Key resistances were used to select the isolates for WGS. The number of draft genomes obtained and the number of ARSP sentinel sites they represent are indicated. Antibiotics tested by ARSRL for each organism are abbreviated according to their WHONET codes: AMC amoxicillin/clavulanic acid, AMK amikacin, AMP ampicillin, CAZ ceftazidime, CIP ciprofloxacin, CRO ceftriaxone, GEN gentamicin, FEP cefepime, FOX cefoxitin, IPM imipenem, MEM meropenem, SAM ampicillin/sulbactam, SXT trimethoprim/sulfamethoxazole, TOB tobramycin, TZP piperacillin/tazobactam.
