The rapid spread of acquired metallo-beta-lactamases (MBLs) among major Gram-negative pathogens is an emerging threat and a matter of particular concern worldwide. Carbapenems are among the few useful antibiotics against gram negative bacteria particularly those with extended spectrum beta-lactamase. Resistant to carbapenem is mediated by loss of outer membrane proteins and production of beta lactamase that is capable of hydrolyzing carbapenems.During this study period, 80 different clinical samples were collected from various hospitals of Raipur. All clinical samples were processed according to standard microbiological methods. Isolated GNRs were subjected to susceptibility testing against antibiotics by disc diffusion method according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. Carbapenem-resistant isolates were subjected to the detection of MBL production by different methods. Out of 80 samples, 28 (35%) samples showed significant growth. MBL production was observed in 20 samples.
