    This work reports the first molecular analysis study of chicken anaemia virus (CAV) in backyard chickens in Africa using molecular cloning and sequence analysis to characterize CAV strains obtained from commercial chickens and Nigerian backyard chickens. Partial VP1 gene sequences were determined for three CAVs from commercial chickens and for six CAV variants present in samples from a backyard chicken. Multiple alignment analysis revealed that the 6% and 4% nucleotide diversity obtained respectively for the commercial and backyard chicken strains translated to only 2% amino acid diversity for each breed. Overall, the amino acid composition of Nigerian CAVs was found to be highly conserved. Since the partial VP1 gene sequence of two backyard chicken cloned CAV strains (NGR/CI-8 and NGR/CI-9) were almost identical and evolutionarily closely related to the commercial chicken strains NGR-1, and NGR-4 and NGR-5, respectively, we concluded that CAV infections had crossed the farm boundary.

    Backyard poultry are regaining popularity in Europe and increased interest in the health and management of non-commercial farms has resulted. Furthermore, commercial poultry farm owners have become concerned about the risk represented by contagious avian diseases that nearby backyard poultry could transmit. Fifty-one voluntary backyard chicken farms were visited between October 2012 and January 2013. Blood samples and individual cloacal swabs were collected from 457 chickens. In 44 farms (86%), one or more of the tested chickens had antibodies against avian encephalomyelitis and chicken infectious anaemia viruses, 24 farms (47%) had chickens seropositive for infectious bronchitis virus, 10 farms (20%) had chickens seropositive for infectious bursal disease virus, six farms (12%) had chickens seropositive for infectious laryngotracheitis virus and two farms (5.4%) had chickens seropositive for avian influenza virus. No farms had chickens seropositive for Newcastle disease virus. Of the 51 farms, five (10%) had chickens positive for coronavirus reverse transcription polymerase chain reaction. A phylogenetic analysis showed that all backyard chicken coronaviruses collected were QX type infectious bronchitis viruses. All chickens tested for avian influenza and Newcastle disease viruses using real time reverse transcription polymerase chain reaction were negative. To our knowledge, there is no evidence to date to suggest that these diseases would have been transmitted between commercial and non-commercial flocks.

    Poultry is commonly raised by households in rural Bangladesh. In 2007, the Government of Bangladesh began a mass media campaign to disseminate 10 recommended precautions to prevent transmission of H5N1 from poultry to humans. This longitudinal study explored the contribution of backyard poultry on household economy and nutrition and compared poultry-raising practices to government recommendations. From 2009 to 2012, we enrolled a nationally representative sample of 2489 primary backyard poultry raisers from 115 rural villages selected by probability proportional to population size. Researchers interviewed the raisers to collect data on poultry-raising practices. They followed the raisers for 2-12 months to collect data on household income and nutrition from poultry. Income from backyard poultry flocks accounted for 2.8% of monthly household income. Return on annual investment (ROI) per flock was 480%. Yearly, median family consumption of eggs was one-fifth of the total produced eggs and three poultry from their own flock. Respondents' reported practices conflicted with government recommendations. Sixty per cent of raisers had never heard of avian influenza or 'bird flu'. Among the respondents, 85% handled sick poultry or poultry that died due to illness, and 49% slaughtered or defeathered sick poultry. In 37% of households, children touched poultry. Fifty-eight per cent never washed their hands with soap after handling poultry, while Bangladesh provides important income and nutrition with an excellent ROI. Government recommendations to reduce the risk of avian influenza transmission did not impact the behaviour of poultry producers. Further research should prioritize developing interventions that simultaneously reduce the risk of avian influenza transmission and increase productivity of backyard poultry. © 2016 Blackwell Verlag GmbH.

    1. The aim of the study was to collect baseline data on welfare, biosecurity and diseases of backyard chickens kept in the Greater London Urban Area (GLUA), United Kingdom (UK). 2. A total of 65 backyard chicken flock-keepers were recruited from May to July 2010 through adverts on websites, at City farms, veterinary practices and pet feed stores and surveyed by means of a questionnaire. A total of 30 responses were suitable for analysis. 3. Information on keepers' and flocks' characteristics, housing and husbandry practices and owners' knowledge of health problems in chickens and zoonotic diseases was collected. A welfare assessment protocol was developed and the flocks assessed accordingly. 4. Results showed that chickens were generally provided with living conditions that allowed them to perform their natural behaviours. 5. Most of the flock owners did not comply with the regulations of the Department for Environment, Food and Rural Affairs (Defra) on the feeding of catering waste. 6. Disease prevention measures such as vaccination and biosecurity, including limiting the access of human visitors, wild birds and rodents to the flocks were rare. 7. A lack of avian and zoonotic disease knowledge and awareness among the owners has implications for disease control and highlights the need for improved communication between owners, authorities and veterinarians.

    Full Text Available Amber Roegner,1 Federico Giannitti,2 Leslie W Woods,2 Asli Mete,2 Birgit Puschner1,2 1Department of Molecular Biosciences, School of Veterinary Medicine, University of California, Davis, CA, USA; 2California Animal Health and Food Safety Laboratory System, School of Veterinary Medicine, University of California, Davis, CA, USA Abstract: Lead intoxication in livestock has historically been associated with cattle turned out to pasture and accidental ingestion of lead from drinking crankcase oil, licking grease from machinery, chewing on plumbing or batteries, or drinking water contaminated from leaching materials. Even with the decrease in manufactured items produced with lead, contaminants persist in the landscape and may enter the food supply through animal products. Changing patterns of open range herds moving to new pasture and the increased popularity of urban/suburban backyard chickens or other livestock necessitates public awareness about the clinical signs of lead intoxication, the potential for subclinical animals, public health concerns, particularly for exposure in children, and testing options available. Cases of lead intoxication in livestock demand a thorough case work-up to identify all sources of lead, address subclinical cases, evaluate risk to consumers, and make management suggestions for future prevention. We discuss four recent cases of confirmed lead poisoning in backyard chickens and open range cattle and assess the public health implications therein. Taken as a whole and considering the potential of the remaining herd or flock to be affected without necessarily showing signs, public health officials and veterinarians should be prepared to advise clients on case work-up and management and prevention considerations. Backyard chickens and cattle may not present for suspected lead poisoning as in several of the cases discussed herein yet may still contain concerning tissue or blood levels.

    To characterize Pasteurella isolated from backyard chickens using whole cell protein lysate profiles and random amplified polymorphic DNA (RAPD) techniques to show their genetic relationship because Pasteurella multocida (P. multocida) is an important cause of fatal infections in backyard chickens. Twenty one P. multocida isolates were recovered previously from clinical cases of fowl cholera belonging to individual owners and phenotypically analyzed using biochemical tests and serotyping were used for the genetic characterization. Phylogenetic study based on both methods revealed that the recovered population of P. multocida isolated from backyard chickens differs markedly, constituting a well-separated cluster and appearance of 3 distinguishing lineages with greater discrimination shown by RAPD-PCR that resulted in two suclusters in cluster A and three subclusters in cluster B and were related greatly with capsular serogroups for the examined strains. The whole cell protein revealed the presence of dominant protein bands at approximately 41 and 61 kDa in all of the examined isolates that may be a virulent proteins share in the increasing of its pathogenicity. Clear distinctive bands ranged from 123 to 1554 bp. Based on the previous findings, there are three spreading clusters that may indicate the association of a small number of P. multocida variants with the majority of cases suggesting that certain clones of P. multocida are able to colonize the examined backyard chickens. Also, the ease and rapidity of RAPD-PCR support the use of this technique as alternative to the more labour-intensive SDS-PAGE system for strain differentiation and epidemiological studies of avian P. multocida. Further application of RAPD technology to the examination of avian cholera outbreaks in commercially available flocks may facilitate more effective management of this disease by providing the potential to investigate correlations of P. multocida genotypes, to identify affiliations

    Soil in urban areas contains the residues of past land-uses and practices. Urban farming (keeping chickens, vegetable gardening) requires soil disturbance and can increase exposure of residents to these contaminants. We measured the level of lead, arsenic, cadmium, copper and zinc contaminants in soil and eggs from 26 backyard chicken coops across the Lower Hunter, NSW Australia. We compared the levels of metals in soil to Health Investigation Levels and metals in home-grown eggs to the levels in commercial eggs tested in this study or published by Food Standards Australia New Zealand. The levels of arsenic, cadmium, copper and zinc were low, both in soil and in home-grown eggs and were comparable to commercial eggs tested in this study. The Health Investigation Level for lead in soil (300 mg lead/kg soil) was exceeded at 7 of the 26 sites. The level of lead in home-grown eggs was generally higher than in commercial eggs. The reference health standard for meat (including chicken), fruit and vegetables of 0.1 mg lead/kg produce was exceeded in home-grown eggs from 7 of the 26 sites. There was a significant relationship between the lead level in eggs and the lead level in soil accessible to chickens. As soil lead increased, concentrations of lead in eggs tended to increase. No relationship was detected between the lead level in feed and in eggs. We recommend strategies to reduce ingestion of soil by chickens thereby reducing metal contamination in home-grown eggs. - Highlights: • We measured metal contaminants in soil and eggs from 26 backyard chicken coops in NSW Australia. • The levels of As, Cd, Cu and Zn were low, both in soil and in home-grown eggs • The HIL for Pb in soil and the health standard for Pb in produce was exceeded in 7 of the 26 sites. • The level of Pb in home-grown eggs was higher than in commercial eggs. • As soil Pb increased, concentrations of Pb in eggs increased. No relationship was detected for Pb in feed.

    Full Text Available An exploratory serosurvey was conducted to determine the presence of circulating antibodies to avian pathogens in backyard chickens from Los Achiotes (LAC, a satellite community of Jalapa City, located in eastern Guatemala. Blood samples from 51 adult chickens belonging to 51 households were taken and investigated for the presence of antibodies to Avian Influenza (AI, Newcastle Disease (ND, Infectious Bronchitis (IB, Infectious Bursal Disease (IBD, Mycoplasma gallisepticum (MG and M. synoviae (MS. Antibodies for AI, ND, were investigated by Hemagglutination Inhibition, for IB and IBD by ELISA (BioChek® and for MG and MS by a rapid serum plate agglutination test. The cut-off point for positive titers was 1:4 for AI and ND and a 0.2 S/P ratio for IB and IBD. All sampled chickens were positive for concomitant antibodies to various pathogens. Over half of the chickens were positive reactors to antibodies to all six tested pathogens; about a third carried antibodies to five and the rest to four or three. The frequencies of positive reactors were: AI = 27 (53%; ND = 49 (96.1%; IB = 50 (98%; IBD = 51 (100%; MG = 45 (88% and MS = 48 (94%. The results show that the dynamic population of backyard chickens in LAC could be a potential threat to backyard poultry, farm poultry, wild birds and human population. The need to develop interventions and policies following the One Health approach (animal health to achieve human health is stressed.

    Fatty liver hemorrhagic syndrome, characterized by sudden death in overconditioned hens due to hepatic rupture and hemorrhage, is one of the leading noninfectious idiopathic causes of mortality in backyard chickens. Nutritional, genetic, environmental, and hormonal factors, or combinations of these, have been proposed yet not proven as the underlying cause. In an attempt to characterize the hepatic changes leading to the syndrome, this retrospective case study examined 76 backyard chickens that were diagnosed with fatty liver hemorrhagic syndrome between January 2007 and September 2012 and presented for necropsy to the diagnostic laboratory of the California Animal Health and Food Safety Laboratory System. A majority of the birds were female (99%), obese (97.5%), and in active lay (69.7%). Livers were examined histologically, and the degree of hepatocellular vacuolation (lipidosis), the reticular stromal architecture, the presence of collagenous connective tissue, and vascular wall changes were evaluated and graded using hematoxylin and eosin, Gomori's reticulin, oil red O, Masson's trichrome, and Verhoeff-Van Gieson stains. Interestingly, there was no correlation between lipidosis and reticulin grades; hepatocellular lipidosis was absent in 22% of the cases and mild in 26% of the cases. Additionally, there was evidence of repeated bouts of intraparenchymal hemorrhage before the acute "bleed-out" in 35.5% of the cases. These data are not supportive of the previously proposed causes and provide a framework for future studies to elucidate the pathogenesis of this condition. Furthermore, the data shown in this study support hemorrhagic liver syndrome as a more accurate name, as hepatic lipidosis is absent in a significant proportion of ruptured livers. © The Author(s) 2013.

    This paper presents the findings of an exploratory study on ethnoveterinary medicines used for backyard pigs and backyard chickens in Trinidad and Tobago. Research data was collected from 1995 to September 2000. Six plants are used for backyard pigs. Crushed leaves of immortelle (Erythrina pallida, E. micropteryx) are used to remove dead piglets from the uterus. Leaf decoctions of bois canôt (Cecropia peltata) and bamboo (Bambusa vulgaris) are used for labour pains or leaves are fed as a postpartum cleanser. Boiled green papaya fruit (Carica papaya) is fed to pigs to induce milk let-down. The leaves and flowers of male papaya plants (Carica papaya) are fed to deworm pigs. Sour orange juice (Citrus aurantium) is given to pigs to produce lean meat, and coffee grounds are used for scours. Eyebright and plantain leaves (Plantago major) are used for eye injuries of backyard chickens. Worm grass (Chenopodium ambrosioides) and cotton bush (Gossypium species) are used as anthelmintics. Aloe gel (Aloe vera) is used for internal injuries and the yellow sap from the cut Aloe vera leaf or the juice of Citrus limonia is used to purge the birds. A literature review revealed few toxicity concerns and the potential usefulness of the plants.

    Concurrent fowlpox and candidiasis diseases occurred in a backyard chicken flock. Four deceased chickens (one Nagoya breed and three white silkie chickens) were examined for diagnosis. At necropsy, white curd-like plaques were observed in the crop. Fungal elements that stained positive for Candida albicans with immunohistochemistry were distributed throughout the tongue, choanal mucosa, esophagus, and crop. Typical fowlpox lesions, composed of proliferating epithelial cells with ballooning degeneration and viral intracytoplasmic inclusions, were observed in the conjunctiva, nasal mucosa, and skin around the cloaca. Interestingly, hyperplastic interfollicular epithelium with rare virus inclusions was observed in the bursa of Fabricius (BF). Some bursal follicles were replaced by proliferating epithelial cells. These proliferating cells immunohistochemically stained positive for cytokeratin. PCR and subsequent genetic sequencing detected the C. albicans gene in the crop, and fowlpox virus genes in the BF. These results indicate that this outbreak was a rare presentation of fowlpox in spontaneously infected chickens, with unusual pox lesions in the BF.

    Full Text Available Abstract The aim of the present study was to investigate the occurrence of anti-Toxoplasma gondii antibodies and parasite DNA in backyard chickens bred in the metropolitan area of Recife, Brazil. In total, 212 serum samples were collected from 16 properties, and 12 backyard chickens were collected in the six sanitary districts of Recife. An indirect immunofluorescence assay (IFA was used to investigate the occurrence of anti-Toxoplasma gondii antibodies. Polymerase chain reaction (PCR was used to detect T. gondii DNA in brain, heart, liver and lung specimens. Of the samples analyzed by serology, 86/212 (40.56% were positive; of the samples analyzed by PCR, 2/12 (16.7% were positive, with both samples positive by both tests (serological and molecular. The presence of antibody anti-T. gondii and parasite DNA in tissues of these animals are worrying aspects for public health because there is a risk of transmission of the parasite to humans through eating undercooked or raw meat. Based on the results, the adoption of preventive measures to prevent the cats access to the chickens creations should be encouraged, since these animals were identified in most of the studied properties.

    In Bangladesh, highly pathogenic avian influenza H5N1 is endemic in poultry. This study aimed to understand the biosecurity conditions and farmers' perception of avian influenza biosecurity in Bangladeshi small commercial chicken farms. During 2011-2012, we conducted observations, in-depth interviews and group discussions with poultry farmers in 16 farms and in-depth interviews with seven local feed vendors from two districts. None of the farms were completely segregated from people, backyard poultry, other animals, households, other poultry farms or large trees. Wild birds and rodents accessed the farms for poultry feed. Farmers usually did not allow the buyers to bring egg trays inside their sheds. Spraying disinfectant in the shed and removing feces were the only regular cleaning and disinfection activities observed. All farmers sold or used untreated feces as fish feed or fertilizer. Farmers were more concerned about Newcastle disease and infectious bursal disease than about avian influenza. Farmers' understanding about biosecurity and avian influenza was influenced by local vendors. While we seldom observed flock segregation, some farmers used measures that involved additional cost or effort to protect their flocks. These farmers could be motivated by interventions to protect their investment from diseases they consider harmful. Future interventions could explore the feasibility and effectiveness of low-cost alternative biosecurity measures.

    This study was carried out on free-range backyard chickens, domestic pigeons (Columba livia domestica) and turkeys from May 2012 to April 2013 to determine the prevalence and identify the species of ectoparasites in Kermanshah province, west of Iran. Of the total of 600 free-range backyard chickens (185 ♂ and 415 ♀), 700 domestic pigeons (278 ♂ and 422 ♀) and 150 turkeys (53 ♂ and 97 ♀), 389 (64.83 %), 608 (86.85 %) and 54 (36 %) were infected with one or more parasites respectively. Eleven ectoparasites species including five of lice (50.16 % Menacanthus stramineus, 13.66 % Menopon gallinae, 4.83 % Cuclotogaster heterographus, 5.16 % Goniocotes gallinae, 2.33 % Goniodes gigas), three of mites (26.33 % Dermanyssus gallinae, 8.5 % Ornithonyssus bursa, 7 % Cnemidocoptes mutans), one of tick (78.66 % Argas persicus) and two of flea (12.33 % Echidnophaga gallinacea, 2 % Pulex irritans) were found in the backyard chickens. The domestic pigeons were infected with six species of parasites including: Columbicola columbae (61.7 %), M. gallinae (10.43 %), M. stramineus (9 %), D. gallinae (8.28 %), Argas reflexus (74.14 %) and Pseudolynchia canariensis (27.7 %). The ectoparasites species recorded in turkeys were M. gallinae (14 %), M. stramineus (8 %), D. gallinae (12.66 %), C. mutans (6 %), A. persicus (24.66 %) and E. gallinacean (6 %). This is the first survey to determine the prevalence and identify the species of ectoparasites among free-range backyard chicken, domestic pigeons and turkeys in Kermanshah province. The high prevalence rate of ectoparasites in free-range backyard chickens and domestic pigeons indicates that parasitic infection is a common problem in this area.

    Full Text Available Fowl poxvirus (FPV infection was observed in unvaccinated backyard chickens. A total of 15 birds were affected in a flock of 37. Pock lesions were observed on the comb, eyelids, beak and wattles. The birds appeared sick with roughened feathers and stunted growth. No mortality was recorded. DNA was isolated from scabs and polymerase chain reaction (PCR was performed to amplify the 4b core protein gene of FPV, the envelope (env gene of reticuloendotheliosis virus (REV and the region of FPV flanking REV 5´ long terminal repeat (LTR. Correct-size PCR products of 578 bp, 807 bp and 370 bp, respectively, were observed in agarose gel electrophoresis. Sequence analysis of these products suggests that the virus was an FPV with a genome containing an integrated near full-length REV provirus. Given the fact that REV has been associated with immunosuppression, its presence in the genome of FPV appears to play an important role in the pathogenesis of fowl pox and presumably prolongs persistence of FPV in bird populations. In the present case, fowl pox has been observed to have persisted for about three years in fowl that were reared in backyard systems in villages.

    The commercial flocks in Yucatan, Mexico are free of Newcastle disease virus (NDV) in its velogenic viscerotropic form, but little is known about the disease status of backyard poultry. A seroprevalence survey in 30 villages using haemagglutination inhibition (HI) tests for infectious bronchitis virus (IBV) and NDV antibodies was carried out from December 1997 to June 1998. The seroprevalences were 56.5% (95% CI 50-63%) for IBV and 2.2% (95% CI 0.5-3.8%) for NDV. All the villages had chickens that were positive for antibodies to IBV and nine of the villages had chickens that were positive for antibodies to NDV. This suggests that IBV may be responsible for a large proportion of the respiratory disease observed in backyard chickens in Yucatan. The implications of these findings are discussed, including the highly susceptible status of the backyard chickens in Yucatan to NDV and the possibility of this virus being one cause of the syndrome known as mortandad by the local people.

    Full Text Available The prevalence of Pasteurella multocida strains among 275 backyard chickens from different regions of Upper Egypt was studied. A total of 21 isolates of P. multocida were recovered in 21 out of 275 chickens tested (7.6% and were confirmed using phenotypic characterisation. Somatic serotyping of the 21 isolates resulted in 12 isolates being classed as serotype A:1 (57.14%, 4 as serotype A:3 (19.05% and 5 could not be typed (23.8%. Capsular typing, using multiplex polymerase chain reaction (PCR, demonstrated that 18 strains were capsular type A (85.7%, and 3 were type D (14.3%. The present findings suggest that a multiplex capsular PCR could be valuable for the rapid identification of P. multocida in cases of fowl cholera infection. A total of 5 isolates of P. multocida were selected to study their pathogenicity in embryonated chicken eggs instead of conducting a study in mature chickens. The results showed a variation in pathogenicity between the strains tested, namely: serotype A:1 strains caused 80% mortality, in contrast to 20% mortality by type D strains. Pathological findings included severe congestion of the entire embryo, haemorrhaging of the skin, feather follicles and toe, and ecchymotic haemorrhages on the liver of the inoculated embryos. The observations in this study indicate that P. multocida serogroup A could be highly pathogenic for mature chickens and therefore might be a cause of considerable economic losses in commercial production. A total of 10 isolates were subjected to antimicrobial susceptibility to determine the minimal inhibitory concentration of 7 antimicrobials. All isolates were susceptible to ciprofloxacin, florfenicol, streptomycin and sulphamethoxazol with trimethoprim and with varying degrees of sensitivity to the other agents.

    Full Text Available Seventy-eight chickens from a very high poultry density (approximately eight million region and twelve backyard chickens from neighboring areas were analyzed by histopathology and additional techniques for the presence of the infectious laryngotracheitis virus. The virus distribution was determined in different tissues using immunohistochemistry (IHC and polymerase chain reaction (PCR. The disease was histopathologically diagnosed in 41.0% (32/78 of the commercial layers. Lesions were mainly characterized by syncytial cells with eosinophilic intranuclear inclusion body formed from the hyperplastic epithelium of the upper respiratory tract, primary and secondary bronchi, and conjunctiva. IHC showed 70% (21/30 positive signal in the larynx/trachea and, 53.8% (14/26 in the lungs, either in epithelial cells or syncytia. In the turbinates and paranasal sinuses, 29.6% (8/27 of samples showed positive signal. PCR detected the following gallid herpesvirus 1-positive percentages: conjunctiva 63.2% (31/49, lungs 57.6% (30/52, turbinates and paranasal sinuses 56% (28/50, and larynx/trachea 50% (39/78. IHC showed to be a useful additional tool for definitive ILT diagnosis, especially during the subacute phase of the disease when syncytial cells with intranuclear inclusion bodies are no longer observed. PCR using specific primers from ICP4 gene, generating a product of 237 base pairs, was sensitive for ILT diagnosis, and very useful for rapid detection of GaHV-1 in chickens. Fixed tissues allowing histopatological examination and detection of GaHV-1 by PCR, are a good option in areas where farms are located several hundred kilometers away from a diagnostic center, reducing problems with conservation of fresh samples and the risk of virus spread.

    Thermophilic Campylobacter species are a major cause of bacterial foodborne diarrhoea in humans worldwide. Poultry and their products are the predominant source for human campylobacteriosis. Resistance of Campylobacter to antibiotics is increasing worldwide, but little is known about the antibiotic resistance in Campylobacter isolated from chicken in Kenya. In this study, 35 suspected Campylobacter strains isolated from faeces and cloacal swabs of chicken were tested for their susceptibility to seven antibiotics using a broth microdilution assay and molecular biological investigations. Overall, DNA of thermophilic Campylobacter was identified in 53 samples by PCR (34 C. jejuni, 18 C. coli and one mix of both species) but only 35 Campylobacter isolates (31 C. jejuni and 4 C. coli) could be re-cultivated after transportation to Germany. Isolates were tested for their susceptibility to antibiotics using a broth microdilution assay. Additionally, molecular biological detection of antibiotic resistance genes was carried out. C. jejuni isolates showed a high rate of resistance to nalidixic acid, tetracycline and ciprofloxacin of 77.4, 71.0 and 71.0 %, respectively. Low resistance (25.8 %) was detected for gentamicin and chloramphenicol. Multidrug resistance in C. jejuni could be detected in 19 (61.3 %) isolates. Resistance pattern of C. coli isolates was comparable. Resistance to ciprofloxacin was confirmed by MAMA-PCR and PCR-RFLP in all phenotypically resistant isolates. The tet(O) gene was detected only in 54.5 % of tetracycline resistant C. jejuni isolates. The tet(A) gene, which is also responsible for tetracycline resistance, was found in 90.3 % of C. jejuni and in all C. coli isolates. Thirteen phenotypically erythromycin-resistant isolates could not be characterised by using PCR-RFLP and MAMA-PCR. To the best of our knowledge, this study is the first report about resistance to antibiotics in thermophilic Campylobacter originating from chicken in Kenya

Materials and methods: Nasal and ocular discharges (n=6, tracheal swab (n=6, tracheal washing (n=4 and infraorbital sinus exudates (n=4 were collected aseptically from broiler chickens (n=10. To isolate A. paragallinarum, the clinical samples were cultured onto blood agar and chocolate agar enriched with Nicotinamide Adenine Dinucleotide (NAD and feeder organism (Staphylococcus aureus. Identification of A. paragallinarum was performed by Gram staining reaction, sugar fermentation profiles using five basic sugars (Dextrose, Maltose, Sucrose, Lactose and Mannitol and biochemical tests (Indole, Voges Proskauer and Methyl red tests. Antibiogram of the bacterial isolates of infected chicken was performed against five antibiotics namely Ciprofloxacin, Azithromycin, Gentamicin, Ampicillin and Cefalexin using disk diffusion method. Results: Results of colonial morphology, Gram staining reaction, sugar fermentation and biochemical tests confirmed one isolate as A. paragallinarum. The overall prevalence of IC in broiler chicken was 10% (1 of 10. This isolate was found to be sensitive to Ciprofloxacin, Azithroycin and Gentamicin and resistant to Ampicillin and Cefalexin. Conclusion: This is the first report of detection of A. paragallinarum from broiler chicken in Bangladesh. [J Adv Vet Anim Res 2016; 3(2.000: 173-177

    This study was undertaken to determine whether changes had occurred in the numbers of burns that could be related to backyard burning subsequent to the introduction of the council tax throughout Eire for the collection of household refuse. Numbers of patients admitted to our unit who had sustained burns by burning rubbish were recorded prospectively over a period of 12 months. A random control group was taken as three years prior to this and results found by retrospective chart review. Between January and November 2005, 168 patients were admitted to the National Burns Unit, St James's Hospital Dublin, Ireland. Nineteen of these patients sustained flame burns from backyard burning. One hundred and seventy patients were admitted in the comparative period of 2002; Seven of these from backyard burning. The total number of inpatient days for these patients in 2005 (255) was significantly more than in 2002 (68) (p=0.024). The numbers in our study show a marked increase in the number of patients sustaining burns in this manner, and appear to correlate with the introduction of bin charges by a number of county councils around the country last year. This study demonstrates that the introduction of legislation can have an unforeseen adverse affect on the population if not introduced in correlation with appropriate public education. While the introduction of waste charges represents a very necessary move forward in waste disposal in Ireland, public awareness campaigns should be implemented to prevent further such injuries from occurring.

    2016-07-01

    Full Text Available Salmonella is considered as a global problem ranking first among food borne diseases. All motile Salmonella of poultry origin are zoonotic and readily transmit to human via meat and eggs but reports on non - typhoidal Salmonella serovars circulating in layer chickens is very limited in South-East Asian countries including Bangladesh. Salmonella serovars isolated from apparently healthy chickens were characterized in the present study. Of 170 samples (cloacal swab 150 and feed 20 collected from commercial layer farms, motile Salmonella was isolated 4% (6/150 and 50% (10/20 respectively by cultural, biochemical, motility test and by detection of hisJ gene. About 5% (8/170 samples possessed serovar-specific gene fimA, suggesting that isolates were Salmonella enterica serovar Typhimurium. Antimicrobial susceptibility testing demonstrated that the isolated serovars were multidrug resistant. Therefore apparently healthy layer chickens harbour and transmit S. Typhimurium to the environment, although little is alarming since it has zoonotic significance and the isolates were resistant to commonly used first line of antibiotic in Salmonella infection.

    Full Text Available Pasteurella multocida type A is the etiologic agent of fowl cholera, a highly contagious and fatal disease of chickens. The present research work was performed for the isolation, identification and molecular detection of P. multocida Type A from chickens. Liver, heart and spleen of suspected dead chicken (n=35 were collected from Gazipur and Pabna districts in Bangladesh. The targeted bacteria from the samples were isolated, identified and characterized based on their morphology, staining, cultural, biochemical characters, pathogenicity test, histopathological study and Polymerase Chain Reaction (PCR. The P. multocida organism was isolated from 11.42% (n=4/35 samples. The organisms were gram negative, non-spore forming rod, non-motile, occurring singly or pairs in Gram staining, whereas in Leishman's stain, bipolar shaped organisms were observed. All the isolates were found positive for oxidase and catalase tests, produced indole, and fermented glucose, mannitol and sucrose. Necrotic foci in liver and congestion with hemorrhages in heart were found on necropsy. After pathogenicity test, the pathological changes were reconfirmed by histopathology depicting congestion, hemorrhage and lymphocyte infiltration in heart, liver and spleen tissues. In type specific PCR reaction, the organisms were confirmed as P. multocida Type A. In conclusion, P. multocida type A is prevalent among poultry in the studied regions; thus, care must be taken to control of the disease. [J Adv Vet Anim Res 2015; 2(3.000: 338-345

    The spread of the highly pathogenic avian influenza (HPAI) H5N1 virus among poultry and humans has raised global concerns and has motivated government and public health organizations to initiate interventions to prevent the transmission of HPAI. In Bangladesh, H5N1 became endemic in poultry and seven human H5N1 cases have been reported since 2007, including one fatality. This study piloted messages to increase awareness about avian influenza and its prevention in two rural communities, and explored change in villagers' awareness and behaviors attributable to the intervention. During 2009-10, a research team implemented the study in two rural villages in two districts of Bangladesh. The team used a focused ethnographic approach for data collection, including informal interviews and observations to provide detailed contextual information about community response to a newly emerging disease. They collected pre-intervention qualitative data for one month. Then another team disseminated preventive messages focused on safe slaughtering methods, through courtyard meetings and affixed posters in every household. After dissemination, the research team collected post-intervention data for one month. More villagers reported hearing about 'bird flu' after the intervention compared to before the intervention. After the intervention, villagers commonly recalled changes in the color of combs and shanks of poultry as signs of avian influenza, and perceived zoonotic transmission of avian influenza through direct contact and through inhalation. Consequently the villagers valued covering the nose and mouth while handling sick and dead poultry as a preventive measure. Nevertheless, the team did not observe noticeable change in villagers' behavior after the intervention. Villagers reported not following the recommended behaviors because of the perceived absence of avian influenza in their flocks, low risk of avian influenza, cost, inconvenience, personal discomfort, fear of being

    Raising backyard chickens is an ever-growing hobby in the United States. These flocks can be a substrate for respiratory disease amplification and transmission to commercial facilities. Five hundred fifty-four chickens from 41 backyard flocks were sampled in this study. ELISA kits were used to detect antibodies against avian influenza (AI), infectious laryngotracheitis (ILT), Newcastle disease (ND), infectious bronchitis (IB), Ornithobacterium rhinotracheale (ORT), Mycoplasma gallisepticum (MG), and Mycoplasma synoviae (MS). All visited flock owners answered a biosecurity questionnaire that assessed biosecurity measures. The questionnaire revealed that backyard poultry owners lack simple biosecurity measures such as use of dedicated shoes, their chicken sources are unreliable, and few of them benefit from veterinary oversight. Only one flock had a clear vaccination history against ND and IB. ORT, ND, IB, MS, MG, and ILT were the most seroprevalent in backyard poultry flocks with 97% (41/42), 77.5% (31/40), 75% (30/40), 73% (31/42), 69% (29/42), and 45% (19/42), respectively. The vaccinated flock was not considered in these calculations. When examining the distance between backyard flocks and the nearest commercial poultry facility, ND and MG were significantly more likely to be found in backyard flocks close to (4 miles) commercial poultry. Birds purchased directly from National Poultry Improvement Plan hatcheries showed a reduced ND, MG, and MS antibody prevalence. Wearing dedicated shoes decreased MS antibody-positive birds. Finally, history of wild bird contact had a clear effect on an increased seroprevalence of NDV and MG. Serological results suggest that backyard poultry flocks have the potential to serve as a reservoir or amplifier for poultry respiratory diseases. The information generated in this project should direct extension efforts toward emphasizing the importance of small flock biosecurity and chick acquisition sources.

    In Cambodia, most poultry are raised in backyard flocks with a low level of biosecurity, which increases the risk of spread of infectious diseases. The aim of this study was to evaluate the effectiveness of a practical biosecurity intervention based on affordable basic measures. A cluster randomised trial was conducted in 18 villages in Cambodia from November 2009 to February 2011. Generalised estimating equations were used to test the association between the intervention and mortality rates in flocks of chickens and ducks. Mortality rates in chicken flocks in intervention villages (mean 6.3%, range 3.5-13.8%, per month) were significantly higher than in control villages (mean 4.5%, range 2.0-9.7%, per month; Pbiosecurity intervention implemented in this study was not associated with improvements in poultry mortality rates. These findings suggest that basic biosecurity measures may not suffice to limit the spread of infectious diseases in backyard poultry flocks in Cambodia. Copyright © 2013 Elsevier Ltd.

    Infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV) are economically important viral pathogens infecting chickens globally. Identification of endemic IBV and aMPV strains promotes better control of both diseases and prevents production losses. Orophrayngeal swab samples were taken from 2317 birds within 243 different backyard flocks in Oman. Swabs from each flock were examined by RT-PCR using part-S1 and G gene primers for IBV and aMPV respectively. Thirty-nine chicken flocks were positive for IBV. Thirty two of these were genotyped and they were closely related to 793/B, M41, D274, IS/1494/06 and IS/885/00. 793/B-like IBV was also found in one turkey and one duck flock. Five flocks were positive for aMPV subtype B. Though no disease was witnessed at the time of sampling, identified viruses including variant IBV strains, may still pose a threat for both backyard and commercial poultry in Oman.

