Mycoplasma Hominis in cervical mucus of pregnant women

Abstract

 Mycoplasma Hominis（MH）is one of the normal genital flora in the urogenital tract of men and women. Whether MH is pathogenic or not remain to be clarified. The aim of this study was to investigate the prevalence of MH in pregnant women and association of MH with pregnancy outcomes. In this study, we investigated 616 specimens from 602 pregnancies. 21 specimens（3.4%）were positive for MH. Regarding maternal background, in the MH（+）group, the median age was significantly lower and Bacterial Vaginosis（BV）score ≧ 4 was significantly higher（p value: ＜ 0.01, ＜ 0.01）. Of the 454 pregnancies for which the outcome was known, there were significantly more cases of threatened preterm labor in the MH（+）group（p value: ＜ 0.01）. However, there was no statistically significant association between the presence of MH and mean delivery weeks, preterm labor, preterm premature rupture of the membranes and chorioamnionitis（p value: 0.226, 0.082, 0.862, 0.756）. In this study, BV score ≧ 4 were significantly more common in the MH（+）group. Previous study showed that there was a relationship between MH and bacterial vaginosis. Further research is needed on the possibility of mixed MH and other bacterial infections affecting perinatal outcomes.
