Strains were divided into six categories based on their resistance to a specific number of antimicrobial agent categories (penicillin and penicillins with inhibitors, cephalosporins, carbapenems, fluoroquinolones, aminoglycosides, and trimethoprim-sulfamethoxazole); fully susceptibility to all antimicrobial agents from all categories means “0”; “6” means resistance to at least one antimicrobial agent from each of the 6 categories.