    Two outbreaks of fowl cholera in the avifauna in Denmark, affecting primarily eiders but also cormorants, gulls and oyster-catchers were shown to be caused by the same clone of Pasteurella multocida ssp. multocida by restriction enzyme analysis (REA) and ribotyping, using the enzymes HpaII and HhaI and phenotypic characterization. This observation indicated spread by migratory birds. It was shown that the outbreak clone was closely related to isolates of Pasteurella multocida ssp. multocida obtained from back-yard poultry in Denmark, including chickens, pheasants, turkeys and ducks. The only detectable difference between the outbreak clone and some of these strains concerned the size of one fragment. These results indicate a possible exchange of P. multocida ssp. multocida between populations of wild birds and back-yard poultry. Among the DNA fingerprinting methods used, restriction enzyme analysis offered the highest discrimination among thirty strains obtained from back-yard poultry. The restriction enzymes HpaII and HhaI generated almost the same number of profile types, 17 and 15 respectively, but only HpaII differentiated the outbreak clone from the group of closely related strains isolated from back-yard poultry. Ribotyping, using the same enzymes, resulted in 12 and 10 different profile types, respectively. The outbreak isolates did not harbour any plasmids, while six out of the 30 strains originating from back-yard poultry (20%) carried a cryptic plasmid of approximately 3.4 kb.

    Since its first report in 2007, avian influenza (AI) has been endemic in Bangladesh. While live poultry marketing is widespread throughout the country and known to influence AI dissemination and persistence, trading patterns have not been described. The aim of this study is to assess poultry trading practices and features of the poultry trading networks which could promote AI spread, and their potential implications for disease control and surveillance. Data on poultry trading practices was collected from 849 poultry traders during a cross-sectional survey in 138 live bird markets (LBMs) across 17 different districts of Bangladesh. The quantity and origins of traded poultry were assessed for each poultry type in surveyed LBMs. The network of contacts between farms and LBMs resulting from commercial movements of live poultry was constructed to assess its connectivity and to identify the key premises influencing it. Poultry trading practices varied according to the size of the LBMs and to the type of poultry traded. Industrial broiler chickens, the most commonly traded poultry, were generally sold in LBMs close to their production areas, whereas ducks and backyard chickens were moved over longer distances, and their transport involved several intermediates. The poultry trading network composed of 445 nodes (73.2% were LBMs) was highly connected and disassortative. However, the removal of only 5.6% of the nodes (25 LBMs with the highest betweenness scores), reduced the network's connectedness, and the maximum size of output and input domains by more than 50%. Poultry types need to be discriminated in order to understand the way in which poultry trading networks are shaped, and the level of risk of disease spread that these networks may promote. Knowledge of the network structure could be used to target control and surveillance interventions to a small number of LBMs.

Test how binary star systems evolve under Einsteins general theory of relativity!Unusual VariablesCataclysmic variables irregularly brightening binary stars consisting of an accreting white dwarf and a donor star are a favorite target among amateur astronomers: theyre detectable even with small telescopes, and theres a lot we can learn about stellar astrophysics by observing them, if were patient.Diagram of a cataclysmic variable. In an AM CVn, the donor is most likely a white dwarf as well, or a low-mass helium star. [Philip D. Hall]Among the large family of cataclysmic variables is one unusual type: the extremely short-period AM Canum Venaticorum (AM CVn) stars. These rare variables (only 40 are known) are unique in having spectra dominated by helium, suggesting that they contain little or no hydrogen. Because of this, scientists have speculated that the donor stars in these systems are either white dwarfs themselves or very low-mass helium stars.Why study AM CVn stars? Because their unusual configuration allows us to predict the behavior of their orbital evolution. According to the general theory of relativity, the two components of an AM CVn will spiral closer and closer as the system loses angular momentum to gravitational-wave emission. Eventually they will get so close that the low-mass companion star overflows its Roche lobe, beginning mass transfer to the white dwarf. At this point, the orbital evolution will reverse and the binary orbit will expand, increasing its period.CBA member Enrique de Miguel, lead author on the study, with his backyard telescope in Huelva, Spain.

    Surveillance of influenza virus in humans and livestock is critical, given the worldwide public health threats and livestock production losses. Livestock farming involving close proximity between humans, pigs and poultry is often practised by smallholders in low-income countries and is considered an important driver of influenza virus evolution. This study determined the prevalence and genetic characteristics of influenza A virus (IAV) in backyard pigs and poultry in Cambodia. A total of 751 animals were tested by matrix gene-based rRT-PCR, and influenza virus was detected in 1.5% of sampled pigs, 1.4% of chickens and 1.0% of ducks, but not in pigeons. Full-length genome sequencing confirmed triple reassortant H3N2 in all IAV-positive pigs and various low pathogenic avian influenza subtypes in poultry. Phylogenetic analysis of the swine influenza viruses revealed that these had haemagglutinin and neuraminidase genes originating from human H3N2 viruses previously isolated in South-East Asia. Phylogenetic analysis also revealed that several of the avian influenza subtypes detected were closely related to internal viral genes from highly pathogenic H5N1 and H9N2 formerly sequenced in the region. High sequence homology was likewise found with influenza A viruses circulating in pigs, poultry and wild birds in China and Vietnam, suggesting transboundary introduction and cocirculation of the various influenza subtypes. In conclusion, highly pathogenic subtypes of influenza virus seem rare in backyard poultry, but virus reassortment, involving potentially zoonotic and pandemic subtypes, appears to occur frequently in smallholder pigs and poultry. Increased targeted surveillance and monitoring of influenza circulation on smallholdings would further improve understanding of the transmission dynamics and evolution of influenza viruses in humans, pigs and poultry in the Mekong subregion and could contribute to limit the influenza burden. © 2016 Blackwell Verlag GmbH.

    Full Text Available In this research, Sivas province divided into four agro-ecological zones (I, II, III and IV in terms of climate, land form, soil type and land cover. The face-to-face interviews were conducted with a total of 663 families in the 85 villages in order to determine the general structure of backyard poultry in the Sivas. Although women are determined as the primary factor at the rate of 65.6% in feeding-watering, they have a role in the product sales only 34.0% while man have 57.8%. The hens of agro–ecological zones are grouped as white, brown, black, and mixed according to feather colour and the average values of regions are calculated as 3.40, 4.78, 4.25, and 3.85 units/farm, respectively. Significant differences were found between regions in terms of the number of mixed coloured and brown coloured hens. Live weight and egg production were not affected by regional differences and mean live weight and egg weight was founded as 2.17 kg and 58.45 g, respectively. Egg production in the regions I, II, III and IV were determined as 82.35, 89.32, 64.13, and 78.66 units/year, respectively. There was no difference among the regions. It was determined that round type drinkers were used at the rate of 43.3%. Widely used cereal in feeding of chickens is wheat (89.9% followed by mixed feed (5.3%. The 41.24% of total eggs produced is consumed in the farm, 23.20% are served, and 33.57% are sold. Education and health studies to be conducted in the local backyard poultry will help in the short term to the achievement of the organic standards.

    Little is known concerning the seroprevalence of Toxoplasma gondii infection in chickens (Gallus domesticus) in Mexico. Antibodies to T. gondii were determined in 519 chickens in Durango, Mexico using the modified agglutination test (MAT). Two groups (A, B) of chickens were sampled. Group A chickens (n  =  51) were raised in backyards in 7 municipalities in 3 geographical regions in Durango State. Group B chickens were raised in farms in the Mexican States of Sinaloa (n  =  289) and Nayarit (n  =  179) but slaughtered in 2 abattoirs in Durango City. Overall, antibodies to T. gondii were found in 36 (6.9%) of 519 chickens, with MAT titers of 1∶25 in 22, 1∶50 in 8, 1∶100 in 2, 1∶200 in 3, and 1∶400 in 1. Seroprevalence of T. gondii increased significantly with age and was significantly higher in Group A chickens than in Group B chickens. In Group A chickens, a 25.5% seroprevalence of T. gondii infection was found. Seropositive chickens were found in all 7 municipalities sampled. In Group B chickens, the seroprevalence of T. gondii infection was 4.9%. This is the first report of T. gondii infection in chickens in Durango State, Mexico.

    In February of 2017 our team launched a new citizen science project entitled Backyard Worlds: Planet 9 to scan the cosmos for fast moving stars, brown dwarfs, and even planets. This Zooniverse website, BackyardWorlds.org, invites anyone with a computer or smartphone to flip through WISE images taken over a several year baseline and mark any point source that appears to move. This “blinking technique” is the same that Clyde Tombaugh discovered Pluto with over 80 years ago. In the first few days of our program we recruited over 30,000 volunteers. After 3/4 of a year with the program we have completed 30% of the sky and our participants have identified several hundred candidate movers. These include (1) over 20 candidate Y-type brown dwarfs, (2) a handful of new co-moving systems containing a previously unidentified low mass object and a known nearby star, (3) over 100 previously missed M dwarfs, (4) and more than 200 candidate L and T brown dwarfs, many of which occupy outlier positions on reduced proper motion diagrams. Our first publication credited four citizen scientists as co-authors. The Backyard Worlds: Planet 9 project is both scientifically fruitful and empowering for any mind across the globe that has ever wanted to participate in a discovery-driven astronomy research project.

    Full Text Available Abstract: This article describes five outbreaks of swinepox in backyard pigs in Northeastern Brazil. It affected backyard pigs from herds of poor hygienic-sanitary conditions with severe fly and lice infestations. The morbidity ranged from 33.3 to 100% among affected herds, with mortality reaching up to 60%. The affected pigs developed multifocal to coalescent gray to white papules and blisters in the skin, with eventual eruptions, evolving to erosions and crusts. In addition to skin lesions, affected piglets presented apathy, anorexia and fever. The disease was auto-limiting, resolving within 15 to 25 days. Histological examination revealed proliferative and ulcerative vesiculopustular dermatitis with ballooning degeneration of epithelial cells, perivascular inflammatory infiltrates of lymphocytes, plasma cells, neutrophils, eosinophils and some macrophages in the dermis. Intracytoplasmic eosinophilic inclusions were consistently observed in keratinocytes. Total DNA extracted from fresh tissue fragments obtained from one outbreak and formalin-fixed, paraffin-embedded (FFPE tissue from the other four outbreaks was submitted to polymerase chain reaction (PCR for Swinepox virus (SWPV and Vaccinia virus (VACV. Genetic SWPV material was identified by PCR in fresh material from one outbreak. Nucleotide sequencing and phylogenetic analysis of the PCR amplicons (viral polymerase gene demonstrated 100% homology with sequences from SWPV. All tissues were PCR negative for VACV. Swine poxvirus is present in backyard pigs in Northeastern Brazil, indicating the need of including SWPV in the differential diagnosis of dermatitis in pigs.

    Salmonellosis is a public health concern in both the developed and developing countries. Although the majority of human non-typhoidal Salmonella enterica (NTS) cases are the result of foodborne infections or person-to-person transmission, NTS infections may also be acquired by environmental and occupational exposure to animals. While a considerable number of studies have investigated the presence of NTS in farm animals and meat/carcasses, very few studies have investigated the risk of NTS colonization in humans as a result of direct animal exposure. We investigated asymptomatic NTS colonization in 204 backyard chicken farms, 204 farmers and 306 matched individuals not exposed to chicken farming, in southern Vietnam. Pooled chicken faeces, collected using boot or handheld swabs on backyard chicken farms, and rectal swabs from human participants were tested. NTS colonization prevalence was 45.6%, 4.4% and 2.6% for chicken farms, farmers and unexposed individuals, respectively. Our study observed a higher prevalence of NTS colonization among chicken farmers (4.4%) compared with age-, sex- and location- matched rural and urban individuals not exposed to chickens (2.9% and 2.0%). A total of 164 chicken NTS strains and 17 human NTS strains were isolated, and 28 serovars were identified. Salmonella Weltevreden was the predominant serovar in both chickens and humans. NTS isolates showed resistance (20-40%) against tetracycline, chloramphenicol, sulfamethoxazole-trimethoprim and ampicillin. Our study reflects the epidemiology of NTS colonization in chickens and humans in the Mekong delta of Vietnam and emphasizes the need of larger, preferably longitudinal studies to study the transmission dynamics of NTS between and within animal and human host populations. © 2016 The Authors.

    Campylobacteriosis is a zoonotic disease which has a worldwide public health impact. The disease is endemic in Egypt; however, the epidemiology in animals and humans has not been fully characterized. The objective of this study was to compare the risk of Campylobacter faecal carriage in children exposed to Campylobacter-infected vs. non-infected backyard poultry and to identify risk factors for a backyard being classified as infected. A total of 103 households which owned backyard poultry were sampled from a rural community in Egypt. Within these households 379 poultry and 106 children were tested for C. jejuni and C. coli; 23·5% and 5·5% of poultry were positive for C. jejuni and C. coli, respectively. In the studied households; 12·3% of children were positive for C. jejuni, and 2·8% were positive for C. coli. Using logistic regression, households with poultry positive for C. jejuni had 3·86 (95% confidence interval 1·0-15·0) times the odds of having children positive for C. jejuni compared to those housed with poultry which all tested negative. Backyard poultry may present a transmission route of C. jejuni to children. Backyards with poor cleaning and disinfection, wet litter and manure disposed of within the backyard had increased odds of being positive for C. jejuni. Enhancing biosecurity and management in poultry backyards may reduce the risk of the disease.

    Little is known about Salmonella serovars circulating in backyard poultry and swine populations worldwide. Backyard production systems (BPS) that raise swine and/or poultry are distributed across Chile, but are more heavily concentrated in central Chile, where industrialized systems are in close contact with BPS. This study aims to detect and identify circulating Salmonella serovars in poultry and swine raised in BPS. Bacteriological Salmonella isolation was carried out for 1744 samples collected from 329 BPS in central Chile. Faecal samples were taken from swine, poultry, geese, ducks, turkeys and peacocks, as well as environmental faecal samples. Confirmation of Salmonella spp. was performed using invA-polymerase chain reaction (PCR). Identification of serovars was carried out using a molecular serotyping approach, where serogroups were confirmed by a multiplex PCR of Salmonella serogroup genes for five Salmonella O antigens (i.e., D, B, C1, C2-C3, and E1), along with two PCR amplifications, followed by sequencing of fliC and fljB genes. A total of 25 samples (1·4% of total samples) from 15 BPS (4·6 % of total sampled BPS) were found positive for Salmonella. Positive samples were found in poultry (chickens and ducks), swine and environmental sources. Molecular prediction of serovars on Salmonella isolated showed 52·0% of S. Typhimurium, 16·0% of S. Infantis, 16·0% S. Enteritidis, 8·0% S. Hadar, 4·0% S. Tennessee and 4·0% S. Kentucky. Poor biosecurity measures were found on sampled BPS, where a high percentage of mixed confinement systems (72·8%); and almost half of the sampled BPS with improper management of infected mortalities (e.g. selling the carcasses of infected animals for consumption). Number of birds other than chickens (P = 0·014; OR = 1·04; IC (95%) = 1·01-1·07), mixed productive objective (P = 0·030; OR = 5·35; IC (95%) = 1·24-27·59) and mixed animal replacement origin (P = 0017; OR = 5·19; IC (95%) = 1·35-20·47) were detected as

    Cancer is predicted to be an increasingly important cause of morbidity and mortality in Bangladesh in the next few decades. The estimated incidence of 12.7 million new cancer cases will rise to 21.4 million by 2030. More than two-thirds of the total expenditure on health is through out-of-pocket payments. According to the Bangladesh Bureau of Statistics, cancer is the sixth leading cause of death. International Agency for Research on Cancer has estimated cancer-related death rates in Bangladesh to be 7.5% in 2005 and 13% in 2030. The two leading causes are in males are lung and oral cancer and in females are breast cancer and cervical cancer. Bangladesh is now in severe shortage of radiation therapy machines, hospital bed, trained oncologists, medical radiation physicists and technologists. Bangladesh having different cancers associated with smoking and smokeless tobacco use, Human papilloma virus infection, Hepatitis B and C infection, Helicobacter Pylori infection, arsenic contaminated groundwater, availability of chemical carcinogens mainly formalin treated fruits, fish and vegetables at open market, tannery waste contaminated with chromium (which is used for poultry feed and fish feed preparation). A World Health Organization study revealed the annual cost of illnesses in Bangladesh attributable to tobacco usage is US$ 500 million and the total annual benefit from the tobacco sector is US$ 305 million as tax revenue. Bangladesh has developed a National Cancer Control Strategy and Action Plan with the aim of delivering a universal, quality-based and timely service. Cancer prevention through tobacco control, health promotion and vaccination program, cancer early detection program for oral cavity, breast and cervix has initiated. Cancer detection and diagnostic facilities will be made available at medical colleges and district- hospitals and establish a referral chain. National capacity development, more cancer research will allow Bangladesh to deal effectively

    This study reports the first evidence of circulation of avian influenza viruses (AIV) in domestic poultry in Mali. In the Mopti region, where AIV have already been isolated in migratory water birds, we sampled 223 backyard domestic birds potentially in contact with wild birds and found that 3.6% had tracheal or cloacal swabs positive by real-time reverse transcription PCR (rRT-PCR) for type A influenza viruses (IVA) and that 13.7% had sera positive by commercial ELISA test detecting antibodies against IVA. None of the birds positive by rRT-PCR for IVA was positive by rRT-PCR for H5 and H7 subtypes, and none showed any clinical signs therefore indicating the circulation of low pathogenic avian influenza. Unfortunately, no virus isolation was possible. Further studies are needed to assess the temporal evolution of AIV circulation in the Mopti region and its possible correlation with the presence of wild birds.

    This book is for the aging amateur astronomy population, including newcomers to astronomy in their retirement and hobbyists who loved peering through a telescope as a child. Whether a novice or an experienced observer, the practice of astronomy differs over the years. This guide will extend the enjoyment of astronomy well into the Golden Years by addressing topics such as eye and overall health issues, recommendations on telescope equipment, and astronomy-related social activities especially suited for seniors. Many Baby-Boomers reaching retirement age are seeking new activities, and amateur astronomy is a perfect fit as a leisure time activity. Established backyard astronomers who began their love of astronomy in their youth , meanwhile, may face many physical and mental challenges in continuing their lifelong hobby as they age beyond their 55th birthdays. That perfect telescope purchased when they were thirty years old now suddenly at sixty years old feels like an immovable object in the living room. The 20...

  12. Backyard Worlds: Finding Nearby Brown Dwarfs Through Citizen Science

    Science.gov (United States)

    Kuchner, Marc

    Recent discoveries of cool brown dwarfs in the solar neighborhood and microlensing surveys both point to an undiscovered population of brown dwarfs and rogue planets in the solar neighborhood. We propose to develop and sustain a novel website that enables a unique and powerful citizen-science based search for these and other high-proper-motion objects at 3.5 and 4.6 microns. Through this search, we have an opportunity to discover new ultracool Y dwarfs, crucial links between star formation and planet formation, and also the Sun's nearest neighbors-potentially a system closer than Proxima Centauri. NASA's Wide-field Infrared Survey Explorer mission (WISE) is nominally sensitive enough to detect a 250 K brown dwarf to > 6 pc and even a Jupiter analog to > 0.6 pc. However, high proper motion objects like these can easily be confused with variable stars, electronic noise, latent images, optical ghosts, cosmic ray hits, and so on in the WISE archive. Computer-based searches for high-proper motion objects falter in dense star fields, necessitating visual inspection all candidates. Our citizen science project, called "Backyard Worlds: Planet 9", remedies this problem by engaging volunteers to visually inspect WISE and NEOWISE images. Roughly 104,000 participants have already begun using a preliminary version of the site to examine time-resolved co-adds of unWISE-processed images, four epochs spanning 2010 to 2014. They have already performed more than 3.6 million classifications of these images since the site's launch on February 15, 2017. Besides seeking new brown dwarfs and nearby stars, this site is also the most sensitive all-sky WISE-based search for a planet orbiting the Sun beyond Pluto (sometimes called Planet Nine). Preliminary analysis data from the site has resulted in the discovery of 13 brown dwarf candidates including 6 T dwarfs. We obtained a spectrum of one of these candidates and published it in Astrophysical Journal Letters, with four citizen scientists

    Full Text Available Background: Rape is one of the silent brutal sexual offences in Bangladesh. Despite strong laws against it, the evil of rape continues to rise. Increasing trend of the silent cruel sexual offence (rape represents a major psychopath sexual disorder and public health problem and progress of the country. Objective: The aim of the study was to determine the pattern of alleged rape victims in a rural district of Bangladesh with the ultimate aim to create public awareness about the brutal crime. Materials and method: This retrospective study was carried out on 330 sexually assailed alleged rape victims’ report forms, who reported at Faridpur Medical College, Bangladesh from 2007 to 2011 for medical examination. Results: Among the study subjects maximum number (70.0% of alleged rape cases were under the age of 20 years. More than two-thirds (64.60% of the assailants were known to the victims, most of the incidents (64.20% occurred in the victims’ houses and nearby places. The study also revealed that minimum number of victims (14.20% reported within 24 hours for medical examination. Almost one fourth of the alleged rape cases were gang rape and no positive finding in favour of sexual intercourse was found in about three fourth (72.40% of cases. Conclusion: Public awareness about rape would be effective to report in due time with preserving the evidence of crime and modern techniques like DNA diagnosis may be of help to detect the assailant.

    1981-03-01

    The author participated in the family planning project in Bangladesh from August 1, 1977 to December 31, 1979. The population of Bangladesh was 81 million in 1977 with annual increase of 3%, and the government was aiming at zero population growth. The government guidelines emphasized family planning as an effort integrated with other community programs. The use of adult education classes, mass media, and agricultural field workers and the training of paramedical personnel were proposed. The project members' activities involved motivating the public to delay marriages, to space births and to limit the family size to two children (average family size 6.5 children) as well as distributing contraceptives, promoting IUD and sterilization. Sterilization campaign for women in DNN district, 30 km south of Dacca, was carried out as follows. The women who had signed up in advance arrived at the elementary school classroom, where 2 medical teams performed operations using the teachers' desks and the equipment rented from a hospital in Dacca. The general procedure involved a physical examination by a female doctor, checking blood pressure, changing into a brand new native gown, premedication by injection, total anesthesia and operation itself. The equipment was sterilized by boiling. The patients were carried on the stretchers to the other classroom where they recuperated, staying overnight on the straw mats on the mud floor. They went home on foot the next day. The shortage of food and resources, high unemployment rate and low standard of living are some of the social problems Bangladesh faces along with overpopulation.

    The Integrated Family Development Program (IFDP) in Bangladesh is expanding from the original project areas in Panchdona Union and Dhalian Union into four neighboring unions under the initiative of the Family Planning Association of Bangladesh (FPAB). The JOICFP-executed project entered its second cycle this year as part of the UNFPA-supported regional Capacity Building for Sustainable Community-based Reproductive Health/Family Planning (FP) Project Emphasizing Quality of Care. The community-based project has won wide acceptance from people at the grass roots who have helped fuel its expansion into other villages. In particular, villagers have welcomed the comprehensive approach of the project which integrates a range of components such as reproductive health including FP/maternal and child health (MCH), income-generating activities, skills and literacy education for women and children and primary health care including parasite control. The success of the project also convinced the Japanese Embassy in Bangladesh to extend funding under the Japanese government's Grant Assistance for Grass Roots Cooperation Projects. With the funds, FPAB will establish a Women's Multipurpose Training Center in Panchdona Union. The sum of US$68,157 was officially handed over to FPAB on March 29 by Japanese Ambassador Yoshikazu Kaneko. The center, which is to open within this year, will contribute to improving reproductive health and promoting the empowerment of women. Once completed, it will be used for such activities as training in health care, literacy and skills for income generation for women's empowerment. full text

    Influenza virus surveillance, poultry outbreak investigations and genomic sequencing were assessed to understand the ecology and evolution of low pathogenicity avian influenza (LPAI) A viruses in Bangladesh from 2007 to 2013. We analyzed 506 avian specimens collected from poultry in live bird markets and backyard flocks to identify influenza A viruses. Virus isolation-positive specimens (n = 50) were subtyped and their coding-complete genomes were sequenced. The most frequently identified subtypes among LPAI isolates were H9N2, H11N3, H4N6, and H1N1. Less frequently detected subtypes included H1N3, H2N4, H3N2, H3N6, H3N8, H4N2, H5N2, H6N1, H6N7, and H7N9. Gene sequences were compared to publicly available sequences using phylogenetic inference approaches. Among the 14 subtypes identified, the majority of viral gene segments were most closely related to poultry or wild bird viruses commonly found in Southeast Asia, Europe, and/or northern Africa. LPAI subtypes were distributed over several geographic locations in Bangladesh, and surface and internal protein gene segments clustered phylogenetically with a diverse number of viral subtypes suggesting extensive reassortment among these LPAI viruses. H9N2 subtype viruses differed from other LPAI subtypes because genes from these viruses consistently clustered together, indicating this subtype is enzootic in Bangladesh. The H9N2 strains identified in Bangladesh were phylogenetically and antigenically related to previous human-derived H9N2 viruses detected in Bangladesh representing a potential source for human infection. In contrast, the circulating LPAI H5N2 and H7N9 viruses were both phylogenetically and antigenically unrelated to H5 viruses identified previously in humans in Bangladesh and H7N9 strains isolated from humans in China. In Bangladesh, domestic poultry sold in live bird markets carried a wide range of LPAI virus subtypes and a high diversity of genotypes. These findings, combined with the seven year

The most frequently identified subtypes among LPAI isolates were H9N2, H11N3, H4N6, and H1N1. Less frequently detected subtypes included H1N3, H2N4, H3N2, H3N6, H3N8, H4N2, H5N2, H6N1, H6N7, and H7N9. Gene sequences were compared to publicly available sequences using phylogenetic inference approaches. Among the 14 subtypes identified, the majority of viral gene segments were most closely related to poultry or wild bird viruses commonly found in Southeast Asia, Europe, and/or northern Africa. LPAI subtypes were distributed over several geographic locations in Bangladesh, and surface and internal protein gene segments clustered phylogenetically with a diverse number of viral subtypes suggesting extensive reassortment among these LPAI viruses. H9N2 subtype viruses differed from other LPAI subtypes because genes from these viruses consistently clustered together, indicating this subtype is enzootic in Bangladesh. The H9N2 strains identified in Bangladesh were phylogenetically and antigenically related to previous human-derived H9N2 viruses detected in Bangladesh representing a potential source for human infection. In contrast, the circulating LPAI H5N2 and H7N9 viruses were both phylogenetically and antigenically unrelated to H5 viruses identified previously in humans in Bangladesh and H7N9 strains isolated from humans in China. In Bangladesh, domestic poultry sold in live bird markets carried a wide range of LPAI virus subtypes and a high diversity of genotypes. These findings, combined with the seven year

    Full Text Available Emergence and transmission of infectious diseases have an enormous impact on the poultry industry and present a serious threat to the health of humans and wild birds. Noncommercial poultry operations, such as backyard poultry facilities in China, are potential sources of virus exchange between commercial poultry and wild birds. It is particularly critical in wetland areas where backyard poultry have close contact with commercial poultry and migratory birds, therefore increasing the risk of contracting infectious diseases. To evaluate the transmission risks, a cross-sectional study was undertaken in the Poyang Lake area, China, involving 309 residents in the backyard poultry farms in three counties (Region A, B, and C of Jiangxi Province. We examined the backyard poultry population, poultry species, presence of poultry deaths from infectious diseases, food sources, and biosecurity practices. Region B ranked highest for biosecurity while region C ranked lowest. The risks of infectious diseases were assessed by adjusted odds ratio based on multivariate logistic regression analysis. Potential risk factors in the three regions of the study site were compared. In Region A, significant factor was contact of poultry with wild birds (OR: 6.573, 95% CI: 2.148-20.115, P=0.001. In Region B, the most significant factor was contact of poultry with neighboring backyard waterfowls (OR: 3.967, 95% CI: 1.555-10.122, P=0.004. In Region C, significant factors were poultry purchase from local live bird markets (OR: 3.740, 95% CI: 1.243-11.255, P=0.019, and contact of poultry with wild birds (OR: 3.379, 95% CI: 1.058-10.791, P=0.040. In summary, backyard poultry was significantly affected by neighboring commercial poultry and close contact with wild birds. The results are expected to improve our understanding of the transmission risks of infectious diseases in a typical backyard poultry environment in rural China, and address the need to improve local farming

    Poultry represents an important sector in animal production, with backyard flocks representing a huge majority, especially in the developing countries. In these countries, villagers raise poultry to meet household food demands and as additional sources of incomes. Backyard production methods imply low biosecurity measures and high risk of infectious diseases, such as Newcastle disease or zoonosis such as Highly Pathogenic Avian Influenza (HPAI).We reviewed literature on biosecurity practices for prevention of infectious diseases, and published recommendations for backyard poultry and assessed evidence of their impact and feasibility, particularly in developing countries. Documents were sourced from the Food and Agriculture Organization (FAO) website, and from Pubmed and Google databases. A total of 62 peer-reviewed and non-referred documents were found, most of which were published recently (after 2004) and focused on HPAI/H5N1-related biosecurity measures (64%). Recommendations addressed measures for flock management, feed and water management, poultry trade and stock change, poultry health management and the risk to humans. Only one general guideline was found for backyard poultry-related biosecurity; the other documents were drawn up for specific developing settings and only engaged their authors (e.g. consultants). These national guidelines written by consultants generated recommendations regarding measures derived from the highest standards of commercial poultry production. Although biosecurity principles of isolation and containment are described in most documents, only a few documents were found on the impact of measures in family poultry settings and none gave any evidence of their feasibility and effectiveness for backyard poultry. Given the persistent threat posed by HPAI/H5N1 to humans in developing countries, our findings highlight the importance of encouraging applied research toward identifying sustained and adapted biosecurity measures for

    In May 1998, representatives of Japan's mass media toured Bangladesh to learn about the country's reproductive health and population programs. The goal of the visit was for the journalists to spread information about the projects to their peers, to government officials, and parliamentarians responsible for allocations of foreign aid. The 1st stage of the visit involved meetings with program officials and organizers. In the 2nd stage, the journalists toured: 1) Matlab, where the International Center for Diarrhoeal Disease Research has been implementing an intensive family planning (FP) program; 2) the Panchdona IP area, where the Integrated Family Development Project is being conducted with funding from the Japanese government; 3) an FP office and satellite clinic; and 4) a site where voluntary organizations are providing FP/maternal-child health care. The journalists also learned about how micro-credit loans operate. Participating journalists reported that they were very impressed with the people of Bangladesh, and that they had gained a new understanding of the relationship between reproductive health and human rights.

    In Bangladesh, little is known about the genomic composition and antigenicity of highly pathogenic avian influenza A(H5N1) viruses, their geographic distribution, temporal patterns, or gene flow within the avian host population. Forty highly pathogenic avian influenza A(H5N1) viruses isolated from humans and poultry in Bangladesh between 2008 and 2012 were analyzed by full genome sequencing and antigenic characterization. The analysis included viruses collected from avian hosts and environmental sampling in live bird markets, backyard poultry flocks, outbreak investigations in wild birds or poultry and from three human cases. Phylogenetic analysis indicated that the ancestors of these viruses reassorted (1) with other gene lineages of the same clade, (2) between different clades and (3) with low pathogenicity avian influenza A virus subtypes. Bayesian estimates of the time of most recent common ancestry, combined with geographic information, provided evidence of probable routes and timelines of virus spread into and out of Bangladesh.

    It has been found that in general there is a reduction of rainfall in all the regions of Bangladesh in all the seasons - premonsoon, monsoon and post monsoon during El Nino years. It has also been observed that in strong El Nino year Bangladesh is not hit by a catastrophic flood or a catastrophic cyclone. In the past, occurrence of famines in this region of the world coincided with El Nino years. The years of weak El Nino or when the El Nino index is positive seem to be favourable for the occurrence of floods and cyclones in Bangladesh. A theory of the modulation of the monsoon in Bangladesh by the Walker circulation has been described in the paper. (author). 14 refs, 7 figs, 1 tab

    Full Text Available This study longitudinally investigated the association between Triatoma dimidiata infestation, triatomine infection with Trypanosoma cruzi and household/backyard environmental characteristics in 101 homesteads in Molas and Yucatan, Mexico, between November 2009 (rainy season and May 2010 (dry season. Logistic regression models tested the associations between insect infestation/infection and potential household-level risk factors. A total of 200 T. dimidiata were collected from 35.6% of the homesteads, mostly (73% from the peridomicile. Of all the insects collected, 48% were infected with T. cruzi. Infected insects were collected in 31.6% of the homesteads (54.1% and 45.9% intra- and peridomiciliary, respectively. Approximately 30% of all triatomines collected were found in chicken coops. The presence of a chicken coop in the backyard of a homestead was significantly associated with both the odds of finding T. dimidiata (OR = 4.10, CI 95% = 1.61-10.43, p = 0.003 and the presence of triatomines infected with T. cruzi (OR = 3.37, CI 95% = 1.36-8.33, p = 0.006. The results of this study emphasize the relevance of chicken coops as a putative source of T. dimidiata populations and a potential risk for T. cruzi transmission.

    Full Text Available Copy number variants (CNVs are polymorphisms which influence phenotypic variation and are an important source of genetic variability [1]. In Mexico the backyard poultry population is a unique widespread Creole chicken (Gallus gallus domesticus population, an undefined cross among different breeds brought to Mexico from Europe and under natural selection for almost 500 years [2-3]. The aim of this study was to investigate genomic variation in the Mexican chicken population using CNVs. A total of 256 DNA samples genotyped with Axiom® Genome-Wide Chicken Genotyping Array were used in the analyses. The individual CNV calling, based on log-R ratio and B-allele frequency values, was performed using the Hidden Markov Model (HMM of PennCNV software on the autosomes [4-5]. CNVs were summarized to CNV regions (CNVRs at a population level (i.e. overlapping CNVs, using BEDTools. The HMM detected a total of 1924 CNVs in the genome of 256 samples resulting, at population level, in 1216 CNV regions, of which 959 gains, 226 losses and 31 complex CNVRs (i.e. containing both losses and gains, covering a total of 47 Mb of sequence length corresponding to 5,12 % of the chicken galGal4 assembly autosome. A comparison among this study and 7 previous reports about CNVs in chicken was performed, finding that the 1,216 CNVRs detected in this study overlap with 617 regions (51% mapped by others studies.   This study allowed a deep insight into the structural variation in the genome of unselected Mexican chicken population, which up to now has not been never genetically characterized with SNP markers. Based on a cluster analysis (pvclust – R package on CNV markers the population, even if presenting extreme morphological variation, does not resulted divided in differentiated genetic subpopulations. Finally this study provides a CNV map based on the 600K SNP chip array jointly with a genome-wide gene copy number estimates in Mexican chicken population.

