| chickens (gallus domesticus) are natural intermediate hosts of neospora caninum. | neospora caninum naturally infects many mammal species, but has not previously been demonstrated in birds. we examined sera for n. caninum antibodies from 200 outdoor chickens and from 200 chickens confined indoors in the state of bahia, brazil. seroprevalence was greater in outdoor chickens (23.5% versus 1.5%, p<0.001). pcr testing for n. caninum was positive in six of 10 seropositive chickens. amplicons from two of these were sequenced and had 97-98% nucleotide identity with n. caninum. this f ... | 2008 | 18054356 |
| impact of environment and social gradient on leptospira infection in urban slums. | leptospirosis has become an urban health problem as slum settlements have expanded worldwide. efforts to identify interventions for urban leptospirosis have been hampered by the lack of population-based information on leptospira transmission determinants. the aim of the study was to estimate the prevalence of leptospira infection and identify risk factors for infection in the urban slum setting. | 2008 | 18431445 |
| molecular frequency and isolation of cyst-forming coccidia from free ranging chickens in bahia state, brazil. | the toxoplasmatinae parasites toxoplasma gondii, neospora caninum and hammondia spp. have carnivores as definitive hosts that shed the parasite oocysts in their feces. birds that feed directly from the soil, such as chickens, are exposed to infection and may serve as indicators of the presence of the parasite in the environment and as a source of infection for other animals. the aims of this study were to determine the frequency of infection by these parasites in free ranging chickens, to test w ... | 2012 | 22673105 |
| [preliminary results of a project about the ecology of phlebotomus vectors of cutaneous leishmaniasis in the state of bahia]. | preliminary data of a project about the ecology of the phlebotominae (sandflies) in a tegumentary leishmaniasis area of coconut plantation in the south of the state of bahia, brazil are presented. there are 60 dwellings far of one another, where existed 31 dogs and 229 inhabitants. among them 41.5% were montenegro positive; 37.5% from these had scars of healed ulcers and 8.8% had active ulcers. 53% of the house had dogs from which 22% were seropositive; from the 7 dogs with ulcers only 3 were se ... | 1996 | 8713612 |
| genetic diversity of toxoplasma gondii isolates from chickens from brazil. | until recently, toxoplasma gondii was considered clonal with very little genetic variability. recent studies indicate that t. gondii isolates from brazil are genetically and biologically different from t. gondii isolates from usa and europe. in the present study, we retyped 151 free range chicken isolates from brazil including 117 newly isolated samples from 11 geographically areas (alagoas, bahia, ceará, maranhão, paraná, pernambuco, rio de janeiro, rio grande do norte, são paulo, sergipe, and ... | 2008 | 18804329 |
| toxoplasma gondii isolates from free-range chickens from the northeast region of brazil. | the prevalence of toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of t. gondii oocysts in the soil because chickens feed from the ground. the prevalence of t. gondii in 152 free-range chickens (gallus domesticus) from 22 municipalities in 7 northeastern states (pernambuco, rio grande do norte, maranhão, bahia, ceará, sergipe, and alagoas) of brazil was determined. antibodies to t. gondii were assayed by the modified agglutination test (mat); 81 (53.3 %) chickens ... | 2009 | 18578589 |
| agriculture and snakebite in bahia, brazil - an ecological study. | this study investigated the correlation between the incidence of snakebite and indicators of agricultural development in municipal districts of the state of bahia, brazil. an ecological study was conducted with the 27,347 cases of snakebite poisoning reported to the reportable diseases national information system in municipalities from the state of bahia, brazil, 2000-2009. the unit of analysis was each one of the 417 state municipalities, and the outcome variable was the average annual incidenc ... | 2016 | 27660860 |
| methicillin-resistant staphylococcus aureus in raw meats and prepared foods in public hospitals in salvador, bahia, brazil. | this study investigated the presence of methicillin-resistant staphylococcus aureus (mrsa) in raw meat and fish and foods prepared from them for patient consumption in public hospitals in salvador, bahia, in northeastern brazil. a total of 114 samples of raw meat and fish (chicken, n = 30; beef, n = 30; pork, n = 24; and fish, n = 30) and 63 samples of prepared foods (made with chicken, n = 15; beef, n = 15; pork, n = 15; and fish, n = 18) were collected from the kitchens of 10 different hospita ... | 2015 | 25472504 |
| [overweight and abdominal obesity in adults in aquilombocommunity in bahia state, brazil]. | 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 o ... | 2014 | 24627062 |
