| [natural hosts of trypanosoma cruzi in french guiana. high endemicity of zymodeme 1 in wild marsupials]. | during an epidemiological survey in french guiana, three species of marsupiala were found infected by trypanosoma cruzi with high infection rates (30,8% for didelphis marsupialis). six triatomine bug species were recorded, five of them being well known vectors of chagas' disease. iso-enzyme characterization of 22 stocks isolated (16 from d. marsupialis, 3 from philander opossum and 3 from rhodnius prolixus) revealed that they were all related to zymodeme 1 of miles. the silvatic cycle is endemic ... | 1985 | 3923891 |

| genetic exchange as a possible source of genomic diversity in sylvatic populations of trypanosoma cruzi. | thirty six stocks of trypanosoma cruzi isolated from sylvatic mammals (32 didelphis marsupialis and one philander opossum) and triatomine bugs (rhodnius robustus and one unidentified bug) in the amazonian forest by carajas, brazil were characterized by isoenzyme and random amplified polymorphic dna (rapd) analysis as belonging to principal zymodeme '1 (z1). two different homozygous phenotypes and the corresponding heterozygous phenotype were found for phosphoglucomutase with an observed frequenc ... | 1996 | 8615458 |
| humoral immune response kinetics in philander opossum and didelphis marsupialis infected and immunized by trypanosoma cruzi employing an immunofluorescence antibody test. | philander opossum and didelphis marsupialis considered the most ancient mammals and an evolutionary success, maintain parasitism by trypanosoma cruzi without developing any apparent disease or important tissue lesion. in order to elucidate this well-balanced interaction, we decided to compare the humoral immune response kinetics of the two didelphids naturally and experimentally infected with t. cruzi and immunized by different schedules of parasite antigens, employing an indirect fluorescence a ... | 1999 | 10348985 |
| infection by trypanosomes in marsupials and rodents associated with human dwellings in ecuador. | small mammals trapped in domestic and peridomestic environments of rural ecuador were screened for trypanosome infection by direct microscopy and hemoculture. identification of species of trypanosomes was then performed by morphological characteristics and by polymerase chain reaction (pcr) assays. of 194 animals collected, 15 were positive for infection (7.73%). eight (4.12%) were infected with trypanosoma cruzi (1 of 33 didelphis marsupialis; 7 of 61 rattus rattus). eleven r. rattus (18.03%) h ... | 2006 | 17304802 |
| trypanosoma cruzi among wild and domestic mammals in different areas of the abaetetuba municipality (pará state, brazil), an endemic chagas disease transmission area. | the presence of acute chagas disease (acd) due to oral transmission is growing and expanding in several south american countries. within the amazon basin, the abaetetuba municipality has been a site of recurrent cases spanning across distinct landscapes. because chagas disease is primarily a zoonotic infection, we compared the enzootic trypanosoma cruzi transmission cycles in three different environmental areas of abaetetuba to better understand this new epidemiological situation. philander opos ... | 2013 | 23261089 |