    In Bangladesh grain legumes are the protein meat substitute of the poor, and an integral part of the daily diet. Yet present yields cannot meet demand and every year about 25% of the country's grain legumes' requirements have to be imported at a cost of about US $23 million in hard-earned foreign exchange. This money could easily be saved by increasing production in the country. The Department of Technical Co-operation is sponsoring a programme, with technical support from the Joint FAO/IAEA Division, in Bangladesh to find ways of increasing yields of grain legumes using efficient strains of biofertilizers.

    Full Text Available The riparian rural cutover lands and backyards represent a sustainable alternative for the production of food and medicinal drugs to the traditional communities from the Amazon, especially with regard to products diversity and income generation. Considering the ecological and social functions of these spaces, this paper aims at analyzing the agrobiodiversity of these environments in the Boca Moa community, in the town of Cruzeiro do Sul, Acre, Brazil. Data collection was carried out through participative, formal, and inductive interviews following a semi-structured questionnaire with open questions, besides in loco visits. The rural cutover lands present many species at the same area, and manioc is the main product cultivated. The backyards have spatial arrangements of food species, with emphasis on fruits and vegetables, besides medicinal plants. Thus, both the backyards and rural cutover lands participate in the subsistence and income of riparian families from this community.

    In South America little is known regarding influenza virus circulating in backyard poultry and swine populations. Backyard productive systems (BPS) that breed swine and poultry are widely distributed throughout Chile with high density in the central zone, and several BPS are located within the "El Yali" (EY) ecosystem, which is one of the most important wetlands in South America. Here, 130 different wild bird species have been described, of them, at least 22 species migrate yearly from North America for nesting. For this reason, EY is considered as a high-risk zone for avian influenza virus. This study aims to identify if backyard poultry and swine bred in the EY ecosystem have been exposed to influenza A virus and if so, to identify influenza virus subtypes. A biosecurity and handling survey was applied and samples were collected from BPS in two seasons (spring 2013 and fall 2014) for influenza seroprevalence, and in one season (fall 2014) for virus presence. Seroprevalence at BPS level was 42% (95% CI:22-49) during spring 2013 and 60% (95% CI 43-72) in fall 2014. rRT-PCR for the influenza A matrix gene indicated a viral prevalence of 27% (95% CI:14-39) at BPS level in fall 2014. Eight farms (73% of rRT-PCR positive farms) were also positive to the Elisa test at the same time. One BPS was simultaneously positive (rRT-PCR) in multiple species (poultry, swine and geese) and a H1N2 virus was identified from swine, exemplifying the risk that these BPS may pose for generation of novel influenza viruses.

    1985-01-01

    Population growth trends in Bangladesh in the 1871-1981 period were analyzed, with emphasis on fertility and mortality differentials, to provide a basis for population planning. Following proclamation of British Imperial Rule in 1857, mortality rates in Bangladesh began to decline as a result of preventive measures against natural disasters such as draught and famine, but the fertility rate remained unaltered. The demographic pattern was unstable over time, reflecting the impact of the influenza epidemic of 1918-19, war, migration, and economic development. Population growth accelerated greatly during the 1961-74 period, when industrialization emerged and job opportunities were created in the urban centers. Economic hardship, food shortages, and the introduction of family planning curbed urban growth drastically and total growth to some extent in 1974-81. On the average, growth has been higher in the Dhaka and Chittagong Divisions of Bangladesh than in the Khulna and Rajshahi Divisions. Differences in population growth among the regions are attributable largely to internal and external migration. The regression polynomial model best fits past population trends in Bangladesh and can reproduce the observed population by 99.60%. This polynomial is most suitable for graduation and prediction of population trends.

  7. Seismicity and tectonics of Bangladesh

    Hossain, K.M.

    1989-05-01

    Northern and eastern Bangladesh and surrounding areas belong to a seismically active zone and are associated with the subduction of the Indian plate. The seismicity and tectonics have been studied in detail and the observations have been correlated to understand the earthquake phenomenon in the region. The morphotectonic behaviour of northern Bangladesh shows that it is deeply related to the movement of the Dauki fault system and relative upliftment of the Shillong plateau. Contemporary seismicity in the Dauki fault system is relatively quiet comparing to that in the Naga-Disang-Haflong thrust belt giving rise to the probability of sudden release of energy being accumulated in the vicinity of the Dauki fault system. This observation corresponds with the predicted average return period of a large earthquake (1897 type) and the possibility of M > 8 earthquake in the vicinity of the Dauki fault within this century should not be ruled out. The seismicity in the folded belt in the east follows the general trend of Arakan-Yoma anticlinorium and represents shallow and low-angled thrust movements in conformity with the field observation. Seismotectonic behaviour in the deep basin part of Bangladesh demonstrates that an intraplate movement in the basement rock has been taking place along the deep-seated faults causing relative upliftment and subsidence in the basin. Bangladesh has been divided into three seismic zones on the basis of morphotectonic and seismic behaviour. Zone-I has been identified as the zone of high seismic risk.

    1992-08-01

    Bangladesh has a population of nearly 108 million on a landmass of 143,998 sq km. The rate of population growth peaked at around 35 in the 1960s. The population increased from about 43 million in 1951 to 68 million in 1970 and to about 90 million in 1981. In 1976 a national policy for population control and family planning (FP) was announced which employed thousands of full-time field workers, and developed information, education, and motivation activities. The implementation strategy entailed the integration of health and FP, maternal child health (FP/MCH) service delivery systems at subdistrict (upazila) levels with a wide choice of contraceptive methods and expanded good quality services. Greater emphasis on MCH services included immunization, oral rehydration, and training of traditional birth attendants. Even if the goal of net reproductive rate of 1 is achieved by 2005, the population will rise to about 137 million by 2000. The Fourth 5 year Plan (1990-95) seeks to lower the growth rate from 2.15 in 1990 to 1.8% by 1995; to cut the crude birth rate of 34.5 live births/1000 people in 1990 to 30.1/1000 by 1995; and to reduce the crude death rate of 13.6/1000 population in 1990 to 11.9/1000 by 1995. The reduction of the total fertility rate from 4.30 in 1990 to 3.40 by 1995 would require increasing the contraceptive prevalence rate of 40% in 1991 to 50% in 1995. It is also planned to raise the number of the continuous users of contraceptives from 8.8 million in 1991 to 12.3 million acceptors by 1995.

    2015-11-01

    Full Text Available The populations of many small towns in South Africa continue to expand unmatched by parallel economic growth, entrenching high levels of poverty. The town of Vredendal, located close to the national route between Namibia and Cape Town in South Africa, is a West Coast development node and an emergent industrial and processing area that continues to attract an influx of people seeking economic opportunities. This is challenging the capacity of the local municipality, which has a waiting list for state-provided low-cost housing units, whilst the provision of adequate infrastructure to meet growing local need is also a developmental concern. In the suburb of Vredendal North this has resulted in the proliferation of unplanned informal dwellings in the backyards of formalised low-cost housing areas. Largely overlooked by urban researchers, little is known or understood about small town backyard populations. This prompted a brief study of Vredendal North backyard dwellers commissioned by the local municipality to identify their everyday hazards and livelihood vulnerabilities to inform future development planning. A community workshop identified critical development needs and suggested that backyard dwellers in small towns experience similar living conditions and hazards to those in the cities, although underlain by some unique differences.

    Radiation technology offers a very wide scope for utilisation and commercial exploitation in various field. All over the world, this technology is being favourably considered for different applications like radiation sterilisation of medical products, preservation of food by controlling the physiological processes for extending shelf-life and eradication of microbial and insect pests, radiation processing of polymeric materials and treatment of sewage sludge. Bangladesh Atomic Energy Commission has taken radiation processing programmes in a big way right from its inception. This paper describes the studies carried out by various research groups in Bangladesh Atomic Energy Commission mainly using Cobalt-60 gamma radiation. The investigation covers medical sterilisation, food preservation and development and modification of polymeric materials by gamma radiation. Both food preservation and radiation sterilisation of medical products are now being commercially carried out in the Gammatech facility as a joint venture company of BAEC and a private entrepreneur. Bangladesh is soon going to establish a full-fledged Tissue Bank to cater the needs of various tissue allografts for surgical replacement. Recently Government of Bangladesh has allocated US$ 1.00 million for strengthening of the Tissue Banking Laboratory. BAEC has made quite a good research contribution on vulcanization of natural rubber latex, wood plastic composites, surface coating curing, polymer modification etc. As a result of successful achievement of R and D activities in all these projects, a pilot plant project involving about US$ 4.00 million is under implementation at the Atomic energy Research Establishment campus of BAEC. In addition a project on 'National Polymer Centre' at a cost of US$ 2.00 million has already been approved. It is expected that work on radiation processing including commercialization will be accelerated with the implementation of these projects. The impact of radiation

  20. Hypertension in Bangladesh: a review

    Directory of Open Access Journals (Sweden)

    A.K.M. Monwarul Islam

    2012-05-01

    Full Text Available Hypertension (HTN is an increasingly important medical and public health problem. In Bangladesh, approximately 20% of adult and 40–65% of elderly people suffer from HTN. High incidence of metabolic syndrome, and lifestyle-related factors like obesity, high salt intake, and less physical activity may play important role in the pathophysiology of HTN. The association of angiotensin-converting enzyme (ACE gene polymorphism and low birth weight with blood pressure has been studied inadequately. Studies have found relationship between mass arsenic poisoning and HTN. Hypovitaminosis D presumably plays role in the aetiopathogenesis of HTN in Bangladeshi population. South Asians appear to respond to antihypertensive therapy in a similar manner to the Whites. The latest National Institute for Health and Clinical Excellence guideline advocates a calcium-channel blocker as step 1 antihypertensive treatment to people aged > 55 years and an ACE inhibitor or a low-cost angiotensin-II receptor blocker for the younger people. Calcium-channel blockers and beta-blockers have been found to be the most commonly prescribed antihypertensive drugs in Bangladesh. Non-adherence to the standard guidelines and irrational drug prescribing are likely to be important. On the other hand, non-adherence to antihypertensive treatment is quite high. At the advent of the new millennium, we are really unaware of our real situation. Large-scale, preferably, nation-wide survey and clinical research are needed to explore the different aspects of HTN in Bangladesh.

  1. Inequality in disability in Bangladesh.

    Md Ismail Tareque

    Full Text Available To investigate inequality in disability in Bangladesh.The study used both household level and individual level data from a large nationally representative data set, Bangladesh's Household Income and Expenditure Survey-2010. Principal component analysis was used to construct a wealth index based on household assets from household level data. Then, using data from 49,809 individuals aged 5 years and over, chi-square tests and logistic regression were performed to test the association between wealth level and disability.Women and older people are significantly more likely to report having disabilities than men and younger people. For middle and rich families, respectively, there is a 14 percent lower likelihood of reporting disabilities than for poor families. Changes in the probability of having disabilities are linear with increasing wealth. In addition, the study identifies some significant factors affecting disability, namely, age, sex, education, marital status, and place of residence including divisional differences.In Bangladesh, worse health among the poor argues for policies prioritizing this group while at the same time giving special attention to women and the elderly.

  3. Energy poverty in rural Bangladesh

    International Nuclear Information System (INIS)

    Barnes, Douglas F.; Khandker, Shahidur R.; Samad, Hussain A.

    2011-01-01

    Energy poverty is a well-established concept among energy and development specialists. International development organizations frequently cite energy-poverty alleviation as a necessary condition to reduce income poverty. Several approaches used to measure energy poverty over the past 20 years have defined the energy poverty line as the minimum quantity of physical energy needed to perform such basic tasks as cooking and lighting. This paper uses a demand-based approach to define the energy poverty line as the threshold point at which energy consumption begins to rise with increases in household income. At or below this threshold point, households consume a bare minimum level of energy and should be considered energy poor. This approach was applied using cross-sectional data from a comprehensive 2004 household survey representative of rural Bangladesh. The findings suggest that some 58 percent of rural households in Bangladesh are energy poor, versus 45 percent that are income poor. The findings also suggest that policies to support rural electrification and greater use of improved biomass stoves might play a significant role in reducing energy poverty. - Research Highlights: →We estimate energy poverty for rural Bangladesh adopting a demand-based approach. →Findings suggest that energy poverty does not necessarily follow the same pattern as income poverty. →Access to modern energy and efficient use of traditional energy help alleviate energy poverty. →Energy poverty indicator can help track the effectiveness of a wide range of energy policies.

  4. Income Disparities and the Global Distribution of Intensively Farmed Chicken and Pigs.

    Directory of Open Access Journals (Sweden)

    Marius Gilbert

    Full Text Available The rapid transformation of the livestock sector in recent decades brought concerns on its impact on greenhouse gas emissions, disruptions to nitrogen and phosphorous cycles and on land use change, particularly deforestation for production of feed crops. Animal and human health are increasingly interlinked through emerging infectious diseases, zoonoses, and antimicrobial resistance. In many developing countries, the rapidity of change has also had social impacts with increased risk of marginalisation of smallholder farmers. However, both the impacts and benefits of livestock farming often differ between extensive (backyard farming mostly for home-consumption and intensive, commercial production systems (larger herd or flock size, higher investments in inputs, a tendency towards market-orientation. A density of 10,000 chickens per km2 has different environmental, epidemiological and societal implications if these birds are raised by 1,000 individual households or in a single industrial unit. Here, we introduce a novel relationship that links the national proportion of extensively raised animals to the gross domestic product (GDP per capita (in purchasing power parity. This relationship is modelled and used together with the global distribution of rural population to disaggregate existing 10 km resolution global maps of chicken and pig distributions into extensive and intensive systems. Our results highlight countries and regions where extensive and intensive chicken and pig production systems are most important. We discuss the sources of uncertainties, the modelling assumptions and ways in which this approach could be developed to forecast future trajectories of intensification.

    Shigellosis in chickens was first reported in 2004. This study aimed to determine the pathogenicity of Shigella in chickens and the possibility of cross-infection between humans and chickens. The pathogenicity of Shigella in chickens was examined via infection of three-day-old SPF chickens with Shigella strain ZD02 isolated from a human patient. The virulence and invasiveness were examined by infection of the chicken intestines and primary chicken intestinal epithelial cells. The results showed Shigella can cause death via intraperitoneal injection in SPF chickens, but only induce depression via crop injection. Immunohistochemistry and transmission electron microscopy revealed the Shigella can invade the intestinal epithelia. Immunohistochemistry of the primary chicken intestinal epithelial cells infected with Shigella showed the bacteria were internalized into the epithelial cells. Electron microscopy also confirmed that Shigella invaded primary chicken intestinal epithelia and was encapsulated by phagosome-like membranes. Our data demonstrate that Shigella can invade primary chicken intestinal epithelial cells in vitro and chicken intestinal mucosa in vivo, resulting in pathogenicity and even death. The findings suggest Shigella isolated from human or chicken share similar pathogenicity as well as the possibility of human-poultry cross-infection, which is of public health significance.

    In Bangladesh, nomadic duck flocks are groups of domestic ducks reared for egg production that are moved to access feeding sites beyond their owners' village boundaries and are housed overnight in portable enclosures in scavenging areas. The objectives of this study were to measure the prevalence of influenza A virus RNA and H5-specific antibodies in nomadic ducks and to characterize nomadic duck raising practices in northeastern Bangladesh. We tested duck egg yolk specimens by competitive ELISA to detect antibodies against avian influenza A (H5) and environmental fecal samples by real-time reverse-transcription polymerase chain reaction (rRT-PCR) to detect influenza A virus RNA and H5 subtype. The median age of the ducks was 24 months (range: 8-36 months) and the median flock size was 300 ducks (range: 105-1100). Of 1860 egg yolk samples, 556 (30%, 95% confidence interval (CI): 28-32) were positive for antibodies against H5 and 58 flocks (94%) had at least one egg with H5-specific antibodies. Of 496 fecal samples, 121 (24%, 95% CI: 22-29) had detectable influenza A RNA. Thirty-three flocks (53%) had at least one fecal sample positive for influenza A RNA. Nomadic ducks in Bangladesh are commonly infected with avian influenza A (H5) virus and may serve as a bridging host for transmission of avian influenza A (H5) virus or other avian influenza A viruses subtypes between wild waterfowl, backyard poultry, and humans in Bangladesh. © 2016 The Authors.

  9. Recognizing child maltreatment in Bangladesh.

    1997-08-01

    Concern is increasing in Bangladesh over child abuse, neglect, and exploitation. Children from all walks of life are being treated at the Child Development Center (CDC) Dhaka Shishu Hospital for neurodevelopmental problems resulting from abuse and neglect. Efforts to protect children from sexual harassment result in girls being isolated at home or married at an early age. Some young brides are eventually abandoned and forced into prostitution. Early marriage reflects the lack of acknowledgement of a period of adolescence and the belief that puberty is a marker of adulthood. Many girls aged 8-16 are employed as live-in domestic servants, and many suffer sexual as well as emotional abuse. Garment factories, on the other hand, offer girls an escape from extreme poverty, domestic service, and early marriage but are threatened by forces that condemn child labor. Rather than ending such opportunities, employers should be encouraged to provide employees with educational and welfare facilities. The CDC seeks to explore the extent and depth of the problem of child abuse while recognizing the special circumstances at work in Bangladesh. It is also necessary to raise awareness of these issues and of the discrepancies between the law and cultural practices. For example, the legal marriage age of 18 years for a woman and 21 years for a man is often ignored. Additional forms of abuse receiving the attention of women's organizations and human rights groups include the trafficking of children. A network of concerned organizations should be created to work against the child abuse, neglect, and exploitation that Bangladesh has pledged to overcome by signing the UN Convention on the Rights of the Child.

    A questionnaire survey was conducted to assess the biosecurity and other practices of backyard poultry holdings and knowledge and practices of poultry keepers following an outbreak of highly pathogenic avian influenza (H5N1) virus in poultry in Thimphu city area, Bhutan. The study identified 62 backyard poultry holdings in 12 settlement areas, and the owners were subsequently interviewed. The birds are kept in a low-input low-output system, fed locally available scavenging feed base, and supplemented with food scraps and some grain. Although the birds are housed at night in a small coop to protect them against theft and predators, they are let loose during the day to scavenge in the homestead surroundings. This invariably results in mixing with other poultry birds within the settlement and wild birds, creating favorable conditions for disease spread within and between flocks. Moreover, the poultry keepers have a low level of knowledge and awareness related to the importance of biosecurity measures, as well as veterinary care of the birds and reporting systems. Of particular concern is that sick birds within backyard holdings may not be detected rapidly, resulting in silent spread of disease and increased risk of humans contacting the virus (e.g. HPAI) from infected poultry. Nevertheless, all the respondents have indicated that they know and practice hand washing using soap and water after handling poultry and poultry products, but rarely use face-masks and hand gloves while handling poultry or cleaning poultry house. This study highlights the importance of educating poultry keepers to improve the housing and management systems of poultry farming within the backyard holdings in the Thimphu city area in order to prevent future disease outbreaks.

    Full Text Available While the development of land for residential housing along the Swan and Canning Rivers in Perth, WA, Australia has reduced natural mosquito breeding sites, the role of backyard container breeding remains a relatively unknown factor. Local Governments responsible for these areas focus management and control efforts on low lying, tidally driven mosquito habitats to control Aedes vigilax (Skuse and Aedes camptorhynchus (Thomson mosquitoes in an effort to reduce both the nuisance and disease risk to residents. In spite of their efforts, Local Governments continue to receive complaints regarding mosquito nuisance, even when environmental conditions do not favor hatching and development of the two species in the Swan River tidal flats. In this study, 150 backyard inspections were conducted in the residential suburb of Bassendean, Perth, WA, Australia, situated in close proximity to the Swan River tidal plain. The occurrence and species composition of the mosquito fauna found in residential backyards was documented. Of the backyards inspected, 94% were found to possess containers capable of breeding mosquitoes, although only 3% contained mosquito larvae. Nine species of mosquito were collected from containers ranging in capacity from 0.05 to 50 L across the study area. Additionally, encephalitis virus surveillance trapping was conducted within residential properties and compared to the tidally driven natural habitat at Ashfield Flats and a tidally influenced brackish creekline at Bindaring Park. The species composition of the fauna at the three habitat types differed significantly, with Aedes notoscriptus (Skuse dominating residential lots and A. vigilax more prevalent at the saltmarsh site. Bindaring Park had an adult composition at the mid-point of these two habitats, reflecting its proximity to both the Swan River and residential lots.

    Control and eradication of classical swine fever (CSF) in countries with a high proportion of backyard holdings is a challenge. Conventional attenuated Chinese C-strain vaccines, though safe and effective, are difficult to use in backyard farms due to various practical reasons. The aim of this study was to evaluate the efficacy of the CSF oral bait vaccine in village backyard pig farms and to assess the farmers' knowledge on CSF and motivation on using oral vaccines. The pigs were fed the bait by the farmers themselves; one bait was given on day 0, followed by second bait on the next day. Seventy-three per cent (140 of 193 pigs) of vaccinated pigs had either a slight (2-fold-3-fold; 60 pigs) or significant (at least 4-fold; 80 pigs) increase of the antibody titre against CSFV. A significant increase of the antibody titres was mainly observed in pigs with no pre-vaccination titre (OR = 12, 95% CI = 4-40). The number of pigs with protective antibody titres (≥40) rose from 47 (24%) to 115 (60%) following vaccination. Only 30% of the farmers claimed to be familiar with CSF, although clinical signs they mentioned were rather unspecific and could relate to many other pig diseases. Most of the farmers claimed to be motivated to use oral vaccines if made available. The oral vaccine could be a substitute for the conventional attenuated CSF vaccines in areas where it is logistically difficult for veterinarians to visit. It may therefore be a useful tool to combat endemic CSF disease in regions where the disease continues to have a serious impact on the backyard farmers who depend on pig farming for their sustenance and livelihoods. © 2015 Blackwell Verlag GmbH.

    Full Text Available To identify the kind of avian diseases could be transmits the backyard turkeys to the Oaxaca's Coast wild life and poultry, a clinical sanitary evaluation was performed in backyard turkeys who grassing on places that could be contact with wild life, in three different ecosystems: cloud forest, medium jungle deciduous and palm trees. The evaluation was performed on six male turkeys with a year and a half old, six female with six months of age, and six poults with less of eight months of age. The laboratory tests included: necropsy for clinical diagnosis of diseases and for a hystopathological examination of tissues; Hemagglutination Inhibition Tests to diagnose Newcastle Disease and Avian Influenza. Serum Plate Agglutination Test to identify antibodies against Mycoplasma gallisepticum, Mycoplasma synoviae and Salmonella pullorum, ELISA to identify Infectious Bronchitis and Infectious Bursal Disease. In addition, laboratory analyses were done to find internal and external parasites. The frequency of diseases was estimated with descriptive statistics and the correlation between Ecosystem X Turkeys Age was calculated with Pearson's correlation coefficient. Was identify Avian Pox, antibodies from Newcastle Disease, Avian Influenza, Infectious Bronchitis, Infectious Bursal Disease; Fowl Typhoid, Colibacillocis, Staphylococcosis, Infectious Sinusitis, Infectious Synovitis. The internal parasites identified were Ascaridia gallinae, Eimeria dispersa, Eimeria meleagridis, Heterakis gallinae and Tetramenes sp; and the external parasite Dermanyssus gallinae. All the diseases and parasitic diseases are dangerous for the poultry and the wild life. A relationship exist between ecosystem and diseases at different ages in backyard turkeys.

    The study was undertaken to investigate the occurrence and to characterize the ESBL/beta-lactamase producing-Escherichia coli in healthy pigs of organized and backyard farms in West Bengal, India. Total 200 rectal swabs were collected randomly from healthy pigs maintained in four organized farms and 10 backyard farms (n=100 each) and 76 isolates were identified as E. coli from organized (48/100, 48%) and backyard pigs (28/100, 28%). Twelve E. coli isolates (6%) in the present study were detected to possess any of the ESBL/beta-lactamase genes studied. ESBL/beta-lactamase producers were isolated with significantly more frequency from backyard pigs than the organized farm pigs (p=0.026). Six of ESBL/beta-lactamase producing isolates were phenotypically confirmed as CTX-M producers and ten of them were confirmed as TEM/SHV producers. PCR and sequencing of the amplified product from representative isolates revealed the presence of blaCTX-M-9, blaSHV-12 and blaTEM-1. No unique combination of the studied beta lactamase genes for organized and backyard farm pig isolates was noted. The ESBL isolates belonged to O13, O55, O133, O153, O157, O158, O166, rough and OUT serogroups. The association of heat labile toxin (elt) (pbeta-lactamase producers from organized farm (Ak/Ex) and indigenous pigs (Ak/Ex/Te; Ak/CoT/G) showed a characteristic phenotypical antibiotic resistance pattern. Two pairs of isolates from organized and backyard farm pigs showed clonal relationship indicating a possible transmission between the farms which were situated adjacently. Thus the present study revealed backyard farm pigs as major source of ESBL/beta-lactamase producing-E. coli associated with STa and characteristic antibiotic resistance pattern in India.

    Full Text Available Thalia Field’s work, which she has described as an “ecology of questions,” inhabitsthe edges of genres, where she grows her verbal environments of researched materialanimated by her asking. Her most recent book, Bird Lovers, Backyard (New Directions,2010, spins itself from the twigs and strands and of terminologies ranging fromarchitecture to zoology as she tracks questions of language, behavior, and relationshipsbetween species. “Whose Umwelt is it anyway?” she asks in this extended study ofhuman behavior and the uses of language in how we interpret and shape the world forourselves and other life forms.Through this exploration of human contradictions and miscommunicationbetween species, Field makes a nest for an egg that is a question of possibilities—forBird Lovers, Backyard is also a kind of future studies for human potential, operating byway of past example, telling tales of what might amount to a “series of mistakes.”Kicking off this inquiry into what we might be, the book opens with an epigraph fromher young son that slyly functions as a kind of crossroads: “What if everyone in theworld wasn’t nice?” asks the child—a question that may serve as a hardnosed premisefor going forth into the world or as a challenge, a call to grow up.And here, for a reader looking, Field’s submerged Buddhist outlook catches thelight. For in her allegiance to an agile balance of “nichelessness,” Field keepsBuddhism—fitting its central idea of interdependent origination—as but one strand inthe weave of her influences. In the book’s third poem-essay “This Crime Has a Name,”which this paper will focus on, Tibetan Buddhist figures and ideas form a part of anecosystem that encompasses industrial design, biosemiotics, and Chinese logicianswherein she thinks through the displacement of sparrow by spaceman, asking whatextinction looks like and what our species might mean.

    This news article describes women's housing conditions, housing policy, and pilot programs to house poor women in Bangladesh. Although Bangladesh has a constitution that reinforces the equal status of women, in practice, men dominate and patrilineal customs determine inheritance and property rights. Religious affiliation also determines land tenure and inheritance. Muslim women can inherit 12.5% of their husband's property if there are children. 25% is inherited if wives are without children. Hindu women without sons can inherit their husband's property, but not parental property. Many families refuse to release property to women without a fight. Women, regardless of ownership of land, rarely control or use their land. The custom of requiring men to maintain wives during the marriage, and daughters until marriage, creates obstacles to women's decision making about property. Without collateral and other security women are unable to secure bank loans. Many women are also constrained by the requirement of male consent or guarantees for bank transactions. Banks do not have a gender responsive criteria for selecting loan recipients. The government does not provide sufficient housing to satisfy the growing housing needs due to population growth. Some housing is available from slum landlords. A National Housing Policy was formulated in 1993. Priority would be given to the housing needs of low income women in urban areas and women-headed households with income below the poverty line. The policy does not address the underlying factors that prevent equal access to housing for women. The government prepared a Human Settlement and Urban Development proposal for the Habitat II conference. The plan did not address gender issues. Special efforts are being made by nongovernmental groups to meet the housing needs of professional women and for some disadvantaged women.

    Live Bird Markets (LBMs) in Asian countries are considered as hubs for the spread and maintenance of different infectious diseases. In Bangladesh, LBMs are the major source of live and dressed poultry to consumers and until now only a few studies have been conducted targeting infectious agent status such as avian influenza virus (AIV) prevalence of LBMs in Bangladesh. Therefore, a cross sectional study was conducted using all 40 LBMs within the Chittagong Metropolitan Area (CMA) of Bangladesh targeting demographic information and hygienic status of LBMs in concurrence with AIV prevalence and its subtype distribution, as well as the associated risk factors for AIV. Pooled environmental swab samples were collected from 2 to 9 different sites per stall, with epidemiological data being obtained from a total of 290 stalls across 40 LBMs. The samples were evaluated by Real Time Reverse Transcriptase Polymerase Chain Reaction. The prevalence of AIV was 40% (95% CI: 20-60%; N=40) at a LBM level followed by 20.3% (CI: 10-30%, N=290) at a stall level. Specifically, the prevalence of H5, H7 and H9 subtypes at stall level were 2.8% (95% CI: 1-5%), 0% (CI: 0-1.3%) and 3.1% (CI: 1-6%), respectively. Generalized Estimating Equation model identified that the type of species sold (OR=2.5: Chicken and non-duck species versus Duck with other species), bird holding areas (OR=1.9: Cage versus Floor) and Hygienic score (OR=3.1: Score 3 or more versus score less than 3) as potential risk factors for the detection of AIV at stall level. These results suggest that housing chickens and ducks together in the stalls, birds kept on floors, and lack of adequate hygienic measures of the stall were the crucial factors for spreading AIV. This research outcome could be used to develop a proof-based program concerning environmental sanitation along with development of an effective surveillance system to reduce the AIV transmission through LBMs in Bangladesh.

    In community-based participatory research (CBPR), issues such as creating a setting where community members drive decisions and creating culturally relevant processes remain largely underachieved. The Backyard Initiative (BYI) provided the setting for implementing a community-centered collaborative research process. The BYI is a partnership between Allina Health, the Cultural Wellness Center (CWC), and community residents to improve health. To describe the unique community-centered method used in the 2013 BYI Community Health Survey (CHS) as a viable approach for collecting meaningful and valid health related data. With this approach, the community operates as the agent of change rather than the target. At the core was the BYI assessment team, which brought together conventional researchers and community members to collaboratively design, implement, analyze, interpret, and disseminate the CHS results. Focusing on the CHS, this structure and process permitted and facilitated important and difficult discussions about approach, content and outcomes of the research. We held seven sessions (239 participants). Participants were 37% African American/African and 34% Native American, 65% female, and 72% spoke English at home. Achievement of our recruitment goals, participation of groups typically underrepresented in research, and positive community feedback were indications that the BYI approach to survey research was successful. The BYI CHS community-centered methods built trust among research partners and participants, engaged populations often underrepresented in research, and collected meaningful data. Our success indicates that it is possible to co-design and implement a lengthy survey to inform future research and community activities.

    The Wide-field Infrared Survey Explorer (WISE) is a powerful tool for finding nearby brown dwarfs and searching for new planets in the outer solar system, especially with the incorporation of NEOWISE and NEOWISE-Reactivation data. However, so far, searches for brown dwarfs in WISE data have yet to take advantage of the full depth of the WISE images. To efficiently search this unexplored space via visual inspection, we have launched a new citizen science project, called “Backyard Worlds: Planet 9,” which asks volunteers to examine short animations composed of difference images constructed from time-resolved WISE coadds. We report the first new substellar object discovered by this project, WISEA J110125.95+540052.8, a T5.5 brown dwarf located approximately 34 pc from the Sun with a total proper motion of ˜0.″7 {{yr}}-1. WISEA J110125.95+540052.8 has a WISE W2 magnitude of W2=15.37+/- 0.09; our sensitivity to this source demonstrates the ability of citizen scientists to identify moving objects via visual inspection that are 0.9 mag fainter than the W2 single-exposure sensitivity, a threshold that has limited prior motion-based brown dwarf searches with WISE.

    Full Text Available Riemerella anatipestifer (RA is the causative agent of septicemic and exudative disease for a variety of bird species. Although RA had been isolated from chickens, whether can bring damages to them is not unrevealed yet. In this study, we report a flock of SanHuang chickens infected by RA with 15% morbidity and less than 8% mortality. The infection is further substantiated by case duplicate. The tested chickens demonstrate typical signs of pericarditis, air sacculitis and perihepatitis that are completely consistent with the field outbreak. The results suggest that RA is pathogenic to SanHuang chickens, which can then be theoretically and practicably incorporated into its infection spectrum.

    In Bangladesh there are several published papers on superficial mycoses. Deep mycoses are also recognized as an important emerging problem. Here, we estimate the annual incidence and prevalence of serious fungal infections in Bangladesh. Demographic data were obtained from world population reports and the data on TB and HIV extracted from the online publications on tuberculosis in Bangladesh and Asia Pacific research statistical data information resources AIDS Data HUB. All the published papers on fungal infections in Bangladesh were identified through extensive search of literature. We estimated the number of affected people from populations at risk and local epidemiological data. Bangladesh has a population of ∼162.6 million, 31% children and only 6% over the age of 60 years. The pulmonary TB caseload reported in 2014 was 119,520, and we estimate a prevalence of 30,178 people with chronic pulmonary aspergillosis, 80% attributable to TB. An anticipated 90,262 and 119,146 patients have allergic bronchopulmonary aspergillosis or severe asthma with fungal sensitization. Only 8,000 people are estimated to be HIV-infected, of whom 2900 are not on ART with a CD4 count Bangladesh. Candida bloodstream infection was estimated based on a 5 per 100,000 rate (8100 cases) and invasive aspergillosis based primarily on leukemia and COPD rates, at 5166 cases. Histoplasmosis was documented in 16 cases mostly with disseminated disease and presumed in 21 with HIV infection. This study constitutes the first attempt to estimate the burden of several types of serious fungal infections in Bangladesh.

