摘要
OBJECTIVE: The purpose of this study was to evaluate the group B streptococcus (GBS) colonization rate in pregnant Korean women using selective culture media for GBS and to identify obstetrical complications and GBS-induced early-onset neonatal sepsis. METHODS: We evaluated 1,014 pregnant women who delivered at Busan Paik Hospital between January 2015 and December 2016. GBS colonization was assessed using chromID Strepto B agar. We evaluated GBS colonization in pregnant women, as well as the obstetrical complication and GBS-induced neonatal sepsis rates. RESULTS: The total GBS colonization rate was 11.6% (117/1,014). No significant increase was observed in the rate of pregnancy-related complications between the GBS-positive and the GBS-negative groups. Among the 134 neonates born to colonized mothers, early neonatal sepsis was reported in 2 neonates (1.5%); however, these were cases of non-GBS-induced sepsis. CONCLUSION: The GBS colonization rate (using selective culture media) in this study involving pregnant Korean women showed a higher colonization rate than that previously reported in Korea. Therefore, based on this study, we recommend GBS screening and the administration of intrapartum antibiotic prophylaxis in pregnant Korean women.
