title: Isolation of genital mycoplasmas from blood obtained shortly after vaginal delivery.
abstract: 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.
