Abstract:
OBJECTIVE To investigate the resistance to ?-lactam antibiotics and meropenem of non-ESBLs-producing Escherichia coli isolates.METHODS Non-ESBLs producers of E.coli isolates were detected by CLSI phenotypic confirmatory test,and susceptibility of these isolates to ?-lactam antibiotics and meropenem was tested by agar dilution method.RESULTS The resistance rate of these isolates to ampicillin,cefazolin and cefoxime was more than 60% and that to cefoperazone-sulbactam,cefmetazole and cefepime was 19.2%,23.8% and 31.8%,respectively,but most were susceptible to cefotaxime,ceftazidime,and meropenem.CONCLUSIONS The most isolates of non-ESBLs-producing E.coli are resistant to ampicillin and to the first and second generation cephalosporins,but they are susceptible to meropenem and the third generation cephalosporins.
