| Abstract: | This is the first report on the ultrastructure of the Endolimax nana cyst. These cysts are mostly ovoid in shape and have a distinct cyst wall measuring 80 nm. The nuclear membrane is without pores or associated chromatin deposits. The cytoplasm does not have mitochondria or a Golgi apparatus but shows elongated tubular structures made up of a double row of ribosome-like particles. The nature and function of this structure is not known, but it appears to be characteristic of this species and has not been reported from any other intestinal ameba.
