Chilomastix mesnili Medical Laboratories

Chilomastix mesnili is a nonpathogenic flagellate that is often described as a commensal organism in the human gastrointestinal tract. Life Cycle View Larger 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) .

Chilomastix mesnili is of cosmopolitan distribution although found more frequently in warm climates. It is thought to be non-pathogenic although the trophozoite has been associated with diarrhoeic stool. Morphology of the cyst The cyst is 6-9 m It has a large single nucleus with a large karyosome.

For Entamoeba spp., C. mesnili, E. nana, and I. buetschlii, the software was only trained on labels that represented the morphologically distinct trophozoites. Cysts for those organisms were not trained in the model due to a low number of high-quality exemplars and poor quality of morphology on the trichrome stain.

Chilomastix mesnili. Trophozoite and cyst in fecal smear (trichrome stain, oil immersion). A larger trophozoite and a smaller cyst are seen side by side. The trophozoite has the typical pyriform shape and a nucleus with a large, central karyosome. The cyst is more rounded than lemon-shaped and the karyosome is seen in the nucleus. Trophozoites.

Chilomastix cuniculi is a non-pathogenic organism observed in the cecum of the rabbit. The trophozoite is pyriform with three anterior flagella, a large cytosomal groove near the anterior end and an anterior nucleus. The trophozoite ranges in length from 3-20 µm ( Pakes and Gerrity, 1994 ).

Regarding its phylogeny, Chilomastix mesnili belongs to the family Tetramitid~e, the ord Polymastigina, r and the class Mastigophora. The habitat of the parasite is th sm~ll intestine ofman. It is often the cause ofchronic orintermittent diarrhea. Cases ofinfec-tion by Chilomastix in man have been reported from nearly every locality in the world.

The trophozoites of C. mesnili are also pear-shaped and measure from 6 to 24 µm in length and 4 to 8 µm wide. The single nucleus usually has a prominent karyosome. The anterior flagella are difficult to see. The oral groove (cytostome) is sometimes seen near the nucleus. The image on the left is an iron hematoxylin stain (1000x). Wet Mounts

Abstract. Scanning electron microscopy of Chilomastix mesnili shows that the cysts are lemon-shaped with one end broadly rounded and the other conical. The trophozoite has five flagella coming out of the anterior end. Four of these are free and the fifth is attached to the body by an undulating membrane. The undulating membrane extends along.

This photomicrograph of an iodine-stained specimen, revealed some of the ultrastructural morphology exhibited by a flagellated, Chilomastix mesnili trophozoite. Note the organism's distinctly visible cytostome. Trophozoites are pear-shaped and usually measure 6-24 µm in length.

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.
