Description:Under a magnification of 1000X, this trichrome-stained photomicrograph revealed the presence of a binucleated, flagellated Enteromonas hominis protozoa, which has been classified as a nonpathogenic microorganism.
E. hominis range in size between 4µm and 10µm, but are usually 6µm and 8µm. They have been observed as elongated or oval in shape. The number of nuclei within each protozoa ranges between 1 and 4, however, there are usually 2 that are situated at opposite poles. These nuclei are not distinct when observed in an unstained mount. These organisms resemble the cysts of Endolimax nana, and their flagella are usually not observable. The motility of E. hominis is described as being “jerky”.