    Full Text Available The chicken was domesticated in South Asia in 2000 BC and then spread around the world .The red jungle fowl (RJF, Gallus gallus was the ancestor of the chicken. In consequence of long years of domestication and breeding activities, chickens were scattered over various countries, continents and regions. As a result, today there are many chicken breeds in the world. Native breeds are thought to be crossbreds of various breeds brought to Turkey in different time periods. It is difficult to predict when and how the hybridization has been taken shape, because Anatolia has been a passage for a variety of tribes since ancient times. Indigenous chicken breeds in Turkey are Gerze, Sultan and the most well-known Denizli.

    The Bangladesh Social Marketing Project (SMP), providing contraceptives at an annual rate of 931,000 couple years of protection (CYP) as of June 1983, is a success. This figure has grown markedly since the start of the program in late 1975, when the SMP provided 80,000 CYPs, or 8% of nonclinical protection provided. The SMP has contributed to the steadily increasing national nonclinical contraceptive distribution. Currently, SMP distribution accounts for as much as the government and nongovernment programs combined. When clinical methods (including sterilizations) are added to national distribution, the SMP share represents about 28% of total contraceptive use. The SMP does not provide clinical methods, but the entire increase in nonclinical protection provided by the national program since 1975 has been the result of SMP product sales. The SMP utilizes the available mass media for promotion, including print, radio, television, as well as outdoor media and point of purchase materials. Mobile Film Units (MFUs) are an innovative promotional method employed by the SMP. Approximately 80 night time outdoor showings are organized each month in rural areas by SMP promoters. Typically, several short films, usually a popular story with a family planning theme, are run. Between each film the SMP products are of advertised. Products are often sold during and after the films. Retail outlets for SMP products include general stores, pharmacies, and other small shops. When products were introduced in 1975 retail outlets totaled 7500. By August 1983 the number of country wide retailers carrying SMP products had grown to nearly 100,000. In 1982 a marketing strategy emphasizing the role of doctors and rural medical practitioners (RMPs) was introduced. There are between 70,00-100,000 RMPs in Bangladesh. They are well known and respected "doctors" in their villages and add an extensive family planning outreach to the SMP system. The most important advantage of using the RMPs is their

    According to this statement presented to the Committee on Population of the UN Economic and Social Commission for Asia and the Pacific, the population of Bangladesh increased from 76.4 million in 1974 to 89.9 million in 1981 and if the annual estimated growth rate of 2.4% continues unchecked, the population will be 111.5 million by 1990. Rapid population growth increases the man-land ratio, while the undesirable age structure entails a high dependency burden and provides a large base for further population growth. The huge investment in food production is neutralized and educational facilities remain unavailable for most of the nation's 15.6 million school-age children. Even under the most optimistic population projection, the total will increase by more than 60% by the year 2015, exacerbating the already serious problems of poverty and unemployment. The urban population is expected to increase from 17.5 million at present to 37.3 million by 2000, including a multitude of squatters with no visible income-earning opportunities. The population policy adopted by the government in June 1976 was directed toward influencing demographic behavior primarily through information, education, and motivation activities and a wide array of family planning services provided at maternal-child health and family planning centers. The government has taken some steps to increase economic productivity and create employment, and has made administrative changes including upgrading the smallest administrative units and creating directorates for primary education and women's affairs. Health and population control strategies will include establishing primary health care and maternal-child health and family planning centers throughout the country, expanding the family planning worker to population ratio, and integrating the family planning programs with all development oriented programs. The National Council for Population Control and several other organizational structures have been created

    We aimed to determine the frequency of pH1N1 transmission between humans and swine on backyard farms in Tumbes, Peru. Two-year serial cross-sectional study comprising four sampling periods: March 2009 (pre-pandemic), October 2009 (peak of the pandemic in Peru), April 2010 (1st post-pandemic period), and October 2011 (2nd post-pandemic period). Backyard swine serum, tracheal swabs, and lung sample were collected during each sampling period. We assessed current and past pH1N1 infection in swine through serological testing, virus culture, and RT-PCR and compared the results with human incidence data from a population-based active surveillance cohort study in Peru. Among 1303 swine sampled, the antibody prevalence to pH1N1 was 0% pre-pandemic, 8% at the peak of the human pandemic (October 2009), and 24% in April 2010 and 1% in October 2011 (post-pandemic sampling periods). Trends in swine seropositivity paralleled those seen in humans in Tumbes. The pH1N1 virus was isolated from three pigs during the peak of the pandemic. Phylogenetic analysis revealed that these viruses likely represent two separate human-to-swine transmission events in backyard farm settings. Our findings suggest that human-to-swine pH1N1 transmission occurred during the pandemic among backyard farms in Peru, emphasizing the importance of interspecies transmission in backyard pig populations. Continued surveillance for influenza viruses in backyard farms is warranted. © 2015 The Authors. Influenza and Other Respiratory Viruses Published by John Wiley & Sons Ltd.

    Full Text Available Aim: In the present study, egg quality traits of endangered Nicobari fowl and its crosses (Nicorock and Nishibari were evaluated under intensive (deep litter as well as backyard system, in the regions of Andaman and Nicobar Islands, India. Materials and Methods: Fresh eggs (15 of all the three genetic groups of birds were collected randomly from institute farm (intensive system and from farmers’ field. The eggs were collected from adult birds (50 weeks of age 3 times with 5 in number in each time. All the genetic groups of birds were subjected to same husbandry practices. The eggs were subjected to external and internal quality parameters study. Results: The effect of genetic groups on egg weight was significant (p<0.05 for all the groups. Nicorock had significantly higher egg weight (g (56.79±0.77 in comparison to Nicobari (53.20±0.34 and Nishibari (48.98±0.22 under intensive system of management. Under backyard condition, the egg weight (g of Nicorock (48.60±1.04 was significantly higher than Nicobari but not with Nishibari. In general, the egg weight was found less under backyard system than intensive system that might be due to scavenging nature of birds. Egg length, egg width and shape index differed significantly (p<0.05 among the genetic groups. Yolk index of Nicorock was significantly (p<0.05 higher than Nishibari under intensive as well as backyard condition. The shell thickness varied significantly (p<0.05 among different genetic groups. Haugh unit of Nicorock was significantly (p<0.05 lower in comparison to Nicobari and Nishibari under intensive system, but did not vary significantly among genetic groups under backyard condition. Conclusions: The study revealed that there was a significant effect of genetic groups on different egg quality traits; both in intensive system and backyard condition.

    Avian influenza (H5N1) (AI) is becoming a serious public health threat in Egypt. The current study aimed to assess the existing knowledge, attitudes, and various practices regarding AI in household backyard poultry breeders residing in Fayoum Governorate, in rural Egypt. Of the 149 cases confirmed to date in Egypt, 51 have been fatal. This study was implemented in El Gendy and Manshat Abdllah villages in Fayoum Governorate. The latter village is the one in which a case of AI was confirmed in February 2007. A group of 150 women aged 15 years and above were recruited. A structured Arabic questionnaire was used to collect data. All interviewed women (N=150) had heard about AI. TV\\radio was the common source of information (83.3%). Nearly all interviewed women knew that AI is transmitted from birds to humans (99%). Most of the participants (>90%) correctly identified saliva, nasal secretions, feces, and contaminated vehicles as the modes of AI transmission. The knowledge regarding biosecurity measures (>70%) and measures of prevention (>90%) was generally good. More than 90% of the interviewed housewives agreed that AI is a serious disease that can be prevented, and that sanitary precautions during breeding and food preparation practices are effective measures for prevention of AI infection. Protective measures such as the use of gloves and masks, which minimize the risk of transmission of AI from poultry to humans, were seldom used by housewives in all their breeding, slaughtering, and cooking practices. However, washing hands either with water or with soap and water was reported by the vast majority of the respondents (>90%). There was a good level of knowledge and favorable attitude of the study participants regarding AI; however, practices appear to be inadequate to achieve full protection against AI. Comprehensive and multidisciplinary interventions should be widely used to enhance the complex behavior change process among the village residents.

    The emergence and spread of Highly Pathogenic Avian Influenza H5N1 has caused substantial poultry-related economic losses and public health concerns in relation to a potential pandemic. While biosecurity measures for commercial poultry industry are of the highest standards, these measures are difficult to implement and often unaffordable for backyard poultry farming, particularly in tropical and low-income settings. We designed a feasible biosecurity intervention to improve flock hygiene in Cambodia, - based on community hygiene, cleaning of poultry flock areas and human and poultry movement control. We conducted a cluster randomized and controlled intervention trial in 18 villages in Takeo province to evaluate improvements in biosecurity-related knowledge and practices. The intervention relied on community involvement and community education using special information dissemination tools. We trained village teams (VT) to assist villagers in implementing the intervention using a cascade training approach, in which a few individuals were trained, who in turn trained a larger group of people. During the 14 month follow up, we conducted observational and interview-based surveys (baseline vs. final surveys, VT supervision visits, monitoring surveys) to assess VTs' motivation, intervention messages dissemination and the implementation of recommended measures. Most of villagers (95%, confidence interval: 87.8-100.0%) in intervention villages received general information about how to raise poultry. Farmers in intervention villages reported to have made more changes (≥1 biosecurity related practice during the study period) compared with that of control villages (70.0% (260/372) vs. 22.6% (85/377), p valuebiosecurity-related practices in intervention villages, overall scores increased significantly (pbiosecurity practices in the community. However, further follow-ups are needed to assess whether practices-related changes persist over a longer period of time. Copyright

    Full Text Available Background: The paper examines the effect of child labour on child health outcomes in Bangladesh, advancing the methodologies and the results of papers published in different journals. Objective: We examine the effect of child labour on child health outcomes. Methods: We used Bangladesh National Child Labour Survey data for 2002-2003 for our analysis. Results: The main finding of the paper suggests that child labour is positively and significantly associated with the probability of being injured or becoming ill. Intensity of injury or illness is significantly higher in construction and manufacturing sectors than in other sectors. Health disadvantages for different age groups are not essentially parallel. Conclusions: The results obtained in this paper strengthen the need for stronger enforcement of laws that regulate child labour, especially given its adverse consequences on health. Although the paper focuses on Bangladesh, much of the evidence presented has implications that are relevant to policymakers in other developing countries.

    Data on the future electricity demand is an essential requirement for planning the expansion of a power system. The purpose of this study is to provide a general overview of electricity consumption in Bangladesh, forecast sector-wise electricity demand up to 2035 considering the base year 2005, and compare the results with official projections. The Long-range Energy Alternative Planning (LEAP) model with three scenarios, namely low gross domestic product (GDP) growth, average GDP growth and high GDP growth, is applied in this study. In the low to high GDP growth scenarios, the extent of industrial restructuring and technical advancement is gradually increased. The findings have significant implications with respect to energy conservation and economic development. The study also compares the projected per capita electricity consumption in Bangladesh with the historical growth in several other developing countries. Such an evaluation can create awareness among the planners of power system expansion in Bangladesh to meet the high future demand.

    The presence of lipoxygenase-type enzymes was demonstrated in chick muscles. Examination of the oxidation products of [ 14 C]arachidonic acid revealed the presence of 15-lipoxygenase. The enzyme was partially purified by affinity chromatography on linoleoyl-aminoethyl-Sepharose. The enzyme was stable on frozen storage, and activity was almost completely preserved after 12-month storage at -20 degree C. During this period the content of cis,cis-1,4-pentadiene fatty acids decreased slightly. It is suggested that lipoxygenase may be responsible for some of the oxidative changes occurring in fatty acids on frozen storage of chicken meat

    Ubydul Haque

    Full Text Available BACKGROUND: Following the 1971 ban of DDT in Bangladesh, malaria cases have increased steadily. Malaria persists as a major health problem in the thirteen south-eastern and north-eastern districts of Bangladesh. At present the national malaria control program, largely supported by the Global Fund for AIDS, Tuberculosis and Malaria (GFATM, provides interventions including advocacy at community level, Insecticide Treated Net (ITN distribution, introduction of Rapid Diagnostic Tests (RDT and combination therapy with Coartem. It is imperative, therefore, that baseline data on malaria prevalence and other malaria indicators are collected to assess the effectiveness of the interventions and rationalize the prevention and control efforts. The objective of this study was to obtain this baseline on the prevalence of malaria and bed net use in the thirteen malaria endemic districts of Bangladesh. METHODS AND PRINCIPAL FINDINGS: In 2007, BRAC and ICDDR,B carried out a malaria prevalence survey in thirteen malaria endemic districts of Bangladesh. A multi-stage cluster sampling technique was used and 9750 blood samples were collected. Rapid Diagnostic Tests (RDT were used for the diagnosis of malaria. The weighted average malaria prevalence in the thirteen endemic districts was 3.97%. In five south-eastern districts weighted average malaria prevalence rate was 6.00% and in the eight north-eastern districts weighted average malaria prevalence rate was (0.40%. The highest malaria prevalence was observed in Khagrachari district. The majority of the cases (90.18% were P. falciparum infections. Malaria morbidity rates in five south-eastern districts was 2.94%. In eight north-eastern districts, morbidity was 0.07%. CONCLUSION AND SIGNIFICANCE: Bangladesh has hypoendemic malaria with P. falciparum the dominant parasite species. The malaria situation in the five north-eastern districts of Bangladesh in particular warrants urgent attention. Detailed maps of the

  10. The Ri chicken breed and livelihoods in North Vietnam: characterization and prospects

    2011-06-01

    Full Text Available For the last twenty years, the consumption of poultry meat has boomed in Vietnam as in the rest of the developing world. Capital-intensive production has grown rapidly to satisfy this demand. Based on a few numbers of genetically uniform strains, these systems threaten biodiversity. In Vietnam, both rural and urban households still keep indigenous chickens as part of a diversified livelihood portfolio. In line with the national in situ conservation strategy, this study approached the context of local poultry keeping in two rural and one suburban districts of Northern Vietnam. It aimed at understanding households’ willingness, constraints and opportunities for practice improvement, including breeds’ management. As the Ri chicken constitutes the large majority of backyard flocks, two particular objectives of this study are the morpho-biometric characterisation of phenotypic diversity among individuals classified as Ri by farmers and an assessment of their productive potential. Chicken was found to hold a different place in livelihoods of the three districts with consequences on the management of genetic resources. The most favourable conditions for improvement of the Ri breed was found in the rural district of Luong-Son, due to market integration. In the more remote district of Ky-Son, living standards were lower and much would be gained from Ri conservation. Ri breed was the most threatened in the suburban Gia-Lam district, where poultry was a minor side-activity, lacking incentive for genetic management. From motives and constraints, tracks about breeding goals are suggested. Further considerations about conservation, improvement, market integration and livelihoods are proposed.

    Human infection with avian influenza A(H9N2) virus was identified in Bangladesh in 2011. Surveillance for influenza viruses in apparently healthy poultry in live-bird markets in Bangladesh during 2008–2011 showed that subtype H9N2 viruses are isolated year-round, whereas highly pathogenic subtype H5N1 viruses are co-isolated with subtype H9N2 primarily during the winter months. Phylogenetic analysis of the subtype H9N2 viruses showed that they are reassortants possessing 3 gene segments related to subtype H7N3; the remaining gene segments were from the subtype H9N2 G1 clade. We detected no reassortment with subtype H5N1 viruses. Serologic analyses of subtype H9N2 viruses from chickens revealed antigenic conservation, whereas analyses of viruses from quail showed antigenic drift. Molecular analysis showed that multiple mammalian-specific mutations have become fixed in the subtype H9N2 viruses, including changes in the hemagglutinin, matrix, and polymerase proteins. Our results indicate that these viruses could mutate to be transmissible from birds to mammals, including humans. PMID:23968540

    In 2013, a mortality event of nonnative, feral Rosy-faced Lovebirds (Agapornis roseicollis) in residential backyards in Maricopa County, Arizona, US was attributed to infection with Chlamydia psittaci. In June 2014, additional mortality occurred in the same region. Accordingly, in August 2014 we sampled live lovebirds and sympatric bird species visiting backyard bird feeders to determine the prevalence of DNA and the seroprevalence of antibodies to C. psittaci using real-time PCR-based testing and elementary body agglutination, respectively. Chlamydia psittaci DNA was present in conjunctival-choanal or cloacal swabs in 93% (43/46) of lovebirds and 10% (14/142) of sympatric birds. Antibodies to C. psittaci were detected in 76% (31/41) of lovebirds and 7% (7/102) of sympatric birds. Among the sympatric birds, Rock Doves (Columba livia) had the highest prevalence of C. psittaci DNA (75%; 6/8) and seroprevalence (25%; 2/8). Psittacine circovirus 1 DNA was also identified, using real-time PCR-based testing, from the same swab samples in 69% (11/16) of species sampled, with a prevalence of 80% (37/46) in lovebirds and 27% (38/142) in sympatric species. The presence of either Rosy-faced Lovebirds or Rock Doves at residential bird feeders may be cause for concern for epizootic and zoonotic transmission of C. psittaci in this region.

    In spite of the high prevalence of malaria in Southeastern Bangladesh, there remains a significant shortage of information regarding the presence of three of five human malaria parasites: Plasmodium ovale, P. malariae, and P. knowlesi. The presence of P. ovale and P. knowlesi has previously never been reported from Bangladesh. We used a genus- and species-specific nested polymerase chain reaction, targeting highly conserved regions of the small subunit ribosomal RNA (SSU rRNA) gene, to investigate the presence of malaria parasites in a total number of 379 patient samples in a survey of patients with febrile illnesses in the Chittagong Hill Tracts in Southeastern Bangladesh. We identified the first cases of P. ovale in Bangladesh. They were confirmed by sequence analysis; 189 of 379 samples (49.9%; 95% confidence interval = 44.9-54.9%) were positive for Plasmodium sp. by PCR. P. falciparum monoinfections accounted for 68.3% (61.3-74.5%), followed by P. vivax (15.3%; 10.9-21.2%), P. malariae (1.6%; 0.5-4.6%), P. ovale (1.6%; 0.5-4.6%), and mixed infections (13.2%; 9.1-18.8%). We found no evidence of P. knowlesi in this region.

  16. Pangolin distribution and conservation status in Bangladesh.

    Directory of Open Access Journals (Sweden)

    Scott J Trageser

    Full Text Available Asian pangolins are a highly-threatened species group, mainly due to the perceived medicinal value of their scales. Increased demand from China has resulted in pangolins being the most trafficked mammal in the world. Three pangolin species are reported to occur in Bangladesh: Manis pentadactyla, M. crassicaudata, and M. javanica. No peer-reviewed studies exist detailing these species' current distribution or status within Bangladesh. A literature review was conducted resulting in the clarification of conflicting reports and misidentified observations and specimen records. In this paper, we also report the current status of pangolins (Manis spp. in Bangladesh based on semi-structured interviews, camera trapping, media queries, and field surveys employing traditional ecological knowledge and non-randomized transect surveys. Ethnozoological knowledge pertaining to the natural history of M. pentadactyla is also reported from experienced Mro tribal hunters. The critically endangered M. pentadactyla was verified to occur in northwest, northeast, and southeast Bangladesh in natural and degraded habitats. Interviews with the Mro tribe in the southeast indicate that pangolin populations there were likely extirpated in 2014 due to skilled commercial collection beginning in 2010. Evidence of extant M. crassicaudata and M. javanica populations remain unverified and questionable, and historical records of M. crassicaudata and M. javanica are likely a result of misidentification.

    This study aimed to investigate the regional variations in the prevalence of child marriage in Bangladesh with a view to providing recommendations for division-specific policy interventions. Data from the 2011 Bangladesh Demographic and Health Survey were analysed using multivariate logistic regression. Substantial regional variations in child marriage were found in Bangladesh. Rangpur and Khulna had more than four times higher odds of child marriage than Sylhet (4.57 and 4.11 times, respectively). Barisal and Rajshahi had more than three times higher odds of child marriage than Sylhet (3.70 and 3.48 times, respectively). Chittagong and Dhaka had about two times odds of child marriage than Sylhet (1.98 and 2.67 times, respectively), even after controlling for selected socio-demographic, economic and cultural characteristics. Respondent's education, employment status, husband's education and wealth index were inversely associated with the prevalence of child marriage. The policy implications of these findings are discussed in the context of Bangladesh.

    Over one-quarter of deaths among 1-4 year-olds in Bangladesh were due to drowning in 2003, and the proportion increased to 42% in 2011. This study describes the current burden and risk factors for drowning across all demographics in rural Bangladesh. A household survey was carried out in 51 union parishads of rural Bangladesh between June and November 2013, covering 1.17 million individuals. Information on fatal and nonfatal drowning events was collected by face-to-face interviews using a structured questionnaire. Fatal and non-fatal drowning rates were 15.8/100,000/year and 318.4/100,000/6 months, respectively, for all age groups. The highest rates of fatal (121.5/100,000/year) and non-fatal (3057.7/100,000/6 months) drowning were observed among children 1 to 4 years of age. These children had higher rates of fatal (13 times) and non-fatal drowning (16 times) compared with infants. Males had slightly higher rates of both fatal and non-fatal drowning. Individuals with no education had 3 times higher rates of non-fatal drowning compared with those with high school or higher education. Non-fatal drowning rates increased significantly with decrease in socio-economic status (SES) quintiles, from the highest to the lowest. Drowning is a major public health issue in Bangladesh, and is now a major threat to child survival.

    2014-05-01

    Full Text Available The spatial pattern and epidemiology of backyard pig farming and other low bio-security pig production systems and their role in the occurrence of classical swine fever (CSF is described and evaluated. A spatial Bayesian model was used to explore the risk factors, including human demographics, socioeconomic and environmental factors. The analyses were performed for Bulgaria, which has a large number of backyard farms (96% of all pig farms in the country are classified as backyard farms, and it is one of the countries for which both backyard pig and farm counts were available. Results reveal that the high-risk areas are typically concentrated in areas with small family farms, high numbers of outgoing pig shipments and low levels of personal consumption (i.e. economically deprived areas. Identification of risk factors and high-risk areas for CSF will allow to targeting risk-based surveillance strategies leading to prevention, control and, ultimately, elimination of the disease in Bulgaria and other countries with similar socio-epidemiological conditions.

    2011-01-01

    This paper investigates the state-sponsored low cost housing provided to previously disadvantaged communities in the City of Cape Town. The strain imposed on municipal services by informal densification of unofficial backyard shacks was found to create unintended public health risks. Four subsidized low-cost housing communities were selected within the City of Cape Town in this cross-sectional survey. Data was obtained from 1080 persons with a response rate of 100%. Illegal electrical connections to backyard shacks that are made of flimsy materials posed increased fire risks. A high proportion of main house owners did not pay for water but sold water to backyard dwellers. The design of state-subsidised houses and the unplanned housing in the backyard added enormous pressure on the existing municipal infrastructure and the environment. Municipal water and sewerage systems and solid waste disposal cannot cope with the increased population density and poor sanitation behaviour of the inhabitants of these settlements. The low-cost housing program in South Africa requires improved management and prudent policies to cope with the densification of state-funded low-cost housing settlements.

    Blood samples and cloacal swabs from poultry were collected in 107 small chicken flocks and 62 pure-bred poultry flocks to determine their status regarding Newcastle disease virus (NDV) infection. A questionnaire emphasizing potential contacts of poultry with wild birds and management practices associated with NDV infection was completed for each flock. Additionally, 1576 wild bird carcasses of 115 different bird species were collected from hunters and taxidermists. Poultry sera and tissue fluids of wild birds were tested for NDV antibodies using a blocking ELISA. Cloacal swabs were subjected to reverse transcription polymerase chain reaction (RT-PCR) for NDV genome detection. In-herd NDV seroprevalences between 5 and 29% were found in one small chicken flock, as well as in four pure-bred poultry flocks. NDV antibody positive wild birds were found in 10.2% of all wild birds examined. Highest proportions (i.e. 15%) of positive birds per species were found among sparrowhawks, kites, tawny owls, eagle owls, barn owls, cuckoos, swifts, cormorants and grebes. No NDV genome was detected in cloacal swabs. This study suggests that buying eggs or poultry abroad and exchanging poultry within the country were factors, more important than wild birds, to explain the higher NDV seropositivity in pure-bred poultry flocks.

    Enteroaggregative (EAEC) and Shiga-toxin producing Escherichia coli (STEC) are a major cause of diarrhea worldwide. E. coli carrying both virulence factors characteristic for EAEC and STEC and producing extended-spectrum beta-lactamase caused severe and protracted disease during an outbreak of E. coli O104:H4 in Europe in 2011. We assessed the opportunities for E. coli carrying the aggR and stx genes to emerge in 'backyard' farms in south-east Asia. Faecal samples collected from 204 chicken farms; 204 farmers and 306 age- and gender-matched individuals not exposed to poultry farming were plated on MacConkey agar plates with and without antimicrobials being supplemented. Sweep samples obtained from MacConkey agar plates without supplemented antimicrobials were screened by multiplex PCR for the detection of the stx1, stx2 and aggR genes. One chicken farm sample each (0.5 %) contained the stx1 and the aggR gene. Eleven (2.4 %) human faecal samples contained the stx1 gene, 2 samples (0.4 %) contained stx2 gene, and 31 (6.8 %) contained the aggR gene. From 46 PCR-positive samples, 205 E. coli isolates were tested for the presence of stx1, stx2, aggR, wzx O104 and fliC H4 genes. None of the isolates simultaneously contained the four genetic markers associated with E. coli O104:H4 epidemic strain (aggR, stx2, wzx O104 and fliC H4 ). Of 34 EAEC, 64.7 % were resistant to 3(rd)-generation cephalosporins. These results indicate that in southern Vietnam, the human population is a more likely reservoir of aggR and stx gene carrying E. coli than the chicken population. However, conditions for transmission of isolates and/or genes between human and animal reservoirs resulting in the emergence of highly virulent E. coli strains are still favorable, given the nature of'backyard' farms in Vietnam.

  6. Sustainable production of broiler chicken and laying hen: bibliographical review and proposal of a model for small producers

    2011-05-01

    Full Text Available The peasant production of broiler chicken and laying hens in the world is wide, being the developing countries which most productions of this type arise. 'ese backyard holdings play an important role as they ensure the consumption of protein products and a subsistence economy to poor families. Due to the low number of technical and scientific studies on these extensive systems in the department of Boyacá, this work aimed to establish by general literature review the world, national and regional state of the art in the production of broiler chicken and alternatively laying hen, and as specific objectives, to produce an analysis of the diferent managements and plans and propose a production model that suits the needs of small producers. the results of the world’s state of the art showed that all countries have a variety of peasant farms, but there is a clear path to commercialization of these poultry farming products, renowned for their safety and quality of nutrients. In some municipalities in Boyacá, these farmers have favorable production systems and yields earnings due to the reduced production costs by the introduction of crop products and recyclable materials, and also have no significant environmental impacts, however, health management is poor and animal feeding starts to rely on concentrated foods.

  7. Water, climate change and society in Bangladesh

    Thiele-Eich, Insa; Aßheuer, Tibor; Simmer, Clemens

    2017-04-01

    Due to its location in the extensive Ganges-Brahmaputra-Meghna river delta, Bangladesh faces multiple natural hazards, in particular flooding, droughts and sea-level rise. In addition to climate change, transboundary water sharing issues resulting from dam structures such as Farakka Barrage complicate a prognosis on how the rapidly growing population will be affected in the 21st century. This is particularly important as our previous research suggests that the Greater Dhaka population already experiences a significant increase in mortality during droughts (Thiele-Eich et al., 2015). We attempt to explore the complex interactions between the hydrological system under climate change and anthropogenic impacts due to dams as well as a growing population. Our approach consists of a quantitative assessment of climate change using over fourty years of meteorological data (Bangladesh Meteorological Department) and hydrological data (Bangladesh Water Development Board), and CCSM4 climate model output (NCAR, 1950-2100). In addition to an extensive literature review, we also conducted qualitative interviews with slum dwellers in the megacity Dhaka, the capital of Bangladesh. Results show that significant changes in flood characteristics are expected for the later part of the 21st century, although they are difficult to quantify down to exact numbers due to large uncertainties. These changes take place over longer stretches of time and thus enable the population of Bangladesh to adapt slowly. Resources such as social capital, which is one of the main tools for slum dwellers to be able to cope with flooding can be altered over time, and as such the system can be considered overall stable and resilient. The presented results will also focus on how the riparian and coastal population is impacted by the interplay of natural changes such as sea-level rise and anthropogenic changes such as Farakka Barrage and the associated reduction in dry season flow.

    With the intensification of not-in-my-backyard (NIMBY) responses to both nuclear and chemical waste management and facility siting, we revisit public participation goals, processes, mechanisms and results to evaluate the uses and limits of public participation for achieving legitimate siting decisions. The deepening loss of trust of the American public in most institutions jeopardizes all preemptive nuclear and hazardous waste facility siting decisions, and carefully structured public participation efforts including some form of power sharing offer the best hope of devising legitimate and durable decisions. We review the key factors in the general siting milieu as well as the thickets of public participation-public involvement. Outcomes of six public participation (PP) case studies are presented and analyzed for problems as well as common factors contributing to their success or failure. The uses as well as the limits of PP in complex nuclear and hazardous waste management and siting processes are considered. 38 refs., 1 tab

    Full Text Available Remittance inflows in the economy of Bangladesh are getting larger every passing year, matching with the increasing external demand for its manpower. The ensuing development impacts of remittances, as a means of transfer of wealth, on socioeconomic factors are increasingly viewed with importance. Remittances have helped improve the social and economic indicators like nutrition, living condition and housing, education, health care, poverty reduction, social security, and investment activities of the recipient households. The relative weight of remittances has also increased against most of the macroeconomic variables alongside the contribution to GDP. Moreover, Bangladesh has been able to avoid any serious imbalances in BOP’s current account, although it has persistent merchandize trade deficits. Not only that, the export tradable sector has thus far remained unaffected from the Dutch Disease effects of remittances.

    Farmers raising less than 100 sows represent more than 99% of swine producers in Argentina, although little is known about their sanitary status and productive characteristics in the country. Sanitary and productive information was obtained. Furthermore, samples for serological studies were taken to detect antibodies against Brucella suis (Bs), Aujeszky's disease virus (AV) and influenza virus (IV) in 68 backyard and small producers with less than 100 sows located in the north, central and south regions of Argentina. Antibodies against H1 pandemic were detected in 80% of the farms while 11%, 11.7% and 6.0% of the producers were positive to influenza H3 cluster 2, AV and Bs, respectively. None of the producers was aware of the risk factors concerning the transmission of diseases from pigs to humans. A percentage of 47% of them buy pigs for breeding from other farmers and markets. With regard to biosecurity measures, only 16% of the farms had perimeter fences. The results of this study demonstrate that productive characterization and disease surveys are important to improve productivity and to reduce the risk of disease transmission among animals and humans. The study of sanitary status and risk factors is necessary for better control and eradication of diseases in backyard or small producers. More representative studies at country level should be carried out to detect the pathogensthat circulate and, with this knowledge, to implement prevention and control measures.

    Introduction Information regarding career choices of medical students is important to plan human resources for health, design need-based educational programs, and ensure equitable and quality health care services in a country. Aim The aim of the study is to identify career choices, nature of career, intended practice locations, and reasons for career choices of Bangladesh medical students. Method First-, third-, and fifth-year students of Bangladesh Medical College and Uttara Adhunik Medical College completed a self-report questionnaire on career choices, nature of career, intended practice locations, and reasons for career choices. The students were requested to choose three long-term choices from the given specialties. Results A total of 132 students responded (46 males and 86 females) and response rate was 75%. The popular choices (first choice) among males and females were medical specialty, surgical specialty, obstetrics and gynecology, and general practice. For first, second, and third choices altogether, male students chose surgical specialties and female students preferred medical specialties. The leading reasons for selecting a specialty were personal interest and wide job opportunity. More than 67% of respondents wanted to join private services and about 90% chose major cities as practice locations. About 43% of respondents expressed willingness to practice medicine in Bangladesh, whereas 51% of total respondents wanted to practice abroad. Discussion Majority of students intended to specialize in established clinical specialties and subsequently practice in major cities, and more than half wanted to immigrate to other countries. Basic medical subjects and service-oriented (lifestyle-related) and preventive/social medical specialties were found to be less attractive. If this pattern continues, Bangladesh will suffer a chronic shortage of health personnel in certain specialties and in rural areas. Conclusions Reorientation of health care and medical

    Full Text Available Tourism appeal includes natural places like beaches, eco-parks, lakes, valleys, rivers, islands etc., archeological sites, historic mosques and monuments, resorts, picnic spots, forest and wildlife. Bangladesh is a riverine country having attractive panoramic beauty. There are hills, valley, canals, lake, eco-park and mangrove forests, rivers, so many islands and the longest beach in the world. In this country, the scope of nature based tourism, resource based tourism, culture based tourism and eco-tourism is quite evident. Bangladesh is trying hard to develop its tourism industry. Therefore the whole situation deserves to be seen from right perspectives. Role of government is positive since the last twenty years both private and public organizations have come forwarded to attract the local and foreign tourists. The cracks of problem could not identify accurately because of the paucity number of researches and investigations in our country. Developed and organized tourism industry could change the economic condition and contribute a big share in the GDP of Bangladesh. This study will impede the opportunities of developing tourism industry in the light of existing resources.

    This paper aimed at the analysis of rainfall seasonality and variability for the northern part of South-Asian country, Bangladesh. The coefficient of variability was used to determine the variability of rainfall. While rainfall seasonality index ( SI ) and mean individual seasonality index ( \\overline{SI_i} ) were used to identify seasonal contrast. We also applied Mann-Kendall trend test and sequential Mann-Kendall test to determine the trend in seasonality. The lowest variability was found for monsoon among the four seasons whereas winter has the highest variability. Observed variability has a decreasing tendency from the northwest region towards the northeast region. The mean individual seasonality index (0.815378 to 0.977228) indicates that rainfall in Bangladesh is "markedly seasonal with a long dry season." It was found that the length of the dry period is lower at the northeastern part of northern Bangladesh. Trend analysis results show no significant change in the seasonality of rainfall in this region. Regression analysis of \\overline{SI_i} and SI, and longitude and mean individual seasonality index show a significant linear correlation for this area.

