Pseudomonas aeruginosa is an opportunistic human pathogen and is the leading cause of nosocomial infections especially in immune compromised patients. In recent years, a considerable increase in the prevalence of multidrug resistance (MDR) P. aeruginosa has been noticed with high morbidity and mortality, hence requiring antibiotic susceptibility testing on a regular as well as a periodic basis. The present study was undertaken to determine the antibiogram of P. aeruginosa and its frequency of occurence from various clinical samples. A study was undertaken with 120 samples which were taken from patients of Dr. B. R. Ambedkar Medical College and hospital. The study was carried out in the Department of Microbiology, Dr. B.R.A.M.C, K. G. Halli, Bengaluru for a period of 9 months from July 2014- March 2015.A total of 120 clinically significant P. aeruginosa isolates were collected from different clinical samples, and processed using conventional microbiological methods. The strains were cultured and identified by standard microbiological techniques and Kirby- Bauer disc diffusion antibiotic susceptibility testing was done for each. Majority of isolates of P. aeruginosa (102/120, 85%) were obtained from specimens of pus, sputum, ear discharge and tracheal aspirates. Among 112 isolated pathogens 35(31.25%) showed resistance to aminoglycosides, 30(26.78%) to cephotaxime. Resistance rates to Piperacilin/tazobactam, ceftazidime, ofloxacin varied from 10-15(8.92% to 13.39%).10/112(8.92%)isolates were multi-drug resistant. All strains were found to be sensitive to imipenam, colistin (100%). The results confirmed the occurrence of drug resistant strains of P. aeruginosa. Imipenem, colistin, ceftazidime, pipperacillin-tazobactem and cefipime were found to be the most effective antimicrobial drugs. It therefore calls for a very judicious, rational treatment regimens prescription by the physicians to limit the further spread of antimicrobial resistance among the P. aeruginosa strains.
