Capacidade de replicação da cepa y trypanosoma cruzi em diferentes espécies de triatomíneos

Abstract

Capacity of replication of different triatomine species was investigated by applying xenodiagnosis in mice during acute Trypanosoma cruzi infection ("Y" strain). Twenty insect bugs for each one of the studied species were applied on infected mice. Each bug was examined individually. The species capacity of replication in relation with the number of the excreted trypanosomes was ; Dipetalogaster maximus, Panstrongylus herreri, Triatoma rubrovaria, T.íibiamaculata, T.matogrossensis, T. protracta, T. sórdida má Rhodnius prolixas. . , prolixas.

The experirnents were performed at 28 ± 1°C, 70 ± 5% of relative humidity and photoperiod of 12 h.
