| study on chagas disease occurrence in the municipality of monte negro, state of rondônia, brazilian amazon. | studies on chagas disease deal with the perspective of its occurrence in the amazon region, which is directly correlated to the population growth and the spread of the bug biotope. the state of rondônia has an immense source of vectors (triatomine) and reservoirs of trypanosoma cruzi. environmental changes brought forth by the deforestation in the region may cause vector behavior changes and bring these vectors to a closer contact with humans, increasing the probability of vector infection. | 2011 | 22231244 |
| First report of Eratyrus mucronatus, Stal, 1859, (Hemiptera, Reduviidae, Triatominae), in the State of Rondônia, Brazil. | This paper reports, for the first time, the presence of the Eratyrus mucronatus species in the State of Rondonia, Brazil. | 2011 | 21860901 |
| tesa-blot for the diagnosis of chagas disease in dogs from co-endemic regions for trypanosoma cruzi, trypanosoma evansi and leishmania chagasi. | we standardized serodiagnosis of dogs infected with trypanosoma cruzi using tesa (trypomastigote excreted-secreted antigen)-blot developed for human chagas disease. tesa-blot showed 100% sensitivity and specificity. in contrast, elisa using tesa (tesa-elisa) or epimastigotes (epi-elisa) as antigen yielded 100% sensitivity but specificity of 94.1% and 49.4%, respectively. when used in field studies in an endemic region for chagas disease, visceral leishmaniasis and trypanosoma evansi (mato grosso ... | 2009 | 19426657 |
| chagas' disease in the amazon basin: v. periurban palms as habitats of rhodnius robustus and rhodnius pictipes--triatomine vectors of chagas' disease. | trypanosoma cruzi infected rhodnius robustus and/or rhodnius pictipes were commonly found, in large numbers, in the brazilian amazonian palms maximiliana regia ("inajá"), acrocomia sclerocarpa ("mucajá") and orbignya speciosa ("babaçu"). the common opossum, didelphis marsupialis, was the animal most frequently associated with triatomine infested palms. r. pictipes, frequently light-attracted into houses from palm trees, was the probable source of an acute case of chagas' disease in the vicinity ... | 1983 | 6443629 |
| chagas' disease in the amazon basin iv. host records of trypanosoma cruzi zymodemes in the states of amazonas and rondonia, brazil. | of 151 trypanosoma cruzi stocks from 117 different individual hosts collected in the states of amazonas and rondonia, 147 from 113 hosts were identified as zymodeme 1 (z1). these included t. cruzi stocks from three marsupial species, two rodent species and three triatomine species although most were from the common opossum, didelphis marsupialis. one t. cruzi stock from rhodnius robustus was identified as z1 with a z3 pgm character, one from sciurus sp. as z3 and two from monodelphis brevicaudat ... | 1984 | 6441530 |
| vertebrate hosts and vectors of trypanosoma rangeli in the amazon basin of brazil. | a total of 46 trypanosoma rangeli stocks were isolated from naturally infected mammals and triatomine vectors. twenty-two stocks were from the common opossum (didelphis marsupialis), one from the brown "4-eyed" opossum (metachirus nudicaudatus), one from the anteater (tamandua tetradactyla), one from the coati (nasua nasua), seven from rhodnius pictipes and 14 from rhodnius robustus. two stocks were also isolated from recently fed sandflies (lutzomyia sp., shannoni group). the stocks were identi ... | 1983 | 6418015 |
