Abstract
This chapter describes results of experiments conducted to study host–parasite relationships in Rangeli trypanosomiasis. Over a thousand nymphs of Rhodnius protixus and Triatoma infestans infected by artificial xenodiagnosis with either a Venezuelan or a Costa Rican strain of Trypanosoma rangeli revealed a higher percentage of intestinal infection in R. prolixus for the former strain, as shown by the examination of feces. The examination of the hemolymph revealed that almost one-third of the R. prolixus became permanently infected with the Venezuelan strain, whereas some of the T. infestans had only a transient infection. There was no correlation between results from the feces and those given by the hemolymph. The Costa Rican strain was less able to infect the hemolymph of R. prolixus and could not infect that of T. infestans.