    The Rohingya people are one of the most ill-treated and persecuted refugee groups in the world, having lived in a realm of statelessness for over six generations, and who are still doing so. In recent years, more than 500,000 Rohingyas fled from Myanmar (Burma) to neighboring countries. This article addresses the Rohingya refugee crisis in Bangladesh, with special emphasis on the living conditions of this vulnerable population. We reviewed several documents on Rohingya refugees, visited a registered refugee camp (Teknaf), collected case reports, and conducted a series of meetings with stakeholders in the Cox's Bazar district of Bangladesh. A total of 33,131 registered Rohingya refugees are living in two registered camps in Cox's Bazar, and up to 80,000 additional refugees are housed in nearby makeshift camps. Overall, the living conditions of Rohingya refugees inside the overcrowded camps remain dismal. Mental health is poor, proper hygiene conditions are lacking, malnutrition is endemic, and physical/sexual abuse is high. A concerted diplomatic effort involving Bangladesh and Myanmar, and international mediators such as the Organization of Islamic Countries and the United Nations, is urgently required to effectively address this complex situation.

    Full Text Available As a third world country and a former British colony, Bangladesh has seen a dramatic upsurge in the use of the English language. Built on the concept of imperialistic aspects of the English language, this paper draws on responses from anonymous survey results and interviews and attempts to provide deeper insights into the global aspects of English as a language and the credibility of this language in the minds of the populace. This paper assesses the English language as a feature of globalization where English is considered to be of the utmost value. Questionnaires were designed and interviews were arranged to evaluate the commercial and linguistic aspects of English in Bangladesh to reach a conclusion whether the mass perceives this very language as it should be or there are any other economic and cultural aspects. The findings were presented graphically and the study showed that English fails to meet the expectations of the stakeholders and policy makers of Bangladesh. The paper concludes with some recommendations that could help resolve the situation and present English to the people in a better light.

    2014-07-01

    Full Text Available Aim: Mastitis is recognized as one of the most costly health disorder affecting dairy cows. An epidemiological study was carried out at some selected farms in Chittagong district of Bangladesh to determine the prevalence and risk factors of sub-clinical mastitis (SCM in dairy cows. Materials and Methods: For conducting the study, some dairy farms of Chittagong were selected from urban and periurban areas by stratified random sampling. A total of 444 quarter samples of 111 (56 from commercial dairy farms and 55 from backyards lactating dairy cows were considered. Sub-clinical mastitis (SCM was determined using three different indirect screening tests: California Mastitis Test (CMT, White Slide Test (WST and Surf Field Mastitis Test (SFMT. Sensitivity and specificity were also determined to measure the accuracy of those tests. Results: The prevalence of SCM by CMT, WST and SFMT were 32.43% (n=144, 33.56% (n=149 and 31.53% (n=140, respectively. Distribution of SCM in relation to different variables at quarter level and animal level was also recorded. The prevalence of SCM was significantly (P4 than others at quarter level. No significant difference (P>0.05 was found in relation to breed. Using CMT as a gold standard, sensitivity and specificity of WST and SFMT were also calculated at 95% confidence interval. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, negative predictive value and disease prevalence by WST and SFMT were comparable. Conclusion: This study recommends that regular screening of sub-clinical mastitis will reduce the prevalence of sub-clinical mastitis. The most effective way to control sub-clinical mastitis is to take preventive measures such as regular cleaning of the floor, keeping the udder clean, milkman's cleanliness, dry cow therapy specially in high yielding dairy cows.

  13. Visuospatial selective attention in chickens.

    Voluntary control of attention promotes intelligent, adaptive behaviors by enabling the selective processing of information that is most relevant for making decisions. Despite extensive research on attention in primates, the capacity for selective attention in nonprimate species has never been quantified. Here we demonstrate selective attention in chickens by applying protocols that have been used to characterize visual spatial attention in primates. Chickens were trained to localize and report the vertical position of a target in the presence of task-relevant distracters. A spatial cue, the location of which varied across individual trials, indicated the horizontal, but not vertical, position of the upcoming target. Spatial cueing improved localization performance: accuracy (d') increased and reaction times decreased in a space-specific manner. Distracters severely impaired perceptual performance, and this impairment was greatly reduced by spatial cueing. Signal detection analysis with an "indecision" model demonstrated that spatial cueing significantly increased choice certainty in localizing targets. By contrast, error-aversion certainty (certainty of not making an error) remained essentially constant across cueing protocols, target contrasts, and individuals. The results show that chickens shift spatial attention rapidly and dynamically, following principles of stimulus selection that closely parallel those documented in primates. The findings suggest that the mechanisms that control attention have been conserved through evolution, and establish chickens--a highly visual species that is easily trained and amenable to cutting-edge experimental technologies--as an attractive model for linking behavior to neural mechanisms of selective attention.

    Current priorities for diarrhoeal disease prevention include use of sanitation and safe water. There have been few attempts to quantify the importance of animal faeces in drinking-water contamination, despite the presence of potentially water-borne zoonotic pathogens in animal faeces. This study aimed to quantify the relationship between livestock ownership and point-of-consumption drinking-water contamination. Data from nationally representative household surveys in Nepal, Bangladesh, and Ghana, each with associated water quality assessments, were used. Multinomial regression adjusting for confounders was applied to assess the relationship between livestock ownership and the level of drinking-water contamination with E. coli. Ownership of five or more large livestock (e.g. cattle) was significantly associated with drinking-water contamination in Ghana (RRR=7.9, 95% CI=1.6 to 38.9 for medium levels of contamination with 1-31cfu/100ml; RRR=5.2, 95% CI=1.1-24.5 for high levels of contamination with >31cfu/100ml) and Bangladesh (RRR=2.4, 95% CI=1.3-4.5 for medium levels of contamination; non-significant for high levels of contamination). Ownership of eight or more poultry (chickens, guinea fowl, ducks or turkeys) was associated with drinking-water contamination in Bangladesh (RRR=1.5, 95% CI=1.1-2.0 for medium levels of contamination, non-significant for high levels of contamination). These results suggest that livestock ownership is a significant risk factor for the contamination of drinking-water at the point of consumption. This indicates that addressing human sanitation without consideration of faecal contamination from livestock sources will not be sufficient to prevent drinking-water contamination.

    2013-11-23

    How do we explain the paradox that Bangladesh has made remarkable progress in health and human development, yet its achievements have taken place within a health system that is frequently characterised as weak, in terms of inadequate physical and human infrastructure and logistics, and low performing? We argue that the development of a highly pluralistic health system environment, defined by the participation of a multiplicity of different stakeholders and agents and by ad hoc, diffused forms of management has contributed to these outcomes by creating conditions for rapid change. We use a combination of data from official sources, research studies, case studies of specific innovations, and in-depth knowledge from our own long-term engagement with health sector issues in Bangladesh to lay out a conceptual framework for understanding pluralism and its outcomes. Although we argue that pluralism has had positive effects in terms of stimulating change and innovation, we also note its association with poor health systems governance and regulation, resulting in endemic problems such as overuse and misuse of drugs. Pluralism therefore requires active management that acknowledges and works with its polycentric nature. We identify four key areas where this management is needed: participatory governance, accountability and regulation, information systems, and capacity development. This approach challenges some mainstream frameworks for managing health systems, such as the building blocks approach of the WHO Health Systems Framework. However, as pluralism increasingly defines the nature and the challenge of 21st century health systems, the experience of Bangladesh is relevant to many countries across the world.

    2015-08-01

    In its strategic planning for the "Astronomy for Development Project," the International Astronomical Union (IAU) has ecognized, among other important missions, the role of astronomy in understanding the far-reaching possibilities for promoting global tolerance and citizenship. Furthermore, astronomy is deemed inspirational for careers in science and technology. The "Pilot Astronomy Outreach Project in Bangladesh"--the first of its kind in the country--aspires to fulfill these missions. As Bangladesh lacks resources to promote astronomy education in universities and schools, the role of disseminating astronomy education to the greater community falls on citizen science organizations. One such group, Anushandhitshu Chokro (AChokro) Science Organization, has been carrying out a successful public outreach program since 1975. Among its documented public events, AChokro organized a total solar eclipse campaign in Bangladesh in 2009, at which 15,000 people were assembled in a single open venue for the eclipse observation. The organization has actively pursued astronomy outreach to dispel public misconceptions about astronomical phenomena and to promote science. AChokro is currently working to build an observatory and Science Outreach Center around a recently-acquired 14-inch Scmidt-Cassegrain telescope and a soon-to-be-acquired new 16-inch reflector, all funded by private donations. The telescopes will be fitted with photometers, spectrometers, and digital and CCD cameras to pursue observations that would include sun spot and solar magnetic fields, planetary surfaces, asteroid search, variable stars and supernovae. The Center will be integrated with schools, colleges, and community groups for regular observation and small-scale research. Special educational and observing sessions for adults will also be organized. Updates on the development of the Center, which is expected to be functioning by the end of 2015, will be shared and feedback invited on the fostering of

    This paper deals with Bangladesh's growth rate and the policy implications for its economy. Despite its obvious influence on the economy, population has never been integrated as an endogenous variable in any planning model. Development planning is mostly supported by donor agencies, involving little micro-level planning and practically no trickle-down effect. This paper examines the interaction of population and other development variables in the country's planning process. Much of the rural population consists of landless farmers share croppers, so that the land ownership pattern contributes to low productivity. Population increase is making the rural masses even poorer. This process is further compounded by increasing foreign aid dependence, adverse terms of trade in the international market, low savings and investments, and the rural sector's worsening terms of trade. During 1950-1970 real per capita gross domestic product (GDP) increased only at a rate of 1% per annum and during 1950-1970 real growth of GDP fell behind the population growth rate. A cost benefit analysis of fertility reduction is needed. The cost benefit ratio of most countries varies between 1:10 to 1:30; for Bangladesh it is 1:16. Macro-model studies indicate that the higher the fertility reduction and shorter the period of required decline, the higher will be the benefits in terms of gains in per capita income. There is, however, a contradiction between national and household interests. The latter's decision to have more children has a negative spillover effect, which nullifies the gains of the community. The national family planning program suffered a serious setback during and after the liberation of Bangladesh, mainly due to lack of administrative leadership and support. In order for the population growth rate to be checked and to increase the quality of life for the entire population, the family planning program must be revitalized by mobilizing the entire government machinery and

    Dhaka, the capital of Bangladesh with a population of over 17 million people, is among the top five coastal cities most vulnerable to climate change, with over 30 % of the population living in slums. Effective disaster mitigation and adaptation requires an understanding how hazards such as flooding impact the population. The impacts of climate change on flooding and thus livelihoods in the complex delta of the Ganges-Brahmaputra-Meghna rivers can not be treated isolated from other anthropogenic impacts due to e.g. the construction of dams as well as a growing population. We illustrate this by setting up a conceptual socio-hydrological causal network using the enhanced Driving force - Pressure - State - Impact - Response framework. The constructed socio-hydrological framework includes both natural and anthropogenic processes and their two-way feedbacks, allowing policy makers to know where available resources can be used effectively to increase resilience and reduce vulnerability. We conclude that climate change takes place over long stretches of time and thus enable the population of Bangladesh to adapt slowly. Resources such as social capital, which is one of the main tools for slum dwellers to be able to cope with flooding can be altered over time, and as such the system can be considered overall stable and resilient. However, transboundary water sharing issues during the dry season and other implications resulting from dam structures such as Farakka Barrage complicate a prognosis on how the rapidly growing population will be affected in the 21st century. This is particularly important in connection with previous findings, which suggest that the Greater Dhaka population already experience a significant increase in mortality during droughts. Climate change can thus be seen as an anthropogenic amplification of the socio-hydrological challenges already faced by Bangladesh today.

    2017-01-01

    While studies on fertility and contraceptives issues are available, until recently adolescent motherhood has not received enough attention among policy makers in understanding adolescent motherhood in Bangladesh. We aimed to examine the trends and determinants of adolescent motherhood among women aged 15-49 years. For trend analysis we used all the 7 waves of Bangladesh Demographic and Health Survey (BDHS, 1993-2014) data but for multivariate analysis 4 waves of BDHS (2004-2014). Two separate analyses were carried out on ever married women aged 15-49: (1) teenage girls aged 15-19 and (2) adult women aged 20 and above. The prevalence of adolescent motherhood had declined to a slower pace from 1993 to2014 (from 33.0% to 30.8%). Lower spousal age gap and higher education were found to be associated with lower likelihood of adolescent motherhood both among teenage girls [OR 0.447 (0.374-0.533)] and adult women [OR 0.451 (0.420-0.484)]. Teenage girls in the poorest wealth quintile [OR 1.712 [1.350-2.173] were more likely to experience adolescent motherhood than the richest wealth quintile. Teenage girls who had no education were found to have 2.76 times higher odds of adolescent motherhood than their counterparts who had higher than secondary education. Concerning the time effect, the odds of adolescent motherhood among adult women was found to decline overtime. Despite substantial decrease in total fertility rate in Bangladesh adolescent motherhood is still highly prevalent though declining from 1993 to 2014. Social policies including those addressing poverty, ensuring greater emphasis on education for women; and adolescent mothers in rural areas are needed.

  1. Electrochemical arsenic remediation for rural Bangladesh

    Energy Technology Data Exchange (ETDEWEB)

    2008-01-01

    Arsenic in drinking water is a major public health problem threatening the lives of over 140 million people worldwide. In Bangladesh alone, up to 57 million people drink arsenic-laden water from shallow wells. ElectroChemical Arsenic Remediation(ECAR) overcomes many of the obstacles that plague current technologies and can be used affordably and on a small-scale, allowing for rapid dissemination into Bangladesh to address this arsenic crisis. In this work, ECAR was shown to effectively reduce 550 - 580 μg=L arsenic (including both As[III]and As[V]in a 1:1 ratio) to below the WHO recommended maximum limit of 10 μg=L in synthetic Bangladesh groundwater containing relevant concentrations of competitive ions such as phosphate, silicate, and bicarbonate. Arsenic removal capacity was found to be approximately constant within certain ranges of current density, but was found to change substantially between ranges. In order of decreasing arsenic removal capacity, the pattern was: 0.02 mA=cm2> 0.07 mA=cm2> 0.30 - 1.1 mA=cm2> 5.0 - 100 mA=cm2. Current processing time was found to effect arsenic removal capacity independent of either charge density or current density. Electrode polarization studies showed no passivation of the electrode in the tested range (up to current density 10 mA=cm2) and ruled out oxygen evolution as the cause of decreasing removal capacity with current density. Simple settling and decantation required approximately 3 days to achieve arsenic removal comparable to filtration with a 0.1 mu m membrane. X-ray Absorption Spectroscopy (XAS) showed that (1) there is no significant difference in the arsenic removal mechanism of ECAR during operation at different current densities and (2) the arsenic removal mechanism in ECAR is consistent with arsenate adsorption onto a homogenous Fe(III)oxyhydroxide similar in structure to 2-line ferrihydrite. ECAR effectively reduced high arsenic concentrations (100

    Since 1975 there has been a family planning program operating in Bangladesh which advertises and commercially distributes contraceptive products in both rural and urban areas throughout the country. The program, known as the Social Marketing Project (SMP) and managed by Population Services International (PSI), now serves almost 1 million acceptors per month at an annual cost per couple of less than US$6.50, including the cost of donated contraceptives. This paper looks at the evolution of the project and its growth through the years, and addresses some primary concerns of planners of social marketing programs.

    Bangladesh is a small country covering about 148 thousand square kilometer area with a population of 120 million. It has only 15% urban area; most of the people live in the rural area. It is neither industrial nor developed. It is trying hard to stand on its feet combating all damages caused by frequent natural calamities like cyclones and floods. Thus, most of the technological activities are still being carried out on turnkey basis. However, some research and development institutions have already been developed to such an extent that transfer of technology can occur and the local industries can also benefit out of this endeavour

    2009-03-01

    In this article, I explore the experiences and concerns of Bangladeshi nurses. I have based this on a larger ethnographic study that was conducted in a ward of a government teaching hospital in Bangladesh. The study shows how the values and norms of Bangladeshi society have shaped the life of Bangladeshi nurses, that they do scarcely any nursing work, and that they suffer from various negative social images. I argue, through this article, that the role, image, and concerns of Bangladeshi nurses have changed dramatically from the ideal image of nursing, and are dissimilar from the ways nursing is practiced in many other parts of the world.

    Full Text Available Background: The Cucurbitaceae family comprising about 125 genera and 960 species is a family that is further characterized by commonly having five-angled stems and coiled tendrils and is also known as gourd family of flowering plants. Plant species belonging to this family have a worldwide distribution, but most species can be found in tropical and subtropical countries. A number of the plants belonging to this family have reported important pharmacological activities. Cucurbitaceae family plants are also in use in the folk medicinal system of Bangladesh-a traditional medicinal system, which mainly relies on medicinal plants for treatment of diverse ailments. Aims: Since folk medicinal practitioners form the first tier of primary health care in Bangladesh, the objective of this study was to conduct ethnomedicinal surveys among 75 folk medicinal practitioners (Kavirajes practicing among the mainstream Bengali-speaking population of randomly selected 75 villages in 64 districts of Bangladesh and 8 tribal practitioners (1 each from 8 major indigenous communities or tribes, namely, Bede, Chakma, Garo, Khasia, Marma, Murong, Santal, and Tripura of the country. Materials and Methods: Surveys were carried out with the help of a semi-structured questionnaire and the guided field-walk method. Results: It was observed that the folk and tribal medicinal practitioners use a total of 19 Cucurbitaceae family species for treatment of ailments such as dysentery, diabetes, edema, skin disorders, leukoderma, hypertension, jaundice, typhoid, spleen disorders, respiratory problems, leprosy, rheumatoid arthritis, chicken pox, and cancer. The 19 species of Cucurbitaceae family plants in use were Benincasa hispida, Bryonopsis laciniosa, Citrullus colocynthis, Citrullus lanatu, Coccinia grandis, Cucumis melo, Cucumis sativus, Cucurbita maxima, Cucurbita pepo, Hodgsonia macrocarpa, Lagenaria vulgaris, Luffa acutangula, Luffa cylindrica, Momordica charantia, Momordica

    Full Text Available Biotechnology is the knowledge and techniques of developing and using biological systems for deriving special products and services. The age-old technology took a new turn with the advent of recombinant DNA techniques, and boosted by the development of other molecular biological techniques, cell culture techniques and bioinformatics. Medical biotechnology is the major thrust area of biotechnology. It has brought revolutions in medicine – quick methods for diagnosing diseases, generation of new drugs and vaccines, completely novel approach of treatment are only a few to mention. The industrial and financial bulk of the industry mushroomed very rapidly in the last three decades, led by the USA and western advanced nations. Asian countries like China, India, South Korea, Taiwan and Singapore joined late, but advancing forward in a big way. In all the Asian countries governments supported the initiatives of the expert and entrepreneur community, and invested heavily in its development. Bangladesh has got great potential in developing biotechnology and reaping its fruits. However, lack of commitment and patriotism, and too much corruption and irresponsibility in political and bureaucratic establishment are the major hindrance to the development of biotechnology in Bangladesh.

    Full Text Available Bangladesh is a densely populated country. Only a small part of her area is electrified which cover around 18% of total population. The people who are in the electrified area are suffering from severe load shedding. A systematic load management procedure related to demand side may improve the situation is the research problem. The major objectives serve by the research are to analyze contemporary electricity status with a view to drawing inference about demand supply gap and extracting benefits from load management. Data supplied by the Bangladesh Power Development Board, World Bank and outcome of survey are analyzed with some simple statistical tools to test the hypothesis. Analysis discloses that with properly managed uses of electricity with load switch and rotation week-end can improve the concurrent condition of electricity. Moreover, introducing smart distribution system, reducing system loss, shifting load to off-peak, large scale use of prepaid mete, observing energy week and using energy efficient home and office appliance are recommended to improve load through demand side management. Some other recommendations such as introducing alternative energy, public private partnership and using renewable energy development and producing energy locally are made for load management from the supply side.

  13. Immortalization of chicken preadipocytes by retroviral transduction of chicken TERT and TR.

    Directory of Open Access Journals (Sweden)

    Wei Wang

    Full Text Available The chicken is an important agricultural animal and model for developmental biology, immunology and virology. Excess fat accumulation continues to be a serious problem for the chicken industry. However, chicken adipogenesis and obesity have not been well investigated, because no chicken preadipocyte cell lines have been generated thus far. Here, we successfully generated two immortalized chicken preadipocyte cell lines through transduction of either chicken telomerase reverse transcriptase (chTERT alone or in combination with chicken telomerase RNA (chTR. Both of these cell lines have survived >100 population doublings in vitro, display high telomerase activity and have no sign of replicative senescence. Similar to primary chicken preadipocytes, these two cell lines display a fibroblast-like morphology, retain the capacity to differentiate into adipocytes, and do not display any signs of malignant transformation. Isoenzyme analysis and PCR-based analysis confirmed that these two cell lines are of chicken origin and are free from inter-species contamination. To our knowledge, this is the first report demonstrating the generation of immortal chicken cells by introduction of chTERT and chTR. Our established chicken preadipocyte cell lines show great promise as an in vitro model for the investigation of chicken adipogenesis, lipid metabolism, and obesity and its related diseases, and our results also provide clues for immortalizing other avian cell types.

    1978-01-01

    A double-antibody solid-phase radioimmunoassay for chicken avidin is reported. Avidin was labelled with 125 I by the chloramine-T method. The bound and free avidin were separated with a second antibody bound to a solid matrix. In the logit-log scale the standard curve was linear from 1-2 to 100-200ng of avidin/ml. Cross-reaction of ovalbumin was less than 0.015%. Saturation of biotin-binding sites of avidin with an excess of biotin decreased radioimmunoassay values by about 15%. Recovery studies indicated that avidin can be assayed from all chicken tissues studied with radioimmunoassay, whereas the [ 14 C]biotin/bentonite method gave poor recoveries for avidin in the liver and kidney. Radioimmunoassay and the [ 14 C]biotin/bentonite method gave similar concentrations for oviduct avidin. (author)

    2017-12-01

    The plastic-derived product, nowadays, becomes an indispensable commodity for different purposes. A huge amount of used plastic causes environmental hazards that turn in danger for marine life, reduces the fertility of soil, and contamination of ground water. Management of this enormous plastic waste is challenging in particular for developing countries like Bangladesh. Lack of facilities, infrastructure development, and insufficient budget for waste management are some of the prime causes of improper plastic management in Bangladesh. In this study, the route of plastic waste production and current plastic waste management system in Bangladesh have been reviewed extensively. It emerges that no technical and improved methods are adapted in the plastic management system. A set of the sustainable plastic management system has been proposed along with the challenges that would emerge during the implementation these strategies. Successful execution of the proposed systems would enhance the quality of plastic waste management in Bangladesh and offers enormous energy from waste.

  8. Poverty-led higher population growth in Bangladesh.

    Science.gov (United States)

    Nakibullah, A; Rahman, A

    1996-01-01

    This article discusses the issue whether population growth is exogenous or endogenous in the economic development of Bangladesh. Overpopulation adversely affects food supplies, foreign exchange, and human resources. Moreover, it depresses savings per capita and retards growth of physical capital per labor. Underdeveloped countries, like Bangladesh, are faced with the problem of allocating resources between infrastructure, education, and health service that are essential for human capital development and population control measures. With this, determination whether fertility is exogenous or endogenous is important for policy purposes in the context of Bangladesh. Results showed that there is a correlation between population growth and real gross domestic products per capita. Based on Granger causality test, population growth is endogenous in the development process of Bangladesh and its overpopulation is due to poverty. Thus, there is a need for appropriate policy to take measures to improve human capital and decrease fertility rates.

  9. Understanding arsenic contamination of groundwater in Bangladesh

    International Nuclear Information System (INIS)

    Kabir, Babar

    2001-01-01

    The problem of water contamination by naturally occurring arsenic confronts governments, public and private utilities, and the development community with a new challenge for implementing operational mitigation activities under difficult conditions of imperfect knowledge - especially for arsenic mitigation for the benefit of the rural poor. With more than a conservative estimate of 20 million of its 130 million people assumed to be drinking contaminated water and another 70 million potentially at risk, Bangladesh is facing what has been described as perhaps the largest mass poisoning in history. High concentrations of naturally occurring arsenic have already been found in water from tens of thousands of tube wells, the main source of potable water, in 59 out of Bangladesh's 64 districts. Arsenic contamination is highly irregular, so tube wells in neighboring locations or even different depths can be safe. Arsenic is extremely hazardous if ingested in drinking water or used in cooking in excess of the maximum permissible limit of 0.01 mg/liter over an extended period of time. Even in the early 1970s, most of Bangladesh's rural population got its drinking water from surface ponds and nearly a quarter of a million children died each year from water-borne diseases. Groundwater now constitutes the major source of drinking water in Bangladesh with 95% of the drinking water coming from underground sources. The provision of tube well water for 97 percent of the rural population has been credited with bringing down the high incidence of diarrheal diseases and contributing to a halving of the infant mortality rate. Paradoxically, the same wells that saved so many lives now pose a threat due to the unforeseen hazard of arsenic. The provenance of arsenic rich minerals in sediments of the Bengal basin as a component of geological formations is believed to be from the Himalayan mountain range. Arsenic has been found in different uncropped geological hard rock formations

    2016-12-01

    An important omission in the Southeast Asian observing network is the border region with the Indian subcontinent. Significant amounts of pollution are generated and transported down the Indo-Gangenic Plain into the Bay of Bengal. High population density in a semi-arid region leads to the development of a complex mixture of absorbing pollution coupled with dust. Transport patterns of this mixture takes pollutants into Bangladesh, where more pollution is added to the atmosphere-leading to what is one of the highest non urban emission loading in the world (AOD500= 0.75 during the premonsoon season). Bangladesh is essentially a riverine country, and atmospheric outflow is over delta regions fed by over 500 rivers, including the Ganges, Bramaputra, Jamuna, and Padma systems forming the massive Meghna river. This combination of atmospheric and riverine components makes for an optically complex littoral region which challenges a host of environmental sensors and modeling systems. Data is needed to understand the sources, transport and optical characteristics of aerosol particles in the region. Dhaka (23.8103° N, 90.4125° E) is the capital of Bangladesh with a population of about 16 million. It has been growing rapidly with all the problem of a mega city. We have installed a sun photometer with NASA Aeronet project at the roof of the Chemistry Department, Dhaka University with other aerosol particles and gas measuring instruments. Bhola is an Island of the Bay of Bengal. It is surrounded by the Meghna River on the north and east, the Tatulia River on the west and the Bay of Bengal on the south. The observatory is located at Charfashion Bazar, Bhola (N 22o10´01″, E 90o45´00″, 3m asl). There is very little influence from traffic and industrial emissions. A Cimel sunphotometer (NASA AERONET) was installed for AOD measurements at this locations since 2013. Aerosol optical depth (AOD) trends between 2012 and 2016 at two different locations (Dhaka and Bhola) will be

  18. Coastal surface water suitability analysis for irrigation in Bangladesh

    2018-03-01

    Water with adequate quality and quantity is very important for irrigation to ensure the crop yields. Salinity is common problem in the coastal waters in Bangladesh. The intensity of salinity in the coastal zone in Bangladesh is not same. It fluctuates over the year. Sodium is another hazard which may hamper permeability and ultimately affects the fertility. It can reduce the crop yields. Although surface water is available in the coastal zone of Bangladesh, but its quality for irrigation needs to be monitored over the year. This paper will investigate the overall quality of coastal surface waters. Thirty-three water samples from different rivers were collected both in wet period (October-December) and in dry period (February-April). Different physical and chemical parameters are considered for investigation of the adequacy of water with respect to international irrigation water quality standards and Bangladesh standards. A comparison between the dry and wet period coastal surface water quality in Bangladesh will also be drawn here. The analysis shows that coastal surface water in Bangladesh is overall suitable for irrigation during wet period, while it needs treatment (which will increase the irrigation cost) for using for irrigation during dry period. Adaptation to this situation can improve the scenario. An integrated plan should be taken to increase the water storing capacity in the coastal area to harvest water during wet period.

    Full Text Available In a democratic system it is essential to have a competitive, and a tolerant party system, but Bangladesh has experienced an intolerant and a confrontational party system that has created a deadlock and brought uncertainty to the whole country. Since 1990, except 2014, Bangladesh has witnessed four systematic peaceful free elections, one each--in 1991, 1996, 2001, and 2008. On January 5, 2014, however, a controversial election took place in which major opposition political parties did not participate except the ruling alliance parties. The two dominant parties—the Bangladesh Nationalist Party (BNP and the Awami League (AL—each won two previous free and fair elections, with the BNP winning in1991, and a BNP-led 4-party coalition in 2001, and the AL in 1996, and an AL-led 14 party alliance in 2008. However, from 2014 Bangladesh is heading towards an authoritarian system. All these are happening due to the lack of good governance. This article intends to emphasize that the political culture emanating from the party politics is retarding good governance in Bangladesh. This article argues that the cultural traits developed in the last four decades in various dimensions,, particularly in more recent years, have worked as an “earth-worm” in the fabrics of democracy in Bangladesh preventing ‘good governance’.

  1. Flavour Chemistry of Chicken Meat: A Review

    Directory of Open Access Journals (Sweden)

    Dinesh D. Jayasena

    2013-05-01

    Full Text Available Flavour comprises mainly of taste and aroma and is involved in consumers’ meat-buying behavior and preferences. Chicken meat flavour is supposed to be affected by a number of ante- and post-mortem factors, including breed, diet, post-mortem ageing, method of cooking, etc. Additionally, chicken meat is more susceptible to quality deterioration mainly due to lipid oxidation with resulting off-flavours. Therefore, the intent of this paper is to highlight the mechanisms and chemical compounds responsible for chicken meat flavour and off-flavour development to help producers in producing the most flavourful and consistent product possible. Chicken meat flavour is thermally derived and the Maillard reaction, thermal degradation of lipids, and interaction between these 2 reactions are mainly responsible for the generation of flavour and aroma compounds. The reaction of cysteine and sugar can lead to characteristic meat flavour specially for chicken and pork. Volatile compounds including 2-methyl-3-furanthiol, 2-furfurylthiol, methionol, 2,4,5-trimethyl-thiazole, nonanol, 2-trans-nonenal, and other compounds have been identified as important for the flavour of chicken. However 2-methyl-3-furanthiol is considered as the most vital chemical compound for chicken flavour development. In addition, a large number of heterocyclic compounds are formed when higher temperature and low moisture conditions are used during certain cooking methods of chicken meat such as roasting, grilling, frying or pressure cooking compared to boiled chicken meat. Major volatile compounds responsible for fried chicken are 3,5-dimethyl-1,2,4-trithiolanes, 2,4,6-trimethylperhydro-1,3,5-dithiazines, 3,5-diisobutyl-1,2,4-trithiolane, 3-methyl-5-butyl-1,2,4-trithiolane, 3-methyl-5-pentyl-1,2,4-trithiolane, 2,4-decadienal and trans-4,5-epoxy-trans-2-decenal. Alkylpyrazines were reported in the flavours of fried chicken and roasted chicken but not in chicken broth. The main reason for

    Full Text Available ABSTRACT Chicken meat in two different forms (chicken meat and chicken meat powder were added into white flour and whole wheat blend baguette bread formulations for protein enrichment and finally developing new and healthy snacks. The chicken meat and powder levels were 10% for white flour baguette, and 15% for whole wheat blend. The dried baguette samples were packaged under 100% N2, and physical, chemical, microbiological and sensorial properties were evaluated during 3 months of storage. Protein content of chicken meat powder added samples were found statistically higher than chicken meat added samples. Hardness of the snacks was significantly affected from type of chicken meat, such as values were higher for chicken meat added samples than chicken meat powder added samples. Lipid oxidation of the snacks was determined by TBA analysis, and TBA value for whole wheat mixture snack with 15% of chicken meat was the highest among all during storage.

    Chicken meat in two different forms (chicken meat and chicken meat powder) were added into white flour and whole wheat blend baguette bread formulations for protein enrichment and finally developing new and healthy snacks. The chicken meat and powder levels were 10% for white flour baguette, and 15% for whole wheat blend. The dried baguette samples were packaged under 100% N2, and physical, chemical, microbiological and sensorial properties were evaluated during 3 months of storage. Protein content of chicken meat powder added samples were found statistically higher than chicken meat added samples. Hardness of the snacks was significantly affected from type of chicken meat, such as values were higher for chicken meat added samples than chicken meat powder added samples. Lipid oxidation of the snacks was determined by TBA analysis, and TBA value for whole wheat mixture snack with 15% of chicken meat was the highest among all during storage. The highest overall acceptance score was obtained from white flour snack with 10% chicken meat. There was no coliform bacteria detected during storage and the results of yeast-mold count and aerobic plate count of snacks remained between the quantitative ranges.

    The study was conducted to document farmers' livelihood aspects and agribusiness potentials in wetland areas of Bangladesh. A total of 120 farmers and 24 service providers were interviewed for data collection. Most of the farmers were small farmers having less than 1.0 ha of cultivable land. The differences in productivity of crop farming and poultry rearing between wetland area and main land were statistically significant. Favorable farm environment and proper utilization of agricultural resources were major strength and opportunity. The data may be helpful for formation of agribusiness clusters involving input suppliers, credit/financial organizations and different support service providers for more income, better nutrition and improved livelihood of the wetland people.

    Professor A.Q.M. Badruddoza Chowdhury, Minister for Health and Population Control, says there is much work to be done in Bangladesh in the field of family planning. Although 67,000 couples had reportedly been sterilized in the previous 6 months, officials claim that the number of acceptors should be an impetus to accelerate the pace of all measures being taken to arrest the population boom. An action program is being formulated by the government to broaden and effectuate the family planning program to contain population to 10 crore (1 crore is 10 million) by the year 2000. The population explosion negates the developments in health, nutrition, education, clothing, housing, communication, and the environment.

    During September 2009, we performed a rapid cross-sectional study to investigate the extent of aflatoxin contamination among common Bangladeshi foods. We collected eight common human food commodities (rice, lentils, wheat flour, dates, betelnut, red chili powder, ginger and groundnuts) and poultry feed samples from two large markets in each of three cities in Bangladesh. We quantified aflatoxin levels from pooled subsamples using fluorescence high-performance liquid chromatography. Aflatoxin levels were highest in dates and groundnuts (maximum 623 and 423 ng/g), respectively. Samples of betelnut (mean 30.6 ng/g), lentils (mean 21.2 ng/g) and red chili powder (>20 ng/g) also had elevated levels. The mean aflatoxin level among poultry feed samples was 73.0 ng/g. Aflatoxin levels were above the US maximum regulatory levels of 20 ng/g in five of eight commonly ingested human food commodities tested.

