  1. Chilomastix mesnili is a flagellated protozoan generally regarded as nonpathogenic in the human host. Trophozoites are pear-shaped and usually measure 624 µm in length. The anterior end is rounded and contains a single nucleus with an eccentric karyosome.

  2. Chilomastix mesnili is a non-pathogenic member of primate gastrointestinal microflora, commonly associated with but not causing parasitic infections. It is found in about 3.5% of the population in the United States. In addition to humans, Chilomastix is found in chimpanzees, orangutans, monkeys, and pigs. It lives in the cecum and colon.

    Chilomastix has a resistant cyst stage responsible for transmission and a trophozoite stage, which is recognized as the feeding stage. Chilomastix mesnili is one of the more studied species in this genus due to the fact it is a human parasite.

  4. May 3, 2016 · The undulating membrane of Trichomonas and the spiral groove of Chilomastix may not be visible in all cases. Cryptosporidium oocysts can be demonstrated in acid-fast stains. Table 3: Differential Morphology of Protozoa Found in Stool Specimens of Humans: Amoebae-Trophozoites

  5. The flagellates Enteromonas hominis, Retortamonas intestinalis, and Pentatrichomonas hominis are considered non-pathogenic. These are less frequently encountered than Chilomastix mesnili, another non-pathogenic flagellates. The presence of cysts and/or trophozoites in stool indicates exposure to fecal contamination.

  6. Mar 12, 2018 · Infection by Chilomastix mesnili was determined by PCR method. Results: We identified nonpathogenic bacteria such as Proteus mirabilis and Escherichia coli in feces of normal common marmosets. Interestingly, C. mesnili was isolated from a healthy common marmoset by fecal centrifugation concentration and PCR.

  7. Chilomastix mesnili is a nonpathogenic intestinal commensal of humans. The trophozoite is pear-shaped, usually 10 to 15 μm long, with a large anterior cytostome, three forward-directed flagella, and a sharply pointed posterior end.

  8. The trophozoites of C. mesnili are pear shaped and measure 10-20 m in length. It has 1 large nucleus with a small karyosome and 3 flagella which extend from the nucleus at the anterior end of the parasite.

  9. The trophozoite is kite-shaped, with two nucleated sucking pads and four pairs of flagella (Fig. 62.9F). Trophozoites may be found in duodenal aspirate, but examination of faeces usually reveals the cyst form by which the disease is transmitted.

  10. Chilomasitx mesnili. The cyst of Chilomastix mesnili, shown on the right, is pear-shaped and measures 4 to 6 µm wide and 6 to 10 µm long. There is a single nucleus and a curved cytostomal fibril called the shepherd's crook. The image at right is a trichrome stain (1000x).
