Abstract

One hundred and seventyone antenatal patients were examined for the presence of `large colony' mycoplasmas in the vagina, and for complement-fixing antibody to Mycoplasma hominis. In 25 patients the findings before and after delivery were compared. In patients from whom M. hominis was grown, antibody was twice as common after delivery, and the development of antibody was sometimes associated with pyrexia and signs of genital tract infection.
