Acquired drug resistance is frequent in nosocomial isolates of Pseudomonas aeruginosa. Acquired metallo-beta-lactamases (MBL) have recently emerged as one of the most worrisome resistance mechanism. The occurrence of an MBL positive isolate in a hospital environment poses not only a therapeutic problem, but is also a serious concern for infection control management. Hence the present study was conducted to detect the prevalence of MBL producing P.aeruginosa in a tertiary care hospital and to formulate antibiotic policy and plan a proper hospital infection control strategy to prevent the spread of these strains. A total of 100 Pseudomonas aeruginosa isolated from various clinical specimens over a period of one year from January 2011 to December 2011 in the Department of Microbiology, Mysore Medical College and Research Institute, Mysore were selected for the study. These isolates were subjected to antibiotic susceptibility testing and screened for MBL production using Imipenem- EDTA combined disc test. Out of the 100 Pseudomonas aeruginosa isolated, 22 (22%) were MBL producers. 36.4% were from pus, followed by blood (22.7%), urine (18.2%), CSF (13.6%), sputum and endotracheal aspirate (4.5%) respectively.100(100%) of the isolates were resistant to Ceftazidime, Cefotaxime, Cefepime and Piperacillin.16 (72.7%) were sensitive to Aztreonam, and 10(45.5%) to Imipinem. Multidrug resistance is common in P.aeruginosa. This study highlights the need to do surveillance to detect MBL producers, judicious use of antibiotics and implementation of appropriate infection control measures to control the spread of these strains in the hospital.
