Hello Eric, Streptococcus genus contains both beta-hemolytic and alpha hemolytic species. S. pyogenes and S.agalactiae are beta-hemolytic but S.pneumoniae and viridans streptococci (common name for various Streptococci species that gives alpha hemolysis) are alpha hemolytic. In Staphylococci, S.aureus is the pathogenic one but S. epidermidis, S. saprophyticus are mostly.

Streptococcal colonies which do not result in any hemolysis are called. Group A strep (also known as Strep pyogenes) causes strep pharyngitis, tonsillitis,

Streptococcus pyogenes, or GAS, displays beta hemolysis. Some weakly beta-hemolytic species cause intense hemolysis when grown together with a strain of Staphylococcus. This is called the CAMP test. Streptococcus agalactiae displays this property. Clostridium perfringens can be identified presumptively with this test.

However, some group B streptococci are non-hemolytic and group D streptococci (discussed below) usually show alpha hemolysis or are non-hemolytic. Streptococcus pyogenes, often referred to as group A beta streptococci or GAS because they belong to Lancefield serologic group A and show beta hemolysis on blood agar, are responsible for most acute human streptococcal infections.

Description and Significance. Streptococcus pyogenes is a gram-positive bacterium that usually grows in pairs or chains. It has been classified as a beta-hemolytic streptococcus because when cultured on a blood agar plate all the red blood cells are ruptured by the bacteria (1).

Group A Streptococcus (Streptococcus pyogenes). These are beta-hemolytic, and bacitracin sensitive; cause septicemia, impetigo, pharyngitis, acute. ALPHA HEMOLYSIS- a greenish discoloration of the blood agar in a zone surrounding or beneath the colonies. Note the enhanced hemolysis in the shape of an arrow.

B. Beta-Hemolytic Strep – complete hemolysis Further classified by their Lancefield groups, which are the polysaccharide antigens on the cell surface. Note that not all strep species fit cleanly into one Lancefield group (or hemolysis pattern for that matter, like the Strep milleri group); for example, Strep dysgalactiae can be Group C or Group G.
