The impact of the viability of Trichomonas vaginalis in urine on wet mount, culture, and PCR methods was assessed. To minimize the chance of false-negative results, urine specimens should be processed within 30 min of specimen collection and maintained at 37 degrees C, since temperature appears to affect the viability of Trichomonas.

Six isolates of a strain (MRP-MT) of Trichomonas vaginalis obtained from a woman before and after unsuccessful treatment with metronidazole had an appreciably lower susceptibility to metronidazole both in vitro in the aerobic tube assay and in vivo in the mouse assay than did control strains from patients cured with standard doses of the drug. Our results support recent evidence that metronidaz...

PCR analysis in two unusual occurrences of trichomoniasis, trichomonal empyema due to Trichomonas tenax and Trichomonas vaginalis in an infant urine sample, allowed us to obtain rapid and accurate trichomonad species identification. The weak sensitivity of wet preparations and the low viability of the flagellates can be remedied by the PCR method.

Trichomonas tenax is a flagellated protozoan commonly found in the human oral cavity but of unusual occurrence in pulmonary infections. We describe a case of a 67-year-old patient with glioblastoma who presented with severe pleurisy in the post-operative period while she was receiving high-dose corticotherapy. Several motile flagellated protozoa were identified in the pleural fluid. Trichomonas...

Trichomonas vaginalis has long been recognized as one of the most prevalent sexually transmitted infections. However, it is only in recent years that it has been appreciated that Trichomonas may play a critical role in amplifying human immunodeficiency virus (HIV) transmission. Given the evidence that T. vaginalis likely promotes HIV infection, the apparent high level of Trichomonas infection i...

The current study dealt with the detection of parasitic infection in cervix (114) vaginal swabs and urine samples taken from women who complain vaginitis visits to Department Obstetrics Gynecology at Al-Zahra Teaching Hospital, Al-Manathera General Hospital women’s medical outpatient clinics Najaf Governorate for period ( 1/5/2020) until (31/1/2021). It was detected that 23) were infected vagin...

Recent studies have demonstrated that the traditional 7-day course of metronidazole at a dosage of 200 mg. three times a day is not the only schedule effective in trichomoniasis (McClean, 1971; Csonka, 1971; Woodcock, 1972). It was decided to assess the efficacy of metronidazole 400 mg. four times a day for 2 days; this dosage would facilitate its administration with tetracycline 500 mg. four t...
