Seven Trypanosoma spp. isolates obtained from bats (Eptesicus sp.) were characterized using experimental infection in mice, triatomines, and culicines; complement lysis; indirect fluorescence assays; as well as isoenzyme and random-amplified polymorphic DNA (RAPD) profiles. The Trypanosoma sp. isolates were compared with Trypanosoma cruzi, Trypanosoma rangeli. and 2 other bat trypanosomes species, Trypanosoma vespertilionis and Trypanosoma hastatus. Trypanosoma sp. isolates were different from the other species in all experiments, except in complement lysis. Experimental infection of triatomines and culicines with Trypanosoma sp. proved to be transitory. These parasites were noninfective for both normal and immunosuppressed mice. Isoenzyme and RAPD profiles obtained for Trypanosoma sp. were quite distinct from T. cruzi and T. rangeli and closely related to T. vespertilionis and T. hastatus. No cross-reaction was observed between sera from mice infected with Trypanosoma sp. and the other trypanosomatids and vice-versa. Trypanosoma sp. induced no protection against T. cruzi infection in mice. The very low, or nonsimilarity between Trypanosoma sp. isolates and the other species used in this study suggests that they might be members of a distinct bat trypanosome species. However, further studies should be done to prove their affinities with Trypanosoma cruzi-marinkellei, another trypanosome species from bats.
