Isolation of multidrug-resistant Enterobacter cloacae and comparison among clavulanate-tazobactam and sulbactam-synergy by using a double-disk synergy test
Abstract
False negative results of double-disk synergy test with Enterobacter cloacae are common, as AmpC-enzymes may mask ESBLs elaboration. We increased the sensitivity of the method by using both clavulanate- and tazobactam/sulbactam; hence, we suggest to use all the three inhibitors to screen ESBLs in AmpC ß-lactamases producing organisms.
