| Abstract | A study was conducted to determine the prevalence of natural infections by trypanosome species in
squirrel monkeys: Saimiri sciureus (Linnaeus) and Saimiri ustus (Geoffroy) caught respectively near 2
hydroelectric plants: Balbina, in the State of Amazonas, and Samuel, in the State of Rondônia, Brazil. A
total of 165 squirrel monkeys were examined by thick and thin blood smears (BS), haemocultures and
xenodiagnosis: 112 monkeys, 67.9%,(being 52.7% with mix infections) were positive to trypanosomes.
Four species of trypanosomes were found in monkeys from the 2 areas: Trypanosoma (Tejeraia) rangeli
Tejera or T. rangeli-like parasites in 58 squirrel monkeys (35.2%), Trypanosoma (Megatrypanum)
minasense Chagas in 55 (33.3%), Trypanosoma (Herpetosoma) saimirii Rodhain or T. saimirii-like
parasites in 53 (32.1%) and Trypanosoma (Schizotrypanum) cruzi Chagas in 17 (10.3%). As T. saimirii
resembles T. minasense in blood-stream trypomastigotes and T. rangeli in cultural forms and in this
survey almost all monkeys presenting trypanosomes morphologically indistinguishable from T. saimirii
and/or T. minasense in BS were found through xenodiagnosis and/or haemoculture to be infected by T.
rangeli, we suggest that the validity of T. saimirii needs to be evaluated. | pt_BR |
