tetratrichomonas didelphidis (hegner & ratcliffe, 1927) andersen & reilly, 1965 is a flagellate protozoan found in the intestine, cecum, and colon of didelphis marsupialis. the parasitic protozoa used in this study was found and isolated in the intestine of opossums in pavlova starch-containing medium in florianópolis, state of santa catarina, brazil, from d. marsupialis and lutreolina crassicaudata. the strains were cultivated in diamond medium without maltose and with starch solution, ph 7.5 at 28°c. the specimens were stained by the giemsa method and heidenhain's iron hematoxylin. the light microscopy study of the trophozoites revealed the same morphologic characteristics as specimens previously described.
