They belong to group A in the Lancefield classification system for β-hemolytic Streptococcus, and thus are also called group A streptococci. Figure 1. Streptococcus pyogenes (group A Streptococcus) on Gram stain.

SUMMARY Group A streptococci are model extracellular gram-positive pathogens responsible for pharyngitis, impetigo, rheumatic fever, and acute glomerulonephritis. A resurgence of invasive streptococcal diseases and rheumatic fever has appeared in outbreaks over the past 10 years, with a predominant M1 serotype as well as others identified with the outbreaks. emm (M protein) gene sequencing has

Of all the streptococci, GAS are the most pathogenic for humans. Group A streptococci (GAS) are defined gram-positive spherical-shaped bacteria that produce beta- hemolysis (lysis of red blood cells producing clear or transparent areas in special growth media) and appear usually as a chain of two or more bacteria and have molecules on their surface known as Lancefield group A antigens. Group A streptococci when grown on blood agar typically produces small zones of beta-hemolysis, a complete destruction of red blood cells. (A zone size of 2–3 mm is typical.) It is thus also called group A (beta-hemolytic) Streptococcus ( GABHS ), and it can make colonies greater than 5 mm in size.

2016-03-02 · Streptococcus pyogenes (group A beta-hemolytic) is sensitive to bacitracin and will not grow around the antibiotic- containing disc. The other beta-hemolytic streptococci are not sensitive to bacitracin and will grow next to the antibiotic-containing disc. group A streptococci Beta-hemolytic streptococci (esp. Streptococcus pyogenes) that produce human diseases, including pharyngitis, cellulitis, erysipelas, impetigo, otitis media, pneumonia, scarlet fever, necrotizing fasciitis, sepsis, sinusitis, and tonsillitis. They belong to group A in the Lancefield classification system for β-hemolytic Streptococcus, and thus are also called group A streptococci.

Group A hemolytic streptococci are responsible for most human streptococcal disease; group B hemolytic streptococci can cause serious problems in newborns. Incidence and characterization of beta-hemolytic Streptococcus milleri and differentiation from S. pyogenes (group A), S. equisimilis (group C), and large- colony pyogenes causes β hemolysis (Figure 2).
