Resumo: | OBJECTIVE: T. pseudomaculata, a peridomicilar species, has low rates of T. cruzi infection. The occurrence of this triatomine in the domicile and its feeding patterns was investigated to identify potential T. cruzi reservoirs. METHODS: Nine-hundred and twenty-one specimens of T. pseudomaculata were captured from January 2001 to July 2002 in 13 southern municipalities of the state of Ceará, Brazil. The intestinal contents of the triatomines was removed, spread in a filter paper and tested for the following antisera: bird, cat, cockroach, dog, human, lizard, opossum, ox/goat, pig, and rodent. The presence of T. cruzi was investigated by wet mount microscopic exam and culture (NNN+LIT) of intestinal contents. RESULTS: Of the total studied, 184 (90.6%) were positive for the tested antisera: bird (62.5%)>; rodent (33.7%)>; dog (20.1%)>; opossum (9.8%)>; lizard and ox/goat (5%)>; cat (2.7%)>; pig and cockroach (2.2%)>; human (1.6%). Blood meals ranged from none (non-reactive) to four as follows: non-reactive (9.4%), one (57.1%), two (26%), three (7%), and four (0.5%). Only three specimens (1.6%) had T. cruzi infection. CONCLUSIONS: The low incidence of human blood meal shows that T. pseudomaculata is well-adjusted to the peridomicile. However, the epidemiological vigilance in this region is key due to this species' proximity to domiciles. |

OBJETIVO: Triatoma pseudomaculata, espécie peridomiciliar, é encontrada apresentando baixa taxa de infecção por Trypanosoma cruzi. Com o objetivo de identificar os possíveis reservatórios de T. cruzi, investigou-se a ocorrência desse triatomíneo no domicílio, bem como suas fontes alimentares. MÉTODOS: De janeiro de 2001 a julho de 2002 foram capturados 921 espécimes de T. pseudomaculata em 13 municípios do sul do Estado do Ceará. O conteúdo intestinal dos triatomíneos foi retirado, espalhado em disco de papel de filtro e analisado por precipitina para os seguintes anti-soros: ave, roedor, cão, gambá, lagarto, boi/cabra, gato, porco, barata e humano. A investigação da presença de T. cruzi foi feita observando-se parte do conteúdo intestinal dos insetos a fresco, entre lâmina e lamínula, e pela sua semeadura em meio de cultura. RESULTADOS: Do total examinado, 184 (90,6%) foram positivos para os anti-soros testados: ave (62,5%)>; roedor (33,7%)>; cão (20,1%)>; gambá (9,8%)>; lagarto (5%)>; boi-cabra (5%)>; gato (2,7%)>; porco (2,2%)>; barata (2,2%)>; humano (1,6%). As alimentações variaram de zero (não reagiram) a quatro da seguinte forma: não reagiram (9,4%), uma (57,1%), duas (26%), três (7%) ou quatro (0,5%). Das fontes alimentares identificadas apenas três espécimes (1,6%) foram positivos para T. cruzi. CONCLUSÕES: A baixa incidência de sangue humano mostra que T. pseudomaculata está bem adaptado ao peridomicílio. Porém, a vigilância epidemiológica na região sul do Estado do Ceará se faz necessária tendo em vista a proximidade da espécie ao domicílio. Universidade de São Paulo.
