In Vitro Activity of Imipenem and Colistin against a Carbapenem-Resistant <i>Klebsiella pneumoniae</i> Isolate Coproducing SHV-31, CMY-2, and DHA-1

<div>Phenotypic disc confirmatory tests. (a) Double-disk synergy test and disk potentiation test using cefotaxime (CTX) disk and ceftazidime (CAZ) disk are confirming the production of class C <i>β</i>-lactamases which were inhibited by APB. (b) The modified Hodge test is showing negative results for carbapenemase production, when the test isolate (Kp830) grew towards three carbapenem disks, including imipenem (IPM), meropenem (MEM), and ertapenem (ETP).</div>
