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 This protrusion is then withdrawn near its back and is again emitted in the front.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...

BACKGROUND Infection with Trichomonas vaginalis is one of the most common sexually transmitted diseases (STDs) in humans. The prevalence of infection in Iran has been reported between 2 to 8%, depending on deferent socio-cultural conditions. This study aimed to determine the prevalence of T. vaginalis in women referred to gynecologic clinics in Hamadan city, West of Iran. METHODS This descrip...

Trichomonas vaginalis is a parasitic protozoan which infects the urogenital tract and requires iron as an essential nutrient. Iron is known to upregulate various adhesins required for cytoadherance and other factors involved in pathogenesis. At mucosal surfaces, iron is chelated by lactoferrin resulting in low levels of free iron. However, pathogens have evolved mechanisms for an increased upta...

The aim of this study was to evaluate the immunocytochemistry (ICC) to diagnose trichomoniasis, particularly asymptomatic infections. By culture serial dilutions, ICC was able to detect 1 trophozoite/mL, while the culture was positive up to 100 trophozoites/mL. The ICC in vivo detection capability was assessed in vaginal secretions of mice experimentally infected and in vaginal swabs from asymp...
