Centers for Disease Control and Prevention. Since these two species are descendants of lineages that are highly divergent among eukaryotes, Malik et al. Trichomonas vaginalis is an anaerobicflagellated protozoan parasite and the causative agent of trichomoniasis.

The parasite does not appear to have a cyst form, and does not survive well in the external environment.

Higher prevalence among persons with multiple sexual partners or other venereal diseases. Although men and women can both become infected, it tends to victimize young women as it is typically asymptomatic in men. Laboratory Diagnosis Laboratory Diagnosis Microscopic examination of wet mounts may establish the diagnosis by detecting actively motile organisms.

Indeed, men can carry the disease unknowingly for years — though some men do develop itching and burning sensations which demand attention.

Treatment Information Treatment Information Treatment information for trichomoniasis can be found at: Trichomoniasis is very commonly found all over the world and still considered to be grossly underdiagnosed. The axostyle may be used for attachment to surfaces and may also cause the tissue damage seen in trichomoniasis infections.


A variety of virulence factors mediate this process some of which are the microtubules, microfilaments, adhesins 4and cysteine proteinases.

These extraordinary genome statistics are likely to change downward as the genome sequence, currently very fragmented due to the difficulty trochomonase ordering repetitive DNA, is assembled into chromosomes, and as more transcription data ESTs, microarrays accumulate. Trichomoniasisa sexually transmitted infection of the lx tractis a common cause of vaginitis in women, while men with this infection can display symptoms of urethritis.

The incubation period is 5 to 28 days.

The organism is able to maintain energy requirements by the use of a small amount of enzymes to provide energy via glycolysis of glucose to glycerol and succinate in the cytoplasmfollowed by further conversion of pyruvate and malate to hydrogen and acetate in an organelle called the hydrogenosome.

Five flagella arise near the cytostome; four of these immediately extend outside the cell together, while the fifth flagellum wraps backwards along the surface of the organism.

Unfortunately, the cure is not a vaccine and it does not provide protection from further unwanted attentions. Metamonads Sexually transmitted diseases and infections Parasites of humans.

Classically, with a cervical smearinfected women have a transparent “halo” around their superficial cell nucleus. This parasite was first discovered by French scientist Alfred Francois Donne, the same guy that discovered leukemia. Although some women who are involved with Trich may be asymptomatic like men, generally discharges provide warnings sufficient to justify medical action.

Direct immunofluorescent antibody staining is more sensitive than wet mounts, ttrichomonase technically more complex. Great teaching tool for health education classes Gentle reminder to stay safe, or get tested.
