Capsular Polysaccharide of Group A Streptococcus

11 Jan 2019

Abstract excerpt

ABSTRACT Most clinical isolates of Streptococcus pyogenes elaborate a capsular polysaccharide, which is composed of hyaluronic acid, a high-molecular-mass polymer of alternating residues of N -acetyl glucosamine and glucuronic acid. Certain strains, particularly those of the M18 serotype, produce abundant amounts of capsule, resulting in formation of large, wet-appearing, translucent or “mucoid” colonies on solid...
