs 47 percent) and used illicit drugs (over 70 percent for both groups). Reports of using heroin (15 vs 21 percent), ATS (21 vs 33 percent), cannabis (59 vs 50 percent) and injecting (61 vs 53 percent) were similarly high for both groups. Prison-based programs included detoxification, Opioid Substitution Treatment, counselling and drug free units, but access was limited especially among Indigenous prisoners. Drug and alcohol use was a significant issue in Australian prisons. Prisoners were over five times more likely than the general population to have a substance use disorder. Imprisonment provides an important opportunity for rehabilitation for offenders. This opportunity is especially relevant to Indigenous prisoners who were more likely to use health services when in prison than in the community and given their vast over representations in prison populations. Given the effectiveness of treatment in reducing re-offending rates, it is important to expand drug treatment and especially culturally appropriate treatment programs for Indigenous inmates. Very little is known about Indigenous specific drug and alcohol programs in Australian prisons.

    2014-01-01

    The re-vitalization of indigenous languages depend on political and legal support and the imple-mentation of language rights depend on knowledge of vocabulary and grammar structures of the individual languages. Throughout the nineteenth century world, compilers of dictionaries adapted indigenous...... languages to match standards defined in nation-building and, thereby, enabled latent possibilities for indigenous populations to re-vitalize their languages in connection with the United Nations Year for Indigenous Peoples in 1993, and the first United Nations Decade for Indigenous Peoples, 1995......–2004. This article focuses on dictionaries of the languages of the Ainu populations in the borderlands between the nation-states Japan and Russia. The main argument is that the Ainu Cultural Promotion Act promulgated in 1997 had a significant impact on the production and purpose of Ainu dictionaries...

    Bio-treatment of wastewater mediated by microalgae is considered as a promising solution. This work aimed to isolate an indigenous microalgal strain (named MBFJNU-1) from swine wastewater effluent and identify as Chlorella vulgaris. After 12days, the removal efficiencies of total nitrogen (TN) and total phosphorus (TP) in undiluted swine slurry were 90.51% and 91.54%, respectively. Stress tolerance in response to wastewater was verified by cultivating in artificial wastewater containing different levels of chemical oxygen demand (COD), TN and TP. MBFJNU-1 could grow well in undiluted swine slurry and artificial wastewater containing 30,000mg/L COD or 2000mg/L TN. Furthermore, global nuclear DNA methylation (5-mC) of MBFJNU-1 was employed to explore the possible mechanism in response to wastewater stress. The results showed that the level of 5-mC was inversely proportional to the growth of MBFJNU-1 in different diluted swine slurry, helping to understand 5-mC variation in response to stress environment.

    There have been no previous estimates on differences in adult or overall mortality in indigenous peoples in Brazil, although such indicators are extremely important for reducing social iniquities in health in this population segment. Brazil has made significant strides in recent decades to fill the gaps in data on indigenous peoples in the national statistics. The aim of this paper is to present estimated mortality rates for indigenous and non-indigenous persons in different age groups, based on data from the 2010 Population Census. The estimates used the question on deaths from specific household surveys. The results indicate important differences in mortality rates between indigenous and non-indigenous persons in all the selected age groups and in both sexes. These differences are more pronounced in childhood, especially in girls. The indicators corroborate the fact that indigenous peoples in Brazil are in a situation of extreme vulnerability in terms of their health, based on these unprecedented estimates of the size of these differences.

Identification of species of Candida yeast was made with the use of CHROMagar Candida® and API AUX 20®. Additionally, in vitro susceptibility to fluconazole was evaluated by the agar diffusion method (CLSI, M44-A2. The prevalence of vaginal candidiasis was 23/86 cases (26.7% among women 15 to 60 years. Candida albicans was the most common species among patients (39.1%. However, other isolated agents within the same genus Candida dominated (65.2% and were identified: Complex C. glabrata (4/23; 17.4%, C. tropicalis (4/23; 17.4%, Complex C. parapsilosis (3/23; 13.1%, C.guilliermondii (2/23; 8.7%, C. krusei (1/23; 4.3% and one episode of mixed infection with C. albicans and C. krusei (1/23. No statistical difference was observed between symptoms; vulvovaginal erythema occurred in all infected women. More than half of the yeasts (15/23 were sensitive to fluconazole. In this population sample, isolates of C. albicans and C. guilliermondii were 100% sensitive to fluconazole, while the C. krusei strain (1/23 isolated from a mixed infection was resistant to this antimicotic. Other species, like C. tropicalis (4/23, C. glabrata (2/23 and Complex C. parapsilosis (1/23 showed dose-dependent susceptibility to fluconazole. In gynecological evaluations of patients from rural or urban communities, with clinical picture of micotic vulvovaginitis, a microbiological study of vaginal secretions should be implemented.

    2009-09-01

    Full Text Available The paper begins by noting the low level of reference to Indigenous Australians in the Commonwealth Constitution at the start of Federation, and goes on to discuss the limits to what was achieved by the 1967 amendments. The situation represents a marked contrast with the USA and Canada in terms of treaties and constitutional recognition. In Australia, particularly during the period of the ‘Reconciliation’ process in the 1990s, important steps were taken by Indigenous Australians to identify items of ‘unfinished business’ in a ‘Statement of Indigenous Rights’. But there has been limited progress to meet these aspirations. And Australian law still lacks a tradition of recognition of human rights generally, let alone Indigenous rights. International law, too, largely lacked recognition of human rights, generally prior to the adoption in 1945 of the Charter of the United Nations. The brief references in the Charter were subsequently developed in a range of declarations and of treaties. These applied to people generally, with scant reference to Indigenous peoples. But, since the 1970s, there has been growing international recognition of the rights of Indigenous peoples under existing declarations and treaties. Since the 1990s, in particular, the UN system has established specific mechanisms for addressing such issues. On 13 September 2007, the General Assembly finally adopted a Declaration on the Rights of Indigenous Peoples.

  3. Plant Provocations: Botanical Indigeneity and (Decolonial Imaginations

    Directory of Open Access Journals (Sweden)

    Narendran Kumarakulasingam

    Full Text Available Abstract Abstract: This paper examines the possibilities and limitations of an emergent global discourse of indigeneity to offer an oppositional praxis in the face of the depredations of settler colonialism in post-apartheid South Africa. Self-conscious articulations of indigeneity, we argue, reveal the fraught relationship between increasingly hegemonic and narrow understandings of the indigenous and the carceral logic of apartheid. We examine this by focusing on the meanings and attachments forged through indigenous plants in two realms: the world of indigenous gardening practised by white suburban dwellers and that of subsistence farming undertaken by rural black women. This juxtaposition reveals that in contrast to the pervasive resurrection of colonial time that defines metropolitan indigenous gardening, the social relations of a subsistence cultivator challenge the confines of colonial temporality, revealing a creative mode of dissent structured around dreams, ancestral knowledge, and the commons. Our exploration of struggles around botanical indigeneity suggests that anticolonial modes of indigeneity do not necessarily inhere in recognisable forms and that studies of the indigenous need to proceed beyond those that bear familial resemblance to emergent global understandings.

    Full Text Available ABSTRACT The aim of this study was to identify Candida spp. isolated from candiduria episodes at a tertiary hospital in the Midwest region of Brazil, and to determine their susceptibility profiles to antifungal compounds. From May 2011 to April 2012, Candida spp. isolated from 106 adult patients with candiduria admitted to the University Hospital of the Federal University of Mato Grosso do Sul were evaluated. Both, species identification and susceptibility testing with fluconazole-FLC, voriconazole-VRC, and amphotericin B-AmB were carried out using the Vitek 2. To discriminate species of the C. parapsilosis complex, a RAPD-PCR technique using the RPO2 primer was performed. From the total of 106 isolates, 42 (39.6% C. albicans and 64 (60.4% Candida non-albicans (CNA - 33 C. tropicalis, 18 C. glabrata, 5 C. krusei, 4 C. parapsilosis sensu stricto, 2 C. kefyr, 1 C. lusitaniae, and 1 C. guilliermondii were identified. All isolates were susceptible to AmB and VRC, whereas all C. glabrata isolates presented either resistance (5.6% or dose-dependent susceptibility (94.4% to FLC. The study of Candida spp. and their resistance profiles may help in tailoring more efficient therapeutic strategies for candiduria.

    Full Text Available Abstract Background Indigenous women in Australia have a disproportionate burden of cervical cancer despite a national cervical screening program. Prior to introduction of a national human papilloma virus (HPV vaccination program, we determined HPV genotype prevalence by Indigenous status and residence in remote areas. Methods We recruited women aged 17 to 40 years presenting to community-based primary health services for routine Pap screening across Australia. A liquid-based cytology (LBC cervical specimen was tested for HPV DNA using the AMPLICOR HPV-DNA test and a PGMY09/11-based HPV consensus PCR; positive specimens were typed by reverse hybridization. We calculated age-adjusted prevalence by weighting to relevant population data, and determined predictors of HPV-DNA positivity by age, Indigenous status and area of residence using logistic regression. Results Of 2152 women (655 Indigenous, prevalence of the high-risk HPV genotypes was similar for Indigenous and non-Indigenous women (HPV 16 was 9.4% and 10.5%, respectively; HPV 18 was 4.1% and 3.8%, respectively, and did not differ by age group. In younger age groups, the prevalence of other genotypes also did not differ, but in those aged 31 to 40 years, HPV prevalence was higher for Indigenous women (35% versus 22.5%; P Conclusion Although we found no difference in the prevalence of HPV16/18 among Australian women by Indigenous status or, for Indigenous women, residence in remote regions, differences were found in the prevalence of risk factors and some other HPV genotypes. This reinforces the importance of cervical screening as a complement to vaccination for all women, and the value of baseline data on HPV genotype prevalence by Indigenous status and residence for the monitoring of vaccine impact.

    Full Text Available Aim: The current study was the first of its kind taken upon indigenous ecotypes of the Karnataka in order to unravel the diversity details at 20 chicken microsatellite regions. Materials and Methods: 210 indigenous chicken belonging to six districts of Bangalore and Mysore division formed the target sample for the present study. The genomic deoxyribonucleic acid was isolated by phenol chloroform isoamyl alcohol method. A panel of 20 microsatellite regions, including 14 recommended by FAO and six identified from published scientific literature became the targeted chicken genomic region. 27-33 samples were successfully genotyped in each of the six ecotypes through simplex or multiplex polymerase chain reactions, polyacrylamide gel electrophoresis and silver staining for the selected microsatellite panel. Results: The chickens of Ramanagara and Chamrajnagara were most distant with a Nei’s genetic distance value of 0.22. The chickens of Bangalore rural and Mysore were least distant with a value of 0.056. The Ramanagara and Chamrajnagara pair had Nei’s genetic identity value of 0.802, which is least among all pairs of ecotypes. There were five main nodes from which the six ecotypes evolved on the basis 20 microsatellite markers used in this study. This study indicates that the four ecotypes Ramnagara, Bangalore Rural, Chickaballapura and Mysore are genetically identical due to their common ancestral evolution while, Mandya and Chamrajnagara ecotypes formed a relatively different cluster due to a separate common ancestral chicken population and less number of generations since drifting from bifurcation node. Conclusion: Twenty microsatellite markers based genetic diversity study on six indigenous ecotypes indicated lower genetic distances as well as lower FST values compared to the distinguished breeds reported. There were two main clusters, which differentiated into six ecotypes. They may differentiate into more distinct varieties if bred in

    Megan Marie Stronach

    2014-09-01

    Full Text Available Abstract: This article focuses on a philosophical approach employed in a PhD research project that set out to investigate sport career transition (SCT experiences of elite Indigenous Australian sportsmen. The research was necessary as little is known about the transition of this cohort to a life after sport, or their experiences of retirement. A key problem within the SCT paradigm is a presumption that an end to elite sport requires a process of adjustment that is common to all sportspeople—a rather narrow perspective that fails to acknowledge the situational complexity and socio-cultural diversity of elite athletes. With such a range of personal circumstances, it is reasonable to suppose that athletes from different cultural groups will have different individual SCT needs. The researcher is non-Indigenous and mature aged: she encountered a number of challenges in her efforts to understand Indigenous culture and its important sensitivities, and to build trust with the Indigenous male participants she interviewed. An Indigenous philosophy known as Dadirri, which emphasises deep and respectful listening, guided the development of the research design and methodology. Consistent with previous studies conducted by non-Indigenous researchers, an open-ended and conversational approach to interviewing Indigenous respondents was developed. The objective was for the voices of the athletes to be heard, allowing the collection of rich data based on the participants’ perspectives about SCT. An overview of the findings is presented, illustrating that Indigenous athletes experience SCT in complex and distinctive ways. The article provides a model for non-Indigenous researchers to conduct qualitative research with Indigenous people.

This prompted exploration of how its services might be improved. A resultant systematic search of the literature is reported in this article. Seven electronic databases and seven websites were systematically searched for peer reviewed and gray literature documenting responses to the sexual assault of Indigenous Australians. These publications were then classified by response type and study type. Twenty-three publications met the inclusion criteria. They included studies of legal justice, media, and community-based and mainstream service responses for Indigenous survivors and perpetrators. We located program descriptions, measurement, and descriptive research, but no intervention studies. There is currently insufficient evidence to confidently prescribe what works to effectively respond to Indigenous Australian sexual assault. The study revealed an urgent need for researchers, Indigenous communities, and services to work together to develop the evidence base.

    Indigenous Australians have higher levels of mental illness, self-harm, suicide and substance abuse than non-Indigenous Australians, as well as more frequent contact with the criminal justice system. These indices point to the need for strong leadership to support Close the Gap programmes that have now been implemented across Australia. This article considers leadership as a journey of learning for Australian Indigenous leaders. Through the use of story, it is suggested that a situational leadership approach, incorporating the principles of mindfulness, provides the most appropriate framework for Indigenous leaders who work with Indigenous communities. Flexible approaches are needed to meet the needs of diverse Indigenous populations, and address the complex challenges involved, including lateral violence. Such flexibility will enable Indigenous leaders and communities to work together to achieve improvements in the health outcomes, not only for Indigenous Australians, but also for Indigenous populations worldwide.

    Asthma education is regarded as an important step in the management of asthma in national guidelines. Racial, ethnicity and socio-economic factors are associated with markers of asthma severity, including recurrent acute presentations to emergency health facilities. Worldwide, indigenous groups are disproportionately represented in the severe end of the asthma spectrum. Appropriate models of care are important in the successful delivery of services, and are likely contributors to improved outcomes for people with asthma. To determine whether involvement of an indigenous healthcare worker (IHW) in comparison to absence of an IHW in asthma education programs, improves asthma related outcomes in indigenous children and adults with asthma. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE and EMBASE databases, review articles and reference lists of relevant articles. The latest search was in January 2010. All randomised controlled trials comparing involvement of an indigenous healthcare worker (IHW) in comparison to absence of an IHW in asthma education programs for indigenous people with asthma. Two independent review authors selected data for inclusion, a single author extracted the data. Both review authors independently assessed study quality. We contacted authors for further information. As it was not possible to analyse data as "intention-to-treat", we analysed data as "treatment received". Two studies fulfilled inclusion criteria involving 133 children randomised to an asthma education programme involving an IHW, compared to a similar education programme without an IHW. One study was not strictly Indigenous. 110 of these children completed the trials. Children's asthma knowledge score was significantly better in the group that had IHW education compared with control (mean difference 3.30; 95% CI 1.07 to 5.53), parents' asthma knowledge score (standardised mean difference (SMD) 1

    Historically, the goal of broadening participation in the geosciences has been expressed and approached from the viewpoint of the majority-dominated geoscience community. The need for more students who are American Indian, Native Hawaiian, or Alaska Native is expressed in terms of the need to diversify the research community, and strategies to engage more students are often posed around the question “what can we do to get more indigenous students interested in coming to our institutions to do geosciences?” This approach can lead to neglecting indigenous ways of knowing, inadvertently prioritizes western values over traditional ones, and doesn’t necessarily honor tribal community’s desire to hold on to their talented youth. Further, while this approach has resulted in some modest success, the overall participation in geoscience by students from indigenous backgrounds remains low. Many successful programs, however, have tried an alternate approach; they begin by approaching the geosciences from the viewpoint of indigenous communities. The questions they ask center around how geosciences can advance the priorities of indigenous communities, and their approaches focus on building capacity for the geosciences within indigenous communities. Most importantly, perhaps, these efforts originate in Tribal communities themselves, and invite the geoscience research community to partner in projects that are rooted in indigenous culture and values. Finally, these programs recognize that scientific expertise is only one among many skills indigenous peoples employ in their relation with their homelands. Climate change, like all things related to the landscape, is intimately connected to the core of indigenous cultures. Thus, emerging concerns about climate change provide a venue for developing new, indigenous-centered, approaches to the persistent problem of broadening participation in the geoscience. This presentation will highlight three indigenous-led efforts in to

    2015-12-01

    In order to examine the experiences of sexual harassment and sexual assault among indigenous and non-indigenous Mexican immigrant farmworkers in Oregon's Willamette Valley, a community-academic participatory research partnership initiated a study, which included focus groups, conducted and analyzed by skilled practitioners and researchers. The themes that emerged from the focus groups included direct and indirect effects of sexual harassment and sexual assault on women and risk factors associated with the farmworker workplace environment, and the increased vulnerability of non-Spanish-speaking indigenous women due to low social status, poverty, cultural and linguistic issues, and isolation. Recommendations for prevention and improved services for vulnerable women will be discussed as well as limitations and future research directions.

    High rates of obesity are a significant issue amongst Indigenous populations in many countries around the world. Media framing of issues can play a critical role in shaping public opinion and government policy. A broad range of media analyses have been conducted on various aspects of obesity, however media representation of Indigenous obesity remains unexplored. In this study we investigate how obesity in Australia's Indigenous population is represented in newsprint media coverage. Media articles published between 2007 and 2014 were analysed for the distribution and extent of coverage over time and across Indigenous and mainstream media sources using quantitative content analysis. Representation of the causes and solutions of Indigenous obesity and framing in text and image content was examined using qualitative framing analysis. Media coverage of Indigenous obesity was very limited with no clear trends in reporting over time or across sources. The single Indigenous media source was the second largest contributor to the media discourse of this issue. Structural causes/origins were most often cited and individual solutions were comparatively overrepresented. A range of frames were employed across the media sources. All images reinforced textual framing except for one article where the image depicted individual factors whereas the text referred to structural determinants. This study provides a starting point for an important area of research that needs further investigation. The findings highlight the importance of alternative news media outlets, such as The Koori Mail, and that these should be developed to enhance the quality and diversity of media coverage. Media organisations can actively contribute to improving Indigenous health through raising awareness, evidence-based balanced reporting, and development of closer ties with Indigenous health workers.

    Full Text Available By analyzing the forms and contents of the presentations made by indigenous performers and writers at the I Literary Party of Indigenous Poetics, this article exposes the challenges faced by traditional genre theories in tackling indigenous narratives and analyses how this “crisis” contributes to widening hierarchical and Western biased conceptions. On a stage open to contemporary indigenous expression, as is the literary party, the concepts of performance and storytelling, with the social function of maintaining tradition, continuous learning and transformation, better define this indigenous expression.

    Full Text Available Indigenous beers (chicha are part of the indigenous culture in Ecuador. The fermentation process of these beers probably relies on microorganisms from fermented substrates, environment and human microbiota. We analyzed the microbiota of artisanal beers (including a type of beer produced after chewing boiled cassava using bacterial culture and 16S ribosomal RNA (rRNA gene-based tag-encoded FLX amplicon pyrosequencing (bTEFAP. Surprisingly, we found that Streptococcus salivarius and Streptococcus mutans (part of the human oral microbiota were among the most abundant bacteria in chewed cassava and in non-chewed cassava beers. We also demonstrated that S. salivarius and S. mutans (isolated from these beers could proliferate in cassava mush. Lactobacillus sp. was predominantly present in most types of Ecuadorian chicha.

    Full Text Available Abstract Background Asthma is more common among Indigenous than non-Indigenous Australian adults, but little is known about socioeconomic patterning of asthma within the Indigenous population, or whether it is similar to the non-Indigenous population. Methods I analysed weighted data on self-reported current diagnosed asthma and a range of socio-economic and demographic measures for 5,417 Indigenous and 15,432 non-Indigenous adults aged 18-64 years from two nationally representative surveys conducted in parallel by the Australian Bureau of Statistics in 2004-05. Results Current asthma prevalence was higher for Indigenous than non-Indigenous people in every age group. After adjusting for age and sex, main language and place of residence were significantly associated with asthma prevalence in both populations. Traditional SES variables such as education, income and employment status were significantly associated with asthma in the non-Indigenous but not the Indigenous population. For example, age-and sex-adjusted relative odds of asthma among those who did not complete Year 10 (versus those who did was 1.2 (95% confidence interval (CI 1.0-1.5 in the non-Indigenous population versus 1.0 (95% CI 0.8-1.3 in the Indigenous population. Conclusions The socioeconomic patterning of asthma among Indigenous Australians is much less pronounced than for other chronic diseases such as diabetes and kidney disease, and contrasts with asthma patterns in the non-Indigenous population. This may be due in part to the episodic nature of asthma, and the well-known challenges in diagnosing it, especially among people with limited health literacy and/or limited access to health care, both of which are more likely in the Indigenous population. It may also reflect the importance of exposures occurring across the socioeconomic spectrum among Indigenous Australians, such as racism, and discrimination, marginalization and dispossession, chronic stress and exposure to

    Latin American women present more severe menopausal symptoms when compared to those from other regions of the world. Since this population is an ethnic blend of Caucasian and indigenous people, we sought to test the hypothesis that severe menopausal symptoms in Latin American women are associated with an indigenous origin. To assess menopausal symptoms among two specific indigenous Latin American populations. A total of 573 natural postmenopausal indigenous women aged 45-59 years (288 Quechua (Peru) and 285 Zenú (Colombia)) living in isolated communities were surveyed with a general questionnaire and the Menopause Rating Scale (MRS). The total MRS score was significantly higher among Quechua women as compared to Zenú ones (22.7 ± 5.7 vs. 14.7 ± 2.5, p Quechua women presented more intense somatic and psychological symptoms as compared to Zenú (8.8 ± 2.3 vs. 5.3 ± 1.8; and 7.8 ± 2.4 vs. 3.2 ± 1.7, p Quechua. This was not the case for Zenú women. More than 90% of indigenous women (Quechua and Zenú) at all age intervals presented severe urogenital scores, a percentage that is much higher than that described in the world literature. Severe menopausal symptoms found among Latin American women could be the result of their indigenous ethnic origin; the urogenital domain is the most affected.

    We compare the prevalence of suicidal thoughts and attempts between Indigenous and non-Indigenous males in urban and regional Australia, and examine the extent to which any disparity between Indigenous and non-Indigenous males varies across age groups. We used data from the baseline wave of The Australian Longitudinal Study on Male Health (Ten to Men), a large-scale cohort study of Australian males aged 10-55 years residing in urban and regional areas. Indigenous identification was determined through participants self-reporting as Aboriginal, Torres Strait Islander or both. The survey collected data on suicidal thoughts in the preceding 2 weeks and lifetime suicide attempts. A total of 432 participants (2.7%) identified as Indigenous and 15,425 as non-Indigenous (97.3%). Indigenous males were twice as likely as non-Indigenous males to report recent suicidal thoughts (17.6% vs 9.4%; odds ratio = 2.1, p age groups, but a significant gap emerged among men aged 30-39 years and was largest among men aged 40-55 years. Similarly, the prevalence of lifetime suicide attempts did not differ between Indigenous and non-Indigenous males in the 14- to 17-years age group, but a disparity emerged in the 18- to 24-years age group and was even larger among males aged 25 years and older. Our paper presents unique data on suicidal thoughts and attempts among a broad age range of Indigenous and non-Indigenous males. The disparity in the prevalence of suicidal thoughts increased across age groups, which is in contrast to the large disparity between the Indigenous and non-Indigenous suicide rates in younger age groups.

    Full Text Available In November 2014, the lead researcher’s interest in the conceptual development of digital technology and her cultural connection to Indigenous Knowledge Systems created an opportunity to explore a culturally relevant use of technology with urban Indigenous youth: the Indigenous Robotics Prototype Workshop. The workshop achieved a sense of cultural pride and confidence in Indigenous traditional knowledge while inspiring the youth to continue with their engagement in coding and programming through building robots. Yet, the outcomes from the prototype workshop further revealed a need to investigate how Indigenous Knowledge Systems, and particularly Pattern Thinking, might hint toward a possible paradigm shift for the ethical and advanced design of new technologies. This article examines the implications of such a hypothetical shift in autonomous systems in robotics and artificial intelligence (AI, using the Indigenous Robotics Prototype Workshop as a case study and springboard.

  3. Sporting Chance: Indigenous Participation in Australian Sport History

    2010-08-01

    Full Text Available For many non-Indigenous Australians the only time they have any engagement with Indigenous peoples, history or issues is through watching sport on television or being at a football match at the MCG. This general myopia and indifference by settler Australians with Indigenous Australians manifests itself in many ways but perhaps most obscenely in the simple fact that Indigenous Australians die nearly 20 years younger than the rest of Australias citizens. Many non-Indigenous Australians do not know this. Sport in many ways has offered Indigenous Australians a platform from which to begin the slow, hard process for social justice and equity to be actualised. This paper will discuss the participation of Indigenous Australians in sport and show how sport has enabled Indigenous Australians to create a space so that they can speak out against the injustices they have experienced and to further improve on relations going into the future. The central contention is that through sport all Australians can begin a process of engaging with Indigenous history as a means to improve race relations between the two groups.

    Arsenic is a known human carcinogen. Arsenite [As(III), H 3 AsO 3 ] and arsenate [As(V), H 2 AsO 4 - and HAsO 4 2- ] are the two predominant compounds of As found in surface water and groundwater. The aim of this study was to explore a bioremediation strategy for biotransformation of arsenite to arsenate by microorganisms. In this study, Babagorgor Spring, located west of Iran, was selected as the arsenic-contaminated source and its physicochemical characteristics and in situ microbiological composition were analyzed. Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) analysis indicated that the arsenic level was 614μg/l. Fourteen arsenic tolerant indigenous bacteria were isolated from arsenic-contaminated water using chemically defined medium (CDM), supplemented with 260-3900mg/l arsenite and 1560-21800mg/l arsenate. Among the isolates, a strain As-11 exhibited high ability of arsenic transformation. Biochemical tests were used for bacterial identification and confirmation was conducted by 16S rRNA sequence analysis. Results confirmed that As-11 was related to the genus Pseudomonas. This bacterium showed maximum tolerable concentration to arsenite up to 3250mg/l and arsenate up to 20280mg/l. Under heterotrophic conditions, the bacterium exhibited 48% of As(III) and 78% of As(V) transformation from the medium amended with 130 and 312mg/l of sodium arsenite and sodium arsenate, respectively. Moreover, under chemolithotrophic conditions, bacterium was able to transform 41% of 130mg/l of As(III) from the medium amended with nitrate as the terminal electron acceptor. Pseudomonas strain As-11 was reported as an arsenic transformer, for the first time. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available A produção e consumo de alimentos industrializados têm aumentado a preocupação com suplementação e enriquecimento de alimentos com vitaminas e sais minerais, visando repor as possíveis perdas durante os processos de fabricação, principalmente das vitaminas hidrossolúveis, mais especificamente da vitamina B2 ou riboflavina. Assim sendo, a proposta deste trabalho foi utilizar como componente principal do meio, para produção da riboflavina, um subproduto do refino de óleos vegetais e o microrganismo Candida guillermondii DM 644. A produção da vitamina B2 foi realizada por fermentação em batelada utilizando Erlenmeyer. As condições empregadas foram agitação orbital, ausência de luz, 30°C, e 24h de incubação. A otimização da produção de riboflavina foi realizada através de Delineamento Fatorial Fracionário, para avaliar os efeitos da concentração de matéria graxa, fonte de nitrogênio, pH, velocidade de agitação, fonte de fósforo e extrato de levedura e as possíveis interações. A concentração máxima de riboflavina foi 19,12mg/mL. Os fatores mais importantes para produção de riboflavina foram a concentração de matéria graxa e a fonte de nitrogênio, enquanto que a fonte de fósforo e o extrato de leveduras não estimularam sua biossíntese. A máxima produção foi obtida com matéria graxa a 10g/L, uréia a 2,5g/L e pH 5,0. A velocidade de agitação (200 e 400rpm não interferiu no processo biotecnológico.The ever growing production and consumption of industrialized foods have increased the concern about supplementation and enrichment of food with vitamins and minerals, attempting the replenishment of the possible losses during their production processes, mainly the hydrosoluble vitamins, more specifically B2 vitamin or riboflavin.

