“…So far, 2 Trichomitus species have been reported from primates, though each of them only once. T. wenyoni was originally described from laboratory rodents (Wenrich and Nie, 1949) and has been also reported from a rhesus macaque (Flick, 1954). However, no picture or drawing that would corroborate the observation was included in the latter study.…”

Extensive diversity of intestinal trichomonads of non-human primates

Despite the fact that the non-human primates are our closest relatives and represent a species-rich mammalian group, little is known about their intestinal protistan parasites/commensals. Particularly, the intestinal trichomonads represent a neglected part of the fauna of the primate digestive system. We have established 30 trichomonad strains isolated from feces of 11 primate species kept in 3 Czech zoos and performed an analysis of their SSU rDNA and ITS1-5·8S rDNA-ITS2. Our results showed that intestinal trichomonads are rather common among non-human primates. Molecular phylogenetic analysis showed that the strains are unexpectedly diversified, belonging to 8 or 9 distinct species. Interestingly, the vast majority of the strains from non-human primates belonged to the genus Tetratrichomonas while no member of this genus has been found in the human intestine so far. In addition, hominoid and non-hominoid primates differed in their intestinal trichomonads. Our results suggest that captive primates possibly may be infected by intestinal trichomonads of other vertebrates such as pigs, cattle, birds, tortoises and lizards.

“…Finally, Wienrich resolved five species infecting rodents that were differentiated by their size, number of flagella, and shape of their axostyle and undulating membrane: Trichomonas muris , Trichomonas minuta , Trichomonas parva , Pentatrichomonas sp., and Pentatrichomastix muris (Weinrich, 1924). T. parva was later considered to be synonymous with T. wenyoni (Weinrich & Nie, 1949) and Trichomonas muris with Tritrichomonas muris , to reflect the number of their anterior flagella (Daniel et al, 1971).…”

Tritrichomonas muris is a common flagellated protist isolated from the cecum of wild rodents. This commensal protist has been shown previously to alter immune phenotypes in laboratory mice. Other trichomonads, referred to as Tritrichomonas musculis and Tritrichomonas rainier, also naturally colonize laboratory mice and cause immune alterations. This report formally describes two new trichomonads, Tritrichomonas musculus n. sp., and Tritrichomonas casperi n. sp., at the ultrastructural and molecular level. These two protists were isolated from laboratory mice, and were differentiated by their size and the structure of their undulating membrane and posterior flagellum. Analysis at the 18S rRNA and trans‐ITS genetic loci supported their designation as distinct species, related to T. muris. To assess the true extent of parabasalid diversity infecting laboratory mice, 135 mice bred at the National Institutes of Health (NIH) were screened using pan‐parabasalid primers that amplify the trans‐ITS region. Forty‐four percent of mice were positive for parabasalids, encompassing a total of 8 distinct sequence types. Tritrichomonas casperi and Trichomitus‐like protists were dominant. T. musculus and T. rainier were also detected, but T. muris was not. Our work establishes a previously underappreciated diversity of commensal trichomonad flagellates that naturally colonize the enteric cavity of laboratory mice.
