Highlights

Group B streptococci(GBS) refereed as Streptococcus agalactiae, is a Gram positive opportunistic pathogen which is beta hemolytic streptococci of Lancefield group B, that colonizes the gastrointestinal and gastrourinary tract upto 50 % of healthy individuals
The present study was done to know the prevalence of GBS colonization and the antibiotic susceptibility pattern in the antenatal pregnant women
Guidelines shows all antenatal pregnant women at 35-37 weeks of gestation are universally screened for GBS, and if colonized, intrapartum antibiotic prophylaxis to reduce the risk of transmission from mother to neonates

Summary

Introduction

Group B streptococci(GBS) refereed as Streptococcus agalactiae, is a Gram positive opportunistic pathogen which is beta hemolytic streptococci of Lancefield group B, that colonizes the gastrointestinal and gastrourinary tract upto 50 % of healthy individuals. The present study was done to know the prevalence of GBS colonization and the antibiotic susceptibility pattern in the antenatal pregnant women. Guidelines shows all antenatal pregnant women at 35-37 weeks of gestation are universally screened for GBS, and if colonized, intrapartum antibiotic prophylaxis to reduce the risk of transmission from mother to neonates. Antibiotic prophylaxis reduces the incidence of early onset Group B streptococcal disease by 36%, the incidence of Late onset Group B streptococcal disease has not been affected.[5] Henceforthy GBS remains the leading cause of bacterial disease in newborns with an overall incidence rate of ~0.3 infections per 1,000 live births. Evidence shows that GBS develop resistant to second line antibiotics in recent days and is emerging pathogen among adult and elderly populations which emphasise s the need to make alternative measures for preventing disease in both newborns and the elderly.[6]
