Description
Pyriform cell of small size (3-8 ~m) with an anterior nucleus transversely positioned and 4 flage lla inserted on one side of the nucleus (Fig. 4a). Convex dorsal face and flattened ventral face marked by a ridge. Three flagella are anteriorly directed ; the fourth is recurrent and associated with the ventral cytostomal ridge. This ridge does not extend to the posterior end , and the recurrent flagellum continues freely backward ( N i e , 1950) . Electron microscopic study has shown the diplomonad characters of Enteromonas. The vental narrow cytostomal ridge is supported by 2 microtubular fibers and one lip is more prominent than the other (Fig . 3a). Phagocytosis of bacteria occurs on the bottom of this ridge. Incompletely divided cells with 3 nuclei, each associated with a set of flagella have been observed. Resistant cysts are the transmission forms . Among the 8 species described , Enteromonas hominis is found in human intestine, and also in monkeys (Dobell , 1935) and rodents such as rabbits and probably other animals . Enteromonas caviae from guinea-pigs has been correctly described after hematoxylin staining by Nie (1950) . The list of described species is given in Kulda and Nohynkova (1978) ; electron microscopy by Brugerolle (1975a) .
