[Bacteria condition of low genital tract of pregnant women and neonatal infection].
The swab from low genital tract of 74 cases of pregnant women, which were selected at random, were taken in labour and delivery room before delivery. A piece of placenta tissue and the swab of neonatal respiratory tract were obtained after delivery and were cultured in anaerobic and aerobic condition within 24 hours. Thirty-eight percent of bacteria that cultured in neonatal respiratory tract were the same species that obtained from maternal low genital tract and placentae. There were 15 infected neonates from 74 neonates, with positive culture in 9 neonates. Staphylococcus aureus played an important part in neonatal infection. Sixty seven percent of bacteria from the infected neonates were similar to the bacteria detected in low genital tract and placentae. Vertical transmission may play an important role in neonatal infection.
