ABSTRACT
Estudos sobre a entrongiloidiase em paises em desenvolvimento sao relativamente raros quando comparados aos inqueritos epidemiologicos de outros helmintos transmitidos pelo solo. Esta observação fundamenta-se na rara ocorrência de Strongiloides stercoralis nestes paises quando comparada com a ascaridiase, tricuriase e ancilostomiase. Neste inquerito coproparasitologico as amostras fecais foram submetidas a tecnica da sedimentaçao espontanea (Hoffman, Pons e Janer) e ao metodo de Baermann-Moraes. Pelos dados obtidos das 439 amostras examinadas, 67,9 por cento (298) apresentaram resultados positivos e 32,1 por cento.

Tetratrichomonas didelphidis is a flagellated protozoan found in the intestine of opossums. The specimens were stained by the Giemsa method and by FLUTAX-2, an active fluorescent derivative of Taxol which binds to the ab-tubulin polimerized of microtubules of cells. Giemsa stain revealed the morphological features of trichomonads such as four anterior flagella, undulating membrane, axostyle and posterior flagellum. An intense fluorescence was observed in living trophozoites of T. didelphidis and Trichomonas vaginalis (used as control), incubated with FLUTAX-2. An analysis of the composition of the cytoskeleton of T. didelphidis will contribute to understanding the cellular morphology of the parasites. Key words: Tetratrichomonas didelphidis, microtubule cytoskeleton, fluorescent taxoid.
