In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans group, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as âgroup A strepâ and âgroup B strepâ).
The test detects the amino acid serine that has been cleaved from the hippuric acid. The second tube is positive for hippurate hemolysis and presumptive identification of GBS. Group B Streptococcus (GBS) are generally beta hemolytic on blood agar plates (right hand side).The colonies of GBS are gray to whitish-gray surrounded by a weak zone of beta hemolysis of the red blood cells in the culture medium.hese results indicate we have identified a group B Streptococcus. This is a picture of an agar plate with growth and hemolytic activity of group B streptococci (GBS) (on the left) and group A streptococci (GAS)(on the right).