    Little is known about the impact of comorbidity on cervical cancer survival in Australian women, including whether Indigenous women's higher prevalence of comorbidity contributes to their lower survival compared to non-Indigenous women. Data for cervical cancers diagnosed in 2003-2012 were extracted from six Australian state-based cancer registries and linked to hospital inpatient records to identify comorbidity diagnoses. Five-year cause-specific and all-cause survival probabilities were estimated using the Kaplan-Meier method. Flexible parametric models were used to estimate excess cause-specific mortality by Charlson comorbidity index score (0,1,2+), for Indigenous women compared to non-Indigenous women. Of 4,467 women, Indigenous women (4.4%) compared to non-Indigenous women had more comorbidity at diagnosis (score ≥1: 24.2% vs. 10.0%) and lower five-year cause-specific survival (60.2% vs. 76.6%). Comorbidity was associated with increased cervical cancer mortality for non-Indigenous women, but there was no evidence of such a relationship for Indigenous women. There was an 18% reduction in the Indigenous: non-Indigenous hazard ratio (excess mortality) when comorbidity was included in the model, yet this reduction was not statistically significant. The excess mortality for Indigenous women was only evident among those without comorbidity (Indigenous: non-Indigenous HR 2.5, 95%CI 1.9-3.4), indicating that factors other than those measured in this study are contributing to the differential. In a subgroup of New South Wales women, comorbidity was associated with advanced-stage cancer, which in turn was associated with elevated cervical cancer mortality. Survival was lowest for women with comorbidity. However, there wasn't a clear comorbidity-survival gradient for Indigenous women. Further investigation of potential drivers of the cervical cancer survival differentials is warranted. The results highlight the need for cancer care guidelines and multidisciplinary

    2008-12-01

    Injury prevention in Indigenous communities in Australia is a continuing national challenge, with Indigenous fatality rates due to injury three times higher than the general population. Suicide and transport are the leading causes of injury mortality, and assault, transport and falls the primary causes of injury morbidity. Addressing the complex range of injury problems in disadvantaged Indigenous communities requires considerable work in building or enhancing existing capacity of communities to address local safety issues. Poor data, lack of funding and absence of targeted programs are some of the issues that impede injury prevention activities. Traditional approaches to injury prevention can be used to highlight key areas of need, however adaptations are needed in keeping with Indigenous peoples' holistic approach to health, linked to land and linked to community in order to address the complex spiritual, emotional and social determinants of Indigenous injury.

    This research program is directed at improving the knowledge of reservoir ecology and developing practical microbial solutions for improving oil production. The goal is to identify indigenous microbial populations which can produce beneficial metabolic products and develop a methodology to stimulate those select microbes with nutrient amendments to increase oil recovery. This microbial technology has the capability of producing multiple oil-releasing agents. Experimental laboratory work is underway. Microbial cultures have been isolated from produced water samples. Comparative laboratory studies demonstrating in situ production of microbial products as oil recovery agents were conducted in sand packs with natural field waters with cultures and conditions representative of oil reservoirs. Field pilot studies are underway.

    Saccharomyces and non-Saccharomyces yeast species from a winery located in Brazil were identified by ribosomal gene-sequencing analysis. A total of 130 yeast strains were isolated from grape surfaces and musts during alcoholic fermentation from Isabel, Bordeaux, and Cabernet Sauvignon varieties. Samples were submitted to PCR-RFLP analysis and genomic sequencing. Thirteen species were identified: Candida quercitrusa, Candida stellata, Cryptococcus flavescens, Cryptococcus laurentii, Hanseniaspora uvarum, Issatchenkia occidentalis, Issatchenkia orientalis, Issatchenkia terricola, Pichia kluyveri, Pichia guilliermondii, Pichia sp., Saccharomyces cerevisiae, and Sporidiobolus pararoseus. A sequential substitution of species during the different stages of fermentation, with a dominance of non-Saccharomyces yeasts at the beginning, and a successive replacement of species by S. cerevisiae strains at the final steps were observed. This is the first report about the yeast distribution present throughout the alcoholic fermentation in a Brazilian winery, providing supportive information for future studies on their contribution to wine quality.

    Full Text Available OBJECTIVE: Assess the epidemiological aspects of tuberculosis in Brazilian indigenous children and actions to control it. METHODS: An epidemiological study was performed with 356 children from 0 to 14 years of age in Rondônia State, Amazon, Brazil, during the period 1997-2006. Cases of TB reported to the Notifiable Diseases Surveillance System were divided into indigenous and non-indigenous categories and analyzed according to sex, age group, place of residence, clinical form, diagnostic tests and treatment outcome. A descriptive analysis of cases and hypothesis test (χ² was carried out to verify if there were differences in the proportions of illness between the groups investigated. RESULTS: A total of 356 TB cases were identified (125 indigenous, 231 non-indigenous of which 51.4% of the cases were in males. In the indigenous group, 60.8% of the cases presented in children aged 0-4 years old. The incidence mean was much higher among indigenous; in 2001, 1,047.9 cases/100,000 inhabitants were reported in children aged < 5 years. Pulmonary TB was reported in more than 80% of the cases, and in both groups over 70% of the cases were cured. Cultures and histopathological exams were performed on only 10% of the patients. There were 3 cases of TB/HIV co-infection in the non-indigenous group and none in the indigenous group. The case detection rate was classified as insufficient or fair in more than 80% of the indigenous population notifications, revealing that most of the diagnoses were performed based on chest x-ray. CONCLUSIONS: The approach used in this study proved useful in demonstrating inequalities in health between indigenous and non-indigenous populations and was superior to the conventional analyses performed by the surveillance services, drawing attention to the need to improve childhood TB diagnosis among the indigenous population.

    In order to examine the experiences of sexual harassment and sexual assault among indigenous and non-indigenous Mexican immigrant farmworkers in Oregon's Willamette Valley, a community-academic participatory research partnership initiated a study, which included focus groups, conducted and analyzed by skilled practitioners and researchers. The themes that emerged from the focus groups included direct and indirect effects of sexual harassment and sexual assault on women and risk factors associated with the farmworker workplace environment, and the increased vulnerability of non-Spanish-speaking indigenous women due to low social status, poverty, cultural and linguistic issues, and isolation. Recommendations for prevention and improved services for vulnerable women will be discussed as well as limitations and future research directions. PMID:24514945

    To examine differences in land use and environmental impacts between colonist and indigenous populations in the northern Ecuadorian Amazon, we combined data from household surveys and remotely sensed imagery that was collected from 778 colonist households in 64 colonization sectors, and 499 households from five indigenous groups in 36 communities. Overall, measures of deforestation and forest fragmentation were significantly greater for colonists than indigenous peoples. On average, colonist households had approximately double the area in agriculture and cash crops and 5.5 times the area in pasture as indigenous households. Nevertheless, substantial variation in land-use patterns existed among the five indigenous groups in measures such as cattle ownership and use of hired agricultural labor. These findings support the potential conservation value of indigenous lands while cautioning against uniform policies that homogenize indigenous ethnic groups.

    This preliminary ethnographic investigation focused on how Indigenous traditional wisdom can be incorporated into school science and what students learned as a result. Participants included community elders and knowledge keepers, as well as 4th grade (10-year-old) students, all of Amis ancestry, an Indigenous tribe in Taiwan. The students' non-Indigenous teacher played a central role in developing a science module `Measuring Time' that combined Amis knowledge and Western science knowledge. The study identified two cultural worldview perspectives on time; for example, the place-based cyclical time held by the Amis, and the universal rectilinear time presupposed by scientists. Students' pre-instructional fragmented concepts from both knowledge systems became more informed and refined through their engagement in `Measuring Time'. Students' increased interest and pride in their Amis culture were noted.

    2017-06-01

    This paper identifies the principal concerns of indigenous peoples with regard to current international treaties on certain psychoactive substances and policies to control and eradicate their production, trafficking, and sale. Indigenous peoples have a specific interest in the issue since their traditional lands have become integrated over time into the large-scale production of coca, opium poppy, and cannabis crops, in response to high demand from the American and European markets, among others. As a consequence, indigenous peoples are persecuted because of their traditional use of these and other plant-based narcotics and hallucinogens. They are also victims of the drug producers who remove them from their lands or forcibly recruit them into the production process. As indigenous peoples are caught in the violent world of illicit drug production, law enforcement often targets them first, resulting in disproportionate rates of criminalization and incarceration.

    Full Text Available Objective. We investigated the use of miconazole among female prostitutes in Costa Rica as well as the distribution of vaginal yeasts and the susceptibility pattern to azoles of strains obtained from this population. Our intention was to relate a frequent use of miconazole to occurrence of vaginal yeasts resistant to azoles. Methods. Vaginal samples were taken from 277 patients that have previously used azoles. Vaginal swabs were obtained for direct microscopy and culture. Yeast isolates were identified by germ tube test and assimilation pattern. Susceptibility testing was determined using a tablet diffusion method. Results. The number of clinical Candida isolates (one from each patient was 57 (20.6%. C. albicans was the predominant species (70%, followed by C. parapsilosis (12%, C. tropicalis (5.3%, C. glabrata and C. famata (3.5% each, C. krusei, C. inconspicua and C. guilliermondii (1.7% each. The majority of vaginal Candida isolates were susceptible to ketoconazole (91%, fluconazole (96.5%, and itraconazole (98%. A lower susceptibility of some isolates to miconazole (63% was observed as compared to the other azoles tested. Moreover, the strains, nonsusceptible to miconazole, were more often obtained from patients that have used this antifungal at least four times within the last year before taking the samples as compared to those with three or less treatments (P<.01. Conclusion. An indiscriminate use of miconazole, such as that observed among female prostitutes in Costa Rica, results in a reduced susceptibility of vaginal yeasts to miconazole but not to other azoles.

    2012-01-01

    The role of indigenous and non-indigenous arbuscular mycorrhizal fungi (AMF) on As uptake by Plantago lanceolata L. growing on substrate originating from mine waste rich in As was assessed in a pot experiment. P. lanceolata inoculated with AMF had higher shoot and root biomass and lower concentrations of As in roots than the non-inoculated plants. There were significant differences in As concentration and uptake between different AMF isolates. Inoculation with the indigenous isolate resulted in increased transfer of As from roots to shoots; AMF from non-polluted area apparently restricted plants from absorbing As to the tissue; and plants inoculated with an AMF isolate from Zn–Pb waste showed strong As retainment within the roots. Staining with dithizone indicated that AMF might be actively involved in As accumulation. The mycorrhizal colonization affected also the concentration of Cd and Zn in roots and Pb concentration, both in shoots and roots. - Highlights: ► The role of arbuscular mycorrhizal fungi (AMF) in As uptake was studied. ► Growth of Plantago lanceolata was significantly enhanced by mycorrhizal inoculation. ► Arsenic concentration and uptake significantly depended on the AMF isolate. ► Arbuscular mycorrhizal fungi may be useful for bioremediation of As contaminated wastes. - Effect of arbuscular mycorrhizal fungi on As uptake by Plantago lanceolata strongly depends on the origin of fungal isolates.

    2016-12-01

    Full Text Available Most part of indigenous adults in the Guarani communities of Mato Grosso do Sul is bilingual and has one of the indigenous languages, Guarani Kaiowá or Guarani Ñandeva, as their mother tongue and Portuguese as a second language; only a few elderly and young children still who do not go to school speak only the mother tongue. In this paper, we try to verify which impression the speakers have for each of these languages and the importance they attribute to each one of them. Data analysis showed that the mother tongue is closely related to the expression of their traditional culture; in general, the indigenous claim their languages are being transmitted to new generations, and therefore preserved in an appropriate manner in the two communities. The Portuguese is also considered very important by all informants and the main motivation for its teaching/learning is the need to contact with the non-indigenous population. These results may help us understand issues related to the future of these indigenous languages and Portuguese language in the investigated communities.

    Rates of chronic kidney disease (CKD) among Indigenous groups in Australia exceed non-Indigenous rates eight-fold. Using kidney volume as a surrogate for nephron number, we carried out a study to determine if Indigenous neonates have a smaller kidney volume (and thus a reduced nephron number) from birth compared with non-Indigenous neonates. We recruited term and preterm neonates (Indigenous) and 39 term (13 Indigenous) neonates. TKV of Indigenous neonates was significantly lower at 32 weeks [12.0 (2.0) v. 15.4 (5.1) ml; P=0.03] and 38 weeks CA [18.6 (4.0) v. 22.6 (5.9) ml; P=0.04] respectively. Term Indigenous neonates also had smaller kidney volumes compared with non-Indigenous neonates. Despite a smaller kidney volume (and reduced nephron number), Indigenous neonates did not have a significantly lower eGFR. Indigenous neonates achieve similar eGFRs to Non-Indigenous neonates, presumably through a higher single nephron filtration rate. This places Indigenous neonates at a greater risk of long-term kidney damage later in life.

    The indigenous fungal species populating cereal grains produce numerous plant cell wall-degrading enzymes including xylanases, which could play important role in plant-pathogen interactions and in adaptation of the fungi to varying carbon sources. To gain more insight into the grain surface......-associated enzyme activity, members of the populating fungal community were isolated, and their secretomes and xylanolytic activities assessed. Twenty-seven different fungal species were isolated from grains of six barley cultivars over different harvest years and growing sites. The isolated fungi were grown...... on medium containing barley flour or wheat arabinoxylan as sole carbon source. Their secretomes and xylanase activities were analyzed using SDS-PAGE and enzyme assays and were found to vary according to species and carbon source.

    Though Indigenous Australian peoples reportedly have poorer survival outcome after cardiac surgery, few studies have jointly documented the experience of major morbidity, and considered the influence of patient geographic remoteness. From January 1998 to September 2008, major morbidity events and survival were recorded for 2748 consecutive patients undergoing coronary artery bypass graft surgery. Morbidity and survival analyses adjusted for propensity deciles based on patient ethnicity and age, sex, left ventricular ejection fraction, recent myocardial infarction, tobacco smoking, diabetes, renal disease and history of stroke. Sensitivity analyses controlled for the patient accessibility/remoteness index of Australia (ARIA). The 297 Indigenous Australian patients (10.8% of total) had greater odds for total morbidity (adjusted odds ratio = 1.55; 95% confidence interval [CI] 1.04-2.30) and prolonged ventilation (adjusted odds ratio = 2.08; 95% confidence interval [CI] 1.25-3.44) in analyses adjusted for propensity deciles and geographic remoteness. With a median follow-up of 7.5 years (interquartile range 5.2-10.2), Indigenous Australian patients were found to experience 30% greater mortality risk (unadjusted hazard ratio = 1.30; 95% CI: 1.03-1.64, p = 0.03). The effect size strengthened after adjustment for propensity score (adjusted hazard ratio = 1.49; 95% CI: 1.13-1.96, p = .004). Adjustment for ARIA categorisation strengthened the effect size (adjusted HR = 1.54 (95% CI: 1.11-2.13, p = .009). Indigenous Australian peoples were at greater risk for prolonged ventilation and combined morbidity outcome, and experienced poorer survival in the longer term. Higher mortality risk among Indigenous Australians was evident even after controlling for remoteness and accessibility to services. Crown Copyright © 2013. Published by Elsevier B.V.

  16. African Indigenous science in higher education in Uganda

    Akena Adyanga, Francis

    This study examines African Indigenous Science (AIS) in higher education in Uganda. To achieve this, I use anticolonial theory and Indigenous knowledge discursive frameworks to situate the subjugation of Indigenous science from the education system within a colonial historical context. These theories allow for a critical examination of the intersection of power relations rooted in the politics of knowledge production, validation, and dissemination, and how this process has become a systemic and complex method of subjugating one knowledge system over the other. I also employ qualitative and autoethnographic research methodologies. Using a qualitative research method, I interviewed 10 students and 10 professors from two universities in Uganda. My research was guided by the following key questions: What is African Indigenous Science? What methodology would help us to indigenize science education in Uganda? How can we work with Indigenous knowledge and anticolonial theoretical discursive frameworks to understand and challenge the dominance of Eurocentric knowledge in mainstream education? My research findings revealed that AIS can be defined in multiple ways, in other words, there is no universal definition of AIS. However, there were some common elements that my participants talked about such as: (a) knowledge by Indigenous communities developed over a long period of time through a trial and error approach to respond to the social, economic and political challenges of their society. The science practices are generational and synergistic with other disciplines such as history, spirituality, sociology, anthropology, geography, and trade among others, (b) a cumulative practice of the use, interactions with and of biotic and abiotic organism in everyday life for the continued existence of a community in its' totality. The research findings also indicate that Indigenous science is largely lacking from Uganda's education curriculum because of the influence of colonial and

    Indigenous data governance principles assert that Indigenous communities have a right to data that identifies their people or communities, and a right to determine the use of that data in ways that support Indigenous health and self-determination. Indigenous-driven use of the databases held at the Institute for Clinical Evaluative Sciences (ICES) has resulted in ongoing partnerships between ICES and diverse Indigenous organizations and communities. To respond to this emerging and complex landscape, ICES has established a team whose goal is to support the infrastructure for responding to community-initiated research priorities.

    Full Text Available It has previously been shown that being of aboriginal descent is a risk factor for hamstring injuries in Australian football. The aim of this study was to review the Australian Football League (AFL injury database to determine whether there were any injuries where indigenous players had different relative risks to non-indigenous players. Analysis was conducted using data from the AFL injury database, which included data from 4,492 players over 21 years (1992–2012, covering 162,683 player-matches at AFL level, 91,098 matches at lower levels and 328,181 weeks (possible matches of exposure. Compared to non-indigenous players, indigenous players had a significantly higher risk of hamstring injuries (RR 1.52, 95% CI 1.32–1.73 and calf strains (RR 1.30, 95% CI 1.00–1.69. Conversely, indigenous players had a significantly lower risk of lumbar/thoracic spine injuries (RR 0.61, 95% CI 0.41–0.91, groin strains/osteitis pubis (RR 0.75, 95% CI 0.58–0.96 and Achilles tendon injuries (RR 0.32, 95% CI 0.12–0.86. The results for the above injuries were also significant in terms of games missed. There was no difference between overall risk of injury (RR 1.03, 95% CI 0.96–1.10 or missed games (RR 1.00, 95% CI 0.97–1.04. This suggests that indigenous AFL players have the same overall number of injuries and missed games, but a slightly different injury profile.

    Limited understanding of Indigenous adults' cardiovascular structure and function exists despite high rates of cardiovascular disease. This investigation characterised cardiovascular structure and function among young Indigenous adults and compared to age- and sex-matched European descendants. Echocardiographic assessments included apical two- and four-chamber images, parasternal short-axis images and Doppler. Analyses included cardiac volumes, dimensions, velocities and strains. Cardiovascular structure and function were similar between Indigenous (n=10, 25 ± 3 years, 4 women) and European-descendant (n=10, 24 ± 4 years, 4 women,) adults, though European descendants demonstrated greater systemic vascular resistance (18.19 ± 3.94 mmHg∙min -1 ∙L -1 vs. 15.36 ± 2.97 mmHg∙min -1 ∙L -1 , p=0.03). Among Indigenous adults, women demonstrated greater arterial elastance (0.80 ± 0.15 mmHg·mL -1 ·m -2 vs. 0.55 ± 0.17 mmHg·mL -1 ·m -2 , p=0.02) and possibly greater systemic vascular resistance (17.51 ± 2.20 mmHg∙min -1 ∙L -1 vs. 13.93 ± 2.61 mmHg∙min -1 ∙L -1 , p=0.07). Indigenous men had greater cardiac size, dimensions and output, though body size differences accounted for cardiac size differences. Similar cardiac rotation and strains were observed across sexes. Arterial elastance and cardiac size were different between Indigenous men and women while cardiovascular structure and function may be similar between Indigenous and European descendants.

    2012-06-01

    Full Text Available This article examines the Venezuelan regional elections of 2008 as a contextual event for the analysis of electoral strategies and results associated with the indigenous representation. Three factors intertwined in the electoral moment are analyzed: 1. the existence of minimum guaranteed representation for indigenous population in legislative organs; 2. the participation of indigenous candidates and electors; 3. the maneuvers of political parties and civil organizations that attempt to channel and/or benefit from such indigenous representation and participation. The description of the electoral context facilitates the identification of factors that, beyond the normative structure of the State, condition the agency of individuals and parties involved in electoral processes. Among those factors are the symbolic value of indigeneity in the current process of national identity re-definition, the interest of political parties in controlling the vote of the indigenous representation and the tendency towards the consolidation of professionalized elites within the indigenous activism.

    Full Text Available Abstract Background Indigenous fermented food products play an essential role in the diet of millions of Africans. Lactic acid bacteria (LAB are among the predominant microbial species in African indigenous fermented food products and are used for different applications in the food and biotechnology industries. Numerous studies have described antimicrobial susceptibility profiles of LAB from different parts of the world. However, there is limited information on antimicrobial resistance profiles of LAB from Africa. The aim of this study was to characterize 33 LAB previously isolated from three different African indigenous fermented food products using (GTG5-based rep-PCR, sequencing of the 16S rRNA gene and species-specific PCR techniques for differentiation of closely related species and further evaluate their antibiotic resistance profiles by the broth microdilution method and their haemolytic activity on sheep blood agar plates as indicators of safety traits among these bacteria. Results Using molecular biology based methods and selected phenotypic tests such as catalase reaction, CO2 production from glucose, colonies and cells morphology, the isolates were identified as Lactobacillus delbrueckii, Lactobacillus fermentum, Lactobacillus ghanensis, Lactobacillus plantarum, Lactobacillus salivarius, Leuconostoc pseudomesenteroides, Pediococcus acidilactici, Pediococcus pentosaceus and Weissella confusa. The bacteria were susceptible to ampicillin, chloramphenicol, clindamycin and erythromycin but resistant to vancomycin, kanamycin and streptomycin. Variable sensitivity profiles to tetracycline and gentamicin was observed among the isolates with Lb. plantarum, Lb. salivarius, W. confusa (except strain SK9-5 and Lb. fermentum strains being susceptible to tetracycline whereas Pediococcus strains and Lb. ghanensis strains were resistant. For gentamicin, Leuc. pseudomesenteroides, Lb. ghanensis and Ped. acidilactici strains were resistant to 64

    In recent years, Thai indigenous chickens have increasingly been bred as an alternative in Thailand poultry market. Due to their popularity, there is a clear need to improve the underlying quality and productivity of these chickens. Studying chicken genetic variation can improve the chicken meat quality as well as conserving rare chicken species. To begin with, a minimal set of molecular markers that can characterize the Thai indigenous chicken breeds is required. Using AFLP-PCR, 30 single nucleotide polymorphisms (SNPs) from Thai indigenous chickens were obtained by DNA sequencing. From these SNPs, we genotyped 465 chickens from 7 chicken breeds, comprising four Thai indigenous chicken breeds--Pradhuhangdum (PD), Luenghangkhao (LK), Dang (DA) and Chee (CH), one wild chicken--the red jungle fowls (RJF), and two commercial chicken breeds--the brown egg layer (BL) and commercial broiler (CB). The chicken genotypes reveal unique genetic structures of the four Thai indigenous chicken breeds. The average expected heterozygosities of PD=0.341, LK=0.357, DA=0.349 and CH=0.373, while the references RJF= 0.327, CB=0.324 and BL= 0.285. The F(ST) values among Thai indigenous chicken breeds vary from 0.051 to 0.096. The F(ST) values between the pairs of Thai indigenous chickens and RJF vary from 0.083 to 0.105 and the FST values between the Thai indigenous chickens and the two commercial chicken breeds vary from 0.116 to 0.221. A neighbour-joining tree of all individual chickens showed that the Thai indigenous chickens were clustered into four groups which were closely related to the wild RJF but far from the commercial breeds. Such commercial breeds were split into two closely groups. Using genetic admixture analysis, we observed that the Thai indigenous chicken breeds are likely to share common ancestors with the RJF, while both commercial chicken breeds share the same admixture pattern. These results indicated that the Thai indigenous chicken breeds may descend from the

    In this article, I explore the relationship between housing, home and health amongst Indigenous homeless people living in the Canadian North. In particular, I examine the ways in which Indigenous homemaking practices conflict with housing policy, and exacerbate individual pathways to homelessness....... I argue that integral components in northern Indigenous conceptualizations of home and, in turn, health are not only unrecognized in housing policy, but actively discouraged. The potential for homemaking to inform health and housing policy speaks to the relevance of cultural safety not only...... to Indigenous health services, but also to a comprehensive framing of Indigenous health....

    2010-01-01

    Indigenous peoples often have the worst health status in comparison to non-indigenous people in their own nations; urgent action to address the health inequities for indigenous people is required. The role of rehabilitation in addressing health and disability inequities is particularly important due to the health need of indigenous peoples; the unequal distribution of health determinants; and disparities in access to, quality of care through and outcomes following rehabilitation. This article will present a perspective for Māori, the indigenous peoples of New Zealand, on a framework for improving rehabilitation services for Māori and ultimately their health and wellbeing.

  11. Sugarcane straw as a feedstock for xylitol production by Candida guilliermondii FTI 20037.

    Sugarcane straw has become an available lignocellulosic biomass since the progressive introduction of the non-burning harvest in Brazil. Besides keeping this biomass in the field, it can be used as a feedstock in thermochemical or biochemical conversion processes. This makes feasible its incorporation in a biorefinery, whose economic profitability could be supported by integrated production of low-value biofuels and high-value chemicals, e.g., xylitol, which has important industrial and clinical applications. Herein, biotechnological production of xylitol is presented as a possible route for the valorization of sugarcane straw and its incorporation in a biorefinery. Nutritional supplementation of the sugarcane straw hemicellulosic hydrolyzate as a function of initial oxygen availability was studied in batch fermentation of Candida guilliermondii FTI 20037. The nutritional supplementation conditions evaluated were: no supplementation; supplementation with (NH4)2SO4, and full supplementation with (NH4)2SO4, rice bran extract and CaCl2·2H2O. Experiments were performed at pH 5.5, 30°C, 200rpm, for 48h in 125mL Erlenmeyer flasks containing either 25 or 50mL of medium in order to vary initial oxygen availability. Without supplementation, complete consumption of glucose and partial consumption of xylose were observed. In this condition the maximum xylitol yield (0.67gg(-1)) was obtained under reduced initial oxygen availability. Nutritional supplementation increased xylose consumption and xylitol production by up to 200% and 240%, respectively. The maximum xylitol volumetric productivity (0.34gL(-1)h(-1)) was reached at full supplementation and increased initial oxygen availability. The results demonstrated a combined effect of nutritional supplementation and initial oxygen availability on xylitol production from sugarcane straw hemicellulosic hydrolyzate.

