    This article compares public and community schools in Salvador, the state capital of Bahia, Brazil. Based on quantitative data analysis and qualitative research conducted on-site during three research trips in 2001, 2003 and 2005, the author finds that Brazil's extreme inequality and the associated concentration of state power in a few hands stand in the way of an effective reform. In 1999, the state of Bahia started to reform its basic education cycle, but the author's research shows that Bahian elites use access to basic education to defend their inherited privilege. The analysis of community schools further demonstrates that inequality also blocks effective community and parental involvement in school management, as schools tend to distance themselves from neighbourhoods portrayed as poor and black, and thus "dangerous".

    Full Text Available In this paper, I seek to assess the role of the media in ongoing subnational democratization processes from a State-in-society perspective. I use the case of Bahia, a state in North-Eastern Brazil, to assess ownership and social access to the media, the media’s autonomy from both the State and social actors as well as how conflicts between public interest and private profit are solved. We will thus understand the role of subnational media in sustaining pluralism and in providing independent sources of information, two critical dimensions of democracy.

    A total of 117 species of freshwater decapod crustaceans are known from Brazil. Knowledge regarding the fauna of Decapoda from inland waters in the state of Bahia, northeast Brazil, is incipient. In spite of its wide territory and rich hydrographic net, only 13 species of limnetic decapods have been reported from that state. The objective of this contribution was to survey decapod crustaceans of some hydrographic basins in southeastern Bahia. The material described herein was obtained in samplings conducted between 1997 and 2005. Voucher specimens were deposited in the carcinological collections of the Museu de Zoologia, Universidade Estadual de Santa Cruz, Ilhéus, Brazil, and Departamento de Oceanografia, Universidade Federal de Pernambuco, Recife, Brazil. A total of 13 species was collected. The carideans were represented by the atyids Atya scabra (Leach, 1815) and Potimirim potimirim (Müller, 1881) and the palaemonids Macrobrachium acanthurus (Wiegmann, 1836), M. amazonicum (Heller, 1862), M. carcinus (Linnaeus, 1758), M. heterochirus (Wiegmann, 1836), M. jelskii (Miers, 1877), M. olfersi (Wiegmann, 1836), and Palaemon (Palaemon) pandaliformis (Stimpson, 1871). The brachyurans were represented by the portunids Callinectes bocourti A. Milne-Edwards, 1879 and C. sapidus Rathbun, 1895, the trichodactylid Trichodactylus fluviatilis Latreille, 1828 and the panopeid Panopeus rugosus A. Milne-Edwards, 1881. Macrobrachium heterochirus represents a new record from Bahia, and M. amazonicum is reported for the first time in southeast Bahia. The occurrence of two extreme different forms of T. fluviatilis was observed. Form A is characterized by the frontal margin of carapace bordered by conspicuous granules, the anterolateral margin provided with developed teeth plus granules, and the posterolateral margin provided with granulation similar to that found on the front. In form B the frontal margin is smooth or has an inconspicuous granulation; the anterolateral margin is

    This work is a retrospective study of latrodectism in the State of Bahia, Brazil, from August 1980 to July 1990. The data concerning the accidents were obtained from file cards at the Antivenom Information Center of Bahia (AVICB). Latrodectus curacavienis was the ethiologic agent identified in 28% of the arachnid accidents. The major incidence was registered in urban area (57%) affecting men (70%) more than women, with 10 to 29 year-old age group (58%). Local pain (56%), erythematous papula (29%) and light oedema (17%) were the principal local symptoms. Pain in the limbs (29%), tremor and rigidities (29%), sweating (28%), limbs and arms paresthesia (21%) and abdominal pain (17%) were systemic ones. The treatment was mainly symptomatic (67%) and antivenin serum was used in 21% of the cases. After serotherapy, 64% of the patients left the hospital within less than 24 hours.

    Full Text Available A new species of pulmonate snail was recently collected in a small forest fragment in the city of Bom Jesus da Lapa, Bahia state, Brazil. Bahia is known for a high diversity of land snails and Bom Jesus da Lapa is an interesting locality, since it is close to the interface between two major Brazilian biomes: Cerrado and Caatinga. The new species is described as Cyclodontina tapuia sp. nov. and can be easily identified by its brown shell, conical spire, convex whorls, a sculpture comprised of strong ribs, and an aperture with four barriers: a median parietal tooth, a median palatal tooth, a median basal tooth and a strong columellar lamella. This discovery is also a reminder of how little the Brazilian continental molluscan fauna is known and of the urgency in studying and preserving the rich (though usually overlooked fauna of the Caatinga.

    This work presents results of the Joint Project for Solar UV Index Measurements in Southern Bahia State (PIU Project), and represents the first effort to measure UV radiation in this tourist region. The project goal is twofold: it has a scientific component in which the distribution of UV Index will be mapped out, and it also intends to disseminate the data as a mean of divulgation of the UV Index levels to the population. This constitutes a meaningful effort to reduce health risks from excessive solar radiation exposure in a country that reports more than 120,000 new skin cancer cases each year. This project is within the framework of a larger initiative to studying UV index distribution in Brazilian regions. PIU project has had two phases: 1) seasonal measurements were performed during the summer and winter seasons of 2006 and 2007 on a sandy beach in Ilhéus (15,0° S; 39,0° W; sea level), as well as on an asphalt surface in the urban perimeter of Itabuna (14,8° S; 39,3° W; 54 m ASL); and 2) since October 2007, measurements have been continuously conducted on a concrete surface, about 20 km from the beach, in a urban area of Ilhéus. During the summer season, UV Index reaches extreme values (>11), and in winter, results range between high (6

    Full Text Available Brazil was the country that received the largest number of Africans during the time of colonization, and Bahia was the Brazilian state that received the largest number of slaves from Africa. The purpose of this study was to evaluate the coverage of the newborn screening program for sickle cell disease in the Recôncavo Baiano region of the state of Bahia, and to show the frequency of the subjects with hemoglobin variants in the 2006–2009 period. Blood samples from neonates in twelve cities in the Recôncavo Baiano region were analyzed by High Performance Liquid Chromatography. A total of 16,402 children were born in this period, 14,773 of which underwent newborn screening. In this period 1416 children were born carrying hemoglobin variants HbS and HbC. Forty-seven patients—20 HbSS genotype and 27 HbSC genotype—were diagnosed in eleven of the twelve cities surveyed. The proportion of children born with sickle cell disease in the Recôncavo Baiano region was 1/314, which was higher than the 1/650 rate for the state of Bahia. The data presented in this study confirm the high frequency of sickle cell disease in Recôncavo Baiano, demonstrating the need to create a referral center for the care of patients with sickle cell diseases in the region.

    The Cultural Heritage disappears at a rate higher than we are able, not only, to restore but also to document: human and natural factors, negligence or worst, deliberate demolitions put in danger the collective Architectural Heritage (AH). According to CIPA statements, the recording is important and has to follow some guidelines. The Architectural and Urban Heritage data have to be historically related, critically assessed and analyzed, before to be organized according to a thematic structure and become available for further uses. This paper shows the experiences developed by the Laboratory of Computer Graphics applied to Architecture and Design (LCAD), at the Architecture School of the Federal University of Bahia (FAUFBA), Brazil, in cooperation with the Università Politecnica delle Marche (UNIVPM, DICEA Department), Italy, in documenting architectural heritage. The research set up now has been carried out in the historical sites of Bahia, as Pelourinho neighborhood, a World Heritage by UNESCO. Other historical sites are in the plan of this survey, like the cities of Lençóis and Mucugê in Chapada Diamantina region. The aim is to build a technological platform based on low cost digital technologies and open source tools, such as Panoramic Spherical Photogrammetry, Spatial Database, Geographic Information Systems, Three-dimensional Geometric Modeling, CAD technology, for the collection, validation and dissemination of AH.

    Hemoglobinopathies are hereditary disorders of the hemoglobin molecule with a high prevalence worldwide. Brazil has a prevalence of 0.1 to 0.3% of newborns with sickle cell anemia and 20.0 to 25.0% of heterozygous alpha2 thalassemia among African Brazilians. In the present study, we investigated the presence of variant hemoglobins and alpha2(3.7 Kb) and alpha2 (4.2 Kb) thalassemia in newborns from Salvador, Bahia, Brazil. Samples of umbilical cord blood from a total of 590 newborns were analyzed, of which 57 (9.8%) were FAS; 36 (6.5%) FAC; one (0.2%) SF; and five (0.9%) FSC. One hundred fourteen (22.2%) newborns had alpha2(3.7 Kb) thalassemia, of whom 101 (19.7%) were heterozygous and 13 (2.5%) homozygous, showing statistical significance for hematological data between newborns with normal alpha genes and alpha2(3.7 Kb) thalassemia carriers. The alpha2(4.2 Kb) thalassemia was not found. Frequencies found in the present study confirm that hemoglobinopathies are a public health problem in Brazil, emphasizing the need for neonatal screening and genetic counseling programs.

    2017-08-17

    This study reports the pathogen Perkinsus beihaiensis in oysters of the genus Crassostrea on the coast of the State of Bahia (Brazil), its prevalence, infection intensity and correlation with salinity. Oysters (n = 240) were collected between October and December 2014 at eight sampling stations between latitudes 13°55'S and 15°42'S. The laboratory procedures included macroscopic analysis, histology, culture in Ray's fluid thioglycollate medium (RFTM), Polymerase Chain Reaction (PCR) and DNA sequencing. PCR and sequencing have been used for the genetic identification of oysters as well. Two species of oysters have been identified: Crassostrea rhizophorae and C. brasiliana. In both oyster species P. beihaiensis was the only Perkinsus species detected. In C. rhizophorae, the average prevalence was 82.8% by histology and 65.2% by RFTM. In C. brasiliana, the prevalences were 70.5% and 35.7%, respectively. The higher prevalence of P. beihaiensis in C. rhizophorae was probably influenced by salinity, with which was positively correlated (r> 0.8). In both oysters, P. beihaiensis was located mainly in the gastric epithelium. The infection was generally mild or moderate, without apparent harm to the hosts, but in cases of severe infection, there was hemocytical reaction and tissue disorganization. The generally high prevalence in the region suggests that oysters should be monitored with respect to this pathogen, especially in growing areas.

    Full Text Available ABSTRACT OBJECTIVE To identify the spatial distribution patterns and areas of higher risk of preventable perinatal mortality in the city of Salvador, State of Bahia, Brazil. METHODS We carried out a spatial aggregated study in 2007, considering the weighting areas (census tracts contiguous sets of Salvador, of which the center and north present low life conditions. Data were obtained from national vital statistics systems and the 2010 Census. Addresses of live births and stillbirths were geocoded by weighting area. The spatial distribution of the perinatal mortality rate was analyzed from thematic maps. Spatial dependence was evaluated by the Global and Local Geary’s and Moran’s Indexes. RESULTS Crude and smoothed perinatal mortality rates were high in areas situated to the north, west, and in center of Salvador. The smoothed rates in weighting areas ranged from 4.9/1,000 to 22.3/1,000 births. Of all perinatal deaths, 92.1% could have been prevented. We identified spatial dependence for preventable perinatal mortality for care in pregnancy, with neighboring areas with high risk in the north of the city. CONCLUSIONS The preventability potential of perinatal mortality was high in Salvador, in 2007. The spatial distribution pattern with higher rates in disadvantaged areas of the city suggests the existence of social inequalities in health. The characteristics of the process of urban development of Salvador, which has inadequate prenatal care, possibly influenced the magnitude and spatial distribution pattern of this mortality.

    Chikungunya is an emerging arbovirus that is characterized into four lineages. One of these, the Asian genotype, has spread rapidly in the Americas after its introduction in the Saint Martin island in October 2013. Unexpectedly, a new lineage, the East-Central-South African genotype, was introduced from Angola in the end of May 2014 in Feira de Santana (FSA), the second largest city in Bahia state, Brazil, where over 5,500 cases have now been reported. Number weekly cases of clinically confirmed CHIKV in FSA were analysed alongside with urban district of residence of CHIKV cases reported between June 2014 and October collected from the municipality's surveillance network. The number of cases per week from June 2014 until September 2015 reveals two distinct transmission waves. The first wave ignited in June and transmission ceased by December 2014. However, a second transmission wave started in January and peaked in May 2015, 8 months after the first wave peak, and this time in phase with Dengue virus and Zika virus transmission, which ceased when minimum temperature dropped to approximately 15°C. We find that shorter travelling times from the district where the outbreak first emerged to other urban districts of FSA were strongly associated with incidence in each district in 2014 (R(2)).

    1985-07-01

    The possibility that diamictites of the Late Precambrian Bebedouro Formation of northern Bahia, Brazil, are glacial in origin has been based on the areal extent, diversity of the lithology of the stones and the presence of outsize dropstones in rhythmites. More detailed studies on the diamictites show that some of the stones are faceted and their shapes are typical of those developed by glacial transport. Additionally, a small abraded pavement is described and garnets found in the matrix of the diamictite have chattermark trails. Taken in aggregrate, these observations suggest a glacial origin for the Bebedouro Formation. In the study area, the texture of the diamictites range from stone-rich to siltstones containing sporadic stones. The stone-rich diamictites are commonly found in layers, up to a metre in thickness, separated by poorly laminated siltstone. The Formation probably was deposited in a large lake or sea and the layered diamictites are debris flows which were derived from uneven piles of glacial debris deposited on the floor of the lake or sea.

    Abstract Information about the snake diversity and their natural history from the Atlantic forest domain in Brazil refer mostly to inland forests than to coastal region. Within the state of Bahia, this knowledge is concentrated to the southeastern coastal stretch. Herein we report on the diversity of snakes from the restinga, ombrophilous forest and anthropogenic environment from the northern Atlantic coast of Bahia. We sampled nine sites for three years and visited four museum collections. Furthermore, we provide anecdotal natural history information, voucher analyses, literature complements, and a key to fascilitate species identification. We report a total of 774 snakes belonging to 50 species and 23 new distribution records for northeastern coast of Bahia, supplemented by new data on feeding and reproduction. The number of detected species is similar to numbers obtained in comparable studies from other Brazilian ecoregions. This study reports and focuses for the first time on all known species of snakes from the northeastern coast of Bahia. PMID:27594800

A total of 1 802 fishes belonging to 23 families and 54 species were observed. The most abundant species were the pomacentrids Stegastes fuscus and Abudefduf saxatilis. No significant differences were found for species richness or density of conspicuous species, but density of small cryptic species was low on reefs with high bottom rugosity, where there were more holes and crevices available. Herbivores were dominant on AR, AL and RF, invertivores on AL and both groups were dominant on IT. Some habitat variables such as rugosity and benthic cover were strongly correlated to species and sites. High bottom heterogeneity was found among reefs but they still presented similar species composition, richness and density. Within small-scale studies, such similarities in composition and richness are to be expected for reef fish communities, as most of the species concerned have a wide distribution range.Este trabalho descreve pela primeira vez as comunidades de peixes em cinco recifes rasos de Santa Cruz de Cabrália e Porto Seguro (Araripe-AR, Itacipanema-IT, Alagados-AL, Naufrágio-NA e Recife de Fora Marine Park-RF, sul da Bahia, nordeste do Brasil.

    There are 176 species representing eight genera and two families of Plecoptera known from Brazil. However, only ten of these species are recorded from the State of Bahia. In this study, an inventory of stoneflies from the southern region of Bahia State, Serra Bonita, including the municipality of Camacan, was undertaken from 2007-2012. Stoneflies were collected using UV light pan traps, Malaise traps, and aerial nets. One new gripopterygid species, Tupiperla bispoi n. sp., is described and illustrated. Four genera representing ten other species are recorded: Gripopteryx cancellata, G. clemira, G. garbei, G. pinima, Paragripopteryx sp., and Tupiperla tessellata (Gripopterygidae), Kempnyia alterosarum, K. gracilenta, K. jatim, and K. neotropica (Perlidae). With the present study, the number of known species of stoneflies recorded from Bahia State is 17, ten of these recorded from the Serra Bonita region.

    To assess mortality trend due to heart failure (HF) in Salvador--Bahia, from 1979 to 1995. HF was defined by notations from the 9th Review of International Disease Code (IDC9) 428.0, 428.1 and 428.9. HF death and population data (metropolitan area of Salvador) were obtained by means of Secretaria de Saúde da Bahia (Bahia State Health Secretariat) and Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics). Mortality rates (/100,000) were total or per gender and age, and gross or adapted per age (straight standardization). Mortality rates due to HF had a progressive reduction in the period of time assessed, for both genders, especially up to 1992. From then and up to 1995, there was an apparent stabilization of the curves. Gross mortality rate went from 25.0/10(5), in 1979, to 16.4/10(5) inhabitants, in 1995 (a decrease of 34.4%). The reduction was 34.0% (23.3/10(5), in 1979, to 15.4/10(5) inhabitants, in 1995) for male sex and 35.2% (26.7/10(5), in 1979, to 17.3/10(5) inhabitants, in 1995), for female sex. The same trend took place in several age ranges, including the population > or = 40 years old, which has a greater risk for HF. After adaptation per age (standard population of 1979), it is observed that relative reductions in the rates were even greater. Mortality due to HF, in Salvador-Bahia, decreased from 1979 to 1992, becoming stable from then to 1995.

    Full Text Available Monitoring of the morphodynamic variations of the beaches associated with an estuary contiguous with Garcez Point, Bahia, Brazil, and the superposition of aerial photographs from the region, show the presence of distinctive erosive and constructive cycles of low and high frequencies. Between 1959 and 1989, one event of shoreline erosion and progradation was recognized on the oceanic beaches just outside the estuary. Inside the estuary, an erosion phase at the southern margin coincides with a constructive phase at the other side, and vice-versa. On the southern estuarine beach, low-frequency cycles of erosion and progradation are also perceived, but with the inverse trend when compared to the contiguous oceanic beach. During the beach monitoring period (February/1991 to July/1992, the oceanic beach showed retreat rates varying from 23.7m/year, at the channel entrance, to 1.0m/year, three kilometers away from it. During the same period, the estuarine beach advanced at a rate of 60.3m/year. The long-term dynamics of the shoreline position in both sides of the estuarine entrance appears to be related to the position of the channel in the ebb-tidal delta.O monitoramento das variações morfodinâmicas das praias associadas com um estuário contíguo à Ponta dos Garvez, Bahia, Brasil, e a superposição de fotos aéreas da região, mostram a presença de distintos ciclos erosivos e construtivos, de baixa e alta freqüências. Entre 1959 e 1989, um evento de erosão e progradação da linha de costa foi reconhecido nas praias oceânicas fora do estuário. Dentro do estuário, uma fase erosiva na margem sul, coincide com uma fase construtiva no outro lado, e vice-versa. Na margem estuarina sul, são também percebidos ciclos de erosão e progradação de baixa freqüência, porém com um sentido inverso quando comparados aos da praia oceânica contígua.

    Full Text Available Séries históricas de precipitação pluvial de 19 estações pluviográficas localizadas no Estado da Bahia e operadas pela Agência Nacional de Energia Elétrica (ANEEL, foram analisadas, objetivando-se ajustar modelos teóricos de distribuição de probabilidade aos dados de chuvas intensas e estabelecer a relação entre intensidade, duração e freqüência da precipitação pluvial. Para cada estação pluviográfica determinaram-se as séries de intensidade máxima anual das precipitações com durações de 10, 20, 30, 40, 50, 60, 120, 180, 240, 360, 720 e 1.440 min. Os modelos probabilísticos testados foram os de Gumbel, Log-Normal a dois e três parâmetros, Pearson e Log-Pearson III. As equações de intensidade-duração-freqüência da precipitação pluvial foram ajustadas utilizando-se o método de regressão não-linear de Gauss-Newton. O teste de aderência de Kolmogorov-Smirnov, utilizado para a verificação do ajuste dos modelos aos dados de chuvas intensas, evidenciou que o modelo de Gumbel foi o que melhor se ajustou para a maior parte das combinações entre estações pluviográficas e durações estudadas. Foram evidenciadas, para uma mesma duração, grandes variações nas intensidades de precipitação entre as estações estudadas.This study was conducted for fitting probabilistic models to data of rain storms.

    Full Text Available Using the average directions of the main wave-fronts which approach the coast of Bahia State - coinciding with that of the main wind occurring in the area - and of their periods, we define a wave climate model based on the construction of refraction diagrams. The resulting model of sediment transport was able to reproduce, in a general way, the sediment dispersion patterns furnished by geomorphic indicators of the littoral drift. These dispersion patterns control the generation of different types of sediment accumulations and of coastal stretches under erosion. We demonstrate that the presence of the Abrolhos and Corumbaú Point coral reefs is an important factor controlling the sediment dispersion patterns, since them act as a large protection against the waves action.

    Full Text Available Cacao was introduced in Bahia in 1756, becoming later the largest producer state in the country. In order to supportthe planting of cacao in the region, a breeding program was established by CEPEC at the beginning of the 1970s. For a long time,the program consisted in testing new hybrids (full-sibs and releasing a mixture of the best ones to farmers. Lately, particularly afterthe witches´ broom arrival in the region, in 1989, recurrent breeding strategies were implemented, aiming mainly the developmentof clones. From 1993 to 2010, more than 500 progenies, accumulating 30 thousand trees, were developed by crossing many parentswith resistance to witches´ broom, high yield and other traits. In this period, more than 500 clones were put in trials and 39 clonesand 3 hybrids were released to farmers. In this paper the strategies and results achieved by the program are reviewed. Overall theprogram has good interface with pathology and genomic programs.

    The cultivation of tropical fruit trees has grown considerably in the state of Bahia, northeastern Brazil. Some of these have been severely attacked by phytophagous mites, which are usually controlled by the use of chemical pesticides. However, there is today a growing interest for the adoption of less aggressive measures of pest control, as for example the use of predatory mites. Most of the plant-inhabiting predatory mites belong to the family Phytoseiidae. The objective of this paper is to report the phytoseiid species found in an intensive survey conducted on cultivated tropical fruit trees in fifteen localities of the southern coast of Bahia. Measurements of relevant morphological characters are provided for each species, to complement the understanding of the morphological variation of these species. Twenty-nine species of sixteen genera were identified. A key was elaborated to assist in the separation of these species. Fifteen species are reported for the first time in the state, raising to sixty-six the number of species of this family now known from Bahia. Seventy-two percent of the species collected belong to Amblyseiinae, followed by Typhlodrominae (21%) and Phytoseiinae (7%). The most diverse genus was Amblyseius. Amblyseius operculatus De Leon was the most frequent and abundant species. Studies should be conducted to evaluate the possible role of the most common predators as control agents of the phytophagous mites co-occurring with them.

    Full Text Available The aim of this study in Curaça, Bahia, Northeast Brazil was to explore possible factors associated with the infestation of human dwellings by Triatoma brasiliensis or Triatoma pseudomaculata, two sylvatic triatomine species. We use multiple logistic regression analysis to show how structural features of the peridomiciliary area combine with the number of animals and sociological factors to allow infestation of some dwellings. It is suggested that T. brasiliensis is associated with human activities, while T. pseudomaculata is associated with vegetation and animals. Peridomiciliary farm animals are a strong risk factor for triatomine infestation.

    This study investigated the occurrence of the protozoan Perkinsus in the oyster Crassostrea rhizophorae on the coast of Bahia State, Brazil. The oysters (n = 900) were collected in February-March and July-August 2010. The Ray's fluid thioglycollate medium (RFTM) analysis of gills and rectum revealed hypnospores of Perkinsus sp. with a high mean prevalence (63%). The infection intensity varied from very light to advanced. The polymerase chain reaction confirmed Perkinsus in 87.2% of the RFTM-positive oysters. Histological analysis showed trophozoites and schizonts phagocytized by hemocytes, mainly in the intestine and the stomach epithelium. Copyright © 2012 Elsevier Inc. All rights reserved.

    Rios, Polianna Alves Andrade; Mota, Eduardo Luiz Andrade

    2013-01-01

    This study describes the temporal evolution of mortality due to traffic accidents in regions within Bahia State, Brazil, from 1996 to 2007, using data from the Brazilian Mortality Information System. We calculated overall rates of mortality due to traffic accidents and specific rates by type of victim. Temporal evolution was analyzed by means of correlations between rates and years of study, as well as polynomial regression models to evaluate trends. During the study period, the regions analyzed accounted for 60% of deaths due to traffic accidents in Bahia. Excess mortality among males and superior percentage of deaths in young individuals were observed. Overall, the evolution of global rates showed decreases beginning in 1998, but growth resumption in 2000, although the trend was not statistically significant. Regional differences were more marked when analyzing rates according to type of victim. However, a growing trend was observed in most locations for rates of accidents involving motorcyclists, which, in conjunction with other findings, substantiates concerns regarding the current situation of increased deaths involving motorcycles in Brazil.

    Full Text Available This study presents the first taxonomic inventory of the order Zygnematales in the Litoral Norte Environmentally Protected Area, in the state of Bahia, Brazil. Fifty samples of planktonic and periphytic material were collected, from lotic and lentic environments, during the summer (January-March and winter (June-August of 2009. We identified 18 taxa distributed among five genera (Cylindrocystis, Mougeotia, Netrium, Spirogyra, and Spirotaenia. Of those 18 taxa, eight were new additions to the Brazilian desmid flora: Mougeotia calcarea; Mougeotia elegantula; Spirogyra gracilis; Cylindrocystis crassa var. elliptica; Cylindrocystis brebissonii var. minor; Cylindrocystis brebissonii var. turgida; Netrium digitus var. parvum; and Netrium oblongum var. oblongum. The geographical distributions of ten taxa were extended to include northeastern Brazil.

    Full Text Available This article represents the first ethnospongiological study in Brazil, and it aimed at recording artisanal fishermen’s knowledge about sea sponges and their ecological interactions. The study was carried out in the Ilha do Contrato community at Camamu Bay, Bahia State, Brazil. The data were obtained by means of open-ended interviews and projective tests, and followed the usual techniques of ethnographic surveys. The interviewees had knowledge regarding ecological interactions among fish, sea sponges and sponge endofaunal composition. According to the results, there is some congruence between folk wisdom and scientific knowledge. The importance of integrating local knowledge into management and conservation plans designed for the Camamu Bay region, as well as the set of data on ecology of reef communities, should be considered.

    wetlands. The disease is characterized mainly by granulomatous lesions in the hosts. The purpose of this study was to report the occurrence of pythiosis in sheep in the states of Pernambuco (PE and Bahia (BA, Northeastern Brazil, as well as to evaluate the efficacy of an immunotherapic against ovine pythiosis. Blood samples were collected from 53 sheep, 49 from flocks in counties located in PE and four from BA. Seven sheep showed clinical signs of ovine pythiosis; one of them was submitted to euthanasia and its head and submandibular lymph node was collected and sent for histopathologic and mycological analyses. Other six sheep were treated with an immunotherapic. During the treatment the animals were kept in the Sheep Industry Sector facilities at Univasf/Petrolina-PE. ELISA, fungal culture and polymerase chain reaction (PCR methods were used to confirm the diagnosis of clinical ovine pythiosis in the sheep flock. At microscopic examination of the material collected from the nasal cavity of a sheep euthanized was observed a focally extensive area of necrosis with presence of diffuse infiltration of intact and degenerated neutrophils bordering the cartilage. Only one sheep showed clinical cure, indicating efficiency in the pythiosis treatment of 16.7% (1/6. Ovine pythiosis has been increasing in several municipalities of PE and BA. In this context, the immunotherapy may be an alternative to be searched. Therefore, further studies are needed to investigate the effect of immunotherapy on ovine pythiosis.

    In Brazil, and mainly in the State of Bahia, crude vegetable oils are widely used in the preparation of food. Street stalls, restaurants and canteens make a great use of palm oil and soybean oil. There is also some use of castor oil, which is widely cultivated in the Sertão Region (within the State of Bahia), and widely applied in industry. This massive use in food preparation leads to a huge amount of waste oil of different types, which needs either to be properly disposed of, or recovered. At the Laboratorio Energia e Gas-LEN (Energy & Gas lab.) of the Universidade Federal da Bahia, a cycle of experiments were carried out to evaluate the recovery of waste oils for biodiesel production. The experiences were carried out on a laboratory scale and, in a semi-industrial pilot plant using waste oils of different qualities. In the transesterification process, applied waste vegetable oils were reacted with methanol with the support of a basic catalyst, such as NaOH or KOH. The conversion rate settled at between 81% and 85% (in weight). The most suitable molar ratio of waste oils to alcohol was 1:6, and the amount of catalyst required was 0.5% (of the weight of the incoming oil), in the case of NaOH, and 1%, in case of KOH. The quality of the biodiesel produced was tested to determine the final product quality. The parameters analyzed were the acid value, kinematic viscosity, monoglycerides, diglycerides, triglycerides, free glycerine, total glycerine, clearness; the conversion yield of the process was also evaluated.

    Full Text Available This study provides an analysis of the occurrence and the spatial and temporal distribution of marine turtle strandings found in the south of the State of Bahia. Data was collected between January 2006 and June 2008. This study covers an area of 220 km of the southern coast of Bahia State (northeastern Brazil, and spatial analyses were made considering data collected in three bases suported by Petrobras-Petróleo Brasileiro S/A distributed in the area. The records were sorted according to month and year, species, age group and sex. A total of 260 stranding were reported: 183 of Chelonia mydas (74.1%, the most frequent species. The highest number of strandings was recorded in Gamboa do Morro Base. Juveniles presented the highest densities, but no differences between adults and small juveniles were detected. Males were more frequently stranded in Gamboa do Morro Base, while females were more frequent in Ilhéus Base. An increase in the number of stranding between 2006 and 2008 was noted; moreover, the months with more records were January, February, March, October and December. The number of stranding events was discontinuously distributed in the study area. This study also demonstrated the usefulness of implement different strategies of recording marine turtle strandings: direct monitoring efforts (patrol in remote beaches and educational campaigns applied on beaches frequented by tourists. This study demonstrated that, despite spatial nearby, the three bases attend independent biological systems and show different stranding dynamics, thus different conservancy actions should be implemented in order to improve the knowledge on natural history of sea-turtles in the southern coast of Bahia State.

  20. The dynamics of dengue virus serotype 3 introduction and dispersion in the state of Bahia, Brazil

    Directory of Open Access Journals (Sweden)

    Paulo Roberto Santana de Melo

    2007-12-01

    Full Text Available By 2002, dengue virus serotype 1 (DENV-1 and DENV-2 had circulated for more than a decade in Brazil. In 2002, the introduction of DENV-3 in the state of Bahia produced a massive epidemic and the first cases of dengue hemorrhagic fever. Based on the standardized frequency, timing and location of viral isolations by the state's Central Laboratory, DENV-3 probably entered Bahia through its capital, Salvador, and then rapidly disseminated to other cities, following the main roads. A linear regression model that included traffic flow, distance from the capital and DENV-1 circulation (r² = 0.24, p = 0.001 supported this hypothesis. This pattern was not seen for serotypes already in circulation and was not seen for DENV-3 in the following year. Human population density was another important factor in the intensity of viral circulation. Neither DENV-1 nor DENV-2 fit this model for 2001 or 2003. Since the vector has limited flight range and vector densities fail to correlate with intensity of viral circulation, this distribution represents the movement of infected people and to some extent mosquitoes. This pattern may mimic person-to-person spread of a new infection.

    Full Text Available OBJECTIVE Collection of triatomines in domestic, peridomestic and sylvatic environments in states of Bahia and Rio Grande do Sul, Northeastern and Southern Brazil respectively, and isolation of Trypanosoma cruzi strains. METHODS First, the captured triatomines were identified using insect identification keys, then their intestinal content was examined by abdominal compression, and the samples containing trypanosomatid forms were inoculated in LIT medium and Swiss mice. RESULTS Six triatomine species were collected in cities in Bahia, namely Panstrongylus geniculatus (01, Triatoma melanocephala (11, T. lenti (94, T. pseudomaculata (02, T. sherlocki (26 and T. sordida (460, and two in cities in Rio Grande do Sul, namely T. circummaculata (11 and T. rubrovaria (115. Out of the specimens examined, T. cruzi was isolated from 28 triatomine divided into four different species: T. melanocephala (one, T. lenti (one, T. rubrovaria (16 and T. sordida (10. Their index of natural infection by T. cruzi was 6.4%. CONCLUSIONS The isolation of T. cruzi strains from triatomines found in domestic and peridomestic areas shows the potential risk of transmission of Chagas disease in the studied cities. The maintenance of those T. cruzi strains in laboratory is intended to promote studies that facilitate the understanding of the parasite-vector-host relationship.

