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).
Alpha-hemolytic streptococci. Most of these species are referred to as a group â viridans streptococci. They are also sometimes referred to as âgreen strepâ owing to the color of blood agar surrounding the colonies. Many different species comprise the viridans streptococci. Notable examples include Streptococcus mitis, S. mitior, and S. sanguis. However clinical microbiology laboratories generally do not have the ability (or the interest) to differentiate one species from the other.
