A STUDY OF METALLO-BETA-LACTATAMASE PRODUCING PSEUDOMONAS AERUGINOSA IN CLINICAL SAMPLES OF S.S.G. HOSPITAL

摘要

Introduction: Pseudomonas spp. is common pathogen causing nosocomial infection. Acquired drug resistance is frequent in nosocomial isolates of Pseudomonas spp. Acquired metallo-?2-lactamases (MBL) in pseudomonas spp. have recently emerged as one of the most worrisome resistance mechanism because of their capacity to hydrolyze all beta-lactam antibiotics including penicillins, cephalosporins and carbapenems, with the exception of aztreonam. Aim: To detect metallo-?2-lactamase producing isolates of Pseudomonas aerugenosa from various clinical samples from patients admitted in our hospital. Material and methods : In this studyt we studied the prevalence, following standard methods of isolation and identification techniques of these bacteria from clinical materials Source : Samples of patients from different wards of S.S.G.Hosital are proceeded in Microbiology department , Medical College and S.S.G.Hospital Baroda. Results: Of total study of 150 isolates of Pseudomonas aeruginosa, 8 isolates are resistance to Imipenem . Of 8 samples , all are producing Metallo-Beta-Lactamase enzyme. Conclusion :Infection cause by MBL (metallo-?2-lactamase) positive isolates of Pseudomonas aerugenosa is important to identify because it poses not only therapeutic problem, but also a serious concern for infection control management.