    Uranium mining and processing at Lagoa Real (Bahia, Brazil) in the southwest of Bahia state started in the year 2000.The processing of uranium ore for obtaining U3O8 (yellowcake) is done today in the processing unit of the Brazilian Nuclear Industries INB located in the area of the same municipality above mentioned. The production capacity is 400 tons / year of U3O8, and the reserves in this region are estimated at 100.000 tons of uranium without any other associated minerals, enough to supply the demand for nuclear power plants Angra I and II for over 100 years. Since the granting of AOP (Permanent Operation Authorization) by CNEN (National Commission on Nuclear Energy) in the year 2009, there were some incidents at the facility, such as: solvents and liquid containing uranium overflow; pipes rupture, causing indiscriminate dispersion of toxic acids and other chemical agents; collapse of parts of the slope of the open pit. CNEN admitted in an official press release on April 1, 2011 that 'INB has no capacity to produce annual reports on environmental monitoring (unable to perform radiometric measurements, etc.). The last time a report was released happened in the year 2008. These reports are vital to the environmental impact assessment of the facility'. Another potential source of environmental and health negative impacts on the local population could be linked to radon emission. What are the levels of this important pollutant in the affected areas?

    Full Text Available The laboratory and field observations summarized in this paper on visceral leishmaniasis ecology in the State of Bahia, Brazil are based on the author's observations over the past 35 years in a number of state's foci, public health records and literature citations. The disease is endemic with epidemic outbreaks occurring every ten years and its geographical distribution is expanding rapidly in the last years. Leishmania chagasi is the main ethiologic agent of the visceral leishmaniasis but Le. amazonensis s. lato was the only leishmania isolated by other authors from some visceral leishmaniasis human cases in the state. Lutzomyia longipalpis (with one or two spots on tergites III and IV and two sized different populations was epidemiologically incriminated as the main vector. It was found naturally infected with promastigotes, and it was infected with four species of leishmanias in the laboratory. Although the experimental transmission of Le. amazonensis by the bite of Lu. longipalpis to hamsters was performed, the author was not successful in transmitting Le. chagasi in the same way. The dog is the most important domestic source for infection of the vector, however it is not a primary reservoir. The opossum Didelphis albiventris was found naturally infected with Le. chagasi but its role as reservoir is unknown. Foxes and rodents were not found infected with leishmanias in Bahia.

    Full Text Available Restinga is a coastal ecosystem covering almost the entire Brazilian coast line and it is associated with the Atlantic Forest biome and therefore is a complementary component of the landscape. Its vegetation is highly variable and specialized, being influenced by salt, and with low fertility and moist soil. This environmental landscape promotes the colonization of species from contiguous biomes and ecosystems, thereby promoting high diversity, especially on the northern coast of Bahia. The study was conducted at the Reserva Imbassaí, in the municipality of Mata de São João, northern coast of Bahia, Brazil. We conducted six surveys distributed over one year, with samples every two months; we used the sampling techniques of active visual search, random encounters and pitfall traps along a linear transect. Fourty-nine snakes from 15 species distributed among five families were recorded: Boidae (2, Colubridae (3, Dipsadidae (6, Elapidae (1 and Viperidae (3. Ten of the species of snakes found at Reserva Imbassaí complement the literature overall snakes’ list from the north coast of Bahia’s restinga. The results show that Reserva Imbassaí is uniquely rich in snakes and therefore represents an important contribution to the knowledge of this taxon within the Atlantic forest hotspot.

    An ecological study was carried out with the aim of analyzing the evolution of inequalities in mortality in Salvador, Bahia State, Brazil, between 1991 and 2006. The city was divided into four social strata from 95 geographic Information Zones. The variables used for social stratification were education level and income of heads of households. Crude and age-standardized mortality rates, age specific mortality rates, proportional Infant mortality and the proportional mortality ratio, were calculated for each zone and social strata. Data was obtained from Death Certificates and the Populational Census. Although differences between strata were smaller in 2000 than in 1991, they persist and are still high, ranging from 28.7% to 65.5%. The differences between Information Zones were as much as 575%. The authors discuss the shortcomings of information systems, recommending that health indicators should be estimated by social classes and pointing out the limits and possibilities of the methodology used here.

    This study investigated the health of natural stocks of the oyster Crassostrea rhizophorae on the southern coast of Bahia in northeastern Brazil, during summer and winter 2010, at three localities (sampling points) in the estuaries of the Maraú (Camamu Bay) and Graciosa rivers. A total of 180 oysters (30/sampling point/season) were examined macroscopically for the presence of pathogens and anatomical changes. The specimens were subsequently fixed in Davidson solution, processed for paraffin embedding, sectioned and stained with Harris' hematoxylin and eosin. Histological analysis revealed the presence of Rickettsia-like organisms (RLOs), Ancistrocoma, Trichodina, Sphenophrya, Nematopsis, Urastoma, Bucephalus in the sporocyst phase, a nonspecific metacercaria, and a metacestode of genus Tylocephalum. The prevalence of infection was low except for parasitism by Nematopsis sp. which also caused histopathological changes. The presence of Bucephalus sp. caused parasitic castration. These two pathogens significantly affect the health of C. rhizophorae.

    This study analyzes nutritional status, estimates the prevalence of overweight and abdominal obesity, and investigates factors associated with these outcomes in a two-stage random sample of adults (> 20 years) in quilombos (communities that descend from African slaves) in Vitória da Conquista, Bahia State, Brazil, in 2011. Among 739 participants, prevalence rates were 31.8% and 10.2% for overweight and obesity, respectively, and 55.7% for increased waist-to-height ratio (> 0.50). Prevalence of overweight was higher among 30-39-year-olds, while abdominal obesity was more frequent among older individuals. Female sex, eating chicken or beef with untrimmed fat, and hypertension were associated with higher odds of overweight and abdominal obesity, while smoking and single marital status were associated with lower odds. The results show high prevalence rates for overweight and abdominal obesity in these very poor and socially isolated communities. Specific preventive and control measures are urgently needed.

    Full Text Available This study constitutes a first attempt to describe the genetic population structure of Mycobacterium tuberculosis circulating in Salvador, Bahia State, Brazil. A total of 56 confirmed cases of pulmonary tuberculosis, identified between March and June 2008, were analyzed using restriction fragment length polymorphism (IS6110-RFLP. The study population was characterized by a predominance of males (71.43% over 30 years of age (68.75%. Forty-one isolates were found to belong to a single pattern (73.2%, while 15 (26.7% were found in group patterns, forming six clusters. The higher level of diversity observed is much more suggestive of endogenous reactivation than recent transmission.

    In this article are reported the results of a study on the concentration of ascorbic acid (AA) in Mangifera indica as passive monitor and in Phaseolus vulgaris as active monitor with the intention to study the effects of industrial emissions from the Petrochemical Complex of Camaçari (PCC), Bahia, Brazil, on the vegetation. Leaves from M. indica were collected in two sites in the region under direct influence of industrial emissions and in one presumed nonpolluted reference (background) site. Pots with P. vulgaris were exposed in the same sites. The AA increase in the leaves of M. indica from PCC sites indicates a stress situation. The small AA increase in the P. vulgaris exposed in the more polluted site indicates that the active monitor is a sensitive one. The decrease of its leaf area indicates the inability of this species to activate physiological protection mechanisms like an increase in AA production.

    Full Text Available This paper deals with the use of insects as medicinal resources by inhabitants of the county of Pedra Branca, which is located in the interior of Bahia State, northeastern Brazil. The survey was carried out from February to May 2001 by conducting open-ended interviews with 52 informants of both sexes, aged over 30. The value of each of the entomotherapeutic resources was estimated through its relative importance (RI, a versatility measure. A total of 27 kinds of insects was recorded as being medicinally useful in the treatment of locally diagnosed illnesses and symptoms. The order Hymenoptera was predominant, with 12 kinds represented. The recording of the usage of medicinal insects in this locality provides a relevant contribution to the phenomenon of zootherapy. Biochemical and pharmacological studies are needed to promote the development of new drugs for the improvement of human health.

    Discussions on the health-disease process and health promotion indicate the need to reach beyond the limits of the health sector itself to link knowledge from various fields in order to promote better health conditions for the population. Inter-sector approaches have thus emerged as a new rationale for guiding public policies. This study aimed to analyze the implementation of inter-sector actions in social mobilization for dengue control in Bahia State, Brazil, from 2008 to 2009, using evaluative research. A log frame was developed to define criteria for assessing the degree of implementation of the above-mentioned actions (implemented; partially implemented; not implemented). The results identified political support from government agencies as the main positive factor for inter-sector practices. Barriers included the concentration of responsibilities in a single sector and lack of planning as a work tool. The results emphasize inter-sector linkage as a persistent challenge.

    A sample of 101 specimens of the unisexual whiptail lizard Cnemidophorus nativo (Squamata; Teiidae) from a coastal site in Bahia State, Brazil were examined for the presence of endoparasites. Of these, 35 (34.7%) harboured helminths. Six helminth species were recovered from C. nativo, including five nematodes (Physaloptera retusa, Physalopteroides venancioi, Subulura lacertilia, Skrjabinelazia intermedia and Parapharyngodon sp., and one cestode (Oochoristica ameivae), all representing new host records. Most lizards were infected by a single species of helminth and none by more than three. Infection rates were neither significantly influenced by host body size nor by environmental factors. The results are compared with data from studies on other whiptail species in both South and North America.

    Full Text Available This essay presents some issues for discussion about the relationship between the tourist market and the sex trade in the city of Salvador, capital of Bahia State, situated in northeastern Brazil, focusing particular attention to the issue of gender relationships. Whereas tourism an important social mediator, it is proposed, based on some observations made in interviews with ten sex workers working in this city sights, dialoguing with other researchers of this theme, on the social and cultural relations between tourists and native, which may reflect elements of a broader reality, and through the interpretation of the ways in which the relationships between those involved in such a context are developed on the tourism and especially about his bias known as sexual tourism. It's worth noting that in the discussions presented here, we discuss only the female heterosexual prostitution.

    Full Text Available A remarkable new species of pulmonate snail was recently collected in a small Atlantic Rainforest fragment near the city of Canavieiras, state of Bahia, Brazil, an area known for a high diversity of land snails. It is described herein as Leiostracus fetidus sp. nov. and can be easily identified by its color pattern of irregular brown to black axial stripes on a white to yellow background, a reddish axial band "separating" the white peristome from the rest of the shell and a broad brown spiral band surrounding the umbilical region. Other diagnostic features include a relatively small size, a proto columellar fold and two very weak folds delimiting the basal region of the aperture. This discovery is a reminder of how little this fauna is known and also an alarm for proper conservation of these forest fragments.

The other haplotypes (1, 5, 9, 11, 12, 13, 14 and 16 had lower frequencies. Restriction site analysis and the derived haplotypes indicated homogeneity among the populations. Thirty-two individuals with hemoglobinopathies (17 sickle cell disease, 12 HbSC disease and 3 HbCC disease were also analyzed. The haplotype frequencies of these patients differed significantly from those of the general population. In the sickle cell disease subgroup, the predominant haplotypes were BEN (Benin and CAR (Central African Republic, with frequencies of 52.9% and 32.4%, respectively. The high frequency of the BEN haplotype agreed with the historical origin of the afro-descendant population in the state of Bahia. However, this frequency differed from that of Salvador, the state capital, where the CAR and BEN haplotypes have similar frequencies, probably as a consequence of domestic slave trade and subsequent internal migrations to other regions of Brazil.

    Full Text Available ABSTRACT: There is a large number of studies evaluating methods to quantify biomass for the genus Pinus in different regions of Brazil. However, knowledge about this subject in the Northeast region of Brazil is still incipient. The objective of the present study was to assess the biomass and carbon stocks and select mathematical models to estimate these variables in Pinus caribaea var. hondurensis , which is established in homogenous stands in the Southwest region of the state of Bahia (Brazil. The biomass was quantified using the destructive method. Samples of needles, bole, bark, and branches were analyzed to determine their carbon contents. Ten models were tested, and the best of them were chosen based on the following statistical indicators: adjusted determination coefficient, estimate standard error, maximum likelihood logarithm, and graphical analysis of waste. Values for total biomass and carbon stocks were 69 and 42Mg ha-1, respectively. Curtis and Schumacher-Hall Log models showed to be the most indicated to estimate the total dry biomass and carbon of the species under the conditions studied.

    In front of the global trend for developing new ways of energy that pollute less and are renewable, Brazil emerges as a major actor in the development and use of technology for the production of biofuels. In the context of the potential of semi-arid to produce some oil used in production, the Brazilian government is enabling the production of Northeastern region. The State of Bahia is the largest producer of castor oil from Brazil, with an estimated production of 102.8 thousand tonnes of grain in the season 2008/2009 (CONAB, 2009). The development of the sector depends on appropriate government actions to support their competitive sustainability, and encouraging the improvement of management techniques in all involved. In that scenario, the logistics contributes to the development of this sector through the supply chain management. One conclusion is that the competitiveness and sustainability of the supply chain of castor in the Semi-arid of Bahia practices depends on the adoption of integrated logistics, without which the current failures prevent the consolidation of governmental objectives defined.

    Trichoptera is the most species-rich clade of exclusively aquatic insects. In Brazil, 645 species have been recorded, distributed in 70 genera and 16 families. In the Northeast Region of Brazil, 85 species have been recorded, including 56 in Bahia State. Sixteen of the Northeast Region species belong to the family Leptoceridae. Among these, the long-horned caddisfly genus Neoathripsodes Holzenthal has been a monotypic genus since its erection more than 26 years ago. It is an endemic genus in the states of Minas Gerais, Rio de Janeiro and São Paulo and only the male stage has been described for its only known species, Neoathripsodes anomalus. In this paper, we describe a new species of Neoathripsodes, with the first description of a female in this genus. Additionally, we present new records for the family Leptoceridae in Bahia, especially from the Serra Bonita Mountains, in order to help solve a long-term problem in Brazilian caddisfly research: An uneven proportion of studies in some regions of the country due to historical reasons. The Northeast Region of Brazil still remains a neglected area in which efforts to unearth its biodiversity should be focused. In this work, four species are recorded for the first time for Bahia State and its Serra Bonita Mountains: Grumichella rostrata Thienemann 1905, Neoathripsodes holzenthali n. sp., Nectopsyche fuscomaculata Flint 1983, and Notalina cipo Holzenthal 1986. Neoathripsodes and Notalina are new generic records for Bahia State. The following four species are new records for Serra Bonita: Atanatolica bonita Costa & Calor 2014, Oecetis martinae Quinteiro & Calor 2015, O. furcata Quinteiro & Calor 2015, and Triplectides gracilis (Burmeister 1839). Additional new distributional records for Bahia State are included in this study.

    Use of health services is increasing in Brazil as a whole, but geographic and social inequalities persist, especially among minority groups. The aim of this study was to analyze the use of health services by members of quilombos (slavedescendant African-Brazilian communities) in Vitória da Conquista, Bahia State, Brazil. This cross-sectional health survey in 2011 focused on 797 adults (≥ 18 years old) belonging to quilombos. The magnitude of the associations between explanatory variables and use of services was estimated by the prevalence ratio obtained from Poisson regression with 95% confidence interval. Of the total sample, 455 (57.1%) reported having used health services in the 12 months prior to the interview. Higher rates of health services utilization were associated with female gender, non-single conjugal status, fair, poor, or very poor self-rated health, enrolment in the Family Health Program, and referral to a health facility for regular or on-going care. The results showed underutilization of health services by members of quilombos, thus demonstrating the need to improve health services provision for this population group.

    Full Text Available Despite the serious threats that affect shark species living along the central coast of Brazil, knowledge about the life history of these animals is still scarce. The present study describes the knowledge and perceptions of fishermen from southern Bahia, Brazil, on the trophic interactions of sharks. The objective of this work was to generate information that contributes to a better understanding of the life history of sharks from this poorly known region. In 2012, semi-structured interviews were conducted with 65 fishermen, with over 15 years of experience, about fisheries and aspects of shark feeding behavior. The study found that the participants have comprehensive ethno-ecological knowledge about shark feeding habits, describing 39 types of items as components of the diets of these animals. They are also able to recognize the favored items in the diet of each ethnospecies of shark. Similar studies about shark feeding habits along the Brazilian coast should be developed. This will generate more detailed knowledge and/or new scientific hypotheses about the interspecific relationships of these predators and their prey.

    This cross-sectional study was conducted to find out the factors associated with food insecurity (FI) in households of the students aged 6-12 years in public schools of Salvador city, Bahia, Brazil. The study included 1,101 households. Food and nutritional insecurity was measured using the Brazilian Food Insecurity Scale (BFIS). Data on socioeconomic and demographic characteristics as well as environmental and housing conditions were collected during the interviews conducted with the reference persons. Multivariate polytomous logistic regression was used in assessing factors associated with food insecurity. We detected prevalence of food insecurity in 71.3% of the households. Severe and moderate forms of FI were diagnosed in 37.1% of the households and were associated with: (i) female gender of the reference person in the households (OR 2.21, 95% CI 1.47-3.31); (ii) a monthly per-capita income below one-fourth of the minimum wage (US$ 191.73) (OR 2.63, 95% CI 1.68-4.08); (iii) number of residents per bedroom below 3 persons (OR 1.91, 95% CI 1.23-2.96); and (iv) inadequate housing conditions (OR 1.84, 95% CI 1.12-4.49). Socioeconomic inequalities determine the factors associated with FI of households in Salvador, Bahia. Identifying vulnerabilities is necessary to support public policies in reducing food insecurity in the country. The results of the present study may be used in re-evaluating strategies that may limit the inequalities in school environment.

    Zika virus (ZIKV) disease outbreaks occurred in French Polynesia in 2013-2014 and in Brazil and Colombia in 2015-2016, respectively. Using our recently developed ZIKV disease model, we simulated the reported ZIKV infection cases from French Polynesia, Colombia and the State of Bahia of Brazil. Moreover, we estimated that the infection attack rates were 78.0% (95% confidence interval (CI): 63.5-86.3%) in French Polynesia which closely matches a previous serological study; 20.8% (95% CI: 1.1-50.0%) in Colombia which suggests that the attack rate was most likely less than 50%; and 32.4% (95% CI: 2.5-94.2%) in the State of Bahia in Brazil which suggests that the attack rate is unidentifiable with monthly data in Bahia. Furthermore, we found that the association of precipitation and ZIKV outbreak was more evident in Colombia than the other two places. These results are helpful for us to understand the possible evolution, to control the on-going outbreaks, to prevent the potential geographic spread, and to study the ecological and epidemiological characteristics of ZIKV.

    Fishermen's knowledge is a source of indispensable information in decision-making processes related to efforts to stimulate the management and conservation of fishing resources, especially in developing countries. This study analyzed the knowledge of fishermen from three municipal areas of Bahia in northeast Brazil regarding the behavior repertoire of sharks and the possible influence that these perceptions may have on the inclination to preserve these animals. This is a pioneering study on the ethnobiological aspects of elasmobranchs in Brazil. Open, semi-structured interviews with shark fishing specialists were conducted between September 2011 and October 2012. The interviews addressed the fishermen's profile, fishing techniques and knowledge about sharks, focusing on the behaviours exhibited by sharks. The data were analysed with quantitative approach and conducted with the use of descriptive statistical techniques. Sixty-five fishermen were interviewed. They descend from the rafting subculture of Brazil's northeast, which has historically been disregarded by public policies addressing the management and conservation of fishing resources. The fishing fleet involved in shark fishing includes rafts, fishing boats and lobster boats equipped with fishing lines, gillnets, longlines and "esperas". The informers classified sharks' behaviour repertoire into 19 ethological categories, related especially to feeding, reproduction, and social and migratory behaviours. Because they identify sharks as predators, the detailed recognition of the behaviours exhibited is crucial both for an efficient catch and to avoid accidents. Therefore, this knowledge is doubly adaptive as it contributes to safer, more lucrative fishing. A feeling of respect for sharks predominates, since informers recognize the ecological role of these animals in marine ecosystems, attributing them the status of leader (or "the man") in the sea. This work demonstrates the complexity and robustness of

    This contribution reports the parasites found in the mangrove mussel Mytella guyanensis in Camamu Bay, Bahia, Brazil. Samples were collected monthly from September 2006 through October 2007. A total of 460 individuals were collected, fixed in Davidson's solution, and processed by standard histological techniques, and the sections were stained with Harris hematoxylin and eosin (H&E). The water temperature ranged from 23.5 to 31.6 ºC, and the salinity from 25 to 37‰. Microscopic analysis showed Rickettsia-like organisms (RLOs), Nematopsis sp. (Apicomplexa), and Platyhelminthes, including a turbellarian, sporocysts of Bucephalus sp., metacercariae, and metacestodes of Tylocephalum sp. Parasites were observed mainly in the gills, mantle, and digestive gland. The prevalence of Nematopsis sp. was 100%, and in heavily infected mussels the tissues of the labial palps were damaged. RLOs occurred in high prevalence and intensity of infection in some periods. The digenean sporocysts showed moderate prevalence but high intensity of infection, and caused parasitic castration. In general, there was no significant spatial or temporal variation (p > 0.05) of the parasites, which is probably attributable to the small variations of temperature and salinity in the region.

    This study investigated the parasites of three commercially important bivalve species (Crassostrea rhizophorae, Mytella guyanensis and Lucina pectinata) from the southern coast of Bahia, Brazil. A total of 540 specimens were collected in August 2009 and February 2010, at three localities. The bivalve specimens were measured on their longest axis, opened, and macroscopically examined for the presence of parasites or signs of disease. They were then fixed in Davidson' solution and subjected to routine histological processing, with paraffin embedding and H&E staining; next, the specimens were examined under a light microscope. No parasites were observed associated with L. pectinata. Rickettsia-like organisms (RLOs), Sphenophrya sp. (Ciliophora), Nematopsis sp. (Apicomplexa), Urastoma sp. (Turbellaria) and Bucephalus sp. (Digenea) were observed in both C. rhizophorae and M. guyanensis, as well as Ancistrocoma sp. (Ciliophora) and Tylocephalum sp. (Cestoda) in the former. A high prevalence of Nematopsis sp. was seen, but caused no apparent damage to the host. Bucephalus sp. caused the destruction of tissues, with castration, but showed low prevalence. The other parasites occurred in low prevalence and intensity, without causing significant damage.

    The use of cuprous fungicides in cocoa production in the southern part of the state of Bahia (Brazil) for decades has caused an accumulation of copper in various components of the cocoa plantations, and a contamination of regional freshwater ecosystems is suspected. Urban and industrial sources are supposed to contribute to water pollution and eutrophication of the Rio Cachoeira, the main river in this region. In order to study the metal contamination and nutritional status of this freshwater ecosystem, samples of the aquatic macrophytes Eichhornia crassipes and Pistia stratiotes were collected at seven sites along the river course. The samples were analysed for their copper, aluminium, chromium, nitrogen and phosphorus concentrations. The levels of heavy metals increased in the downstream direction, particularly in the roots of water hyacinth. A dramatic increase of nitrogen and phosphorus concentrations in water as well as in plant tissues was found in samples collected downstream from the city of Itabuna. Metal input and eutrophication were attributed to agricultural, industrial and urban sources in the region. Biomonitoring of the water quality using aquatic macrophytes as accumulative indicator plants is recommended in addition to chemical water analyses.

    An ecological study was carried out using information zones as units of analysis in order to assess the evolution of socio-spatial inequalities in mortality due to external causes and homicides in Salvador, Bahia State, Brazil, in 2000 and 2006. The Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística--IBGE) and the City Health Department (Secretaria Municipal de Saúde) provided the data sources, and causes of death were reviewed and reclassified based on reports from the Institute of Legal Medicine (Instituto Médico Legal). The information zones were classified into four social strata according to income and schooling. The ratio between mortality rates (inequality ratio) was calculated and confirmed a rise of 98.5% in the homicide rate. In 2000, the risk of death due to external causes and murders in the stratum with the worst living conditions was respectively 1.40 and 1.94 times greater than in the reference stratum. In 2006 these figures were 2.02 and 2.24. The authors discuss the implications for inter-sectoral public policies, based on evidence from the study's findings.

    The uranium from Lagoa Real (Bahia/Brazil) is associated with syenitic magmatism (1904 {+-}44 Ma minimum age from upper intercept of zircon U-Pb discordia by LA-ICP-MS) belonging to a mafic/ felsic lithologic association linked to the final stages of 2.05-1.80 Ga Orosirian Orogeny, which acted in the Paramirim Block. These syenitic rocks are rich not only in albite, but also in U-rich titanite (source of uranium). In association with the development of the Orosirian ductile shear zones, the syenites were crystallized and deformed. The metamorphic reactions, which include intense recrystallization of magmatic minerals, led uraninite to precipitate (1868 {+-} 69 Ma; U-Pb by LA-ICP MS) under Redox control. A second population of uraninites was also generated by shear zones reactivation during 0.6-0.5 Ga Brasiliano Orogeny (605 {+-} 170 Ma; U-Pb by LA-ICP-MS). The geotectonic implications are: a) the importance of the Orosirian event in the Paramirim Block during paleoproterozoic Sao Francisco/Congo Craton edification and b) the influence of the Brasiliano event in the Paramirim Block during the West-Gondwana assembly processes, indicated by the 605 {+-} 170 Ma uraninite (second population) age and by the 483 {+-} 100 Ma lower intercept of the metamorphosed syenite U-Pb discordia.

    Full Text Available Areas of restinga are geologically recent environments. The species that inhabit this type of ecosystem are typical of adjacent areas, such as rain forest, tabuleiro forest and caatinga, and form a diverse community of trees, shrubs and erect and prostrate herbs. The goal of this work was to evaluate the vegetation in an area of restinga located along Praia do Forte, in the state of Bahia, Brazil. Four 200m transects where made within five plots of 100m2 each, and 1,640 individuals within 68 species were collected. High species diversity was found in transects 1 and 2 (H´ = 3.882 and 3 and 4 (H´ = 3.835. The most representative families were Myrtaceae, Rubiaceae and Malpighiaceae. Based on the species composition, a significant difference (p < 0.001 was found between the sampled areas, and the findings show that there are two distinct plant communities in this region, Mata deRestinga and Restinga em Moitas.

    Shaded perennial agroforestry systems contain relatively high quantities of soil carbon (C) resulting from continuous deposition of plant residues; however, the extent to which the C is sequestered in soil will depend on the extent of physical protection of soil organic C (SOC). The main objective of this study was to characterize SOC storage in relation to soil fraction-size classes in cacao ( Theobroma cacao L.) agroforestry systems (AFSs). Two shaded cacao systems and an adjacent natural forest in reddish-yellow Oxisols in Bahia, Brazil were selected. Soil samples were collected from four depth classes to 1 m depth and separated by wet-sieving into three fraction-size classes (>250 μm, 250-53 μm, and cacao AFSs, the C contained in the macroaggregate fraction might become stabilized in the soil. The study shows the role of cacao AFSs in mitigating greenhouse gas (GHG) emission through accumulation and retention of high amounts of organic C in the soils and suggests the potential benefit of this environmental service to the nearly 6 million cacao farmers worldwide.

    Full Text Available Regarded as relevant nursery areas for fishes, the estuarine systems shelter many commercially important species. From October 2008 to November 2009, we investigated the ichthyofaunal composition and described the routine of artisanal fishing with camboa net in the estuary at the Cassurubá Extractive Reserve, Bahia, Brazil. Samplings were conducted in three rivers, during the new and full moons. A total of 1,074 fishes were caught in 17 fisheries with nets, belonging to 26 species and 17 families, with a total biomass of 378.4 kg. The Gerreidae and Centropomidae families were the most abundant ones, and there was a predominance of catches. Out of the total, 50% of individuals which were at the first gonadal maturation (L50 described in the literature had a size less than the expected one, indicating growth overfishing. We recommends the establishment of management systems shared between the actors involved in this fishing art and the Cassurubá Extractive Reserve managers, in order to reduce the capture of individuals below the first gonadal maturation size.

OBJECTIVE: To determine the frequency of VVC and to describe the main Candida species isolated and their susceptibility to antifungal drugs in HIV-infected patients, compared to HIV-uninfected women in Salvador, Brazil. METHODS: Cross-sectional study including a group of 64 HIV-infected women and 76 uninfected women, followed up at the AIDS reference center and at the Gynecological Clinic of Escola Bahiana de Medicina e Saúde Pública (Salvador, Bahia, Brazil. RESULTS: Frequency of Candida spp. was higher in HIV-infected women (29.7% than in HIV-uninfected controls (14.5% (p = 0.02. The odds ratio value for vulvovaginal candidiasis in HIV-infected patients was 2.6 (95% CI: 1.07 - 6.32 p = 0.03. Candida albicans was the most commonly isolated species in both HIV-infected (52.3% and uninfected women (85.7%, followed by C. parapsolis in 17.6% and 14.3%, respectively. In HIV-infected women, C. glabrata, C. parapsilosis, and a coinfection of C. albicans and C. glabrata were also identified. There was no significant difference between Candida species isolated from the vaginal mucosa of women with VVC and colonization of the vaginal mucosa of HIV-infected and HIV-uninfected women. One C. glabrata isolate from an HIV-infected patient was resistant to fluconazole and other two isolates exhibited a dose-dependent susceptibility. CONCLUSION: Our results confirm a higher frequency of Candida spp. isolated from the vaginal mucosa of HIV-infected women and a broader spectrum of species involved. Only Candida glabrata isolates showed decreased susceptibility to fluconazole.

    Full Text Available ABSTRACT In the State of Bahia, Brazil, the citrus industry is located on the north coast with the prevalence of the combination ‘Pera’ sweet orange on ‘Rangpur’ lime. Scion-rootstock diversification may contribute to the increase of yield and the extension of harvest season, as long as to decrease the risk associated to abiotic and biotic stresses. Therefore, the performance of ‘Tuxpan Valencia’ sweet orange grafted onto 14 rootstocks was evaluated in Rio Real – BA. Planting was performed in 2006 under rainfed cultivation on cohesive ultisol and tree spacing of 6.0 m x 4.0 m. Tree size, yield and fruit quality were evaluated in the period of 2010-2014, in addition to tree survival at nine years old and drought tolerance in the field based on leaf wilting. In the evaluated conditions, ‘Sunki Tropical’ and ‘Sunki Maravilha’ mandarins led to the highest scion canopy volume. The highest accumulated yield in five harvests was recorded on ‘Santa Cruz Rangpur’ lime, ‘Volkamer’ lemon, ‘Riverside’ and ‘Indio’ citrandarins, ‘Sunki Tropical’ mandarin and the hybrid TSKC x (LCR x TR – 001. ‘Riverside’ and TSKFL x CTSW – 049 induced higher yield efficiency on the canopy. The rootstocks did not influence the tree survival nine years after planting except for lower survival of TSKFL x CTSW – 049. Drought tolerance was not affected either. Regarding to the fruit quality of ‘Tuxpan Valencia’, the rootstocks influenced the juice content, soluble solids and technological index with the citrandarins, ‘Santa Cruz Rangpur’ lime, ‘Volkamer’ lemon and ‘Sunki Tropical’ mandarin presenting higher performance in general.

    Shaded perennial agroforestry systems contain relatively high quantities of soil carbon (C) resulting from continuous deposition of plant residues; however, the extent to which the C is sequestered in soil will depend on the extent of physical protection of soil organic C (SOC). The main objective of this study was to characterize SOC storage in relation to soil fraction-size classes in cacao (Theobroma cacao L.) agroforestry systems (AFSs). Two shaded cacao systems and an adjacent natural forest in reddish-yellow Oxisols in Bahia, Brazil were selected. Soil samples were collected from four depth classes to 1 m depth and separated by wet-sieving into three fraction-size classes (>250 microm, 250-53 microm, and <53 microm)-corresponding to macroaggregate, microaggregate, and silt-and-clay size fractions-and analyzed for C content. The total SOC stock did not vary among systems (mean: 302 Mg/ha). On average, 72% of SOC was in macroaggregate-size, 20% in microaggregate-size, and 8% in silt-and-clay size fractions in soil. Sonication of aggregates showed that occlusion of C in soil aggregates could be a major mechanism of C protection in these soils. Considering the low level of soil disturbances in cacao AFSs, the C contained in the macroaggregate fraction might become stabilized in the soil. The study shows the role of cacao AFSs in mitigating greenhouse gas (GHG) emission through accumulation and retention of high amounts of organic C in the soils and suggests the potential benefit of this environmental service to the nearly 6 million cacao farmers worldwide.

