Resumo: | During observations on a foros of enzootic leishmaniasis of rodents in the Utinga Forest, Belém, Pará, Brazil, active infections were encountered in 16 (17.98%) of 89 Oryzomys capito examined. Cutaneous lesions were restricted to the tails of these animaIs, and spontaneous recovery leaves characteristic scarring. Taking such scars into account, it is estimated thb.t as manyas 70% ofthe Oryzomys population mar experience infection at some time during their lives. Leishmania were isolated from 3 specimens of Proechimys guyannensis captured in the same forest area. ln addition to obvious lesions on the tail and foot, parasites were isolated from apparently normal ear tissue. The strains of Leishmania from Oryzomys and Proechimys appear to be identical. lnsect traps were baited with Oryzomys, Proechimys and other rodents. During a period of 4 months they, captured 2- ~7 4 phlebotomine sandflies, of which 2,731 were Lutzomyia ftaviscutellata[ Mangabeircy ln contrast, on1y 5 specimens (0.690;0) of Lu. ftaviscutellata were encountered among 724 sandflies caught of human bait during the same period, in the same area. Leptomonads were found in 8 of 2,706 Lu. ftaviscutellata dissected (0.29%). lnoculation of these flagellates into hamsters produced typical leishmanial lesions in 6 cases. We conclude that Lutzomyiaftaviscutellata is the major vector ofthe Leishmania sp., among Oryzomys and Proechimys in the Utinga Forest area ofthe Lower Amazon Region. Similarities are noted between this parasite of Brazilian rodents and Leishmania mexicana of rodents and man in Central America. |
