| an outbreak of acute chagas's disease in the são francisco valley region of bahia, brazil: triatomine vectors and animal reservoirs of trypanosoma cruzi. | following reports of an unusually high incidence of acute chagas's disease and the appearance of large numbers of triatoma infestans in the southwestern region of the state of bahia, triatomine bugs (hemiptera: reduviidae) and domestic animals in one of the affected communities were surveyed and examined for infection with trypanosoma cruzi. triatoma infestans was prevalent in houses and was also found in peridomestic habitats. t. sordida and t. pseudomaculata occupied peridomestic and sylvatic ... | 1979 | 120045 |

| [occurrence of platynosomum illiciens in enclosured wild cats in the state of bahia, brazil]. | this paper reports the occurrence of eggs of platynosomum illiciens, found in the feces of three species of wild cats herpailurus yagouaroundi, puma concolor and leopardus tigrinus from material collected at the enclosures of the park zoobotânico getúlio vargas in salvador, bahia, brazil. it is the first record of this parasite in p. onca and l. tigrinus. | 2008 | 19265585 |
| toxoplasma gondii and neospora caninum in sparrows (passer domesticus) in the northeast of brazil. | toxoplasma gondii is a cosmopolitan protozoan parasite of warm-blooded animals that causes high rates of infection in mammals and birds. sparrows (passer domesticus) are synantropic birds which are distributed worldwide. they serve as intermediate hosts for the parasite but are quite resistant to toxoplasmosis. the aims of this study were to determine the frequency of t. gondii infection in sparrows using serologic and molecular tests, and to investigate related parasites, such as neospora canin ... | 2010 | 19879051 |
| frequency of antibodies against sarcocystis neurona and neospora caninum in domestic cats in the state of bahia, brazil. | 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 par ... | 2017 | 25517534 |
| epidemiological aspects of three trypanosoma cruzi zymodemes in bahia state, brazil. | culture forms of 104 stocks of trypanosoma cruzi isolated in different regions of the state of bahia were compared by electrophoresis of six enzymes. the three distinct combinations of isoenzyme patterns seen were designated zi, z2 and z3. in an area of endemic chagas's disease in eastern bahia, t. cruzi z1 was associated with sylvatic mammals and sylvatic triatomines, whereas t. cruzi z2 was associated with a separate domestic cycleof transmission. t. cruzi z1 was also found in sylvatic triatom ... | 1980 | 6776664 |
| comparison of two coproparasitological techniques for the detection of platynosomum sp. infection in cats. | platynosomum sp. is the etiologic agent of platynosomiasis, a hepatic disease that affects domestic cats. the parasite develops in the bile ducts and gallbladder, causing severe hepato-biliary disease. considering the importance of the disease and the increase in the number of households with cats, the aim of this study was to compare two different techniques for the detection of the parasite's eggs and to assess the frequency of platynosomum sp. infection in cats. forty fecal samples from cats ... | 2014 | 24877787 |
| [prevalence and risk factors of human infection by toxocara canis in salvador, state of bahia, brazil]. | larva migrans visceral is caused by toxocara sp and has never been studied in bahia. this work investigated the prevalence and risk factors for infection by toxocara canis in individuals from salvador, state of bahia. | 2011 | 21860903 |
| oocysts ingestion as an important transmission route of toxoplasma gondii in brazilian urban children. | abstract toxoplasmosis is a cosmopolitan protozoan infection. data regarding risk factors for the post-natal acquisition of toxoplasma gondii infection in childhood are limited. we conducted a serological survey for t. gondii igg antibodies and associated risk factors in 1,217, 4- to 11-yr-old children from salvador, brazil using a commercial elisa kit; antibodies were found in 17.5% of the children. age (or=2.18; 95%ci: 1.50-3.17) and maternal schooling level (or=0.62; 95%ci: 0.42-0.92) were ne ... | 2011 | 21740247 |
