Trichomonads lose motility quickly when at ambient temperature (3) and appear, in size and shape, similar to white blood cells, which are plentiful in women with discharge.
To the Editor: Trichomonads are flagellated protozoa with several species capable of infecting or colonizing humans.
Phylogenetic position of the trichomonad parasite of turkeys, Histomonas meleagridis (Smith) Tyzzer, inferred from small subunit rRNA sequence.
Using immunocytochemical techniques such as indirect immunofluorescence microscopy and western blotting, we have sought to identify and localize actin, tubulin, and centrin (a member of the EF family of calcium-binding proteins) in Chilomastix, Trimastix, Carpediemonas, a pelobiont, and a trichomonad (Weerakoon, unpubl, obs.).
It has been suggested that bird baths and artificial water sources could serve as a source of infection for naive birds; however, trichomonad persistence in water is not well understood.
Until now, both of the EF phylogenies (EF-1 alpha tree is shown in [ILLUSTRATION FOR FIGURE 1 OMITTED]) clearly and consistently suggested (a) that three amitochondriate protists, Glugea plecoglossi (microsporidian), Giardia lamblia (diplomonad), and Trichomonas tenax (trichomonad), represent an early-branching eukaryotic group; and that among them, the divergence of Glugea seems to be the earliest (1-5); and (b) that another amitochondrial protist, Entamoeba histolytica, is likely to have diverged after the divergences of some mitochondrion-containing protists, but is not likely to have diverged later than euglenoids, as suggested by the SrRNA tree (6).