    Full Text Available In tropical forests with low seasonality, climatic variables generally exert a weak influence on the phenology of species. The seasonality of phenophases in closely related taxa can be controlled by phylogenetic constraints in such environments. In this study, our aim was to describe the phenology of Rubiaceae in the understory of the Atlantic Forest in the southern part of Bahia, Brazil, as well as to evaluate the seasonality and phenological synchrony of this family. For two years, we observed 90 individuals belonging to 13 species, in an area of 0.2 ha. Leaf flushing and leaf fall did not demonstrate any seasonality, were continuous for most species and correlated with few of the climatic variables. Flowering was seasonal and correlated positively with all climatic variables. Species exhibited seasonality for this phenophase with high flowering overlap among species of Psychotria, indicating an aggregated pattern for this genus. Fruiting was also seasonal and correlated with all the climatic variables, unripe fruit development peaking at the beginning of the season during which humidity is highest and fruit ripening peaking in the season during which humidity is slightly lower. The vegetative and flowering patterns observed in the study area are commonly seen in other tropical forests. The reproductive seasonality of this family can facilitate the attraction of biotic agents, as postulated in the facilitation hypothesis. Our results demonstrate that climatic variables influenced the phenological patterns observed here, although the high reproductive seasonality and interspecific synchrony, especially in congeneric species, raises the possibility that phylogenetic proximity plays a role in the pattern of the family Rubiaceae.

    Full Text Available Environmental changes have a strong influence on the emergence and/or reemergence of infectious diseases. The city of Salvador, Brazil -currently the focus of a housing boom linked to massive deforestation- is an example in point as the destruction of the remaining areas of the Atlantic Forest around the city has led to an increased risk for Chagas disease. Human domiciles have been invaded by the triatomine vectors of Trypansoma cruzi, the flagellate protozoan causing Chagas disease, a problem of particular concern in urban/suburban areas of the city such as the Patamares sector in the north-east, where numbers of both the vector and human cases of the disease have increased lately. To control and prevent further deterioration of the situation, the control programme for Chagas disease, developed by the Bahia Center for Zoonosis Control, has divided the area into a grid of designated surveillance units (ZIs that are subjected to vector examination. In six out of 98 of these ZIs, 988 triatomes were collected and georeferenced during the 3-year period between 2006 and 2009. The hottest months, that are also generally the driest, showed the highest numbers of triatomines with Triatoma tibiamaculata being the predominant species (98.3% with Panstrongylus geniculatus present only occasionally (0.6%. Fifty-four percent of all triatomines captured were found inside the homes, and 48.6% out of 479 individuals in the affected ZIs selected for analysis tested positive for T. cruzi infection. The study presented here is a pioneering initiative to map the spatial distribution of triatomines based on geographical information systems with the additional aim of contributing to an expanded knowledge-base about T. cruzi and its vectors in urban areas and raise public health awareness of the risks involved.

    BetaS-Globin haplotypes were studied in 80 (160 betaS chromosomes) sickle cell disease patients from Salvador, Brazil, a city with a large population of African origin resulting from the slave trade from Western Africa, mainly from the Bay of Benin. Hematological and hemoglobin analyses were carried out by standard methods. The betaS-haplotypes were determined by PCR and dot-blot techniques. A total of 77 (48.1%) chromosomes were characterized as Central African Republic (CAR) haplotype, 73 (45.6%) as Benin (BEN), 1 (0.63%) as Senegal (SEN), and 9 (5.63%) as atypical (Atp). Genotype was CAR/CAR in 17 (21.3%) patients, BEN/BEN in 17 (21.3%), CAR/BEN in 37 (46.3%), BEN/SEN in 1 (1.25%), BEN/Atp in 1 (1.25%), CAR/Atp in 6 (7.5%), and Atp/Atp in 1 (1.25%). Hemoglobin concentrations and hematocrit values did not differ among genotype groups but were significantly higher in 25 patients presenting percent fetal hemoglobin (%HbF) > or = 10% (P = 0.002 and 0.003, respectively). The median HbF concentration was 7.54+/-4.342% for the CAR/CAR genotype, 9.88 3.558% for the BEN/BEN genotype, 8.146 4.631% for the CAR/BEN genotype, and 4.180+/-2.250% for the CAR/Atp genotype (P = 0.02), although 1 CAR/CAR individual presented an HbF concentration as high as 15%. In view of the ethnic and geographical origin of this population, we did not expect a Hardy-Weinberg equilibrium for CAR/CAR and BEN/BEN homozygous haplotypes and a high proportion of heterozygous CAR/BEN haplotypes since the State of Bahia historically received more slaves from Western Africa than from Central Africa.

    The genus Burkholderia (β-Proteobacteria) currently comprises more than 60 species, including parasites, symbionts and free-living organisms. Several new species of Burkholderia have recently been described showing a great diversity of phenotypes. We examined the diversity of Burkholderia spp in environmental samples collected from Caatinga and Atlantic rainforest biomes of Bahia, Brazil. Legume nodules were collected from five locations, and 16S rDNA and recA genes of the isolated microorganisms were analyzed. Thirty-three contigs of 16S rRNA genes and four contigs of the recA gene related to the genus Burkholderia were obtained. The genetic dissimilarity of the strains ranged from 0 to 2.5% based on 16S rDNA analysis, indicating two main branches: one distinct branch of the dendrogram for the B. cepacia complex and another branch that rendered three major groups, partially reflecting host plants and locations. A dendrogram designed with sequences of this research and those designed with sequences of Burkholderia-type strains and the first hit BLAST had similar topologies. A dendrogram similar to that constructed by analysis of 16S rDNA was obtained using sequences of the fragment of the recA gene. The 16S rDNA sequences enabled sufficient identification of relevant similarities and groupings amongst isolates and the sequences that we obtained. Only 6 of the 33 isolates analyzed via 16S rDNA sequencing showed high similarity with the B. cepacia complex. Thus, over 3/4 of the isolates have potential for biotechnological applications.

    Tungiasis is a parasitic skin disease neglected by authorities, health professionals, and the general population. Its occurrence is significantly associated with poverty. A cross-sectional study was conducted to describe the prevalence of tungiasis, associated clinical signs and risk factors of the canine population at a tourist site in the city of Ilhéus, Bahia (northeast Brazil). All village households were visited and dogs inspected after authorization by owners. A semi-structured questionnaire was administered. Of the 114 dogs included in the study, 71 (62.3%) were infested; all of them had lesions on their pads. An ectopic lesion on the nose was observed in one dog (1.4%). The number of manipulated lesions outnumbered the number of vital and avital lesions with an average of 88.3%. Edema (95.8%) and hyperkeratosis (85.9%) were the most prevalent clinical signs. Behavioral disorders such as excessive licking (6/71; 8.5%), disobedience (1/71; 1.4%) and prostration (2/71; 2.8%) were reported. In the multi-variate analysis, semi-restricted condition of the dogs (adjusted OR=8.58; 95% CI=2.47-29.76) and the presence of sand on the compound (adjusted OR=14.23, 95% CI=2.88-70.28) were significantly associated with infestation. We concluded that, infestation with Tunga spp. is highly endemic in the canine population of the village. The low level of restrictions on dogs and the presence of sand in areas most frequented by the animals are perpetuating factors of infestation in the community, subject to integrated and multidisciplinary intervention measures.

    Full Text Available This article discusses the main findings and conclusions from my field research evaluating education reform in the state of Bahia, Brazil. Data collection was done during two exploratory research trips to Salvador, the state capital, in 2001 and in 2005. The Bahian Education Reform, initiated by the state government in 1999 and funded to a great extent by the World Bank, has achieved some very significant goals, most importantly the expansion of high school education and the broadening of access to primary education in areas where access was far from universal. My research nevertheless points to some sever shortcomings, namely with regard to the situation of Afro-Brazilians. Structural racism provides one of the strongest explanations for this shortcoming. Structural racism in Bahia lowers teachers' and principals' expectations about the potential for academic achievement of poor Afro-Brazilians; structural racism widens the gap between students and principals, contributing to a mutual alienation of this two groups and jeopardizing the creation of strategic alliances and synergies inside schools; and it alienates schools from neighborhoods, impeding meaningful community and parental involvement in school management. Finally, the low recognition that public teachers receive from society as a whole, reflected by low salaries, and a general lack of institutional incentive structures that reward outstanding performance and sanction under-average performance have transformed Bahian public education into a desperado system, where the motivations of teachers and students are systematically grinded and their hopes frustrated.Este artículo discute las conclusiones principales de mi investigación en la que evalúo la reforma escolar en el estado de Bahia, Brasil.

    The coastal zone and continental shelf along Morro de Sao Paulo to Itacare, despite having a great quantity of reefs, have only received a closer attention on this aspect in the last 5 years. Until then, there was only one scientific reference published by Charles F. Hartti, more than a century ago, in his work Geology and Physical Geography of Brazil. The beginning of petroleum exploration in Camamu-Almada Basin demanded a great effort to enhance knowledge of the reef ecosystem in the area. The assessments developed by El Paso since 2002, used visual censuses in band and line intercept transects, organized in the AGRRA and PETRORISCO protocols. Nowadays we have a detailed digital map of the reefs, as part of a GIS, containing information about reef vitality, that include reefs attached to the coast and reef Banks of the region in the vicinity of Pratigi, once known only to fishermen. This article presents a overview of the reefs mapped and its vitality described up to now. (author)

    Drug interactions are risk factors for the occurrence of adverse drug reactions. The risk for drug interactions includes factors related to prescription that are intrinsic to the patient. This study sought to evaluate the potential drug interactions in primary care prescriptions in Vitória da Conquista in the state of Bahia to fill the knowledge gap on this topic in Brazil. Information about several variables derived from the primary health care prescriptions was collected and drug interactions were evaluated based on information from Medscape and Micromedex(R) databases. Polypharmacy frequency and its association with the occurrence of drug interactions were also evaluated. Results revealed a 48,9% frequency of drug interactions, 74,9% of moderate or greater severity, 8,6% of prescriptions in polypharmacy that in the chi-square test showed a positive association with the occurrence of drug interactions (p < 0,001). Prescriptions from primary care in Vitória da Conquista in the state of Bahia showed a high frequency of drug interactions, however it is necessary to analyze other risk factors for their occurrence at this level of health care.

    Full Text Available Abstract Background This article records the traditional knowledge of crab gatherers in the city of Conde, in the North Coast Region of Bahia State, Northeastern Brazil. Methods Data on biological and ecological aspects of economically important brachyuran crustaceans have been obtained from semi-structured interviews and in loco observations conducted from September 2007 to December 2009. A total of 57 fishermen of both genders, aged between 10 and 78 years have been interviewed (individually or collectively in different contexts; interviewees were asked about aspects such as external morphology, life cycle, trophic ecology, and spatial and temporal distribution of the major economically important brachyuran crustaceans in the region. Seven fishing communities were visited: Siribinha, Sítio do Conde, Poças, Ilha das Ostras, Cobó, Buri and Sempre Viva. Data were analyzed by comparing the information provided by participants with those from the specialized academic literature. Results The results show that artisanal fishermen have a wide ranging and well-grounded knowledge on the ecological and biological aspects of crustaceans. Crab gatherers of Conde know about growth and reproductive behavior of the animals they interact with, especially with regard to the three major biological aspects: “molt”, “walking dance” and “spawning”. Conclusion This knowledge constitutes an important source of information that should be considered in studies of management and sustainable use of fishery resources in the North Coast Region of Bahia State.

Foram investigados a natureza jurídica, a capacidade instalada ambulatorial e hospitalar, a produção e o custo das consultas médicas segundo modalidades de financiamento público e privado. As diferentes formas de assistência médica supletiva são a principal fonte de financiamento da assistência ambulatorial, e 51,1% das unidades investigadas são independentes dos recursos públicos oriundos do Sistema Único de Saúde (SUS. Os convênios-empresa e o seguro saúde stricto sensu participaram de forma moderada e elevada do financiamento das consultas médicas, em 54% e 41,9% dos serviços respectivamente. Os autores discutem o significado das modificações verificadas no segmento privado da atenção à saúde de Salvador, bem como as implicações desses achados no que diz respeito ao redimensionamento das estratégias de reorganização das práticas e serviços de saúde no País e de relacionamento entre o público e o privado.To study the organization of private health services in the city of Salvador, Bahia, Brazil, a survey was carried out in 1994 involving 174 facilities registered at the Brazilian Institute of Statistics and Geography ­ IBGE. Health services characteristics studied were the following: number of physicians, hospital beds, production and cost of outpatient services, and legislative aspects. Health services were classified according to the amount of resources each type of granting agency contributed to support outpatient care. We found that the majority (51.1% of private health care services in Salvador do not depend on public funds. The main sources of revenue for health services are private health insurance (41.9% and other kinds of private health plans (54%. These changes in the organization of health services challenge

    Full Text Available Four weeks after Containment Vaccination undertaken against the largest outbreak of smallpox occured in Brazil in 1969, that of the municipality of Utinga, Bahia, 99 samples of serum were collected from the local population. These samples were classified in four groups: a - Individuals with a history of variola prior to the beginning of present outbreak in town (15 sera; "Previous smallpox group"; b - Individuals with primary vaccination, with no record variola, at the time of containment measures (15 sera. "Primary vaccinated group"; c - Individuals with no previous record of variola revaccinated with "take" at the time of containment (15 sera0, "Revaccinated group"; d - Individuals who contracted variola in present outbreak (54 sera these were subdivided in four sub-groups, according to dates on which cases ocurred, "Variola in outbreak group". Serological study of samples was done by tests of hemagglutination inhibition, neutralization, and complement fixation. It was observed that HI titers were significantly lower in cases of previous smallpox than in other groups. Although they were slightly higher on revaccinated individuals than on primary vaccinated group and than in the group of variola in outbreak, this difference was not significant. Those same antibodies were present in all cases of variola in outbreak, and it was found that titers decreased in direct proportion to time elapsed from occurrence of cases. Neutralizing antibodies proved to be significantly higher on the revaccinated group than on variola in outbreak group, and higher on these than on primary vaccinated and on the previous smallpox groups. In cases from the variola in outbreak it was verified that neutralizing antibodies remained stable, although with great variation in titers. Tests of complement fixation could not be undertaken on all samples, because many of them proved to have anticomplementarity. However, it was found that complement fixing antibodies diminished

    The scientific literature on teachers' health is scarce, recent, and focuses predominantly on stress and burnout. This study describes the labor conditions of private school teachers in Vitória da Conquista, Bahia State, Brazil. Information on 250 teachers from the ten largest schools in the municipality was collected through a self-applied questionnaire. The most relevant characteristics of teachers' work, evaluated by the Job Content Questionnaire were: speed of work, creativity at work, and relations with colleagues. The most frequent complaints related to posture, mental strain, and voice problems. Prevalence of minor psychological disorders according to the Self Reporting Questionnaire-20 was 41.5%, strongly associated with long periods of intense concentration on the same job and excessive work. Results suggest an association between the prevalence of minor psychological disorders and certain characteristics of teaching work, emphasizing teachers' exposure to stress.

    Antiretroviral therapy has significantly evolved in the last decade, with an increasing number of new drugs and classes. Currently, even heavily experienced patients can be successfully treated with new regimens. In Brazil, the recent incorporation of some new antiretroviral drugs made it possible to suppress HIV plasma viremia in most treated patients, with significant benefits in terms of quality of life and survival. However, little has been published on outcomes of patients under new drugs-based regimens. We reviewed the safety and efficacy of antiretroviral regimens using recently introduced drugs in Bahia. Our results confirm that patients using darunavir, raltegravir, enfuvirtide, or etravirine presented with a high rate of virological suppression without significant adverse events, after one year of follow-up.

    Full Text Available Abstract This study investigated the effects of tributyltin (TBT on the morphology of the genital system of the gastropod Stramonita rustica in southern Bahia, Brazil. For this, 330 specimens were collected during the summer of 2014 at eight sampling points to ascertain whether male sex organs had developed in addition to the complete female genital tract in females (= imposex. The analyses were made under a stereoscopic microscope. Imposex and their associated indexes, and the sterile females, exhibited the highest rates in harbors and shipyards areas. Despite the total ban of TBT in anti-fouling paints on a global scale since 2003, the results of this and other studies indicate the continued use of those paints on the Brazilian coast. This shows the inefficiency of existing legislation and the need to strengthen enforcement of the ban.

    Full Text Available In Brazil, current trends of the AIDS epidemic include an increase in transmission through heterosexual contact, predominantly from men to women, with more cases of AIDS in women and more children contaminated by vertical transmission. There is also a high proportion of cases in poor people or people living in small towns. HIV-infected patients with high levels of immunodeficiency are frequently hospitalized after their first visit to the clinic due to opportunistic infections, characteristic of advanced disease. This study characterized the clinical and laboratory pattern of AIDS in a sample of patients attended for the first time in the AIDS clinic of the Federal University of Bahia Hospital (HUPES in Salvador, Brazil. We revised medical charts of cases of subjects registered at the outpatient AIDS clinic from January 1997 to December 2003. The demographics, clinical data, and laboratory characteristics were analyzed to determine the degree of immunodeficiency at the time of admission. A total of 377 patients were evaluated (58.6% were male, with a mean sample age of 33.4 years. The most frequent clinical manifestations were asthenia, weight loss, fever, anemia, dermatitis, oral thrush and diarrhea. CDC criteria were not adequate to define the initial cases. After admission to the outpatient clinic, nearly 25% of the patients were hospitalized immediately, indicating delay in the diagnosis. In Bahia, the initial presentation of HIV-infected patients to health care assistance is occurring at a late stage of the disease, when signs and symptoms of immunodeficiency are already established. Efforts are necessary to construct strategies to make an early diagnosis of these patients, improve the quality of care, and guarantee the benefits of antiretroviral therapy, when it is indicated.

    We documented fruit fly-host associations and infestation rates over 5 yr in the state of Bahia, Brazil, by systematically collecting native and introduced fruits in backyard and commercial orchards, experimental stations, and patches of native vegetation. Fruit were collected in multiple sites in the southern and southernmost regions of Bahia. A total of 942.22 kg from 27 fruit species in 15 plant families was collected throughout this study. Of these, 15 plant species from six families were infested by Anastrepha species. A total of 11,614 fruit flies was reared from the fruit (5,178 females and 6,436 males). No specimens of Ceratitis capitata (Wiedemann) were recovered. Eleven Anastrepha species were recovered from the collected fruit: Anastrepha antunesi Lima (0.04%), Anastrepha distincta Greene (0.1%), Anastrepha fraterculus (Wiedemann) (53.5%), Anastrepha leptozona Hendel (4.5%), Anastrepha manihoti Lima (0.1%), Anastrepha montei Lima (1.0%), Anastrepha obliqua (Macquart) (33.0%), Anastrepha pickeli Lima (2.0%), Anastrepha serpentina (Wiedemann) (1.0%), Anastrepha sororcula Zucchi (3.0%), and Anastrepha zenildae Zucchi (1.8%). We recovered 1,265 parasitoids (Hymenoptera: Braconidae) from Anastrepha pupae. Three species of braconids were found to parasitize larvae of nine Anastrepha species. The most common parasitoid species recovered was Doryctobracon areolatus (Szépligeti) (81.7%), followed by Utetes anastrephae (Viereck) (12.2%) and Asobara anastrephae (Muesebeck) (6.1%). We report A. fraterculus infesting Malay apple Syzygium malaccense (L.) Merr. & L. M.

    Located in the Mucuri Basin on the continental shelf of southern Bahia state, northeast Brazil, about 70 km from the city of Caravelas,the Abrolhos archipelago is made up of five islands; Santa Barbara, Redonda, Siriba, Guarita and Sueste. The exhumed sediments in the Abrolhos archipelago are a rare record of the turbidite systems which fill the Brazilian Atlantic Basin, and are probably an unprecedented example of a plataform turbidite system (Dr. Mutti, personal communication). Despite the limited area, the outcrops display a wide facies variation produced by different depositional processes, and also allow for the observation of the layer geometries. Associated with such sedimentary rocks, the Abrolhos Volcanic Complex belongs stratigraphically to the Abrolhos Formation. These igneous rocks were dated by the Ar / Ar method, with ages ranging from 60 to 40 My, placing such Volcanic Complex between the Paleocene and Eocene. The sedimentary section is best exposed in the Santa Barbara and Redonda islands and altogether it is 70 m thick. The measured vertical sections show a good stratigraphic correlation between the rocks of the western portion of the first island and those of Redonda Island. However, there is no correlation between the eastern and western portions of Santa Barbara Island, since they are very likely interrupted by the igneous intrusion and possibly by faulting. The sedimentary stack consists of deposits with alternated regressive and transgressive episodes interpreted as high frequency sequences. The coarse facies, sandstones and conglomerates, with abrupt or erosive bases record regressive phases. On the other hand, finer sandstones and siltstones facies, which are partly bioturbated, correspond to phases of a little sediment supply. In the central and eastern portions of Santa Barbara Island, there is a trend of progradational stacking, while both in the western portion of Santa Barbara and in Redonda islands an agradational trend is observed

    Respiratory system is the major route of entry for airborne particulates, being the effect on the human organism dependent on chemical composition of the particles, exposure time and individual susceptibility. Airborne particulate trace metals are considered to represent a health hazard since they may be absorbed into human lung tissues during breathing. Fossil fuel and wood combustion, as well as waste incineration and industrial processes, are the main anthropic sources of metals to the atmosphere. In urban areas, vehicular emissions—and dust resuspension associated to road traffic—become the most important manmade source. This work investigated the atmospheric concentrations of TSP, PM 10 and elements such as iron, manganese, copper and zinc, from three different sites around Salvador Region (Bahia, Brazil), namely: (i) Lapa Bus Station, strongly impacted by heavy-duty diesel vehicles; (ii) Aratu harbor, impacted by an intense movement of goods, including metal ores and concentrates and near industrial centers and; (iii) Bananeira Village located on Maré Island, a non-vehicle-influenced site, with activities such as handcraft work and fishery, although placed near the port. Results have pointed out that TSP concentrations ranged between 16.9 (Bananeira) and 354.0 μg m -3 (Aratu#1), while for PM 10 they ranged between 30.9 and 393.0 μg m -3, both in the Lapa Bus Station. Iron was the major element in both Lapa Station and Aratu (#1 and #2), with average concentrations in the PM 10 samples of 148.9, 79.6 and 205.0 ng m -3, respectively. Zinc, on the other hand, was predominant in samples from Bananeira, with an average concentration of 145.0 ng m -3 in TSP samples, since no PM 10 sample was taken from this site. The main sources of iron in the Lapa Station and Aratu harbor were, respectively, soil resuspension by buses and discharge of solid granaries, as fertilizers and metal ores. On the other hand, zinc and copper in the bus station were mainly from

METHODS: We carried out a cross-sectional study in a group of 146 (292 eyes sickle cell disease patients (90 HBSS and 56 HBSC. Ophthalmologic examination including indirect binocular ophthalmoscopy was performed. Examination was completed by fluorescein angiography to detect retinal lesions. RESULTS: The most frequent ocular lesions identified were "vascular tortuosity" and "black sunburst". Proliferative retinopathy was found in 22 (12.2% eyes of HBSS patients and 25 (22.3% eyes of HBSC patients (OR=2.06; CI95%: 1.5-4.06, p=0.022; Its frequency was higher among HBSS patients aged 20-39 years, while in HBSC patients, it peaked after 40 years (35.7% and 42.8% and dropped sharply afterwards. CONCLUSION: Proliferative retinopathy was described as early as 10 years of age in both patients groups. Proliferative sickle retinopathy can result in blindness and the knowledge of the most prevalent ocular alterations and age risk will be important to establish a protocol of ophthalmologic follow-up, in order to prevent a severe visual loss and increase patient's life quality.OBJETIVO: O presente estudo teve como objetivo descrever as alterações oculares em pacientes portadores de doença falciforme, na Bahia, um estado do Nordeste, que tem a maior prevalência da doença no Brasil.

    Full Text Available Com o objetivo de descrever a distribuição espacial da mortalidade por tuberculose em Salvador nos anos de 1991, 1994 e 1997, foi realizado um estudo ecológico, descritivo, tendo como unidade de análise o Distrito Sanitário (DS. Foram calculados os coeficientes padronizados de mortalidade por tuberculose e a mortalidade proporcional por tuberculose, em relação ao conjunto das doenças infecciosas e parasitárias, utilizando-se as declarações de óbitos como fonte de dados. O DS com os maiores coeficientes padronizados foi o Subúrbio Ferroviário, com taxas de 15,7, 10,6 e 10,6/100 mil habitantes, em 1991, 1994 e 1997, respectivamente. Em 1997, foram observadas as menores taxas padronizadas. A mortalidade proporcional por tuberculose em Salvador, nos anos de 1991, 1994 e 1997, representou 20,7%, 18,2 % e 16,9%, respectivamente, do total das mortes por doenças infecciosas e parasitárias. A faixa etária de maior risco, nos anos estudados, foi aquela acima de 65 anos. Os autores discutem as possibilidades de utilização dos resultados deste estudo para a implementação de políticas locais de saúde equânimes e desenvolvimento de operações de vigilância da saúde, tendo em vista a identificação de DS com maior risco de óbito e as faixas etárias mais acometidas.An ecological study was conducted to describe the urban spatial distribution of mortality attributable to tuberculosis in Salvador, Bahia, Brazil in 1991, 1994, and 1997.

    Full Text Available Emission factors of anthropogenic activities and natural processes were used to estimate nutrients and metals loads to the Contas River lower basin, Southern Bahia, Brazil. Among natural sources, emission from soil leaching is larger for N, Cu and Pb. Atmospheric deposition is the major natural source of P, Zn, Cd and Hg. Among anthropogenic sources, agriculture is the major source of N, Cu and P. Urban sources are the major contributors to the other elements. Present anthropogenic land uses are already responsible for 78 and 99% of total N and P loads and about 50% of total Cu and Hg.

    Sarcocystis neurona is the major agent of equine protozoal myeloencephalitis. It infects several mammalian species in the Americas, where the definitive hosts, marsupials of the genus Didelphis (D. virginiana and D. albiventris) are found. Domestic cats are one of the confirmed intermediate hosts of the parasite; however, antibodies against S. neurona had never before been demonstrated in Brazilian cats. The aim of this study was to determine whether cats in Bahia, Brazil, are exposed to the parasite. A total of 272 feline serum samples (134 from feral and 138 from house cats) were subjected to an indirect fluorescent antibody test using cultured merozoites of S. neurona as antigen. Positivity was detected in 4.0% (11/272) of the tested samples, with titers ranging from 25 to 800. The feline sera were also tested for antibodies against the protozoan Neospora caninum, with an observed antibody frequency of 2.9%. To the author's knowledge, this is the first study to report antibodies against S. neurona in Brazilian cats. We conclude that cats are exposed to the parasite in the region of this study. Further investigations are needed to confirm the role of cats in the transmission cycle of S. neurona in Brazil.

    Full Text Available ABSTRACT: The semiarid region of Brazil holds a great richness of medicinal and aromatic plants with considerable potential for pharmaceutical, food, cosmetic and biopesticide industries. Martianthus leucocephalus (Mart. Ex Benth. J. F. B. Pastore is endemic to this region, and its essential oils contain a principle compound, isobornyl formate, which demonstrates antimicrobial activity against Bacilus cereus, Staphylococcus aureus and Candida albicans. In spite of its significant pharmacological potential, little is known about its growth. In light of the influence of seasonality on plant growth, development, and secondary metabolism, the present study evaluated the growth and essential oil content of M. leucocephalus grown and harvested during different months of the year in the edaphoclimatic conditions of Feira de Santana, Bahia State, Brazil. The experimental design was entirely randomized, with twelve harvesting periods and five replicates. The study acquired monthly data of mean temperatures, relative humidity, rainfall, irradiance, and photoperiod from the National Institute of Meteorology (INMET and quantified the fresh and dry weights of leaves, flowers and branches, as well as leaf area, and essential oil content. The data were submitted to Spearman correlation analysis and the means were compared using the Scott-Knott test. Total leaf masses and oil contents were higher during periods with longer photoperiods and higher solar irradiance. Rainfall and relative humidity reduced plant growth and essential oil content. Higher total mean dry masses were recorded from September to January (except October, while oil content was higher in March.

    Elemental analysis and isotopic composition evaluated the impact of human activity at the surface sediments in the largest island of Todos os Santos Bay, northeastern Brazil. Saturated hydrocarbons (n-alkanes and isoprenoids) by gas chromatography coupled with a flame ionization detector and (13)C by mass spectrometer were determined from 30 surface sediment samples in mangroves at the Itaparica Island (Bahia-Brazil) in the rainy and dry season. These data, distribution, and ratio of carbon/nitrogen showed a mixture of sources: continental, marine, and anthropogenic ones. From the chromatographic profiles, light oil contamination was observed in the dry regions of Baiacu, Campinas, and Ponta Grossa, while in Jiribatuba it was observed during the rainy season. However, δ(13)C results during dry and rainy season in the presence of oil also showed in Misericordia and Cacha Prego districts for both periods and Ponta Grossa during the rainy season. Principal component analysis, using a correlation matrix, revealed the latent relationships among all the surface sediment stations investigated and confirmed our analytical results.

    Full Text Available Maize is among the most important crops in the world. This plant species can be colonized by diazotrophic bacteria able to convert atmospheric N into ammonium under natural conditions. This study aimed to investigate the effect of inoculation of the diazotrophic bacterium Herbaspirillum seropedicae (ZAE94 and isolate new strains of plant growth-promoting bacteria in maize grown in Vitória da Conquista, Bahia, Brazil. The study was conducted in a greenhouse at the Experimental Area of the Universidade Estadual do Sudoeste da Bahia. Inoculation was performed with peat substrate, with and without inoculation containing strain ZAE94 of H. seropedicae and four rates of N, in the form of ammonium sulfate (0, 60, 100, and 140 kg ha-1 N. After 45 days, plant height, dry matter accumulation in shoots, percentage of N, and total N (NTotal were evaluated. The bacteria were isolated from root and shoot fragments of the absolute control; the technique of the most probable number and identification of bacteria were used. The new isolates were physiologically characterized for production of indole acetic acid (IAA and nitrogenase activity. We obtained 30 isolates from maize plants. Inoculation with strain ZAE94 promoted an increase of 14.3 % in shoot dry mass and of 44.3 % in NTotal when associated with the rate 60 kg ha-1 N. The strains N11 and N13 performed best with regard to IAA production and J06, J08, J10, and N15 stood out in acetylene reduction activity, demonstrating potential for inoculation of maize.

    Full Text Available PURPOSE: To carry out a study of association between socioeconomic and demographic factors and homicides in general population, in the state of Bahia, in 2009. METHODS: This is an ecological study. The data were collected from the database of the Information System about Mortality of the Ministry of Health, from the Brazilian Institute of Geography and Statistics and the Institute of Applied Economic Research. The Global Moran index was calculated for the detection of spatial autocorrelation, and the Local Moran index was calculated for the detection of spatial Clusters. The transformation in the variable answer (homicides rates was performed and it was shaped using the Conditional Autoregressive Model. RESULTS: The data showed spatial autocorrelation. Two clusters of municipalities with high rates of homicides were identified, one located predominantly in the Greater Metropolitan Region of Salvador and the other in the South Region of Bahia, especially Eunápolis and Lauro de Freitas, which had the highest rates. The Average Residents Variables, local GDP and the Percentage of Illiteracy presented an inverse association with homicide rates, and the variables Firjan's municipal development index of work and income. Enrolment in high school and the Average of Bolsa Família were directly associated. CONCLUSIONS: The urbanization process, in most cases, not controlled by the State, in most cases, made the cities bigger and with better socioeconomic conditions, attraction centers for people with different socioeconomic levels, increasing the social inequality among the residents of these regions, with parallel increase in homicide rates.

