title: Purulent Proctitis Caused byPrevotella biviain a Homosexual Male.
abstract: A 32-year-old homosexual male presented with suprapubic pain. Computed tomography showed rectal wall thickening. Flexible sigmoidoscopy showed small pockets of pus that were opened with mucosal biopsies, and additional pus was diffusely expressed from the rectal wall by applying blunt pressure with the biopsy forceps. Cultures from the pus grewPrevotella bivia. Symptoms resolved after treatment with doxycycline and metronidazole. Proctitis due toP. biviawas not previously reported.
