1 Feb 2001 Group A beta-hemolytic streptococcus (GABHS) is a common cause of infections involving the upper respiratory tract and skin in children.
Streptococci are gram-positive aerobic organisms that cause many disorders, including pharyngitis, pneumonia, wound and skin infections, sepsis, and endocarditis. Symptoms vary with the organ infected. Sequelae of infections due to group A beta-hemolytic streptococci may include rheumatic fever and glomerulonephritis.
Hemolytic streptococci from humans can be classified into Lancefield groups A, B, C, F, G, and L on the basis of av RK Gunnarsson · 2020 · Citerat av 1 — Objective: The pathogenicity of beta-hemolytic Streptococcus group C (GCS) in patients attending for an uncomplicated acute sore throat is unknown and it was Rapidly test for Streptococcus pyogenes (Group A β-hemolytic Streptococcus, Strep A) in throat swab specimens in point-of-care* settings. It is here proposed that infection with group A beta-hemolytic streptococcus (GAS) was a major underlying cause of stuttering until the mid-1900s when penicillin Villkor: Group A Beta Hemolytic Streptococcal (GAS) Infection.

Streptococcus pneumoniae (a major cause of human pneumonia) and Streptococcus mutans and other so-called viridans streptococci (among the causes of dental caries) do not possess group antigens. Three types of hemolysis reaction (alpha, beta, gamma) are seen after growth of streptococci on sheep blood agar.
On blood agar, this S. pyogenes displays streptococcal group A antigen on its cell wall. 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).
