Resumo: | The population dynamics and the prevalence of chagasic infection of 352 dogs living in 108 rural houses infested by triatomines were studied. The region was divided into three sections according to increasing distances to an urban area. Each animal was identified by means of its particular characteristics and built, and its owners gave information about its habits. By means of xenodiagnosis, serology and ECG studies, prevalences of infection, parasitological-serological correlation, percentage of altered electrocardiographic outlines and percentage of houses with parasitemic dogs, were determined. The rural area showed a characteristic T. cruzi infection pattern and differences in the canine population parameters with respect to the other areas were observed: a higher proportion of puppies than adult dogs, a more sedentary population, higher prevalences of infection, as measured by xenodiagnosis, in dogs, and the highest proportion of bedroom insects infected with T. cruzi. It is assumed that the sedentary characteristics of the human population in that rural area impinge in the blood offer to the triatomine population, and the high percentage of parasitemic dogs of the area, contribute to the rise of "kissing ougs" infected with T. cruzi found in bedrooms. |

Estudou-se a dinâmica populacional e a prevalência de infecção chagásica de 352 cães vivendo em 108 moradias rurais infestadas por triato-míneos. A área foi dividida em três setores de acordo com suas crescentes distâncias em relação a um povoado urbano. Cada animal foi identificado mediante suas características particulares, e seus donos deram informações a respeito de seus hábitos. As prevalências de infecção foram determinadas por sorologia, correlação parasitológica-sorológica, percentual de traçados eletrocardiográficos alterados e o percentual de moradias com cães parasitados. A área rural mostrou um padrão característico de infecção por T. cruzi e observaram-se diferenças nos parâmetros de população canina em relação às restantes áreas: maior proporção de filhotes, maior população humana e canina sedentárias, maiores prevalências de infecção por xenodiagnóstico em cães e maior proporção de barbeiros infectados com T. cruzi nos cômodos da casa. Supõe-se que as características sedentárias da população humana desta área rural é fundamental para a oferta de sangue para as populações triatomíneas, e a elevada porcentagem de cães parasitêmicos dessa área contribui para o aumento de barbeiros infectados com T. cruzi encontrados nos quartos de dormir.
