Group B Streptococcus infections in pregnancy

Streptococcus agalactiae is a cause of severe newborn infections1. The newborn is infected from the mother who can asymptomatically carry the organism in the vaginal flora. The incidence is about 1.5 per 1000 live births, and mortality is about 8.7%. It has been shown that appropriate detection of the agent in the vaginal flora of pregnant women followed by appropriate therapy of the newborn can significantly reduce the risk of infection1. Most current guidelines for the prevention of GBS perinatal disease are based on prenatal screening culture for vaginal GBS colonisation2. BD Group B Streptococcus Differential Agar (Granada Medium) is a selective medium for the isolation and identification of Streptococcus agalactiae (Group B Streptococcus) from clinical specimens. After anaerobic incubation for 18-24 h at 35+/-2°C, beta hemolytic strains of S. agalactiae produce pale orange to dark orange colonies. The orange pigmentation is very specific, serological or biochemical identification is not necessary for confirmation.