    Full Text Available Though early diagnosis and intervention of gingivitis in school children can eliminate progression to frank periodontal diseases, no such measures in Bangladesh are in place to detect gingivitis at an early stage in school children. This survey was conducted in 2007 in the primary schools of rural, suburban and urban areas of Bangladesh to evaluate oral hygiene with special emphasis on gingivitis prevalent among 6-13 years school children. The clinical examination of the gingiva was carried out using a mouth mirror and a periodontal probe. A total of 1,820 primary school students (m/f = 946/873 took part in the investigation. The crude prevalence of gingivitis, AS* and plaque were 17.5%, 9.2% and 56.0% respectively. The prevalence of gingivitis was significantly higher in males than females (20.3 vs. 14.3%, p<0.001, lower than upper social class (21.1 vs. 12.6%, p<0.001 and in rural than urban plus suburban children (22.5 vs. 15.1%, p<0.001. Likewise, the prevalence of AS was higher in females, lower social class and rural children. Significantly lower prevalence of gingivitis, AS and plaque was found among those who used tooth brush and tooth paste than those who did not (15.4% vs 22.4%, p<0.001. The study concludes that the prevalence of oro-dental diseases is high in Bangladeshi children. The male children of low social class of rural communities are the most vulnerable group. Ibrahim Med.

    Insulin receptors are present in chicken skeletal muscle. Crude membrane preparations demonstrated specific 125 I-insulin binding. The nonspecific binding was high (36-55% of total binding) and slightly lower affinity receptors were found than are typically observed for crude membrane insulin binding in other chicken tissues. Affinity crosslinking of 125 I-insulin to crude membranes revealed insulin receptor alpha-subunits of Mr 128K, intermediate between those of liver (134K) and brain (124K). When solubilized and partially purified on wheat germ agglutinin (WGA) affinity columns, chicken muscle insulin receptors exhibited typical high affinity binding, with approximately 10(-10) M unlabeled insulin producing 50% inhibition of the specific 125 I-insulin binding. WGA purified chicken muscle insulin receptors also exhibited insulin-stimulated autophosphorylation of the beta-subunit, which appeared as phosphorylated bands of 92- and 81K. Both bands were immunoprecipitated by anti-receptor antiserum (B10). WGA purified membranes also demonstrated dose-dependent insulin-stimulated phosphorylation of the exogenous substrate poly(Glu,Tyr)4:1. However, unlike chicken liver, chicken muscle insulin receptor number and tyrosine kinase activity were unaltered by 48 hr of fasting or 48 hr of fasting and 24 hr of refeeding. Thus, despite the presence of insulin receptors in chicken muscle showing normal coupling to receptor tyrosine kinase activity, nutritional alterations modulate these parameters in a tissue-specific manner in chickens

    2013-07-26

    The study presented here is one of the very first aimed at exploring the potential spread of classical swine fever (CSF) from backyard pigs to other domestic pigs. Specifically, we used a spatial stochastic spread model, called Be-FAST, to evaluate the potential spread of CSF virus (CSFV) in Bulgaria, which holds a large number of backyards (96% of the total number of pig farms) and is one of the very few countries for which backyard pigs and farm counts are available. The model revealed that, despite backyard pigs being very likely to become infected, infections from backyard pigs to other domestic pigs were rare. In general, the magnitude and duration of the CSF simulated epidemics were small, with a median [95% PI] number of infected farms per epidemic of 1 [1,4] and a median [95% PI] duration of the epidemic of 44 [17,101] days. CSFV transmission occurs primarily (81.16%) due to indirect contacts (i.e. vehicles, people and local spread) whereas detection of infected premises was mainly (69%) associated with the observation of clinical signs on farm rather than with implementation of tracing or zoning. Methods and results of this study may support the implementation of risk-based strategies more cost-effectively to prevent, control and, ultimately, eradicate CSF from Bulgaria. The model may also be easily adapted to other countries in which the backyard system is predominant. It can also be used to simulate other similar diseases such as African swine fever.

    The genus Salmonella has more than 2,600 serovars, and this trait is important when considering interventions for Salmonella control. Bacteriophages that are used for biocontrol must have an exclusively lytic cycle and the ability to lyse several Salmonella serovars under a wide range of environmental conditions. Salmonella phages were isolated and characterized from 34 backyard production systems (BPSs) with a history of Salmonella infections. BPSs were visited once, and cloacal or fecal samples were processed for phage isolation. Four hosts, Salmonella serovars Enteritidis, Heidelberg, Infantis, and Typhimurium, were used for phage isolation. The host range of the phages was later characterized with a panel of 23 Salmonella serovars (serovar diversity set) and 31 isolates obtained from the same farms (native set). Genetic relatedness for 10 phages with a wide host range was characterized by restriction fragment length polymorphism, and phages clustered based on the host range. We purified 63 phages, and 36 phage isolates were obtained on Salmonella Enteritidis, 16 on Salmonella Heidelberg, and 11 on Salmonella Infantis. Phages were classified in three clusters: (i) phages with a wide host range (cluster I), (ii) phages that lysed the most susceptible Salmonella serovars (serogroup D) and other isolates (cluster II), and (iii) phages that lysed only isolates of serogroup D (cluster III). The most susceptible Salmonella serovars were Enteritidis, Javiana, and Dublin. Seven of 34 farms yielded phages with a wide host range, and these phages had low levels of genetic relatedness. Our study showed an adaptation of the phages in the sampled BPSs to serogroup D Salmonella isolates and indicated that isolation of Salmonella phages with wide host range differs by farm. A better understanding of the factors driving the Salmonella phage host range could be useful when designing risk-based sampling strategies to obtain phages with a wide lytic host range for biocontrol

    A practical class using clicker training of chickens to apply knowledge of how animals learn and practice skills in animal training was added to an undergraduate course. Since attitudes to animals are related to their perceived intelligence, surveys of student attitudes were completed pre- and post- the practical class, to determine if (1) the practical class changed students' attitudes to chickens and their ability to experience affective states, and (2) any changes were related to previous contact with chickens, training experience or gender. In the post- versus pre-surveys, students agreed more that chickens are easy to teach tricks to, are intelligent, and have individual personalities and disagreed more that they are difficult to train and are slow learners. Following the class, they were more likely to believe chickens experience boredom, frustration and happiness. Females rated the intelligence and ability to experience affective states in chickens more highly than males, although there were shifts in attitude in both genders. This study demonstrated shifts in attitudes following a practical class teaching clicker training in chickens. Similar practical classes may provide an effective method of teaching animal training skills and promoting more positive attitudes to animals.

    Full Text Available Attenuated Salmonella has been used as a carrier for DNA vaccine. However, in vitro and in vivo studies on the bacteria following transfection of plasmid DNA were poorly studied. In this paper, eukaryotic expression plasmids encoding avian influenza virus (AIV subtype H5N1 genes, pcDNA3.1/HA, NA, and NP, were transfected into an attenuated Salmonella enteric typhimurium SV4089. In vitro stability of the transfected plasmids into Salmonella were over 90% after 100 generations. The attenuated Salmonella were able to invade MCF-7 (1.2% and MCF-10A (0.5% human breast cancer cells. Newly hatched specific-pathogen-free (SPF chicks were inoculated once by oral gavage with 109 colony-forming unit (CFU of the attenuated Salmonella. No abnormal clinical signs or deaths were recorded after inoculation. Viable bacteria were detected 3 days after inoculation by plating from spleen, liver, and cecum. Fluorescent in situ hybridization (FISH and polymerase chain reaction (PCR were carried out for confirmation. Salmonella was not detected in blood cultures although serum antibody immune responses to Salmonella O antiserum group D1 factor 1, 9, and 12 antigens were observed in all the inoculated chickens after 7 days up to 35 days. Our results showed that live attenuated S. typhimurium SV4089 harboring pcDNA3.1/HA, NA, and NP may provide a unique alternative as a carrier for DNA oral vaccine in chickens.

    Full Text Available Campylobacter jejuni is responsible for about 90% of cases of Campylobacteriosis in humans with gastroenteritis. Healthy chickens can carry Campylobacter spp. in the intestinal tract. Efforts to reduce exposure to Campylobacteriosis by humans may be enhanced by knowledge of its prevalence in poultry. This study aimed to identify factors associated with seropositive response to C. jejuni in native chickens in Mataram. Detection of C. jejuni was accomplished using an immunochromatographic serological method. Association between Campylobacter jejuni seropositive response as the dependent variable with various independent variables was analyzed using χ² (Chi square and Odds Ratio (OR. A total of 216 chicken samples were examined and 44 chicken owners were interviewed and their farms examined. Results showed the prevalence of serological response to C. jejuni in chicken samples to be as high as 35.6% and that as many as 70.5% of farms had affected chickens. Age of the chicken was the variable most closely associated with incidence of seropositive response, birds older than 3 months more likely to be affected. Variables at the farm level associated with variation in seropositive response were cage type, cage floor material, and origin of drinking water, surface water sources being less desirable.

    A number of individual risk factors for intimate partner violence (IPV) have been identified in Bangladesh. However, the etiology of IPV, intergenerational transmission, has never been tested in Bangladesh. We examined whether witnessing inter-parental physical violence (IPPV) was associated with IPV to identify whether IPV passes across generations in Bangladesh. We used nationally representative data of currently married women from the Bangladesh Demographic and Health Survey-2007. Variations in experiencing IPV were assessed by Chi-square tests. Logistic regression models were fit to determine the association between witnessing IPPV and different types of IPV against women. One-fourth of women witnessed IPPV and experienced IPV. After adjusting for the covariates, women who witnessed IPPV were 2.4 (95% confidence interval [CI]: 2.0-2.8) times more likely to experience any kind of IPV, 2.5 (95% CI: 2.0-3.0) times more likely to experience moderate physical IPV, 2.3 (95% CI: 1.8-3.0) times more likely to experience severe physical IPV, and 1.8 (95% CI: 1.4-2.3) times more likely to experience sexual IPV. Age, age at first marriage, literacy, work status, wealth, justified wife beating, and women's autonomy were also identified as significant correlates of IPV. This study's results indicate that IPV passes from one generation to another. We make recommendations for preventing IPPV so that subsequent generations can enjoy healthy, respectful, nonviolent relationships in married life without exposure to IPV in Bangladesh.

    Although Guillain-Barré syndrome (GBS) has higher incidence and poor outcome in Bangladesh, mortality from GBS in Bangladesh has never been explored before. We sought to explore the frequency, timing, and risk factors for deaths from GBS in Bangladesh. We conducted a prospective study on 407 GBS patients who were admitted to Dhaka Medical College Hospital, Dhaka, Bangladesh from 2010 to 2013. We compared deceased and alive patients to identify risk factors. Cox regression model was used to adjust for confounders. Of the 407 GBS patients, 50 (12%) died, with the median time interval between the onset of weakness and death of 18 days. Among the fatal cases, 24 (48%) were ≥40 years, 36 (72%) had a Medical Research Council sum score ≤20 at entry, 33 (66%) had a progressive phase 8 days) (HR: 2.06; 95% CI: 1.1-3.8), autonomic dysfunction (HR: 1.9; 95% CI: 1.05-3.6), and bulbar nerve involvement (HR: 5.4; 95% CI: 1.5-19.2). In Bangladesh, GBS is associated with higher mortality rates, which is related to lack of ventilator support, disease severity, longer progressive phase of the disease, autonomic dysfunction, and involvement of the bulbar nerves. © 2017 Peripheral Nerve Society.

    Nowadays Bangladesh is facing the problem with electricity as the production is less comparing to the demand. A significant amount of electricity is consumed in urban areas especially by industries whereas in rural or coastal areas most of the people are not having it. Around 40 millions of people living in the 724 km long coast in Bangladesh. Moreover, it is surprising that throughout the year there is sufficient wind blow in coastal areas by which we can produce a massive amount of electricity. However, day by day the utilization of wind energy is increasing in the world which reduces costs of renewable energy technology, improves efficiency. It would be a good alternative solution instead of dependency on natural gas. Wind energy is mainly potential in coastal and offshore areas with strong wind regimes. Wind energy is vital for ensuring a green energy for the future. The agricultural land of Bangladesh needs the supply of water at right time for better yielding. The installation of windmills will be very much convenient for operating the water supply pumps. This research highlights the possibility of wind energy and describes the necessary steps to implement and develop wind energy sector in Bangladesh by using other's successful ideas. Supportive policies, rules, and decree can be applied to make government, non-government organization, and donor organizations work together to develop wind energy sector in Bangladesh.

    Natural gas is the major indigenous source of energy in Bangladesh and accounts for almost one-half of all primary energy used in the country. Per capita and total energy use in Bangladesh is still very small, and it is important to understand how energy, and natural gas demand will evolve in the future. We develop a dynamic econometric model to understand the natural gas demand in Bangladesh, both in the national level, and also for a few sub-sectors. Our demand model shows large long run income elasticity - around 1.5 - for aggregate demand for natural gas. Forecasts into the future also show a larger demand in the future than predicted by various national and multilateral organizations. Even then, it is possible that our forecasts could still be at the lower end of the future energy demand. Price response was statistically not different from zero, indicating that prices are possibly too low and that there is a large suppressed demand for natural gas in the country. - Highlights: → Natural gas demand is modeled using dynamic econometric methods, first of its kind in Bangladesh. → Income elasticity for aggregate natural gas demand in Bangladesh is large-around 1.5. → Demand is price insensitive, indicating too low prices and/or presence of large suppressed demand. → Demand forecasts reveal large divergence from previous estimates, which is important for planning. → Attempts to model demand for end-use sectors were successful only for the industrial sector.

    Bangladesh is one of the smaller states in Asia. But it has a long and rich history of nuclear medicine for over sixty years. The progress in science and technology is always challenging in a developing country. In 1958, work for the first Nuclear Medicine facility was commenced in Dhaka in a tin-shed known as ‘Radioisotope Centre’ and was officially inaugurated in 1962. Since the late 50s of the last century nuclear medicine in Bangladesh has significantly progressed through the years in its course of development, but still the facilities are inadequate. At present there are 20 nuclear medicine establishments with 3 PET-CTs, 42 gamma camera/SPECTs with 95 physicians, 20 physicists, 10 radiochemists and 150 technologists.

    Bangladesh is one of the smaller states in Asia. But it has a long and rich history of nuclear medicine for over sixty years. The progress in science and technology is always challenging in a developing country. In 1958, work for the first Nuclear Medicine facility was commenced in Dhaka in a tin-shed known as 'Radioisotope Centre' and was officially inaugurated in 1962. Since the late 50s of the last century nuclear medicine in Bangladesh has significantly progressed through the years in its course of development, but still the facilities are inadequate. At present there are 20 nuclear medicine establishments with 3 PET-CTs, 42 gamma camera/SPECTs with 95 physicians, 20 physicists, 10 radiochemists and 150 technologists. The Society of Nuclear Medicine, Bangladesh (SNMB) was formed in 1993 and publishing its official journal since 1997. Bangladesh also has close relationships with many international organizations like IAEA, ARCCNM, AOFNMB, ASNM, WFNMB and WARMTH.

    Full Text Available Model system chicken emulsions were prepared by replacing 5, 10, 15 and 20 % beef fat with chicken skin. Moisture, protein, fat, ash and pH were determined in raw and heat processed emulsions. Emulsion samples were evaluated for cooking characteristics, TBA values and colour parameters (L*, a*, b*. Addition of chicken skin decreased fat content and increased moisture and protein content of emulsion samples. Chicken skin replacement significantly increased water holding capacity and cooking yield and decreased fluid release. Increasing chicken skin in formulation increased a* and b* values of emulsion samples. Therefore, adding of chicken skin instead of beef fat is useful in improving technological quality and producing low fat formulation.

    Day-old, straight-run broiler chickens were procured from a hatchery located in the Pacific Northwest. The chickens were subdivided individually into nine groups of 20 chickens. The chickens were tagged, housed in isolation chambers on wire, fed commercial broiler feed, and given water ad libitum. Three isolates of Campylobacter jejuni of poultry origin and one of human origin were tested in this study. Various C. jejuni cultures were inoculated into 9-day-old chickens by crop gavage. Four groups of 20 chickens were inoculated at a dose level of 0.5 ml of 1 x 10(2) colony-forming units (CFU)/ml. The other four groups were inoculated with 0.5 ml of 1 X 10(4) CFU/ml. One group of 20 chickens was kept as an uninoculated control group. Four randomly selected chickens from each of the inoculated and uninoculated groups were necropsied at 5, 12, and 19 days postinoculation (DPI). The C. jejuni was cultured and enumerated from a composite of the upper and midintestine and the cecum. Body weights of all chicken groups at 7 days of age and at 5, 12, and 19 DPI were measured and statistically analyzed. No significant differences were present in the mean body weights (MBWs) of 7-day-old, 5 DPI, and 12 DPI male and female broiler chickens inoculated with C. jejuni at both dose levels compared with uninoculated controls. Differences in MBWs of the male and female broilers at 19 DPI were observed in some of the groups. Results of the C. jejuni culture enumeration mean (CEM) of composite intestine samples at 5 DPI from all inoculated chicken groups, irrespective of the dose level, ranged from (2.5 +/- 5.0) x 10(2) to (2.8 +/- 4.8) x 10(5) CFU/g (mean +/- SD). Results of cecum C. jejuni CEM at 5 DPI inoculated at both dose levels ranged from (2.5 +/- 5.0) x 10(6) to (1 +/- 0.0) x 10(7) CFU/g in all treatment groups irrespective of the dose level. CEM results from the composite intestine samples at 12 and 19 DPI increased by 1 log unit, or sometimes more. Results of cecum C. jejuni

    2015-12-01

    This paper estimates location-specific soil salinity in coastal Bangladesh for 2050. The analysis was conducted in two stages: First, changes in soil salinity for the period 2001-2009 were assessed using information recorded at 41 soil monitoring stations by the Soil Research Development Institute. Using these data, a spatial econometric model was estimated linking soil salinity with the salinity of nearby rivers, land elevation, temperature, and rainfall. Second, future soil salinity for 69 coastal sub-districts was projected from climate-induced changes in river salinity and projections of rainfall and temperature based on time trends for 20 Bangladesh Meteorological Department weather stations in the coastal region. The findings indicate that climate change poses a major soil salinization risk in coastal Bangladesh. Across 41 monitoring stations, the annual median projected change in soil salinity is 39 % by 2050. Above the median, 25 % of all stations have projected changes of 51 % or higher.

    Full Text Available Teaching pronunciation is one the most challenging parts of ELT in Bangladesh. Very few research and least attention on pronunciation teaching has instigated those challenges more. Moreover, setting an ambitious target to achieve native like pronunciation and teaching without considering the Bangladeshi context are more specific reasons for creating those problems. Therefore, this paper concentrates on the discussion of the existing condition of teaching pronunciation in Bangladesh. Consequently, it starts with presenting existing circumstances of pronunciation teaching in Bangladesh, and showing what the achievable and realistic goal should be for this situation. Then, it talks about the challenges that the teachers face while teaching pronunciation in ELT classroom. This discussion provides deep insight into those challenges which are only applicable to Bangladeshi students. Finally, the paper suggests some contextual and practical solutions to those specific problems.

  3. Sustainable agriculture: a challenge in Bangladesh

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The sustainability of conventional agriculture in Bangladesh is under threat from the continuous degradation of land and water resources, and from declining yields due to indiscriminate use of agro-chemicals. Government is pursuing efforts to promote sustainable agriculture with emphasis on better use of on-farm resources and the reduction of external inputs. This paper presents four dimensions of agricultural sustainability as productivity, environmental stability, economical profitability, and social and economic equity. Six characters were selected to evaluate sustainability. Significant differences were found between the two systems (conventional and sustainable agriculture in crop diversification, soil fertility management, pests and diseases management, use of agro-chemicals and environmental issues. However, no significant variations were found in other indicators such as land-use pattern, crop yield and stability, risk and uncertainties, and food security. Although crop yield and financial return were found to be slightly higher in the conventional system, the economic return and value addition per unit of land did not show any difference. It can be suggested that sustainable agriculture has a tendency towards becoming environmental, economically and socially more sound than conventional agriculture, as it requires considerably less agro-chemicals, adds more organic matter to the soil, provides balanced food, and requires higher local inputs without markedly compromising output and financial benefits. Broad-policy measures, including the creation of mass awareness of adverse health effects of agrochemical-based products, are outlined for the promotion of sustainable agriculture.

  4. Coalbed Methane prospect of Jamalganj Coalfield Bangladesh

    Imam, M. Badrul; Rahman, M.; Akhtar, Syed Humayun

    2002-01-01

    Five major Gondwana coalfields have been discovered in the half-graben type basins in the subsurface in the Precambrian platform area of the Northwest Bangladesh. The Jamalganj coalfields with an estimated reserve of about 1053 millions tons of coal, has seven coal seams in the depth range between 640 to 1158m below the ground surface. Compared to the other coalfields of the area, with coal occurring at 150 to 500m depth, Jamalganj coal is considered to be too deep to be exploited by conventional underground or open pit mining. Instead, developing coal bed methane from Jamalganj coalfield may be considered as a viable option for its exploitation. The positive factors of Jamalganj coal bed methane development include high net thickness of coal with at least one very thick (40m+) and widely developed seam, coal seam burial depth within optimum range, large coal reserves, indication of significant gas content from drilling data, and poor permeability in the rocks above and surrounding the coal layers. The thickest seam III can be primary target for CBM development especially where it combines with seam IV in the eastern part of coalfield. However, there are a number of unknown factors like actual gas content of coal, permeability, and in-seam pressure that need to be evaluated before deciding the viability of the project. An initial attempt to collect these base line data should include drilling test well or wells in the primary target area where seam III is most thick and widely developed. (author)

    The applications of radioisotopes and radiation sources to the research and development in medicine, food agriculture, industries and others are rapidly increasing in Bangladesh. The existing major nuclear facilites and allied laboratories of the country include 3 MW TRIGA Mark-2 research reactor for training, research and radioisotope production, 14 MeV neutron generator for nuclear data measurement and elemental analysis via neutron activation, 3 MeV Van de Graaff accelerator for the research and application of nuclear physics, and 50,000 Ci and 5,000 Ci Co-60 irradiators. About 10 Co-60 and Cs-137 teletherapy units are in operation in hospitals. The radioactive contamination of working areas, equipment, protective clothing and skin may result from normal operation and accidents, and contamination monitoring and decontamination are the essential part of radiation protection program. Surface contamination is monitored with Berthold survey meters. Hand and foot monitors have been used. Routine systematic search, continuous air monitoring, the examination of silt movement in Chittagong harbor using Sc-46 tracer and the measurement of tritium contamination for the neutron generator are reported.

    This article explored the magnitude and nature of within marriage sexual violence against women and factors associated with physically forced sex by husbands in urban and rural Bangladesh using population-based survey data from 2001 (n = 2,702). Results showed high prevalence of lifetime sexual violence: 37 % in urban and 50 % in rural areas. An overwhelming majority of the women reported being sexually abused by husbands more than once. Logistic regression analyses revealed that six out of ten independent variables included in the models were significant. The factors positively associated with physically forced sex by husbands during the last 12 months were: history of physical abuse of husband's mother by his father; level of controlling behavior by husband; and forced or coerced first sex. Women's age (20-24 compared to 15-19) and dowry demand at marriage increased the likelihood of this violence in the rural area. Urban women in the second and third income quartiles were more likely to be exposed to this violence compared to women in the first quartile. Results highlight the need for prevention programs targeting men, which would help at the same time to break the cycle of intergenerational exposure and thereby transmission of violence. Notions of gender equality; women's sexual rights; and women's right to consent and choice need to be widely promoted particularly among men.

    Full Text Available In Bangladesh, Formal legal education is provided by either a department of a university or an affiliated college. There are four public universities and above twenty six private universities in our country with law as a regular subject of teaching. Besides, the National University imparts teaching of law through law colleges in the country. All public and private universities providing law graduate degree by conventional system but many people deprived from this opportunities. Thus to increase equitable access to education and to develop the human resources of the country the Bangladesh Open University playing significant role. Large numbers of students of rural areas, particularly women, out of school and adults who must do work to support their families are include with the university. Bangladesh Open University is the only institution in Bangladesh which imparts education in open and distance mode and offers 23 formal programmes, the demand for the introduction of LL.B programme for the benefit of those who have been, for various reasons, deprived of the opportunity of undertaking graduate course in law in conventional mode of education. The decision to offer the programme in distance mode is being taken in response to the earnest desire of the relevant quarters expressed in various dailies and formal applications submitted to the university authority as the learners in the open and distance mode learn at his own place and any time whenever he feels convenient to learn and is not for restricted by time, space or age. Distance learning is, indeed, presently considered as a viable alternative of the conventional system of education to fulfill the growing demand for legal education.This paper presents the new academic trends in Bangladesh Open University by distance learning Bachelor of Laws (LL.B. degree and modern aspects of the legal education at School of Law in Bangladesh Open University.

    Full Text Available The importance of improving trade flows between India and Bangladesh is not only beneficial to them, but for the whole SAARC region, given that Bhutan and Nepal utilise Bangladesh ports as gateways to trade outside the region. Bangladesh’s overall exports are dominated by labour-intensive manufacturing and its imports to India by primary commodities. The shares of manufactured goods in country’s overall export were about 92 and 91 percent in 2001 and 2011 respectively. However, the composition of bilateral trade between these two countries has been changing over time. Addition and removal in the list of products of trade basket is a usual process. Consistent products in the trade basket of Bangladesh are ready made garments and sea food, whereas those of India are raw cotton, cereals and products and machinery of iron and steel. Expansion of trade of these countries with outside world, but not with each other confirms the prevalence of certain barriers, physical or non-physical in nature, rendering many potential products remain untraded. India and Bangladesh being geographically proximate to each other possess huge scope to trade. Specifically as both the countries are rich in natural resources and are competent in the production of small-scale manufacturing and agrarian supplies, mostly from the eastern parts of India and Bangladesh, both possess huge potential for bilateral trade. Many items having high trade potential are still not able to get market exposure in the neighbouring country because of various non-tariff barriers prevailing in current trade scenario, which have hiked up the cost of doing business to unacceptable proportions and as most of the highly tradable products are still kept under the sensitive lists of Bangladesh. There are numerous bottlenecks in the current trade infrastructure which turns out to be physical barrier to trade. The present paper highlights the import export and Exchange Rate change and prospects of

  9. Issues in developing a mitigation strategy for Bangladesh

    1996-12-31

    Bangladesh, it is by now well-known, is at the receiving end, in the literal sense of the term, of the global climate change and its potential impacts. She contributes very little to the current global emission of greenhouse gases (GHGs). The Emission Inventory under the present umbrella project, Bangladesh Climate Change Study (BCCS), has found that her annual emission of carbon has been only 3.99 mn metric tons per year. An earlier study arrived at exactly the same figure. The figures for estimated release of methane is far less firm. The estimated methane emission in 1990 could be anywhere between 1 million and 6 million metric tons. In any case the total emission is unlikely to be more than one-half of one percent of the global total. On the other hand, however, she faces specter of widespread and more frequent floods, more frequent droughts, cyclones and above all sea-level rise (SLR) which may inundate a substantial part of the country all of these bringing in immeasurable misery and destitution and loss of income, employment and growth. One would expect that in such a situation, Bangladesh`s basic concern should be to prepare an appropriate adaptation strategy. This is already a major policy concern of the Government. There is, however, an increasing realization that Bangladesh should as well emphasize an appropriate mitigation strategy (MS). There may be at least three reasons why this should be so. The first is that she is a signatory of the Framework Convention on Climate Change. The second is that in the medium, if not short term she expects major growth due to a developing economy. Third is that Bangladesh depends primarily on fossil fuel imports for energy, and will become a larger source with further development.

    Mortality in ducks and geese caused by highly pathogenic avian influenza A(H5N1) infection had not been previously identified in Bangladesh. In June-July 2011, we investigated mortality in ducks, geese and chickens with suspected H5N1 infection in a north-eastern district of the country to identify the aetiologic agent and extent of the outbreak and identify possible associated human infections. We surveyed households and farms with affected poultry flocks in six villages in Netrokona district and collected cloacal and oropharyngeal swabs from sick birds and tissue samples from dead poultry. We conducted a survey in three of these villages to identify suspected human influenza-like illness cases and collected nasopharyngeal and throat swabs. We tested all swabs by real-time RT-PCR, sequenced cultured viruses, and examined tissue samples by histopathology and immunohistochemistry to detect and characterize influenza virus infection. In the six villages, among the 240 surveyed households and 11 small-scale farms, 61% (1789/2930) of chickens, 47% (4816/10 184) of ducks and 73% (358/493) of geese died within 14 days preceding the investigation. Of 70 sick poultry swabbed, 80% (56/70) had detectable RNA for influenza A/H5, including 89% (49/55) of ducks, 40% (2/5) of geese and 50% (5/10) of chickens. We isolated virus from six of 25 samples; sequence analysis of the hemagglutinin and neuraminidase gene of these six isolates indicated clade 2.3.2.1a of H5N1 virus. Histopathological changes and immunohistochemistry staining of avian influenza viral antigens were recognized in the brain, pancreas and intestines of ducks and chickens. We identified ten human cases showing signs compatible with influenza-like illness; four were positive for influenza A/H3; however, none were positive for influenza A/H5. The recently introduced H5N1 clade 2.3.2.1a virus caused unusually high mortality in ducks and geese. Heightened surveillance in poultry is warranted to guide appropriate

There is as yet no proven treatment available for EVD.1 Raising awareness of risk factors for Ebola infection and protective measures that individuals can take is an effective way to reduce human transmission. Risk reduction messaging should focus on several factors like reducing the risks of wildlife-to-human transmission and human-to-human transmission and also on outbreak containment measures.1 Health care workers caring for patients with suspected or confirmed Ebola virus should apply extra infection control measures to prevent contact with the patient’s blood and body fluids and contaminated surfaces or materials such as clothing and bedding, wear face protection besides routine measures. Samples taken from humans and animals for investigation of Ebola infection should be handled by trained staff with utmost care and processed in suitably equipped laboratories.1 The infections of two health care workers in Dallas, USA and a nurse in Madrid, Spain have revealed the truth that even highly developed nations are not immune. Still, Asia has some advantages as it readies itself for Ebola. Flight patterns suggest that the influx of travelers from Ebola-stricken West African countries to the Asian continent is far less than it is to Africa, Europe or North America.10 The recent outbreak affecting several nations also alarmed the public health sector of Bangladesh. But virus and healthcare experts have assured that there is nothing to be anxious about Ebola in Bangladesh as it has been categorized as among the least threatened countries by the World Health Organization (WHO on August 8, 2014 in its first Emergency Committee meeting.11 Bangladesh Government has already taken effective preventive measures suggested by WHO, which

    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

    Full Text Available A rainfall simulation model based on a first-order Markov chain has been developed to simulate the annual variation in rainfall amount that is observed in Bangladesh. The model has been tested in the Barind Tract of Bangladesh. Few significant differences were found between the actual and simulated seasonal, annual and average monthly. The distribution of number of success is asymptotic normal distribution. When actual and simulated daily rainfall data were used to drive a crop simulation model, there was no significant difference of rice yield response. The results suggest that the rainfall simulation model perform adequately for many applications.

    Full Text Available This study investigates the relationship between remittance and import for the economy of Bangladesh. The study used different econometric techniques of measuring the long and short term relationship between variables. The Johansen Cointegration test is used to determine the existence of a long term relationships between study variables. The normalized Cointegrating coefficients are found statistically significant and show a stable and positive relationship between study variables. Our Granger causality analysis suggests the existence of a unidirectional causality running from import to remittance. This confirms that remittances have no significant impact on the demand for imported goods rather import exerts a positive shock on the remittance of Bangladesh.

    This study analyzed consumers' preferences and price sensitivity to native chickens. A survey was conducted from Jan 6 to 17, 2014, and data were collected from consumers (n=500) living in Korea. Statistical analyses evaluated the consumption patterns of native chickens, preference marketing for native chicken breeds which will be newly developed, and price sensitivity measurement (PSM). Of the subjects who preferred broilers, 24.3% do not purchase native chickens because of the dryness and tough texture, while those who preferred native chickens liked their chewy texture (38.2%). Of the total subjects, 38.2% preferred fried native chickens (38.2%) for processed food, 38.4% preferred direct sales for native chicken distribution, 51.0% preferred native chickens to be slaughtered in specialty stores, and 32.4% wanted easy access to native chickens. Additionally, the price stress range (PSR) was 50 won and the point of marginal cheapness (PMC) and point of marginal expensiveness (PME) were 6,980 won and 12,300 won, respectively. Evaluation of the segmentation market revealed that consumers who prefer broiler to native chicken breeds were more sensitive to the chicken price. To accelerate the consumption of newly developed native chicken meat, it is necessary to develop a texture that each consumer needs, to increase the accessibility of native chickens, and to have diverse menus and recipes as well as reasonable pricing for native chickens.

