Group B streptococcal disease in pregnancy.

Group B Streptococcal (GBS) infection in the pregnant female represents a challenging and often complex scenario which may cause deleterious effects in the neonate. In this paper we present three case reports of GBS infection in neonates with different outcome. A comprehensive review of the history, microbiology, clinical presentation and therapy guidelines is presented. Early diagnosis and institution of therapy are the most important factors which may have an impact on maternal and neonatal outcome.