    Full Text Available It is acknowledged that health outcomes for Australian Indigenous peoples are lower than those of non-Indigenous Australians. Research suggests negative media in relation to Indigenous Australians perpetuates racist stereotypes among the wider population and impacts on the health of Indigenous Australians. This study examined the media portrayal of Indigenous Australian public health issues in selected media over a twelve month period and found that, overwhelmingly, the articles were negative in their portrayal of Indigenous health. A total of 74 percent of the coverage of Australian Indigenous related articles were negative, 15 percent were positive, and 11 percent were neutral. The most common negative subject descriptors related to alcohol, child abuse, petrol sniffing, violence, suicide, deaths in custody, and crime.

    The health gap between Indigenous and non-Indigenous Australians may be exacerbated by climate change if temperature extremes have disproportionate adverse effects on Indigenous people. To explore this issue, we analysed the effect of temperature extremes on hospital admissions for respiratory diseases, stratified by age, Indigenous status and sex, for people living in two different climates zones in the Northern Territory during the period 1993–2011. We examined admissions for both acute and chronic respiratory diagnoses, controlling for day of the week and seasonality variables. Our analysis showed that: (1) overall, Indigenous hospital admission rates far exceeded non-Indigenous admission rates for acute and chronic diagnoses, and Top End climate zone admission rates exceeded Central Australia climate zone admission rates; (2) extreme cold and hot temperatures were associated with inconsistent changes in admission rates for acute respiratory disease in Indigenous and non-Indigenous children and older adults; and (3) no response to cold or hot temperature extremes was found for chronic respiratory diagnoses. These findings support our two hypotheses, that extreme hot and cold temperatures have a different effect on hospitalisations for respiratory disease between Indigenous and non-Indigenous people, and that these health risks vary between the different climate zones. We did not, however, find that there were differing responses to temperature extremes in the two populations, suggesting that any increased vulnerability to climate change in the Indigenous population of the Northern Territory arises from an increased underlying risk to respiratory disease and an already greater existing health burden.

    Cowpea (Vigna unguiculata) is a promiscuous grain legume, capable of establishing efficient symbiosis with diverse symbiotic bacteria, mainly slow-growing rhizobial species belonging to the genus Bradyrhizobium. Although much research has been done on cowpea-nodulating bacteria in various countries around the world, little is known about the genetic and symbiotic diversity of indigenous cowpea rhizobia in European soils. In the present study, the genetic and symbiotic diversity of indigenous rhizobia isolated from field-grown cowpea nodules in three geographically different Greek regions were studied. Forty-five authenticated strains were subjected to a polyphasic approach. ERIC-PCR based fingerprinting analysis grouped the isolates into seven groups and representative strains of each group were further analyzed. The analysis of the rrs gene showed that the strains belong to different species of the genus Bradyrhizobium. The analysis of the 16S-23S IGS region showed that the strains from each geographic region were characterized by distinct IGS types which may represent novel phylogenetic lineages, closely related to the type species of Bradyrhizobium pachyrhizi, Bradyrhizobium ferriligni and Bradyrhizobium liaoningense. MLSA analysis of three housekeeping genes (recA, glnII, and gyrB) showed the close relatedness of our strains with B. pachyrhizi PAC48 T and B. liaoningense USDA 3622 T and confirmed that the B. liaoningense-related isolate VUEP21 may constitute a novel species within Bradyrhizobium. Moreover, symbiotic gene phylogenies, based on nodC and nifH genes, showed that the B. pachyrhizi-related isolates belonged to symbiovar vignae, whereas the B. liaoningense-related isolates may represent a novel symbiovar.

    The traditional use of medicinal plants for treatment of infectious diseases by an indigenous Mbyá-Guarani tribe from South Brazil was assessed by evaluating the antibiotic and antibiofilm activities against relevant bacterial pathogens. Aqueous extracts from 10 medicinal plants were prepared according to indigenous Mbyá-Guarani traditional uses. To evaluate antibiotic (OD600) and antibiofilm (crystal violet method) activities, Pseudomonas aeruginosa ATCC 27853, Staphylococcus epidermidis ATCC 35984 and seven multi-drug resistant Klebsiella pneumoniae carbapenemase (KPC)-producing bacterial clinical isolates were challenged with the extracts. Furthermore, the susceptibility profile of KPC-producing bacteria and the ability of these isolates to form biofilm were evaluated. The plants Campomanesia xanthocarpa, Maytenus ilicifolia, Bidens pilosa and Verbena sp. showed the best activity against bacterial growth and biofilm formation. The majority of KPC-producing isolates, which showed strong ability to form biofilm and a multidrug resistance profile, was inhibited by more than 50% by some extracts. The Enterobacter cloacae (KPC 05) clinical isolate was the only one resistant to all extracts. This study confirms the importance of indigenous traditional medicinal knowledge and describes for the first time the ability of these plants to inhibit biofilm formation and/or bacterial growth of multi-drug resistant KPC-producing isolates.

    The organizers of the 2014 US National Climate Assessment (NCA) made a concerted effort to reach out to and collaborate with Indigenous peoples, resulting in the most comprehensive information to date on climate change impacts to Indigenous peoples in a US national assessment. Yet, there is still much room for improvement in assessment processes to ensure adequate recognition of Indigenous perspectives and Indigenous knowledge systems. This article discusses the process used in creating the Indigenous Peoples, Land, and Resources NCA chapter by a team comprised of tribal members, agencies, academics, and non-governmental organizations, who worked together to solicit, collect, and synthesize traditional knowledges and data from a diverse array of Indigenous communities across the US. It also discusses the synergy and discord between traditional knowledge systems and science and the emergence of cross-cutting issues and vulnerabilities for Indigenous peoples. The challenges of coalescing information about climate change and its impacts on Indigenous communities are outlined along with recommendations on the types of information to include in future assessment outputs. We recommend that future assessments – not only NCA, but other relevant local, regional, national, and international efforts aimed at the translation of climate information and assessments into meaningful actions – should support integration of Indigenous perspectives in a sustained way that builds respectful relationships and effectively engages Indigenous communities. Given the large number of tribes in the US and the current challenges and unique vulnerabilities of Indigenous communities, a special report focusing solely on climate change and Indigenous peoples is warranted.This article is part of a special issue on “The National Climate Assessment: Innovations in Science and Engagement” edited by Katharine Jacobs, Susanne Moser, and James Buizer.

  7. Indigenous Knowledge and Sea Ice Science: What Can We Learn from Indigenous Ice Users?

    Eicken, H.

    2010-12-01

    Drawing on examples mostly from Iñupiaq and Yup’ik sea-ice expertise in coastal Alaska, this contribution examines how local, indigenous knowledge (LIK) can inform and guide geophysical and biological sea-ice research. Part of the relevance of LIK derives from its linkage to sea-ice use and the services coastal communities derive from the ice cover. As a result, indigenous experts keep track of a broad range of sea-ice variables at a particular location. These observations are embedded into a broader worldview that speaks to both long-term variability or change and to the system of values associated with ice use. The contribution examines eight different contexts in which LIK in study site selection and assessment of a sampling campaign in the context of inter annual variability, the identification of rare or inconspicuous phenomena or events, the contribution by indigenous experts to hazard assessment and emergency response, the record of past and present climate embedded in LIK, and the value of holistic sea-ice knowledge in detecting subtle, intertwined patterns of environmental change. The relevance of local, indigenous sea-ice expertise in helping advance adaptation and responses to climate change as well as its potential role in guiding research questions and hypotheses are also examined. The challenges that may have to be overcome in creating an interface for exchange between indigenous experts and seaice researchers are considered. Promising approaches to overcome these challenges include cross-cultural, interdisciplinary education, and the fostering of Communities of Practice.

    Full Text Available The diversity of yeasts collected from different sites in Antarctica (Admiralty Bay, King George Island and Port Foster Bay and Deception Island and their ability to produce extracellular enzymes and mycosporines were studied. Samples were collected during the austral summer season, between November 2006 and January 2007, from the rhizosphere of Deschampsia antarctica, ornithogenic (penguin guano soil, soil, marine and lake sediments, marine water and freshwater from lakes. A total of 89 isolates belonging to the following genera were recovered: Bensingtonia, Candida, Cryptococcus, Debaryomyces, Dioszegia, Exophiala, Filobasidium, Issatchenkia (Pichia, Kodamaea, Leucosporidium, Leucosporidiella, Metschnikowia, Nadsonia, Pichia, Rhodotorula, and Sporidiobolus, and the yeast-like fungi Aureobasidium, Leuconeurospora and Microglossum. Cryptococcus victoriae was the most frequently identified species. Several species isolated in our study have been previously reported to be Antarctic psychophilic yeasts, including Cr. antarcticus, Cr. victoriae, Dioszegia hungarica and Leucosporidium scottii. The cosmopolitan yeast species A. pullulans, C. zeylanoides, D. hansenii, I. orientalis, K. ohmeri, P. guilliermondii, Rh. mucilaginosa, and S. salmonicolor were also isolated. Five possible new species were identified. Sixty percent of the yeasts had at least one detectable extracellular enzymatic activity. Cryptococcus antarcticus, D. aurantiaca, D. crocea, D. hungarica, Dioszegia sp., E. xenobiotica, Rh. glaciales, Rh. laryngis, Microglossum sp. 1 and Microglossum sp. 2 produced mycosporines. Of the yeast isolates, 41.7% produced pigments and/or mycosporines and could be considered adapted to survive in Antarctica. Most of the yeasts had extracellular enzymatic activities at 4ºC and 20ºC, indicating that they could be metabolically active in the sampled substrates.

    Full Text Available Background: Candida species are responsible for various clinical manifestations from mucocutaneous overgrowth to blood stream infections especially in immunocompromized situations. Although C. albicans is the most prevalent species, high incidence of non-albicans Candida species with antifungal resistance are emerging which is posing a serious threat to the patients care.Objective: This study aimed to isolate and identify different species of Candida from different clinical specimens. Methods: A total of 100 different clinical specimens were studied of which 35 were oral swab, 28 were high vaginal swab, 15 were urine, 14 were nail, 04 were bronchoalveolar lavage and peritoneal fluid were 04. Among 100 clinical specimens, Candida isolates were identified in 64 specimens. Isolation of Candida species was done by primary culture in SDA. Subsequent identification of species were performed by germ tube test, subculture in chromo­genic agar medium and carbohydrate assimilation test with commonly used twelve sugars.Results: Out of 64 isolated Candida species, Candida albicans were 51.56% and the non-albicans Candida species were 48.44%. The most prevalent Candida species was C. albicans 33 (51.53% followed by C. tropicalis 17 (26.56%. C. glabrata 4 (6.25%, C. parapsilo­sis 4 (6.25%, C. krusei 3 (4.68% and C. guilliermondii 2 (3.2%. One of the isolated Candida species was unidentified.Conclusion: Though Candida albicans was found as the most common species, but non-albicans Candida species are appearing as emerging pathogens as well. Exposure to chemotherapy appeared to be the commonest predisposing factor for Candida infection followed by indwelling urinary catheter in situ for prolong period.

  11. A Global Assessment on Climate Research Engaging Indigenous Knowledge Systems and Recommendations for Quality Standards of Research Practice in Indigenous Communities

    Science.gov (United States)

    Davíd-Chavez, D. M.; Gavin, M. C.

    2017-12-01

    Indigenous communities worldwide have maintained their own knowledge systems for millennia informed through careful observation of dynamics of environmental changes. Withstanding centuries of challenges to their rights to maintain and practice these knowledge systems, Indigenous peoples continually speak to a need for quality standards for research in their communities. Although, international and Indigenous peoples' working groups emphasize Indigenous knowledge systems and the communities who hold them as critical resources for understanding and adapting to climate change, there has yet to be a comprehensive, evidence based analysis into how diverse knowledge systems are integrated in scientific studies. Do current research practices challenge or support Indigenous communities in their efforts to maintain and appropriately apply their knowledge systems? This study addresses this question using a systematic literature review and meta-analysis assessing levels of Indigenous community participation and decision-making in all stages of the research process (initiation, design, implementation, analysis, dissemination). Assessment is based on reported quality indicators such as: outputs that serve the community, ethical guidelines in practice (free, prior, and informed consent and intellectual property rights), and community access to findings. These indicators serve to identify patterns between levels of community participation and quality standards in practice. Meta-analysis indicates most climate studies practice an extractive model in which Indigenous knowledge systems are co-opted with minimal participation or decision-making authority from communities who hold them. Few studies report outputs that directly serve Indigenous communities, ethical guidelines in practice, or community access to findings. Studies reporting the most quality indicators were initiated in mutual agreement between Indigenous communities and outside researchers or by communities themselves

    2013-09-01

    Drawing upon on the literature on Indigenous values to water, water markets and the empirical findings from a survey of 120 Indigenous and non-Indigenous respondents across northern Australia, the paper makes important qualitative and statistical comparisons between Indigenous and non-Indigenous values to water markets. The study is the first comparison of Indigenous and non-Indigenous values to water markets based on the same survey instrument. Key results from Indigenous respondents include: (1) water markets are held to be an acceptable approach to managing water; (2) markets must be carefully designed to protect customary and ecological values; (3) the allocation of water rights need to encompass equity considerations; and (4) water and land rights should not be separated even if this enhances efficiency, as it runs counter to Indigenous holistic values. Overall, the survey results provide the basis for a proposed adaptive decision loop, which allows decision makers to incorporate stakeholder values in water markets.

    We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

  14. Developing an indigenous surgical workforce for Australasia.

    Progress has been made in Australia and New Zealand to increase the numbers of indigenous students (Aboriginal, Torres Strait Islander and Maori) entering primary medical qualification courses. In New Zealand, up to 20 Maori are graduating annually, with similar numbers possible in Australia, creating a potential opportunity to develop an indigenous surgical workforce. A literature review identified factors utilized by medical schools to attract indigenous students into medical careers and the interventions necessary to ensure successful graduation. A further search identified those factors important in encouraging indigenous medical graduates to enter specialist training programmes and achieve faculty appointments. All medical schools have utilized elements of a 'pipeline approach' encompassing contact with students at secondary school level to encourage aspirational goals and assist with suitable subject selection. Bridging courses can ensure students leaving school have appropriate skill sets before entering medical degree courses. Extensive practical help is available during primary medical qualification study. The elements necessary for primary medical qualification success - dedicated and focused study, developing appropriate skill sets, mentoring, support, and an institutional and collegial commitment to success - are also the elements required for postgraduate achievement. The Royal Australasian College of Surgeons (RACS) is primarily involved in training rather than service provision. The increasing numbers of indigenous medical graduates in both Australia and New Zealand represent an opportunity for the College to contribute to improving indigenous health status by implementing specific measures to increase numbers of indigenous surgeons. © 2013 Royal Australasian College of Surgeons.

    Full Text Available Abstract Background Indigenous Australians are known to be at greater risk of morbidity and mortality from mental health related conditions, but most available data relate to the use of mental health services, and little is known about other aspects of social and emotional wellbeing. Using the first available nationally representative data, we examined the prevalence and patterning of psychological distress among Indigenous Australian adults and compared these with corresponding data from the non-Indigenous population. Methods The analysis used weighted data on psychological distress, as measured by a modified Kessler Psychological Distress score (K5, and a range of socio-demographic measures for 5,417 Indigenous and 15,432 non-Indigenous adults aged 18-64 years from two nationally representative surveys. Very high psychological distress (VHPD was defined as a K5 score ≥ 15 (possible range = 5-25. Results Indigenous adults were about three times more likely than non-Indigenous adults to be classified with VHPD: 14.5% (95% confidence interval (CI 12.9-16.0% versus 5.5% (95% CI 5.0-5.9%. After adjusting for age, most socio-demographic variables were significantly associated with VHPD in both populations, although the relative odds were generally larger among non-Indigenous people. Indigenous people in remote areas had a lower prevalence of VHPD than their non-remote counterparts, and only marital status, main language, and food insecurity were significantly associated with VHPD in remote areas. Conclusions Higher absolute levels of VHPD combined with smaller socio-demographic gradients in the Indigenous population suggest the importance of risk factors such as interpersonal racism, marginalization and dispossession, chronic stress and exposure to violence that are experienced by Indigenous Australians with common and/or cross-cutting effects across the socioeconomic spectrum. The lower prevalence of VHPD and lack of association with many socio

    The western Amazon is the most biologically rich part of the Amazon basin and is home to a great diversity of indigenous ethnic groups, including some of the world's last uncontacted peoples living in voluntary isolation. Unlike the eastern Brazilian Amazon, it is still a largely intact ecosystem. Underlying this landscape are large reserves of oil and gas, many yet untapped. The growing global demand is leading to unprecedented exploration and development in the region. We synthesized information from government sources to quantify the status of oil development in the western Amazon. National governments delimit specific geographic areas or "blocks" that are zoned for hydrocarbon activities, which they may lease to state and multinational energy companies for exploration and production. About 180 oil and gas blocks now cover approximately 688,000 km(2) of the western Amazon. These blocks overlap the most species-rich part of the Amazon. We also found that many of the blocks overlap indigenous territories, both titled lands and areas utilized by peoples in voluntary isolation. In Ecuador and Peru, oil and gas blocks now cover more than two-thirds of the Amazon. In Bolivia and western Brazil, major exploration activities are set to increase rapidly. Without improved policies, the increasing scope and magnitude of planned extraction means that environmental and social impacts are likely to intensify. We review the most pressing oil- and gas-related conservation policy issues confronting the region. These include the need for regional Strategic Environmental Impact Assessments and the adoption of roadless extraction techniques. We also consider the conflicts where the blocks overlap indigenous peoples' territories.

    Ramat Hovav is a major chemical industrial park manufacturing pharmaceuticals, pesticides, and various aliphatic and aromatic halogens. All wastewater streams are collected in large evaporation ponds. Salinity in the evaporation ponds fluctuates between 3% (w/v) and saturation and pH values range between 2.0 and 10.0. We looked for microorganisms surviving in these extreme environmental conditions and found that 2 yeast strains dominate this biotope. 18S rDNA sequence analysis identified the isolates as Pichia guilliermondii and Rhodotorula mucilaginosa. Both isolates grew in NaCl concentrations ranging up to 3.5 M and 2.5 M, respectively, and at a pH range of 2-10. There was a distinct difference between the Rhodotorula and Pichia strains and S. cerevisiae RS16 that served as a control strain with respect to accumulation of osmoregulators and internal ion concentrations when exposed to osmotic stress. The Pichia and Rhodotorula strains maintained high glycerol concentration also in media low in NaCl. Utilization of various carbon sources was examined. Using a tetrazolium-based assay we show that the Rhodotorula and Pichia strains are capable of utilizing a wide range of different carbon sources including anthracene, phenanthrene, and other cyclic aromatic hydrocarbons.

    Full Text Available The current study sought to increase our understanding of the factors involved in the early vocabulary development of Australian Indigenous children. Data from the Longitudinal Study of Indigenous Children were available for 573 Indigenous children (291 boys who spoke English (M=37.0 months, SD=5.4 months, at wave 3. Data were also available for 86 children (51 boys who spoke an Indigenous language (M=37.1 months, SD=6.0 months, at wave 3. As hypothesised, higher levels of parent-child book reading and having more children’s books in the home were associated with better English vocabulary development. Oral storytelling in Indigenous language was a significant predictor of the size of children’s Indigenous vocabulary.

    Full Text Available Objective. To identify modifiable cardio-metabolic and lifestyle risk factors among indigenous populations from Australia (Aboriginal Australians/Torres Strait Islanders, New Zealand (Māori, and the United States (American Indians and Alaska Natives that contribute to cardiovascular disease (CVD. Methods. National health surveys were identified where available. Electronic databases identified sources for filling missing data. The most relevant data were identified, organized, and synthesized. Results. Compared to their non-indigenous counterparts, indigenous populations exhibit lower life expectancies and a greater prevalence of CVD. All indigenous populations have higher rates of obesity and diabetes, hypertension is greater for Māori and Aboriginal Australians, and high cholesterol is greater only among American Indians/Alaska Natives. In turn, all indigenous groups exhibit higher rates of smoking and dangerous alcohol behaviour as well as consuming less fruits and vegetables. Aboriginal Australians and American Indians/Alaska Natives also exhibit greater rates of sedentary behaviour. Conclusion. Indigenous groups from Australia, New Zealand, and the United States have a lower life expectancy then their respective non-indigenous counterparts. A higher prevalence of CVD is a major driving force behind this discrepancy. A cluster of modifiable cardio-metabolic risk factors precede CVD, which, in turn, is linked to modifiable lifestyle risk factors.

    Full Text Available Abstract Background Cardiovascular diseases contribute substantially to the poor health and reduced life expectancy of Indigenous Australians. Heart failure is a common, disabling, progressive and costly complication of these disorders. The epidemiology of heart failure and the adequacy of relevant health service provision in Indigenous Australians are not well delineated. Methods A systematic search of the electronic databases PubMed, Embase, Web of Science, Cinahl Plus, Informit and Google Scholar was undertaken in April 2012 for peer-reviewed journal articles relevant to the topic of heart failure in Indigenous Australians. Additionally, a website search was done to identify other pertinent publications, particularly government reports. Results There was a paucity of relevant peer-reviewed research, and government reports dominated the results. Ten journal articles, 1 published conference abstract and 10 reports were eligible for inclusion. Indigenous Australians reportedly have higher morbidity and mortality from heart failure than their non-Indigenous counterparts (age-standardised prevalence ratio 1.7; age-standardised hospital separation ratio ≥3; crude per capita hospital expenditure ratio 1.58; age-adjusted mortality ratio >2. Despite the evident disproportionate burden of heart failure in Indigenous Australians, the accuracy of estimation from administrative data is limited by poor indigenous identification, inadequate case ascertainment and exclusion of younger subjects from mortality statistics. A recent journal article specifically documented a high prevalence of heart failure in Central Australian Aboriginal adults (5.3%, noting frequent undiagnosed disease. One study examined barriers to health service provision for Indigenous Australians in the context of heart failure. Conclusions Despite the shortcomings of available published data, it is clear that Indigenous Australians have an excess burden of heart failure. Emerging data

    Lately, plastic bag is becoming the most important pollutant for environment since it is difficult to be naturally degraded due to it consists of long hydrocarbon polymer chains. Our previous study indicated that our pure isolate Pseudomonas PL-01 and Bacillus PL-01 could degrade about 10% plastic bag. This present study was aimed to find out whether Pseudomonas PL01 and Bacillus PL01 put a positive effect to indigenous bacteria from marginal area in doing plastic degradation with a soil burial method. Beach sand was used as a representative marginal area, and mangrove sediment was used as a comparison. Plastics were submerged into unsterile beach sand with 10% of Pseudomonas PL-01 or Bacillus PL-01 containing liquid minimal salt medium (MSM) separately, while other plastics were submerged into unsterile mangrove sediments. After 4, 8, 12 and 16 weeks, their biofilm formation on their plastic surfaces and plastic degradation were measured. Results indicated that those 2 isolates put positive influent on biofilm formation and plastic degradation for indigenous beach sand bacteria. Bacillus PL-01 put higher influent than Pseudomonas PL-01. Plastic transparent was preferable degraded than black and white plastic bag `kresek'. But anyhow, indigenous mangrove soil bacteria showed the best performance in biofilm formation and plastic degradation, even without Pseudomonas PL-01 or Bacillus PL-01 addition. Fourier Transform Infrared (FTIR) analysis complemented the results; there were attenuated peaks with decreasing peaks transmittances. This FTIR peaks indicated chemical functional group changes happened among the plastic compounds after 16 weeks incubation time.

    Full Text Available Background and Purpose: Candida species are the most opportunistic fungi affecting the nails and resulting in onychomycosis. In this study, we identified and evaluated in-vitro susceptibility of the recovered isolates against fluconazole (FLC, voriconazole (VRC, and clotrimazole (CLT using the Clinical and Laboratory Standards Institute (CLSI M27-A3 document. Materials and Methods: From patients with either clinically or mycologically proven onychomycosis, 97 isolates comprising of seven Candida species were isolated, which were identified by both conventional and molecular techniques such as polymerase chain reaction-restriction fragment length polymorphism. In addition, Candida dubliniensis was confirmed by restriction endonuclease analysis. Antifungal susceptibility of each isolate against the three azoles applied in this study was determined using the CLSI microdilution reference method M27-A3. Results: Candida parapsilosis (C. parapsilosis was the most frequently isolated species (n=44, followed by C. albicans (n=23, C. tropicalis (n=13, C. glabrata (n=7, C. krusei (n=6, C. guilliermondii (n=3, and C. dubliniensis (n=1. All the isolates were susceptible to CLT. VRC had lower minimum inhibitory concentration (MIC values for the isolates compared to FLC. Geometric mean MIC values of VRC, FLC, and CLT for C. parapsilosis isolates were 0.07 µg/ml, 0.8 µg/ml, and 0.35 µg/ml, respectively. Collectively, all species exhibited greater susceptibility to VRC in comparison to C. albicans (P≤0.001. Conclusion: This study showed that non-albicans Candida species were the most common etiologic agents of non-dermatophyte onychomycosis. The major antifungal agents used in clinics to empirically treat yeast onychomycosis are FLC and CLT. Our data suggested that CLT is a better choice for the treatment of Candida onychomycosis, especially in drug resistant cases.

    Full Text Available This paper presents the results of the project "We are the others: Identity and Territory Rikbaktsa”, developed under the Lato Sensu Specialization Course "Collaborative Management of Complex Social-ecological Systems in the Brazilian Amazon. The objective of the project conducted by the group of participants who focused on indigenous issues was to assess the social-ecological resilience of the Rikbaktsa indigenous people within the Escondido Indigenous Land (Cotriguaçu, Mato Grosso. The methodology was adapted from a tool developed by the group "Resilience Alliance", which enabled exploratory research focusing on the subjects: territorial reconfiguration from the 1950s; forms of use and occupation of the Escondido indigenous land; as well as challenges and lessons learned for the development of collaborative research methodologies with indigenous populations. Important attributes were identified for the resilience of the "Rikbaktsa System", in addition to factors of risk that threaten the territorial processes and resistance in which the Rikbaktsa are currently engaged. We also present reflections and recommendations for the application of concepts and methods of the complex social-ecological systems approach and principles of collaborative management with Amazonian indigenous peoples.

