In 2002, national guidelines recommended universal late antenatal screening of pregnant women for colonization with group B streptococcus to identify candidates for intrapartum chemoprophylaxis. METHODS We evaluated the implementation of the guidelines in a multistate, retrospective co...

Beta-hemolytic streptococcal isolates have been examined by counterimmunoelectrophoresis (CIE) with group B antiserum to determine whether this techinque is of value in the rapid identification of group B strains. Ninety stock cultures and 100 clinical isolates of beta-hemolytic streptococci including representatives of groups A, D, C, G, and B were inoculated into Todd-Hewitt broth; after incu...

Extracts from 19 of 29 group L streptococcal cultures reacted distinctly with antiserum against group B streptococcal type antigen X in coagglutination and immunodiffusion tests. The X antigen corresponded to those obtained by streptococci of serological groups B and G.
