    Editor,—Trichomonas vaginalis infection occurs worldwide with an incidence of over 200 million infections per year.1 Clinical disease in women ranges from asymptomatic to severe vaginitis, and has been associated with preterm delivery2 and an increased rate of HIV-1 transmission.3

    The magnitude of T vaginalis associated morbidity, including risk of HIV-1 transmission, makes simple accurate diagnosis important especially in at-risk populations. Microscopic examination of a wet mount vaginal specimen is easy to perform but only identifies 40–60%4 of infections in comparison to culture. The In-pouch culture system (Biomed Inc, San Jose, CA, USA) is reported to be equally sensitive yet more practical than traditional culture methods.5 If proved sensitive, culturing of urine from female patients for T vaginalis might prove useful in population based screening …
