Abstract

From April 1984 to March 1985, a Trypanosoma lewisi check for this species in other resources prevalence of 21.7% was found in 429 Rattus norvegicus check for this species in other resources trapped in Belo Horizonte, State of Minas Gerais, Brazil. The infection rates were higher in male and young rats and could be attributed to ecological and behavioral factors. T. lewisi was observed in rats measuring between 60 and 250 mm. Data about monthly T. lewisi infections throughout the year are presented for the first time in Brazil, with the highest prevalences observed in the warm-rainy season (October to March).
