Blood obtained from three hundred and twenty-seven women within a few minutes of vaginal delivery was cultured for genital mycoplasmas (Mycoplasma hominis and T mycoplasmas). Twenty-six (8%) of the women had genital mycoplasmas isolated from their blood. Ten women had blood-cultures which contained M. hominis. Fifteen women had blood-cultures which contained T mycoplasmas. Both M. hominis and T mycoplasmas were isolated from the blood of one woman. Only one of two hundred and seventy-three blood-cultures obtained 1 or more days after delivery contained mycoplasmas. The isolation of M. hominis, but not of T mycoplasmas, from the blood was associated with vaginal colonisation and a serological response to the homologous isolate. Two of ten women whose blood contained M. hominis gave birth to stillborn infants. In contrast, there were only four (1.3%) stillbirths among the infants born to the three hundred and one women whose blood did not contain mycoplasmas. This difference is statistically significant.
在阴道分娩后几分钟内，从327名女性身上采集血液，培养生殖支原体（人型支原体和T支原体）。26名（8%）女性的血液中分离出了生殖支原体。10名女性的血培养物中含有解脲脲原体。15名女性的血培养物中含有T支原体。一名女性的血液中同时分离出了解脲脲原体和T支原体。分娩1天或1天以上采集的273份血培养物中，只有1份含有支原体。血液中分离出解脲脲原体而非T支原体，与阴道定植以及对同源分离株的血清学反应有关。血液中含有解脲脲原体的10名女性中有2名产下死产婴儿。相比之下，血液中不含支原体的301名女性所生婴儿中，死产仅有4例（1.3%）。这种差异具有统计学意义。
