[Association between Mycoplasma genitalium and preterm labor].

M. genitalium was identified by using polymerase chain reaction (PCR). The samples were obtained from the posterior vaginal fornix between 21-25 gestation weeks and investigated for PH, Gram Stain for bacterial vaginosis; Chlamidia trachomartis; Neisseria gonorrhoeae; Trichomonas vaginalis. Of 102 pregnant women, only five had a PCR-positive for M. genitalium. The occurrence of M. genitalium in posterior vaginal fornix at midtrimester is infrequent in pregnant women and unlikely to be a contributing factor for spontaneous preterm birth.
