(Abstracted from J Matern Fetal Neonatal Med 2018;31(24):3293–3300) Maternal colonization with group B streptococcus (GBS) leading to neonatal sepsis remains a predominant cause of neonatal morbidity and mortality in the world. Many countries have adopted screening strategies, such as the antepartum GBS screening culture at 35 to 37 weeks of pregnancy (antepartum culture), to identify women who need intrapartum antibiotic prophylaxis (IAP) in order to avoid the GBS peripartum transmission to the fetus.
