Aim of the work: To estimate the extent of carbapenemase producing Gram-negative bacteria in critically ill patients from Kasr El-Aini, Cairo University hospitals and to compare the Modified-Hodge test (MHT) as a phenotypic confirmatory test with the PCR as a gold standard genotypic method for their diagnosis. Patients and methods:95 bacterial isolates from 75 critically ill patients were collected over a period of six months from November 2016 to April 2017 from Cairo university hospitals. These isolates were subjected to susceptibility testing for carbapenems as per CLSI guidelines and were further phenotypically screened for the production of carbapenemase by MHT, then were subjected to genotypic analysis by multiplex PCR UR - http://172.23.153.220/th.pdf ER -
