Studies on trypanosoma rangeli tejera, 1920 x-its comparison with trypanosoma cruzi chagas, 1909. Infection in differents st ages of rhodnius prolixus stal, 1859
The comparison among specimens of Rhodnius prolixus, at different stages of development, exposed to infections by Trypanosoma rangeli and Trypanosoma cruzi, revealed that the bugs exposed to T. cruzi showed a significant higher susceptibility to infection than that observed in the groups exposed to...
