group A strep·to·coc·ci (GAS),

a common bacteria that is the cause of strep throat, scarlet fever, impetigo, cellulitis-erysipelas, rheumatic fever, acute glomerular nephritis, endocarditis, and group A streptococcal necrotizing fasciitis. The prototype is Streptococcus pyogenes.

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. In addition, group A streptococcus infection may have immunologic sequelae such as rheumatic fever and acute glomerulonephritis.
