Table 6.
Strain resistance classification based on resistance patterns. LRS: Low Resistant Strain, MRS: Medium Resistant Strain, HRS: High Resistant Strain, CPD: cefpodoxime, CRO: ceftriaxone, CAZ: Ceftazidime, CEF: cefepime, CIP: ciprofloxacin, ATM: aztreonam, AMI: amikacin, GEN: Gentamycin, STX: trimethoprim/sulfamethoxazole. Breakpoints were established as reported by CLSI.