    Full Text Available Present study documents the potential probiotic Lactobacillus isolated from indigenous fermented beverage Raabadi, consumed during summers in Haryana and Rajasthan regions of India. A total of 5 Raabadi samples were collected aseptically and 54 isolates were purified using MRS medium. All the isolates were assessed for tolerance to low pH and bile salts. It was observed that out of 54 only 24 isolates could survive the simulated gastric conditions. These isolates were further evaluated in vitro for cell surface hydrophobicity, cell surface hydrophobicity, hypocholesteramic activity, anti-oxidative potential, BSH activity, antagonistic activity and antibiotic resistance profile. In addition, the confirmation of phenol resistance was also done. On the basis of results obtained, the survival rate of isolates was noted and 6 isolates were finally selected for further studies. Among them Lactobacillus plantarum RYPR1 and RYPC7 showed good survival at pH 2 which shows good acid tolerance. Moreover, Lactobacillus plantarum RYPR1 showed the highest hydrophobicity (79.13% and represented the deconjugation of bile salts, which help in their adhesion to epithelial cells and colonization. Furthermore, RYPR1 also exhibited highest cholesterol reduction (59% and subsequent analysis of results revealed that the above mentioned isolates further exhibit a good hypocholesterolemic effect and could be possibly used to prevent hypercholesterolemia. The present study divulges that Lactobacillus plantarum RYPR1 has an excellent probiotic potential.

    The burden of tuberculosis (TB) in the estimated 370 million indigenous peoples worldwide is unknown. To conduct a literature review to summarize the TB burden in indigenous peoples, identify gaps in current knowledge, and provide the foundation for a research agenda prioritizing indigenous health within TB control. A systematic literature review identified articles published between January 1990 and November 2011 quantifying TB disease burden in indigenous populations worldwide. Among the 91 articles from 19 countries included in the review, only 56 were from outside Australia, Canada, New Zealand and the United States. The majority of the studies showed higher TB rates among indigenous groups than non-indigenous groups. Studies from the Amazon generally reported the highest TB prevalence and incidence, but select populations from South-East Asia and Africa were found to have similarly high rates of TB. In North America, the Inuit had the highest reported TB incidence (156/100000), whereas the Metis of Canada and American Indians/Alaska Natives experienced rates of indigenous groups. Where data exist, indigenous peoples were generally found to have higher rates of TB disease than non-indigenous peoples; however, this burden varied greatly. The paucity of published information on TB burden among indigenous peoples highlights the need to implement and improve TB surveillance to better measure and understand global disparities in TB rates.

In the UN, indigenous peoples have achieved more than any other group of people, minorities included. The book...... traces this to the ability of indigenous peoples to create consensus among themselves; the establishment of an indigenous caucus; and the construction of a global indigenousness in a continuously developing process in which contentious relationships and symbols have been constructed, reformulated......, negotiated and re-negotiated internally and with the states.

    Full Text Available This paper is a review of the social conflicts of indigenous peoples especially in North Maluku. The purpose of this review is to find out some factors causing indigenous peoples social conflicts in North Maluku and to produce alternative solutions as a policy to develop indigenous peoples livelihoods. The review resulted in several factors causing social conflicts of indigenous peoples such as the unclear boundary between the two parties the customary violations by the forest businessmen the injustice of the law enforcement officers in solving the problems the destruction of the indigenous people and the forest community narrow forest the lack positive contribution of forest management so far to indigenous peoples and forest communities companies do not involve indigenous peoples andor forest communities in forest exploitation destruction of customary buildings as places of worship deforestation timber exploitation while timber by indigenous peoples is sacred wood or abstinence to be felled. Alternative solutions are required by local government such as policy on legal recognition of indigenous peoples indigenous peoples empowerment implementation of indigenous peoples aspirations indigenous peoples economic development based on local wisdom and dispute resolution of indigenous peoples through special courts of a holistic nature.

  6. Interpretation in Maori cultural tourism in New Zealand: Exploring the perspectives of indigenous and non-indigenous guides

    Full Text Available Cultural tourism experiences provide opportunities for cultural exchange between the host culture and visitors. With growing interest in indigenous tourism, the extent of indigenous control over cultural content and representation becomes increasingly important. In mana-ging interpretation processes, guides have an influential role in facilitating understanding and appreciation in visitors, thereby fostering respect for indigenous cultural heritage. In a guided tour this exchange is facilitated by the tour guide who needs to consider the diversity of the visitors’ characteristics. By taking a visitor-centred approach to guiding and interpretation, guides adjust the way the experience is managed so that it is interesting, meaningful and relevant.

    The potential for health promotion through social networking sites (SNSs) is widely recognized. However, while health promotion prides itself in focusing on the social determinants of health, its partiality for persuading individuals to comply with health behaviours dominates the way health promotion utilizes SNSs. This paper contributes to an understanding of collaborative ways SNSs can work for health promotion agendas of self-determination and empowerment in an Indigenous Australia context. An ethnographic study was undertaken with Deadly Choices, an Indigenous-led health promotion initiative. The study involved participant observation of interactions on Deadly Choices SNSs between Deadly Choices and its online community members. Deadly Choices provides an example of SNSs providing a powerful tool to create a safe, inclusive and positive space for Indigenous people and communities to profile their healthy choices, according to Indigenous notions of health and identity. The study found five principles that underpin Deadly Choices' use of SNSs for health promotion. These are: create a dialogue; build community online and offline; incentivise healthy online engagement; celebrate Indigenous identity and culture; and prioritize partnerships. Deadly Choices SNSs empowers Indigenous people and communities to be health promoters themselves, which represents a power shift from health promotion practitioner to Indigenous people and communities and more broadly, an enactment of Indigenous self-determination on SNSs. Mainstream health promotion can learn from Indigenous health promotion practice regarding the use of SNSs for health promotion agendas. © The Author 2017. Published by Oxford University Press.

    To evaluate published spirometry data for Australian Aboriginal and Torres Strait Islander (Indigenous) peoples to determine (i) whether their ethnicity influenced spirometry results; and (ii) if any reliable spirometry reference values exist for Indigenous Australians. Systematic review of published and grey literature. PubMed and Cochrane Library databases, references of included articles and appropriate grey literature. Last searches were conducted in April 2016. We included any study that performed spirometry on healthy Indigenous Australians and compared their results with those from people of European ancestry. Two authors independently screened titles and abstracts and then reviewed potentially relevant full-text articles for possible inclusion. We used PRISMA systematic review reporting methods to collate data. Of a possible 125 studies, 18 full-text articles were reviewed, but only nine fulfilled the inclusion criteria. None specified Torres Strait Islander inclusion. All studies reported lower spirometry values (as much as 30% lower) for Aboriginal people compared with non-Indigenous people. Five studies developed spirometry reference values for Indigenous Australians; however, none adhered to all participant inclusion and exclusion criteria outlined by the American Thoracic Society and European Respiratory Society. Hence, reported results and subsequent reference values may not be a true representation of spirometry values in healthy Indigenous people. The lower spirometry values reported for Indigenous Australians may be due to study limitations. Furthermore, there are currently no reliable spirometry reference values for Indigenous Australians that adhere to current guidelines. Developing a set of Indigenous Australian reference values will improve the accuracy of test interpretation and aid in the diagnosis of respiratory disease in this population.

    Biological antimicrobial compounds from yeast can be used to address the critical need for safer preservatives in food, fruit and beverages. The inhibition of Candida guilliermondii, a common fermented beverage spoilage organism, was achieved using antimicrobial compounds produced by Candida pyralidae KU736785. The antimicrobial production system was modelled and optimised using response surface methodology, with 22.5 ℃ and pH of 5.0 being the optimum conditions. A new concept for quantifying spoilage organism inhibition was developed. The inhibition activity of the antimicrobial compounds was observed to be at a maximum after 17-23 h of fermentation, with C. pyralidae concentration being between 0.40 and 1.25 × 10 9 CFU ml -1 , while its maximum specific growth rate was 0.31-0.54 h -1 . The maximum inhibitory activity was between 0.19 and 1.08 l contaminated solidified media per millilitre of antimicrobial compound used. Furthermore, the antimicrobial compound formation rate was 0.037-0.086 l VZI ml -1 ACU h -1 , respectively. The response surface methodology analysis showed that the model developed sufficiently described the antimicrobial compound formation rate 1.08 l VZI ml -1 ACU, as 1.17 l VZI ml -1 ACU, predicted under the optimum production conditions.

    Yuremamine was isolated and characterized from the stem bark of Mimosa tenuiflora. This plant is still used by indigenous peoples in North-eastern Brazil to make yurema, a psychoactive beverage that is used for medico-religious purpose ( jurema preta or vinho da jurema, in Portuguese). The characterization of this novel compound by NMR and mass spectrometry introduces a new class of phytoindoles.

    Full Text Available This paper begins with a poem and is inclusive of my voice as Anishinaabekwe (Ojibway woman and is authored from my spirit, heart, mind and body. The idea of social inclusion and Indigenous peoples leave more to the imagination and vision than what is the reality and actuality in Canada. This article begins with my location followed with skepticism and hope. Skepticism deals with the exclusion of Indigenous peoples since colonial contact and the subsequent challenges and impacts. Hope begins to affirm the possibilities, strengths and Indigenous knowledge that guides wholistic cultural frameworks and ethics of social inclusion. A wholistic cultural framework is presented; guided by seven sacred teachings and from each element thoughts for consideration are guided by Indigenous values and principles. From each element this paper presents a wholistic and ethical perspective in approaching social inclusion and Indigenous peoples.

    To evaluate the feasibility and reliability of record linkage of existing population-based data sets to determine Indigenous status among women receiving Pap smears. This method may allow for the first ever population measure of Australian Indigenous women's cervical screening participation rates. A linked data set of women aged 20-69 in the Queensland Pap Smear Register (PSR; 1999-2011) and Queensland Cancer Registry (QCR; 1997-2010) formed the Initial Study Cohort. Two extracts (1995-2011) were taken from Queensland public hospitals data (Queensland Hospital Admitted Patient Data Collection, QHAPDC) for women, aged 20-69, who had ever been identified as Indigenous (extract 1) and had a diagnosis or procedure code relating to cervical cancer (extract 2). The Initial Study Cohort was linked to extract 1, and women with cervical cancer in the initial cohort were linked to extract 2. The proportion of women in the Initial Cohort who linked with the extracts (true -pairs) is reported, as well as the proportion of potential pairs that required clerical review. After assigning Indigenous status from QHAPDC to the PSR, the proportion of women identified as Indigenous was calculated using 4 algorithms, and compared. There were 28,872 women (2.1%) from the Initial Study Cohort who matched to an ever Indigenous record in extract 1 (n=76,831). Women with cervical cancer in the Initial Study Cohort linked to 1385 (71%) records in extract 2. The proportion of Indigenous women ranged from 2.00% to 2.08% when using different algorithms to define Indigenous status. The Final Study Cohort included 1,372,823 women (PSR n=1,374,401; QCR n=1955), and 5,062,118 records. Indigenous status in Queensland cervical screening data was successfully ascertained through record linkage, allowing for the crucial assessment of the current cervical screening programme for Indigenous women. Our study highlights the need to include Indigenous status on Pap smear request and report forms in any

    The results of studies on the effect of near uv light on the yeast Candida guilliermondii are presented. It was shown that certain doses of 313 nm light inactivated the yeast. The detailed affect is shown in the loss of the ability of the cells to form microcolonies and outwardly does not differ from inactivation caused by 254 nm uv. It was concluded that the cell destruction caused by the 313 nm light was not due to damage to DNA. Experiments in which yeast cells were inactivated by 313 nm light before plating on agar and held for some time in a non-nutrient medium permitted observation of recovery of their viability. A difference was shown in the level of repair of yeasts irradiated by 313 nm light (up to 100% recovery) and 254 nm light (60% recovery). The nature of the dependence of the photoprotection on the 313 nm light dose was determined. A decrease in photoprotection was noted, starting with 7x10 -7 einstein/cm 2 , with its complete disappearance upon further dose increase. It is suggested that, in this recovery of the yeast, some other, thus far unknown, mechanism participates. Data were obtained on the survival of yeast irradiated with lethal uv doses. Of special importance, in the authors' opinion, is the fact that, for the photoprotection effect to appear, some time is needed between actions of the 313 and 254 nm lights, which suggests a photoinduced formation in the yeast cells of compounds that protect them from lethal injury

  15. Effects of development on indigenous dietary pattern: A Nigerian case study.

    The traditional foods of indigenous people in Nigeria are known for their cultural symbolism and agricultural biodiversity which contributes to their daily healthy and rich diet. In the early 90s, rapid development of the Federal Capital Territory (FCT) was noted and the resettlement of indigenes to other parts of the region was reported. These changes have facilitated the modification of indigenous diets, as indigenous groups rapidly embraced modern foods and also adopted the food culture of migrant ethnic groups. This has led to a gradual erosion of indigenous diets and traditional food systems in the FCT. This study explored the impact of development on traditional food systems and determined indigenes perception of the modification to their food culture as a result of the development of their land within the FCT. Field survey was carried out in four indigenous communities in the FCT (30 indigenes from each of the four areas) using structured questionnaires, Focus Group Discussions (FGDs) and key informant interviews. Person Chi Square analysis of indigenes socio-economic characteristics revealed significant relationships between gender of indigenes and farm size, Age and farm size, Educational level and farm/herd size. Qualitative analysis of FGDs revealed indigenes opinion on the socio-cultural changes in behaviour and food systems as a result of development. The study also identified indigenous youths as being most influenced by development especially through education, white collar jobs and social interactions with migrant ethnic groups in the FCT. The study recommended that indigenes should be provided with more secure land tenure and "back-to-farm" initiatives should be put in place by the Nigerian government to encourage indigenous youth to engaged more in agriculture.

  18. Indigenous environmental values as human values

    Monica Gratani

    2016-12-01

    Full Text Available The claim that in natural resource management (NRM a change from anthropocentric values and ethics to eco-centric ones is necessary to achieve sustainability leads to the search for eco-centric models of relationship with the environment. Indigenous cultures can provide such models; hence, there is the need for multicultural societies to further include their values in NRM. In this article, we investigate the environmental values placed on a freshwater environment of the Wet Tropics by a community of indigenous Australians. We discuss their environmental values as human values, and so as beliefs that guide communities’ understanding of how the natural world should be viewed and treated by humans. This perspective represents a step forward in our understanding of indigenous environmental values, and a way to overcome the paradigm of indigenous values as valued biophysical attributes of the environment or processes happening in landscapes. Our results show that the participant community holds biospheric values. Restoring these values in the NRM of the Wet Tropics could contribute to sustainability and environmental justice in the area.

    Full Text Available Considering the frequent rights violations perpetrated against indigenous peoples, which affect people and territories, compromising their lives and even their right to mourn the dead, it is imperative to understand the care and concerns of the indigenous towards life and death. Thus, we propose to analyze ethnographic narratives about the Apinayé, Ka'apor, Tapirapé, Tembé, Tenetehara, Terena and Asurini, in order to discuss the caring of people, considering the context of funerary rituals. The texts analyzed are able to reveal: (1 the existence (or not of the practice; (2 the specific contexts in which the funeral rites are (or not practiced; and (3 the meanings that the practice gain in ethnically differentiated societies. The narratives of indigenous peoples are included in order to attempt to make the peoples that nowadays find themselves accused by both the media and (reportedly pro-life organizations “be heard”. Therefore, using the classical literature we study the heritage of ritual practices, which besides confering dignity to the dead, indicate that life is the greater good among indigenous peoples.

    2002-01-01

    Full Text Available In order to develop an efficient an system for waste water pretreatment, the isolation of indigenous population of microorganisms from pharmaceutical waste water was done. We obtained pure cultures of 16 yeast isolates that differed slightly in colony morphology. Ten out of 16 isolates efficiently reduced COD in pharmaceutical waste water. Initial physiological characterization failed to match the 10 yeast isolates to either Pichia anomala or Pichia ciferrii. Restriction analysis of rDNA (rDNA-RFLP using three different restriction enzymes: HaeIII, MspI and CfoI, showed identical patterns of the isolates and Pichia anomala type strain. Separation of chromosomal DNAs of yeast isolates by the pulsed field gel electrophoresis revealed that the 10 isolates could be grouped into 6 karyotypes. Growth characteristics of the 6 isolates with distinct karyotypes were then studied in batch cultivation in pharmaceutical waste water for 80 hours.

    Indigenous peoples have received much attention as potential resource managers of threatened tropical forest ecosystems. Using data from Latin America, this article argues that fundamental changes need to take place in the legal recognition and demarcation of indigenous territories in order for this potential to be fulfilled. A comparison is made between different national land-tenure models for forest-dwelling indigenous peoples and a new model proposed by Latin American indigenous organizations. This comparison suggests that not only do indigenous peoples need to be provided with some degree of control over their territories and resources, but there needs to be a new type of partnership among indigenous peoples, the scientific community, national governments and international development agencies for the management of tropical forests. 37 refs, 3 tabs

    Background To describe suicide rates in the indigenous and non-indigenous populations of the Nenets Autonomous Okrug (NAO) in 2002–2012, as well as associated socio-demographic characteristics. Study design Retrospective population-based mortality study. Methods Data from autopsy reports were used to identify 252 cases of suicide in the NAO in 2002–2012. Data on socio-demographic characteristics of these cases were obtained from passports and medical records at local primary health care units, and were then linked to total population data from the Censuses in 2002 and 2010. Suicide rates for the indigenous Nenets population and the non-indigenous population were standardized to the European standard population. The rates were also estimated according to different socio-demographic characteristics and compared by calculating relative risks. Results The crude suicide rates were 79.8 per 100,000 person-years (PYs) in the Nenets population and 49.2 per 100,000 PYs in the non-indigenous population. The corresponding standardized estimates were 72.7 per 100,000 PYs and 50.7 per 100,000 PYs. The highest suicide rates in the Nenets population were observed in the age group 20–29 years (391 per 100,000 PYs), and in females aged 30–39 years (191 per 100,000 PYs). Socio-demographic characteristics associated with high suicide rates in the Nenets population were age 20–39 years, male, urban residence, having secondary school or higher education, being an employee or employer, and being single or divorced. Males aged 20–29 years, and females aged 30–39 and aged 70 years and above had the highest suicide rates in the non-indigenous population (137.5, 21.6 and 29.9 per 100,000 PYs, respectively). The elevated suicide rates observed in the non-indigenous population were associated with male sex, rural residence, secondary school education, being an employee or employer, and being single or divorced. Conclusions Suicide rates in the NAO were substantially higher among

    Full Text Available This paper seeks to provide an initial theoretical grounding to assess a practical project: a new software application that attempts to be a beneficial resource in the field of Indigenous representation. As a starting point, we are concerned to provide a theoretical ground for considering the inherited and shifting spaces of Indigenous media representation. To this end, this paper reconsiders the strengths and weaknesses of debates surrounding the ‘Indigenous public sphere’. This is used as grounds for critically understanding the relations that constitute this field. Following this, we consider how a more materialist approach to publics might enable a productive reconceptualization, and in particular how digital media initiatives and shifting news markets may be contributing to change. Finally, drawing on this model, we outline both the ‘Wakul app’ project, and how this framework might inform an assessment of its impact.

    Indigenous peoples living with HIV are less likely than non-Indigenous peoples living with HIV to access antiretroviral therapy; however, there is not enough contextual information surrounding this issue. The Indigenous Red Ribbon Storytelling Study was conducted in part to examine how Indigenous peoples living with HIV construct and understand their experiences accessing antiretroviral therapy. Our study design was critical Indigenous qualitative research, using the Behavioral Model of Health Services Use and community-based participatory research approaches. The study was conducted in partnership with Indigenous and non-Indigenous organizations. Study participants were adults from two Canadian cities. The study methods included 20 individual and two Indigenous sharing circle interviews, six participant observation sessions, a short survey and thematic analysis. Accessing antiretroviral therapy within the context of living with a substance use disorder was an overarching theme. Indigenous peoples living with HIV felt they had to choose between living with their active substance use disorder and accessing antiretroviral therapy. They felt misunderstood as a person living with a substance use disorder and often felt coerced into using antiretroviral therapy. Despite these challenges, they persevered as Indigenous peoples living with HIV and a substance use disorder. Further research on antiretroviral therapy access among Indigenous peoples living with HIV and a substance use disorder, particularly from the perspective of health service providers, is needed.

    Dudgeon, Pat; Holland, Christopher

    2018-04-01

    Suicide is an Aboriginal and Torres Strait Islander (hereafter 'Indigenous') population health issue. Over 2015-2016, the Aboriginal and Torres Strait Islander Suicide Prevention Project (ATSISPEP) aimed to identify success factors in Indigenous suicide prevention. For non-Indigenous practitioners working with indigenous clients at risk of suicide, ATSISPEP identified important considerations to make treatment more effective. The start is acknowledging the differences in the historical, cultural, political, social and economic experiences of Indigenous peoples, and their greater exposure to trauma, psychological distress and risks to mental health. These mental health difficulties are specific and more prevalent amongst Indigenous peoples and communities due to the ongoing impacts of colonisation in Australia including a range of social determinants impacting on the well-being of Indigenous peoples today. Working effectively with Indigenous clients also includes being able to establish culturally safe work environments, and the ability of non-Indigenous practitioners to work in a culturally competent and trauma-informed manner. There are also considerations regarding time protocols and client follow-up. Further, postvention responses might be required. Supporting selective suicide prevention activity among younger people (and other groups at increased risk) and community-level work is an important complement to working with Indigenous individuals at risk of suicide.

    Grape must harbors a complex community of yeast species responsible for spontaneous alcoholic fermentation. Although there are detailed studies on the microbiota of Vitis vinifera L. grapes, less is known about the diversity and behavior of yeast communities present on fermenting grape must from other species of Vitis. In this work, we used a culture-dependent method to study the identity and dynamics of the indigenous yeast population present during the spontaneous fermentation of Isabella (Vitis labrusca L.) grape must. Alcoholic fermentation was conducted using standard enological practices, and the associated non-Saccharomyces and S. cerevisiae yeast community was analyzed using selective growth media and 5.8-ITS DNA sequencing. Candida californica, Candida hellenica, Starmerella bacillaris (synonym Candida zemplinina), Hanseniaspora uvarum, and Hanseniaspora vineae were the main non-Saccharomyces species identified on Isabella fermenting must. Issatchenkia hanoiensis, a yeast species rarely found on Vitis vinifera L. grapes, was also recognized on Isabella grape must. Candida azymoides, Candida californica and Pichia cecembensis, identified in this work on Isabella fermenting must, have not previously been found on Vitis vinifera L. grape must. Interestingly, C. azymoides, I. hanoiensis and P. cecembensis have recently been isolated from the surface of Vitis labrusca L. grapes from vineyards in the Azores archipelago, suggesting that specific Vitis-yeast species associations are formed independently of geographic origin. We suggest that C. azymoides, C. californica, and P. cecembensis are yeast species preferentially associated with Vitis labrusca L. grapes. Specific biological interactions between grapevines and yeast species may underlie the assembly of differential Vitis-microbial communities. PMID:28424672

    Full Text Available Australia’s civil service has had some success in attracting substantial numbers of Indigenous employees. But significant numbers also regularly exit the bureaucracy. Retaining Indigenous employees is recognised as an ongoing difficulty for government. This research with former and current Indigenous civil servants outlines factors they identify as contributing to decisions to leave the bureaucracy. A key finding involves their general sense of being underutilised and undervalued— that forms of experience and understanding as Indigenous people go largely unrecognised within government, which in turn constrains their potential to meaningfully contribute to improving government relations with Indigenous Australians or to enhancing the effectiveness of the bureaucracy more broadly. Work as an Indigenous civil servant emerges as a space of contestation with the possibilities and limits of statecraft.

    Full Text Available Abstract Background Canada, the United States, Australia, and New Zealand consistently place near the top of the United Nations Development Programme's Human Development Index (HDI rankings, yet all have minority Indigenous populations with much poorer health and social conditions than non-Indigenous peoples. It is unclear just how the socioeconomic and health status of Indigenous peoples in these countries has changed in recent decades, and it remains generally unknown whether the overall conditions of Indigenous peoples are improving and whether the gaps between Indigenous peoples and other citizens have indeed narrowed. There is unsettling evidence that they may not have. It was the purpose of this study to determine how these gaps have narrowed or widened during the decade 1990 to 2000. Methods Census data and life expectancy estimates from government sources were used to adapt the Human Development Index (HDI to examine how the broad social, economic, and health status of Indigenous populations in these countries have changed since 1990. Three indices – life expectancy, educational attainment, and income – were combined into a single HDI measure. Results Between 1990 and 2000, the HDI scores of Indigenous peoples in North America and New Zealand improved at a faster rate than the general populations, closing the gap in human development. In Australia, the HDI scores of Indigenous peoples decreased while the general populations improved, widening the gap in human development. While these countries are considered to have high human development according to the UNDP, the Indigenous populations that reside within them have only medium levels of human development. Conclusion The inconsistent progress in the health and well-being of Indigenous populations over time, and relative to non-Indigenous populations, points to the need for further efforts to improve the social, economic, and physical health of Indigenous peoples.

    Cardiovascular diseases (CVD) are leading causes of mortality and morbidity among Indigenous people in New Zealand, Australia and Canada and are a major driver of the inequities in life expectancy between Indigenous and non-Indigenous people in these countries. Evidence-based pharmaceutical management of CVD can significantly reduce mortality and morbidity for persons diagnosed with CVD or for those at intermediate or high risk of CVD. Health literacy has been identified as a major barrier in the communication and implementation of appropriate pharmaceutical management plans for CVD. Addressing health literacy is particularly relevant in Indigenous populations where there are unique health and adult literacy challenges. This study will examine the effect of a customized, structured CVD medication programme, delivered by health professionals, on the health literacy of Indigenous people with, or at risk, of CVD. Primary outcomes are patient's knowledge about CVD medications; secondary outcomes examine changes in health literacy skills and practices. The study will employ a multi-site pre-post design with multiple measurement points to assess intervention efficacy. Participants will be recruited from four Indigenous primary care services in Australia, Canada and New Zealand. Three educational sessions will be delivered over four weeks. A tablet application will support the education sessions and produce a customized pill card for each participant. Participants will be provided with written information about CVD medications. Medication knowledge scores, and specific health literacy skills and practices will be assessed before and after the three sessions. Statistical analyses will identify significant changes in outcomes over each session, and from the pre-session one to post-session three time points. This study will make an important contribution to understanding the effect of a structured primary care-based intervention on CVD health literacy in Indigenous

    2013-12-01

    Indigenous communities have long experienced exploitation by researchers and increasingly require participatory and decolonizing research processes. We present a case study of an intervention research project to exemplify a clash between Western research methodologies and Indigenous methodologies and how we attempted reconciliation. We then provide implications for future research based on lessons learned from Native American community partners who voiced concern over methods of Western deductive qualitative analysis. Decolonizing research requires constant reflective attention and action, and there is an absence of published guidance for this process. Continued exploration is needed for implementing Indigenous methods alone or in conjunction with appropriate Western methods when conducting research in Indigenous communities. Currently, examples of Indigenous methods and theories are not widely available in academic texts or published articles, and are often not perceived as valid.

    Migrants may become entrepreneurs in their host countries. They may utilize their dual embeddedness in both the home country and the host country, and also use transnational links to gain a competitive advantage in exporting compared to indigenous entrepreneurs. Migrant entrepreneurs’ advantage may......, however, be contingent on attributes such as gender and education, especially among the first generation of migrants, in that being male and educated is more advantageous for migrants than for indigenous entrepreneurs. A representative sample of 50,371 entrepreneurs establishing or operating enterprises...... around the world was surveyed in the Global Entrepreneurship Monitor, which reports on migration and exporting.

