Abstract

The parasite-vector interaction of Chagas disease is still poorly understood and the understanding of this relationship can help in the development of new strategies to controlTrypanosoma cruzitransmission, which is the etiological agent of this disease. Considering the need to know ifT. cruzican cause some pathology in the reproductive system of the Chagas disease vectors, we investigated the spermatogenesis ofTriatoma infestansinfected byT. cruzithrough histological and cytogenetic analysis.Trypanosoma cruziBolivia strain infection was not pathogenic for the reproductive system ofT. infestans, because all the analyzed males had normal spermatogenesis, with all phases (spermatocytogenesis, meiosis and spermiogenesis) happening without any change. Thus, we demonstrated that the presence ofT. cruziBolivia strain does not have influence in the spermatogenesis ofT. infestansand we suggest that the influences on reproductive system observed for other species were a result of the action of the parasite on gametogenesis of females.
