Chilomastix

 [ki″lo-mas´tiks]
a genus of pear- or lemon-shaped parasitic protozoa found in the intestines of various vertebrates, including humans. All species are considered nonpathogenic or only slightly pathogenic, but one species, C. mesni´li, has been associated with rare cases of watery diarrhea.

Chilomastix

(kī'lō-mas'tiks),
A genus of protozoan flagellates parasitic in the large intestine of humans and other primates, and in many other mammals, birds, amphibia, and reptiles; it is ordinarily nonpathogenic, but one species, Chilomastix mesnili, may be an occasional cause of diarrhea in children.
[chilo- + G. mastix, whip]

Chilomastix,

A genus of protozoal parasite found in the intestines and occasionally causing diarrhoea.

The first ultrastructural survey (13) of a free-living retortamonad (Chilomastix cuspidata; [ILLUSTRATION FOR FIGURES 1.2, 2.2 OMITTED]) isolated during these studies confirms the similarity with parasitic species and that the retortamonads are a monophyletic group.
Three alternative hypotheses for the observed distribution of parasitic and free-living lifestyles within the Diplomonadida in relation to the outgroup Chilomastix, a retortomonad genus, are presented in Figure 3.
Parasites found, and their relative incidence (percentages in parentheses), were: Entamoeba coli (30.8); Endolimax nana (9.5); Dientamoeba fragilis (0.7); Giardia lamblia (4.8); Chilomastix mesnili (1.8); Hymenolepis nana (5.1); Trichuris trichiura (0.3); Ascaris lumbricoides (0.3); Enterobius vermicularis (0.3).

Hay que hacer notar que, la presencia de especies de protozoarios comensales tales como: Entamoeba coli, Endolimax nana, Iodamoeba butschlii y Chilomastix mesnili tambien demuestra la frecuente contaminacion del agua por heces de humanos y animales parasitados por protozoarios entericos [12].
