Isolation of Group A Streptococci with Reduced In Vitro β-Lactam Susceptibility Harboring Amino Acid Substitutions in Penicillin-Binding Proteins in Japan

Streptococcus pyogenes (group A Streptococcus [GAS]) has long been regarded as being susceptible to β-lactams. However, amino acid substitutions in penicillin-binding protein 2X (PBP2X) conferring reduced in vitro β-lactam susceptibility have been indicated since 2019 in the United States and Icelan...