  19. Indigenous Storytelling and Participatory Action Research

    2015-01-01

    Storytelling, in its various forms, has often been described as a practice with great emancipatory potential. In turn, Indigenous knowledge shows great promise in guiding a participatory action research (PAR) methodology. Yet these two approaches are rarely discussed in relation to one another, nor, has much been written in terms of how these two approaches may work synergistically toward a decolonizing research approach. In this article, I report on a community-driven knowledge translation activity, the Peoples’ International Health Tribunal, as an exemplar of how narrative and PAR approaches, guided by local Indigenous knowledge, have great potential to build methodologically and ethically robust research processes. Implications for building globally relevant research alliances and scholarship are further discussed, particularly in relation to working with Indigenous communities. PMID:28462305

    Background Airborne allergens vary from one climatic region to another. Therefore, it is important to analyze the environment of the region to select the most prevalent allergens for the diagnosis and treatment of allergic patients. Objective To evaluate the prevalence of positive skin tests to pollen and fungal allergens collected from local indigenous plants or isolated molds, as well as other outdoor and indoor allergens in allergic patients in 6 different geographical areas in the Kingdom of Saudi Arabia (KSA), the United Arab Emirates, and Sudan. Materials and methods Four hundred ninety-two consecutive patients evaluated at different Allergy Clinics (276 women and 256 men; mean age, 30 years) participated in this study. The selection of indigenous allergens was based on research findings in different areas from Riyadh and adjoining areas. Indigenous raw material for pollen grains was collected from the desert near the capital city of Riyadh, KSA. The following plants were included: Chenopodium murale, Salsola imbricata, Rumex vesicarius, Ricinus communis, Artiplex nummularia, Amaranthus viridis, Artemisia monosperma, Plantago boissieri, and Prosopis juliflora. Indigenous molds were isolated from air sampling in Riyadh and grown to obtain the raw material. These included the following: Ulocladium spp., Penicillium spp., Aspergillus fumigatus, Cladosporium spp., and Alternaria spp. The raw material was processed under Good Manufacturing Practices for skin testing. Other commercially available outdoor (grass and tree pollens) and indoor (mites, cockroach, and cat dander) allergens were also tested. Results The highest sensitization to indigenous pollens was detected to C. murale (32%) in Khartoum (Sudan) and S. imbricata (30%) and P. juliflora (24%) in the Riyadh region. The highest sensitization to molds was detected in Khartoum, especially to Cladosporium spp. (42%), Aspergillus (40%), and Alternaria spp. (38%). Sensitization to mites was also very prevalent

    Mainstream child and family well-being indicators frequently are based on measuring health, economic, and social deficits, and do not reflect Indigenous holistic and strength-based definitions of health and well-being. The present article is a review of literature that features Indigenous communities' self-identified strength-based indicators of child and family well-being. The literature search included Indigenous communities from across the world, incorporating findings from American Indians and Alaska Natives, First Nations, Native Hawaiians, Māori, Aboriginal Australians, and Sámi communities. Sorting the identified indicators into the quadrants of the Relational Worldview, an Indigenous framework for well-being based on medicine wheel teachings that views health and well-being as a balance among physical, mental, contextual, and spiritual factors, the authors discuss the findings.

    Indigenous peoples have worse health than non-Indigenous, are over-represented amongst the poor and disadvantaged, have lower life expectancies, and success in improving disparities is limited. To address this, research usually focuses on disadvantaged and marginalised groups, offering only partial understanding of influences underpinning slow progress. Critical analysis is also required of those with the power to perpetuate or improve health inequities. In this paper, using Australia as a case example, we explore the effects of 'White', Anglo-Australian cultural dominance in health service delivery to Indigenous Australians. We address the issue using race as an organising principle, underpinned by relations of power. Interviews with non-Indigenous medical practitioners in Western Australia with extensive experience in Indigenous health encouraged reflection and articulation of their insights into factors promoting or impeding quality health care to Indigenous Australians. Interviews were audio-taped and transcribed. An inductive, exploratory analysis identified key themes that were reviewed and interrogated in light of existing literature on health care to Indigenous people, race and disadvantage. The researchers' past experience, knowledge and understanding of health care and Indigenous health assisted with data interpretation. Informal discussions were also held with colleagues working professionally in Indigenous policy, practice and community settings. Racism emerged as a key issue, leading us to more deeply interrogate the role 'Whiteness' plays in Indigenous health care. While Whiteness can refer to skin colour, it also represents a racialized social structure where Indigenous knowledge, beliefs and values are subjugated to the dominant western biomedical model in policy and practice. Racism towards Indigenous patients in health services was institutional and interpersonal. Internalised racism was manifest when Indigenous patients incorporated racist

    This study was designed to investigate the microorganisms associated with palm oil mill effluent (POME) in Johor Bahru state, Malaysia. Biodegradation of palm oil mill effluents (POME) was conducted to measure the discarded POME based on physicochemical quality. The bacteria that were isolated are Micrococcus species, Bacillus species, Pseudomonas species, and Staphylococcus aureus, while the fungi that were isolated are Aspergillus niger, Aspergillus fumigatus, Candida species, Fusarium species, Mucor species, and Penicillium species. The autoclaved and unautoclaved raw POME samples were incubated for 7 days and the activities of the microorganisms were observed each 12 hours. The supernatants of the digested POME were investigated for the removal of chemical oxygen demand (COD), color (ADMI), and biochemical oxygen demand (BOD) at the end of each digestion cycle. The results showed that the unautoclaved raw POME sample degraded better than the inoculated POME sample and this suggests that the microorganisms that are indigenous in the POME are more effective than the introduced microorganisms. This result, however, indicates the prospect of isolating indigenous microorganisms in the POME for effective biodegradation of POME. Moreover, the effective treatment of POME yields useful products such as reduction of BOD, COD, and color.

    This paper reports on the isolation and identification of antibacterial constituents from the indigenous Australian medicinal plant Eremophila duttonii F. Muell. (Myoporaceae). Preparations derived from this plant are used by indigenous populations in the topical treatment of minor wounds, otitis and ocular complaints, and as a gargle for sore throat. Several authors have reported extracts of this plant to effect rapid bacteriolysis and inhibit growth of a wide range of Gram-positive micro-organisms. In other studies involving screening of native medicinal plants for antibacterial activity, extracts of Eremophila duttonii have been reported to consistently exhibit the highest potency amongst all species included. From a hexane extract, we identified two diterpenes of the serrulatane class, the principal constituents responsible for antibacterial activity and present as major constituents of the resinous leaf cuticle: serrulat-14-en-7,8,20-triol (1) and serrulat-14-en-3,7,8,20-tetraol (2). In addition, a hydroxylated furanosesquiterpene with mild antibacterial activity which appeared to be a novel compound was isolated from the extract and tentatively identified as 4-hydroxy-4-methyl-1-(2,3,4,5-tetrahydro-5-methyl[2,3'-bifuran]-5-yl) pentan-2-one. Minimum inhibitory concentrations for each of the compounds against three Gram-positive bacteria: Staphylococcus aureus (ATCC 29213), Staphylococcus epidermidis (ATCC 12228) and Streptococcus pneumoniae (ARL 10582), were determined using a micro-titre plate broth dilution assay.

  14. Traditional Indigenous Approaches to Healing and the modern welfare of Traditional Knowledge, Spirituality and Lands: A critical reflection on practices and policies taken from the Canadian Indigenous Example

    2011-10-01

    Full Text Available In order for traditional knowledge to be maintained and to develop, it has to be practiced. Traditional healing provides a vehicle for this to occur. In Canada, the spiritual revitalization of Indigenous communities and individuals often involves the use numerous components of traditional healing. These elements are reflectedmost clearly at the grassroots level, however, current Indigenous programs delivered by Indigenous and governmental agencies have made some accommodating efforts as well. Perhaps most importantly, traditional knowledge and Indigenous spirituality hinges on the maintenance and renewal of relationships to the land.Indigenous land bases and the environment as a whole remain vitally important to the practice of traditional healing.A focus on Indigenous healing, when discussing Indigenous knowledge systems and spirituality, is paramount today due to the large scale suppression of Indigenous cultural expressions during the process of colonization. With respect to policy, there appears to be a historical progression of perception or attitude towards Indigenous traditional healing in Canada from one of disfavour to one favour. There are nevertheless continuing challenges for traditional healing. Mainstream perceptions and subsequent policy implementations sometimes still reflect attitudes that were formulated during the decline of traditional healing practice during colonization processes. As a consequence the ability for particular communities to maintain and use their specific understandings ofIndigenous knowledge continues encounter obstacles. Indigenous Knowledge systems are living entities and not relics of the past. Today, these knowledge systems are still greatly being applied to help Indigenous communities and Indigenous people recover fromintergenerational pain and suffering endured during the colonization process. Future policy development and implementation should aim to support Indigenous peoples and communities when

  16. REDD+ and the Indigenous Question: A Case Study from Ecuador

    Directory of Open Access Journals (Sweden)

    Pablo Reed

    2011-04-01

    Full Text Available One of the main issues regarding the implementation of REDD+ in Latin America has been the growing concern that such projects may infringe upon the rights and negatively affect the livelihoods of forest-dependent communities. Various indigenous and civil society organizations are ardently opposed to the initiative. Such is the case in Ecuador, where indigenous opposition to REDD+ represents a considerable obstacle in the creation of a national strategy since more than 60% of the country’s remaining forest cover is on indigenous land or under indigenous occupation. Thus one of the most critical challenges remaining for Ecuador will be the construction of a strong legal, financial, and institutional framework—one that the greater indigenous community might be willing to accept. Closer examination of this topic however, reveals just how difficult this may become. Lack of information, a recent political split between national authorities and the indigenous sector, and the dissimilar organizational capacity levels of indigenous communities make the feasibility of carrying out REDD+ projects on these lands extremely complex. However, the biggest obstacle may be ideological. Many indigenous groups view REDD+, with its possible emphasis on international markets and neoliberal mechanisms, as a continuation of the type of policies that have impeded their quest for sovereignty and self determination. As such, indigenous people are only willing to consider such projects if they clearly see preconditions in place that would safeguard their cultures, territories, and autonomy.

    Winemaking is a highly industrialized process and a number of commercial Saccharomyces cerevisiae strains are used around the world, neglecting the diversity of native yeast strains that are responsible for the production of wines peculiar flavours. The aim of this study was to in-depth establish the S. cerevisiae volatile metabolome and to assess inter-strains variability. To fulfill this objective, two indigenous strains (BT2652 and BT2453 isolated from spontaneous fermentation of grapes collected in Bairrada Appellation, Portugal) and two commercial strains (CSc1 and CSc2) S. cerevisiae were analysed using a methodology based on advanced multidimensional gas chromatography (HS-SPME/GC×GC-ToFMS) tandem with multivariate analysis. A total of 257 volatile metabolites were identified, distributed over the chemical families of acetals, acids, alcohols, aldehydes, ketones, terpenic compounds, esters, ethers, furan-type compounds, hydrocarbons, pyrans, pyrazines and S-compounds. Some of these families are related with metabolic pathways of amino acid, carbohydrate and fatty acid metabolism as well as mono and sesquiterpenic biosynthesis. Principal Component Analysis (PCA) was used with a dataset comprising all variables (257 volatile components), and a distinction was observed between commercial and indigenous strains, which suggests inter-strains variability. In a second step, a subset containing esters and terpenic compounds (C10 and C15), metabolites of particular relevance to wine aroma, was also analysed using PCA. The terpenic and ester profiles express the strains variability and their potential contribution to the wine aromas, specially the BT2453, which produced the higher terpenic content. This research contributes to understand the metabolic diversity of indigenous wine microflora versus commercial strains and achieved knowledge that may be further exploited to produce wines with peculiar aroma properties.

    2016-01-01

    Coastal Indigenous peoples rely on ocean resources and are highly vulnerable to ecosystem and economic change. Their challenges have been observed and recognized at local and regional scales, yet there are no global-scale analyses to inform international policies. We compile available data for over 1,900 coastal Indigenous communities around the world representing 27 million people across 87 countries. Based on available data at local and regional levels, we estimate a total global yearly seafood consumption of 2.1 million (1.5 million-2.8 million) metric tonnes by coastal Indigenous peoples, equal to around 2% of global yearly commercial fisheries catch. Results reflect the crucial role of seafood for these communities; on average, consumption per capita is 15 times higher than non-Indigenous country populations. These findings contribute to an urgently needed sense of scale to coastal Indigenous issues, and will hopefully prompt increased recognition and directed research regarding the marine knowledge and resource needs of Indigenous peoples. Marine resources are crucial to the continued existence of coastal Indigenous peoples, and their needs must be explicitly incorporated into management policies.

    Despite the strong association between obesity and binge eating, limited research has examined the implications of binge eating on dietary adherence and psychological factors in ethnically diverse type 2 diabetes patients. This study investigated the prevalence of binge eating and its association with dietary adherence, glycemic control, and psychological factors among indigenous and non-indigenous type 2 diabetes patients in Chile. Participants were 387 indigenous (Mapuche) and non-indigenous (non-Mapuche) adults with type 2 diabetes. Self-report measures of binge eating, dietary adherence, diet self-efficacy, body image dissatisfaction, and psychological well-being were administered. Participants' weight, height, and glycemic control (HbA(1c)) were also obtained. Approximately 8 % of the type 2 diabetes patients reported binge eating. The prevalence among Mapuche patients was 4.9 %, and among non-Mapuche patients, it was 9.9 %. Compared to non-binge eaters, binge eating diabetes patients had greater body mass index values, consumed more high-fat foods, were less likely to adhere to their eating plan, and reported poorer body image and emotional well-being. Results of this study extend previous research by examining the co-occurrence of binge eating and type 2 diabetes as well as the associated dietary behaviors, glycemic control, and psychological factors among indigenous and non-indigenous patients in Chile. These findings may increase our understanding of the health challenges faced by indigenous populations from other countries and highlight the need for additional research that may inform interventions addressing binge eating in diverse patients with type 2 diabetes.

    Arsenic (As) biotransformation and release by indigenous bacteria from As rich groundwater was investigated. Metabolic landscape of 173 bacterial isolates indicated broad catabolic repertoire including abundance of As(5+) reductase activity and abilities in utilizing wide ranges of organic and inorganic respiratory substrates. Abundance of As homeostasis genes and utilization of hydrocarbon as carbon/electron donor and As(5+) as electron acceptor were noted within the isolates. Sediment microcosm study (for 300 days) showed a pivotal role of metal reducing facultative anaerobic bacteria in toxic As(3+) release in aqueous phase. Inhabitant bacteria catalyze As transformation and facilitate its release through a cascade of reactions including mineral bioweathering and As(5+) and/or Fe(3+) reduction activities. Compared to anaerobic incubation with As(5+) reducing strains, oxic state and/or incubation with As(3+) oxidizing bacteria resulted in reduced As release, thus indicating a strong role of such condition or biocatalytic mechanism in controlling in situ As contamination.

    Full Text Available Adopting the theories postulated by Classical Rhetoric and Argumentation Discourse, this paper comes up with a reflection about the identity built by Daniel Munduruku in his memories ‘Meu vô Apolinário: um mergulho no rio da (minha memória’ The indigenous writer assumes the world of classical rhetorical tradition and expose his ideas in order to change preconceived concepts about the visibility of indigenous people by non-indigenous brazilian society. Munduruku shows a new indigenous appearence resulting from the performance between previosly and shown ethos, working both: his ‘fame’ and a new person built in his book and captured by the reader. Adopting gender epidictic, the construction of the indigenous ethos is done in a apparently harmless way, lying hidden the purpose to recreate new values about the world’s indigenous peoples in Brazil.

    Oil pollution is a major environmental concern in many countries, and this has led to a concerted effort in studying the feasibility of using oil-degrading bacteria for bioremediation. Although many oil-degrading bacteria have been isolated from different environments, environmental conditions can impose a selection pressure on the types of bacteria that can reside in a particular environment. This study reports the successful isolation of two indigenous naphthalene-degrading bacteria from oil-contaminated tropical marine sediments by enrichment culture. Strains MN-005 and MN-006 were characterized using an extensive range of biochemical tests. The 16S ribosomal deoxyribonucleic acid (rDNA) sequence analysis was also performed for the two strains. Their naphthalene degradation capabilities were determined using gas chromatography and DAPI counting of bacterial cells. Strains MN-005 and MN-006 are phenotypically and phylogenetically different from each other, and belong to the genera Staphylococcus and Micrococcus, respectively. Strains MN-005 and MN-006 has maximal specific growth rates (μ max ) of 0.082±0.008 and 0.30±0.02 per hour, respectively, and half-saturation constants (K s ) of 0.79±0.10 and 2.52±0.32 mg per litre, respectively. These physiological and growth studies are useful in assessing the potential of these indigenous isolates for in situ or ex situ naphthalene pollutant bioremediation in tropical marine environments.

    Disparities between the health of Indigenous and non-Indigenous populations continue to be prevalent within Australia. Research suggests that Indigenous people participate in health risk behaviour more often than their non-Indigenous counterparts, and that such behaviour has a substantial impact on health outcomes. Although this would indicate that reducing health risk behaviour may have positive effects on health outcomes, the factors that influence Indigenous health behaviour are still poorly understood. This study aimed to interview people who support Indigenous groups to gain an understanding of their views on the factors influencing health behaviour within Indigenous groups in Western Australia. Twenty nine people participated in the study. The emergent themes were mapped against the social ecological model. The results indicated that: (1) culture, social networks, history, racism, socioeconomic disadvantage, and the psychological distress associated with some of these factors interact to affect health behaviour in a complex manner; (2) the desire to retain cultural identity and distinctiveness may have both positive and negative influence on health risk behaviour; (3) strong social connections to family and kin that is intensified by cultural obligations, appears to affirm and disrupt positive health behaviour; (4) the separation between Indigenous and non-Indigenous social connection/networks that appeared to be fostered by marginalisation and racism may influence the effect of social networks on health behaviour; and (5) communication between Indigenous and non-Indigenous people may be interrupted by distrust between the groups, which reduces the influence of some non-Indigenous sources on the health behaviour of Indigenous people.

    Aboriginal and Torres Strait Islander Australians (hereafter respectfully Indigenous Australians) claim that they have been over-researched without corresponding research benefit. This claim raises two questions. The first, which has been covered to some extent in the literature, is about what type(s) of research are likely to achieve benefits for Indigenous people. The second is how researchers report the impact of their research for Indigenous people. This systematic review of Indigenous health reviews addresses the second enquiry. Fourteen electronic databases were systematically searched for Indigenous health reviews which met eligibility criteria. Two reviewers assessed their characteristics and methodological rigour using an a priori protocol. Three research hypotheses were stated and tested: (1) reviews address Indigenous health priority needs; (2) reviews adopt best practice guidelines on research conduct and reporting in respect to methodological transparency and rigour, as well as acceptability and appropriateness of research implementation to Indigenous people; and (3) reviews explicitly report the incremental impacts of the included studies and translation of research. We argue that if review authors explicitly address each of these three hypotheses, then the impact of research for Indigenous peoples' health would be explicated. Seventy-six reviews were included; comprising 55 journal articles and 21 Australian Government commissioned evidence review reports. While reviews are gaining prominence and recognition in Indigenous health research and increasing in number, breadth and complexity, there is little reporting of the impact of health research for Indigenous people. This finding raises questions about the relevance of these reviews for Indigenous people, their impact on policy and practice and how reviews have been commissioned, reported and evaluated. The findings of our study serve two main purposes. First, we have identified knowledge and

    Full Text Available This article explores the ways in which (a Indigenous youth involved in an HIV intervention took up and reclaimed their cultures as a project of defining ‘self’, and (b how Indigenous ‘culture’ can be used as a tool for resistance, HIV prevention and health promotion. Data were drawn from the Taking Action Project: Using arts-based approaches to develop Aboriginal youth leadership in HIV prevention. ‘By youth, for youth’ HIV education and awareness workshops were facilitated in six Indigenous communities across Canada, incorporating traditional and contemporary art forms to explore how youth perceived the links between structural inequality and HIV vulnerability. Over 100 youth participated, with 70 partaking in individual interviews to reflect on their experiences at the workshops. Interviews were audio-recorded, transcribed verbatim and analysed using NVivo software. Indigenous youth understood culture as a complex construct that included reconnecting to land, body, history, community and ceremony. For many youth, being Aboriginal and participating in cultural activities was seen as important for intergenerational healing, empowerment, health and combatting HIV. Youth spoke excitedly of their attempts to reclaim their languages and cultures despite barriers. They also understood art as a medium for self-expression and as an important site of cultural evolution. Our project demonstrates that the incorporation of culture within health strategies is important for effective HIV prevention amongst Indigenous youth. Reclaiming Indigenous cultures, languages and ceremonies may help to nurture future generations, diminish cycles of victimisation and combat hopelessness by reconnecting youth to stories of resistance and survival.

    The current configuration of indigenous peoples' health in Brazil results from a complex historical trajectory, responsible for major delays for this population segment in the countrywide social advances seen in recent decades, particularly in the fields of health, education, housing, and sanitation. The main focus of this contribution is to review synthetically a selection of the main results of the First National Survey of Indigenous People's Health and Nutrition, conducted in the period 2008-2009, which visited 113 villages across the Brazil and interviewed 6,692 women and 6,128 children. Among the results, emphasis is given to the observed poor sanitation conditions in villages, high prevalence of chronic malnutrition, anemia, diarrhea, and acute respiratory infections in children, and the emergence of non-communicable chronic diseases in women. The scenario depicted by this survey requires urgent critical review of indigenous health policy in order to better meet the health needs of Brazil's indigenous population.

    The settlement of the land now known as Canada meant the erasure - sometimes from ignorance, often purposeful - of Indigenous place-names, and understandings of territory and associated obligations. The Canadian map with its three territories and ten provinces, electoral boundaries and districts, reflects boundaries that continue to fragment Indigenous nations and traditional lands. Each fragment adds institutional requirements and organizational complexities that Indigenous nations must engage with when attempting to realize the benefits taken for granted under the Canadian social contract.

    Indigenous Knowledge is important for Indigenous communities across the globe and for the advancement of our general scientific knowledge. In particular, Indigenous astronomical knowledge integrates many aspects of Indigenous Knowledge, including seasonal calendars, navigation, food economics, law, ceremony, and social structure. Capturing, managing, and disseminating this knowledge in the digital environment poses a number of challenges, which we aim to address using a collaborative project emerging between experts in the higher education, library, archive and industry sectors. Using Microsoft's WorldWide Telescope and Rich Interactive Narratives technologies, we propose to develop software, media design, and archival management solutions to allow Indigenous communities to share their astronomical knowledge with the world on their terms and in a culturally sensitive manner.

  5. Xpey’ Relational Environments: an analytic framework for conceptualizing Indigenous health equity

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Introduction: Both health equity research and Indigenous health research are driven by the goal of promoting equitable health outcomes among marginalized and underserved populations. However, the two fields often operate independently, without collaboration. As a result, Indigenous populations are underrepresented in health equity research relative to the disproportionate burden of health inequities they experience. In this methodological article, we present Xpey’ Relational Environments, an analytic framework that maps some of the barriers and facilitators to health equity for Indigenous peoples. Methods: Health equity research needs to include a focus on Indigenous populations and Indigenized methodologies, a shift that could fill gaps in knowledge with the potential to contribute to ‘closing the gap’ in Indigenous health. With this in mind, the Equity Lens in Public Health (ELPH research program adopted the Xpey’ Relational Environments framework to add a focus on Indigenous populations to our research on the prioritization and implementation of health equity. The analytic framework introduced an Indigenized health equity lens to our methodology, which facilitated the identification of social, structural and systemic determinants of Indigenous health. To test the framework, we conducted a pilot case study of one of British Columbia’s regional health authorities, which included a review of core policies and plans as well as interviews and focus groups with frontline staff, managers and senior executives. Conclusion: ELPH’s application of Xpey’ Relational Environments serves as an example of the analytic framework’s utility for exploring and conceptualizing Indigenous health equity in BC’s public health system. Future applications of the framework should be embedded in Indigenous research methodologies.

    Little is known of the appropriateness of existing gatekeeper suicide prevention programs for Indigenous communities. Despite the high rates of Indigenous suicide in Australia, especially among Indigenous youth, it is unclear how effective existing suicide prevention programs are in providing appropriate management of Indigenous people at risk of suicide. In-depth, semi-structured interviews and focus groups were conducted with Indigenous communities in rural and regional areas of Southern Queensland. Thematic analysis was performed on the gathered information. Existing programs were time-intensive and included content irrelevant to Indigenous people. There was inconsistency in the content and delivery of gatekeeper training. Programs were also not sustainable for rural and regional Indigenous communities. Appropriate programs should be practical, relevant, and sustainable across all Indigenous communities, with a focus on the social, emotional, cultural and spiritual underpinnings of community wellbeing. Programs need to be developed in thorough consultation with Indigenous communities. Indigenous-led suicide intervention training programs are needed to mitigate the increasing rates of suicide experienced by Indigenous peoples living in rural and remote locations.

    Hamilton, Marcus J.; Walker, Robert S.; Kesler, Dylan C.

    2014-04-01

    Lowland South America has long been a battle-ground between European colonization and indigenous survival. Initial waves of European colonization brought disease epidemics, slavery, and violence that had catastrophic impacts on indigenous cultures. In this paper we focus on the demography of 238 surviving populations in Brazil. We use longitudinal censuses from all known indigenous Brazilian societies to quantify three demographic metrics: 1) effects of European contact on indigenous populations; 2) empirical estimates of minimum viable population sizes; and 3) estimates of post-contact population growth rates. We use this information to conduct population viability analysis (PVA). Our results show that all surviving populations suffered extensive mortality during, and shortly after, contact. However, most surviving populations exhibit positive growth rates within the first decade post-contact. Our findings paint a positive demographic outlook for these indigenous populations, though long-term survival remains subject to powerful externalities, including politics, economics, and the pervasive illegal exploitation of indigenous lands.

    2017-12-01

    Full Text Available Indigenous territories are facing increasing pressures from numerous legal and illegal activities that are pushing commodity frontiers within their limits, frequently causing severe environmental degradation and threatening indigenous territorial rights and livelihoods. In Central and South America, after nearly three decades of participatory mapping projects, interest is mounting among indigenous peoples in the use of new technologies for community mapping and monitoring as a means of defense against such threats. Since 2014, several innovative projects have been developed and implemented in the region to demonstrate and train indigenous communities in the use of small drones for territorial mapping and monitoring. In this paper, we report on five projects carried out in Peru, Guyana, and Panama. For each one we describe the context, main objectives, positive outcomes, challenges faced, and opportunities ahead. Preliminary results are promising and have gained the interest of many indigenous societies who envision this technology as a powerful tool to protect their territories and strengthen their claims regarding specific environmental liabilities and justice issues. Based on the results presented here and a review of previous similar studies, we offer a critical discussion of some of the main opportunities and challenges that we foresee regarding the use of small drones for indigenous territorial mapping and monitoring. In addition, we elaborate on why a careful, well thought-out, and progressive adoption of drones by indigenous peoples may trigger grassroots innovations in ways conducive to greater environmental justice and sustainability.

