Pseudomonas aeruginosa is an important cause of hospital acquired infection especially in patients admitted in critical care units such as intensive care units and burn care units. In recent times, it has emerged as a widespread Multi Drug Resistant (MDR) pathogen which requires antibiotic susceptibility testing on a regular as well as a periodic basis. This study was carried with an aim to determine the antimicrobial resistance pattern and prevalence of MDR P. aeruginosa infection among burns patients at a tertiary care center. This retrospective study was carried out from July 2015 to May 2016. In this study 938 non repetitive wound swabs from patients admitted in burn unit were collected and the isolates were identified by conventional phenotypic methods, the antibiotic sensitivity testing of all P. aeruginosa isolates was done using Kirby-Bauer disc diffusion method and the results were interpreted according to the Clinical and Laboratory Standards Institute guidelines. Out of these 938 clinical specimens, Pseudomonas aeruginosa was isolated in 392(41.79%) samples. Out of these 392 isolates, 335 (85.45%) were found to be MDR P. aeruginosa. P. aeruginosa showed maximum sensitivity to meropenem and imipenem (30.1%) followed by levofloxacin (11.73%), piperacillin-tazobactum (10.2%). Carbenicillin, ceftazidime and cefoperazone were effective only in 1-5% isolates. Colistin was sensitive in 100% isolates.