    Resumo. As palmeiras desempenham papéis importantes como habitats de reprodução e alimentação para triatomíneos silvestres, vetores da doença de Chagas. A ocorrência de triatomíneos em palmeiras peridomiciliares pode aumentar o risco de invasão desses insetos em domicílios e deve ser considerada para desenvolver estratégias de prevenção. Com objetivo de investigar a infestação de palmeiras por triatomíneos no Estado da Bahia e determinar a infecção natural desses insetos por Trypanosoma spp., foram amostradas 183 palmeiras em 12 municípios entre 2006 e 2011 utilizando captura manual e/ou armadilhas adesivas iscadas com camundongos. Os triatomíneos foram detectados em 79 palmeiras (43% das espécies Copernicia prunifera (Mart. Becc., Mauritia flexuosa L. e Attalea spp. (Attalea burretiana Bondar ou Attalea salvadorensis Glassman. Em outras espécies de palmeiras (Syagrus coronata (Mill H.E. Moore, Attalea funifera Mart ex. Spreng e Elaeis guineensis Jacq não foram detectados triatomíneos. Rhodnius neglectus Lent, Triatoma sordida (Stål, e Triatoma pseudomaculata Corrêa & Espínola ocorreram em C. prunifera ao longo do rio São Francisco. No extremo oeste da Bahia, R. neglectus e Psammolestes tertius Lent & Jurberg foram detectados em M. flexuosa, enquanto Triatoma tibiamaculata (Pinto ocorreu em Attalea sp. em áreas urbanas de Salvador. No total, 180 triatomíneos foram capturados, principalmente R. neglectus. A maior taxa de infecção natural (61% foi observada em T. tibiamaculata. Os resultados indicam que pelo menos três espécies de palmeiras são habitats favoráveis para triatomíneos no estado da Bahia e ocorrem no ambiente peridomiciliar, o que pode aumentar a probabilidade de invasão de triatomíneos nas casas.

    Full Text Available The characteristics of the quality of crude palm oil (CPO and crude palm olein (CPOL produced in the states of Bahia and Pará were investigated. Twelve oil samples were analyzed; 2 (CPO were from Pará (produced industrially, while the other 10 were from Bahia (3 CPOs and 3 CPOLs produced industrially, while 1 CPOL and 3 CPOs were traditionally processed. The chemical analyses included the determination of fatty acid methyl esters (FAME, free fatty acids (FFA%, peroxide value (PV, induction time (IT, total carotenoids (TC and total polar compounds (TPC. The major saturated fatty acids in these samples were palmitic (34.79-42.89 g 100 g–1 and stearic (4.49-5.84 g 100 g–1 acid, and the main unsaturated fatty acids were oleic (37.31-43.69 g 100 g–1 and linoleic (9.04- 12.74 g100 g–1 acid. All samples produced in Bahia exhibited higher FFA (6.77-13.49% and TPC (13.71-19.50% levels than permitted in the international quality standards, unlike the samples produced in Pará. TC, PV and IT ranged from 422.1 to 584.2 mg g–1, 1.32 to 3.7 meq O2 kg–1 oil and 1.72 to 4.66 h, respectively. PV, FFA and TPC were inversely correlated with TC and IT. The use of inappropriate oil extraction processes in Bahia is clearly becoming a food safety problem.Las características de calidad del aceite de palma crudo (CPO y oleína de palma cruda (CPOL producidos en los estados de Bahía y Pará fueron investigados.

    Full Text Available OBJECTIVE: To study patterns of alcohol consumption and prevalence of high-risk drinking. METHODS: A household survey was carried out in a sample of 2,302 adults in Salvador, Brazil. Cases of High-Risk Drinking (HRD were defined as those subjects who referred daily or weekly binge drinking plus episodes of drunkenness and those who reported any use of alcoholic beverages but with frequent drunkenness (at least once a week. RESULTS: Fifty-six per cent of the sample acknowledged drinking alcoholic beverages. Overall consumption was significantly related with gender (male, marital status (single, migration (non-migrant, better educated (college level, and social class (upper. No significant differences were found regarding ethnicity, except for cachaça (Brazilian sugarcane liquor and other distilled beverages. Overall 12-month prevalence of high-risk drinking was 7%, six times more prevalent among males than females (almost 13% compared to 2.4%. A positive association of HRD prevalence with education and social class was found. No overall relationship was found between ethnicity and HRD. Male gender and higher socioeconomic status were associated with increased odds of HRD. Two-way stratified analyses yielded consistent gender effects throughout all strata of independent variables. CONCLUSIONS: The findings suggest that social and cultural elements determine local patterns of alcohol-drinking behavior. Additional research on long-term and differential effects of gender, ethnicity, and social class on alcohol use and misuse is needed in order to explain their role as sources of social health inequities.OBJETIVOS: Investigar padrões de consumo de álcool e prevalência de consumo de alto risco.

    Full Text Available “Restingas” are herbaceous/ shrubby coastal sand-dune habitats that cover great areas of Brazil, particularly along the Bahia state coast. The restingas are disturbed and are under strong pressure, mainly in northeastern Brazil. Fragmentation of the landscape and habitat loss within natural ecosystems are the factors which are mainly responsible for reduction of species diversity by extinction events. The goal of thepresent study was elucidate whether the conservation status of restinga habitats on the northern coast of Bahia state was interfering with microhabitat use by the endemic lizard Tropidurus hygomi. The results showed that the use of microhabitat resources by T. hygomi did not have any signifi cant differences in the four areas we chose for study. However, diverse factors of degradation were found to contribute indirectly to its habitat loss. The T. hygomi lizard is a generalist in its use of restinga microhabitats, and probably due the endemic condition, its conservation status is linked directly to conservation of the restinga habitats on the northern coast of Bahia state.

In 1999, we assessed sociodemographic variables and family environment characteristics. In 2001, we used the Child Behavior Checklist to measure and describe the frequencies of behavior problems. We conducted bivariate and multivariate analysis to estimate associations between family and maternal factors and prevalence of behavior problems.Results:The overall prevalence of behavior problems was 23.5%. The prevalence of internalizing problems was 9.7%, and that of externalizing problems, 25.2%. Behavior problems were associated with several maternal mental health variables, namely: presence of at least one psychiatric diagnosis (odds radio [OR] 3.01, 95%CI 1.75-5.18, anxiety disorder (OR 2.06, 95%CI 1.20-3.46, affective disorder (OR 2.10, 95%CI 1.21-3.65, and mental health disorders due to use of psychoactive substances (OR 2.31, 95%CI 1.18-4.55.Conclusion:The observed prevalence of child behavior problems fell within the range reported in previous studies. Maternal mental health is an important risk factor for behavior problems in preschool-aged children.

    Leaf-cutting ants interact with several fungi in addition to the fungal symbiont they cultivate for food. Here, we assessed alien fungal communities in colonies of Atta cephalotes. Fungus garden fragments were sampled from colonies in the Atlantic Rainforest and in a cabruca agrosystem in the state of Bahia (Brazil) in two distinct periods to evaluate whether differences in nest habitat influence the diversity of fungi in the ant colonies. We recovered a total of 403 alien fungi isolates from 628 garden fragments. The prevalent taxa found in these samples were Escovopsis sp. (26 %), Escovopsioides nivea (24 %), and Trichoderma spirale (10.9 %). Fungal diversity was similar between the colonies sampled in both areas suggesting that ants focus on reducing loads of alien fungi in the fungus gardens instead of avoiding specific fungi. However, fungal taxa composition differed between colonies sampled in the two areas and between the sampling periods. These differences are likely explained by the availability of plant substrates available for foraging over habitats and periods. Ordination analysis further supported that sampling period was the main attribute for community structuring but also revealed that additional factors may explain the structuring of fungal communities in colonies of A. cephalotes.

    A cross-sectional study with all the teachers in the municipal school system in Vitória da Conquista, Bahia State, Brazil, investigated the association between work content (psychological demand and control over work) and the occurrence of minor psychiatric disorders (MPD) among teachers. The Karasek demand-control model was used to evaluate control over work. The Self-Report Questionnaire-20 was used to evaluate minor psychiatric disorders. MPD prevalence was 55.9% among the 808 teachers studied. Crude prevalence of MPD showed a positive and significant association with psychological demand and a negative and significant association with control over work. MPD prevalence was higher in teachers with highly demanding work, characterized by heavy demand and low control (PR = 1.74; 95%CI: 1.44-2.10), and in those with active work, with heavy demand and low control (PR = 1.35; 95%CI: 1.13-1.61), as compared to teachers with low-demand work (light demand and high control), after adjusting for confounders in a multiple logistic regression model. As a conclusion, teachers' mental health is strongly associated with their work content.

    Fábio David Couto

    Full Text Available The C677T polymorphism in the methylenetetrahydrofolate reductase gene (MTHFR is associated with an increase in total homocysteine serum levels (tHcy, described as a risk factor for cardiovascular disease. Eight hundred forty-three neonates from two different maternity hospitals, one public and another private, in Salvador, Bahia, Brazil were screened for this polymorphism by PCR and RFLP. The T-allele frequency in the total sample was 0.23, and the prevalence rates of heterozygous and homozygous carriers were 36.2% and 5.3%, respectively. The T-allele frequency differed and the T/T genotype was more prevalent at the private maternity hospital. The hemoglobin (Hb profile was investigated by HPLC in 763 newborns. The frequency of variant Hb was higher at the public than at the private maternity hospital. The association of the C677T polymorphism and the Hb profile was investigated in 683 newborns, showing a relatively high frequency of variant Hbs and the T allele. These data could provide an important basis for further studies focusing on potential risks of vaso-occlusive events in these individuals.

    Trace elements concentrations (As, Ba, Cd, Cr, Cu, Ni, Pb, V and Zn) were found in samples of Halodule wrightii Aschers (Cymodoceaceae) seagrass from Todos os Santos Bay, Bahia, Brazil by inductively coupled plasma mass spectrometry (ICP-MS). This bay has been impacted by the presence of industrial activity that includes chemical and petrochemical plants as well as an oil refinery and harbor activities located in the north and northeastern area. Samples were collected at 4 stations to evaluate the distribution of element concentrations in this area and under different climatic conditions. The mean concentrations, in mgkg(-1), found in dry tissues for all the studied metals and stations were: As (1.08-5.42), Ba (3.72-32.0), Cd (0.135-1.68), Cr (1.15-10.4), Cu (2.23-13.4), Ni (1.95-9.87), Pb (0.873-5.18), V (3.39-22.4) and Zn (13.1-39.5). Statistical analysis (ANOVA) of the seagrass data showed significant inter-site differences for all elements examined except nickel and vanadium. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Aiming at contributing to the knowledge of physical factors affecting community structure in Atlantic Forest remnants of southern Bahia state, Brazil, we analyzed the annual variation in the understory microclimate of a hillside forest fragment in the ‘Reserva Particular do Patrimônio Natural Serra do Teimoso’ (RST and a rustic cacao agroforestry system (Cabruca, located nearby the RST. Canopy openness (CO, air temperature (Ta, air relative humidity (RH and vapor pressure deficit (VPD data were collected between April, 2005 and April, 2006 at the base (RSTB, 340 m and the top (RSTT, 640 m of the RST and at the Cabruca (CB, 250 m. Data of rainfall, Ta, RH and VPD were also collected in an open area (OA, 270 m. The highest rainfalls (> 100 mm occurred in November, 2005 and April, 2006, whereas October, 2005 was the driest month (< 20 mm. CO ranged between 2.5 % in the CB (April, 2006 and 7.7 % in the RST (October, 2005. Low rainfall in October, 2005 affected VPDmax in all sites. Those effects were more pronounced in OA, followed by CB, RSTB and RSTT. During the period of measurements, the values of Ta, RH and VPD in CB were closer to the values measured in OA than to the values measured inside the forest.

    This paper deals with the semiotic meanings which are given both to the appearance and/or behavior of insect species according to the ethnoentomological knowledge of the inhabitants of the village of Pedra Branca, Bahia State, Brazil. Data were collected from February to May 2001 by performing open-ended, recorded interviews with nine men and twenty-five women, whose ages ranged from 19 to 82 years old. Data were analyzed by using the union model, which involves considering all available information on the surveyed subject. Twelve kinds of insects were associated with both beneficial and harmful events, as well as with the indication of changing weather. The way local people perceive and interpret the appearance and/or behavior of certain species of insects depends on the cultural background of each inhabitant. The following semiotic meanings were recorded: fatal, funereal, auspicial, meteorological, societal, monetary, and of abundance or scarcity. The beliefs in the augural power of insects in the village of Pedra Branca are deep-rooted in the local tradition and are transmitted from generation to generation through oral culture. It is hoped that the data now available will be incorporated into a curriculum by those researchers interested in insect conservation and ethnobiology as well.

    This paper reports on the first occurrence of Psammolestes tertius in the Chapada Diamantina region, located in the city of Seabra, Bahia State, in northeastern Brazil. Following an active search, 24 P. tertius specimens were collected from Phacellodomus rufifrons (rufous-fronted thornbird) nests. The insects did not present any symptoms of infection by Trypanosoma cruzi. P. tertius males were cytogenetically analyzed, and the results were compared with those of other specimens from the Brazilian State of Ceará. Triatomines from both locations presented the same cytogenetic characteristics: 22 chromosomes, little variation in the size of the autosomes, Y chromosomes that were larger than the X chromosomes, a chromocenter formed only by the sex chromosomes during prophase, and autosomes lacking constitutive heterochromatin. However, it is important to note that this species shows intraspecific chromosomal variation. In light of the results obtained, it is recommended that more studies be performed to characterize P. tertius. These studies will be particularly helpful in understanding this species in ecological, biological, biogeographical, and phylogenetic terms.

    Full Text Available Few studies have registered signs of mutilation on cetaceans in Brazil, especially from shark attacks. This work describes interactions between cookiecutter sharks Isistius spp. and cetaceans through the analysis of bite records for cetacean carcasses washed ashore on the Bahia coast between 1996 and 2005. Twenty bite records were analyzed in 13 cetacean species, of which the Delphinidae family was the most frequent. After the analysis, Isistius plutodus was identified as the aggressor species on 80% of the records, followed by I. brasiliensis (20%, based on the characteristic shape of the mutilations. The areas most subject to attack in cetaceans were: flanks 40%; head and abdomen 20% each; dorsal 15%; and genital with 5%. The relatively high number of bites on the flanks was probably due to its larger area, which offered greater opportunities to the cookiecutter shark. At least three bite records were related to the possible causes of strandings in delphinids. We recommend further studies on interactions between sharks and cetaceans along the Brazilian coast.

    Navigable inland waterways, including lakes, rivers, and reservoirs, are important transportation routes for people and goods in Brazil. Natural and anthropogenic effects coupled with recent severe droughts have led to decreased inland waterway navigation. The Company for Development of the São Francisco and Parnaíba River Valleys (CODEVASF) has recognized the decrease in waterway navigation and is investing resources to help restore selected reaches of the São Francisco River for navigation. In 2011, CODEVASF signed an agreement with the U.S. Army Corps of Engineers (USACE) seeking technical assistance and engineering expertise in waterway navigation and bank stabilization. The Torrinha-Itacoatiara study reach near Torrinha, Bahia was 1 of 12 conceptual waterway navigation improvement feasibility studies and was the focus of this study. The U.S. Geological Survey, in cooperation with the USACE and CODEVASF, collected topographic and hydrographic data from May 22 to June 12, 2014, to provide baseline data for supporting computational streamflow models.

    Full Text Available This study characterized the reproductive cycle of the stout razor clam Tagelus plebeius in the estuary of the Cachoeira River, Ilhéus, Bahia, northeastern Brazil. Samples of 20 animals per collection were taken biweekly from August 2005 to August 2006. The 480 specimens were measured on the antero-posterior axis (length and then removed from the shell. After macroscopic analysis, the gonads were fixed in Davidson's solution, processed by routine histology and stained by Harris hematoxylin and eosin. The gonads of both males and females appeared milky white, without sexual dimorphism. Microscopic analyses indicated a M: F ratio of 1.06: 1 and continuous reproduction of T. plebeius in the region. The period from August to October showed the most intense spawning. This study provides another example of continuous reproduction of bivalves in tropical waters, and because this species is a heavily exploited fishery resource in the region, it draws attention to the need for a management plan aimed at reducing harvests.

    Full Text Available A pilot experience of participatory monitoring and biological sampling realized by artisanal fishermen on-board their vessels was conducted between January 2011 and April 2012 in a Territory of Citizenship of Southern Bahia. The approach adopted aimed at including fishermen in the research process, valuing traditional knowledge and also ensuring the acquisition of biological data of difficult access on the spawning of reef fish caught in reproductive aggregation sites distant from the coast. The action was developed through the integration of collaborating fishermen within the research. Two masters of the artisanal handline fishing, recognized as experts in the communities of Valença and Camamu, have benefited from research grants by the state foundation for research supporting – FAPESB. The collaborating masters and crews of vessels were qualified and involved in the monitoring process, collecting information on-board about catches, fishing effort, exploited areas (fishing spots, biometrics and stages of sexual maturation. Monthly orientation and monitoring supervision of collaborating fishermen were conducted by researchers and technicians from the State University of Feira de Santana (UEFS and the agricultural development agency of Bahia state (EBDA. A total of 56 handline fishing operations from 24 fishing spots were monitored; 26 taxa were recorded during these fisheries, 3,271 fishes were measured and weighed, and 149 gonads were collected. The evaluation of the approach was based on qualitative parameters: 1 engagement and collaboration in the activity, 2 efficiency and consistency in data collection, filling out the forms and classification of gonads. The main challenge of the proposed approach is the perception of the fishermen about the relevance of participatory monitoring to promote the construction of knowledge about the fishery and the reproductive dynamics of fisheries resources. A continuous action is considered essential to

    Full Text Available Direct diagnoses were made by using - blood smears and nested PCR (nPCR tests on 309 blood samples from crossbred dairy cattle in the municipality of Ibicaraí, Bahia. From diagnostic blood smear slides, the observed parasitic frequencies were 31.1% for Anaplasma marginale and 20.4% for Babesia sp. From nPCR diagnoses, they were 63% for A. marginale, 34% for Babesia bigemina and 20.4% for Babesia bovis. There were significant differences (P <0.01 between the two diagnostic methods (nPCR and blood smear slides. The compliance obtained from the kappa test was 0.41 and 0.48 for A. marginale and Babesia sp., respectively. The tick samples from the six farms analyzed using nPCR were only positive for A. marginale. Evaluation of the risk factors relating to the presence of ticks and the age of the animals showed that there was a significant association (P <0.01 with the frequency of animals infected with both pathogens. Therefore, under the conditions studied, nPCR proved to be a good tool for diagnosing the agents of the bovine babesiosis and anaplasmosis complex because of its sensitivity and specificity in comparison with blood smears. The municipality of Ibicaraí is an area with endemic prevalence of bovine babesiosis and anaplasmosis confirmed by nPCR and A. marginale is the main agent of the disease.

    2014-09-01

    This article analyzes the process of government planning in health in the state of Bahia in the 2007-2010 period based on the formulation of the State Health Plan. The benchmark adopted involved adaptation of the theoretical model of the cycle of public policy, including analysis of context, characterization of the actors involved, operations conducted in decision making and the strategic means used. The production of information was through the analysis of documents organized in institutional portfolios and records of the planning process in the organization studied. The analysis of results reveals that the political game included "concessions" and "negotiations" regarding changes in the management and organization of the health system, highlighting the discussion on the problems facing the state management of the Unified Health System (SUS) during the period, and the search for alternatives and solutions to these problems. It also reveals the institutional learning acquired, involving managers and technicians who broadened and reinforced their capacity to analyze and formulate proposals around the government agenda.

    The origin of diamonds from Serra do Espinhaço in Diamantina region (State of Minas Gerais) and in Chapada Diamantina, Lençóis region (State of Bahia) remains uncertain, even taking into account the ample research carried out during the last decades. The lack of typical satellite minerals in both districts makes a kimberlitic source for these diamonds uncertain. In mid 18th century the occurrence of a metamorphosed igneous rock composed of martite, sericite and tourmaline was described in Diamantina region and named hematitic phyllite, considered by some researchers as a possible diamond source. Similar rocks were found in Lençóis and examined petrographically and their heavy mineral concentration was investigated by means of scanning electron microscopy (SEM). Petrographic analyses indicated an igneous origin for these rocks and SEM analyses showed the discovery of microdiamonds. Geochronological studies using the Ar/Ar technique in muscovites yielded minimum ages of 1515+/-3 Ma, which may correlate with 1710+/-12 Ma from U-Pb method in igneous zircons from the hematitic phyllites. Both rock types also have the same mineral and chemical composition which leads to the conclusion that the intrusive rocks were protolith of the hematitic phyllites. This first discovery of microdiamonds in intrusive rocks opens the possibility of new investigation models for diamond mineralization in Brazilian Proterozoic terrains.

    Full Text Available O presente estudo, reunindo uma vertente epidemiológica e uma vertente antropológica, permitiu evidenciar os significados sociais subjacentes a dados indicados pela comparação do monitoramento de diferenciais da distribuição das taxas de mortalidade por homicídios em um bairro de Salvador, realizados em dois períodos: o primeiro situado entre 1988 e 1994 e o segundo, entre 1994 e 2000. O estudo etnográfico indicou que, no primeiro período, ocorreu o extermínio de muitas pessoas consideradas delinqüentes e o assassinato de muitos moradores no bairro, o que, no estudo epidemiológico, corresponde a um aumento na taxa de mortalidade por causas externas. Já entre 91-94, observa-se um decréscimo na taxa de mortalidade, coincidindo, no trabalho de campo, com o período considerado de "acalmia". Na segunda metade da década de noventa, observa-se um novo aumento da taxa de homicídios na área de estudo, embora os moradores revelem uma imagem pacífica do bairro. O presente estudo realiza uma hermenêutica da violência nesse bairro, especialmente dos atos de extermínio, e das dinâmicas sociais que a envolviam nos seus diversos períodos.The present study, including an epidemiological and anthropological approach, highlighted the social meanings involved in the comparison of mortality rates from homicide in a neighborhood in Salvador, Bahia, Brazil, during two periods: 1988-1994 and 1994-2000. The ethnographic study showed that from 1988 to 1991, many neighborhood residents had been assassinated and numerous individuals labeled as delinquents had been "wiped out" (through summary executions, thus accounting for the proportional increase in mortality from external causes evidenced in the epidemiological study. The succeeding periods correspond to a decrease in mortality rates which (as evidenced by fieldwork coincided with a "lull" immediately afterwards. However, in the latter half of the 1990s a new increase in mortality rates was

    Lucas Dias

    Full Text Available Paracoccidioidomycosis (PCM cannot always be diagnosed by conventional means such as direct examination of histopathology or clinical samples, and serological methods, used as an alternative, still have many cases of cross-reactivity. In this scenario, molecular techniques seem to arise as a rapid approach, specific and direct that could be used in the diagnosis of this mycosis. In this study we analyzed 76 serum samples from patients in southern Bahia suspected of having paracoccidioidomycosis using a conventional PCR with primers for the ITS1 ribosomal DNA of P. brasiliensis. Of these 76 patients, 5 were positive for PCM by double immunodiffusion and/or direct examination and histopathology. To test specificity of PCR, we used human DNA and three isolates of P. lutzii (1578, 01 and ED01. Additionally, we analyzed by serial dilutions of DNA the limit of detection of the assay. The test of PCR proved specific, as only a 144 bp fragment of the three isolates of P. lutzii and no human DNA was amplified. Detection limit was 1.1 pg/µL of DNA. Despite the high detection limit and specificity of PCR none of the 76 serum samples were found positive by PCR, but a biopsy specimen obtained from one of the patients with PCM was positive. These results, albeit limited, show that PCR is not effective in detecting DNA of P. brasiliensis or P. lutzii in serum, but could perhaps be used with other types of clinical samples, especially in those instances in which conventional methods fail.

    Sarcocystis spp. are cyst-forming coccidia that infect numerous animals species, including several livestock species. Despite the importance of sheep and goat production in Brazil, little it is known about the Sarcocystis species that infect small ruminants in the country and their potential impact on meat condemnation due to the presence of macroscopic cysts of the parasite. The aims of the present study were to determine the frequency of infection by Sarcocystis spp. in goats and sheep intended for human consumption in Bahia State, Brazil, as well as to identify the parasite species in selected samples. The entire tongue, esophagus, and heart were collected from 120 goats and 120 sheep. Tissues were examined for Sarcocystis spp. by macroscopic evaluation, light microscopy, electron microscopy, and molecular tests. Microscopic cysts of Sarcocystis spp. were detected in 95.8 % of sheep and 91.6 % of goats. Using either transmission electron microscopy or partial sequencing of the 18S region of the ribosomal DNA (rDNA) for species identification, Sarcocystis tenella and Sarcocystis arieticanis were observed in sheep and Sarcocystis capracanis in goats. Macroscopic cysts were not detected in the analyzed samples. We concluded that goats and sheep destined for human consumption in Bahia possess high frequencies of Sarcocystis infection. Carcass condemnation due to Sarcocystis macrocysts seems to be rare in the studied region. S. arieticanis and S. capracanis were confirmed for the first time by electron microscopy or by molecular tests in small ruminants from Brazil.

    Kaolinitic clays are vastly used in ceramic industry. Light coloration burned clays are very useful in the coatings production because of their aesthetic. In this work clay material from Vitoria da Conquista (south-west Bahia, Brazil) was characterized by various techniques. Differential Scanning Calorimetry (DSC) shows a kaolinite characteristic curve with an endothermic peak at 492 deg C, which corresponds to the kaolinite - metakaolinite transformation. Transformation alpha to beta quartz is characterized by a 573 deg C peak. The samples were also characterized by water absorption and x rays powder diffraction. The 1100 deg C burned samples were tested by rupture tension with acceptable results. (author)

    A study about the horizontal stratification of the sand fly fauna in two distinct ecosystems, caatinga area, endemic for visceral leishmaniasis, and the tropical rain forest area, endemic for cutaneous leishmaniasis, was performed in the state of Bahia, Brazil. Lutzomyia longipalpis was predominant in the caatinga, and following it came the species L. capixaba and L. oswaldoi. In the tropical rain forest other species were found, such as L. intermedia, L. migonei, L. whitmani, L. yuilli, L.fischeri, L. damascenoi, L. evandroi, L. monticola, and L. lenti. It was found that the geographical limits of the vector species of visceral and cutaneous leishmaniasis are clearly defined by the biological and phytogeographic characteristics.

    Karst aquifers are important freshwater resources for the growing population in Brazil. The sandstones of Urucuia plateau and the limestone of Bambui Group constitute important aquifer systems in the western part of Bahia state. The Corrente River provides ∼30% of the total water flow of the São Francisco River and crosses karstified structures. Surface and groundwater samples were collected during the dry period, the beginning of the wet season, and the wet season. The main objective was to define sources and distribution of dissolved elements and to describe the geochemical processes that govern their mobility within the system. Water samples are classified into three groups, depending on the dominant weathering process. When carbonate dissolution governs, waters are bicarbonate-calcium-type; whereas when the atmospheric precipitation signal is present, the samples in siliciclastic terrain are more Cl- - Na+. Groundwaters reflect bicarbonate-mixed-type, with the highest dissolved concentrations. In contrast to the major elements, trace elements, including Rare Earth Elements (REE), show seasonal behavior: their concentrations increase with the beginning of the wet season, due to re-mobilization and release into the solution of adsorbed elements from the system and the atmospheric dust. The total dissolved REE concentration (800-7500 ng L-1) is one order of magnitude more concentrated in karsts than in siliciclastic rocks. Principal component analysis was performed, explaining >77% of the variance. First factor extracted (REE, Y, Th, Al, Fe) explain the washout and enhancement of atmospheric dust weathering throughout the beginning of the wet seasons. The second component comprises variables related to karsts lithology, representing calcite and dolomite dissolution.

    Full Text Available Freshwater crabs are important elements in the aquatic biota of brooks, rivers, lakes and ponds, from both ecological and the socio-economic aspects. Trichodactylidae comprises 51 endemic species from the Neotropical region. Among all the species of this family, Trichodactylus fluviatilis Latreille, 1828 has the widest geographic distribution throughout Brazil. Despite that, there are few published contributions on the biology of this species. The present study investigated the following aspects of T. fluviatilis: relative growth, mean size at onset of morphometric maturity, sexual dimorphism, laterality and heterochely. Specimens were collected monthly from September 2010 through August 2011, from the Velha Eugênia Brook, municipality of Santa Teresinha, State of Bahia. Carapace width (CW, carapace length (CL, major cheliped length (MaCL and minor cheliped length (MiCL, major cheliped height (MaCH and minor cheliped height (MiCH, and width of the fifth abdominal segment (5AB were measured to evaluate the presence of sexual dimorphism; the major difference between the sexes was in the CW vs. 5AB ratio. Heterochely was observed in males and females,with the right cheliped larger than the left in 89% of males and 81% of females. Crab size at the onset of morphometric maturity (= puberty molt was estimated based on the ratio between CL, cheliped dimensions, 5AB and CW (independent variable. Females were larger than males when they reached morphometric maturity in all studied relations. We recommend the use of chelipeds and abdominal width relationships to estimate the size at the morphometric maturity in males and females, respectively.

    Full Text Available Local Ecological and Taxonomic Knowledge (LEK of fish held by fishermen in the municipality of Ilhéus, Bahia, Brazil, known as the snapper ("vermelho" was examined from August 2005 to November 2006. Semi-structured interviews and tests were made with fishermen selected under the criteria of "specialists". The data analysis followed the union model of the different individual competences. Grouping analysis was performed on data referring to the localities of the occurrence of these fish, depth, coloration, and morphological characteristics of the species using the Pearson correlation coefficient (UPGMA. A total of 19 species were named within the snapper group, although three of them could not be scientifically identified. The Lutjanidae family presented the greatest numbers of species (n = 9. Other families mentioned were: the Serranidae (n = 3, Holocentridae (n = 2, Priacanthidae (n = 1, Mullidae (n = 1. The 1:1 correspondence between fishermen's local names and scientific species observed in this study indicates the richness of local fishermen knowledge. Analysis of the LEK related to the feeding habits of these fish and indicated that most were considered as being carnivorous, which agrees with the specialized literature consulted. In terms of their spatial distribution, two categories were detected: locality of occurrence (rivers/sea, coast, and offshore and depth (surface, mid-depth, mid-depth/deep, deep. The fish were considered locally to be "winter fish", based on harvested yields. Most of the interviewees knew little about the reproductive aspects of these fish. The main criteria used to identify, name, and classify the species were based on color and morphological aspects. Much of the information gathered in this study agreed with the published literature, which strengthens the importance of including LEK in planning and decision-making processes.

    The uraniferous district of Lagoa Real, located in the south-central region of the state of Bahia, has reserves estimated at 100,000 tons of uranium, which is enough to supply Angra I, II and III for 100 more years. The process adopted for the beneficiation of the uranium ore from Lagoa Real is heap leaching, a static process in which the ore is crushed, disposed in heaps and irrigated with a sulfuric acid solution to remove the uranium. This technique has a relatively low cost of implementation, although the yield of uranium recovery is low, with an uranium content in the leached residue of 700 {mu}g/g U{sub 3}O{sub 8} for ores with an initial content of 2,700 {mu}g/g U{sub 3}O{sub 8}. With the deepening of the mine pit, an increase in the carbonate content in the ore was noted, which required a higher acid consumption in the leaching. In order to reduce the concentration of carbonates, a study of the ore concentration by flotation column was accomplished. The flotation reject had high carbonate content, with a uranium content of about 2,300 {mu}g/g U{sub 3}O{sub 8} for flotation in one column and 1,100 {mu}g/g U{sub 3}O{sub 8} for flotation in two columns. This paper presents the study of the leaching process for the recovery of the uranium present in the residue of the heap leaching and in the carbonated residue from the flotation of the anomaly 13 ore. The results indicate the feasibility of treating the waste of the heap leaching through dynamic leaching. The study of the uranium leaching from the flotation residue through acid leaching technique indicated a recovery of 96% of uranium, however with a high consumption of acid, around 450 kg/t, showing that for this case, the most suitable technique for the process is alkaline leaching.

    Hemoglobinopathies are the most common genetic disorders in the world and include sickle cell anemia (SCA), which is a public health problem in Brazil. Nevertheless, the disease is highly unknown among health professionals, and delayed diagnosis constitutes an important cause of concern for caretakers of SCA patients. The purpose of this study was to compare the clinical and laboratory history of SCA patients whose diagnosis was established during the first year of life to those of other SCA patients who had delayed SCA diagnosis. Demographic, clinical, and laboratory data were all reviewed from 99 steady-state SCA patients who were followed in a public hematology and hemotherapy clinic in Salvador, Brazil. The patients were aged > or = 12 years and attended the outpatient unit at least once from November 2008 to June 2009. The data were analyzed in 2010. For all patients, the mean age (+/- SD) at diagnosis was 12.7(+/- 12.1) years, ranging from 0 to 47 years. Mean age was higher in patients whose SCA diagnosis was established after age 5 (32.9 +/- 11.9 years, P = .005). Increased unconjugated bilirubin, stroke and splenic sequestration were more prevalent in patients who were diagnosed in the first year of life (P = .043, .024 and .026 respectively). The data suggest that stroke, splenic sequestration and unconjugated bilirubin level may be influenced by age at SCA diagnosis.

