【 摘 要 】

In order to identify Trypanosoma cruzi reservoirs in transmission areas, 60 mammals in Capital and San Luis del Palmar Departments, Corrientes, Argentina were studied. Primates, rodents, carnivores, marsupials and edentates were investigated, 40 of them living in captivity and 20 caught with traps in a rural area. The mammals were examined by xenodiagnosis and third or fourth instars nymphs of Triatoma infestans starved for 2 weeks were used. The feces were microscopically observed (400x) for Trypanosoma cruzi infection at 30, 60 and 90 days after feeding. Trypanosoma cruzi-like parasites were identified in 2 Saimiri sciureus and 1 Cebus apella analyzed by xenodiagnosis. It was concluded that parasitemia was low. Howewer, the presence in a forest area of Didelphis albiventris, potential reservoir of the parasite, indicates a risk factor and deserves further epidemiological study for a true diagnosis of this endemic infection .
