Magnitude of colonization and sepsis by group B streptococci in newborn infants

Abstract

Infants admitted to the Neonatal Intensive Care Unit at Tampa General Hospital, Tampa, Florida, were cultured for group B streptococci (GBS). Culture swabs were quantified for GBS to determine the magnitude of colonization in infected infants. Thirty-seven (17%) of the 217 infants cultured were positive for GBS. Six of these colonized infants developed sepsis, with blood cultures positive for GBS. Septic infants generally were colonized by large numbers of GBS (105 bacteria/culture swab) at two or more external skin sites, in comparison to aseptic infants, who were lightly colonized with GBS. The data suggest a possible correlation between magnitude of colonization by GBS at external skin sites and development of GBS sepsis in newborn infants.
