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).
However clinical microbiology laboratories generally do not have the ability (or the interest) to differentiate one species from the other. They are almost all normal inhabitants of the oropharynx. Streptococcus pneumoniae is also alpha-hemolytic but must not be confused with the viridans streptococci.