  16. In Vitro Activities of Terbinafine against Cutaneous Isolates of Candida albicans and Other Pathogenic Yeasts

    Ryder, Neil S.; Wagner, Sonja; Leitner, Ingrid

    1998-01-01

    Terbinafine is active in vitro against a wide range of pathogenic fungi, including dermatophytes, molds, dimorphic fungi, and some yeasts, but earlier studies indicated that the drug had little activity against Candida albicans. In contrast, clinical studies have shown topical and oral terbinafine to be active in cutaneous candidiasis and Candida nail infections. In order to define the anti-Candida activity of terbinafine, we tested the drug against 350 fresh clinical isolates and additional strains by using a broth dilution assay standardized according to the guidelines of the National Committee for Clinical Laboratory Standards (NCCLS) M27-A assay. Terbinafine was found to have an MIC of 1 μg/ml for reference C. albicans strains. For 259 clinical isolates, the MIC at which 50% of the isolates are inhibited (MIC50) of terbinafine was 1 μg/ml (fluconazole, 0.5 μg/ml), and the MIC90 was 4 μg/ml (fluconazole, 1 μg/ml). Terbinafine was highly active against Candida parapsilosis (MIC90, 0.125 μg/ml) and showed potentially interesting activity against isolates of Candida dubliniensis, Candida guilliermondii, Candida humicola, and Candida lusitaniae. It was not active against the Candida glabrata, Candida krusei, and Candida tropicalis isolates in this assay. Cryptococcus laurentii and Cryptococcus neoformans were highly susceptible to terbinafine, with MICs of 0.06 to 0.25 μg/ml. The NCCLS macrodilution assay provides reproducible in vitro data for terbinafine against Candida and other yeasts. The MICs for C. albicans and C. parapsilosis are compatible with the known clinical efficacy of terbinafine in cutaneous infections, while the clinical relevance of its activities against the other species has yet to be determined.

    The Leaders in Indigenous Medical Education (LIME) Network aims to improve the quality and effectiveness of Indigenous health in medical education as well as best practice in the recruitment, retention, and graduation of Indigenous medical students. In this article we explore the utility of Etienne Wenger's "communities of practice" (CoP) concept in providing a theoretical framework to better understand the LIME Network as a form of social infrastructure to further knowledge and innovation in this important area of health care education reform. The Network operates across all medical schools in Australia and New Zealand. Utilizing a model of evaluation of communities of practice developed by Fung-Kee-Fung et al., we seek to analyze the outcomes of the LIME Network as a CoP and assess its approach and contribution to improving the implementation of Indigenous health in the medical curriculum and the graduation of Indigenous medical students. By reflecting on the Network through a community of practice lens, this article highlights the synthesis between the LIME Network and Wenger's theory and provides a framework with which to measure Network outputs. It also posits an opportunity to better capture the impact of Network activities into the future to ensure that it remains a relevant and sustainable entity.

    Intensive African catfish culture in tarpaulin pond was popular in Banyuwangi, Indonesia since the government supported the fisheries sector. Unfortunately, the failure of African catfish culture still occurred since the waste from fish metabolite process and feed residue decreased the water quality. Bacteria in the water could be the solution to increase the success rate of aquaculture by improving the water quality. This study purpose was to obtained indigenous bacteria in intensive aquaculture system of African catfish to improve water quality. This study successfully isolated bacteria contained with amylase, protease and lipase characteristic. Isolated bacteria in this study were identified as Pseudomonas pseudomallei (97.81%), Bacillus subtilis (95.81%) and Pseudomonas stutzeri (61.21%).

    In this descriptive study we investigated the genetic structure of 513 Mexican indigenous subjects grouped in 14 populations (Mixteca-Alta, Mixteca-Baja, Otomi, Purépecha, Tzeltal, Tarahumara, Huichol, Nahua-Atocpan, Nahua-Xochimilco, Nahua-Zitlala, Nahua-Chilacachapa, Nahua-Ixhuatlancillo, Nahua-Necoxtla, and Nahua-Coyolillo) based on mtDNA haplogroups. These communities are geographically and culturally isolated; parents and grandparents were born in the community. Our data show that 98.6% of the mtDNA was distributed in haplogroups A1, A2, B1, B2, C1, C2, D1, and D2. Haplotype X6 was present in the Tarahumara (1/53) and Huichol (3/15), and haplotype L was present in the Nahua-Coyolillo (3/38). The first two principal components accounted for 95.9% of the total variation in the sample. The mtDNA haplogroup frequencies in the Purépecha and Zitlala were intermediate to cluster 1 (Otomi, Nahua-Ixhuatlancillo, Nahua-Xochimilco, Mixteca-Baja, and Tzeltal) and cluster 2 (Nahua-Necoxtla, Nahua-Atocpan, and Nahua-Chilacachapa). The Huichol, Tarahumara, Mixteca-Alta, and Nahua-Coyolillo were separated from the rest of the populations. According to these findings, the distribution of mtDNA haplogroups found in Mexican indigenous groups is similar to other Amerindian haplogroups, except for the African haplogroup found in one population.

    Full Text Available Background and Objective: Probiotics have to reach their site of action in certain numbers in order to exhibit positive health effects. Encapsulation has shown remarkable enhancing effects on probiotic survival in simulated gastric conditions compared to free bacteria. The purpose of this study was identification and evaluation of a potential probiotic strain using encapsulation process by new carriers in order to improve probiotic viability during in vitro simulated conditions.Material and Methods: A native Lactobacillus was isolated from yogurt, identified as Lactobacillus casei PM01 (NCBI registered and analyzed for probiotic properties alongside established probiotic strains of Lactobacillus acidophilus ATCC 43556, and Lactobacillus rhamnosus ATCC 7469. Acid and bile resistance, adhesion to Caco-2 cells and antibiotic resistance were evaluated. Lactobacillus casei PM01 was encapsulated with alginate, chitosan and natural branched polysaccharides (pectin, tragacanth gum and gum Arabic by using extrusion technique. Encapsulation efficiency, acidification activity and viability of entrapped Lactobacillus casei PM01 in simulated gastric pH were determined. Results and Conclusion: Based on the results, all the three strains could be considered as potential probiotics, and are good candidates for further in vitro and in vivo evaluation. The results showed that the survival of encapsulated Lactobacillus casei PM01 was significantly (p≤0.05 increased when it was incubated in simulated gastric pH. It can be concluded that indigenous Lactobacillus casei PM01 in encapsulated form is introduced as an efficient probiotic strain for using in dairy products.Conflict of interest: The authors declare no conflict of interest.

    Respiratory diseases are a leading cause of morbidity and mortality in Indigenous Australians. However, there are limited approaches to specialist respiratory care in rural and remote communities that are culturally appropriate. A specialist Indigenous Respiratory Outreach Care (IROC) program, developed to address this gap, is described. The aim of the present study was to implement, pilot and evaluate multidisciplinary specialist respiratory outreach medical teams in rural and remote Indigenous communities in Queensland, Australia. Sites were identified based on a perception of unmet need, burden of respiratory disease and/or capacity to use the clinical service and capacity building for support offered. IROC commenced in March 2011 and, to date, has been implemented in 13 communities servicing a population of approximately 43000 Indigenous people. Clinical service delivery has been possible through community engagement and capacity building initiatives directed by community protocols. IROC is a culturally sensitive and sustainable model for adult and paediatric specialist outreach respiratory services that may be transferrable to Indigenous communities across Queensland and Australia.

    To detect and characterize broad-spectrum antipathogen activity of indigenous bacterial isolates obtained from potato soil and soya bean leaves for their potential to be developed as biofungicides to control soilborne diseases such as Fusarium crown and root rot of tomato (FCRR) caused by Fusarium oxysporum f. sp. radicis-lycopersici (Forl). Thirteen bacterial isolates (Bacillus amyloliquefaciens (four isolates), Paenibacillus polymyxa (three isolates), Pseudomonas chlororaphis (two isolates), Pseudomonas fluorescens (two isolates), Bacillus subtilis (one isolate) and Pseudomonas sp. (one isolate)) or their volatiles showed antagonistic activity against most of the 10 plant pathogens in plate assays. Cell-free culture filtrates (CF) of five isolates or 1-butanol extracts of CFs also inhibited the growth of most pathogen mycelia in plate assays. PCR analysis confirmed the presence of most antibiotic biosynthetic genes such as phlD, phzFA, prnD and pltC in most Pseudomonas isolates and bmyB, bacA, ituD, srfAA and fenD in most Bacillus isolates. These bacterial isolates varied in the production of hydrogen cyanide (HCN), siderophores, β-1,3-glucanases, chitinases, proteases, indole-3-acetic acid, salicylic acid, and for nitrogen fixation and phosphate solubilization. Gas chromatography-mass spectrometry analysis identified 10 volatile compounds from 10 isolates and 18 compounds from 1-butanol extracts of CFs of five isolates. Application of irradiated peat formulation of six isolates to tomato roots prior to transplanting in a Forl-infested potting mix and field soil provided protection of tomato plants from FCRR disease and enhanced plant growth under greenhouse conditions. Five of the 13 indigenous bacterial isolates were antagonistic to eight plant pathogens, both in vitro and in vivo. Antagonistic and plant-growth promotion activities of these isolates might be related to the production of several types of antibiotics, lytic enzymes, phytohormones, secondary

    Full Text Available This paper makes a case for harnessing indigenous knowledge (IK for sustainable national development in Ghana. IK according to the World Bank is the basic component of any country’s knowledge system and it is upon this knowledge that scientific research builds. In Ghana the Government has recognized the need to harness IK for sustainable national development and has therefore incorporated it into the National Science, Technology and Innovation Development Programme. But there is no evidence however that scientific research in Ghana actually takes IK into consideration during the research process. This paper discusses the concept of indigenous knowledge, its relevance in scientific discourse and the need for harnessing it for national development in Ghana. A desk study was conducted using journal publications, research and technical reports, online databases and the internet. About sixty articles were analysed using the thematic synthesis method under the following broad headings: Importance of Indigenous knowledge, Indigenous forest foods, Indigenous medicines, IK and food security, the management and processing of IK and the protection of Indigenous Knowledge.The results of the study established the need to document the local knowledge using appropriate procedures and strategies. It also concludes by suggesting that IK in Ghana must be protected by law and integrated into formal science.

    Trichomonas vaginalis, a flagellate protozoan, is the causative agent of trichomonosis, the most common nonviral sexually transmitted disease worldwide. Taking into account the increased prevalence of metronidazole-resistant isolates, alternative drugs are essential for the successful treatment. Natural products are the source of most new drugs, and popular wisdom about the use of medicinal plants is a powerful tool in this search. In this study, the activity of 10 medicinal plants extensively used in daily life by Mbyá-Guarani indigenous group was evaluated against seven different T. vaginalis isolates. Among the aqueous extracts tested, Verbena sp. (Guachu ka'a in Mbyá-Guarani language) and Campomanesia xanthocarpa (Guavira in Mbyá-Guarani language) showed the highest activity against T. vaginalis with MIC value of 4.0 mg/mL reaching 100% of efficacy against the parasite. The kinetic growth assays showed that the extracts promoted complete growth abolishment after 4 h of incubation. In addition, the extracts tested did not promote a significant hemolytic activity against human erythrocytes. Our results show for the first time the potential activity of Verbena sp. and C. xanthocarpa against T. vaginalis. In addition, this study demonstrates that indigenous knowledge is an important source of new prototype antiprotozoal agents.

    Cells of Candida guilliermondii permeabilized with Triton X-100 were able to efficiently produce xylitol from a medium composed only by D-xylose and MgCl 2 ·6H 2 O in potassium phosphate buffer, at 35 °C and pH 6.5. Under these conditions, the results were similar to those obtained when cofactor and co-substrate or nutrients were added to the medium (about 95 % D-xylose was assimilated producing 42 g/L of xylitol, corresponding to 0.80 g/g yield and 2.65 g/L h volumetric productivity). Furthermore, the permeabilized cells kept the D-xylose assimilation in about 90 % and the xylitol production in approx. 40 g/L during three bioconversion cycles of 16 h each. These values are highly relevant when compared to others reported in the literature using enzyme technology and fermentative process, thereby demonstrating the effectiveness of the proposed method. The present study reveals that the use of permeabilized cells is an interesting alternative to obtain high xylitol productivity using low cost medium formulation. This approach may allow the future development of xylitol production from xylose present in lignocellulosic biomass, with additional potential for implementation in biorefinery strategies.

    Full Text Available The identification of the fungal species belonging to the healthy microflora in animals is a precondition for the recognition of pathological processes causing them. The aim of this study was to investigate the presence of potentially pathogenic fungi in the feces of wild birds collected in Screening Centers. Samples were collected from the feces of 50 cages with different species of birds. The samples were processed according to the modified method STAIB and the plates incubated at 32 °C for up to ten days with daily observation for detection of fungal growth. The isolation of the following species was observed: Malassezia pachydermatis, Candida albicans, C. famata, C. guilliermondii, C. sphaerica, C. globosa, C. catenulata, C. ciferri, C. intermedia, Cryptococcus laurentii, Trichosporon asahii, Geotrichum klebahnii, Aspergillus spp., A. niger and Penicillium spp. Knowing the character of some opportunistic fungi is important in identifying them, facilitating the adoption of preventive measures, such as proper cleaning of cages, since the accumulation of excreta may indicate a risk for both health professionals and centers for screening public health.

    The poor health status of indigenous people has been identified internationally as a critical issue. It is now commonly accepted that the ability to address this concern is hindered, in part, by the disproportionately low number of indigenous health professionals, including nurses. This paper reports the findings of a review of literature that aimed to identify key barriers in the education of the indigenous undergraduate nursing students in the tertiary sector, to identify strategies to overcome these, and discuss these elements within the New Zealand context. A number of health-related databases were searched and a total of 16 peer-reviewed articles from Canada, U.S.A., Australia and New Zealand were reviewed. Key barriers to recruitment and retention and strategies to overcome these are presented. Barriers to recruitment included: academic unpreparedness; poor understanding of cultural needs; and conflicting obligations, and financial constraints. Barriers to retention included lack of cultural and academic support, family obligations and financial hardship. Strategies to address recruitment barriers included: addressing pre-entry education requirements; targeted promotion of nursing programmes; indigenous role models in the recruitment process; and streamlining enrolment processes to make programmes attractive and attainable for indigenous students. Strategies to address retention barriers included: cultural relevance within the curriculum; identifying and supporting cultural needs of indigenous students with active participation of indigenous staff; engaging communities and funding support. The crucial development of partnerships between academic institutes and indigenous communities to ensure the provision of a culturally safe, supportive environment for the students was stressed. In New Zealand, while government-level policy exists to promote the success of MBori nursing students, the translation of what is known about the recruitment and retention of

    Full Text Available Indigenous tourism is a relatively new concept for tourism stakeholders and has not become a priority to encourage local tourism potential. The lack of information and previous study about the concept of indigenous tourism and an understanding of the concept make tourism destination focused only in promoting local culture. Therefore, this research aims to identify: 1 the potential of Bitombang and Pandai Besi village in supporting indigenous tourism in Selayar Regency; 2 strategic steps required in supporting Selayar regency through indigenous tourism concept; and 3 actions to take for stakeholders to achieve development goals and achieving balance between indigenous tourism and sustainable tourism. Approach used in this study is feature of qualitative study which able to lead researcher in understanding indigenous tourism in Selayar Regency. To gather the data, researcher conducted interview to the society, government staff, and local communities in Selayar who possess adequate comprehension about the tourism circumstances, and Selayar people sociocultural condition. There are 8 choosen informants who are originally Selayar residents. The research shows that Bitombang and Pandai Besi Old Village are important assets in supporting the development of indigenous tourism, aside from another tourism potential. Therefore, study about history and cultural value of indigenous people, procurement of local tour guide, initiation from environmental organization, and travel route map for tourist are essential. Government’s role is also strongly expected to facilitate various communities to take part in the development of indigenous tourism.

    Health disparities exact a devastating toll upon Indigenous people in the USA. However, there has been scant research investment to develop strategies to address these inequities in Indigenous health. We present a case for increased health promotion, prevention, and treatment research with Indigenous populations, providing context to the recent NIH investment in the Intervention Research to Improve Native American Health (IRINAH) network. We discuss the disproportionate costs and consequences of disparities borne by Indigenous groups, the limited evidence base on effective intervention for this population, how population uniqueness often makes transfer of existing intervention models difficult, and additional challenges in creating interventions for Indigenous settings. Given the history of colonial disruption that has included genocide, forced removal from lands, damaging federal, state and local policies and practices, environmental contamination, and most recently, climate change, we conclude research that moves beyond minor transformations of existing majority population focused interventions, but instead truly respects Indigenous wisdom, knowledge, traditions, and aspirations is needed, and that investment in intervention science to address Indigenous health disparities represent a moral imperative.

    2013-10-01

    Socioeconomic and health disadvantage is widespread within and across indigenous communities in the world, leading to differentials in morbidity and mortality between indigenous and non-indigenous populations. Sexually transmitted infections (STIs), including HIV/AIDS, among indigenous populations are an emerging public health concern. The focus of this paper is on examining the STI epidemiology in indigenous communities in various parts of the world utilizing a range of data sources. Most of the STI research on global indigenous communities has concentrated on developed countries, neglecting more than half the world's indigenous people in the developing countries. This has resulted in major gaps in data at global level for STIs and HIV/AIDS among indigenous populations. Available data show that the prevalence of STIs is increasing among the indigenous communities and in several instances, the rates of these infections are higher than among non-indigenous populations. However, HIV still remains low when compared with the rates of other STIs. The paper argues that there is an urgent need to collect more comprehensive and reliable data at the global level across various indigenous communities. There is also an opportunity to reverse current trends in STIs through innovative, evidence-based and culturally appropriate targeted sexual health programmes.

    Catherine E. Burnette

    2014-09-01

    Full Text Available Background: Violence against indigenous women and girls is endemic, yet the absence of research on the consequences of this violence from the perspectives of women presents a profound barrier to the development of knowledge, along with violence prevention and mitigation. Although family is central to many indigenous communities, existing research typically examines the consequences of intimate partner violence (IPV on women or children in isolation, rather than examining its consequences holistically. Objective: The purpose of this article is to identify US indigenous women's perspectives about the impact of IPV on women, children, and families. Method: Data were collected with 29 indigenous women affected by violence from a Southeastern tribe in the United States. As part of a larger critical ethnography, pragmatic horizon analysis of life history interviews revealed the consequences of IPV across multiple levels. Results: Women reported profound psychological consequences resulting from IPV. The majority of women had witnessed IPV in their childhood, providing support for an intergenerational cycle of violence. Women reported psychological consequences on children, which paralleled those reported by women, leaving deep impressions on children across their life course. Consequences on children and whole families were extensive, indicating the negative ramifications of IPV transcended personal boundaries and affected children and families across multiple generations. Conclusions: Given the tight-knit nature of indigenous families and communities, the consequences across individuals and families were noteworthy. However, a dearth in research examining consequences of IPV across levels fails to capture the interconnections of consequences for women, children, and families. Given the centrality of family in many indigenous communities, examining IPV from a holistic perspective that incorporates multiple levels is recommended for IPV research and

It details the main events in the process of indigenous mobilisation in the form of three emblematic cases carried out on an interna­tional scale, together with their implications for the national political arena. The author explains how, after the indigenous people’s demands were blocked at home, they then mobilised abroad, where they raised aware­ness over their situation and called for justice in the international courts. Finally, at the local level the paper identifies the inclusion of glo­bal frameworks related to the human rights to the indigenous peoples.

    Salvia species have long been described in traditional medicine for various indications. Owing to the widespread use of this genus by ethnic populations, especially for various infections ranging from skin disease to gastrointestinal disorders, we were encouraged to determine whether Salvia rhytidea could be effective against fungal infections. Given the increased incidence of candidiasis in the past decade, limits on the use of antifungal drugs, emergence of azole-resistant Candida species and increased incidence of treatment failures, it is necessary to identify a novel agent with antifungal properties. Aim of the study was to evaluate the antifungal properties of S. rhytidea against various Candida isolates. In this study, at first rosmarinic acid content of plant extract was determined. A total of 96 Candida isolates were tested, including the following species: Candida albicans (n=42), Candida glabrata (n=16), Candida tropicalis (n=11), Candida krusei (n=9), Candida parapsilosis (n=9), Candida lusitaniae (n=7) and Candida guilliermondii (n=2). The in vitro antifungal activity of methanolic extracts of S. rhytidea Benth. was evaluated against Candida isolates and compared with that of the standard antifungal drug nystatin by using a broth microdilution method, according to CLSI. Phytochemical screening results showed that the methanolic extract of S. rhytidea Benth. was rich in flavonoids and tannins. The minimal inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values of S. rhytidea Benth. ranged from 3.125 to>100μg/ml and 6.25 to>100μg/ml respectively. The growth inhibition value displayed that C. tropicalis, C. krusei and C. albicans isolates were most susceptible to S. rhytidea. Findings show that S. rhytidea possesses an antifungal effect against Candida isolates. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Examine the relationship between maternal alcohol use disorder and child school attendance outcomes for non-Indigenous and Indigenous children in Western Australia. Population cohort study. Routinely collected linked administrative health, education and child protection data. Those in-scope for the study were women with a birth recorded on the Western Australian Midwives Notification System (1989-2007). Women who had an alcohol-related diagnosis (International Classification of Diseases Revisions 9/10) recorded on the Hospital Morbidity, Mental Health Inpatients and Outpatients, and Drug and Alcohol Office data sets formed the exposed group. The comparison cohort was frequency-matched to the exposed cohort based on maternal age within Indigenous status and child's year of birth. Child's school attendance was obtained from the Department of Education (2008-2012). Poor attendance was defined as alcohol use disorder was significantly associated with increased odds of poor attendance (non-Indigenous: OR=1.61, 95% CI 1.50 to 1.74; Indigenous: OR=1.66, 95% CI 1.54 to 1.79). With adjustment for maternal and child factors, there was no significant difference between the timing of alcohol diagnosis relative to pregnancy and attendance outcomes. The population attributable fraction was higher in the Indigenous cohort than the non-Indigenous cohort (6.0% vs 1.3%). Maternal alcohol use disorder was associated with a significantly increased odds of poor school attendance for non-Indigenous and Indigenous children. There was no significant difference between the timing of diagnoses and odds of poor school attendance. This suggests that the effect of maternal alcohol use disorder may not be driven by the neurodevelopmental effects of alcohol exposure in utero, but may be mediated through family or social factors for which we were unable to adjust. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  9. Gender Gaps in Indigenous Socioeconomic Outcomes: Australian Regional Comparisons and International Possibilities

    Directory of Open Access Journals (Sweden)

    2010-07-01

    Full Text Available International literature clearly demonstrates the potential for gender-based inequalities to constrain development processes. In the United Nations Development Programme Gender-related Development Index, Australia ranks in the top five across 177 countries, suggesting that the loss of human development due to gender inequality is minor. However, such analysis has not been systematically applied to the Indigenous Australian population, at least in a quantitative sense. Using the 2006 Australian Census, this paper provides an analysis across three dimensions of socioeconomic disparity: Indigeneity, gender, and geography. This paper also explores the development of a similar gender-related index as a tool to enable a relative ranking of the performance of Indigenous males and females at the regional level across a set of socioeconomic outcomes.The initial findings suggest that although there is a substantial development gap between Indigenous and non-Indigenous Australians, the development loss from gender-related inequality for Indigenous Australians is relatively small. Higher life expectancy and education attainment for Indigenous females balances out their slightly lower earnings to a large extent. At the regional level, Indigenous females tend to fare better than Indigenous males for the set of indicators chosen; and, this is particularly true in capital cities.

  10. Otitis media in Indigenous Australian children: review of epidemiology and risk factors.

    Otitis media represents a major health concern in Australian Indigenous children ('Indigenous children'), which has persisted, despite public health measures, for over 30 years. Global searches were performed to retrieve peer-reviewed and 'grey' literature investigating the epidemiology of and risk factors for otitis media in Indigenous children, published between 1985 and 2012. In Indigenous children, the prevalence of otitis media subtypes is 7.1-12.8 per cent for acute otitis media, 10.5-30.3 per cent for active chronic otitis media and 31-50 per cent for tympanic membrane perforation. The initial onset of otitis media in Indigenous children occurs earlier and persists for longer after the first year of life, compared with non-Indigenous children. Indigenous children are colonised by otopathogens more frequently, at younger ages and with a higher bacterial load. Poor community and domestic infrastructure, overcrowding and exposure to tobacco smoke increase the risk of otitis media in Indigenous children; however, the availability of swimming pools plays no role in the prevention or management of otitis media. Despite awareness of the epidemiological burden of otitis media and its risk factors in Indigenous children, studies undertaken since 1985 demonstrate that otitis media remains a significant public health concern in this population.

    Full Text Available Abstract Background In common with Indigenous populations elsewhere, Indigenous Australians have higher incidence of end-stage kidney disease (ESKD, but lower transplantation rates than their non-Indigenous counterparts. Understanding how the demands of dialysis impact on, and are impacted by, the lives of Indigenous patients may provide important insight into treatment pathways and decision-making. Methods We conducted semi-structured interviews in 2005–06 with 146 Indigenous and 95 non-Indigenous patients from nine hospital renal wards and 17 associated dialysis centres, which together treat the majority of Indigenous Australian ESKD patients. Results Factors influencing treatment experience included: the impacts of late diagnosis; family separations associated with relocating for treatment; the physical and psychosocial demands of hemodialysis; and ineffective communication between health care providers and patients. Although not unique to them, Indigenous patients were more likely to experience the combined effect of all factors. Conclusions Social/situational circumstances profoundly affect Indigenous Australian dialysis patients’ ability to fully engage with treatment. This may ultimately affect their likelihood of receiving optimal treatment, including transplantation. Areas for improvement include: earlier diagnosis; improved linkages between specialist renal services and primary care in regional settings; more effective communication and patient education; and more systematic, transparent approaches to patient “compliance” in transplant and home dialysis guidelines.

    Sumida Huaman, Elizabeth

    2016-12-01

    Based on ethnographic research with an Indigenous community in Junín, Peru, and involving over 21 participants, this article explores the link between Indigenous lands, environmental knowledge, cultural practices, and education. Drawing from traditional ecological knowledge and nature-mediated education, Indigenous community spaces as vital learning spaces are highlighted. Through the lens of family and community-scale farming, this article also discusses critical perspectives on Indigenous agricultural traditions, lessons in subsistence farming, food and notions of success for students, and globalisation. Finally, an argument is made for educational development to acknowledge the breadth of Indigenous ecological issues, to prioritize Indigenous lands, languages, and cultural practices, and to support collaborative research that underscores Indigenous epistemologies.

    Indigenous peoples are among the most marginalized peoples in the world due to issues relating to well-being, political representation, and economic production. The research consortium Goals and Governance for Global Health (Go4Health) conducted a community consultation process among marginalized groups across the global South aimed at including their voices in the global discourse around health in the post-2015 development agenda. This paper presents findings from the consultations carried out among indigenous communities in Bangladesh. For this qualitative study, our research team consulted the Tripura and Mro communities in Bandarban district living in the isolated Chittagong Hill Tracts region. Community members, leaders, and key informants working in health service delivery were interviewed. Data was analyzed using thematic analysis. Our findings show that remoteness shapes the daily lives of the communities, and their lack of access to natural resources and basic services prevents them from following health promotion messages. The communities feel that their needs are impossible to secure in a politically indifferent and sometimes hostile environment. Communities are keen to participate and work with duty bearers in creating the conditions that will lead to their improved quality of life. Clear policies that recognize the status of indigenous peoples are necessary in the Bangladeshi context to allow for the development of services and infrastructure.

