| trypanosoma cruzi infection in wild mammals of the national park 'serra da capivara' and its surroundings (piaui, brazil), an area endemic for chagas disease. | we studied the prevalence of trypanosoma cruzi infection among eight species of wild small mammals (n=289) in an area where human cases of infection/disease have occurred. dogs (n=52) and goats (n=56) were also surveyed. the study was carried out inside a biological reserve, the national park 'serra da capivara' and its surroundings in piaui state, brazil. the marsupial didelphis albiventris and the caviomorph rodent trichomys apereoides were found to be the most important reservoirs in the stud ... | 2005 | 15780345 |
| mapping of the distribution of trypanosoma cruzi infection among small wild mammals in a conservation unit and its surroundings (northeast-brazil). | maps are a useful tool that permits correlation of landscapes with hotspots of parasite transmission. here, they were used as a tool for geovisualization to evaluate variables involved in the transmission of trypanosoma cruzi among small wild mammals in an area endemic for chagas disease, the "serra da capivara" national park (parna) and its surroundings in piauí state, northeast brazil. the implementation of a geographical information system (gis) allowed the observation that a previously noted ... | 2007 | 17307027 |
