Mycoplasmas in pregnant women and in newborn infants

Mycoplasmas were isolated from 96 of 143 vaginal swabs of pregnant women on their first visit at the Prenatal Center. Ureaplasmas alone were isolated in a higher percentage than M. hominis alone or combination with Ureaplasmas. The isolated cultures at 36 weeks of gestation show no significant difference with the first visit isolation. Colonization of mycoplasmas were found in a higher percentage (93.3%) in the abnormal deliveries than in normal ones. Mycoplasmas were isolated also from throat swabs of 19 out of 141 newborn infants: the proportion of mycoplasmas positive infants was higher in low birth, weight children.