    2018-02-01

    Full Text Available This article seeks to revisit dominant narratives of digital technological development in Indigenous communities in Canada. By prioritizing Indigenous voices and drawing from concepts of self-determination and sovereignty, this analysis reorients discourse surrounding the “digital divide” towards a strength-based approach that positions Indigenous peoples as innovators and creators, not just consumers, of digital technologies. This article begins with a discussion of how dominant media has used technology and technological imagery to misrepresent Indigenous cultures and perpetuate colonial biases, and emphasizes the importance of making space for Indigenous future imagery. Following this is a discussion of digital storytelling and virtual landscapes, showcasing a small sample of Indigenous initiatives online, in video game and app development, and in augmented and virtual reality. Finally, this article considers the potential of “makerspaces” as a framework for future action to bridge theory and practice.

    2015-01-01

    Full Text Available Today the claims of Abya Yala’s indigenous and aboriginal women are positioned within Latin American’s indigenous agenda. Their participation in the indigenous movement and their own organizational processes as women led to the Continental Indigenous Women’s Summit Meeting of Abya Yala (Cumbre Continental de Mujeres Indígenas del Abya Yala, CCMI which has been held twice in the region in 2009 in Puno Peru and in 2013 in La María Piendamó Colombia. In this paper, we analyze the processes of emergence, articulation, consolidation and integration challenges of Abya Yala’s indigenous and aboriginal women into the Continental Indigenous Women’s Summit Meeting of Abya Yala, a successful process of constructing networks and solidarities. Through these summits, the specific claims of indigenous women have reached the international indigenous agenda, feminist and women’s movements, promoting their organization and empowerment. As observers in the second summit meeting and analyzing existing literature, we examine the actors that favored the process of emergence, how the first and second summit meetings were held, and debates and selection of the topics. We also discuss indigenous women’s relationship with feminism which influenced in some way or the other the processes that led to the summit meetings. Finally, we address the challenges of this organizational space of empowerment managed and constituted by indigenous and aboriginal women of the continent.

    Phytate is known as a strong chelate of minerals causing their reduced uptake by the human intestine. Ninety-three yeast isolates from traditional African fermented food products, belonging to nine species (Pichia kudriavzevii, Saccharomyces cerevisiae, Clavispora lusitaniae, Kluyveromyces marxianus, Millerozyma farinosa, Candida glabrata, Wickerhamomyces anomalus, Hanseniaspora guilliermondii and Debaryomyces nepalensis) were screened for phytase production on solid and liquid media. 95% were able to grow in the presence of phytate as sole phosphate source, P. kudriavzevii being the best growing species. A phytase coding gene of P. kudriavzevii (PHYPk) was identified and its expression was studied during growth by RT-qPCR. The expression level of PHYPk was significantly higher in phytate-medium, compared to phosphate-medium. In phytate-medium expression was seen in the lag phase. Significant differences in gene expression were detected among the strains as well as between the media. A correlation was found between the PHYPk expression and phytase extracellular activity.

    Full Text Available Illegal gold mining and the resulting gold mine tailing ponds on Buru Island in Maluku, Indonesia have increased Mercury (Hg levels in agricultural soil and caused massive environmental damage. High levels of Hg in soil lowers plant productivity and threatens the equilibrium of the food web. One possible method of handling Hg-contaminated soils is through bioremediation, which could eliminate Hg from the rhizosphere (root zone. In this study, indigenous fungi isolated from Hg-contaminated soil exhibited Hg-resistance in vitro. Soil samples were collected from the rhizosphere of pioneer plants which grew naturally in areas contaminated with gold mine tailing. The fungi’s capacity for Hg-resistance was confirmed by their better growth in chloramphenicol-boosted potato dextrose agar media which contained various HgCl2 concentrations. Four isolates exhibited resistance of up to 25 mg kg−1 of Hg, and in an experiment with young Chinese cabbage (Brassica rapa L. test plants, two fungi species (including Aspergillus were demonstrated to increase the soil’s availability of Hg. The results suggest that Hg-resistant indigenous fungi can mobilize mercury in the soil and serve as potential bioremediation agents for contaminated agricultural land.

    The obtained chitosan from shrimp shells waste used in the present work is compared with a standard chitosan. Six strains of the isolated fungi had the ability to attack the chitin namely: Candida tropicalis, Zygosaccharomyces rouxii, Candida guilliermondii, Trichoderma viride, Penicillium chrysogenum and Aspergillus niger. Z. rouxii and A. niger were the most active strains for decomposing chitin. The best culture conditions for chitosan production by the selected strains differed from one to another. Highest yield of chitosan was obtained after 96 h of incubation by A. niger (40.00 mg/g) in the basal medium followed by P. chrysogenum (38.20 mg/g). Optimum ph for chitosan production by C. tropicalis, Z. rouxii and T. viride was found to be 5.5, while ph 6.0 was the best for A. niger and C. guilliermondii. Meanwhile ph 5.0 was preferable for P. chrysogenllm. Regarding the carbon source, fructose as a sole carbon source in the medium was the best one for A. niger (92.58 mg/g) and T. viride (85.78 mg/g). C. tropicalis and Z. rouxii showed the highest chitosan production in the presence of sucrose (66.00 and 60.00 mg/g), whereas xylose was the best carbon for P. chrysogenum (62.50 mg/g). The selected strains were also differing in their nitrogen source requiring for production of chitosan. The present work confirmed that chitosan production by microorganisms is strongly dependent on the ph of the culture medium. The present data show that exposing the selected fungal strains to very low dose levels of gamma ray enhanced their productivity of chitosan and dry weight. The best environmental conditions of temperature degree, ph value and colloidal chitin concentration on chitinase activity produced by Z. rouxii were 30 degree C, 5.5 and 2% respectively, while they were 30 degree C, 6.0 and 1.5% for chitinase produced by A. niger in the same manner respectively

    2005-10-01

    Marginalization may affect health care delivery. Ways in which indigenous women experienced marginalization were examined. Data from 57 indigenous women (18 to 65 years) were analyzed for themes. Three themes emerged: historical trauma as lived marginalization, biculturalism experienced as marginalization, and interacting within a complex health care system. Experienced marginalization reflected participants' unique perspective and were congruent with previous research. It is necessary for health care providers to assess the detrimental impact of marginalization on the health status of individuals and/or communities.

    Individual caprine milk with different somatic cell counts (SCC) were studied with the aim of investigating the percentage distribution of leukocyte cell types and the activities of indigenous proteolytic enzymes; proteolysis of casein was also studied in relation to cell type following recovery from milk. The experiment was conducted on 5 intensively managed dairy flocks of Garganica goats; on the basis of SCC, the experimental groups were denoted low (L-SCC; 1,501,000 cells/mL) SCC. Leukocyte distribution differed between groups; polymorphonuclear neutrophilic leukocytes were higher in M-SCC and H-SCC milk samples, the percentage macrophages was the highest in H-SCC, and levels of nonviable cells significantly decreased with increasing SCC. Activities of all the main proteolytic enzymes were affected by SCC; plasmin activity was the highest in H-SCC milk and the lowest in L-SCC, and elastase and cathepsin D activities were the highest in M-SCC. Somatic cell count influenced casein hydrolysis patterns, with less intact α- and β-casein in H-SCC milk. Higher levels of low electrophoretic mobility peptides were detected in sodium caseinate incubated with leukocytes isolated from L-SCC milk, independent of cell type, whereas among cells recovered from M-SCC milk, macrophages yielded the highest levels of low electrophoretic mobility peptides from sodium caseinate. The level of high electrophoretic mobility peptides was higher in sodium caseinate incubated with polymorphonuclear neutrophilic leukocytes and macrophages isolated from M-SCC, whereas the same fraction of peptides was always the highest, independent of leukocyte type, for cells recovered from H-SCC milk. In caprine milk, a level of 700,000 cells/mL represented the threshold for changes in leukocyte distribution, which is presumably related to the immune status of the mammary gland. Differences in the profile of indigenous lysosomal proteolytic enzymes in caprine milk may influence the integrity of casein

  3. Alternative Perspectives on Sustainability: Indigenous Knowledge and Methodologies

    2017-02-01

    Full Text Available Indigenous knowledge (IK is now recognized as being critical to the development of effective, equitable and meaningful strategies to address socio-ecological crises. However efforts to integrate IK and Western science frequently encounter difficulties due to different systems of knowledge production and underlying worldviews. New approaches are needed so that sustainability can progress on the terms that matter the most for the people involved. In this paper we discuss a case study from Aotearoa New Zealand where an indigenous community is in the process of renegotiating and enacting new indigenous-led approaches to address coupled socio-ecological crises. We reflect on novel methodological approaches that highlight the ways in which projects/knowledge are co-produced by a multiplicity of human and non-human actors. To this end we draw on conceptualizations of environmental ethics offered by indigenous scholars and propose alternative bodies of thought, methods, and practices that can support the wider sustainability agenda.

    The present study reports evaluation of an indigenous microalgal isolate Chlorella sp. FC2 IITG as a potential candidate for biodiesel production. Characterization of the strain was performed under photoautotrophic, heterotrophic, and mixotrophic cultivation conditions. Further, an open-pond cultivation of the strain under outdoor conditions was demonstrated to evaluate growth performance and lipid productivity under fluctuating environmental parameters and in the presence of potential contaminants. The key findings were: (1) the difference in cultivation conditions resulted in significant variation in the biomass productivity (73-114 mg l⁻¹ day⁻¹) and total lipid productivity (35.02-50.42 mg l⁻¹ day⁻¹) of the strain; (2) nitrate and phosphate starvation were found to be the triggers for lipid accumulation in the cell mass; (3) open-pond cultivation of the strain under outdoor conditions resulted in biomass productivity of 44 mg l⁻¹ day⁻¹ and total lipid productivity of 10.7 mg l⁻¹ day⁻¹; (4) a maximum detectable bacterial contamination of 7 % of the total number of cells was recorded in an open-pond system; and (5) fatty acid profiling revealed abundance of palmitic acid (C16:0), oleic acid (C18:1) and linoleic acid (C18:2), which are considered to be the key elements for suitable quality biodiesel.

Leaders of the Indigenous Peoples' case studies, their communities and their academic partners. Reported strategies on how to improve use of local food systems in case study communities of Indigenous Peoples. Indigenous Peoples' reflections on their local food systems should be encouraged and acted upon to protect and promote sustainability of the cultures and ecosystems that derive their food systems. Promoting use of local traditional food biodiversity is an essential driver of food system sustainability for Indigenous Peoples, and contributes to global consciousness for protecting food biodiversity and food system sustainability more broadly. Key lessons learned, key messages and good practices for nutrition and public health practitioners and policy makers are given.

  8. "We have always lived here": indigenous movements, citizenship and poverty in Argentina.

    Science.gov (United States)

    vom Hau, Matthias; Wilde, Guillermo

    2010-01-01

    This article explores the nexus between indigenous mobilisation, citizenship, and poverty in Argentina. A subnational comparison of land struggles among the Diaguita Calchaqu in Tucumn and the Mbya Guaran in Misiones shows that changing global and national opportunity structures, most prominently a new multicultural citizenship regime, set the stage for indigenous mobilisation. In turn, local transformations of capitalist development motivate indigenous mobilising efforts, whereas leadership patterns and state-movement relations shape the capacity to mobilise. Diaguita and Mbya mobilisation reveals that indigenous movements play a central role in the activation of formal citizenship rights and the contestation of dominant notions of poverty. At the same time, the current design of multicultural citizenship and the adverse socioeconomic incorporation of indigenous communities also counteract indigenous mobilising efforts in Argentina.

    Maternal and newborn health disparities and the health impacts of climate change present grand challenges for global health equity, and there remain knowledge gaps in our understanding of how these challenges intersect. This study examines the pathways through which mothers are affected by seasonal and meteorological factors in sub-Saharan Africa in general, and Kanungu District (Uganda), in particular. We conducted a community-based study consisting of focus group discussions with mothers and interviews with health care workers in Kanungu District. Using a priori and a posteriori coding, we found a diversity of perspectives on the impacts of seasonal and weather exposures, with reporting of more food available in the rainy season. The rainy season was also identified as the period in which women performed physical labour for longer time periods, while work conditions in the dry season were reported to be more difficult due to heat. The causal pathways through which weather and seasonality may be affecting size at birth as reported by Kanungu mothers were consistent with those most frequently reported in the literature elsewhere, including maternal energy balance (nutritional intake and physical exertion output) and seasonal illness. While both Indigenous and non-Indigenous mothers described similar pathways, however, the severity of these experiences differed. Non-Indigenous mothers frequently relied on livestock assets or opportunities for less taxing physical work than Indigenous women, who had fewer options when facing food shortages or transport costs. Findings point to specific entry points for intervention including increased nutritional support in dry season periods of food scarcity, increased diversification of wage labour opportunities, and increased access to contraception. Interventions should be particularly targeted towards Indigenous mothers as they face greater food insecurity, may have fewer sources of income, and face greater overall deprivation

    Full Text Available This paper focuses upon a place called the Vertical Village, a building in the center of Rio de Janeiro inhabited exclusively by indigenous peoples from different ethnic groups belonging to different parts of the country. In this paper, we discuss questions related to the experience of being indigenous in a city, the construction of a residential space as a village, and the constitution of indigenous identity in the urban context. Following the paths of three inhabitants of the building, the questions considered emerge from their transiting between cities and villages, frontiers either real or imaginary, prejudices and expectations of indigenous identity.

  16. The Problem of Scale in Indigenous Knowledge: a Perspective from Northern Australia

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available Over the last decade, indigenous knowledge has been widely touted by researchers and natural resource managers as a valuable contributor to natural resource management and biodiversity conservation. In Australia, the concept of indigenous knowledge has gained such rapid currency that it has tended toward an essentialized and universal truth rather than remaining a diverse range of highly localized and contested knowledge. In this paper, I undertake a critical analysis of some of the current issues around the interpretation and application of indigenous knowledge and its relationship with natural resource management in northern Australia. Through a focus on how indigenous knowledge operates at a range of scales, I argue that indigenous knowledge is not adapted to the scales and kinds of disturbances that contemporary society is exerting on natural systems. Rather than being realistic about the limitations of indigenous knowledge, I argue that nonindigenous interpretations of indigenous knowledge have propelled us toward reified meanings, abstracted concepts, and an information-based taxonomy of place. The result can be the diminishing and ossifying of a dynamic living practice and the failure to recognize expressions of indigeneity in contemporary forms.

    The prairie provinces of Canada. To characterize tuberculosis (TB) transmission among the Indigenous and non-Indigenous Canadian-born peoples of the prairie provinces of Canada. A prospective epidemiologic study of consecutively diagnosed adult (age ≥ 14 years) Canadian-born culture-positive pulmonary TB cases on the prairies, hereafter termed "potential transmitters," and the transmission events generated by them. "Transmission events" included new positive tuberculin skin tests (TSTs), TST conversions, and secondary cases among contacts. In the years 2007 and 2008, 222 potential transmitters were diagnosed on the prairies. Of these, the vast majority (198; 89.2%) were Indigenous peoples who resided in either an Indigenous community (135; 68.2%) or a major metropolitan area (44; 22.2%). Over the 4.5-year period between July 1st, 2006 and December 31st 2010, 1085 transmission events occurred in connection with these potential transmitters. Most of these transmission events were attributable to potential transmitters who identified as Indigenous (94.5%). With a few notable exceptions most transmitters and their infected contacts resided in the same community type. In multivariate models positive smear status and a higher number of close contacts were associated with increased transmission; adjusted odds ratios (ORs) and 95% confidence intervals (CIs), 4.30 [1.88, 9.84] and 2.88 [1.31, 6.34], respectively. Among infected contacts, being Indigenous was associated with disease progression; OR and 95% CI, 3.59 [1.27, 10.14] and 6.89 [2.04, 23.25] depending upon Indigenous group, while being an infected casual contact was less likely than being a close contact to be associated with disease progression, 0.66 [0.44, 1.00]. In the prairie provinces of Canada and among Canadian-born persons, Indigenous peoples account for the vast majority of cases with the potential to transmit as well as the vast majority of infected contacts.

    Full Text Available The Ontario Ministry of Education has declared a commitment to Indigenous student success and has advanced a policy framework that articulates inclusion of Indigenous content in schooling curriculum (Ontario Ministry of Education, 2007. What are the perceptions among educators and parents regarding the implementation of policy directives, and what is seen to encourage or limit meaningful implementation? To answer these questions, this article draws on interviews with 100 Indigenous (mainly Haudenosaunee, Anishinaabe, and Métis and non-Indigenous parents and educators from Ontario Canada. Policy directives are seen to benefit Indigenous and non-Indigenous students. Interviews also reveal challenges to implementing Indigenous curricular policy, such as unawareness and intimidation among non-Indigenous educators regarding how to teach material. Policy implications are considered.

    2016-09-01

    Full Text Available The citizen science program to supplement authoritative data in tree inventory has been well implemented in various countries. However, there is a lack of study that assesses correctness and accuracy of tree data supplied by citizens. This paper addresses the issue of tree data quality supplied by semi-literate indigenous group. The aim of this paper is to assess the correctness of attributes (tree species name, height and diameter at breast height and the accuracy of tree horizontal positioning data supplied by indigenous people. The accuracy of the tree horizontal position recorded by GNSS-enable smart phone was found to have a RMSE value of ± 8m which is not suitable to accurately locate individual tree position in tropical rainforest such as the Royal Belum State Park. Consequently, the tree species names contributed by indigenous people were only 20 to 30 percent correct as compared with the reference data. However, the combination of indigenous respondents comprising of different ages, experience and knowledge working in a group influence less attribute error in data entry and increase the use of free text rather than audio methods. The indigenous community has a big potential to engage with scientific study due to their local knowledge with the research area, however intensive training must be given to empower their skills and several challenges need to be addressed.

    Indigenous populations have poorer health outcomes compared to their non-Indigenous counterparts. The evolution of Indigenous primary health care services arose from mainstream health services being unable to adequately meet the needs of Indigenous communities and Indigenous peoples often being excluded and marginalised from mainstream health services. Part of the solution has been to establish Indigenous specific primary health care services, for and managed by Indigenous peoples. There are a number of reasons why Indigenous primary health care services are more likely than mainstream services to improve the health of Indigenous communities. Their success is partly due to the fact that they often provide comprehensive programs that incorporate treatment and management, prevention and health promotion, as well as addressing the social determinants of health. However, there are gaps in the evidence base including the characteristics that contribute to the success of Indigenous primary health care services in providing comprehensive primary health care. This systematic scoping review aims to identify the characteristics of Indigenous primary health care service delivery models. This systematic scoping review was led by an Aboriginal researcher, using the Joanna Briggs Institute Scoping Review Methodology. All published peer-reviewed and grey literature indexed in PubMed, EBSCO CINAHL, Embase, Informit, Mednar, and Trove databases from September 1978 to May 2015 were reviewed for inclusion. Studies were included if they describe the characteristics of service delivery models implemented within an Indigenous primary health care service. Sixty-two studies met the inclusion criteria. Data were extracted and then thematically analysed to identify the characteristics of Indigenous PHC service delivery models. Culture was the most prominent characteristic underpinning all of the other seven characteristics which were identified - accessible health services, community

  7. Age standardisation – an indigenous standard?

    Directory of Open Access Journals (Sweden)

    Simmonds Shirley

    2007-05-01

    Full Text Available Abstract The study of inequities in health is a critical component of monitoring government obligations to uphold the rights of Indigenous Peoples. In Aotearoa/New Zealand the indigenous Māori population has a substantially younger age structure than the non-indigenous population making it necessary to account for age differences when comparing population health outcomes. An age-standardised rate is a summary measure of a rate that a population would have if it had a standard age structure. Changing age standards have stimulated interest in the potential impact of population standards on disparities data and consequently on health policy. This paper compares the age structure of the Māori and non-Māori populations with two standard populations commonly used in New Zealand: Segi's world and WHO world populations. The performance of these standards in Māori and non-Māori mortality data was then measured against the use of the Māori population as a standard. It was found that the choice of population standard affects the magnitude of mortality rates, rate ratios and rate differences, the relative ranking of causes of death, and the relative width of confidence intervals. This in turn will affect the monitoring of trends in health outcomes and health policy decision-making. It is concluded that the choice of age standard has political implications and the development and utilisation of an international indigenous population standard should be considered.

    The use of PCR-RFLP analysis as a useful microbial identification tool has been evaluated for years. This approach was verified effective worldwide, where differential DNA bands and sequence markers distinctive to specific microbes or microbial groups have been identified. In our study, PCR-RFLP technique has been adopted in the identification of our indigenous N 2 -fixing isolates obtained from several local environments. RFLP was carried out with suitable restriction enzymes and the patterns were documented. Representatives of the different patterns were selected and analysed with the 16S ribosomal DNA sequencing method. The results demonstrated correlation between the differential RFLP patterns and the 16S rDNA identities. (Author)

    Indigenous young people have significantly higher suicide rates than their non-indigenous counterparts. There is a need for culturally appropriate and effective suicide prevention programs for this demographic. This review assesses suicide prevention programs that have been evaluated for indigenous youth in Australia, Canada, New Zealand, and the United States. The databases MEDLINE and PsycINFO were searched for publications on suicide prevention programs targeting indigenous youth that include reports on evaluations and outcomes. Program content, indigenous involvement, evaluation design, program implementation, and outcomes were assessed for each article. The search yielded 229 articles; 90 abstracts were assessed, and 11 articles describing nine programs were reviewed. Two Australian programs and seven American programs were included. Programs were culturally tailored, flexible, and incorporated multiple-levels of prevention. No randomized controlled trials were found, and many programs employed ad hoc evaluations, poor program description, and no process evaluation. Despite culturally appropriate content, the results of the review indicate that more controlled study designs using planned evaluations and valid outcome measures are needed in research on indigenous youth suicide prevention. Such changes may positively influence the future of research on indigenous youth suicide prevention as the outcomes and efficacy will be more reliable.

    Older Indigenous adults encounter multiple challenges as their age intersects with health inequities. Research suggests that a majority of older Indigenous adults prefer to age in place, and they will need culturally safe assistive technologies to do so. The aim of this critical review was to examine literature concerning use, adaptation, and development of assistive technologies for health purposes by Indigenous peoples. Working within Indigenous research methodologies and from a decolonizing approach, searches of peer-reviewed academic and gray literature dated to February 2016 were conducted using keywords related to assistive technology and Indigenous peoples. Sources were reviewed and coded thematically. Of the 34 sources captured, only 2 concerned technology specifically for older Indigenous adults. Studies detailing technology with Indigenous populations of all ages originated primarily from Canada (n=12), Australia (n=10), and the United States (n=9) and were coded to four themes: meaningful user involvement and community-based processes in development, the digital divide, Indigenous innovation in technology, and health technology needs as holistic and interdependent. A key finding is the necessity of meaningful user involvement in technology development, especially in communities struggling with the digital divide. In spite of, or perhaps because of this divide, Indigenous communities are enthusiastically adapting mobile technologies to suit their needs in creative, culturally specific ways. This enthusiasm and creativity, coupled with the extensive experience many Indigenous communities have with telehealth technologies, presents opportunity for meaningful, culturally safe development processes. ©Louise Jones, Kristen Jacklin, Megan E O'Connell.

    Indigenous Australians experience profound levels of disadvantage in health, living standards, life expectancy, education and employment, particularly in comparison with non-Indigenous Australians. Very little information is available about the healthy development of Australian Indigenous children; the Longitudinal Study of Indigenous Children (LSIC) is designed to fill this knowledge gap.This dataset provides an opportunity to follow the development of up to 1759 Indigenous children. LSIC conducts annual face-to-face interviews with children (aged 0.5-2 and 3.5-5 years at baseline in 2008) and their caregivers. This represents between 5% and 10% of the total population of Indigenous children in these age groups, including families of varied socioeconomic and cultural backgrounds. Study topics include: the physical, social and emotional well-being of children and their caregivers; language; culture; parenting; and early childhood education.LSIC is a shared resource, formed in partnership with communities; its data are readily accessible through the Australian Government Department of Social Services (see http://dss.gov.au/lsic for data and access arrangements). As one of very few longitudinal studies of Indigenous children, and the only national one, LSIC will enable an understanding of Indigenous children from a wide range of environments and cultures. Findings from LSIC form part of a growing infrastructure from which to understand Indigenous child health. © The Author 2014.

    This study investigates biomechanical implications of walking with indigenous "Kolhapuri" footwear compared to barefoot walking among a population of South Indians. Ten healthy adults from South India walked barefoot and indigenously shod at voluntary speed on an artificial substrate. The experiment was repeated outside, on a natural substrate. Data were collected from (1) a heel-mounted 3D-accelerometer recording peak impact at heel contact, (2) an ankle-mounted 3D-goniometer (plantar/dorsiflexion and inversion/eversion), and (3) sEMG electrodes at the m. tibialis anterior and the m. gastrocnemius medialis. Data show that the effect of indigenous footwear on the measured variables, compared to barefoot walking, is relatively small and consistent between substrates (even though subjects walked faster on the natural substrate). Walking barefoot, compared to shod walking yields higher impact accelerations, but the differences are small and only significant for the artificial substrate. The main rotations of the ankle joint are mostly similar between conditions. Only the shod condition shows a faster ankle rotation over the rapid eversion motion on the natural substrate. Maximal dorsiflexion in late stance differs between the footwear conditions on an artificial substrate, with the shod condition involving a less dorsiflexed ankle, and the plantar flexion at toe-off is more extreme when shod. Overall the activity pattern of the external foot muscles is similar. The indigenous footwear studied (Kolhapuri) seems to alter foot biomechanics only in a subtle way. While offering some degree of protection, walking in this type of footwear resembles barefoot gait and this type of indigenous footwear might be considered "minimal". © 2017 The Authors American Journal of Physical Anthropology Published by Wiley Periodicals, Inc.

    Full Text Available Climate change has direct and indirect consequences for individuals and their human rights (McInerney-Lankford et al. 2011. With the Arctic warming at twice the global rate, its inhabitants already experience many of these challenges. Marginalized groups, like women and indigenous peoples, are particularly vulnerable, with existing research providing evidence of ongoing and potential threats to their roles in community adaptation and in shaping change (Cameron 2011, Arctic Resilience Report 2016. While women’s rights are formally codified as human rights under the Convention on the Elimination of Discrimination against Women (CEDAW, and indigenous peoples’ human rights are codified and recognized in the UN Declaration on the Rights of Indigenous Peoples (UNDRIP, indigenous women’s rights are often neglected at both the international and local level. In this article, we apply an intersectional lens to demonstrate that indigenous and non-indigenous women are agents of change. In doing so, we examine how a human rights based approach might ensure indigenous women’s participatory role and legal status in the international climate change regime, as well as its related programs.

