Invasive Group A Streptococcal Infections: T1M1 Isolates Expressing Pyrogenic Exotoxins A and B in Combination with Selective Lack of Toxin‐Neutralizing Antibodies Are Associated with Increased Risk of Streptococcal Toxic Shock Syndrome

Abstract
Analysis of 132 group A streptococcal (GAS) isolates from 151 invasive episodes, including streptococcal toxic shock syndrome (STSS), from 1983 to 19
