Abstract

Trichomonas vaginalis is the leading causative agent of non-viral, sexually transmitted infections worldwide. Infection with T. vaginalis is a marker of high-risk sexual behavior as it is frequently seen concomitantly with other STIs. The natural immune response to T. vaginalis infection increases both transmission of and susceptibility to HIV. While often asymptomatic, especially in men, manifestations of infection vary from a characteristic fishy-smelling discharge with pruritus to atypical pelvic inflammatory disease with the potential for pregnancy complications. Given the widespread prevalence of this infection and potential for significant complications; efforts need to be directed toward increased awareness, prevention, diagnosis and treatment. The most common diagnostic test, is a “wet mount”, which consists of simple microscopic examination of vaginal fluid in a saline preparation for organisms with characteristic quivering trichomonad motility. A focus on details of the interrelationship amongst causative agents of sexually transmitted infections has established that Mycoplasma hominis can combine forces with T. vaginalis in a symbiotic co-infection.