    This study was conducted to link soil and litter microbial biomass and activity with soil and litter quality in the surface layer for different pure and mixed stands of native tree species in southeastern Bahia, Brazil. The purpose of the study was to see how strongly the differences among species and stands affect the microbiological attributes of the soil and to identify how microbial processes can be influenced by soil and litter quality. Soil and litter samples were collected from six pure and mixed stands of six hardwood species (Peltogyne angustifolia, Centrolobium robustum, Arapatiella psilophylla, Sclerolobium chrysophyllum, Cordia trichotoma, Macrolobium latifolium) native to the southeastern region of Bahia, Brazil. In plantations of native tree species in humid tropical regions, the immobilization efficiency of C and N by soil microbial biomass was strongly related to the chemical quality of the litter and to the organic matter quality of the soil. According to the variables analyzed, the mixed stand was similar to the natural forest and dissimilar to the pure stands. Litter microbial biomass represented a greater sink of C and N than soil microbial biomass and is an important contributor of resources to tropical soils having low C and N availability.

    This study determined the concentrations of major and trace elements in shellfish (oysters, clams and mussels) and conducted an assessment of the health risks due to the consumption of contaminated seafood. Samples were collected at 34 sites along Todos os Santos Bay, Brazil. The elements were determined by ICP OES and Hg by Direct Mercury Analysis. Relatively high concentrations of trace elements (As, Zn, Se and Cu) were found in seafood tissues. Potential daily intake of As, Co, Se, Zn and Cu associated to shellfish consumption suggested relevant non-carcinogenic risk for all studied locations. Copper was the element that posed the greatest non-carcinogenic risk, while Pb posed the highest carcinogenic risk. Health risks for humans were greatest from the consumption of mussels. Contaminated shellfish offer the greatest risk for children, subsistence fishers and subsistence shellfish consumers. Copyright © 2011 Elsevier Ltd. All rights reserved.

    There is little information about the congenital chikungunya virus (CHIKV) transmission. We describe two cases of well-documented congenital CHIKV infection in Salvador-Brazil, where CHIKV has been identified since 2014. The outbreak in the city led to the clinical CHIKV diagnoses of both pregnant women 2 days before delivery. Urine and blood samples from the mothers and newborns were collected and tested for reverse transcription-polymerase chain reaction (PCR) analysis for Zika, dengue, and CHIKV. Both neonates and mothers had positive urine and serum PCR results for CHIKV. The newborns had significant perinatal complications and were admitted to the neonatal intensive care unit. The purpose of our case report is to show how severe congenital CHIKV infection can be and the importance to include CHIKV infection in the differential diagnosis of neonatal sepsis when mothers have clinical signs of the disease and live in an affected area.

    Full Text Available The aim of this research is to show and describe the pacific transformation of Candeal neighborhood (Salvador de Bahía, Brazil, which evolved from a typical Brazilian favela towards a world reference social community. This analysis is based on the Imperfect peace approach, considering its implications on that transformation, and analyzing basic principles of Pacific Empowerment. This article is part of a complete and more comprehensive research, in which, due to the ethnographic analytical methodology, and the active observation, it was possible to interpret and understand the whole pacification process occurring on this favela, which is currently enjoying an extensive pacific coexistence through the appropriate social system and management organizations. With the right and efficient strategies on conflict resolutions, it will be possible to observe that those associationism and coordination of this, support social achievements which may be translated on the whole community dignification, getting out the typical marginal image, to be considered as a renewed social community with all rights and responsibilities.

    The objectives were to study: (1) acceptance of STD screening in non-clinical settings for asymptomatic individuals; (2) risk factors and STD prevalence among individuals in non-clinical and clinical settings; and (3) non-clinical screening of asymptomatic populations as a feasible method for STD control. We recruited 139 males and 486 females between 18 and 30 years of age from a family planning clinic, schools, and community centers in low-income neighborhoods. We asked about STD symptoms and STD/HIV risk behaviors and tested the individuals for gonorrhea, Chlamydia, syphilis, and HIV. Except for HIV, women recruited directly from the community had higher STD rates than those who came in for care at the clinic. Screening in non-clinical settings in Brazil is feasible and has a high yield among young adults in low-income communities. Infected participants would likely never have otherwise sought care or been tested or treated. STD control efforts could be implemented in any site that can reach populations at risk and become a routine procedure in health care settings where people report for problems unrelated to STDs.

    Full Text Available The aim of this study was to determine the palynological origin, phenolic and flavonoid content, and antioxidant properties of twenty-five samples of bee pollen harvested during a nine-month period (February–November from the Canavieiras municipality (northeastern Brazil. Of the 25 samples analyzed, only two (February 01 and 02 were heterofloral. The predominant pollens in the samples analyzed during that month were: Cecropia, Eucalyptus, Elaeis, Mimosa pudica, Eupatorium, and Scoparia. Ethyl acetate fractions were analyzed by HPLC-DAD. The flavonoids isoquercetin, myricetin, tricetin, quercetin, luteolin, selagin, kaempferol, and isorhamnetin were detected. The flavonoid present in all 22 samples was isolated and identified as isorhamnetin 3-O-b-neohesperidoside. The total phenolic contents determined using the Folin-Ciocalteu reagent ranged from 41.5 to 213.2 mg GAE/g. Antioxidant activities based on the 1,1-diphenyl-2-picryl hydrazyl (DPPH, 2,2-azinobis 3-ethylbenzothiozoline-6-sulfonic acid (ABTS, and Fe2+ ion chelating activity assays were observed for all extracts, and correlated with the total phenolic content.

  7. Ecotourism and sea turtle harvesting in a fishing village of Bahia, Brazil

    Full Text Available Many environmentalists believe ecotourism has the potential to generate net benefits for people and nature. For more than two decades, the Brazilian Sea Turtle Conservation Program (TAMAR has provided jobs and income through ecotourism in Praia do Forte, Brazil, in exchange for reduced harvesting of sea turtles. In this article we evaluate the relationships between ecotourism at TAMAR and local support for sea turtle conservation. Nine months of ethnographic research (2006-2008 suggest that ecotourism-related employment and income have been somewhat stable and reliable. The average income of respondents who worked with TAMAR was lower than that reported by people not working with TAMAR. Workers noted other non-economic benefits. Though the majority supported sea turtle conservation, it is unclear how feelings will waver with new mass tourism developments in the region. As the cost of living increases, residents may increasingly be inclined to look for work outside TAMAR. Development also attracts new immigrants, making it difficult for locals to control sea turtle harvesting. These trends challenge the notion that economic incentives for locals alone will ensure conservation. Further research is needed to understand the conditions under which ecotourism may foster long-term conservation in the face of larger developments surrounding community ecotourism projects.

    Fifty cores were recovered from the sea bottom in the central portion of the continental shelf of the State of Bahia, between the Marau Peninsula and the city of Olivenca. Thirty six of these cores were collected by divers at up to 40 m deep waters. Fourteen cores were collected by piston cores in areas ranging from the continental shelf to the upper slope. All cores were described, photographed and sampled for grain size and bio stratigraphic analysis. These data were used to prepare textural and facies maps of the continental shelf. The piston cores were run parallel to sub-bottom profiling surveys. Results show that there is a strong reflector located 3 - 4 m below the sediment- water interface, which limited the penetration of the piston cores. This reflector represents a sequence boundary separating the holocene from the pleistocene sequences. A transgressive system tract has been deposited on the top of this surface along with the early stages of the high stand system tract, particularly on the inner shelf. Because of the starved character of this shelf, notably on its external portion, a detailed application of sequence stratigraphy concepts has not been possible. Only at the inner shelf/shore face there is evident pro gradation of siliciclastics over carbonates. Several submarine valleys dissect the outer shelf/upper slope, thus acting as channels that transport continental shelf sediments to the deeper portions of the basin. (author)

    Full Text Available The Port of Salvador (12°58'S, 38°30'W receives cargo ships from different regions such as southeast Asia, North Atlantic, Mediterranean, Africa, North and South America. Thus, the presence of this port enhances the probability of new species arriving and establishing in Todos os Santos Bay (TSB, in which the port is located. Ascidians are sessile filter-feeding invertebrates with short lived larvae and thus are good indicators of bioinvasion. We surveyed the ascidian fauna on three different occasions: August 1999, June 2004 and December 2007. Nineteen species were identified belonging to the following families: Ascidiidae (Phallusia nigra, Ascidia cf. multitentaculata, A. nordestina, A. papillata, A. scalariforme, A. cf. tapuni, A. tenue, Corellidae (Rhodosoma turcicum, Pyuridae (Microcosmus anchylodeirus, M. exasperatus, M. helleri, Pyura vittata, Herdmania pallida, and Styelidae (Polycarpa cf. reviviscens, P. spongiabilis, P. tumida, Polycarpa sp., Styela canopus, Cnemidocarpa irene. Only A. nordestina, A. papillata, A. scalariforme and P. spongiabilis are possibly native to this region, while P. tumida and C. irene were classified as introduced. Microcosmus anchylodeirus, H. pallida, P. vittata, M. exasperatus, M. helleri, S. canopus, A. cf. multitentaculata, A. tenue and P. nigra were classified as cryptogenic. Most are widely distributed in all oceans and their native geographic distribution is unknown, while A. cf. multitentaculata and A. tenue occur only in the Atlantic, with disjunct distributions. Polycarpa cf. reviviscens, P. tumida and M. anchylodeirus are registered for the first time on the coast of Brazil. Colonial ascidians from this collection are still being studied. The large number of cryptogenic and introduced species indicates the necessity of monitoring TSB for expansion of these populations and the need for the establishment of control programs.

    Full Text Available OBJECTIVE: To study patterns of alcohol consumption and prevalence of high-risk drinking. METHODS: A household survey was carried out in a sample of 2,302 adults in Salvador, Brazil. Cases of High-Risk Drinking (HRD were defined as those subjects who referred daily or weekly binge drinking plus episodes of drunkenness and those who reported any use of alcoholic beverages but with frequent drunkenness (at least once a week. RESULTS: Fifty-six per cent of the sample acknowledged drinking alcoholic beverages. Overall consumption was significantly related with gender (male, marital status (single, migration (non-migrant, better educated (college level, and social class (upper. No significant differences were found regarding ethnicity, except for cachaça (Brazilian sugarcane liquor and other distilled beverages. Overall 12-month prevalence of high-risk drinking was 7%, six times more prevalent among males than females (almost 13% compared to 2.4%. A positive association of HRD prevalence with education and social class was found. No overall relationship was found between ethnicity and HRD. Male gender and higher socioeconomic status were associated with increased odds of HRD. Two-way stratified analyses yielded consistent gender effects throughout all strata of independent variables. CONCLUSIONS: The findings suggest that social and cultural elements determine local patterns of alcohol-drinking behavior. Additional research on long-term and differential effects of gender, ethnicity, and social class on alcohol use and misuse is needed in order to explain their role as sources of social health inequities.

    In this study, concentrations of trace elements in tissues of shrimp species (Litopenaeus vannamei) from farming and zone natural coastal located in the northeastern Brazil were investigated. The elements determination was performed by optical emission spectrometry with inductively coupled plasma (ICP OES). The following ranges of concentrations in the tissues were obtained in µg g-1 dry weight: Al: 13.4-886.5, Cd: 0.93-1.80; Cu: 24.8-152; Fe: 3.2-410.9; Mn: 0.36-24.4; Se: 0.094-9.81 and Zn: 20.3-109.4. The shrimp muscle can be a good iron source (about 88.9 mg-1g dry weight). The distribution of Se concentration in tissues showed much variation between locations, and the concentration levels found in shrimp muscles of wild samples were high, where its levels in 67% of muscle and 50% of others tissues samples exceeded the ANVISA limit, indicating evidence of selenium bioaccumulation. Significant correlation was observed between the following pairs of elements: Fe-Zn (r= -0.70), Mn-Cu (r= -0.74), Se-Cu (r= -0.68), Se-Mn (r= 0.82) in the muscles; Fe-Al (r= 0.99), Mn-Al (r= 0.62), Mn-Fe (r= 0.62), Se-Al (r = 0.88), Se-Fe (r= 0.87), Se-Mn (r= 0.58) in the exoskeleton and Cu-Zn (r = 0.68), Al-Cu (r= 0.88), Fe-Cu (r= 0.95) and Fe-Al (r= 0.97) in the viscera.

    Full Text Available In the few cases of acute childhood diarrhea that require antimicrobial therapy, the correct choice of the drug depends on detailed previous knowledge of local strains. In order to establish such parameters in our city, we reviewed the results of all 260 positive stool cultures of children between 0 and 15 years of age during two years at a pediatric tertiary care facility in Salvador, Brazil. Bacterial strains had been presumptively identified by culturing in selective media and by biochemical testing, and their antimicrobial susceptibility patterns were automatically detected by the MicroScan Walkaway System. Data about patients' sex and age, monthly distribution of the cases, pathogens isolated and their antimicrobial resistance patterns were recorded. Males corresponded to 55.4% of our sample, and most of our patients (42.7% were between one and four years of age. Shigella was the commonest pathogen, being found in 141 (54.3% cultures, while Salmonella was found in 100 (38.4% cultures and Enteropathogenic E. coli in 19 (7.3%. Salmonella was the main causal agent of diarrhea in children younger than five years old, whereas Shigella was the most frequent pathogen isolated from the stools of children between five and 15 years old. The peaks of incidence correspond to the periods of school vacations. Shigella specimens presented a very high resistance rate to trimethoprim-sulfamethoxazole (90.1% and to ampicillin (22.0%, while Salmonella presented very low resistance rates to all drugs tested. These data are useful for practitioners and they reinforce the need for continuous microbiological surveillance.

    For 33 years, a primary lead smelter operated in Santo Amaro (Brazil). Since the 1970s, large amounts of Pb and Cd have been widely documented in the blood and hair of people living near the smelter. The plant closed down in 1993, and several years later, the Pb levels in the blood of children under 4 years of age living near the smelter were high, where the disposed lead slag was suspected to be the main source of this contamination. The objective of this study is to elucidate the source of the Pb contamination and any other potentially toxic contamination, focusing on the characterization of the slag. The samples used for this characterization study were taken from the slag heaps. The results of the chemical analysis showed that the major constituents of the slag, in decreasing order of wt%, were the following: Fe{sub 2}O{sub 3} (28.10), CaO (23.11), SiO{sub 2} (21.39), ZnO (9.47), MgO (5.44), PbO (4.06), Al{sub 2}O{sub 3} (3.56), C (2.26), MnO (1.44), Na{sub 2}O (0.27), S (0.37), K{sub 2}O (0.26), and TiO{sub 2} (0.25). The Cd content of the slag was 57.3 mg/kg, which is relatively low. The X-ray diffraction and the electron probe microanalyzer X-ray mapping indicated that the major phases in the slag were wuestite, olivine, kirschsteinite, and franklinite. Only spheroidal metallic Pb was found in the slag. The leaching study showed that the slag was stable at a pH greater than 2.8, and only in an extremely acidic environment was the solubilization of the Pb enhanced significantly. The solubilization of Zn was very limited in the acidic and alkaline environments. These results can be explained by the limited leachability of the metallic Pb and Zn-bearing compounds. The leaching study used TCLP, SPLP, and SWEP and indicated that the lead slag was stable in weak acidic environments for short contact times.

    Full Text Available The aim of this study was to determine the structure of a rhodolith bed along a depth gradient of 5 to 25 m in the shelf in front of Salvador City, a region of northeastern Brazil. The dimensions, morphology and coralline algae composition of the rhodoliths were analyzed, as well as the vitality, density, and associated flora of the bed at three depths: 5, 15 and 25 m. Samples were obtained by SCUBA divers in summer 2007. Five rhodolith-forming taxa were identified: Sporolithon episporum, Lithothamnion brasiliense, Lithothamnion superpositum, Mesophyllum erubescens, and Lithophyllum sp. The encrusting growth form and the spherical shape were predominant at all depths. Rhodolith dimensions and vitality decreased and the density increased from the shallow to the deepest zones. Fifty-six macroalgal species were found as rhodolith-associated flora. The shallower depth presented higher values for macroalgal biomass and number of species. These results associated with other recent rhodolith bed descriptions indicate that the pattern of Brazilian rhodolith bed structure along depth gradients may be related to a combination of the extent and slope of the continental shelf.O objetivo deste estudo foi determinar a estrutura de um banco de rodolitos ao longo de um gradiente de profundidade na plataforma em frente à cidade de Salvador, nordeste brasileiro.

    Between February and November 2007, the El Paso Oleo e Gas do Brasil Ltda. carried out a second exploratory campaign at the BM-CAL-4 Block (Camamu-Almada Basin), installing a real-time transmission metocean data monitoring system. Two metocean Wavescan (WS) buoys from Fugro were installed, transmitting current, wave and wind data to the El Paso crises room. The WS1 was positioned near the oil (10,5 km from the shore, at 22m depth), and the WS2 was located near the entrance of Barra Grande area (4,w km from the coast, at 10m depth). The real rime data fed the mathematical simulation using an oil spill model from Fugro Oceansatpeg. The metocean data Real-Time Environmental Monitoring System proved to be an important tool in the environmental management of the drilling activity located near the coastline.

    The orchid-bee faunas of 'Parque Nacional do Monte Pascoal', 'Parque Nacional do Descobrimento' and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the 'Parque Nacional do Monte Pascoal', the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at 'Parque Nacional do Monte Pascoal' and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

    This study aimed to analyze the prevalence of negative self-rated health and associated factors in the quilombola community (descendants of escaped slaves) in Vitória da Conquista, Bahia State, Brazil. A household survey was conducted with 797 adults in 2011. Data on self-rated health, socioeconomic and demographic characteristics, lifestyle, social support, health status, and access to health services were obtained through questionnaires. Multivariate logistic regression analysis was performed, adjusted for sex and age. Prevalence of negative self-rated health was 12.5%. After statistical modeling, the following variables remained associated with self-rated health: skin color, schooling, adequate consumption of fruits and vegetables, chronic illness, physical limitations, and at least one medical visit in the previous 12 months. Self-rated health was associated with socioeconomic/demographic dimensions, lifestyle, social support, and health status.

    Full Text Available We analyzed the diet composition, endoparasites and sexual size dimorphism of the microhylid frog Chiasmocleis capixaba (Microhylidae from a "mussununga" habitat in the municipality of Nova Viçosa, southern Bahia state, Brazil. All the 119 specimens analyzed were collected in a single night of heavy rainfall. Females (mean snout-vent length = 15.7 + 3.0 mm were significantly larger than males (mean snout-vent length = 13.2 + 2.1 mm, and specimens of both sexes were smaller than those of a conspecific population previously reported in Aracruz, state of Espírito Santo state. The diet of C. capixaba was dominated by mites, ants and collembolans. Seventy-nine frogs (66.4% of the total were infected by helminths, all belonging to a single species, Cosmocerca ornata, an intestinal nematode parasite.

    2013-09-01

    This study focuses on the meanings assigned to practices for cervical cancer prevention among women from low-income neighborhoods in Salvador, Bahia State, Brazil. This was a qualitative study based on content analysis of semi-structured interviews with 15 women 24 to 68 years of age. The results showed high appreciation of the Pap smear test, performed as part of routine gynecological examination (but without the patient necessarily having biomedical knowledge of its role). Besides accessibility and quality of health services, other factors influence the way the women assign meaning to cervical cancer prevention. Moral values associated with sexuality and gender influence risk perception, adoption of preventive practices, and interpretation of cervical cytology results. The ongoing practice of the Pap smear test is part of the construction of femininity, which is associated with maturity and personal responsibility for self care in a context of medicalization of the female body.

    Full Text Available Abstract Social and sexual contact networks between men who have sex with men (MSM play an important role in understanding the transmission of HIV and other sexually transmitted infections (STIs. In Salvador (Bahia State, Brazil, one of the cities in the survey Behavior, Attitudes, Practices, and Prevalence of HIV and Syphilis among Men Who Have Sex with Men in 10 Brazilian Cities, data were collected in 2008/2009 from a sample of 383 MSM using Respondent Driven Sampling (RDS. Network analysis was used to study friendship networks and sexual partner networks. The study also focused on the association between the number of links (degree and the number of sexual partners, in addition to socio-demographic characteristics. The networks’ structure potentially facilitates HIV transmission. However, the same networks can also be used to spread messages on STI/HIV prevention, since the proximity and similarity of MSM in these networks can encourage behavior change and positive attitudes towards prevention.

    2001-11-01

    Full Text Available This paper deal with on the metasedimentary country-rocks of the chromite-bearing ultramafic rocks that occur in the “Jacurici River Valley Chromium District” northeastern Bahia, Brazil. This region presents a complex geologic-petrologic framework of rocks that were intensely deformed, metamorphosed and transformed by metasomatic processes, making it difficult to interpret their volutionary/metamorphic record. Although the metasedimentary country rocks have also been affected by such processes, it is possible to distinguish evidence of a previous high-grade metamorphism that affected them. Thermobarometric data for the observed mineralogical associations indicate P-T conditions around 750-800ºC and 7-8 kb for the metamorphic peak, based mainly on the presence of olivine in marbles and the cordierite-garnet-sillimanitespinel association in aluminous gneisses.

    Full Text Available We examined aspects of the population ecology of the gastropod Stramonita haemastoma at Ilhéus, Bahia, Brazil. We collected monthly from October 2007 through September 2008 on a sandstone bank 1.5 km long, on which two points and two sampling levels were defined. We took five previously randomised replicates at each level, using a square enclosing an area of 0.0625 m². The snails were photographed, counted, and measured at the site. Both recruits and other individuals in the population preferentially inhabit the regions closer to the lower shore, where they are submerged for longer periods and are less subject to physiological stresses caused by temperature variation and desiccation. The cracks and holes in the bank serve as refuges and places for S. haemastoma to lay their egg capsules. Recruits were observed throughout the study period, and the population showed continuous reproduction.

    Full Text Available A study about the horizontal stratification of the sand fly fauna in two distinct ecosystems, caatinga area, endemic for visceral leishmaniasis, and the tropical rain forest area, endemic for cutaneous leishmaniasis, was performed in the state of Bahia, Brazil. Lutzomyia longipalpis was predominant in the caatinga, and following it came the species L. capixaba and L. oswaldoi. In the tropical rain forest other species were found, such as L. intermedia, L. migonei, L. whitmani, L. yuilli, L.fischeri, L. damascenoi, L. evandroi, L. monticola, and L. lenti. It was found that the geographical limits of the vector species of visceral and cutaneous leishmaniasis are clearly defined by the biological and phytogeographic characteristics.

    Bahia is the most important cacao-producing state in Brazil, which is currently the sixth-largest country worldwide to produce cacao seeds. In the eighteenth century, the Comum, Pará and Maranhão varieties of cacao were introduced into southern Bahia, and their descendants, which are called ‘Bahian cacao’ or local Bahian varieties, have been cultivated for over 200 years. Comum plants have been used to start plantations in African countries and extended as far as countries in South Asia and Oceania. In Brazil, two sets of clones selected from Bahian varieties and their mutants, the Agronomic Institute of East (SIAL) and Bahian Cacao Institute (SIC) series, represent the diversity of Bahian cacao in germplasm banks. Because the genetic diversity of Bahian varieties, which is essential for breeding programs, remains unknown, the objective of this work was to assess the genetic structure and diversity of local Bahian varieties collected from farms and germplasm banks. To this end, 30 simple sequence repeat (SSR) markers were used to genotype 279 cacao plants from germplasm and local farms. The results facilitated the identification of 219 cacao plants of Bahian origin, and 51 of these were SIAL or SIC clones. Bahian cacao showed low genetic diversity. It could be verified that SIC and SIAL clones do not represent the true diversity of Bahian cacao, with the greatest amount of diversity found in cacao trees on the farms. Thus, a core collection to aid in prioritizing the plants to be sampled for Bahian cacao diversity is suggested. These results provide information that can be used to conserve Bahian cacao plants and applied in breeding programs to obtain more productive Bahian cacao with superior quality and tolerance to major diseases in tropical cacao plantations worldwide.

Mesmo assim, ainda é possível encontrar uma série de microrganismos presentes neste produto e que servem como indicadores de qualidade. O objetivo deste trabalho foi avaliar a qualidade microbiológica do mel produzido por espécies de abelhas sem ferrão (Trigonini do Estado da Bahia. Quatorze amostras de mel foram avaliadas quanto ao teor de umidade, atividade de água, contagem padrão de bolores e leveduras, e presença de microrganismos do grupo coliforme. Um total de 50,0% das amostras apresentou contagem padrão para bolores e leveduras acima do máximo permitido pela regulamentação brasileira para alimentos. Esta desclassificação de amostras assepticamente colhidas indica a necessidade de identificação desta microbiota e sua possível ocorrência natural no mel produzido por este grupo de abelhas. Nenhuma das amostras foi desclassificada em relação à contagem de microrganismos do grupo coliforme.Honey is a product that presents antimicrobial activity attributed to physical and chemical factors. Even so, it is still possible to find many microorganisms present in this product, which can be used as quality indicators. The objective of this work was to evaluate the microbiologic quality of the honey produced by stingless bee species from the State of Bahia, Brazil.

    In the continental portion of the Almada Basin outcrops of canyon filling deposits are represented by turbidite channels and associated facies from Urucutuca Formation. The canyon - semi-exhumated - eroded basement and pre-Cenomanian sedimentary rocks. The field study of the outcrops and cores obtained in adjacent perforations lead to the understanding of the facies and processes that controlled the deposition of these channeled turbidite that can be compared to the reservoirs of many oil fields in Brazil. The Almada canyon is a submarine conduct of tectonic origin that was enlarged by the repeated passing of turbidity currents. During the rift phase and the Albian period, compressive events reactivated old N E and N W faults in the basement as trans current fault systems. The continuation of these stresses, from the Cenomanian to the Maastrichtian, developed normal faults that controlled a submarine canyon that connected the continent, where an estuary was formed between the mountains, to the deep marine region of the basin. The canyon has received sediments brought by catastrophic fluvial floods coming from the surrounding mountains, which formed hyperpicnal flows that have evolved as turbidity currents, thus causing erosion of the substrate and carrying a huge volume of sediments to the basin. A part of that load was deposited in the canyon and formed turbidite channels filled by conglomerates, sandstones and shales. These moderately to highly efficient turbidite are intercalated to pro delta pelites and low density turbid plumes deposits, which have mostly been re mobilized as slump and debris flows (chaotic deposits). Pelites were accumulated mainly in the normal fluvial sedimentation phases, when the sandy sediment was retained next to the canyon head and were reworked by the tides on the upper part of the estuary.

    Teofilândia granitoids are representative of the Paleoproterozoic plutonic rocks, which intruded the Serrinha block, an Archean crustal fragment of the Sao Francisco Craton (Bahia, Brazil). Three plutons were emplaced, the Teofilândia granodiorite, the Barrocas trondhjemite and the Santa Rosa granite, respectively dated at 2130, 2127 and 2073 Ma. The two first plutons are calc-alkaline rocks following a trondhjemitic trend. They resemble Archean TTGs (tonalites-trondhjemites-granodiorites) by their major and trace element compositions and especially by their fractionated REE patterns, with very low HREE contents. These juvenile magmas resulted from partial melting of a young mafic protolith, likely represented by the nearby Rio Itapicuru greenstone belt. Barrocas trondhjemite and Teofilândia granodiorite derive from similar sources, possibly at different depths and with a different degree of melting. The rocks were deformed at high temperature during the Trans-Amazonian collision and are therefore pre-collisional and ascribed to a subduction stage. The younger Santa Rosa pluton is a small, syn-to post-collisional granite that derived from anatexis of the Archean crust. It is representative of a second, volumetrically minor, plutonic episode of potassic, shoshonitic or alkaline affinities. The large amount of 2.1 Ga granitoids emplaced in Brazil as well as in the West African craton, suggests that, at that time, a global event of possible mantle origin was responsible for the intense magmatic activity that involved both crustal accretion and crustal reworking in many places of the world.

    Full Text Available Mirroring the global increase of registered cases of American visceral leishmaniasis (AVL, this infection has become a growing public health problem in Brazil during the last several years. As the traditional approach to control employed by the governmental health agencies has failed to reduce the incidence and epidemic outbreaks of this illness, we propose a re-evaluation of the national strategy of intervention and monitoring. Our thinking is based on a series of spatio-temporal scan statistics of the west-central region of the state of Bahia covering the 11-year period from 1994 to 2004. By analyzing the situation, spatially and temporally, we show that the disease is a not only a growing focal threat but that it is also appearing in the form of endemic clusters in the cities. The areas where the disease has been found have been classified according to the degree of risk of infection for humans and canines. The overall objective of this study was to identify areas of increased risk of AVL, including its seasonality, and to suggest ways and means to improve the detection of the disease. The findings presented here should not only be of interest for the efforts to control AVL in the study area but also be useful for developing control strategies in other endemic regions of Brazil.

Only 231 TSIs were completed, since 106 students were illiterate. School grades were obtained for all participants. A questionnaire evaluating school resources, and teacher profiles was answered by 200 teachers. Raven and TSI test scores were highly correlated (r = 0.53, p < 0.001, but both correlated weakly with overall school grade (r = 0.22, p < 0.001 and r = 0.12, p < 0.07 respectively. For individual school grades, the Raven scores showed statistically significant correlation with all subjects, while the Brazilian TSI presented statistically significant correlation only with geography, history and sciences. Boys' mean scores were higher than girls' for both the Raven and the TSI Tests, but for the school grades girls performed better. In general, level of cognitive development was below that expected for children in the age-group analyzed.

    Full Text Available In this study were examined the species richness and seasonal abundance of cavity-nesting bees in areas of dry semi-deciduous forest and caatinga in the State of Bahia, Brazil. Sampling was done employing two types of trap-nests: bamboo canes and tubes made of black cardboard with dimensions of either 58 x 6 mm or 105 x 8 mm. The traps were inspected once a month. One hundred and forty-six nests of 11 bee species were collected in the forest, and 121 nests of seven species were collected in the caatinga. Five species of cleptoparasitic bees were also reared from these nests. The highest nesting frequencies occurred in the wet season in both areas. Nests parasitism was important only for Centris tarsata Smith, 1874, and was higher at the caatinga site than in the forest. The mortality of pre-emergent adults was high, especially in C. tarsata,Tetrapedia diversipes Klug, 1810 and Euglossa cordata (Linnaeus, 1758. Information on the number of cells per nest, the size, shape, and arrangement of brood cells in the nests, as well as the number of adults produced and the number of generations per year are also presented. Species richness, temporal patterns of nesting, and percentage of parasitism were compared with other habitats.Neste estudo foram investigadas a riqueza de espécies e a abundância sazonal de abelhas que nidificam em cavidades em áreas de Floresta estacional semi-decídua e Caatinga na Bahia.

    During March 1994 cases of a exanthematic acute disease were reported in the municipalities of Itagemirim, Eunápolis and Belmonte, state of Bahia. Dengue fever was confirmed by serology (MAC-ELISA) and by dengue virus type 2 isolation, genotype Jamaica. Signs and symptoms of classic dengue fever were observed with a high percentual of rash (73.8%) and pruritus (50.5%). Major haemorrhagic manifestations were unfrequent and only bleeding gum was reported. Dengue virus activity spreaded rapidly to important tourism counties like Porto Seguro, Ilhéus, Santa Cruz de Cabrália, Prado, Alcobaça and others, representing a risk for the spreading of dengue virus into the country and abroad.

