The Royal College of Obstetricians and Gynaecologists (RCOG) issued their Green Top Guideline No 36 "Prevention of early onset neonatal Group B streptococcal disease" in 2003. This guideline clearly stated: "Routine bacteriological screening of all pregnant women for antenatal GBS carriage is not recommended, and vaginal swabs should not be taken during pregnancy unless there is a clinical indication to do so." But, "Intrapartum antibiotic prophylaxis should be offered if GBS is detected on a vaginal swab in the current pregnancy."
