How do you treat Chilomastix mesnili?
Treatment with metronidazole is found to be highly effective in eradicating C. mesnili infection in common marmoset.
What does Chilomastix mesnili cause?
Chilomastix mesnili is considered nonpathogenic. The presence of cysts and/or trophozoites in stool specimens can however be an indicator of fecal contamination of a food or water source, and thus does not rule out other parasitic infections.
Does Chilomastix mesnili have a cyst stage?
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.
How is Chilomastix mesnili transmitted?
The cyst stage is resistant to environmental pressures and is responsible for transmission of Chilomastix. Both cysts and trophozoites can be found in the feces (diagnostic stages) . Infection occurs by the ingestion of cysts in contaminated water, food, or by the fecal-oral route (hands or fomites) .
Where is Chilomastix mesnili found?
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.
What is the characteristic feature of Chilomastix mesnili cyst?
Chilomastix mesnili cysts are usually lemon-shaped and measure 6-10 µm in length. They contain a large single nucleus with an eccentrically-located karyosome. The cystosome may also be visible.
What is the common name of Chilomastix mesnili?
In addition to humans, Chilomastix is found in chimpanzees, orangutans, monkeys, and pigs. It lives in the cecum and colon. C. mesnili has a similar life style to Giardia lamblia….

What is the shape of a Chilomastix mesnili cyst?
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.
What is the clinical presentation of Chilomastix mesnili?
Clinical Presentation. Chilomastix mesnili is considered nonpathogenic. The presence of cysts and/or trophozoites in stool specimens can however be an indicator of fecal contamination of a food or water source, and thus does not rule out other parasitic infections.
How do you get Chilomastix?
The cyst stage is resistant to environmental pressures and is responsible for transmission of Chilomastix. Both cysts and trophozoites can be found in the feces (diagnostic stages) . Infection occurs by the ingestion of cysts in contaminated water, food, or by the fecal-oral route (hands or fomites) .
What is the pathophysiology of Chilomastix infection?
Infection occurs by the ingestion of cysts in contaminated water, food, or by the fecal-oral route (hands or fomites) . In the large (and possibly small) intestine, excystation releases trophozoites. Chilomastix resides in the cecum and/or colon; it is generally considered a commensal whose contribution to pathogenesis is uncertain.
