    abstract = {Thirty two <I>Escherichia coli</I> isolates recovered from diseased ducks diagnosed with colibacillosis in China between 2010 and 2011 were characterized for detection of Extended-Spectrum &#946;-Lactamases (ESBLs) by phenotypic screening and confirmatory test provided by the Clinical Laboratory Standards Institute and antimicrobial susceptibility profiles via agar disk diffusion and a broth doubling dilution method. Results showed 7 of the 32 <I>E. coli</I> isolates analyzed (21.87%) were found to be ESBL producers. The resistant rates of ESBL producers were &gt;28.6% against third generation cephalosporins and semisynthetic penicillins and as high as 100% against amoxicillin, ampicillin and ceftiofur. All 32 isolates were sensitive to imipenem, meropenem and cefepime and the susceptible rates of all 32 isolates to &#946;-lactam antibiotics in combination with enzyme inhibitors were higher than those of &#946;-lactam antibiotics alone. Therefore, ESBL-producing isolates had multi-drug resistance and enzyme inhibitors can partially solve the drug resistance problem.}