    To investigate spatial clusters and possible associations between relative risks of leprosy with socio-economic and environmental factors, taking into account diagnosed cases in children under 15 years old. An ecological study was conceived using data aggregated by municipality to identify possible spatial clusters of leprosy from 2005 to 2011. Relative risks were calculated accounting for the respective covariate gender. The second stage of the analysis consisted of verifying possible associations between the relative risks of leprosy as a dependent variable, and socio-economic and environmental variables as independent. This was performed using a multivariate regression analysis according to a previously defined conceptual framework. Overall rates have decreased from 0.88/10 000 in 2005 to 0.52 in 2011. Spatial scan statistics identified 4 high-risk and 6 low-risk clusters. In the regression model, after allowing for spatial dependence, relative risks were associated with higher percentage of water bodies, higher Gini index, higher percentage of urban population, larger average number of dwellers by permanent residence and smaller percentage of residents born in Bahia. Although relative risks of leprosy in Bahia have been decreasing, they remain very high. The association between relative risks of leprosy and water bodies in the proposed geographic scale indicates that hypothesis linking M. leprae and humid environments cannot be discarded. Socio-economic conditions such as inequality, a greater number of dwellers by residence and migration are derived from the urbanisation process carried out in this State. Precarious settlements and poor living conditions in the cities would favour the continuity of leprosy transmission. © 2014 John Wiley & Sons Ltd.

    In recent years, growing interest has focused on determining the performance of materials and evaluating the service life of structures exposed to various environmental forces. In this context, the determination of the aggressive potential of marine salts on mortars used as external renders is critical. The present study aimed to evaluate the spatial distribution of marine salts relative to distance from the sea. This was done by monitoring the deposition rate of chlorides and sulfates in wet candle sensors, located at nine stations scattered around the Metropolitan Region of Salvador, state of Bahia, Brazil. The study also determined the effectiveness of water-soluble salts at penetrating three different types of mortars of varying cement content via deposition and diffusion. The methodology employed enabled an evaluation of the efficiency of the monitoring sensors' measurement of the aggressiveness potential of local marine aerosol, and determination of the comparative performance of the three mortars tested, from the standpoint of resistance to salt penetration. The type and amount of salts captured both in solution and in powder samples extracted from the mortars were determined by ion chromatography. The analysis of the various types of mortars tested indicated which types are more resistant to the aggressive potential of the region's marine aerosol and the distance from the shore where local buildings are liable to be most strongly affected.

    This paper examines the impact of violent crime on working conditions, health, and security for bus drivers and ticket takers in the mass transportation system in Salvador, Bahia, Brazil. The research included 195 interviews with workers, labor union officials, passengers, management, and police. In the last ten years there have been 20,572 robberies in a fleet of 2,400 buses operated by 10,151 workers, with 67 deaths and more than US$500,000 in company losses. Perpetrators are typically poor, unemployed youths, the majority of whom first offenders, seeking easy money primarily for leisure pursuits. The average "take" from such robberies is minimal. The authors observed a pattern of bus robberies as a psychological power game which, for bus workers, apart from physical injuries and fatalities, generates fear, identity conflicts, tense relations with passengers, and labor conflicts involving the recovery of stolen fares and worker and passenger security issues. The article also outlines and evaluates the efficiency of security measures including the use of lethal force by police.

    The characterization and identification to species and subspecies of 20 stocks of Leishmania isolated from the region of Três Braços, Bahia, Brazil, are described: 17 stocks were from patients and three from dogs. The following techniques were used (i) biological (growth in culture, hamster tissues and phlebotomine gut), (ii) biochemical (isoenzyme and kinetoplast DNA analysis) and (iii) immunological (using monoclonal antibodies). All except two stocks belong to the L. braziliensis complex. One of these two corresponded to L. mexicana amazonensis but the other, while clearly in the mexicana complex, showed slight differences from the L. mexicana amazonensis reference strain on isoenzyme analysis. Two stocks from different lesions in the same patient and with different growth characteristics in hamster tissues were both identified as L. braziliensis braziliensis. All the fully characterized stocks of the L. braziliensis complex were identified as L. braziliensis braziliensis. L. braziliensis guyanensis was not identified. Dog and human stocks of L. braziliensis braziliensis were indistinguishable. From these findings and other evidence, L. braziliensis braziliensis seems to be the predominant species transmitted in Três Braços.

    We carried out a study to characterize fruit fly populations on an organic guava orchard (Psidium guajava cv. Paluma) in the municipality of Una, southern region of the state of Bahia, Brazil, using faunistic analysis of the adult fruit f y specimens captured in McPhail traps from January 2004 through March 2007. A total of 22,673 specimens of Anastrepha (15,306 females and 7,367 males) were captured. Thirteen species of Anastrepha were recorded. A. fraterculus and A. obliqua were the more frequent and dominant species, accounting for 90.1% of all females captured in the traps. A. fraterculus was the predominant species (more frequent, constant and dominant). The high value of the Simpson index (0.62) and the low values of Shannon-Wiener (0.83) and equitability (0.49) indices indicated the dominance and high frequency of A. fraterculus and A. obliqua on the guava orchard despite the presence of other fruit species as potential hosts of fruit flies.

    Full Text Available AbstractLutjanus analis (Mutton snapper, Lutjanus jocu(Dog snapper and Mycteroperca bonaci (Black grouper are reef fishes of high commercial value, and are among the principal exploited reef resources on the eastern and northeastern coast of Brazil. These species share the habit of forming transient spawning aggregations, predictable in time and space, which leaves them particularly vulnerable. The present study aimed to obtain indirect indicators of periods and places of spawning aggregations for these species, based on the exploratory analysis of available data on commercial catches and fishing efforts in Southern Bahia. Line fishery landings data were monitored in 12 locations in the region, and catch records of Mutton snapper (1320 landings, Dog snapper (654 and Black grouper (1162 were analyzed. A strategy was developed for exploratory analysis of monthly CPUE variation and individual distribution of CPUE per trip. The results showed the occurrence of aggregations in 26 specific sites, with values of relative abundance far above the annual mean, during spring/summer and autumn/winter. The occurrence of these anomalous catches was validated with the fishermen responsible for respective fishing trips. Additional studies are needed to confirm spawning activity at these sites. Analysis of inter-annual variation suggests a decreasing trend in relative abundance of Black grouper and Mutton snapper, possibly associated with unregulated fishing of spawning aggregations.

    This study aimed to assess pre-hypertension and hypertension-related factors in 1,125 seven- to-14-year-old subjects enrolled in the public school system in Salvador, Bahia State, Brazil. Exposure variables, namely body mass index, waist circumference, gender, age, physical activity, environmental and housing status, family income, diet, schooling, and maternal age were analyzed by polytomous logistic regression, and the outcome variable was categorized as normal, pre-hypertensive, and hypertensive. Prevalence of high blood pressure was 14.1%, including the prevalence of both hypertension (4.8%) and pre-hypertension (9.3%). An association was shown between pre-hypertension and overweight (OR: 3.13; 95%CI: 1.75-5.57). Hypertension was associated with overweight (OR: 3.02; 95%CI: 1.45-6.28), female gender (OR: 2.49; 95%CI: 1.24-4.98), and high-risk eating patterns (OR: 1.93; 95%CI: 1.04-3.56). In short, prevalence of pre-hypertension and hypertension in children and adolescents was higher among girls and individuals with overweight and inadequate diet.

    The launch of the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor aboard the Terra and Aqua platforms in 1999 and 2002, respectively, with temporal resolutions of 1 to 2 days opened the possibility of using a longtime series of satellite images to map land use and land cover classes from different regions of the Earth, to study vegetation phenology, and to monitor regional and global climate change, among other applications. The main objectives of this study were twofold: to analyze the radiometric quality of the time series of enhanced vegetation index (EVI) products derived from the Terra MODIS sensor in western Bahia State, Brazil, and to identify the most appropriate filter to smooth MODIS EVI time series of the study area among those available in the public domain, the TIMESAT algorithm. The 2000 to 2011 time period was considered (a total of 276 scenes). The radiometric quality was analyzed based on the pixel reliability data set available in the MOD13Q1 product. The performances of the three smoothing filters available within TIMESAT (double logistic, Savitzky-Golay, and asymmetric Gaussian) were analyzed using the Graybill's F test and Willmott statistics. Five percent of the MODIS pixels from the study area were cloud-affected, almost all of which were from the rainy season. The double logistic filter presented the best performance.

The new species is promptly distinguished from other characids by having four, rarely three, robust, rounded, and usualy tricuspid teeth on inner premaxillary series and similar teeth on dentary. The species is furthermore characterized by a series of unusual character states in the Characidae, including head blunt in lateral and dorsal views, longitudinal foreshortening of lower jaw, ventral margin of third infraorbital distinctly separated from horizontal limb of preopercle, leaving a broad area without superficial bones, mesethmoid anteroventrally expanded, and adductor mandibulae and primordial ligament remarkably developed. Analysis of gut contents of adults revealed the almost exclusive presence of crushed shells of tiny gastropods of the family Hydrobiidae. The robust anatomy of jaws, teeth, muscles and associated ligaments are likely adaptations to durophagy, a feeding strategy unusual among characids. Astyanax brucutu is known only from its type locality, an approximately 670 m long, transparent and isolated perennial epigean watercourse surrounded by subterranean or intermittent rivers. The distinctive combination of environmental features characterizing the area of occurrence of the new species is not observed elsewhere in the basin or adjacent basins. A series of severe anthropogenic impacts, associated with the restricted geographic range of the species, implies that A. brucutu should be regarded as Critically Endangered (CR) according to IUCN Red List Criteria.

    Full Text Available Twenty-two propolis samples produced by Apis mellifera L. in an area of the Semiarid region the the State of Bahia (Agreste of Alagoinhas, Brazil, were palynologically analyzed and quantified regarding their levels of total phenolic compounds. These samples were processed using the acetolysis technique with the changes suggested for use with propolis. We found 59 pollen types belonging to 19 families and 36 genera. The family Fabaceae was the most representative in this study with nine pollen types, followed by the family Asteraceae with seven types. The types Mikania and Mimosa pudica occurred in all samples analyzed. The types Mimosa pudica and Eucalyptus had frequency of occurrence above 50% in at least one sample. The highest similarity index (c. 72% occurred between the samples ER1 and ER2, belonging to the municipality of Entre Rios. Samples from the municipality of Inhambupe displayed the highest (36.78±1.52 mg/g EqAG and lowest (7.68 ± 2.58 mg/g EqAG levels of total phenolic compounds. Through the Spearman Correlation Coefficient we noticed that there was a negative linear correlation between the types Mimosa pudica (rs = -0.0419 and Eucalyptus (rs = -0.7090 with the profile of the levels of total phenolic compounds of the samples.

    The knowledge on diet composition of the freshwater mussel Diplodon enno (Ortmann) would aid in its culture and propagation allowing, this way, the replacement of natural endangered populations in Brazil. Microalgae are the main food source for captive mussels and unionids have displayed an ability to sort algae based on the cellular characteristics prior to ingestion. The main objective of the present work is to analyze the phytoplankton composition of the water from and of the gastrointestinal contents of the mussel D. enno, as an initial step for development of a suitable rearing diet. Therefore, water samples and bivalve specimens were collected from S. Francisco River, city of Paulo Afonso, Bahia, Brazil. The microalgal composition found in water and stomach/gut content samples was very diverse being represented by the following divisions: Cyanophyta, Chlorophyta, Dinophyta and Heterokontophyta (Diatoms). Concerning the relative abundance of microalgae divisions, it is possible to state, for the water and gastrointestinal contents, that Cyanophyta represents 15% and 14%, Chlorophyta 54% in both, Heterokontophyta 31% and 27% and Dinophyta 0% and 5%, respectively. According to the Brazilian CETESB criteria for phytoplankton species classification, 50% of Cyanophyta and 15% of Chlorophyta species observed in the water samples were classified as "very frequent", as were 68% of Heterokontophyta and 33% of Chlorophyta species in the gut/stomach tract samples. Focusing at a species level, although in the water only Coelastrum sp. and Chroococcus sp. were observed in 100% and 75% of the samples, respectively, in the gastrointestinal tract the species Staurastrum sp., Aulacoseira sp., Scenedesmus sp. and Fragilaria crotonensis occurred in 80% to 100% of the samples. The present results showed that D. enno feeds not only on small chlorophytes microalgae, due to their convenient size that facilitates higher feeding rates, but also on large size diatoms, due to a possible

    In pelitic rocks, the effect of melt transfer (loss and/or gain) on phase relations can be successfully predicted via phase equilibrium modeling and more particularly using pseudosections with bulk composition as a variable (e.g. White et al., 2001). One of the most obvious effect of melt loss is the dehydration of the rock that limits further melting and favors the preservation of peak metamorphic assemblage. However, in most cases, melt loss has a limited effect that can be hardly seen mineralogically. Indeed, composition of phases like garnet, cordierite or plagioclase, that are first-order metamorphic phase, will not be affected significantly by melt loss. Therefore, evidences of melt extraction must be evidenced texturally. The goal of this contribution is to present an example where both mineralogical and textural evidences of melt extraction have been inferred. The studied sample is a pelitic granulite from the Paleoproterozoic Itabuna-Salvador-Curaça belt (Salvador da Bahia, Brazil). It is located in the city of Salvador da Bahia, next to the Farol da Bara. Structurally, it is located in a steeply deeping high strain zone that could have play a major role on the segregation and transfer of melt. The gneissic foliation is marked by a compositional banding with centimer-wide quartzo-feldspathic leucosomes in a garnet-bearing granulite. Leucosomes are almost systematically surrounded by a darker layer that is quartz-undersaturated and enriched in spinel and primatic sillimanite. This silica undersaturation is interpreted as the effect of extreme melt extraction and was modeled using phase diagram section. An interesting feature of the rock is that garnet grain size decreases and the number of garnet grains increases in the melanosome away from the leucosome. Furthermore, the type, amount and shape of inclusions in garnet, chemical composition and zoning in garnet also varies greatly and continuously across the gneissic foliation. Texturally, the presence of

    Full Text Available Temporary lakes are common in the semi-arid region of the State of Bahia and form water mirrors in the rainy season. In this period, various vegetal species appear having different life forms adapted to the seasonality conditions of the rainfall regime. This work surveyed the adaptive anatomical structures of some emergent and amphibious monocot species occurring in these lakes. We studied the anatomy of roots, rhizomes, leaves and scapes of Cyperus odoratus, Oxycaryum cubense, Pycreus macrostachyos (Cyperaceae - amphibious species; and of Echinodorus grandiflorus (Alismataceae, Eichhornia paniculata (Pontederiaceae and Habenaria repens (Orchidaceae - emergent species. The anatomical features of the dermal, fundamental and vascular systems confirming the tendency of the adaptive convergence of these plants to temporary lacustrine the environment include: single layered epidermal cells with a thin cuticle layer in the aerial organs; the presence of air canals in all the organs; few or no supporting tissues; and less numerous conducting elements and thinner cell walls in the xylem. The reduction of the supporting tissues, the number of stomata, which can even be absent, and the number of conducting elements and the degree of cell wall lignification in the xylem of the emergent species is more accentuated than that of the amphibious species. The pattern of distribution of aerenchyma in the roots of the studied species was considered important to distinguish between amphibious and emergent life forms.

    The scope of this study was to estimate the prevalence and associated factors of missed opportunities for timely diagnosis of diabetes mellitus in Afrodescendant communities in Vitoria da Conquista in the state of Bahia. It involved a population-based cross-sectional study based on a probability sample (n=797), where 548 individuals were eligible for analysis considering the risk criteria: age of 45 years old and above, increased Body Mass Index and hypertension. The prevalence of diabetes mellitus was estimated at 42.6%. Logistic regression indicated the following statistically associated factors: self-assessed good/very good health conditions; not measuring blood pressure and not consulting with a physician in the past twelve months; and poor access to health services. The high prevalence was associated with factors related to low utilization and poor access to health services. Actions for the diagnosis and prevention of diabetes should prioritize populations at risk, including better education and training of family health care teams, and improvement of attendance at health care units. Enhanced integration between primary and secondary health care actions can positively impact early diagnosis, treatment and reduction of potential complications associated with diabetes in this population.

    The study sought to analyze the nutritional deficit of children and associated environmental factors and maternal and infant characteristics in a major city in the interior of the state of Bahia. Information from mother/child-under-four duos of a birth cohort was assessed. Malnutrition was defined by the height-for-age (H/A) anthropometric index, at a cutoff of -1 z-score relative to the benchmark of the 2006 Multicentre Growth Reference Study. The variables studied were: the characteristics of children (birth weight and multiple births) and mothers (age at the time of birth, education level, parity and performing prenatal exams) and environmental factors (floor and roof material of residence, source of water consumed, indoor plumbing, water used for consumption and ownership of a refrigerator). Logistic regression was used to identify factors associated with nutritional deficit. Nutritional deficit occurred in 24.6% of children. Underweight at birth, inadequate prenatal care, precarious nature of the floor of the home and no indoor plumbing were predictors of malnutrition among children in the study. Factors associated with malnutrition confirm the contribution of social issues in the genesis of malnutrition.

    Full Text Available Abstract Background Blue Land Crab (Cardisoma guanhumi is one of the most important crustacean species captured and commercialized in Brazil. Although this species is not considered to be threatened with extinction, populations of C. guanhumi are known to be rapidly diminishing due to heavy harvesting pressures and degradation of their natural habitats, highlighting the necessity of developing and implanting management and protection strategies for their populations. There have been no ethnozoological publications that have focused specifically on C. guanhumi, in spite of importance of this type of information for developing efficient management plans of resource utilization. So, the present work describes the ethnoecological aspects of the capture and commercialization of C. guanhumi by a fishing community in northeastern Brazil. Methods Field work was carried out in the municipality of Mucuri, Bahia in Brazil, between the months of January and March/2011 through the use of open semi-structured interviews with all of the crustacean harvesters in city who acknowledged their work in capturing this species, totaling 12 interviewees. The informants were identified through the use of the "snowball" sampling technique. In addition to the interviews themselves, the "guided tour" technique and direct observations was employed. Results According all the interviewees, the C. guanhumi is popularly called "guaiamum" and is collected in "apicum" zones. They recognize sexual dimorphism in the species based on three morphological characteristics and the harvesters also pointed two stages in the reproductive cycle during the year and another phase mentioned by the interviewees was ecdysis. All of the interviewed affirmed that the size and the quantities C. guanhumi stocks in Mucuri have been diminishing. All of the interviewees agreed that the species and other mangrove resources constituted their principal source of income. The harvesters dedicated three to

    Full Text Available Since 2002, the Brazilian Ministry of Health has recommended a score system for tuberculosis diagnosis of children and adolescents that does not need bacteriological positivity, because most cases in this age group have few bacteria. An observational, transversal study was carried out at the outpatient health care service of the reference medical service in Salvador, Bahia, including 164 patients with pulmonary tuberculosis, with ages ranging between 1 and 15 years of age, who were treated from 1990 to 2001. The gold standard used to establish the diagnosis was clinical, radiological, epidemiological and based on follow-up data. The score system for diagnosis purposes was tested retrospectively. The median age and the average age of the 164 patients were 6 and 6.62 years (SD ± 4.33, respectively. About 65% of the sample reported a history of close contact with a tuberculous adult. The BCG vaccine coverage was 70.7% (116/164. It was found that 26% (43/164 of the patients had severe malnutrition. Out of this group, 26/43 (60.47% were < 5mm reactive to the tuberculin test. On the other hand, out of the 91 patients with tuberculin test < 5mm, 29% (26/ 91 had severe malnutrition. The use of the score gave the following distribution: a TB very likely in 81.7% (134/164 of the patients; b possible TB in 15.9% (26/164 and TB unlikely in 2.4% (4/164. Among patients who had been vaccinated more than 2 years before, there was a 9 times higher risk of finding a tuberculin test above 10 mm in individuals with probable TB in comparison with the patients with possible or unlikely TB.

    In the cacao-growing region in the southern part of the state of Bahia, the organochlorine insecticides, mainly gamma-benzene hexachloride (BHC) and dichlorodiphenyltrichloroethane (DDT), have been used for about 40 years on cacao crops and in public health programs for control of the insect vectors of different diseases, especially malaria. This paper presents the results of tests performed on 127 persons, all males, between the ages of 15 and 52 years, divided into eight groups as follows: three groups consisted of persons occupationally exposed to 1.5% BHC, that is, technical hexachlorocyclohexane (HCH); two groups consisted of individuals who had had occasional contact with the products or worked in areas near those in which they were used; two groups were appliers of DDT, and the last group--the control group--consisted of 50 individuals who had had no history of occupational exposure to insecticides. All the participants underwent testing to determine the parameters of biochemistry, hematology, and organochlorine insecticide residues in the blood. It was found that improper handling of the products and failure to use individual protective equipment, together with longer time of exposure, significantly increased the rates of GOT and GPT in the appliers of DDT and technical HCH, and in the latter the rates of alkaline phosphatase, albumin, and cholesterol were also found to be higher. In view of the high morbidity among pesticide appliers in agriculture and public health campaigns, it is important to institute programs to teach these workers to avoid contamination of their persons and of the environment by developing good hygiene habits, using individual protective equipment, and correctly handling the products. Rural workers and public health authorities must become aware of the importance of protective equipment, periodic health examinations, and reduced environmental pollution in order to lessen occupational risks of field workers and promote improved

    This work proposes a procedure for the determination of total selenium content in shellfish after digestion of samples in block using cold finger system and detection using atomic fluorescent spectrometry coupled hydride generation (HG AFS). The optimal conditions for HG such as effect and volume of prereduction KBr 10 % (m/v) (1.0 and 2.0 ml) and concentration of hydrochloric acid (3.0 and 6.0 mol L(-1)) were evaluated. The best results were obtained using 3 mL of HCl (6 mol L(-1)) and 1 mL of KBr 10 % (m/v), followed by 30 min of prereduction for the volume of 1 mL of the digested sample. The precision and accuracy were assessed by the analysis of the Certified Reference Material NIST 1566b. Under the optimized conditions, the detection and quantification limits were 6.06 and 21.21 μg kg(-1), respectively. The developed method was applied to samples of shellfish (oysters, clams, and mussels) collected at Todos os Santos Bay, Bahia, Brazil. Selenium concentrations ranged from 0.23 ± 0.02 to 3.70 ± 0.27 mg kg(-1) for Mytella guyanensis and Anomalocardia brasiliana, respectively. The developed method proved to be accurate, precise, cheap, fast, and could be used for monitoring Se in shellfish samples.

    Full Text Available Bacterial meningitis is still a major public health threat inside developing countries. In Brazil, the Department of Public Health estimates that the prevalence of bacterial meningitis is 22 cases per 100,000 persons. During the neonatal period, the bacterial meningitis develops special characteristics that can result in hearing problems and movement loss due to neurological and psychological damages. This study had the aim to analyze the prevalence of bacterial meningitis and sepsis in newborns during the pregnancy period for those using the public health care system in Salvador-Bahia. One of the goal was to describe the risk factors of bacterial meningitis and sepsis in newborns. A second goal was to identify, based on newborn health records, the difficulties to predict issues with the hearing, neurological and psychological problems. This study has a cross-sectional design. The newborns that were included in this study had bacterial meningitis or sepsis within 0-28 days of life. They were admitted in the maternity wards between June-December 2005 at the newborn intensive unit care. We analyzed 72 reports of newborns and only 11 (17% were bacterial meningitis or sepsis newborn cases. These cases were associated to high intake of ototoxic drugs that can cause oto and nephrotoxicity, and cause serious sequels on the child development. Nervous system infection is one of the 2 major problems in clinical practice, especially during the first month after birth. During this first month, the nervous system infection develops special characteristics, which are different from regular symptoms and it requires treatment due to the increased risk to develop complications. It is strongly recommended to monitor ototoxic drugs use to prevent effects on the hearing system.

    The Lagoa Real Uranium Province, situated in South Central Bahia in the region of Caetite and Lagoa Real, is considered the most important monomineralic province of Brazil. The urban population who lives in the proximities of this uranium province in the cities of Caetite, Lagoa Real and Livramento uses public supply water, while the inhabitants of the rural area due to long terms of dry weather use water from wells, cisterns, small dams, reservoirs and dikes which are supplied with the rains. In this work it was determined the concentration of uranium in the water consumed by the rural and urban population living in the proximities of the Lagoa Real Uranium Province. The study comprehends 32 sampling spots spread throughout the region of interest. Samples were collected in January and July 2010, covering superficial, underground and public supply water from the region. The uranium concentrations were determined by an inductively coupled plasma mass spectrometer (ICP-MS). Preliminary results showed that the uranium concentrations in the water from the Lagoa Real Uranium Province varied from 0.064 {+-} 0.005 {mu}g.L{sup -1} to 90 {+-} 1,5 {+-}g.L{sup -1}. It was observed that only two of them obtained values higher than the World Health Organization's recommended limit (2011) of 30 {mu}g.L{sup -1} for maximum uranium concentration in the water for human consumption. For a conclusive evaluation, the uranium concentrations results will be analyzed together with total alpha and beta concentrations determined elsewhere for the same samples. (author)

  20. The blind catfish from the caves of Chapada Diamantina, Bahia, Brazil (Siluriformes: Heptapteridae: description, anatomy, phylogenetic relationships, natural history, and biogeography

    Directory of Open Access Journals (Sweden)

    Flávio A. Bockmann

    Full Text Available Rhamdiopsis krugi, a new troglobitic heptapterid catfish, is described from the caves of Chapada Diamantina, State of Bahia, northeastern Brazil. This species, although frequently cited in the scientific literature along the last seventeen years, remained undescribed largely due to its uncertain phylogenetic affinities. The generic assignment of R. krugi was clouded largely by its high number of unusual morphological features (some related to cave life, for instance: absence of eyes and body pigmentation; presence of a widely exposed pseudotympanum; posterior border of the anterior branch and anterior margin of the arborescent portion of the posterior branch of the transverse process of fourth vertebra joined; dorsal hypural plate commonly with seven rays; ventral caudal plate usually with six rays; dorsal and ventral caudal-fin lobes typically with six branched fin rays each; 38-39 vertebrae; anal fin with 14-17 rays; and lateral line very short. Rhamdiopsis krugi can be easily distinguished from its congeners, R. microcephala and R. moreirai, by its troglomorphic features and by the presence of a shorter lateral line, fewer vertebrae and anal-fin rays, pattern of branching of caudal-fin rays, and several attributes of skeletal system. The affinities of this new species are discussed in light of current phylogenetic knowledge of the family Heptapteridae. Incongruent derived characters do not allow selection of a particular hypothesis of sister group relationships among species of Rhamdiopsis. The occurrence of R. krugi in the rio Paraguaçu basin is possibly due to an event of hydrological capture from a section of the middle portion of the rio São Francisco basin, caused by tectonic events. The semi-arid region where R. krugi presently lives was probably covered by a wide forested area during a humid cycle in Quaternary. A summary of natural history and ecology data of R. krugi, as well as notes on its conservation, are provided. We also

    Full Text Available Background: Periodontitis is an inflammatory disease characterized by the loss of connective tissue and alveolar bone. Different factors are associated with the onset and prognosis of this disease, both environmental and genetic. The latter particularly relate to molecules secreted as a function of the host immune response, such as pro-inflammatory cytokines. Studies indicate that the polymorphism c. 3954C > T in the interleukin-1 β encoding gene (IL1B can be considered as an aggravating factor in the periodontitis condition. Aims: This study aimed to evaluate whether there is an association between the IL1B c. 3954C > T gene polymorphism and the prevalence of periodontitis in the population from Vitσria da Conquista-Bahia, Brazil. Materials and Methods: A total of 347 subjects (134 cases and 213 controls who provided epithelial tissue of the oral cavity and saliva samples for DNA extraction and quantification of IL1B, respectively, were selected. Genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism followed by electrophoresis in agarose gel. The evaluation of the cytokine concentration was performed by enzyme-linked immunosorbent assay. Statistical Analysis: Statistical calculations involved in this work include Chi-square test, Fisher Exact test, Mann-Whitney and Kruskal-Wallis tests. Results: Our findings revealed that: (i No statistically significant relationship between periodontitis and the polymorphism studied was observed; (ii no significant difference between the concentrations of IL1B in saliva between the case and control subjects and between the genotypes of these individuals and the concentrations of this cytokine. Conclusions: We conclude that, in the sample evaluated, the IL1B c. 3954C > T polymorphism did not present as an etiological factor for periodontitis.

    This paper examines family planning in Brazil as biopolitics and explores how the democratization of the State and of reproductive health services after two decades of military dictatorship (1964-1984) has influenced health professionals' and family planning users' discourses and practices. Do health professionals envisage family planning as a 'right' or do they conceive it, following the old neo-Malthusian rationale, as a 'moral duty' of poor people, whose 'irrational' reproduction jeopardizes the family's and the nation's well being? And how do their patients conceptualize and embody family planning? To answer these questions, this paper draws on 13 months of multi-sited ethnographic research undertaken between 2003 and 2005 in two public family planning services in Salvador da Bahia, where participant observation was undertaken and unstructured interviews were conducted with 11 health professionals and 70 family planning users, mostly low income black women. The paper examines how different bio-political rationalities operate in these services and argues that the old neo-Malthusian rationale and the current, dominant discourse on reproductive rights, gender equality and citizenship coexist. The coalescence of different biopolitical rationalities leads to the double stigmatization of family planning users as 'victims' of social and gender inequalities and as 'irrational' patients, 'irresponsible' mothers and 'bad' citizens if they do not embody the neo-Malthusian and biomedical rationales shaping medical practice. However, these women do not behave as 'docile bodies': they tactically use medical and non-medical contraceptives not only to be good mothers and citizens, but also to enhance themselves and to attain their own goals.

    Full Text Available Background: Schinus terebinthifolius is widely used in traditional medicine by Brazilian quilombola and indigenous communities for treatment of several diseases. Extracts from different tissues are being used to produce creams to treat cervicitis and cervicovaginitis. However, most studies are limited to the assessment of the essential oils and extracts obtained from the leaves. Objective: The aim was to evaluate antioxidant and antibacterial activities, to assess the phytochemical profile and to quantify total phenolic compounds of various extracts prepared from S. terebinthifolius grown in the coast of Bahia, Brazil. Materials and Methods: Extracts were obtained by hot continuous extraction (soxhlet and by maceration. Quantification of phenolic compounds was performed using the Folin Ciocalteu method and antioxidant properties were assessed by 2,2 diphenyl 1 picrylhydrazyl radical scavenging assay. Phytochemical screening was performed as described by in the literature and antibacterial activity against Enterococcus faecalis (ATCC 29212 was determined by the microdilution broth assay. Results: Extraction method greatly affected the metabolite profile of the extracts. Antioxidant activity varied between 21.92% and 85.76%, while total phenols ranged between 5.44 and 309.03 mg EAG/g of extract. Leaf extract obtained with soxhlet showed minimum inhibitory concentration (MIC of 15.62 μg/mL, while stem extract obtained by maceration was able to inhibit the growth of E. faecalis at 62.5 μg/mL. Stem bark extracts showed a MIC of 500 μg/mL for both extraction methods, while no inhibition was observed for fruit extracts. Conclusion: In general, total phenolic content, antioxidant and antibacterial activities were higher in samples obtained by soxhlet. Our results provide important clues in order to identify alternative sources of bioactive compounds that can be used to develop new drugs.

    Full Text Available Abstract The knowledge on diet composition of the freshwater mussel Diplodon enno (Ortmann would aid in its culture and propagation allowing, this way, the replacement of natural endangered populations in Brazil. Microalgae are the main food source for captive mussels and unionids have displayed an ability to sort algae based on the cellular characteristics prior to ingestion. The main objective of the present work is to analyze the phytoplankton composition of the water from and of the gastrointestinal contents of the mussel D. enno, as an initial step for development of a suitable rearing diet. Therefore, water samples and bivalve specimens were collected from S. Francisco River, city of Paulo Afonso, Bahia, Brazil. The microalgal composition found in water and stomach/gut content samples was very diverse being represented by the following divisions: Cyanophyta, Chlorophyta, Dinophyta and Heterokontophyta (Diatoms. Concerning the relative abundance of microalgae divisions, it is possible to state, for the water and gastrointestinal contents, that Cyanophyta represents 15% and 14%, Chlorophyta 54% in both, Heterokontophyta 31% and 27% and Dinophyta 0% and 5%, respectively. According to the Brazilian CETESB criteria for phytoplankton species classification, 50% of Cyanophyta and 15% of Chlorophyta species observed in the water samples were classified as “very frequent”, as were 68% of Heterokontophyta and 33% of Chlorophyta species in the gut/stomach tract samples. Focusing at a species level, although in the water only Coelastrum sp. and Chroococcus sp. were observed in 100% and 75% of the samples, respectively, in the gastrointestinal tract the species Staurastrum sp., Aulacoseira sp., Scenedesmus sp. and Fragilaria crotonensis occurred in 80% to 100% of the samples. The present results showed that D. enno feeds not only on small chlorophytes microalgae, due to their convenient size that facilitates higher feeding rates, but also on large

    Carbon and nitrogen stable isotopic signatures of suspended particulate organic matter and seawater biological oxygen demand (BOD) were measured along a coastal transect during summer 2015 to investigate pollution impacts of a high-discharge submarine sewage outfall close to Salvador, Brazil. Impacts of untreated sewage discharge were evident at the outfall site by depleted δ13Corg and δ15N signatures and 4-fold increased BOD rates. Pollution effects of a sewage plume were detectable for more than 6 km downstream from the outfall site, as seasonal wind- and tide-driven shelf hydrodynamics facilitated its advective transport into near-shore waters. There, sewage pollution was detectable at recreational beaches by depleted stable isotope signatures and elevated BOD rates at high tides, suggesting high bacterial activity and increased infection risk by human pathogens. These findings indicate the urgent necessity for appropriate wastewater treatment in Salvador to achieve acceptable standards for released effluents and coastal zone water quality.

