GENITAL MYCOPLASMAS AND BIRTH-WEIGHT IN OFFSPRING OF PRIMI-GRAVID WOMEN

The relationship between colonization of pregnant women by ureaplasma and mycoplasma and the outcome of pregnancy in a study of 104 women is reported. There were eight abortions but no multiple births or stillbirths. Excluding abortions, the mean gestational length was 39.6 weeks and the corrected mean birth weight was 3.28 kilograms. There was no relationship between maternal colonization by genital mycoplasmas and reduction in birth weight of the offspring, but five of the eight women who aborted harbored ureaplasma, suggesting an increased trend toward abortion in women harboring ureaplasma.
