Introduced almost a decade ago, Flagyl (Metronidazole) is still the only acceptable systemic therapy available for trichomoniasis. Fortunately, the efficacy of Flagyl has remained at a very high level and there is no evidence that Trichomonas vaginalis has developed, or is developing, any resistance to it. However, there has always been the occasional case in which even very large doses of Flag...

Objectives: Trichomoniasis is one of the most common sexually transmitted diseases in humans and is caused by the protozoan Trichomonas vaginalis. Nowadays, increasing resistance to drugs such as metronidazole resulted in many problem, so new effective remedies are needed. In this study, we evaluate constituents of essential oil and anti-trichomonas activity of Rheum ribes. Materials and Method...

A colorimetric one-tube nested PCR was developed for the detection of Trichomonas vaginalis in clinical vaginal discharge specimens. A family of 650-bp specific DNA repeats from the T. vaginalis genome was targeted. There was no cross-reaction with human DNA or other infectious agents, including Pentatrichomonas hominis and Giardia lamblia. The colorimetric assay was applied as an adjunct to ne...

Trichomonas gallinae is a ubiquitous flagellated protozoan parasite, and the most common etiologic agent of epidemic trichomonosis in columbid and passerine species. In this study, free-ranging Pacific Coast band-tailed pigeons (Patagioenas fasciata monilis) in California (USA) were found to be infected with trichomonad protozoa that were genetically and morphologically distinct from T. gallina...

OBJECTIVE The objectives of this study were to 1) determine the prevalance and characterize the symptomatology of Trichomonas vaginalis (TV) infection in pregnant women on entry into prenatal care in an inner-city population; 2) compare conventional microscopic methods vs. culture techniques in diagnosing TV in both symptomatic and asymptomatic pregnant patients; and 3) correlate wet mount micr...

Background Sexually transmitted infections (STIs) are one of the major causes of acute illness, infertility, long term disability and death for millions of men, women and infants globally. Trichomonas vaginalis, Neisseria gonorrhea and Chlamydia trachomatis are well established agents of STIs leading to vaginal discharge in women. However, the prevalence and co infection patterns among symptoma...

(Current Biology 16, R395–R400; June 6, 2006) In our recent primer, "The Co-Evolution of Life and Earth," when discussing the evolution of hydrogenosomes ("Example 2"), we accidently wrote "Recently, genetic material was extracted from the hydrogenosome of Trichomonas ovalis .." There is no organism called ‘‘Trichomonas ovalis.’’ Rather, we meant to write ‘‘Nyctotherus ovalis.’’ For more detail...

undulans of Castellani was really allied to this species. There is no doubt that Lccschia undulans is nothing but a dying Trichomonas in its preliminary stage before rounding up. When a Trichomonas loses its active motility, it emits a finger-like protrusion in front and passes it on one side towards the back. This protrusion is then withdrawn near its back and is again emitted in the front. Th...
