Abstract

Because the presence of in Argentina and Brazil has not been confirmed, a search was carried out in man and triatomine insects. Fifty-nine of 207 persons (28.5%) were infected when studied with one or more xenodiagnosis (40 /xenodiagnosis); 0.1% to 13% of 7,821 bugs' feces and 4% of 875 dissected midguts showed in Giemsa stained smears. One of 6,980 hemolymph samples and 1/875 salivary glands showed few flagellates which may have originated in the gut. They were not found in stained smears. Thirteen percent of 188 wild-caught domiciliary showed only in the gut and feces. Although the presence of could not be demonstrated, the study indicates that examination of pooled hemolymph and random samples of salivary glands and midguts can be carried out together with the usual examination of extracted feces in any species of triatomine, including those with salivary glands lacking the pink color present in the genus . Unless this procedure is widely used it will not be possible to differentiate and other possible trypanosome infections from those of nor to determine, therefore, the true prevalence of Chagas' disease in a given human population.
