Adherence of group B streptococci to buccal epithelial cells in neonates with different gestational ages

Adherence of group B streptococci to buccal epithelial cells was determined in 81 neonates with different gestational ages. There was a significant curvilinear increase in adherence in premature neonates with decreasing gestational ages. Amniotic fluid did not inhibit attachment of group B streptococci to epithelial cells. Increased adherence of group B streptococci to premature neonates may explain, in part, the increased susceptibility of these infants to disease from this organism.
