Latimer RL, Shilling HS, Vodstrcil LA, et al. - In order to ascertain the prevalence of Mycoplasma genitalium (MG) in men who have sex with men (MSM) tested at each anatomical site, that is, at the urethra, rectum and/or pharynx, researchers conducted a systematic review and meta-analysis. Inclusion of 46 studies was done; these comprised 34 studies reporting estimates of MG prevalence at the urethra (13,753 samples), 25 at the rectum (8,629 samples) and 7 at the pharynx (1,871 samples). MSM commonly had detection of MG, particularly at urethral and rectal sites (5% to 6%). In symptomatic men, MG was more commonly detected at both sites, and HIV-positive men had more common detection of MG at the urethra. In the pharynx, detection of MG was uncommon. Site-specific measures are similar to those for chlamydia and will be valuable in informing testing practices in MSM.
