Serotype-Specific Acquisition and Loss of Group B Streptococcus Recto-Vaginal Colonization in Late Pregnancy

BACKGROUND Maternal recto-vaginal colonization with Group B Streptococcus (GBS) and consequent vertical transmission to the newborn predisposes neonates to early-onset invasive GBS disease. This study aimed to determine the acquisition and loss of serotype-specific recto-vaginal GBS colonization from 20-37+ weeks of gestational age. METHODS Vaginal and rectal swabs were collected from HIV-uni...

Group B Streptococcus (GBS) is a leading cause of serious neonatal infections. Although great progress has been made in preventing prenatal GBS, its colonization rate in different regions ofIran remains unknown. The objective of this study was to determine the colonization rate of GBS in pregnant women in Hamadan city, Central west of Iran. A group of 544 pregnant women were randomly selected a...

Maternal Obesity and Rectovaginal Group B Streptococcus Colonization at Term

OBJECTIVE To test the hypothesis that maternal obesity is an independent risk factor for rectovaginal group B streptococcus (GBS) colonization at term. STUDY DESIGN Retrospective cohort study of consecutive women with singleton term pregnancies admitted in labor at Barnes-Jewish Hospital (2004-2008). Maternal BMI≥30 Kg/m2 (obese) or <30 Kg/m2 (nonobese) defined the two comparison groups. The ...
