The hemolysis reaction along with one physiologic characteristic is sufficient for a presumptive clinical identification. Group A streptococcus (S. pyogenes) Alpha-hemolytic streptococci are very difficult to identify by phenotypic methods. In this study, a pyrosequencing method for the identification of streptococcal species based on two variable Identification S. haemolyticus can be identified on the species level using a variety of manual and automated methods. The most frequently employed are: the reference method (based on growth tests), API ID 32 Staph (bioMe´rieux), Staph-Zym (Rosco), UZA (a rapid 4-h method), and polymerase chain reaction and electrophoretic analysis of the 16S rRNA , hsp60 , or sodA gene sequence .

Related terms: Penicillin Optochin sensitivity allows for the presumptive identification of alpha-hemolytic streptococci as S. pneumoniae, although some pneumococcal strains are optochin-resistant. Other alpha-hemolytic streptococcal species are optochin -resistant. Alpha-hemolytic Streptococci Alpha-hemolysis (α-hemolysis) is a partial or “green” hemolysis associated with reduction of red cell hemoglobin. Alpha hemolysis is caused by hydrogen peroxide produced by the bacterium, oxidizing hemoglobin to green methemoglobin. It exhibit incomplete haemolysis with 1-2 mm wide. streptococci, especially those that are alpha-hemolytic, is not usually performed by most clinical microbiology laboratories.
