We report two instances of urethral-to-rectal transmission of Mycoplasma genitalium (MG) in men who have sex with men (MSM) couples. Such clear epidemiological correlation has to our knowledge not been published before. The urethral infections led to clinical symptoms, but the rectal infections did not. The rectum might serve as a reservoir for MG in MSM, but there is also some evidence from the literature that MG can cause proctitis. Our finding raises important questions about the role of MG as a pathogen among MSM. Any correlation with HIV transmission risk is currently unknown and needs further research.
我们报告了两例在男男性行为（MSM）伴侣中发生的生殖支原体（MG）从尿道传播至直肠的病例。据我们所知，这种明确的流行病学关联此前尚未见报道。尿道感染导致了临床症状，但直肠感染未引发症状。直肠可能是MSM中MG的储存库，但文献中也有一些证据表明MG可导致直肠炎。我们的发现引发了关于MG在MSM中作为病原体的作用的重要问题。目前尚不清楚其与HIV传播风险的任何关联，这需要进一步研究。
