a
Acquired antimicrobial resistance genes mediating resistance to aminoglycosides [aac(3)-Id, aadA7, strA, strB], β-lactam [blaTEM-1B], sulfonamide [sul1] or tetracycline [tetA].
b
Amino acid changes in GyrA and ParC. For the fluoroquinolones resistance-mediating mutations, please see the resistance to ciprofloxacin (CIP) in Table 1 .
