Morphobiological, morphometric and ultrastructural characterization of sylvatic trypanosoma cruzi isolates from Rio de Janeiro State, Brazil
Triatoma vitticeps is a triatomine with geographic distribution restrict to Brazil, which exhibits high prevalence of Trypanosoma cruzi natural infection. Of special epidemiologic concern, this species often invades households in the states of Rio de Janeiro, Minas Gerais and Espírito Santo. The obj...
