Prevalence and Resistant Characteristics of Clinical Isolates of Enterobacter cloacae from 2002 to 2006

Objective To investigate the resistant characteristics of clinical isolates of Enterobacter cloacae.Methods Clinical isolates of Enterobacter cloacae were identified by Vitek-AMS and all drugs were tested by disk diffusion methods.Results The drug resistance of E.cloacae was increased to antibiotics,such as cephalosporins,quinolones,et al.Their non-susceptivity rates to ceftazidime and cefotaxime were 45.3% and 52.9% respectively.It was susceptible to cefepime and imipenem.Conclusion Multidrug-resistant strains of E.cloacae is remarkable.We should pay attention to change and use antibiotics reasonably in clinical chemotherapy.
