Rectal Trichomonas vaginalis infection in South African men who have sex with men.

This study from South Africa highlights the importance of rectal Trichomonas vaginalis infection as a sexually transmitted infection among men who have sex with men (MSM). We report seven MSM presenting with rectal T. vaginalis infection. Two men presented with symptoms of proctitis; 5/7 had urethral coinfection with T. vaginalis. Rectal T. vaginalis infection should be considered in MSM in areas where genital infection is endemic.
