<i>Staphylococcus aureus</i> Isolates with Reduced Susceptibility to Glycopeptides Belong to Accessory Gene Regulator Group I or II

Abstract

We used multiplex PCR to determine the agr group membership of 18 European glycopeptide heterointermediate and intermediate-resistant Staphylococcus aureus strains. Of the 15 agr group I strains, 13 were resistant and 2 were susceptible to methicillin. The remaining three strains, like the United States and Japanese control strains, belonged to agr group II.
