Sexual transmission of American Trypanosomes from males and females to naive mates
Almeida, Adriana B.; Araújo, Perla F.; Bernal, Francisco Ernesto Moreno; Rosa, Ana de Cassia; Valente, Sebastião A.American trypanosomiasis is transmitted to humans by triatomine bugs through the ingestion of contaminated food, by blood transfusions or accidently in hospitals and research laboratories. In addition, the Trypanosoma cruzi infection is transmitted congenitally from a chagasic mother to her offspring, but the male partner's contribution to in utero contamination is unknown. The findings of nests and clumps of a...
Sexual transmission of American trypanosomiasis in humans : a new potential pan...

We hypothesised that the sexual transmission of T. cruzi contributes to the ongoing spread of Chagas disease. Objectives: a short-term longitudinal study was conducted to evaluate this hypothesis. Methods: the study population com...
