A Case of Rectal Ureaplasma Infection and Implications for Testing in Young Men Who Have Sex with Men: The P18 Cohort Study.

Ureaplasma is a significant cause of nongonococcal urethritis. This is a case of rectal Ureaplasma found on culture in a young man who has sex with men not previously reported in the literature. Nucleic acid amplification tests are now standard of care for sexually transmitted infection testing, but they do not test for Ureaplasma and, therefore, may be missing important infections. Ureaplasma could have important implications in urethritis and rectal HIV transmission among men who have sex with men engaging in condomless anal intercourse. Further study of Ureaplasma's role as a rectal pathogen may be warranted.
