Hemolytic streptococci are classified into 20 groups, A-V (I and J are omitted), according to serological differences in C-polysaccharide, a specific antigen of the organism. Group B streptococci (GBS), in particular, Streptococcus agalactiae, are known to cause serious infectious diseases including neonatal sepsis, pneumonia and meningitis resulting in high fatality rates and sequelae by secondary infection from the mother.
GBS serotype is identified by slide agglutination using heat-resistant polysaccharide antigens on the surface of the organism.
