  1. There was a higher percentage of Enterobacteriaceae isolates showing resistance to ceftazidime than to cefotaxime. The interpretative criteria used was based on CLSI M100-S20 (2010) [11] where for ceftazidime (Resistant ≤17 mm; Intermediate 18-20 mm; Susceptible ≥ 21 mm) and for cefotaxime (Resistant ≤22 mm; Intermediate 23-25 mm; Susceptible ≥ 26 mm)
