<p><strong>Background: </strong>Pseudomonas aeruginosa is an aerobic, motile, gram negative rod that belongs to the family, Pseudomonadaceae. They are often multidrug resistant due to intrinsic and acquired determinants. Continued emergence of resistance among P. aeruginosa to common antimicrobial drugs has been reported world-wide.</p><p><strong>Objectives: </strong>This study investigated the antimicrobial resistance as well as susceptibility patterns of isolates of P. aeruginosa in clinical

Antimicrobial susceptibility pattern of each isolate was carried out by the Kirby- Bauer disk diffusion method as per guidelines of Clinical Laboratory Standard Institute (CLSI).</p><p><strong>Results: </strong>Majority of isolates of P. aeruginosa were obtained from specimens of wound swab 89 (64.5%), pus 18 (13.05%), and urine 17 (13.1%). The isolated pathogens showed high resistance (91% to 96%) to cotrimoxazole and cefuroxime. Resistance rates to cefepime, ceftriaxone, cefotaxime, and gentamicin varied from 47% to 88%. All the isolates were comparatively better susceptible to meropenem, ciprofloxacin, amikacin and imipenem ranges from 76% to 87%.</p><p><strong>Conclusion: </strong>The results confirmed the occurrence of drug resistance of P. aeruginosa to anti-pseudomonal drugs. Imipenem, amikacin, ciprofloxacin and meropenem were found to be the most effective antimicrobial drugs. Therefore, judicious and rational treatment prescription is needed by the physicians to limit the further spread of antimicrobial resistance among the P. aeruginosa.</p><p>KYAMC Journal Vol. 9, No.-1, April 2018, Page 16-19</p>
