Resumo

Através da reação de hemaglutinação indireta para toxoplasmose. foram examinadas amostras de sangue de dez diferentes espécies de animais domésticos e silvestres, e de dois grupamentos humanos, um em Manaus e outro em Roraima. Em 108 animais domésticos 29 (90,6%) dos gatos (Felis catus) foi positivo para o teste, assim como 13 (68,4%) dos cães (Canis familiaris); 15 (60%) dos bois (Bos sp); 7 (41,2%) das galinhas (Gallus sp) e 6 (40%) dos patos (Cairina sp). Dos 104 animais silvestres examinados 3 (75%) das onças (Felis sp); 31 (63,2%) dos primatas (Saimiri sp) e 11 (61,1%) dos roedores (Proechimys sp) foram reagentes. A incidência de positividade nas populações humanas foram 70,6% e 64,9% em Manaus e Roraima, respectivamente.

Summary

Blood samples from ten different species of domestic and wild animals from two distinct areas were examined using an Indirect Hemagglutination test for toxoplasmosis. The human populations from the two areas, Manaus - Amazonas and indigenous Indians from the Territory of Roraima were also tested.

In a sample of 108 domestic animals, 29 (90.6%) of the cats (Felis catus) exmained were positive for the test, as were 13 (68.4%) of the dogs (Canis familiaris); 15 (60%) of the cattlee (Bos sp); 7 (41.2%) of the chickens (Gallus sp) and 6 (40%) of the ducks (Cairina sp). Of the 104 wild animals examined 3 (75%) of the wild cats (Felis sp); 31 (63.2%) of the primates (Saimiri sp) and 11 (61.1%) of the rodentes (Proechimys sp) were found to be reactive. The positive incidence in the human populations were 70.6% and 64.9% from Manaus and Roraima respectively.

The authors discuss the results in the light of the current knowledge of the epidemiology of toxoplasmosis. Emphasizing that trasmission mechanisms must exist for which there are, at present, no explanation.
