A. Trichomoniasis, the third most common cause of vaginitis, is caused by the flagellated protozoan, Trichomonas vaginalis. The disorder is virtually always sexually transmitted.

B. Clinical features. Trichomoniasis in women ranges from an asymptomatic state to a severe, acute, inflammatory disease. Signs and symptoms include a purulent, malodorous, thin discharge (70%) with associated burning, pruritus, dysuria, and dyspareunia. Physical examination reveals erythema of the vulva and vaginal mucosa; the classic green-yellow frothy discharge is observed in 10-30%. Punctate hemorrhages may be visible on the vagina and cervix in 2%.

C. Complications. Infection is associated with premature rupture of the membranes and prematurity; however, treatment of asymptomatic infection has not been shown to reduce these complications. Trichomoniasis is a risk factor for development of post-hysterectomy cellulitis. The infection facilitates transmission of the human immunodeficiency virus.
