M. genitalium was detected in bothgenital and pharyngeal samples in 10.8% (7/65) ofpatients, and M. penetrans in 4.6% (3/65) of patients. M.pirum was found in only 2 cases, and no M. fermentanswas discovered.Conclusions: This study suggests that M. genitaliumand M. penetrans infections are common in patients withNGU/MPC. M. genitalium and M. penetrans may be trans-mitted by genital-genital or oral-genital sex, and maycause urethritis and cervicitis.展开更多