    Full Text Available Aim: Salmonella is an important zoonotic pathogen responsible for animal and human diseases. The aim of the present study was to determine the prevalence and stereotyping of Salmonella isolates isolated from apparently healthy poultry. Furthermore, the clonal relatedness among the isolated Salmonella serovars was assessed. Materials and Methods: A total of 150 cloacal swab samples from apparently healthy chickens were collected, and were subjected for the isolation and identification of associated Salmonella organisms. The isolated colonies were identified and characterized on the basis of morphology, cultural characters, biochemical tests, slide agglutination test, polymerase chain reaction, and pulsed-field gel electrophoresis (PFGE. Antibiotic sensitivity patterns were also investigated using commonly used antibiotics. Results: Of the 150 samples, 11 (7.33% produced characteristics pink colony with black center on XLD agar medium, and all were culturally and biochemically confirmed to be Salmonella. All possessed serovar-specific gene SpeF and reacted uniformly with group D antisera, suggesting that all of the isolates were Salmonella Enterica serovar Gallinarum, biovar Pullorum and/or Gallinarum. Antimicrobial susceptibility testing revealed that 54.54% of the isolated Salmonella Enterica serovars were highly sensitive to ciprofloxacin, whereas the 81.81% isolates were resistant to amoxycillin, doxycycline, kanamycin, gentamycin, and tetracycline. Pulsed-field gel electrophoresis of the XbaI-digested genomic DNA exhibited identical banding patterns, suggesting that the multidrug resistant Salmonella Enterica serovars occurring in commercial layers are highly clonal in Bangladesh. Conclusion: The present study was conducted to find out the prevalence of poultry Salmonella in layer chicken and to find out the clonal relationship among them. The data in this study suggest the prevalence of Salmonella Enterica, which is multidrug resistant and

    The effects of chicken anemia virus (CAV) and infectious bursal disease virus (IBDV) coinfection in commercial layer-type and meat-type (broiler) chickens with specific maternal immunity were evaluated. In addition, the broiler progeny used had been vaccinated in ovo against IBDV. Layer chickens were inoculated intramuscularly on day 3 of age with CAV and orally on day 7 of age with an IBDV standard strain (APHIS). Broiler chickens were exposed to CAV and/or an IBDV variant strain (AL2) via the drinking water on days 3 and 14 of age. Following CAV and IBDV inoculation neither mortality nor overt clinical disease was observed in any layer or broiler group. In spite of maternal immunity against both IBDV and CAV, mean hematocrits of all layer groups inoculated with CAV (CAV, CAV + APHIS) were lower than uninfected chickens. IBDV APHIS alone or in combination with CAV did not affect the layer weight gain. However, on day 30 of age and concomitantly with maternal antibody decay, bursa lymphocyte depletion became evident in CAV + APHIS-infected layer chickens. These birds (CAV + APHIS) also seroconverted to IBDV on day 35 of age. CAV persisted at low levels in the layer chickens throughout the experimental period in CAV- and CAV+APHIS-infected chickens. Similarly, infected broiler chickens did not show changes in weight gain. Compared to CAV-infected or uninfected controls, CAV+AL2- and AL2-infected broiler chickens showed significant lymphocyte depletion in the bursa as assessed both by bursal indices and histomorphometry. Broilers also seroconverted to IBDV after day 30 of age confirming that bursal lymphocyte depletion was due to IBDV resuming replication. Thymus histomorphometry revealed significant lymphocyte depletion in all infected broiler groups at 30 days of age, but only in CAV+AL2-infected broiler chickens at 41 days of age, suggesting that IBDV infection delayed repopulation of the thymus.

    Avians have the unique ability to regenerate cochlear hair cells that are lost due to ototoxins or excessive noise. Many methodological techniques are available to damage the hair cells for subsequent scientific study. A recent method utilizes topical application of an ototoxic drug to the round window membrane. The current study examines the pharmacokinetics of gentamicin in the inner ear of chickens following topical application to the round window membrane or a single systemic high dose given intraperitoneally. Chickens were given gentamicin topically or systemically and survived for 1, 4, 12, 24, or 120 h (controls at 4 and 120 h). Serum and perilymph samples were obtained prior to sacrifice and measured for gentamicin levels. Results revealed higher levels of gentamicin in the perilymph of topically treated chickens than systemically treated chickens, with significant amounts of gentamicin still present in both at the latest survival time of 5 days. As expected, systemically treated chickens had much higher levels of gentamicin in the serum than topically treated chickens. Advantages and disadvantages to each method of drug administration are discussed.

    The advantages of chicken (Gallus gallus domesticus) antibodies as immunodiagnostic and immunotherapeutic biomolecules has only been recently recognized. Even so, chicken antibodies remain less-well characterized than their mammalian counterparts. This review aims at providing a current overview of the structure, function, development and generation of chicken antibodies. Additionally, brief but comprehensive insights into current knowledge pertaining to the immunogenetic framework and diversity-generation of the chicken immunoglobulin repertoire which have contributed to the establishment of recombinant chicken mAb-generating methods are discussed. Focus is provided on the current methods used to generate antibodies from chickens with added emphasis on the generation of recombinant chicken mAbs and its derivative formats. The advantages and limitations of established protocols for the generation of chicken mAbs are highlighted. The various applications of recombinant chicken mAbs and its derivative formats in immunodiagnostics and immunotherapy are further detailed. Copyright © 2017 Elsevier B.V. All rights reserved.

  7. Microbiological Safety of Chicken Litter or Chicken Litter-Based Organic Fertilizers: A Review

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Chicken litter or chicken litter-based organic fertilizers are usually recycled into the soil to improve the structure and fertility of agricultural land. As an important source of nutrients for crop production, chicken litter may also contain a variety of human pathogens that can threaten humans who consume the contaminated food or water. Composting can inactivate pathogens while creating a soil amendment beneficial for application to arable agricultural land. Some foodborne pathogens may have the potential to survive for long periods of time in raw chicken litter or its composted products after land application, and a small population of pathogenic cells may even regrow to high levels when the conditions are favorable for growth. Thermal processing is a good choice for inactivating pathogens in chicken litter or chicken litter-based organic fertilizers prior to land application. However, some populations may become acclimatized to a hostile environment during build-up or composting and develop heat resistance through cross-protection during subsequent high temperature treatment. Therefore, this paper reviews currently available information on the microbiological safety of chicken litter or chicken litter-based organic fertilizers, and discusses about further research on developing novel and effective disinfection techniques, including physical, chemical, and biological treatments, as an alternative to current methods.

    This study examines the trends and determinants of child marriage among women aged 20-49 in Bangladesh. Data were extracted from the last six nationally representative Demographic and Health Surveys conducted during 1993-2011. Simple cross-tabulation and multivariate binary logistic regression analyses were adopted. According to the survey conducted in 2011, more than 75% of marriages can be categorized as child marriages. This is a decline of 10 percentage points in the prevalence of child marriage compared with the survey conducted in 1993-1994. Despite some improvements in education and other socioeconomic indicators, Bangladeshi society still faces the relentless practice of early marriage. The mean age at first marriage has increased by only 1.4 years over the last one and half decades, from 14.3 years in 1993-1994 to 15.7 years in 2011. Although the situation on risk of child marriage has improved over time, the pace is sluggish. Both the year-of-birth and year-of-marriage cohorts of women suggest that the likelihood of marrying as a child has decreased significantly in recent years. The risk of child marriage was significantly higher when husbands had no formal education or little education, and when the wives were unemployed or unskilled workers. Muslim women living in rural areas have a greater risk of child marriage. Women's education level was the single most significant negative determinant of child marriage. Thus, the variables identified as important determinants of child marriage are: education of women and their husbands, and women's occupation, place of residence and religion. Programmes to help and motivate girls to stay in school will not only reduce early marriage but will also support overall societal development. The rigid enforcement of the legal minimum age at first marriage could be critical in decreasing child marriage.

    In this study, immunization against chicken leptin receptor (cLEPR) extracellular domain (ECD) was applied to investigate leptin regulation and LEPR biofunction in growing chicken pullets. A recombinant protein (cLEPR ECD) based on the cLEPR complemenary DNA sequence corresponding to the 582nd to 796th amino acid residues of cLEPR mature peptide was prepared and used as antigen. Immunization against cLEPR ECD in growing chickens increased anti-cLEPR ECD antibody titers in blood, enhanced proportions of phosphorylated janus kinase 2 (JAK2) and served as signal transducer and activator of transcription 3 (STAT3) protein in liver tissue. Chicken live weight gain and abdominal fat mass were significantly decreased (P chickens. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Chicken is a major food source for humans, hence it is important to understand the mechanisms involved in nutrient absorption in chicken. In the gastrointestinal tract (GIT, the microbiota plays a central role in enhancing nutrient absorption and strengthening the immune system, thereby affecting both growth and health of chicken. There is little information on the diversity and functions of chicken GIT microbiota, its impact on the host, and the interactions between the microbiota and host. Here, we review the recent metagenomic strategies to analyze the chicken GIT microbiota composition and its functions related to improving metabolism and health. We summarize methodology of metagenomics in order to obtain bacterial taxonomy and functional inferences of the GIT microbiota and suggest a set of indicator genes for monitoring and manipulating the microbiota to promote host health in future.

    Full Text Available Bangladesh is a small country with enormous natural beauty and cultural attractions. These gorgeous natural and cultural traits make this country as one of the important tourist destinations in the world but, this potentiality has been overlooked. The tourism industry is facing several challenges, and development efforts of this industry are not sustainable. This paper maps out a way to sustainable growth of the tourism industry in Bangladesh using the SWOT (strengths, weaknesses, opportunities and threats model and a derived matrix out of it. The data used for this study were derived from multiple sources, including literature review and interviews with professionals. To analyze strategic factors of the tourism industry in the country, internal strengths and weaknesses as well as external opportunities and threats were determined to be followed by development of strategic planning based on the SWOT matrix. Results showed that existing tourism activities in Bangladesh are unsustainable. To develop a sustainable tourism industry to attract tourists, this study suggests different WT (weaknesses- threats strategies such as ensuring safety and security of tourists, effective planning for sustainable economic benefits, strict implementation of environmental regulations for ecological sustainability, alerting people about the importance of sustainable tourism development, and infrastructure development. Perhaps the findings of this study would be important in the effort to develop and promote a sustainable tourism industry in beautiful Bangladesh.

    Rotavirus is the leading cause of severe diarrhea in infants and young children worldwide including Bangladesh. Unlike what was seen in high-income countries, the licensed rotavirus vaccines did not show high efficacy in Bangladeshi trials. We assessed rotavirus prevalence and genotypes in Bangladesh over six-year period to provide baseline information on the rotavirus burden and changing profile in the country. This study was conducted from June 2006 to May 2012 in Matlab, Bangladesh. Group A rotaviruses were detected in stools collected from diarrhea patients by ELISA and genotyped using multiplex reverse transcription PCR followed by nucleotide sequencing. Of the 9678 stool samples, 20.3% were positive for rotavirus. The most predominant genotype was G1P[8] (22.4%), followed by G9P[8] (20.8%), G2P[4] (16.9%) and G12P[8] (10.4%). Mixed infections were detected in 14.2% of the samples. Emergence of an unusual strain, G9P[4] was documented during 2011-12. Several amino acid mismatches in the antigenic epitopes of VP7 and VP4 between Bangladeshi and the vaccine strains were identified. Our study provides important information on rotavirus genotypes that should be considered for the selection and introduction of rotavirus vaccines in Bangladesh.

    2015-06-01

    Full Text Available A product is anything that can be accessible to the market for satisfaction. The basic objective of marketing is maximum satisfaction since satisfaction of consumer and business performance is positively related to each other. For satisfaction, product is diversified in different categories i.e. generic product, product type product, substitute product and product line etc. Sachet product is one of the expansions of product line. The term ‘Sachet’ is originated from the French word which means “mini”. In Bangladesh, sachet product has a strong market share. Thus, this study attempts to determine the exiting share of sachet product and measure the impact of marketing strategies on sachet product in Bangladesh. This study uses the selective 22 dimensions to favor the sachet product on the basis of 4Ps (Product, Price, Place and Promotion. To accomplish the study, 125 samples have been taken from selective markets in Cosmopolitan city, Chittagong. The study found that sachet product has strong market position comparative with other categories of products, where promotional effect is the dominant factor who played the vital role to sustain the sachet product in Bangladesh. The results of this study will be constructive for executives and policy-makers of business organization who works with fast moving consumer good (FMCG items effectively in Bangladesh.

    Arsenic (As) causes health concerns due to its significant toxicity and worldwide presence in drinking water and groundwater. The major sources of As pollution may be natural process such as dissolution of As-containing minerals and anthropogenic activities such as percolation of water from mines, etc. The maximum contaminant level for total As in potable water has been established as 10 µg/L. Among the countries facing As contamination problems, Bangladesh is the most affected. Up to 77 million people in Bangladesh have been exposed to toxic levels of arsenic from drinking water. Therefore, it has become an urgent need to provide As-free drinking water in rural households throughout Bangladesh. This paper provides a comprehensive overview on the recent data on arsenic contamination status, its sources and reasons of mobilization and the exposure pathways in Bangladesh. Very little literature has focused on the removal of As from groundwaters in developing countries and thus this paper aims to review the As removal technologies and be a useful resource for researchers or policy makers to help identify and investigate useful treatment options. While a number of technological developments in arsenic removal have taken place, we must consider variations in sources and quality characteristics of As polluted water and differences in the socio-economic and literacy conditions of people, and then aim at improving effectiveness in arsenic removal, reducing the cost of the system, making the technology user friendly, overcoming maintenance problems and resolving sludge management issues.

It was further reorganized, made an autonomous research organization under the Ministry of Agriculture in 1982 and renamed as Bangladesh Institute of Nuclear Agriculture. The other organizations involved in nuclear agricultural research are Institute of Food and Radiation Biology and Bangladesh Agricultural University. A number of technologies have been developed using nuclear techniques that imparted on agricultural development. Sixteen new crops were developed using physical (200-700 Gy gamma rays) and chemical mutagen (NaN 3 ). Soil fertility and plant nutrition technologies were developed using both stable and radio isotopes. The improved feeding strategies and utilization of locally available low quality feed material (rice straw) were determined using 51 Cr-EDTA and 125 I in order to have better livestock growth and reproduction ability. Several constraints related to nuclear research were identified. Increased government commitment and international cooperation are of the utmost importance for effective utilization of the benefits of nuclear technology and to face the increasing demand for food for the ever increasing population in years to come

    Full Text Available This paper analyses how the media interprets Bangladeshian fertility trends by analyzing 11 online available articles from two Bangladeshi leading dailies, The Daily Star and the Prothom Alo. The exploration of the newspaper articles reveals that print media in Bangladesh has shown concern notably on the present scenario of the country’s declining fertility trend. It has been observed from the newspaper clippings that both population growth rate and fertility rate are gradually declining in Bangladesh which they explain as a matter of great satisfaction. Drawing on examples from South Asia, the articles explain that Bangladesh has a remarkable achievement in fertility reduction compared to India and Pakistan. However, almost all of the articles have expressed concern over the population bomb of Bangladesh. The newspapers also report that though fertility is declining at the national level, significant variation exists at the regional level and among different socio economic groups. The fertility rate is reported to be very high in the urban shanties and poverty-stricken rural areas. In this regard, the clippings have often criticized the government activities, especially governmental population control programme.

    Full Text Available Since late 2000s, the political landscape in Bangladesh moved from democracy to an authoritarian kleptocracy, and experienced a new set of political and social narratives. This paper aims to contest some of these dominant/official narratives which have been discursively constructed and promoted by the secularist parties (including the ruling regime and groups in Bangladesh over recent years. Examining the sociopolitical and historical facts and figures of the country, we have identified five major contested narratives related to (a Bengali nationalism in East Pakistan, (b foundational ideology of Bangladesh’s war of liberation, (c state-sponsored Islamization in Bangladesh, (d pro-liberation and anti-liberation dichotomy, and (e war crimes trial. Drawing on a robust content analysis of the credible secondary sources substantiated by qualitative interviews, we have examined these dominant narratives and found that they are not supported by historical evidence and popular mandate, yet have been constructed largely to support and legitimize the current authoritarian regime. The paper offers both counter-narratives and some pragmatic policy recommendations to elude increasing polarization and sociopolitical instability and foster a peaceful democratic society in Bangladesh.

    2013-07-01

    Full Text Available The paper investigates whether the stock market of Bangladesh can be related with the last world recession. The Pearson’s correlation analysis model was used to find the correlation between the Dhaka Stock Exchange General index and real GDP growth rate of the world. The findings show that no statistically significant correlation exists between the two variables inferring that the stock market of Bangladesh was not significantly affected by ‘the great recession’ (2007-2009. The findings of this study are inconsistent with the results of previous studies which claimed that the Bangladesh stock market shares a common stochastic trend with the capital market of USA. The results of this study may be explained mainly by domestic factors such as low market capitalization, market inefficiency, strict monitoring and control by the Security and Exchange Commission and low international participation in the stock market of Bangladesh. All these factors, along with the inconsistency with past results, instigate further investigation.

    Full Text Available Bangladesh and Nepal lie between the Himalayas and low-lying coasts of the Bay of Bengal and are traversed by hundreds of rivers and tributaries. Historical data shows that, since 1970, the scale, intensity and duration of floods have increased in Bangladesh and Nepal, causing grave human suffering; disruptions in normal life and activity, damages of infrastructure, crops and agricultural land with severe impacts on the economy. Bangladesh is affected by torrential rain, glacier melt, upstream water flow and tidal surges. In 1988, Bangladesh experienced one of the most severe floods of the twentieth century which aroused significant concern internationally and triggered the Bangladesh Action Plan for Flood Control. The Government of Bangladesh (GOB has so far constructed a number of flood shelters and carried out 482 water and flood control projects involving flood protection embankments, drainage channels, sluice gates and regulators on different rivers and canals. These also provided safety measures against inundation by tidal waves, storm-surges and flooding. The Terai region of Nepal is highly prone to hydrological risks including torrential rain, floods, glaciers resulting in erosion and landslides. The Government of Nepal (GON has implemented different mitigation measures mainly early warning awareness, rescue measure, relief, and post-flood rehabilitation programs etc. Disaster Management Bureaus of both the countries have already conducted many trainings, workshops and seminars to disseminate scientific knowledge and coping up practices to disaster managers and to create public awareness. Besides the contemporary approaches to mitigating flood effects, people of these countries have coped with floods through generations relying on traditional/indigenous knowledge and other local adaptation practices. It is crucial that along with scientific process, indigenous, traditional and conventional practices are to be integrated for a national

  12. MCU-Based Solar Powered Chicken Feeder

    Elenor M. Reyes

    2015-12-01

    Full Text Available Poultry is a great potential industry particularly in Batangas Province. The method of feeding chicken needs to be considered as chicken must be fed regularly to be more productive. The conventional method of feeding chicken is the need to continuously provide the food, be alert and conscious on the food remaining in cages and to feed the chickens in a correct period of time to avoid the decline of the production. Growers also find it difficult to manage their businesses effectively because they need to be around the cages every now and then to monitor the poultry. Timing and exactness are the key to provide a uniform time in feeding the chickens. This will benefit the owner of the business in terms of time and effort. Another advantage of this project is in terms of savings to the owner of the poultry business. This technology was designed to automatically feed chickens at a given period of time and to give alarm when the feeds are running out of supply. The power to be supplied to this prototype will be drawn from the sun by means of solar panels and will be stored in typical car battery. The feeds will be stored in a container and evenly distributed by using a conveyor to the feeding basin of the poultry. It will be more efficient than manual conventional way of feeding because less effort will be needed in feeding the chickens and less feeds will be wasted. In addition to that, the stored power can also be used for lighting purposes for the growers to save energy and energy bills.

    Md. Inkeyas Uddin

    2016-10-01

    Full Text Available Aim: Worldwide, Mycoplasma synoviae (MS is an important pathogen of poultry, especially for chicken and turkey. It causes respiratory tract infection and infectious sinusitis. The study was conducted to determine the seroprevalence of MS infection with associated risk factors and identification of MS organism in unvaccinated flocks of commercial breeder farms of the Chittagong district, Bangladesh. Materials and Methods: A total of 365 serum samples were collected and tested for MS using serum plate agglutination (SPA test for determination of MS seroprevalence. On the other hand, tracheal swabs were collected from each seropositive flocks for polymerase chain reaction (PCR to determine the presence of MS organism. Results: Among the farms, the highest prevalence was found to be 69% and the lowest prevalence was 28% with the average 60%. The seroprevalence of MS infection in breeder farms was highest 70% with the flock size >10,000 birds, whereas it was lowest 57% in the flocks ranging from 4000 to 7000. According to age group, the prevalence was found highest 70% in >60 weeks age group of birds and lowest 42% in 10-19 weeks group. The seroprevalence of MS in winter season was found as highest as 64%, whereas it was found lowest 60% in the summer season. There was a statistically significant difference (p0.05 difference in the winter, summer, and rainy season. To confirm the presence of MS in the samples, PCR test was applied using specific primers to amplify a 214 bp region of the 16S rRNA gene of the organism. In PCR, all seropositive flocks showed a positive result for MS. Conclusion: As the plate agglutination test result showed 100% similar with PCR result, it can be suggested that agglutination test is better than molecular and culture techniques for MS detection and it is also cheaper and less time-consuming method.

  14. Welcoming Wind Turbines and the PIMBY ("Please in My Backyard") Phenomenon: The Culture of the Machine in the Rural American Midwest.

    Science.gov (United States)

    Brinkman, Joshua T; Hirsh, Richard F

    This article argues that the welcoming of wind turbines in midwestern farming communities, the so-called PIMBY ("Please in My Backyard") phenomenon, constitutes only the most recent expression of a historical process of farmers forming an ultramodern identity, one that still goes largely unappreciated by relatively backward city residents. We conclude that farmers undertook a two-step process to develop a modern identity that incorporated rural values. In the first step, beginning early in the twentieth century, agrarians employed a discourse of rural capitalistic modernity to combat urban yokel stereotypes within the context of a broader rural-urban conflict. This rural capitalistic modernity strengthened during the cold war until it transformed, in the second step, into the current ultramodern discourse. Wind turbines, in addition to providing economic benefits, function ontologically to maintain an identity of rural citizens as savvy producers and users of technology, and to deflect stereotypes imposed by their urban cousins.

    This research was conducted to investigate the effect of chicken feed additives (antibiotic, Lacto-lase® and probiotic) on protein and fat content of chicken meat. Chicken fed with control diet (corn-soy based diet) served as a control. The treated diets were added with zinc bacitracin (antibiotic), different amount of Lacto-lase® (a mixture of probiotic and enzyme) and probiotic. Chicken were slaughtered at the age of 43-48 days. Each chicken was divided into thigh, breast, drumstick, drumette and wing. Protein content in chicken meat was determined by using macro-Kjeldahl method meanwhile Soxhlet method was used to analyse fat content. The result of the study showed that the protein content of chicken breast was significantly higher (p≤0.05) while thigh had the lowest protein content (p≤0.05). Antibiotic fed chicken was found to have the highest protein content among the treated chickens but there was no significant different with 2g/kg Lacto-lase® fed chicken (p>0.05). All thighs were significantly higher (p≤0.05) in fat content except for drumette of control chicken while breast contained the lowest fat content compared to other chicken parts studied. The control chicken meat contained significantly higher (p≤0.05) amount of fat compared to the other treated chickens. Chicken fed with 2g/kg Lacto-lase® had the lowest (p≤0.05) fat content. The result of this study indicated that the addition of Lacto-lase® as a replacement of antibiotic in chicken feed will not affect the content of protein and fat of chicken meat.

    Bangladesh has one of the lowest per capita energy resources and consumption of energy. The per capita GDP of Bangladesh is also one of the lowest in the world. In view of this situation, the need and importance of nuclear power in providing cheaper and reliable energy for economic development of the country is discussed. Constraints being faced by the Bangladesh Atomic Energy Commission (BAEC) in the initiation and development of a national nuclear power programme are dealt with. Following liberation of the country in 1971, its financial resources were mainly channelled for rehabilitation and restoration of its economy. As the size of the national grid has remained relatively small, unit sizes in the range of 100-200 MWe only could be considered for commissioning during the next decade. Lack of vendor interest in such small sizes and the difficulty of arranging long-term investment for nuclear station are the main constraints being faced by the BAEC. Other bottlenecks are due to the uncertainty about the nature and extent of future economic development, pricing policy for available indigenous fossil fuel, national energy planning criteria which are mainly influenced by financial resource constraint, drainage of trained man-power, national priority for various essential non-development expenditures which use up most of the country's own earnings and foreign aid, etc. The effect of the growth of opposition to nuclear power in developed countries on the public acceptability of nuclear power in Bangladesh is analysed. The paper also examines the prospective growth of a cartel of nuclear-exporting countries and its possible effect upon Bangladesh

  17. Exploring standardized precipitation evapotranspiration index for drought assessment in Bangladesh.

    Drought is a critical issue, and it has a pressing, negative impact on agriculture, ecosystems, livelihoods, food security, and sustainability. The problem has been studied globally, but its regional or even local dimension is sometimes overlooked. Local-level drought assessment is necessary for developing adaptation and mitigation strategies for that particular region. Keeping this in understanding, an attempt was made to create a detailed assessment of drought characteristics at the local scale in Bangladesh. Standardized precipitation evapotranspiration (SPEI) is a new drought index that mainly considers the rainfall and evapotranspiration data set. Globally, SPEI has become a useful drought index, but its local scale application is not common. SPEI base (0.5° grid data) for 110 years (1901-2011) was utilized to overcome the lack of long-term climate data in Bangladesh. Available weather data (1955-2011) from Bangladesh Meteorology Department (BMD) were analyzed to calculate SPEI weather station using the SPEI calculator. The drivers for climate change-induced droughts were characterized by residual temperature and residual rainfall data from different BMD stations. Grid data (SPEI base ) of 26 stations of BMD were used for drought mapping. The findings revealed that the frequency and intensity of drought are higher in the northwestern part of the country which makes it vulnerable to both extreme and severe droughts. Based on the results, the SPEI-based drought intensity and frequency analyses were carried out, emphasizing Rangpur (northwest region) as a hot spot, to get an insight of drought assessment in Bangladesh. The findings of this study revealed that SPEI could be a valuable tool to understand the evolution and evaluation of the drought induced by climate change in the country. The study also justified the immediate need for drought risk reduction strategies that should lead to relevant policy formulations and agricultural innovations for developing

    Full Text Available Vibrio cholerae infections cluster in households. This study's objective was to quantify the relative contribution of direct, within-household exposure (for example, via contamination of household food, water, or surfaces to endemic cholera transmission. Quantifying the relative contribution of direct exposure is important for planning effective prevention and control measures.Symptom histories and multiple blood and fecal specimens were prospectively collected from household members of hospital-ascertained cholera cases in Bangladesh from 2001-2006. We estimated the probabilities of cholera transmission through 1 direct exposure within the household and 2 contact with community-based sources of infection. The natural history of cholera infection and covariate effects on transmission were considered. Significant direct transmission (p-value<0.0001 occurred among 1414 members of 364 households. Fecal shedding of O1 El Tor Ogawa was associated with a 4.9% (95% confidence interval: 0.9%-22.8% risk of infection among household contacts through direct exposure during an 11-day infectious period (mean length. The estimated 11-day risk of O1 El Tor Ogawa infection through exposure to community-based sources was 2.5% (0.8%-8.0%. The corresponding estimated risks for O1 El Tor Inaba and O139 infection were 3.7% (0.7%-16.6% and 8.2% (2.1%-27.1% through direct exposure, and 3.4% (1.7%-6.7% and 2.0% (0.5%-7.3% through community-based exposure. Children under 5 years-old were at elevated risk of infection. Limitations of the study may have led to an underestimation of the true risk of cholera infection. For instance, available covariate data may have incompletely characterized levels of pre-existing immunity to cholera infection. Transmission via direct exposure occurring outside of the household was not considered.Direct exposure contributes substantially to endemic transmission of symptomatic cholera in an urban setting. We provide the first estimate of

    2018-04-01

    Despite descriptions of runting-stunting syndrome (RSS) in broiler chickens dating back over 40 years, the aetiology has not yet been described. A novel chicken astrovirus (CkAstV) was isolated in an LMH liver cell line from the intestines of chickens affected with RSS. Clinical RSS is characterized by retarded growth and cystic crypt lesions in the small intestine. In 1-day-old broiler chickens infected with the CkAstV isolate, virus was only detected in the intestinal epithelial cells during the first few days after infection. Notably, the preferred host cells are the crypt epithelial cells following initial replication in the villous epithelial cells, thus implying viral preference for immature intestinal cells. Nevertheless, the CkAstV isolate did not induce remarkable pathological changes, despite the presence of the virus in situ. Serial chicken-to-chicken passages of the virus induced increased virulence, as displayed by decreased weight gain and the presence of cystic lesions in the small intestine reproducing clinical RSS in chickens. The analysis of the full-length genome sequences from the isolated CkAstV and the CkAstV from the bird-to-bird passages showed >99 % similarity. The data obtained in this study suggest that the CkAstV isolate is capable of inducing RSS following serial bird-to-bird passages in broilers and is as an aetiological agent of the disease.

    Mitochondrial DNA has the characteristic of quick evolution, matrilineal inheritance, and simple molecular structure, and it serves as the most used marker for molecular study. As an important role of genomics, studying it can help understand the origins, history, and adaptation of domestication. Because of its wide spread popularity, chicken is one of the important domestic animals, which provides humans with a stable source of protein, including both meat and eggs. This article reviews recent studies of chicken mitochondrial DNA. Mitochondrial D-loop and mitochondrial genomics pinpoint the geographic origins of the domestic chicken which was multiple origins; moreover, the mitochondria gene mutation has an association with high-altitude adaptation and the mitochondria-associated diseases' study in poultry is not performed.

    2009-10-01

    Full Text Available Abstract Background Modeling results from chicken microarray studies is challenging for researchers due to little functional annotation associated with these arrays. The Affymetrix GenChip chicken genome array, one of the biggest arrays that serve as a key research tool for the study of chicken functional genomics, is among the few arrays that link gene products to Gene Ontology (GO. However the GO annotation data presented by Affymetrix is incomplete, for example, they do not show references linked to manually annotated functions. In addition, there is no tool that facilitates microarray researchers to directly retrieve functional annotations for their datasets from the annotated arrays. This costs researchers amount of time in searching multiple GO databases for functional information. Results We have improved the breadth of functional annotations of the gene products associated with probesets on the Affymetrix chicken genome array by 45% and the quality of annotation by 14%. We have also identified the most significant diseases and disorders, different types of genes, and known drug targets represented on Affymetrix chicken genome array. To facilitate functional annotation of other arrays and microarray experimental datasets we developed an Array GO Mapper (AGOM tool to help researchers to quickly retrieve corresponding functional information for their dataset. Conclusion Results from this study will directly facilitate annotation of other chicken arrays and microarray experimental datasets. Researchers will be able to quickly model their microarray dataset into more reliable biological functional information by using AGOM tool. The disease, disorders, gene types and drug targets revealed in the study will allow researchers to learn more about how genes function in complex biological systems and may lead to new drug discovery and development of therapies. The GO annotation data generated will be available for public use via AgBase website and

    Knowledge and awareness concerning sexually transmitted diseases (STDs) has become the burning issue of the day. Although STDs pose serious risks to health security, there is very little literature quantifying the knowledge and awareness of these diseases and their principal socioeconomic determinants. The aim of this study is to determine the effect of different socio-economic and demographic factors on knowledge and awareness about STDs among women in Bangladesh. This is a cross-sectional study using data from the Bangladesh Demographic and Health Survey (BDHS) 2011. It involves 10,996 women in six divisions of Bangladesh - Dhaka, Rajshahi, Chittagong, Barisal, Khulna and Sylhet. In this study, the percentage distribution and logistic regression model are used to identify which factors are associated with knowledge and awareness among women in Bangladesh about STDs. There is a significant association between geographic division (Dhaka: OR = 1.669, 95% CI = 0.89-2.10, Khulna: OR = 2.234, 95% CI = 1.2-3.2); places of residence (Rural: OR = 0.363, 95% CI = 0.20-1.08), respondent's age (20-29 years: OR = 1.331; 95% CI = 0.98-2.31); education (Primary: OR = 2.366, 95% CI = 1.98-3.1, secondary: OR = 10.089, 95% CI = 8.98-12.77, higher: OR = 20.241, 95% CI = 18.33-22.65); listening to radio (OR = 1.189, 95% CI = 1.29-3.12) and watching TV (OR = 2.498, 95% CI = 2.22-4.09) with knowledge and awareness among women in Bangladesh about STDs. There is a need to improve the education in Bangladesh about STDs particularly among those in the rural areas and older ages of women (30-49 years). Formal, informal and special educational knowledge and awareness programmes may be implemented to educate people concerning STDs in Rajshahi, Sylhet and Chittangong division. Campaigns and mass media can be used to increase the knowledge and awareness among the community, especially among women. Policies concerning the issue of STDs need to be improved and can be emphasized in collaboration

    The concentrations and enantiomer fractions (EFs) of α-, β-, and γ-hexabromocyclododecanes (HBCDs) were measured in chicken diet sources (soil and chicken feed), home-raised adult chicken (Gallus domesticus) tissues, eggs during incubation, and hatchling chicken tissues. HBCD concentrations were not detected-0.69 ng/g dry weight (dw) and 25.6-48.4 ng/g dw in chicken feed and soil, respectively. HBCDs were detected in all adult chicken tissues, except the brain, at median levels of 13.1-44.0 ng/g lipid weight (lw). The proportions of α-HBCD in total HBCDs increased from 51% in soil to more than 87% in adult chicken tissues. The accumulation ratios (ARs) of α-HBCD from diet to adult chicken tissues were 4.27 for liver, 11.2 for fat, and 7.64-12.9 for other tissues, respectively. The AR and carry-over rate (COR) of α-HBCD from diet to eggs were 22.4 and 0.226, respectively. The concentrations of α-HBCD in hatchling chicken liver (median: 35.4 ng/g lw) were significantly lower than those in hatchling chicken pectoral muscle (median: 130 ng/g lw). The EFs of α-HBCD decreased from soil to adult chicken tissues and from eggs to hatchling chicken liver. Meanwhile, the EFs of γ-HBCD increased from soil to adult chicken tissues. These results indicate the preferential enrichment of (-)-α-HBCD and (+)-γ-HBCD in chickens. The alteration of diastereoisomeric and enantiomeric patterns of HBCDs might be influenced by the different absorption and elimination rates of the six HBCD enantiomers as well as variations in HBCD metabolism in chickens.

    Full Text Available A detailed study on histopathological lesions induced by two C. psittaci outer membrane protein A (ompA genotype B strains (10/423 and 10/525 and one genotype D strain (10/298 in experimentally infected (aerosol specific pathogen free (SPF chickens was performed. The strains were derived from Belgian and French commercially raised broilers with pneumonia. Both genotype B and D strains induced conjunctivitis, rhinitis, sinusitis, tracheitis, bronchitis, pneumonitis, airsacculitis, splenitis, hepatitis, nephritis, and enteritis in sequentially (days 2 to 34 post infection euthanized chickens. Inflammation of the ovaries was only observed in genotype D infected chickens. Overall, the genotype D strain caused more severe gross and histopathological lesions and mortality (54.5% early upon infection. The genotype D strain seemed to replicate faster as severity of the lesions increased more quickly. C. psittaci is a primary pathogen in chickens, and efficient monitoring and control of this emerging zoonotic pathogen is urgently needed.

