Group B Streptococcus (GBS) is the most important bacterial agent in early-onset neonatal sepsis. Infection is usually acquired during labor in colonized women. Among pregnant women streptococcal colonization ranges from 2% to 34%, with highgest rates when using combined vaginal and anal culture in a selective broth medium. The aim of this study was to know the GBS prevalence in pregnant women controlled in our hospital and the real improvement in GBS recovery because the use of selective media. Among 2192 pregnant women enrolled, using selective medium, we identifed GBS in 19.8% of them. With non selective medium the prevalence would have reached only 12.7%. This finding support the systematic screening for GBS in our hospital, using selective medium only