    The economic growing in Brazil is responsible for an urgent demand for energy. Uranium is the fuel used to generate nuclear power. Brazil has the sixth largest reserve of the uranium ore in the world and, nowadays there is only one mine under exploration (Uraniferous District of Lagoa Real - Caetite-BA). Some Non-Governmental Organizations (NGOs), such as Greenpeace, state that the explored uranium mine is dangerous and polluting, causing water contamination by uranium. So, the population would be receiving radiation doses above permissible limits. However, Industrias Nucleares do Brasil (INB) the company in charge of the complex extraction and production of yellow cake rejected these accusations. The main purpose of this work is the determination of the composition of natural radionuclides in the Uraniferous District of Lagoa Real in order to determine if the nearest population is exposed to environmental radiation. It was checked if there is water contamination due to the natural transport in the uranium mining surroundings. Soil and water samples from Caetite mine and also from nearby town were collected. Only one water sample collected had concentrations higher than the limits recommended by World Health Organization. The presence of radionuclides in soil samples is considered independent of mineral exploration. The effective dose rates in almost all samples are above the world average which is 2.4 mSv/y. To sum up, the presence of uranium in water and soil of the tested areas is probably due to the nature of the soil and not to the exploration of mine. (author)

    Concentrations of elements (As, Ba, Cd, Co, Cr, Cu, Li, Mn, Ni, Pb, V, and Zn) were determined in ten species of macroalgae collected from six sites in the Todos os Santos Bay, Brazil, between May and July of 2010. An optimized microwave-assisted digestion procedure was used to digest the samples. The elements were determined by inductively coupled plasma mass spectrometry (ICP-MS). A wide range of metal concentrations were observed between the species analysed. Somewhat higher concentrations of Cd (5.99μg g(-1)), Co (372μg g(-1)), Mn (640μg g(-1)), Ni (17.2μg g(-1)) and Zn (51.4μg g(-1)) were found in the brown macroalgae species Padina spp., whereas elements, such as As (19.7μg g(-1)) and Pb (8.27μg g(-1)), were mainly concentrated in the species Sargassum spp. and Bostrychia montagnei, respectively. Statistical analyses (ANOVA) of the Padina data showed significant inter-site differences for all metals examined except nickel. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Urbanization is increasing across the globe, and diseases once considered rural can now be found in urban areas due to the migration of populations from rural endemic areas, local transmission within the city, or a combination of factors. We investigated the epidemiologic characteristics of urban immigrants and natives living in a neighborhood of Salvador, Brazil where there is a focus of transmission of Schistosoma mansoni. In a cross-sectional study, all inhabitants from 3 sections of the community were interviewed and examined. In order to determine the degree of parasite differentiation between immigrants and the native born, S. mansoni eggs from stools were genotyped for 15 microsatellite markers. The area received migrants from all over the state, but most infected children had never been outside of the city, and infected snails were present at water contact sites. Other epidemiologic features suggested immigration contributed little to the presence of infection. The intensity and prevalence of infection were the same for immigrants and natives when adjusted for age, and length of immigrant residence in the community was positively associated with prevalence of infection. The population structure of the parasites also supported that the contribution from immigration was small, since the host-to-host differentiation was no greater in the urban parasite population than a rural population with little distant immigration, and there had been little differentiation in the urban population over the past 7 years. Public health efforts should focus on eliminating local transmission, and once eliminated, reintroduction from distant migration is unlikely.

Only carapace length vs. pleura length in females presented a significant difference in the relative growth pattern, indicating a puberty moult. This relationship is strictly correlated to reproduction and its success rate in female shrimps. Estimated carapace length in 50% of mature females (CL50 was 4.53 mm. It was not possible to compare obtained CL50 results due to a lack of studies on this species. Comparison was based on the size of the smallest captured ovigerous female (3.81 CL mm, which is within the scope of recorded size for estuaries located in higher latitudes. This study reveals the lack of research on this genre in freshwater environments on a national and global scale.

    The Camamu and Reconcavo South Basins are located near the passive continental margin of the Bahia State, Brazil, and have high potential for hydrocarbon exploration. In these basins and surrounding basement, brittle and ductile structures were studied, which resulted in 3D stress field orientations by use of inversion methods. From this study, the following results are relevant: important control of the basement structural heritage on the basin formation and evolution; local strike-inversion of {sigma}{sub 1} and {sigma}{sub 3} orientations in transtensive settings; vertical {sigma}{sub 1} typical of extensional regime precedes sub horizontal {sigma}{sub 1} of transtensive one; in relation to basin's long axes, at least four main horizontal {sigma}{sub 1} orientations were obtained, involving parallel, orthogonal and two diagonal sets. This could be related to: parallel and orthogonal flexural stress due to the sedimentary load, local elastic rebound of fault blocks, stress channeling, density contrasts between oceanic and continental crusts and ridge pull of the adjacent oceanic plate; diagonals, due to a combination of first order regional and second order local stress fields. This suggest that the continental margin of the Bahia State evolves from a typical passive into a transtensive margin, with transpressive regime that have been observed in some places, in a classical evolution of the Wilson Cycle.

    Agroforestry systems (AFSs) have an important role in capturing above and below ground soil carbon and play a dominant role in mitigation of atmospheric CO(2). Attempts has been made here to identify soil organic matter fractions in the cacao-AFSs that have different susceptibility to microbial decomposition and further represent the basis of understanding soil C dynamics. The objective of this study was to characterize the organic matter density fractions and soil size fractions in soils of two types of cacao agroforestry systems and to compare with an adjacent natural forest in Bahia, Brazil. The land-use systems studied were: (1) a 30-year-old stand of natural forest with cacao (cacao cabruca), (2) a 30-year-old stand of cacao with Erythrina glauca as shade trees (cacao + erythrina), and (3) an adjacent natural forest without cacao. Soil samples were collected from 0-10 cm depth layer in reddish-yellow Oxisols. Soil samples was separated by wet sieving into five fraction-size classes (>2000 μm, 1000-2000 μm, 250-1000 μm, 53-250 μm, and 2000 μm) mixed with macroaggregates (32-34%), and microaggregates (1-1.3%). Soil organic carbon (SOC) and total N content increased with increasing soil size fraction in all land-use systems. Organic C-to-total N ratio was higher in the macroaggregate than in the microaggregate. In general, in natural forest and cacao cabruca the contribution of C and N in the light and heavy fractions was similar. However, in cacao + erythrina the heavy fraction was the most common and contributed 67% of C and 63% of N. Finding of this study shows that the majority of C and N in all three systems studied are found in macroaggregates, particularly in the 250-1000 μm size aggregate class. The heavy fraction was the most common organic matter fraction in these soils. Thus, in mature cacao AFS on highly weathered soils the main mechanisms of C stabilization could be the physical protection within macroaggregate structures thereby

    The use of ethnoecological tools to evaluate possible damage and loss of biodiversity related to the populations of species under some degree of threat may represent a first step towards integrating the political management of natural resources and conservation strategies. From this perspective, this study investigates fishermen's ecological knowledge about sea turtles and attitudes towards the conservation and bycatch in Ilhéus, Southern Bahia, Brazil. Fishermen experts semi-structured interviews were performed using snowball sampling method. The interviews consisted of a series of questions relating to the fishermen's profile, structure and work equipment, the local ecological knowledge of fishermen about sea turtles and bycatch, a projective test, attitudes towards turtle conservation and beliefs and taboos regarding turtles. Indicators for quantitative comparisons of respondents in terms of their broad knowledge and attitudes towards turtle conservation were created. Correlation analyses were made between indicators of knowledge and attitude as well as the relationship between education level and knowledge and attitudes. Thirty experts were interviewed for the study. The local ecological knowledge and attitudes of fishermen towards the conservation of sea turtles were respectively medium (0.43) and moderate (0.69) according to experts (based on Likert scale and Cronbach's Alpha). Potential areas of spawning were reported from Barra Grande to Una covering the entire coast of Ilhéus. Methods for identifying the animal, behavior, and popular names were described by fishermen. The most recent captures of turtles were attributed to fishing line, but according to the respondents, lobster nets and shrimp traps are more likely to capture turtles. Knowledge and attitudes were weakly inversely correlated (r = -0.38, p = 0.04), and the education level of the respondent showed a positive correlation with positive attitudes towards turtle conservation (H = 8.33; p = 0

    Blue sodalite syenite is a rare rock, and the Southern Bahia Alkaline Province (SBAP) is the only place in Brazil where economic deposits are found. This province forms part of the Archaean to Paleoproterozoic São Francisco craton, and contains a few batholiths, a large number of stocks and hundreds of dykes. Its southern part lies close to the tectonic contact between the craton and the Neoproterozoic Araçuaí mobile melt. Blue sodalite-bearing syenites are found in almost all the igneous bodies of the SBAP as dykes or pegmatitic masses hosted by nepheline syenite. Economically viable quantities for the production of dimension stones are found only in the Floresta Azul alkaline complex, the Itaju do Colônia and Rio Pardo stocks and the Itarantim batholith.U-Pb ages obtained for titanite from Itaju do Colônia (732 ± 8 Ma) and Rio Pardo (714 ± 8) and Pb-Pb evaporation ages of zircon from Floresta Azul (696 ± 3 Ma) and Itarantim (722 ± 5 Ma). The geochronology of the SBAP shows that the anorogenic alkaline magmatism persisted for at least 58 Ma, demonstrating an extensional tectonic environment in the southern part of the São Francisco craton at this time. The data show that the rift phase which preceded the formation of the Araçuaí orogen was active until at least 700 Ma. The reported ages are similar to those found for the nepheline syenite host bodies, which supports the conclusions of the previous petrologic study demonstrating that blue sodalite is formed during the crystallization of these bodies. Two different processes are involved. In the magmatic process, sodalite occurs as disseminated and interstitial crystals among alkali feldspar crystals, and is associated with calcite and cancrinite formed by destabilization of nepheline. In the metasomatic process, discontinuous bands of sodalite are in sharp contact with nepheline syenite pegmatite, and its crystal aggregates often contain relict textures of nepheline and albite been replaced by sodalite.

    In 2003, the Brazilian Regulatory Petroleum Agency (ANP) firmed an agreement with the Federal University of the Bahia (UFBA), transferring to the Polytechnical School the property of five mature fields in Bahia (Quiambina, Fazenda Mamoeiro, Caracatu, Bela Vista and Riacho Sesmaria). The objectives of the agreement, some already reached, were: the revitalization of the fields, the development of technology for gas and oil extraction, the training of professionals. To reach the goals, the Field-School Project (PCE) was created. It is responsible for the control of the activities directly related to the revitalization of the wells. Other activities were also carried out by the PCE: formalization of an agreement between the UFBA and the Brazilian Institute of Oil (IBP) for scientific, academic and cultural activities; creation of a site (www.campoescola.ufba.br), in which interesting information to the oil area is available; consulting to small groups interested in exploring mature fields; increase of resources and job offers to the communities and to the cities near the places were the wells are located; participation in events.

    At the region of Caetite, BA, it is located the largest uranium mine in exploration at present days in Brazil. During the uranium extraction process, it may be having an environmental contamination by this heavy metal due to rain water and other natural transport mechanism, with potential exposition risk to the local population. The aim of this work was to investigate the total uranium concentration in surface and underground water samples collected at the Caetite region, using the nuclear track registration technique (SSNTD) in a polycarbonate plastic. A 100 mL volume of water samples were initially treated in 10 mL of HNO{sub 3} (PA) and concentrated by evaporation at a temperature around 80 deg C. The resulting residue was diluted to a total volume of 25 mL without pass it to a filter. About 10 {mu}L of this solution was deposited on the plastic detector surface (around 1.0 cm{sup 2} area) together with 5 {mu}L of a Cyastat detergent solution (5%) and evaporated under an infrared lamp. All the resulting deposits of non volatile constituents were irradiated, together with a uranium standard sample, at the IPEN-IEA-R1 (3.5 MW) nuclear reactor for approximately 3 min. After irradiations, chemical etching of the plastic detectors was carried out at 60 deg C, for 65 min. in a NaOH (6N) solution. The fission tracks were counted scanning all the deposit area of the polycarbonate plastic detector with a system consisting of an optical microscope together with a video camera and TV monitor. The average values of uranium concentrations obtained in this work ranged from (0.95{+-}0.19) {mu}g.L{sup -1} to (25.60{+-}3.3) {mu}g.L{sup -1}. These results were compared to values reported in the literature for water samples from other regions and discussed in terms of safe limits recommended by WHO -World Health Organization and CONAMA - Conselho Nacional do Meio Ambiente.

    Full Text Available OBJECTIVE: This study aimed to determine the maternal meanings attributed to breastfeeding during the child's first two years of life. METHODS: This qualitative, exploratory and analytical study involved mothers that participated in a cohort from a larger study done in the municipalities of Mutuipe and Laje in the Recôncavo area of the State of Bahia, Brazil. The methodological resources included thorough individual interviews and thematic analysis. The meanings were analyzed by the theoretical framework of sociological phenomenology. RESULTS: The meanings stated by the mothers show the singularity of breastfeeding, the importance of family, spousal and health practitioner support, and knowledge about the benefits of breastfeeding for the mother's and child's health and nutritional status. CONCLUSION: The meanings attributed to breastfeeding in the child's first two years of life reflected the influences of complex networks of social relationships of the mother's social and cultural context and of the scientific and biomedical discourse.

  2. Evolution of garnet distribution, shape and composition in high-grade pelitic migmatites of Salvador da Bahia, Brazil: insights from LA-ICP-MS trace element mapping

    Garnet is a widely used mineral in metamorphic petrology and more particularly for thermobarometric modelling to reconstruct the P-T-t evolution of Earth's crust. This is due to its ubiquity in high grade rocks (T > 450°C), its occurrence in many assemblages of interest for thermobarometry, and mostly to its ability to preserve chemical zoning. Two types of zoning are distinguished: growth and diffusion zoning. Growth zoning reflects crystallisation coeval with changes in P-T conditions or bulk composition. This type of zoning is therefore particularly useful to unravel the P-T evolution of open systems and determine the growth mechanisms involved. However, growth zoning in major elements is commonly altered by processes such as volume diffusion, which is particularly efficient at high temperatures and for elements like Fe or Mg that have high diffusion coefficients. In such cases, information that relates to the environmental conditions of garnet growth is either totally or partially obliterated. To minimise the impact of this process on growth zoning and retain useful information, trace elements are more appropriate because of their lower diffusion coefficients compared to major elements. In this study, the distribution of trace elements in garnet has been imaged using an emerging LA-ICP-MS mapping technique. This is achieved by rastering of the focused laser beam in linear transects, which are then stitched together by post-acquisition processing to form a quantified or semi-quantified image of the trace element distribution, with excellent detection limits (ppb) over a wide isotopic range (7Li to 238U) and minimal sample preparation required. This technique has been applied to high-grade pelitic gneisses and migmatites from the Paleoproterozoic Itabuna-Salvador-Curaça belt (adjacent to the Farol da Bara, Salvador da Bahia, Brazil). Structurally, it is located in a steeply-dipping high strain zone that may have played a major role in the segregation and

    In the present research, the proposal was to develop a preliminary study about the geochemical behavior of determined chemical elements, mainly the uranium, during the action of weathering processes in the rocks that bear the uranium mineralizations of the Caetite-Lagoa Real region, State of Bahia, more specifically of the Jazida Cachoeira uranium mine. To reach this purpose were used samples that represent several stages of the milling process of the uranium ore, so selecting representatives of the host rock, the ore and the treated ore (waste from the milling plant) to be used in the laboratory-controlled experiments. The samples were dried, sieved and finally introduced in the reactors, these adapted from the Flow-Through Reactor of Brantley and Chen. In the geochemical point of view, the results of the experiments showed a distinct behavior between the samples. It was observed that the treated ore, in relation to the host rocks of the ore and the own ore, shown a faster and homogeneous interaction with the leaching solution; it was also noted that in the output solution of the treated ore samples existed a significant complexation of the uranium by the sulfate (S0{sub 4}{sup -2}), ), instead of the non treated samples (host rock and ore) that were complexed mainly by the carbonate (C0{sub 3}{sup -2}). These different results are attributed to the alterations imposed to the rock during the milling process, and occur mainly, during the acid attack in the leaching process of the milling plant. The results and conclusions of this research, in spite of been preliminary, are essential to understand the behavior of the geochemical speciation of the effluent solutions; to understand the alterations of a rock matrix, and finally, to understand the migration chemical behavior of the related chemical elements. It is expected that these results contribute, in the future, to a deeper knowledge of the processes that control the chemical composition of the natural waters from

Aspecto importante para a compreensão da epidemiologia do dengue nos dias atuais refere-se ao conhecimento dos padrões da difusão espaço-temporal, entretanto são escassas as investigações que abordam esta questão. Este estudo descreve o processo de difusão do dengue no estado da Bahia, de 1994 a 2000. MÉTODOS: Trata-se de estudo ecológico espaço-temporal, tendo como unidades de análise município, semana epidemiológica, mês, trimestre e ano. Procedeu-se construção da curva de tendência e realizou-se mapeamento seqüencial da ocorrência de dengue por município para o período. RESULTADOS: Foram notificados 164.050 casos de dengue e a introdução desse vírus na Bahia, diferentemente de outros estados, se deu por um município de pequeno porte, constatando-se intermitência temporal e espacial nos registros de casos no início desta epidemia. Contudo, a partir de 1995 o processo de difusão da doença se deu de forma rápida e intensa. O vírus circulou em todas as zonas climáticas do estado o que revela o seu elevado poder de transmissão. A maior intensidade de detecção de casos e expansão territorial foi nas regiões úmidas e semi-úmidas do litoral, ideais para a sobrevivência e proliferação do vetor, e também, por serem mais densamente povoadas. CONCLUSÕES: Hipoteticamente, o padrão espaço-temporal intermitente de detecção de casos observado inicialmente, poderia permitir o controle da progressão da epidemia, caso houvesse ações de combate vetorial estruturadas.INTRODUCTION: The strength of the re-emergence of dengue virus and the severity of these infections put this disease in the priority agenda of the institutions responsible for protecting the health of populations.

It is not clear whether there is an association between etiology and pulmonary pressure level or symptom intensity. OBJECTIVES: 1 to describe the etiological prevalence of PH in the state of Bahia, Brazil; 2 to evaluate whether the etiology is a determinant factor for the pulmonary pressure level; 3 to evaluate whether the etiology is a determinant factor for functional class; 4 to identify the other predictors of pulmonary pressure level and functional class. METHODS: The present was an observational, cross-sectional study that analyzed individuals with PH treated at the Magalhaes Neto Outpatient Clinic, between June 2005 and December 2007. PH was defined as pulmonary artery systolic pressure (PASP > 40 mmHg measure at the echocardiogram. Patients with chronic obstructive pulmonary disease or ventricular disease were excluded from the study. RESULTS: A total of 48 patients with PASP = 86 ± 24 mmHg were studied. Regarding the etiology, 42% of the patients were classified as idiopathic, followed by 25% as schistosomatic, 19% as congenital cardiopathy and 10% of chronic pulmonary embolism. A longer time of disease predicted higher pressures in patients with cardiopathy. Individuals with schistosomiasis had the best functional performance when compared to the others (456 ± 58 vs. 299 ± 138 meters, p=0.005. The schistosomatic etiology and younger age presented better functional class. CONCLUSIONS: 1 the idiopathic classification is the most prevalent, with schistosomiasis being the most frequent specific cause in our country; 2 patients with schistosomatic etiology and of younger age present better functional class. 3 the congenital cardiopathy results in a higher pressure level in the pulmonary artery, probably due to the longer duration of the disease.

    The municipality of Ilhéus, State of Bahia, has a focus of cutaneous leishmaniasis where entomological studies were carried out to determine the sand fly species and their habits. Lutzomyia migonei, L. sallesi, L. tupynambai, L. schreiberi, L. intermedia, L. whitmani, L. yuilli yuilli, L. fischeri, L. pessoai, L. shannoni and L. misionensis were identified. Lutzomyia whitmani was the predominant species. Specimens were collected indoors, at peridomestic sites, in the cocoa plantations and in other types of collections. Females fed readily on humans and were attracted to domestic animals. Our evidence suggests that L. whitmani is a probable vector.

    Triatomine surveillance in rural areas, artificial ecotypes, and natural ecotopes of the cities of Caturama, Ibipitanga, Macaúbas, and Seabra in the south-central region of the Brazilian state of Bahia was carried out between 2008 and 2013. Natural infection by Trypanosoma cruzi was evaluated in the specimens collected to monitor vectors of Chagas disease. A total of 1,357 specimens were collected, and four species were identified: Triatoma sordida (83%), Triatoma lenti (16.4%), Triatoma pseudomaculata (0.5%), and Panstrongylus geniculatus (0.1%). Triatoma sordida was found in four cities, only 0.7% in intradomiciliary environments. Triatoma lenti was found only in Macaúbas; 8.5% were found in intradomiciliary environments, 88.3% in peridomiciliary environments, and 3.1% in sylvatic environments. Natural infection by T. cruzi was 0.5% for T. sordida and 3.1% T. lenti. All of these cases were found in peridomiciliary environments of Macaúbas. As the results show, triatomines were found in intradomiciliary environments in three cities that were surveyed in the south-central region of the state of Bahia. Thus, an epidemiologic survey should be performed to avoid the risk of transmission to the population.

    Full Text Available Recent geological, geochronological and isotopic research has identified four important Archean crustal segments in the basement of the São Francisco Craton in the State of Bahia. The oldest Gavião Block occurs in the WSW part, composed essentially of granitic, granodioritic and migmatitic rocks. It includes remnants of TTG suites, considered to represent the oldest rocks in the South American continent (~ 3,4Ga and associated Archean greenstone belt sequences. The youngest segment, termed the Itabuna-Salvador-Curaçá Belt is exposed along the Atlantic Coast, from the SE part of Bahia up to Salvador and then along a NE trend. It is mainly composed of tonalite/trondhjemites, but also includes stripes of intercalated metasediments and ocean-floor/back-arc gabbros and basalts. The Jequié Block, the third segment, is exposed in the SE-SSW area, being characterized by Archean granulitic migmatites with supracrustal inclusions and several charnockitic intrusions. The Serrinha Block (fourth segment occurs to the NE, composed of orthogneisses and migmatites, which represent the basement of Paleoproterozoic greenstone belts sequences. During the Paleoproterozoic Transamazonian Orogeny, these four crustal segments collided, resulting in the formation of an important mountain belt. Geochronological constrains indicate that the regional metamorphism resulting from crustal thickening associated with the collision process took place around 2.0 Ga.

    This article is based on an assessment that indicates the low effectiveness of the actions and programmes of social responsibility to the less impact than in business and should not build the value they expected. Focussing on this issue in cases of relationship between oil and gas companies with fishing communities, the scene of conflict is chronic and there is a fragile relationship in terms of confidence. It has been further that the approaches and methods commonly used are not properly aligned to the realities and characteristics of artisanal fisheries. In this context, we present an innovative process of relationship between the company El Paso Oil and Gas of Brazil and fishing communities in the region of Baixo-Sul, Bahia. The strategy used effectively consolidated the relationship of confidence between the company and the fishing communities around the area of exploration, rescuing the self-esteem, alleviate the marginalisation and making visible a productive sector of extreme importance. Furthermore, the capabilities and skills, both communities as the government and other companies to take more solid and ongoing commitments in the process of co-management require specific efforts in the strengthening of an institutional arrangement and the formation of social capital to continue advancing in concept work.

    Full Text Available Freshwater crabs are key elements of the aquatic biota of streams, rivers, lakes, and dams because of their ecological and economic importance. Considering that Trichodactylus fluviatilis (Latreille, 1828 is an important source of food for the human settlements that inhabit the places of its occurrence, this article records, for the first time, an ethnocarcinological study carried out with the inhabitants of Pedra Branca county, Bahia State. Data were obtained from February to June 2005 by means of open-ended interviews using the usual techniques of ethnographical survey. Sixteen women and eleven men were interviewed. Their ages ranged from 25 to 86 years old. The results showed that the ethnocarcinological knowledge about T. fluviatilis is relatively consistent with academic knowledge. Ethnozoological studies that stress the cultural significance of freshwater crustaceans are very important, since they would represent a great contribution to the debate on biodiversity conservation in the environments these animals inhabit.

    Full Text Available The goal of the present work was to investigate the occurence of canine Visceral Leishmaniasis (VL in Itapuã, Cajazeiras and Pau da Lima sanitary districts (SD, all belonging to the city of Salvador. In order to achieve it, a canine epidemiological and entomological surveys were applied as an epidemiological questionnaire to the owners of the animals sampled and to the veterinary physicians of the city. The study detected six VL seropositive dogs among the eight hundred and eleven ones randomly sampled. It was not possible to determine the autoctonous condition for L. chagasi infection. One animal was positive by culture of splenic material and in the entomologic survey of the vector, Lutzomyia longipalpis, none was captured. Veterinary clinicians from 41.7% of the clinics evaluated reported the diagnostic of, at least, one VL case in Salvador domiciliated dogs. The SD of Itapuã, Cajazeiras and Pau da Lima presented VL transmission risk once there is Leishmania parasite occurrence in the municipality, verified in this study by splenic culturing of an animal aspirative puncture, previous record of vector (L. longipalpis presence in the Itapuã district by the Bahia State Health Agency (SESAB and canine VL diagnostics by veterinary doctors from clinics all around the city of Salvador. This work is the first epidemiological analysis of this zoonosis in these SD and they point out the need to perform sampled entomological and serological surveys in all areas of the city. The development of a VL surveillance system may contribute for monitoring the disease in Salvador.Objetivou-se com este estudo investigar a ocorrência da Leishmaniose Visceral (LV canina nos Distritos Sanitários (DS de Itapuã, Cajazeiras e Pau da Lima, pertencentes ao município de Salvador, por meio da realização de inquérito sorológico canino; inquérito entomológico, aplicação de questionário epidemiológico aos proprietários dos animais amostrados e a m

This study describes the labor conditions of private school teachers in Vitória da Conquista, Bahia State, Brazil. Information on 250 teachers from the ten largest schools in the municipality was collected through a self-applied questionnaire. The most relevant characteristics of teachers' work, evaluated by the Job Content Questionnaire were: speed of work, creativity at work, and relations with colleagues. The most frequent complaints related to posture, mental strain, and voice problems. Prevalence of minor psychological disorders according to the Self Reporting Questionnaire-20 was 41.5%, strongly associated with long periods of intense concentration on the same job and excessive work.

    Full Text Available O artigo apresenta estudo do acondicionamento e coleta de resíduos sólidos domiciliares e o impacto na saúde de crianças, por meio de pesquisa realizada em nove assentamentos humanos localizados em área periurbana da cidade de Salvador, Bahia, Brasil. Como indicadores epidemiológicos foram utilizados, em 1.893 crianças entre 5 e 14 anos, a infecção por nematóides intestinais, expressa pela prevalência de Ascaris lumbricoides, Trichuris trichiura e ancilostomídeos, e em 1.204 crianças menores de cinco anos, a incidência de diarréia e o estado nutricional, este expresso por indicadores antropométricos. Os resultados apresentam a maior prevalência dos três nematóides nas crianças dos domicílios que não dispõem de acondicionamento adequado e de coleta de resíduos sólidos que naquelas de domicílios com acondicionamento adequado e coleta regular, sendo a diferença encontrada estatisticamente significante, mesmo quando outros fatores de risco sócio-econômicos, culturais, demográficos e ambientais são considerados. Resultado semelhante é também observado com relação aos indicadores epidemiológicos, incidência de diarréia e estado nutricional.This paper presents a study on the bagging and collection of household solid waste and the health implications for children. The research was conducted in nine human settlements on the outskirts of Salvador, Bahia State, Brazil. Intestinal nematode infection, predominantly involving Ascaris lumbricoides, Trichuris trichiura, and hookworms, was used as an epidemiological indicator in 1,893 children from 5 to 14 years of age. The study also included diarrhea incidence and nutritional status as shown by anthropometric indicators in 1,204 children less than 5 years of age.

    Full Text Available Este artigo examina o parto em uma maternidade pública de Salvador, Bahia, Brasil, com base na perspectiva de mulheres jovens e adolescentes, a maioria das quais negras e de classes populares. O estudo, de caráter antropológico, baseia-se na análise de entrevistas e na etnografia do hospital, particularmente do centro obstétrico. As mulheres descrevem o trabalho de parto como dominado pelo medo, solidão e dor, sensações que se transformam em amor com o nascimento da criança. Enfocando o parto como um processo biossocial, o trabalho mostra como as jovens produzem significados durante o processo de parturição, enquanto se encontram envolvidas nas interações sociais próprias ao parto hospitalar, particularmente com os profissionais de saúde. Do ponto de vista simbólico, as parturientes experienciam o parto como um rito de passagem que legitima a maternidade, em um contexto social e institucional que, ao contrário, deslegitima a reprodução sexual de mulheres negras, jovens e de baixa renda e estigmatiza a maternidade na adolescência.This article examines childbirth in a public maternity hospital in Salvador, Bahia, Brazil, from the perspective of young and adolescent women, mostly black and working-class. As an anthropological study, it is based on the analysis of birth narratives and hospital ethnography, especially in the obstetric ward. The women describe labor as dominated by fear, loneliness, and pain. These feelings are transformed into love with the birth of the child. Viewing childbirth as a biosocial process, the authors show how the young women construct meanings during the birth; meanwhile, social interactions specific to hospital birth develop, particularly with healthcare professionals. Symbolically, women construct birth as a rite of passage legitimating motherhood, against the institution's effective de-legitimization of sexual reproduction in low-income black mothers and stigmatization of adolescent motherhood.

    Full Text Available Kappaphycus alvarezii, uma das principais fontes de matéria prima para produção de carragenana, vem sendo cultivada em balsas flutuantes, na baía de Sepetiba, sem estudos de monitoramento ambiental. A ocorrência e o estabelecimento de esporos e de mudas desta alga exótica no ambiente marinho foram avaliados e a praticidade da metodologia aplicada foi verificada, visando à proposta de um protocolo de monitoramento ambiental para cultivos liberados para o Brasil, entre a baía de Sepetiba (RJ e a Ilha Bela (SP. Este estudo foi realizado no maior cultivo desta espécie no país, na baía de Sepetiba (23º03'50"S e 043º52'50"N, entre maio e julho/2006. Neste período, não foi observada ocorrência de mudas férteis sob cultivo tampouco estabelecimento de esporos. A ocorrência de mudas fora do sistema de cultivo foi ínfima, frente à biomassa cultivada, e restrita aos limites da fazenda marinha. Além disso, a sobrevivência de mudas transplantadas fora das balsas foi suprimida em detrimento da baixa incidência luminosa provocada pelo alto teor de material particulado em suspensão na água do mar. Concluiu-se, portanto, que a introdução de Kappaphycus alvarezii não ocasionou danos ambientais nesta baía até o momento e que o método utilizado foi adequado à avaliação do estabelecimento desta espécie no ambiente. Neste sentido, recomenda-se a aplicação permanente do método apresentado como protocolo para o cultivo de Kappaphycus alvarezii na área permitida para o Brasil, visando à manutenção da biodiversidade marinha.Kappaphycus alvarezii, one of the most important sources of raw material for carrageenan production, has been cultivated in a floating-raft system, at Sepetiba Bay, southeast Brazil, with no environmental monitoring studies.