    The genotypes and oxacillin resistance of 263 Staphylococcus aureus isolates cultured from chicken cloacae (n = 138) and chicken meat (n = 125) was analyzed. Fifteen spa types were determined in the studied S. aureus population. Among 5 staphylococcal protein A gene (spa) types detected in S. aureus from chicken, t002, t3478, and t13620 were the most frequent. Staphylococcus aureus isolates from meat were assigned to 14 spa types. Among them, the genotypes t002, t056, t091, t3478, and t13620 were dominant. Except for 4 chicken S. aureus isolates belonging to CC398, the remaining 134 isolates were clustered into multilocus sequence clonal complex (CC) 5. Most of meat-derived isolates were assigned to CC5, CC7, and CC15, and to the newly described spa-CC12954 complex belonging to CC1. Except for t011 (CC398), all other spa types found among chicken isolates were also present in isolates from meat. Four S. aureus isolated from chicken and one from meat were identified as methicillin-resistant S. aureus (MRSA) with oxacillin minimum inhibitory concentrations from 16 to 64 μg/mL. All MRSA were assigned to spa types belonging to ST398, and included 4 animal spa t011 SCCmecV isolates and 1 meat-derived spa t899, SCCmecIV isolate. Borderline oxacillin-resistant S. aureus (BORSA) isolates, shown to grow on plates containing 2 to 3 μg/mL of oxacillin, were found within S. aureus isolates from chicken (3 isolates) and from meat (19 isolates). The spa t091 and t084 dominated among BORSA from chicken meat, whereas t548 and t002 were found within animal BORSA. We report for the first time the presence of MRSA in chicken in Poland. We demonstrate that MRSA CC398 could be found in chicken meat indicating potential of introduction of animal-associated genotypes into the food chain. We also report for the first time the possibility of transmission of BORSA isolates from chicken to meat. ©2014 Poultry Science Association Inc.

    In recent years, obtaining the natural protein fibers from chicken feathers, which are obtained as a by-product in the production of chicken meat and which cause environmental pollution and important part is waste, has been drawn to the perspective of scientists. So, the investigations about the chicken feather fibers reveal important properties of these fibers. Chicken feather fibers are obtained by mechanical cutting of the barbs which have fibrous structure, the structure branched from rachis and constitute the body of the feather. The rachis part of chicken feather constitutes approximately half of the weight of the feathers. So, it is necessary to examine the properties of the chicken feathers in order to gain their industrialization. This study is concerned with the mechanical and physical properties of the material that is taken as a by-product in the production of fibers from chicken feathers and constitutes the rachis part of the feathers.

    Garment workers in Bangladesh producing clothing for international brands have experienced repeated factory fires and building collapses in the last 10 years, resulting in more than 1,600 deaths and hundreds of disabling injuries. After the Tazreen Fashion fire in December 2012 and the Rana Plaza building collapse in April 2013, more than 190 international clothing brands and retailers signed an "Accord on Fire and Building Safety" with two international union federations. Full implementation of the provisions of the Accord would change "business as usual" in Bangladesh's garment industry and set a positive example for other countries and other industries with global supply chains. The components, challenges, and controversies of the Accord are detailed in the article. © 2015 SAGE Publications.

    Full Text Available This paper attempts to investigate the relationship among economic growth, energy consumption, CO2 emission, FDI and natural gas usage in Bangladesh through co-integration and Vector Error Correction model (VECM over the period 1978 to 2010. Using ADP unit root tests it is found that all the four variables are integrated in first difference. The Johansen co-integration tests indicate that there is existence of long-run relationship among the variables. The VECM long run causality model indicates that there is a long run causality running from energy consumption and natural gas usage by industrial sector to GDP as well as from CO2 emission to FDI. Likewise in the short run a causal relationships have also been found among the variables. Moreover our model is found be error free based on several statistical test. Our results provide important policy suggestions regarding our foreign direct investment, environmental issues and economic growth nexus in Bangladesh.

    The incidence of peptic ulcer has steadily declined through out the world. This decreasing trend is also noticeable in this subcontinent. The point prevalence of peptic ulcer (PUD) in Bangladesh was around 15% in eighties. The aim of this study was to see the present prevalence of peptic ulcer at endoscopy and to identify changing trends in the occurrence of peptic ulcer in Bangladesh. This retrospective analysis of the endoscopic records of multiple tertiary referral centres of Dhaka city were done from January 2012 to July 2013. A total of 5608 subjects were the study samples. We included those patients having peptic ulcer in the form of duodenal ulcer, benign gastric ulcer including pre-pyloric ulcer and gastric outlet obstruction due to peptic ulcer. Duodenal ulcer and benign gastric ulcer were found in 415(7.4%) and 184(3.28%) patients respectively and gastric outlet obstruction due to peptic ulcer was found in 23(0.40%) patients.

    Full Text Available As a consequence of rapid industrialization, the waterbodies of Bangladesh have transformed into seasonal dead zones from the ensuing pollution. Despite having environmental regulations to control industrial pollution, lack of effective enforcement has jeopardized environmental quality. Evaluation of enforcement mechanisms have not gained attention from researchers until recently. This qualitative and descriptive analysis illustrates the current enforcement regime for environmental compliance in Bangladesh focusing on fines levied on polluters. Although there are no official guidelines for fines based on type of violation, this paper identified that there are differences of fines among violation based on historical data. It was also found that textile factories are not penalized heavily compared to non-textile factories. Repeat offenders were found to be penalized at the same rate. This study can be used to design appropriate penalty structure based on violation types, and reform the enforcement system so that polluters pay principle is actually implemented.

    The role of in-house transmission on the incidence of Vibrio cholerae, the deadly waterborne pathogen, is still not developed. The aim of the current study was to investigate possible contamination routes in household domain for effective cholera control in Bangladesh. To examine the prevalence....... cholerae El Tor strain N16961, showed hemolysis and proteolysis activity but none of them exhibited any hemagglutinin activity on human erythrocytes. The study findings indicate that V. cholerae contamination is mostly originated in and around kitchen area rather than latrine area. Contaminated food...... and water supply may be the reason behind this relatively high presence of virulence factors in food plates and water pots. Direct exposure routes of disease transmission should be a major consideration in cholera prevention policies. Investigation of household contamination of Vibrio cholerae in Bangladesh...

    Full Text Available Climate change, the effects of greenhouse effect and global warming, is out to alter the global map with its devouring prospects of sending a number of countries under the waves. Unfortunately yet unavoidably, Bangladesh stands at the forefront of climate forays. Its land, water and weather are being severely affected by undesirable climatic changes. Alarmingly, the dangers are to be intensified unless the trend is reversed. However, local initiative will hardly be enough to offset the grave concerns of unintended climatic changes in Bangladesh. The changes will also impact the socio-economic conditions of the country, putting the future of the nation on the line. Some ominous signs are already there for the concerned to respond with required amount of fervour.

    Maloney, C

    1985-01-01

    Bangladeshis of varying background all over the country were asked why they think poverty persists to such an extent in Bangladesh. Their answers provide a new perspective on the situation. The initial response often blames outside and natural causes -- floods, droughts, lack of resources, low demand for the country's exports, or historic exploitation. It is true that Bangladesh has virtually no mineral resources except gas. Yet, the soil, water, and human labor add up to a huge potential. The Third Five Year Plan emphasizes use of the soil, irrigation, tanks, rivers, and human labor. These provide the only hope for reducing poverty a little during the next 5 years. Bangladeshis as well as foreign observers most commonly cite overpopulation as the cause of poverty. Population growth is a cause of present poverty in Bangladesh but is not the only cause of poverty. The Third Five Year Plan goal to reduce annual growth to 1.8% is ambitious, but even if it is achieved the population will double in a few decades. As it would most likely be impossible for Bangladesh to support such numbers and maintain political and economic stability, such growth will have to be prevented. Poverty in Bangladesh is party a result of the long history of low urbanization, weak institutions, spotty and inadequate physical infrastructure, and insufficient entrapreneurship. Other reasons cited as causes of persisting poverty include illiteracy, idleness, class exploitation, the selfishness of individuals, and a lack of trust among people. All of the efforts of the poor themselves, various agencies, and the government, as examined in the 1st part of this discussion, fail to indicate any reason to hope that poverty in Bangladesh can be dramatically reduced any time soon. The Third Five Year Plan foresees a possible reduction of the number of those in poverty by 10%. According to the Plan itself, those in or near poverty comprise 85% of the people. The conditions under which the people of some

  11. Growth hormone (GH)-releasing activity of chicken GH-releasing hormone (GHRH) in chickens.

    2014-08-01

    Two peptides with sequence similarities to growth hormone releasing hormone (GHRH) have been identified by analysis of the chicken genome. One of these peptides, chicken (c) GHRH-LP (like peptide) was previously found to poorly bind to chicken pituitary membranes or to cloned and expressed chicken GHRH receptors and had little, if any, growth hormone (GH)-releasing activity in vivo or in vitro. In contrast, a second more recently discovered peptide, cGHRH, does bind to cloned and expressed cGHRH receptors and increases cAMP activity in transfected cells. The possibility that this peptide may have in vivo GH-releasing activity was therefore assessed. The intravenous (i.v.) administration of cGHRH to immature chickens, at doses of 3-100 μg/kg, significantly increased circulating GH concentrations within 10 min of injection and the plasma GH levels remained elevated for at least 30 min after the injection of maximally effective doses. The plasma GH responses to cGHRH were comparable with those induced by human (h) or porcine (p) GHRH preparations and to that induced by thyrotropin releasing hormone (TRH). In marked contrast, the i.v. injection of cGHRH-LP had no significant effect on circulating GH concentrations in immature chicks. GH release was also increased from slaughterhouse chicken pituitary glands perifused for 5 min with cGHRH at doses of 0.1 μg/ml or 1.0 μg/ml, comparable with GH responses to hGHRH1-44. In contrast, the perifusion of chicken pituitary glands with cGHRH-LP had no significant effect on GH release. In summary, these results demonstrate that cGHRH has GH-releasing activity in chickens and support the possibility that it is the endogenous ligand of the cGHRH receptor.

    Niels-Hugo Blunch

    2015-01-01

    Full Text Available Background: While norms are important for educational attainment, especially in the developing world, there are relatively few studies on this topic. This paper, which explores attitudes toward gender equality in education among Bangladeshis, should therefore be of interest to both academics and policymakers. Objective: In this paper, we seek to identify which factors affect the norms regarding the education of girls and boys, as well as of women and men, across two cohorts of married women in Bangladesh. In particular, we look at the relative importance of an individual woman's own educational background and those of her spouse and other family members in shaping her attitudes toward gender equality in education. Methods: We analyze a rich household dataset for Bangladesh from the World Bank Survey on Gender Norms in Bangladesh, which was conducted in 2006. We use linear probability models to examine the determinants of gender education norms. We also decompose the intergenerational gender norms gap using the Oaxaca-Blinder composition (total and detailed, taking into account several technical issues related to the computation of standard errors and the use of dummy variables in detailed decompositions. Results: Education norms were found to differ substantially across cohorts, with women from the younger cohort expressing far more positive views than older female respondents regarding education for both girls and women. The effect of education on norms could be found among both the respondents and their husbands, as well as among the older women in the household. This suggests that educational norms are shared both within married couples and across generations. Conclusions: Our results indicate that the far-reaching changes in female education in Bangladesh have had equally far-reaching effects on the perceived value of education for girls relative to education for boys.

  13. Bangladesh : Fiscal Costs of Non-Financial Public Corporations

    OpenAIRE

    Kojo, Naoko C.

    2010-01-01

    The overall fiscal position of Bangladesh looks sustainable, but there are concerns that the country may be trapped in a low revenue-low capital spending equilibrium, which is holding back Bangladesh’s growth potential. Eliminating wasteful spending and halting fiscal drains through inefficient non-financial public corporations (NFPCs) are important ways to create fiscal space, particularly in the area of infrastructure. This paper reviews the financial performance of the NFPC ...

    This study analyzes the trends of extreme rainfall indices over northeast Bangladesh for the period of 1984 to 2016 for the pre-monsoon and monsoon seasons. The research was framed as part of a project co-producing knowledge of climate variability and impacts through collaboration between scientific and local communities in northeast Bangladesh, which found pre-monsoon and monsoon rainfall to be most important. With access to a greater number of rainfall stations than previous work in northeast Bangladesh, we investigated trends in extreme rainfall events using the Mann-Kendall trend test and Sen's slope estimator. To appraise the quality of the data, we used the Standard Normal Homogeneity and the Pettitt tests to check its homogeneity. Among the seven stations, only Sunamganj was found inhomogeneous, and was not considered for trend analysis. All indices of rainfall extremes showed a decreasing trend in both seasons, with the most significant decrease during the monsoon. Importantly, we saw a decreasing trend in the seasonal total rainfall and consecutive wet days, whereas there was an increasing trend in consecutive dry days. Moreover, we saw a decreasing trend in 1-day maximum rainfall, 5-day maximum rainfall, the intensity of the daily rainfall over 25 mm during the pre-monsoon and 50 mm during monsoon, which together may indicate a future decrease in the magnitude and intensity of flash floods and monsoon floods. If this trend continues, the northeast Bangladesh may suffer from water stress, which could affect the lives and livelihoods of communities living there.

    Full Text Available Introduction: The HIV/AIDS epidemic portrays a growing health threat in the world. In Bangladesh, the prevalence rate of HIV/AIDS is not yet high but it is gradually becoming a threat especially for women and young girls due to gender disparity. This systematic review was conducted to explore the gender-specific vulnerability to HIV/AIDS in Bangladesh in order to suggest to policy makers the best way for the prevention of HIV/AIDS in Bangladesh as well as in other low income countries. Methods: Peer review articles were identified using a systematic search of two databases: Pubmed and Goggle Scholar. The search was limited to studies published in English between 1998 and 2016 and included a special focus on articles addressing the gender-specific risk factors to HIV/ AIDS. Discussion and Conclusion: This paper analyzes how women and girls in marginalized position in the society fall victim to HIV/AIDS due to gender disparities and other related issues. The findings of the study indicate that women and young girls are the most vulnerable to HIV/AIDS infection among the general people. Along with biological susceptibility, other major causes of this vulnerability of women and girls are gender inequality, sexual abuse and violence, social stigma, inability to decision making power, economic dependency and men’s sexual power and privilege over women. This paper helps policy makers and invites them to take special care to reduce gender inequality before implementing any policy for the prevention of HIV/AIDS in Bangladesh as well as in low income countries.

    Diarrheal disease is a leading cause of child mortality globally, and rotavirus is responsible for more than a third of those deaths. Despite substantial decreases, the number of rotavirus deaths in children under five was 215,000 per year in 2013. Of these deaths, approximately 41% occurred in Asia and 3% of those in Bangladesh. While Bangladesh has yet to introduce rotavirus vaccination, the country applied for Gavi support and plans to introduce it in 2018. This analysis evaluates the impact and cost-effectiveness of rotavirus vaccination in Bangladesh and provides estimates of the costs of the vaccination program to help inform decision-makers and international partners. This analysis used Pan American Health Organization's TRIVAC model (version 2.0) to examine nationwide introduction of two-dose rotavirus vaccination in 2017, compared to no vaccination. Three mortality scenarios (low, high, and midpoint) were assessed. Benefits and costs were examined from the societal perspective over ten successive birth cohorts with a 3% discount rate. Model inputs were locally acquired and complemented by internationally validated estimates. Over ten years, rotavirus vaccination would prevent 4000 deaths, nearly 500,000 hospitalizations and 3 million outpatient visits in the base scenario. With a Gavi subsidy, cost/disability adjusted life year (DALY) ratios ranged from $58/DALY to $142/DALY averted. Without a Gavi subsidy and a vaccine price of $2.19 per dose, cost/DALY ratios ranged from $615/DALY to $1514/DALY averted. The discounted cost per DALY averted was less than the GDP per capita for nearly all scenarios considered, indicating that a routine rotavirus vaccination program is highly likely to be cost-effective. Even in a low mortality setting with no Gavi subsidy, rotavirus vaccination would be cost-effective. These estimates exclude the herd immunity benefits of vaccination, so represent a conservative estimate of the cost-effectiveness of rotavirus vaccination

    We investigated the amyloidogenic potential of inactivated vaccines and the localized production of serum amyloid A (SAA) at the injection site in white layer chickens. Hens in the treated group were injected intramuscularly three times with high doses of inactivated oil-emulsion Salmonella Enteritidis vaccine and multivalent viral and bacterial inactivated oil-emulsion vaccines at two-week intervals. Chickens in the control group did not receive any inoculum. In the treated group, emaciation and granulomas were present, while several chickens died between 4 and 6 weeks after the first injection. Hepatomegaly was seen at necropsy, and the liver parenchyma showed inconsistent discolouration with patchy green to yellowish-brown areas, or sometimes red-brown areas with haemorrhage. Amyloid deposition in the liver, spleen, duodenum, and at injection sites was demonstrated using haematoxylin and eosin staining, Congo red, and immunohistochemistry. The incidence of chicken amyloid A (AA) amyloidosis was 47% (28 of 60) in the treated group. In addition, RT-PCR was used to identify chicken SAA mRNA expression in the liver and at the injection sites. Furthermore, SAA mRNA was detected by in situ hybridization in fibroblasts at the injection sites, and also in hepatocytes. We believe that this is the first report of the experimental induction of systemic AA amyloidosis in white layer chickens following repeated inoculation with inactivated vaccines without the administration of amyloid fibrils or other amyloid-enhancing factors.

    Full Text Available The Objective of this study was to identify the existence of Campylobacter jejuni based on phenotypic and genotypic characteristic in local chicken and chicken meats. Samples of local chicken intestine and meat were tested for the bacterial existence. Phenotypic examination was carried out by means of cultivation followed by gram staining and biochemical tests. Genotypic examination was conducted by polymerase chain reaction (PCR using genus specific16S rRNA gene at 816 bp and membrane-associated protein A (mapA gene at 589 bp as Campylobacter jejuni species-specific gene. The result of phenotypic detection revealed the existence of Campylobacter spp as gram negative, curved rod shape, oxidase positive, urease negative and motile. Genotypic examination also indicated the existence of bacteria using both primers. However, no Campylobacter jejuni detected from meat of the chickens. The results suggest that the method of PCR using a primer detecting species-specific gene of Campylobacter jejuni gives a rapid and accurate detection of the bacteria as compared to that using phenotypic and biochemical test. Identification of Campylobacter spp from chicken meats should be improved with enrichment method and sample collection.

    Full Text Available Bangladesh is considered one of the most suitable regions for fisheries in the world, with the world's largest flooded wetland and the third largest aquatic biodiversity in Asia after China and India. This paper reviews the performance of fisheries in Bangladesh using data collected from the Bangladesh Department of Fisheries, and related un-published grey literatures. The findings within describe recent growth within Bangladeshi inland fisheries, primarily in the inland aquaculture sector (2014–2015. This increase in the aquaculture production has been made possible with the implementation of scientific and technological modernization. From 2000 and 2016, aquaculture production increased from 712,640 and 2,060,408 metric t, a much larger quantity than wild capture production (1.023 million t in 2016. There has also been a recent increase in the value of fishery exports, with more than US $34.08 billion in 2010 rising to more than US $46.60 billion in 2015. However, fisheries production is well below production targets despite the large gains seen in the aquaculture sector.

    2017-05-01

    The uncertainty in methane (CH4) source strength of rice fields and wetlands is particularly high in South Asia CH4 budgets. We used satellite observations of CH4 column mixing ratios from Atmospheric Infrared Sounder (AIRS), Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY), and Greenhouse Gases Observing Satellite (GOSAT) to estimate the contribution of Bangladesh emissions to atmospheric CH4 concentrations. Using satellite-derived inundation area as a proxy for source area, we developed a simple inverse advection model that estimates average annual CH4 surface fluxes to be 4, 9, and 19 mg CH4 m-2 h-1 in AIRS, SCIAMACHY, and GOSAT, respectively. Despite this variability, our flux estimates varied over a significantly narrower range than reported values for CH4 surface fluxes from a survey of 32 studies reporting ground-based observations between 0 and 260 mg CH4 m-2 h-1. Upscaling our satellite-derived surface flux estimates, we estimated total annual CH4 emissions for Bangladesh to be 1.3 ± 3.2, 1.8 ± 2.0, 3.1 ± 1.6 Tg yr-1, depending on the satellite. Our estimates of total emissions are in line with the median of total emission values for Bangladesh reported in earlier studies.

  18. Key Performance Characteristics of Organic Shrimp Aquaculture in Southwest Bangladesh

    2012-05-01

    Full Text Available In Bangladesh, black tiger shrimp (Penaeus monodon; Fabricius, 1798 aquaculture has come to be one of the most important sectors in both the rural and national economies. Likewise, organic shrimp aquaculture has emerged as an alternative farming enterprise for farmers especially in the southwestern districts of Bangladesh. The present study aims to show key performance characteristics of organic shrimp farmers and farming in a prototypical shrimp farming area in Bangladesh. Data was collected in 2009 from organic shrimp farmers in the Kaligonj and Shyamnagar sub-districts through questionnaire interviews, transect walks and focus group discussions. The mean productivity of organic shrimp farming in the area is 320 kg ha−1 yr−1 (ranging from 120 to 711 kg ha−1year−1. Organic farmers are more likely to have a higher monthly income and less aquaculture experience. Moreover, suitable landholdings and classified labor distribution have been found to play an important role in the development of organic shrimp aquaculture. The most common assets of organic shrimp aquaculture are high yield, low production cost, available post larvae and high market prices. Small business farmers are likely to earn more income benefits from organic shrimp aquaculture than their larger-scale counterparts. Finally, the paper suggests that more research is needed to stimulate the success of organic shrimp aquaculture.

    Each year, approximately 265,000 deaths occur due to burns on a global scale. In Bangladesh, around 173,000 children under 18 sustain a burn injury. Since most epidemiological studies on burn injuries in low and middle-income countries are based on small-scale surveys or hospital records, this study aims to derive burn mortality and morbidity measures and risk factors at a population level in Bangladesh. A household survey was conducted in seven rural sub-districts of Bangladesh in 2013 to assess injury outcomes. Burn injuries were one of the external causes of injury. Epidemiological characteristics and risk factors were described using descriptive as well as univariate and multivariate logistic regression analyses. The overall mortality and morbidity rates were 2 deaths and 528 injuries per 100,000 populations. Females had a higher burn rate. More than 50% of injuries were seen in adults 25 to 64 years of age. Most injuries occurred in the kitchen while preparing food. 88% of all burns occurred due to flame. Children 1 to 4 years of age were four times more likely to sustain burn injuries as compared to infants. Age-targeted interventions, awareness of first aid protocols, and improvement of acute care management would be potential leads to curb death and disability due to burn injuries.

    Diseases caused by mosquito-borne pathogens remain an important source of morbidity and mortality in Bangladesh. To better control the vectors that transmit the agents of disease, and hence the diseases they cause, and to appreciate the diversity of the family Culicidae, it is important to have an up-to-date list of the species present in the country. Original records were collected from a literature review to compile a list of the species recorded in Bangladesh. Records for 123 species were collected, although some species had only a single record. This is an increase of ten species over the most recent complete list, compiled nearly 30 years ago. Collection records of three additional species are included here: Anopheles pseudowillmori, Armigeres malayi and Mimomyia luzonensis. While this work constitutes the most complete list of mosquito species collected in Bangladesh, further work is needed to refine this list and understand the distributions of those species within the country. Improved morphological and molecular methods of identification will allow the refinement of this list in years to come.

    The prevalence of gestational diabetes mellitus (GDM) has important health complications for both mother and child and is increasing all over the world. Although prevalence estimates for GDM are not new in developed and many developing countries, data are lacking for many low-income countries like Bangladesh. To evaluate the prevalence of GDM in Bangladesh. This cross-sectional study included 3447 women who consecutively visited the antenatal clinics with an average gestation age of 26 weeks. GDM was defined according to WHO criteria (fasting plasma glucose [FPG] ≥7.0 mmol/L or 2-h ≥7.8 mmol/L) and the new ADA criteria (FPG ≥5.3 mmol/L or 2-h ≥8.6 mmol/L OGTT). We also calculated overt diabetes as FPG ≥7.0 mmol/L. Prevalence of GDM was 9.7% according to the WHO criteria and 12.9% according to the ADA criteria in this study population. Prevalence of overt diabetes was 1.8%. Women with GDM were older, higher educated, had higher household income, higher parity, parental history of diabetes, and more hypertensive, compared with non-GDM women. This study demonstrates a high prevalence of GDM in Bangladesh. These estimates for GDM may help to formulate new policies to prevent and manage diabetes. Copyright © 2013 Elsevier Ireland Ltd.

  2. Population growth and development: the case of Bangladesh.

    Science.gov (United States)

    Nakibullah, A

    1998-04-01

    In a poor, overly populated country such as Bangladesh, some believe that a high rate of population growth is a cause of poverty which impedes economic development. Population growth would therefore be exogenous to economic development. However, others believe that rapid population growth is a consequence rather than a cause of poverty. Population growth is therefore endogenous to economic development. Findings are presented from an investigation of whether population growth has been exogenous or endogenous with respect to Bangladesh's development process during the past 3 decades. The increase in per capita real gross domestic product (GDP) is used as a measure of development. Data on population, real GDP per capita, and real investment share of GDP are drawn from the Penn World Table prepared by Summers and Heston in 1991. The data are annual and cover the period 1959-90. Analysis of the data indicate that population growth is endogenous to Bangladesh's development process. These findings are reflected both in the Granger causality tests and the decompositions of variances of detrended real GDP per capita and population growth.

    2011-01-01

    In this paper, an attempt is being made to examine the causal relationship between per capita electricity consumption and per capita GDP of Bangladesh using the vector error correction specified Granger causality test to search their short-run, long-run and joint causal relationships for the period of 1971-2008. Empirical findings reveal that there is a short-run unidirectional causal flow running from per capita electricity consumption to per capita GDP without feedback. The presence of a positive short-run causality explains that an increase in electricity consumption directly affects economic activity in Bangladesh. Likewise, results from joint causality exhibit the same as in short-run. By contrast, long-run results show a bi-directional causality running from electricity consumption to economic growth with feedback. These findings can provide essential policy insights to design immediate and long-term growth prospect for Bangladesh keeping in mind its present planned growth strategy and dismal power and energy sector. - Highlights: → Short-run causality running from electricity consumption to economic growth. → Positive SR causality explains electricity generation directly affects economic growth. → For long run, causality runs from electricity consumption to economic growth with feedback. → Joint causality implies the same as in short-run.

    To determine the frequency and magnitude of thrombocytopenia associated with chicken pox in adults. Observational descriptive study. Combined Military Hospital, Attock, from July 2003 to June 2004. All patients of age 15 years and above with history of fever, followed by appearance of the typical vesicular chicken pox rash, were inducted after informed consent. Two milliliters of whole blood was collected on day 1 of admission, and blood counts were performed. Patients were admitted and given 800 mg oral acyclovir, 5 times/day, for 7 days, in addition to symptomatic treatment. Patients were followed till 8 weeks. A total of 410 patients of chicken pox were received, out of which 270 were included. Age of patients ranged between 15 and 40 years with median age of 21 years. Platelet count on the day of admission ranged between 29 x 10(9)/L to 513 x 10(9)/L, mean platelet count 178 x 10(9)/L. Platelet count chicken pox is a common entity. Platelet count remains above 25 x 10(9) /L, which is usually not associated with bleeding manifestations. None of the patients in this series developed purpura. No specific pattern of total leukocyte counts was predictive of the progression or regression in platelet count.

    Cre recombinase has been extensively used for genome engineering in transgenic mice yet its use in other species has been more limited. Here we describe the generation of transgenic chickens expressing Cre recombinase. Green fluorescent protein (GFP)-positive chicken primordial germ cells were stably transfected with β-actin-Cre-recombinase using phiC31 integrase and transgenic chickens were generated. Cre recombinase activity was verified by mating Cre birds to birds carrying a floxed transgene. Floxed sequences were only excised in offspring from roosters that inherited the Cre recombinase but were excised in all offspring from hens carrying the Cre recombinase irrespective of the presence of the Cre transgene. The Cre recombinase transgenic birds were healthy and reproductively normal. The Cre and GFP genes in two of the lines were closely linked whereas the genes segregated independently in a third line. These founders allowed development of GFP-expressing and non-GFP-expressing Cre recombinase lines. These lines of birds create a myriad of opportunities to study developmentally-regulated and tissue-specific expression of transgenes in chickens.

    The chicken Major Histocompatibility Complex (MHC) is very strongly associated with disease resistance and thus is a very important region of the chicken genome. Historically, MHC (B locus) has been identified by the use of serology with haplotype specific alloantisera. These antisera can be difficult to produce and frequently cross-react with multiple haplotypes and hence their application is generally limited to inbred and MHC-defined lines. As a consequence, very little information about MHC variability in heritage chicken breeds is available. DNA-based methods are now available for examining MHC variability in these previously uncharacterized populations. A high density SNP panel consisting of 101 SNP that span a 230,000 bp region of the chicken MHC was used to examine MHC variability in 17 heritage populations of chickens from five universities from Canada and the United States. The breeds included 6 heritage broiler lines, 3 Barred Plymouth Rock, 2 New Hampshire and one each of Rhode Island Red, Light Sussex, White Leghorn, Dark Brown Leghorn, and 2 synthetic lines. These heritage breeds contained from one to 11 haplotypes per line. A total of 52 unique MHC haplotypes were found with only 10 of them identical to serologically defined haplotypes. Furthermore, nine MHC recombinants with their respective parental haplotypes were identified. This survey confirms the value of these non-commercially utilized lines in maintaining genetic diversity. The identification of multiple MHC haplotypes and novel MHC recombinants indicates that diversity is being generated and maintained within these heritage populations. © 2016 Poultry Science Association Inc.

    Aseel is an important native chicken breed of India, known for its martial qualities (aggressive fighting abilities), pugnacity, and majestic gait. The aim of the study is to conserve and characterize the Aseel germplasm, which is considered to be endangered. The birds were maintained on deep litter under a simulated backyard type of housing having night shelter and a free-range area. A total of 313 chicks produced in the second generation from the flock collected from native tract in Andhra Pradesh was characterized for morphological, growth, production, and meat quality parameters. Aseel birds were characterized by multicolored plumage (predominantly dark brown, black, golden, etc.) with solid feather patterns and normal distribution. Ear lobes were red (92%) and small in size, while 98% of the birds had red colored pea combs with variations in intensity of color. The shank color was yellow in the majority (65%) of the birds. The skin color was white (98%) with pinkish red coloration on exposed body parts, especially on the breast. The fertility and hatchability on total eggs were 67.2 and 41.4%, respectively. Cocks were heavier (P ≤ 0.05) with distinct sexual dimorphism in Aseel. The body weight of hens and cocks was 1,704.4 ± 23.2 and 2,702.5 ± 28.1 g at 40 wk and 2,333.7 ± 26.1 and 3,793.7 ± 20.8 g at 72 wk of age, respectively. The age at sexual maturity was 214.0 ± 6.0 days. The egg production up to 40, 52, and 64 wk of age was 18.0 ± 1, 30.0 ± 2.0, and 47 ± 3 eggs, respectively. The annual egg production (72 wk) was 64 ± 6 eggs. The proximate composition of breast muscle was; protein 21.5 ± 0.5%, fat 3.4 ± 0.1%, ash 2.0 ± 0.1%, and moisture 73.3 ± 0.5%. The pH of breast muscle was 6.0 ± 0.03 and the cholesterol content was 72.5 ± 6.7 mg/100 g. Efforts are on for improving the productivity in the flock without compromising the original breed characteristics. © 2017 Poultry Science Association Inc.

    Shahidullah, Kazi K.

    This dissertation reports lower secondary science teachers perceptions of current practice in Dhaka, Bangladesh concerning inquiry and STEM Education in order to establish a baseline of data for reform of science education in Bangladesh. Bangladesh has been trying to incorporate inquiry-based science curricula since the 1970s. Over time, the science curricula also aligned with different international science education movements such as Science for All, Scientific Literacy, Science, Technology, and Society. Science, Technology, Engineering, and Mathematics (STEM) is the most recent science education movement in international science education. This study explored current practices and perceptions of lower secondary science teachers in order to establish a baseline of current practice so that future reform recommendations may be pursued and recommendations made for Bangladesh to overcome the inquiry-based challenges and to incorporate new STEM-based science education trends happening in the US and throughout the world. The study explored science teachers perceptions and readiness to transform their science classrooms based on self-reported survey. The survey utilized Likert-type scale with range 1 (very strongly disagree) to 6 (very strongly agree) among four hundred lower secondary science teachers, teacher training college faculty, and university faculty. The data is presented in four different categories: curriculum, instruction, assessment, and professional development. Results indicated that the participants understand and practice a certain level of inquiry in their science classrooms, though they do not have adequate professional development. Participants also stated that they do not have sufficient instructional materials and the curriculum is not articulated enough to support inquiry. On the other hand, the participants reported that they understand and practice a certain degree of inquiry and STEM-based science education, but they also state that the

    Melioidosis, caused by Burkholderia pseudomallei, is an endemic disease in Bangladesh. No systematic study has yet been done to detect the environmental source of the organism and its true extent in Bangladesh. The present study attempted to isolate B. pseudomallei in soil samples and to determine its seroprevalence in several districts in Bangladesh. Soil samples were collected from rural areas of four districts of Bangladesh from where culture confirmed melioidosis cases were detected earlier. Multiple soil samples, collected from 5-7 sampling points of 3-5 sites of each district, were cultured in Ashdown selective media. Suspected colonies of B. pseudomallei were identified by biochemical and serological test, and by polymerase chain reaction (PCR) using 16s rRNA specific primers. Blood samples were collected from 940 healthy individuals of four districts to determine anti- B. pseudomallei IgG antibody levels by indirect enzyme linked immunosorbent assay (ELISA) using sonicated crude antigen. Out of 179 soil samples, B. pseudomallei was isolated from two samples of Gazipur district which is located 58 km north of capital Dhaka city. Both the isolates were phenotypically identical, arabinose negative and showed specific 550bp band in PCR. Out of 940 blood samples, anti- B. pseudomallei IgG antibody, higher than the cut-off value (>0.8), was detected in 21.5% individuals. Seropositivity rate was 22.6%-30.8% in three districts from where melioidosis cases were detected earlier, compared to 9.8% in a district where no melioidosis case was either detected or reported (p 50 years respectively. The seropositivity rates were 26.0% and 20.6% in male and female respectively, while it was 20-27% among different occupational groups. No significant association was observed with gender (χ2 = 3.441, p = 0.064) or any occupational group (χ2 = 3.835, p = 0.280). This is the first study demonstrating the presence of B. pseudomallei in the environmental (soil) samples of
