Degree of susceptibility: + = susceptible/sensitive (>21 mm), ++ = intermediate (16 to 20 mm), and +++ = resistant (≤15 mm). R = resistant; AMP10, ampicillin; CAZ30, ceftazidime; CRX30, cefuroxime; CN10, gentamycin; CPR5, ciprofloxacin; OFL5, ofloxacin; AUG30, augmentin; NIT300, nitrofurantoin; E15, erythromycin; DA2, clindamycin; NA30, nalidixic acid; C30, chloramphenicol; SXT25, sulfamethoxazole/trimethoprim.