    Full Text Available Brazil was the first country in Latin America to establish and regulate this type of reserve, and there are currently more than 700 Private Nature Heritage Reserves (RPPN in Portuguese officially recognized by either federal or state environmental agencies. Together, these RPPN protect more than a half million hectares of land in the country. The coastal forests in the southern part of Bahia State extend 100 to 200 km inland, gradually changing in physiognomy as they occupy the dryer inland areas. The coastal forest has been subjected to intense deforestation, and currently occupies less than 10% of its original area. For this work the creation processes of the RPPN were consulted to obtain the data creation time, size of property, the condition of the remaining forest, succession chain and the last paid tax. After that, interviews with the owners were made to confirm this data. Sixteen RPPN have been established in this region until 2005. Their sizes vary from 4.7 to 800 ha. Ten of these RPPN are located within state or federal conservation areas or their buffer zones. In spite of the numerous national and international conservation strategies and environmental policies focused on the region, the present situation of the cocoa zone is threatening the conservation of the region's natural resources. The establishment of private reserves in the cocoa region could conceivably improve these conservation efforts. This type of reserve can be established under a uniform system supported by federal legislation, and could count on private organizations.O Brasil foi o primeiro País na América Latina a estabelecer e regulamentar este tipo de reserva e hoje, há mais de 700 Reservas Particulares do Patrimônio Natural (RPPN oficialmente reconhecidas pelos órgãos ambientais federais ou estaduais.

As estratégias metodológicas consistiram no censo dos médicos de saúde da familia da Bahia, Brasil; observações de consultas de vinte médicos de três municípios, orientadas por um instrumento. Os resultados indicam diferenças significativas entre a implementação do PSF nos três municípios, repercutindo na relação médico-paciente. Quanto à orientação das práticas, a vigilância da saúde não tem sido incorporada pelos médicos observados. A análise microcontextual apontou que os problemas de saúde freqüentemente não eram tratados de modo contextualizado. Compreende-se que as diretrizes do PSF, quando assumidas pelos municípios, são produtoras de diferenças na assistência observáveis no microcontexto da relação médico-paciente. A abordagem da vigilância da saúde, referida como ferramenta para o trabalho coletivo, mostra-se eficiente para descrever, avaliar e aperfeiçoar o PSF e, neste estudo, conclui-se que esta é uma ferramenta conceitual potencial para implementação da relação médico-paciente.This study discusses the physician-patient relationship under the Family Health Program (FHP in Bahia State, Brazil.

The Family Health Units showed better performance, due to measures for patient reception and referral to specialized services, but they revealed problems with scheduling of appointments. Despite having defined primary care as the portal of entry into the system and the implementation of a help desk for setting appointments with specialists, there are

    Full Text Available Desde 1996, o Brasil mantém políticas internacionalmente conhecidas como de acesso universal ao tratamento especializado em HIV/AIDS. Observa-se, que o impacto da iniciativa tem sido desigual entre diferentes populações e regiões brasileiras. Desde uma perspectiva de gênero, o estudo buscou avaliar o acesso a um serviço especializado em HIV/AIDS localizado em Salvador, Bahia, identificando fatores facilitadores e obstaculizadores ao acesso e continuidade do uso vivenciados por mulheres vivendo com HIV/AIDS. Foram realizadas observação participante e entrevistas semi e não estruturadas com 13 usuárias. Resultados indicaram que a organização das rotinas do serviço e as relações travadas entre usuários e entre eles e trabalhadores em saúde condicionavam-se por valores, concepções e práticas associados a gênero, classe e aparência. O acesso e continuidade do uso no Serviço de Atenção à AIDS de Salvador eram condicionados à disponibilidade de bens sociais e simbólicos; o serviço apresentava capacidade limitada de adequação às especificidades dos usuários. Os achados apontam para limitações da operacionalização das políticas de acesso universal; e reforçam a necessidade de estudos que considerem a noção de vulnerabilidade e regionalização da epidemia no Brasil.Since 1996, Brazil has implemented internationally acknowledged policies such as universal access to specialized treatment for HIV/AIDS. However, the initiative's impact has been unequal if one compares different population segments and regions of the country. Taking a gender perspective, the current study seeks to evaluate access to a specialized HIV/AIDS service in Salvador, Bahia, identifying facilitating factors and obstacles to access and continuity of care, as experienced by women living with HIV/AIDS. Participant observation and semi-structured and open-ended interviews with 13 women were used. The findings indicate that the organization of

    This study sought to estimate the prevalence of the combination of Body Mass Index (BMI) plus Waist Circumference (WC) and of BMI plus Waist to Height Ratio (WHR) and to investigate associated factors. A two-stage random sample of adults (>20 years) living in former African slaves communities (Quilombos) was taken in Vitória da Conquista in the State of Bahia in 2011. Combined BMI+WHR nutritional risk was defined by the simultaneous presence of BMI > 25.0Kg/m2 or > 27.0Kg/m2, if aged > 60 years and WHR > 0.5. BMI + WC nutritional risk was defined by elevated BMI in addition to WC > 80cm for women, or > 94cm for men. Among the 739 participants, the prevalence of combined nutritional indicators were 35.3% (BMI + WHR) and 26.8% (BMI + WC). Female sex and hypertension increased the chances of a combination of both indicators, while being unmarried decreased the chances. The prevalence of BMI + WHR was higher in the 40-59 year age range and the prevalence of BMI + WC was higher in the 40-49 year age range. Less schooling increased the chances of the combined BMI + WHR indicator and watching television for more than two hours/day increased the chances of the BMI + WC indicator. The high prevalence of combined nutritional indicators indicate the need of diet promotion actions to prevent obesity.

    The study seeks to investigate factors associated with HIV infection among adolescents and young adults registered in the Counseling and Testing Center (CTC) of Feira de Santana, Bahia. An analytical study with a cross-sectional design was conducted using data from the CTC Information System in the period from 2007 to 2011. Information on 3,768 individuals were studied and the proportional difference was checked using the Pearson chi-squared test and stratified analysis by Prevalence Rate (PR) with confidence intervals of 95%, considering the serological status as the outcome. During the period under study, 73 young people were infected with HIV (1.94%). In the female population, statistically significant associations were identified for HIV status and drug use and consumption of alcohol and other drugs, as well as being married or in a stable relationship. In males, the consumption of other drugs and homosexual/bisexual orientation were associated with HIV status. In both sexes, in the category in a stable relationship the HIV status was associated with a partner using drugs and/or infected with a STD and/or HIV. These findings indicate the need for effective measures for the control and prevention of HIV infection among young people.

    In recent years, important structural and institutional transformations are observed, for consequence the questions on the energy industries had started to incorporate, the regulation problems. Thus, the simple creation of new regulating agencies does not assure the automatic fulfilment of the functions of public interest. In this new context, these tasks are much more complex, demanding a learning process: how much to the structures of market and how much to the strategical behavior of the companies. In the local scene, to consolidate the distribution of the natural gas for the residential segment is one of the challenges of the Bahiagas, mainly after the publication of the Resolution that will go to establish the General Conditions of Gas Supply Canalized in the Residential Classroom in the State of the Bahia (hearing publishes carried through N. 002/2006 in June/2006). In this context, it is important to deeply understand the Resolution, that consequently will go to print a new dynamics for the Bahiagas. (author)

    The Brazilian environmental law requires oil companies' commitment to implement environmental programs, among which the environmental education project. This type of project should be understood by the companies as an opportunity for the development of socio environmental responsibility policies towards the affected populations. In order for the environmental education project to be effective as a means of awareness and social transformation, it is required to increase public's participation from the process of knowledge creation on the communities environmental problems to the disclose of the produced contents. This work refers to the use of the audiovisual as an instrument for the mobilization and consciousness for the construction of participative diagnostics, from the experience of the Environmental Education Project of the Polvo field, accomplished in ten municipal districts of the Campos Basin region. Inspired on an original methodology, the project promoted environmental cinema workshops that resulted in 30 documentaries directed by the local population and 10 environmental forums in which were developed local audiovisual environmental agendas.

    Full Text Available This study describes the temporal evolution of mortality due to traffic accidents in regions within Bahia State, Brazil, from 1996 to 2007, using data from the Brazilian Mortality Information System. We calculated overall rates of mortality due to traffic accidents and specific rates by type of victim. Temporal evolution was analyzed by means of correlations between rates and years of study, as well as polynomial regression models to evaluate trends. During the study period, the regions analyzed accounted for 60% of deaths due to traffic accidents in Bahia. Excess mortality among males and superior percentage of deaths in young individuals were observed. Overall, the evolution of global rates showed decreases beginning in 1998, but growth resumption in 2000, although the trend was not statistically significant. Regional differences were more marked when analyzing rates according to type of victim. However, a growing trend was observed in most locations for rates of accidents involving motorcyclists, which, in conjunction with other findings, substantiates concerns regarding the current situation of increased deaths involving motorcycles in Brazil.El estudio describe la evolución temporal de la mortalidad por accidentes de tráfico en regiones de Bahía, entre 1996 y 2007, a partir de los datos del Sistema de Información sobre Mortalidad.

    -GL of the State of Bahia, Brazil, was carried out in 2001 and the citrus root system in such soils was evaluated in order to determine attributes that best identify the cohesive layer. The first four horizons in each soil were sampled for analysis of particle size distribution, soil bulk density, total porosity, macroporosity, microporosity, and saturated hydraulic conductivity. Soil resistance to penetration and critical humidity of soil resistance to penetration were determined. Citrus root samples were collected in the same horizons and the results were expressed in cm cm-³ of soil. The citrus root system density reduced abruptly in the AB, Bw1, BA, and Bt1 horizons, and this was associated to soil cohesion. The best attribute to identify cohesion was soil resistance to penetration, which should be evaluated at soil humidity below the critical level to express cohesion. Saturated hydraulic conductivity was another attribute that proved appropriate to evaluate soil cohesion. It can be substituted by macroporosity, which is equally important to identify cohesion, with less variability besides being easier to measure than saturated hydraulic conductivity. Soil bulk density can be considered an attribute to evaluate the presence of cohesive horizons, but its use is limited mainly by the interference of particle size in its determination. The recommended indicators allow the detection of the presence of cohesive layers, orienting additional soil management practices to overcome the problems that such soils present for deep root growth.

Initially, eight adult and eight sapling individuals were selected and marked. In September/October, 2004 and April, 2005 eight leaves for each adult and three leaves for each sapling individual were collected and analyzed. In general, the area of leaves, rachis and leaflets, the length of rachis, the width of leaves, the number of pinnes and the dried mass of leaves were significantly higher in young individuals. Notwithstanding, the specific mass of leaves and leaflets were significantly higher in the adults. For both, adults and saplings, strong relationships were observed between the leaf dried mass and leaf area. Based on the results, we conclude that the leaves of C. echinata present characteristics that allow the maximization of light absorption in environments in which light radiation is a limiting factor, at the same time allocating carbon to the support tissues. The results obtained in the present study were in accordance with the successional status of this tree species and its strategies to occupy small canopy gaps of the semidecidual forest environments.

Os pescadores de Barra desenvolvem suas atividades habituais às margens dos rios São Francisco e Grande. O trabalho de campo foi realizado no período de janeiro a junho de 2000. Foram consultados 15 informantes (10 homens e 5 mulheres através de entrevistas livres e semi-estruturadas com o objetivo de registrar os aspectos cognitivos (etnotaxonomia, reprodução, comportamento, ecologia trófica, hábitat e culturais (restrições ao consumo de peixes e usos na medicina popular relacionados com as espécies de peixes locais. Dezoito espécies foram coletadas, identificadas e encontram-se depositadas no Laboratório de Ictiologia da Universidade Estadual de Feira de Santana. Os resultados revelam que os pescadores ainda possuem conhecimentos teóricos e práticos importantes que devem ser considerados em estudos de manejo, conservação e uso sustentável dos recursos pesqueiros. Problemas ecológicos de origem antrópica, tais como pesca predatória e introdução de espécies exóticas, vêm afetando o modo de vida dos pescadores tradicionais, tanto os da cidade de Barra como os das áreas adjacentes.This paper deals with the traditional ichthyological knowledge of fishermen’s community from the city of Barra, which is located in the west region of Bahia State, Northeast Brazil.

The study comprised 160 patients with severe asthma, monitored for 180 days in order to evaluate adherence (dependent variable to the prescribed inhaled corticosteroid. Independent variables were assessed at baseline and for a six-month follow-up period by means of interviews and the completion of a standardized questionnaire.Patients recorded the missed doses in a diary. RESULTS: Of the 160 patients. 158 completed the study. Adherence rate was 83.8%. Of the 158 patients, 112 (70.9% were considered adherent (cut-off point: 80% of prescribed doses administered. There was a significant association between asthma control and adherence to treatment.Predictors of poor adherence were adverse effects, living far from the referral center, limited resources to pay for transportation and dose schedule. Other factors, such as depressive symptoms, religion and economic status, were not associated with poor adherence. CONCLUSIONS: Adherence to asthma treatment was high and was associated with the clinical response to treatment, in a sample of patients with severe asthma enrolled in a public program that provides free medication and the assistance of a multiprofessional specialized team in a referral center

A proclamação da República marcou a fase inicial de modernização das empresas de transporte, em que a fusão de companhias e a incorporação de capitais estrangeiros possibilitaram a introdução dos bondes elétricos na capital baiana. Foi nesse contexto que dois grupos rivais iniciaram mais uma batalha no Brasil, agora pelos mercados de Salvador: de um lado, o grupo nacional da Companhia Brasileira de Energia Elétrica, e de outro lado, o grupo estrangeiro Light, liderado em Salvador pelo empresário norte-americano Percival Farquhar. Diante desse cenário de concorrência, o artigo analisa a relação entre as empresas e a Câmara Municipal de Salvador, instituição responsável por distribuir as concessões de transporte na cidade.This paper draws on the history of the formation of Salvador's city tramways between 1849 and 1930. The Proclamation of the Republic in Brazil (1889 started the modernization of the tramway companies which, through the merger of enterprises and the arrival of foreign capital, was responsible for the introduction of the electric tramways in Bahia's capital. Two rival groups, in this context, competed in the Brazilian market, now in Salvador: on the one hand, the national enterprise Companhia Brasileira de Energia Elétrica, and on the other, the foreign company Light, led by the North-American entrepreneur Percival Farquhar. In this context of competition, the paper analyses the relation between the enterprises and Salvador's Town Council, the institution responsible for tramway concessions in the city.

    Currently, hospital infection is a serious public health problem, and several factors may influence the occurrence of these infections, including the presence of insects, which are carriers of multidrug-resistant bacterial species. The aim of this study was to isolate staphylococci carried by insects in two public hospitals of Vitoria da Conquista, Bahia and to identify the resistance profile, pathogenicity and efficacy of disinfection of the premises. A total of 91 insects were collected in 21 strategic points of these hospitals, and 32 isolated strains of Staphylococcus aureus were isolated. Based on antibiogram and Minimum Inhibitory Concentration results, 95% of these strains were susceptible to oxacillin. These strains were also evaluated for the presence of resistance genes encoding resistance to oxacillin/methicillin by polymerase chain reaction, but the sample was negative for this gene. Pathogenicity tests were performed in vitro biofilm formation induced by glucose, where it was found that eight (27.58%) strains were classified as biofilm producers and 21 (72.4%) as stronger producers. In addition, we performed PCR for their virulence genes: Sea (enterotoxin A), SEB (B), Sec (C), PVL (Panton-Valentine Leukocidin), ClfA (clumping factor A) and Spa (protein A). Of these, Sea, Spa PVL were positive in 7 (21.8%), 2 (6.3%) and 1 (3.1%) samples, respectively. The analysis of cytokine induction in the inflammatory response of J774 macrophages by isolates from the two hospitals did not show statistical difference at the levels of IL-6, TNF-α, IL-1 and IL-10 production. In addition, we verified the antimicrobial activity of disinfecting agents on these strains, quaternary ammonium, 0.5% sodium hypochlorite, 1% sodium hypochlorite, 2% sodium hypochlorite, 2% glutaraldehyde, Lysoform(®), 70% alcohol solution of chlorhexidine digluconate, 2% peracetic acid, and 100% vinegar.

A investigação foi feita com base em entrevistas realizadas com 195 pessoas, entre elas trabalhadores, empresários, sindicalistas, agentes de fiscalização da frota de ônibus e policiais. Nos últimos dez anos, numa frota de 2.400 ônibus, operada por 10.151 rodoviários, ocorreram 20.572 assaltos, com morte de 67 pessoas e prejuízo computado de mais de um milhão de reais somente para as empresas. O perfil social típico dos agressores é de jovens pobres e desempregados, muitos sem antecedentes policiais, que buscam dinheiro rápido para atividades de lazer, principalmente. Analisou-se o assalto como um encontro perigoso que, além de lesões fatais e não fatais, produz medo, conflitos de identidade, tensões com os passageiros e conflitos trabalhistas referentes ao pagamento dos prejuízos. Foi avaliada também a eficiência das medidas de segurança policial, incluindo o emprego da força letal, mostrando-se a necessidade de medidas mais amplas, de curto, médio e longo prazo, para controlar a violência nos ambientes de trabalho.This paper examines the impact of violent crime on working conditions, health, and security for bus drivers and ticket takers in the mass transportation system in Salvador, Bahia, Brazil.

No Brasil, estudos sobre o uso de anabolizantes são escassos. No presente trabalho, examina-se a percepção de risco à saúde, associada ao consumo de anabolizantes, entre jovens fisiculturistas de um bairro pobre da cidade de Salvador. A metodologia privilegiou métodos de coleta de dados qualitativos tais como etnografia, entrevistas semi-estruturadas e grupo focal com usuários de anabolizantes. Os dados produzidos descrevem as principais substâncias utilizadas e os padrões de uso, e apontam a falta de informação dos jovens entrevistados sobre a extensão dos danos à saúde decorrentes do consumo de anabolizantes, mostrando que para muitos, o desejo de desenvolver massa muscular e alcançar o corpo ideal se sobrepõe ao risco de efeitos colaterais. Os resultados indicam a necessidade de se desenvolver ações culturalmente apropriadas, voltadas para a prevenção do abuso de anabolizantes junto à essa população.Recent studies in different countries have shown an increase in anabolic steroid consumption among young people and the harm caused by indiscriminate use.

Mercúrio foi o principal contaminante encontrado nas ostras e o elemento que apresenta maior risco à saúde pública. Foram encontrados valores de concentração de Hg em ostras de até 551,12µg/kg (peso úmido. Esses valores sugerem que a ingestão de ostras deve ser feita com restrições, principalmente, pela população que vive de sua coleta como forma de subsistência, por crianças, e mulheres grávidas. A avaliação dos níveis de mercúrio em frutos do mar é um importante fator para avaliar o risco de contaminação por mercúrio em pessoas não ocupacionalmente expostas.Samples of oysters marketed in Recife, Pernambuco, Brazil, were monitored for the concentration of trace elements (Hg, Zn, Fe, Cu, and Mn for one year (from March 2001 to February 2002. Mercury was the principal contaminant found in oysters and the element posing the greatest public health risk. Mercury levels in oysters reached 551.12µg/kg (wet weight. These values suggest that oyster consumption should be restricted, especially among communities that gather them as a subsistence activity, as well as by children and pregnant women. Evaluation of mercury concentration in seafood is an important factor for assessing the risk of contamination among individuals who are not occupationally exposed.

In a previous paper, we demonstrated that Mulungu do Morro municipality, in the State of Bahia, has a high seroprevalence to cysticercosis in epileptic patients. OBJECTIVE: to determine the prevalence of taeniasis and positive cysticercosis serology in the population of Mulungu do Morro. METHOD: blood and stool samples were collected from a random sampling of the population, by family. The identification of antibodies against T. solium cysticerci was made by EITB and T. solium antigens were identified using a polyclonal antibody-capture ELISA. RESULTS: the cysticercosis seroprevalence was 1.6% (C.I. = 0.8 to 2.8% and the taeniasis prevalence 4.5% (C.I. = 3.0 to 6.5%. Seropositivity to cysticercosis was higher among those who lived in a house of a person testing positive for coproantigen, p=0.017. CONCLUSION: our results demonstrate that the taeniasis-cysticercosis complex is endemic in Mulungu do Morro. We believe that all areas in the world with the same socio-economic and sanitary characteristics are likely to have high prevalence of this parasite.Embora alguns autores não a considerem uma região endêmica, existem no Nordeste do Brasil as condições necessárias para o desenvolvimento do complexo teníase/ cisticercose.

A atividade central, o trabalho da roça, subordinado às condições precárias de vida permite a produção e reprodução de formas de conceber a vida, e em particular, define os vários conceitos e classificações sobre as necessidades de alimentar o corpo. Em algumas áreas do município de Cansanção, observa-se um modo de conceber o alimento a partir de uma razão subordinada a valores do comércio, mas o fenômeno da seca constitui ainda o determinante da cultura alimentar da população e de suas ações concretas para solucionar a carência alimentar no grupo familiar.This study was developed within the context of the project Cansanção - PROCAN- developed by the Federal University of Bahia, Brazil. The study analyzed information concerning cultural patterns which surround the eating habits of the social groups which live in the semi-arid region of Bahia. It is an ethnographic study carried out over the period of 1987 to 1990. The subject of the investigation was the cultural aspect of eating habits of

    The samples of Tagelus plebeius and Iphigenia brasiliana were manually collected on the Cachoeira River estuary region (Ilhéus, BA, Brazil) between August 2005 and August 2006, with a periodicity of 15 days, with 20 animals collected/sampled, performing 500 samples from each species. The animals were measured, eviscerated and kept in solution of Davidson and after 24-30 hours, they were transferred to ethanol 70%. The material was processed for routine histology, with paraffin embedding, obtaining 7 microm thick slices, stained with Harris hematoxilin and Eosin (HE). By light microscopy analysis, 2 cases of hermaphroditism (0.4%) in T. plebeius samples and one case (0.2%) in I. brasiliana were registered with predominance of female over male follicles.

    Full Text Available A total of 214 stomachs of Clarias gariepinus, Centropomus undecimalis and C. parallelus from the Itanhém and Caravelas Rivers, northeastern Brazil, were analyzed to investigate the impact of the non-native species Clarias gariepinus on the Itanhém River food web as compared to that of the adjacent Caravelas River, where this species has not been registered. In Itanhém River, shrimp was the most important food for C. gariepinus, and Teleostei for C. parallelus. In the Caravelas River, Brachyura was the main food item for C. parallelus, and Teleostei for C. undecimalis. There was no food overlap between the species within or between rivers. There is no evidence, in the results of this study, of changes in the diet of the Centropomus parallelus due to the presence of the non-native species.

    Full Text Available Temporary wetlands undergo recurrent drought due to the scarcity of water, which disrupts the hydrological connectivity with adjacent aquatic systems. However, some environments retain water for longer periods, allowing greater persistence of the community. The current study evaluated differences in the microcrustacean assemblages and limnological variability between perennial and intermittent pools in a semi-arid region of Brazil. The abiotic features (water temperature, pH, total alkalinity, electrical conductivity and depth of intermittent pools were affected more than perennial pools due to loss of water volume. This may have contributed to a higher average richness and diversity index in some intermittent pools and differences in the structure of the assemblages. The lowest species richness and diversity were recorded where physical factors, such as a large quantity of suspended solids and variability in the electrical conductivity of the water and pH, make the environment unsuitable for these organisms. These results suggest that community development in intermittent pools is interrupted by the dry season; when the water returns, due to rainfall or rising groundwater, each pond undergoes a different process of colonization. In these circumstances, the biological importance of temporary aquatic environments is clear, since such pools provide shelters and have an important role in the maintenance of the regional diversity of aquatic environments.

    Full Text Available In this work, we investigate the feeding habits of Pleurodema diplolistris, the most abundant anuran species of the São Francisco sand dunes, during a period of slightly over one year. The fieldwork was undertaken during four excursions to a sand dune in the semiarid Caatinga, Brazil, and the analyses were based on stomach contents. Pleurodema diplolistris were not active during the dry season. The important food categories in diet were Isoptera (winged forms, Coleoptera, and Formicidae. Small and large animals had different food comsumption patterns: small frogs showed positive electivity for termites and large frogs, for ants. The pattern was strongly influenced by large male food electivity. High levels of termite comsumption ocurred during the days of greater capture success. The pattern of high comsumption of termites detected here is different from that described in another study on lizards from the same locality and sampled in the same periods. We discuss alternative hypotheses that could explain the observed patterns.

    In Brazil, sexual violence against children and adolescents is a challenge for the public policies of prevention and intervention. The objective of this article is to present the evaluation of PAIR actions implemented in Feira de Santana city, on political and institutional integration, strength and performance of the Network Care for the violence victims in the period of 2003-2006. It was used a descriptive study with primary data based on interviews with professionals from the Institutions of care (38), Municipal Committee of PAIR (11) and key community informants (78), using quantitative and qualitative analysis. The evaluation of the PAIR capabilities, as the political and institutional integration was deemed appropriate, highlighting the support of state, federal and municipal managers. The processes of training were considered strategic to the individual professional performance with the Network (attitudes, participation). The results of the three segments of the community suggest the need of a social Network integration (Rights and Guardianship Councils), programs of assistance and protection, the work with the media (qualified training and information), involvement of managers and technicians and the continuity of actions, as strategies to face the sexual violence in Feira de Santana.

    The impact of human activity on the sediments of Todos os Santos Bay in Brazil was evaluated by elemental analysis and 13C Nuclear Magnetic Resonance (13C NMR). This article reports a study of six sediment cores collected at different depths and regions of Todos os Santos Bay. The elemental profiles of cores collected on the eastern side of Frades Island suggest an abrupt change in the sedimentation regime. Autoregressive Integrated Moving Average (ARIMA) analysis corroborates this result. The range of depths of the cores corresponds to about 50 years ago, coinciding with the implantation of major onshore industrial projects in the region. Principal Component Analysis of the 13C NMR spectra clearly differentiates sediment samples closer to the Subaé estuary, which have high contents of terrestrial organic matter, from those closer to a local oil refinery. The results presented in this article illustrate several important aspects of environmental impact of human activity on this bay. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The uranium mining at Caetité (Uranium Concentrate Unit—URA) is in its operational phase. Aiming to estimate the radiological environmental impact of the URA, a monitoring program is underway. In order to preserve the biota of the deleterious effects from radiation and to act in a pro-active way as expected from a licensing body, the present work aims to use an environmental protection methodology based on the calculation of absorbed dose rate in biota. Thus, selected target organism was the Tilapia fish (Tilapia nilotica, Linnaeus, 1758) and the radionuclides were: uranium (U-238), thorium (Th-232), radium (Ra-226 and Ra-228) and lead (Pb-210). As, in Brazil there are no radiation exposure limits adopted for biota the value proposed by the Department of Energy (DOE) of the United States of 3.5×103 μGy y-1 has been used. The derived absorbed dose rate calculated for Tilapia was 2.51×100 μGy y-1, that is less than 0.1% of the dose limit established by DOE. The critical radionuclide was Ra-226, with 56% of the absorbed dose rate, followed by U-238 with 34% and Th-232 with 9%. This value of 0.1% of the limit allows to state that, in the operational conditions analyzed, natural radionuclides do not represent a radiological problem to biota.

    The spatial and temporal distribution of organisms is a fundamental aspect of biological communities. The present study focused on three remnants of arboreal Caatinga in northeastern Brazil between May, 2009 and April, 2010. A total of 627 euglossine males were captured in traps baited with artificial aromatic compounds. The specimens belonged to 14 species and four genera: Euglossa Latreille, Eulaema Lepeletier, Eufriesea Cockerell, and Exaerete Hoffmannsegg. Eulaema nigrita Lepeletier (41.6), Euglossa carolina Nemésio (15.3%), Eulaema marcii Nemésio (13.6%), and Euglossa melanotricha Moure (12.8%) were the most common species sampled. The distribution of collected specimens per fragment was as follows: Braúna (280 ha)--259 individuals belonging to 14 species; Cambuí (179 ha)--161 individuals from eight species; and Pindoba (100 ha)--207 individuals represented by seven species. Braúna had the highest diversity (H' = 1.91) and estimated species richness. The largest fragment was the main source of the observed variation in species richness and abundance, indicating a non-random pattern of spatial distribution. The analysis of environmental factors indicated that seasonal variation in these factors was the principal determinant of species occurrence and abundance.

    Full Text Available Foi realizado um estudo com o objetivo de descrever certos aspectos epidemiológicos dos acidentes de trânsito de veículo a motor, na cidade do Salvador, Bahia, Brasil, o qual envolveu coleta de informações no Departamento de Trânsito (DETRAN e no Instituto de Medicina Legal. Ficou demonstrado que os acidentes de trânsito de veículo a motor são mais freqüentes ao fim da tarde e concentram-se, sobretudo, no fim de semana, isto é, sábado e domingo. Motoristas do sexo masculino foram muito mais freqüentemente envolvidos em acidentes de trânsito do que os do sexo feminino. Foi concluído que os acidentes fatais envolvendo pedestres constituem-se importante problema urbano necessitando cuidadosa atenção por parte de educadores e dos serviços públicos responsáveis pelo setor do trânsito. Foi sugerida a necessidade de melhorar e tornar mais uniforme o sistema de notificação e classificação dos acidentes de veículo a motor pelo DETRAN da cidade do Salvador.A study was made aiming at the description of epidemiologic aspects of fatal motor vehicle accidents in the City of Salvador, Brazil. The study involved the collecting of data in both the Traffic Department (DETRAN and the Legal Medicine Institute. The study showed a time relationship, i.e., the highest percentage of accidents due to motor vehicles was concentrated at noon and during weekends. Young male drivers were more frequently involved in accidents than females of the same age. The authors indicated that pedestrian fatal accidents are essencially an urban problem needing a great deal of concern by educators and providers of public services. They also suggested the necessity of improving and of homogenizing the notification and classification system of motor vehicle accidents by the DETRAN in Salvador.

    Eucalyptus plantations are increasing in Brazil,frequently replacing pastures,but there is still scarce information about its capacity to maintain the fauna of neighbor forest remnants.In this study,we compared descriptors of the communities of leaf litter organisms (lizards,anurans,myriapods,arachnids,orthopterans,coleopterans,and ants)between a large remnant of primary Atlantic Forest and an adjacent eucalyptus monoculture (phase 1).Then,we compared the same descriptors for leaf litter lizards and anurans,Euglossini bees,and frugivorous butterflies among the largest remnant,small remnants at intermediate regeneration stage,and eucalyptus monocultures that were not adjacent to the largest remnant (phase 2).Monocultures were sampled immediately before logging.In phase 1,we detected significant differences in structure between the forest and the monoculture in six out of seven communities sampled.Ca.81% of the species of the landscape were recorded in the forest,but only 54% of these were found also in the monoculture.In phase 2,the structure of two out of four forest communities was significantly different from the structure of small remnants and monocultures.On average,76% of the species found in the whole landscape were sampled in the forest.Out of this subset,on average 74% of the species were also sampled in small remnants and 68% in monocultures.Findings of the present study point out a moderate capacity of eucalyptus monocultures to harbor species of the forest fauna even when fully grown but highlights the opportunity that they might offer for increasing connectivity in anthropogenic forest landscapes depending on their management.

    This is a color composite image of southern Bahia, Brazil, centered at 15.22 degree south latitude and 39.07 degrees west longitude. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar aboard the space shuttle Endeavour on its 38th orbit of Earth on October 2, 1994. The image covers an area centered over the Una Biological Reserve, one the largest protected areas in northeastern Brazil. The 7,000-hectare reserve is administered by the Brazilian Institute for the Environment and is part of the larger Atlantic coastal forest, a narrow band of rain forest extending along the eastern coast of Brazil. The Atlantic coastal forest of southern Bahia is one of the world's most threatened and diverse ecosystems. Due to widespread settlement, only 2 to 5 percent of the original forest cover remains. Yet the region still contains an astounding variety of plants and animals, including a large number of endemic species. More than half of the region's tree species and 80 percent of its animal species are indigenous and found nowhere else on Earth. The Una Reserve is also the only federally protected habitat for the golden-headed lion tamarin, the yellow-breasted capuchin monkey and many other endangered species. In the past few years, scientists from Brazilian and international conservation organizations have coordinated efforts to study the biological diversity of this region and to develop practical and economically viable options for preserving the remaining primary forests in so
