Estudo sobre triatomíneos e reservatórios silvestres de Trypanosoma cruzi no estado do Paraná, Sul do Brasil. Resultados preliminares

Abstract: Em localidades da zona rural de cinco municípios da região noroeste do Paraná adultos e ninfas de Triatoma sordida foram capturados em 21 (41,2%) de 51 unidades domiciliares pesquisadas. Foram capturados 154 exemplares de T. sordida e 2 Panstrongylus megistus. De 135 exemplares examinados 58 (43,0%) apresentavam o Trypanosoma tipo cruzi. Constatou-se também a infecção em 57,1% (4/7) dos gambás (Didelphis sp) examinados. O peridomicílio apresentou-se mais infestado que o intradomicílio, sendo a casa de madeira … Show more

“…The ability of T. sordida to colonize both natural and artificial ecotopes, along with its high tolerance to environmental change 15 , makes it an important vector in the parasite cycle and difficult to control. Despite T. sordida being considered a species that prefers to infect birds, the high rates of peridomestic infestation (20%) and parasitic infection (18%) suggest that surveillance is necessary because the mere coexistence with a vector increases the possibility of human infection 16 besides presenting a higher rate of infection when compared with other surveys 8,17,18 . Other studies showed that T. sordida is the most frequent in captures 17 -also peridomestic and domiciliary infestation reaching 86.6% 8 and 47.7%…”

“…Of these, T. sordida and P. megistus are the predominant species found in north/northwest Parana (Toledo et al 1997, Guilherme et al 2001. In southern Brazil, P. megistus is present in wooded ecotopes, only sporadically invades houses, and very rarely establishes colonies in a domicile.…”

“…Triatoma sordida Stål, 1859 destaca-se, atualmente, como a espécie de triatomíneo mais capturada no Brasil, predominantemente, em ambiente peridomiciliar, sendo potencial vetor de Trypanosoma cruzi, agente etiológico da doença de Chagas (DC) [1][2][3] . Nesse ambiente, pode ser encontrado habitando ecótopos, tais como: montes de madeira e de telhas, cercas de madeira, galinheiros e chiqueiros 4,5 .…”