    Full Text Available Abstract Background The objective was to examine how the indigenous naming, indigenous self-diagnosis and management of diabetes evolved with awareness in order to develop a socially oriented theoretical model for its care. Methods The data was collected through a one-year extended participant observation in Bafut, a rural health district of Cameroon. The sample consisted of 72 participants in a rural health district of Cameroon (men and women with type 2 diabetes. We used participant observation to collect data through focus group discussions, in depth interviews and fieldwork conversations. The method of analysis entailed a thick description, thematic analysis entailing constant comparison within and across FGD and across individual participants and content analysis. Results The core concepts identified were the evolution of names for diabetes and the indigenous diagnostic and self-management procedures. Participants fell into one of two naming typologies: (a Naming excluding any signs and symptoms of diabetes; (b naming including signs and symptoms of diabetes. Participants fell into two typologies of diagnostic procedures: (a those that use indigenous diagnostic procedures for monitoring and controlling diabetes outcomes and b those that had initially used it only for diagnosis and continued to use them for self management. These typologies varied according to how participants' awareness evolved and the impact on self-diagnosis and management. Conclusion The evolution of names for diabetes was an important factor that influenced the subsequent self-diagnosis and management of diabetes in both traditional and modern biomedical settings.

  18. Understanding Public Support for Indigenous Natural Resource Management in Northern Australia

    Kerstin K. Zander

    2013-03-01

    Full Text Available Increased interest in indigenous-led natural resource management (NRM on traditionally owned land in northern Australia has raised important questions in relation to policies that compensate indigenous Australians for providing environmental services. A choice experiment survey was mailed out to respondents across the whole of Australia to assess if and to what extent Australian people think that society benefits from these services and how much they would pay for them. More than half the respondents would in principle support indigenous NRM in northern Australia, with a high willingness to pay for carbon, biodiversity, and recreational services. Social aspects of indigenous NRM, however, were not valued by the society, emphasizing the need for awareness raising and clarifications of benefits that indigenous people gain while carrying out land management on their traditional country. Any marketing campaign should take into account preference variation across Australian society, which this research shows is substantial, particularly between people from the north and those from the south. People from the south were more likely to support indigenous NRM, a significant finding for campaigns targeting potential donors.

    There is a growing body of research linking urban transport systems to inequities in health. However, there is a lack of research providing evidence of the effect of transport systems on indigenous family wellbeing. We examined the connections between urban transport and the health and wellbeing of Māori, the indigenous people of New Zealand. We provide an indigenous exploration of current urban transport systems, with a particular focus on the impacts of car dependence and the need for culturally relevant travel. We interviewed nineteen Māori participants utilising qualitative research techniques underpinned by an indigenous research methodology (Kaupapa Māori). The data highlighted the importance of accessing cultural activities and sites relevant to 'being Māori', and issues with affordability and safety of public transport. Understanding the relationship between indigenous wellbeing and transport systems that goes further than limited discourses of inequity is essential to improving transport for indigenous wellbeing. Providing an indigenous voice in transport decision-making will make it more likely that indigenous health and wellbeing is prioritised in transport planning. Copyright © 2013.

    Full Text Available The article presents a statistical review of the educational situation of the indigenous people in Mexico. For this reason, it is dissected if the subsystem of indigenous education meets the 4-A criteria. According to the United Nations’ Committee for Educational, Social and Cultural Rights, indigenous education should be available, accessible, acceptable and adaptable. (1999, General Comment no. 13 The aim of the review is to describe the status quo and to visualize duties for institutions and key actors from the field of indigenous as well as intercultural and bilingual education in México. The statistical review of the Mexican case showed that the criteria of a 4-A education for the indigenous Mexicans are not fulfilled. Indigenous education misses to be available due to the fact that the educational subsystem receives much less financial resources than the general educational system and counts with a lower standard of infrastructure. Furthermore, the indigenous education is no sufficiently accessible because there exist discriminative processes, structures and mechanisms that result in indigenous pupils being excluded from participating at educational processes. Also, the indigenous education does not count with a preferable level of acceptability because the missing contextualization of the contents and the teaching makes the indigenous pupils perceive their experiences in school as far from their realities. Moreover, indigenous education lacks adaptability because the existing alternative educational programs do not guarantee an attendance of all the needs of the different social groups of the indigenous people.

    Gestational diabetes is associated with a high risk of type 2 diabetes. However, progression rates among Indigenous women in Australia who experience high prevalence of gestational diabetes are unknown. This retrospective cohort study includes all births to women at a regional hospital in Far North Queensland, Australia, coded as having 'gestational diabetes' from 1 January 2004 to 31 December 2010 (1098 births) and receiving laboratory postpartum screening from 1 January 2004 to 31 December 2011 (n = 483 births). Women who did not receive postpartum screening were excluded from the denominator. Data were linked between hospital electronic records, routinely collected birth data and laboratories, with sample validation by reviews of medical records. Analysis was conducted using Cox-proportional regression models. Indigenous women had a greater than fourfold risk of developing type 2 diabetes within 8 years of having gestational diabetes, compared with non-Indigenous women (hazards ratio 4.55, 95% confidence interval 2.63-7.88, p Australian women have a greater than fourfold risk of developing type 2 diabetes after gestational diabetes.

    Full Text Available Recently, the demands of biofuels have increased, because of their significant role in reducing various pollutants created by fossil fuels. Here, we have collected 25 samples containing various thermotolerant microorganisms from the nine natural fermented sources of Bangladesh, such as Boiled potato (Bp, Decomposed foods (Df, Municipal liquid waste (Mlw, Municipal solid waste (Msw, Sugarcane juice (Sc, Pantavat (Pv, Sugar molasses (Sm, Tari (Tari and Watermelon juice (Wm for bioethanol production. Among them, 18 isolates are capable of producing bioethanol. Cultural, morphological, physiological, biochemical and genetic analyses were carried out under various physiological conditions. Ethanol fermentation was checked by different carbon sources, temperatures and pH. All of the isolates could grow well in the medium containing Dextrose and Arabinose and only two strains Pv-1 and Bp-2 could ferment Xylose as a sole carbon source. At 42 °C, the highest ethanol concentration 6.58% (v/v was obtained by a strain Wm-1 isolated from Watermelon juice. At 37 °C, maximal ethanol concentrations of 6.74% (v/v, 6.50% (v/v and 6.22% (v/v were obtained by the strains Bp-2, Wm-l and Pv-1, respectively. Among the various pH tested, the highest ethanol concentration 6.6% (v/v was obtained at pH 4.5 by a strain named Tari-2. Finally, yeast 26S rDNA sequencing information identified the strains Sc-2 as Saccharomyces cerevisiae Pv-2, Tari-2 and Df-1 as Pichia kudriavzevii, Mlw-l and Bp-2 as Candida tropicalis, Pv-1 as Pichia guilliermondii and Df-2 as Candida rugosa.

    The world's Indigenous peoples are experiencing an unprecedented epidemic of type 2 diabetes [T2DM] but little has been published describing the complications burden. The objective of this paper was to conduct a systematic review of T2DM complications in Indigenous populations worldwide. A literature review was conducted using PubMed and EMBASE to examine available complications data. Country, Indigenous population, authors, publication year, total sample size, Indigenous sample size, age, methodology, and prevalence of nephropathy, end-stage renal disease, retinopathy, neuropathy, lower extremity amputations, cardiovascular disease, hospitalizations and mortality due to diabetes were recorded. One-hundred and eleven studies were selected. Results revealed a disproportionate burden of disease complications among all Indigenous peoples regardless of their geographic location. Complication rates were seen to vary widely across Indigenous groups. Gaps were found in the published literature on complications among Indigenous populations, especially those living in underdeveloped countries. These gaps may be in part due to the challenges caused by varying operational practices, research methodologies, and definitions of the term Indigenous, making documentation of rates among these peoples problematic. Comprehensive surveillance applying standardized definitions and methodologies is needed to design targeted prevention and disease management strategies for Indigenous peoples with T2DM.

  7. The mental health of Indigenous peoples in Canada: A critical review of research.

    2017-03-01

    Many scholars assert that Indigenous peoples across the globe suffer a disproportionate burden of mental illness. Research indicates that colonialism and its associated processes are important determinants of Indigenous peoples' health internationally. In Canada, despite an abundance of health research documenting inequalities in morbidity and mortality rates for Indigenous peoples, relatively little research has focused on mental health. This paper provides a critical scoping review of the literature related to Indigenous mental health in Canada. We searched eleven databases and two Indigenous health-focused journals for research related to mental health, Indigenous peoples, and Canada, for the years 2006-2016. Over two hundred papers are included in the review and coded according to research theme, population group, and geography. Results demonstrate that the literature is overwhelmingly concerned with issues related to colonialism in mental health services and the prevalence and causes of mental illness among Indigenous peoples in Canada, but with several significant gaps. Mental health research related to Indigenous peoples in Canada overemphasizes suicide and problematic substance use; a more critical use of the concepts of colonialism and historical trauma is advised; and several population groups are underrepresented in research, including Métis peoples and urban or off-reserve Indigenous peoples. The findings are useful in an international context by providing a starting point for discussions, dialogue, and further study regarding mental health research for Indigenous peoples around the world.

    2012-09-01

    Full Text Available Abstract Background This project is a community-level study of equity of access to eye health services for Indigenous Australians. Methods The project used data on eye health services from multiple sources including Medicare Australia, inpatient and outpatient data and the National Indigenous Eye Health Survey. The analysis focused on the extent to which access to eye health services varied at an area level according to the proportion of the population that was Indigenous (very low = 0-1.0%, low = 1.1-3.0%, low medium = 3.1-6.0%, high medium = 6.1-10.0%, high = 10.1-20.0%, very high = 20 + %. The analysis of health service utilisation also took into account age, remoteness and the Socioeconomic Indices for Areas (SEIFA. Results The rate of eye exams provided in areas with very high Indigenous populations was two-thirds of the rate of eye exams for areas with very low indigenous populations. The cataract surgery rates in areas with high medium to very high Indigenous populations were less than half that reference areas. In over a third of communities with very high Indigenous populations the cataract surgery rate fell below the World Health Organization (WHO guidelines compared to a cataract surgery rate of 3% in areas with very low Indigenous populations. Conclusions There remain serious disparities in access to eye health service in areas with high Indigenous populations. Addressing disparities requires a co-ordinated approach to improving Indigenous people’s access to eye health services. More extensive take-up of existing Medicare provisions is an important step in this process. Along with improving access to health services, community education concerning the importance of eye health and the effectiveness of treatment might reduce reluctance to seek help.

  11. Access to primary health care services for Indigenous peoples: A framework synthesis.

    2016-09-30

    Indigenous peoples often find it difficult to access appropriate mainstream primary health care services. Securing access to primary health care services requires more than just services that are situated within easy reach. Ensuring the accessibility of health care for Indigenous peoples who are often faced with a vast array of additional barriers including experiences of discrimination and racism, can be complex. This framework synthesis aimed to identify issues that hindered Indigenous peoples from accessing primary health care and then explore how, if at all, these were addressed by Indigenous health care services. To be included in this framework synthesis papers must have presented findings focused on access to (factors relating to Indigenous peoples, their families and their communities) or accessibility of Indigenous primary health care services. Findings were imported into NVivo and a framework analysis undertaken whereby findings were coded to and then thematically analysed using Levesque and colleague's accessibility framework. Issues relating to the cultural and social determinants of health such as unemployment and low levels of education influenced whether Indigenous patients, their families and communities were able to access health care. Indigenous health care services addressed these issues in a number of ways including the provision of transport to and from appointments, a reduction in health care costs for people on low incomes and close consultation with, if not the direct involvement of, community members in identifying and then addressing health care needs. Indigenous health care services appear to be best placed to overcome both the social and cultural determinants of health which hamper Indigenous peoples from accessing health care. Findings of this synthesis also suggest that Levesque and colleague's accessibility framework should be broadened to include factors related to the health care system such as funding.

  12. Connected Activism: Indigenous Uses of Social Media for Shaping Political Change

    Directory of Open Access Journals (Sweden)

    Marisa Elena Duarte

    2017-07-01

    Full Text Available Prior studies describe digital tactics as specific strategies actors apply within broader repertoires of contention, specifically in social and political contexts. A comparison of EZLN, Idle No More, and the ongoing Rio Yaqui water rights movement reveals the kinds of community knowledge work that has to happen prior to and around activating digital tactics in Indigenous rights movements, including choices in messaging and discourses of Indigeneity, targeting of movement opponents, and selection of digital tools and techniques. Activists harness these communicative affordances to practice a politics of visibility, cultivate solidarity, diffuse an Indigenous consciousness, enforce dominant governments’ trust and treaty responsibilities, and remind many of the irrevocable injustice of colonialism. Designing methodologies that account for specific Indigenous social and political contexts as well as the affordances of various digital environments is part of the future work of Indigenous media theorists.

  13. Locating the global: culture, language and science education for indigenous students

    Science.gov (United States)

    McKinley, Elizabeth

    2005-02-01

    The international literature suggests the use of indigenous knowledge (IK) and traditional ecological knowledge (TEK) contexts in science education to provide motivation and self-esteem for indigenous students is widespread. However, the danger of alienating culture (as knowledge) from the language in which the worldview is embedded seems to have been left out of the philosophical and pedagogical debates surrounding research and comment in the field. This paper argues that one of the main ways in which indigenous knowledge systems will survive and thrive is through the establishment of programmes taught through indigenous languages so that a dialectal relationship between language and knowledge is established that continues to act as the wellspring. The article concludes by reviewing the situation in Aotearoa New Zealand with respect to the indigenous population, Maori, and the recent science education initiatives in te reo Maori (Maori language).

    2016-01-01

    Objective The Indigenous Burden of Disease (IBoD) report is the most comprehensive assessment of Indigenous disease burden in Australia. The aim of the present study was to investigate the potential effect of the IBoD report on Australian Indigenous health policy, service expenditure and research funding. Findings have significance for understanding factors that may influence Indigenous health policy. Methods The potential effect of the IBoD report was considered by: (1) conducting a text search of pertinent documents published by the federal government, Council of Australian Governments and the National Health and Medical Research Council of Australia (NHMRC) and observing the quantity and quality of references to IBoD; (2) examining data on government Indigenous healthcare expenditure for trends consistent with the findings and policy implications of the IBoD report; and (3) examining NHMRC Indigenous grant allocation trends consistent with the findings and policy implications of the IBoD report. Results Of 110 government and NHMRC documents found, IBoD was cited in 27. Immediately after publication of the IBoD report, federal and state governments increased Indigenous health spending (relative to non-Indigenous), notably for community health and public health at the state level. Expenditure on Indigenous hospital separations for chronic diseases also increased. These changes are broadly consistent with the findings of the IBoD report on the significance of chronic disease and the need to address certain risk factors. However, there is no evidence that such changes had a causal connection with the IBoD study. After publication of the IBoD report, changes in NHMRC Indigenous research funding showed little consistency with the findings of the IBoD report. Conclusions The present study found only indirect and inconsistent correlational evidence of the potential influence of the IBoD report on Indigenous health expenditure and research funding. Further assessment of

    2000-01-01

    This research program is directed at improving the knowledge of reservoir ecology and developing practical microbial solutions for improving oil production. The goal is to identify indigenous microbial populations which can produce beneficial metabolic products and develop a methodology to stimulate those select microbes with inorganic nutrient amendments to increase oil recovery.This microbial technology has the capability of producing multiple oil releasing agents. The potential of the system will be illustrated and demonstrated by the example of biopolymer production on oil recovery. Research has begun on the program and experimental laboratory work is underway. Polymer-producing cultures have been isolated from produced water samples and initially characterized. Concurrently, a microcosm scale sand-packed column has been designed and developed for testing cultures of interest, including polymer-producing strains. In research that is planned to begin in future work, comparative laboratory studies demonstrating in situ production of microbial products as oil recovery agents will be conducted in sand pack and cores with synthetic and natural field waters at concentrations, flooding rates, and with cultures and conditions representative of oil reservoirs.

    Full Text Available Indigenous Australians continue to experience significantly poorer outcomes from cancer than non-Indigenous Australians. Despite the importance of culturally appropriate cancer services in improving outcomes, there is a lack of awareness of current programs and initiatives that are aimed at meeting the needs of Indigenous patients. Telephone interviews were used to identify and describe the Indigenous-specific programs and initiatives that are implemented in a subset of the services that participated in a larger national online survey of cancer treatment services. Fourteen services located across Australia participated in the interviews. Participants identified a number of factors that were seen as critical to delivering culturally appropriate treatment and support, including having a trained workforce with effective cross-cultural communication skills, providing best practice care, and improving the knowledge, attitudes, and understanding of cancer by Indigenous people. However, over a third of participants were not sure how their service compared with others, indicating that they were not aware of how other services are doing in this field. There are currently many Indigenous-specific programs and initiatives that are aimed at providing culturally appropriate treatment and supporting Indigenous people affected by cancer across Australia. However, details of these initiatives are not widely known and barriers to information sharing exist. Further research in this area is needed to evaluate programs and initiatives and showcase the effective approaches to Indigenous cancer care.

  1. Moving Toward Spatial Solutions in Marine Conservation with Indigenous Communities

    2008-06-01

    Full Text Available Community and resource user support has often been declared as essential to achieving globally agreed targets for marine protection. Given that indigenous people in Canada have resource use rights, we engaged two indigenous communities in British Columbia for their views on marine planning and protected areas. We developed a three-phased approach for executing our research: building research partnerships, carrying out individual interviews, and holding community discussion sessions. Participants expressed a common goal of recovering depleted species and ensuring the sustainability of indigenous fishing. We found strong support for spatial protection measures, and significant overlaps amongst participants in the areas suggested for protection. The most common type of protection recommended by participants was the exclusion of commercial and recreational fisheries while allowing for indigenous fishing; this stands in contrast to the emphasis on strict no-take MPAs advocated in the literature. Similarities in the goal, and level and areas of protection point to a gap in conservation approaches: the conservation of important areas and resources to indigenous people, allowing the continued practice and adaptation of their culture.

  2. Indigenous Participation in Intercultural Education: Learning from Mexico and Tanzania

    2012-12-01

    Full Text Available Intercultural education seeks to create a forum for integrating Western scientific knowledge and indigenous knowledge to address local and global challenges such as biocultural diversity conservation, natural resource management, and social justice for indigenous peoples. Intercultural education is based on learning together with, rather than learning about or from, indigenous communities. In the best examples, problem-based learning dissolves the dichotomy between indigenous and nonindigenous, resulting in full partnerships in which participants share expertise to meet mutual needs. With reference to literature and two illustrative examples of intercultural education initiatives in Mexico and Tanzania, we present an original conceptual framework for assessing indigenous participation in intercultural education. This incorporates a new ladder of participation depth (in relation to both curriculum content and decision making alongside separate considerations of breadth, i.e., stakeholder diversity, and scope, i.e., the number of key project stages in which certain stakeholder groups are participating. The framework can be used to compare intercultural education initiatives in differing contexts and might be adaptable to other intercultural work.

    2007-05-21

    In August 2006, the Aboriginal Land Rights (Northern Territory) Amendment Bill 2006 (Cwlth) was passed into law, introducing, among other things, a system of 99-year leases over Indigenous townships. The leasing scheme will diminish the control that traditional owners previously exercised over their lands. This is at odds with research indicating that control over land is a positive influence on Indigenous health.

  5. Priority Setting in Indigenous Health: Why We Need an Explicit Decision Making Approach

    Directory of Open Access Journals (Sweden)

    Michael E. Otim

    2015-06-01

    Full Text Available Indigenous Australians have significantly poorer health outcomes than the non-Indigenous population worldwide. The Australian government has increased its investment in Indigenous health through the "Closing the Health Gap" initiative. Deciding where to invest scarce resources so as to maximize health outcomes for Indigenous peoples may require improved priority setting processes. Current government practice involves a mix of implicit and explicit processes to varying degrees at the macro and meso decision making levels. In this article, we argue that explicit priority setting should be emphasized in Indigenous health, as it can ensure that the decision making process is accountable, systematic, and transparent. Following a review of the literature, we outline four key issues that need to be considered for explicit priority setting: developing an Indigenous health "constitution," strengthening the evidence base, selecting mechanisms for priority setting, and establishing appropriate incentives and institutional structure. We then summarize our findings into a checklist that can help a decision makers ensure that explicit priority setting is undertaken in Indigenous health. By addressing these key issues, the benefits of an explicit approach, which include increased efficiency, equity, and use of evidence, can be realized, thereby maximizing Indigenous health outcomes.

    2014-01-01

    This article describes a pilot study evaluating the sensitivity of Indigenous community health to climate change impacts on Salish Sea shorelines (Washington State, United States and British Columbia, Canada). Current climate change assessments omit key community health concerns, which are vital to successful adaptation plans, particularly for Indigenous communities. Descriptive scaling techniques, employed in facilitated workshops with two Indigenous communities, tested the efficacy of ranking six key indicators of community health in relation to projected impacts to shellfish habitat and shoreline archaeological sites stemming from changes in the biophysical environment. Findings demonstrate that: when shellfish habitat and archaeological resources are impacted, so is Indigenous community health; not all community health indicators are equally impacted; and, the community health indicators of highest concern are not necessarily the same indicators most likely to be impacted. Based on the findings and feedback from community participants, exploratory trials were successful; Indigenous-specific health indicators may be useful to Indigenous communities who are assessing climate change sensitivities and creating adaptation plans.

    2017-01-01

    Much biodiversity lives on lands to which Indigenous people retain strong legal and management rights. However this is rarely quantified. Here we provide the first quantitative overview of the importance of Indigenous land for a critical and vulnerable part of biodiversity, threatened species, using the continent of Australia as a case study. We find that three quarters of Australia's 272 terrestrial or freshwater vertebrate species listed as threatened under national legislation have projected ranges that overlap Indigenous lands. On average this overlap represents 45% of the range of each threatened species while Indigenous land is 52% of the country. Hotspots where multiple threatened species ranges overlap occur predominantly in coastal Northern Australia. Our analysis quantifies the vast potential of Indigenous land in Australia for contributing to national level conservation goals, and identifies the main land management arrangements available to Indigenous people which may enable them to deliver those goals should they choose to do so.

    Full Text Available Employing a reflexive and co-constructed narrative analysis, this article explores our experiences as a non-Indigenous doctoral student and a First Nations research assistant working together within the context of a community-based participatory Indigenous geography research project. Our findings revealed that within the research process there were experiences of conflict, and opportunities to reflect upon our identity and create meaningful relationships. While these experiences contributed to an improved research process, at a broader level, we suggest that they also represented our personal stories of reconciliation. In this article, we share these stories, specifically as they relate to reconciliatory processes of re-education and cultural regeneration. We conclude by proposing several policy recommendations to support research as a pathway to reconciliation in Canada.

    Full Text Available The IDRC-funded project 'Empowering Indigenous Peoples and Knowledge Systems Related to Climate Change and Intellectual Property Rights' is part of the Open and Collaborative Science in Development Network (OCSDNet. The project “examiners processes of open and collaborative science related to indigenous peoples’ knowledge, climate change and intellectual property rights”. Natural Justice, the lead organisation has a strong ethical stance on the agency and control over knowledge being vested with the contributing project participants, communities of the Nama and Griqua peoples of the Western Cape of South Africa. The project focuses on questions of how climate change is affecting these communities, how do they produce and maintain knowledge relating to climate change, how that knowledge is characterised and shared (or not with wider publics, and how legal frameworks promote or hinder the agenda of these indigenous communities and their choices to communicate and collaborate with wider publics. Indigenous Knowledge is an area where ethical issues of informed consent, historical injustice, non-compatible epistemologies and political, legal, and economic issues all collide in ways that challenge western and Anglo-American assumptions about data sharing. The group seeks to strongly model and internally critique their own ethical stance in the process of their research, through for instance, using community contracts and questioning institutional informed consent systems.

    2017-01-01

    Alberta's Indigenous population is growing, yet health care access may be limited. This paper presents a comprehensive review on health care access among Indigenous populations in Alberta with a focus on the health care services use and barriers to health care access. Scientific databases (PubMed, EMBASE, CINAHL, and PsycINFO) and online search engines were systematically searched for studies and grey literature published in English between 2000 and 2013 examining health care services access, use and barriers to access among Indigenous populations in Alberta. Information on health care services use and barriers to use or access was synthesized based on the MOOSE guidelines. Overall, compared to non-Indigenous populations, health care use rates for hospital/emergency room services were higher and health care services use of outpatient specialists was lower among Indigenous peoples. Inadequate numbers of Indigenous health care professionals; a lack of cross-cultural training; fear of foreign environments; and distance from family and friends were barriers to health care use and access. Inequity in social determinants of health among Indigenous peoples and inadequate "health services with prevention approaches," may contribute to present health disparities between Indigenous and non-Indigenous populations in the province.

    Full Text Available Abstract Background Studies that compare Indigenous Australian and non-Indigenous patients who experience a cardiac event or chest pain are inconclusive about the reasons for the differences in-hospital and survival rates. The advances in diagnostic accuracy, medication and specialised workforce has contributed to a lower case fatality and lengthen survival rates however this is not evident in the Indigenous Australian population. A possible driver contributing to this disparity may be the impact of patient-clinician interface during key interactions during the health care process. Methods/Design This study will apply an Indigenous framework to describe the interaction between Indigenous patients and clinicians during the continuum of cardiac health care, i.e. from acute admission, secondary and rehabilitative care. Adopting an Indigenous framework is more aligned with Indigenous realities, knowledge, intellects, histories and experiences. A triple layered designed focus group will be employed to discuss patient-clinician engagement. Focus groups will be arranged by geographic clusters i.e. metropolitan and a regional centre. Patient informants will be identified by Indigenous status (i.e. Indigenous and non-Indigenous and the focus groups will be convened separately. The health care provider focus groups will be convened on an organisational basis i.e. state health providers and Aboriginal Community Controlled Health Services. Yarning will be used as a research method to facilitate discussion. Yarning is in congruence with the oral traditions that are still a reality in day-to-day Indigenous lives. Discussion This study is nestled in a larger research program that explores the drivers to the disparity of care and health outcomes for Indigenous and non-Indigenous Australians who experience an acute cardiac admission. A focus on health status, risk factors and clinical interventions may camouflage critical issues within a patient

    The sugarcane bagasse hydrolysate, which is rich in xylose, can be used as culture medium for Candida guilliermondii in xylitol production. However, the hydrolysate obtained from bagasse by acid hydrolysis at 120 degrees C for 20 min has by-products (acetic acid and furfural, among others), which are toxic to the yeast over certain concentrations. So, the hydrolysate must be pretreated before using in fermentation. The pretreatment variables considered were: adsorption time (15,37.5, and 60 min), type of acid used (H2So4 and H3Po4), hydrolysate concentration (original, twofold, and fourfold concentrated), and active charcoal (0.5, 1.75 and 3.0%). The suitability of the pretreatment was followed by measuring the xylose reductase (XR) and xylitol dehydrogenase (XD) activity of yeast grown in each treated hydrolysate. The response surface methodology (2(4) full factorial design with a centered face) indicated that the hydrolysate might be concentrated fourfold and the pH adjusted to 7.0 with CaO, followed by reduction to 5.5 with H3PO4. After that it was treated with active charcoal (3.0%) by 60 min. This pretreated hydrolysate attained the high XR/XD ratio of 4.5.
