Abstract

Pseudomonas aeruginosa is an adaptable bacteria causing an extensive spectrum of infections and intrinsically resistant to many antibiotics. As antimicrobial resistance has increased due to many resistance mechanisms. This study was done to evaluate the antibiogram of Pseudomonas aeruginosa at a tertiary care centre. Thirty seven isolates were recovered from various specimens for a period of 6 months from June to December 2020  and the disc diffusion method was used for antibiotic susceptibility testing as per CLSI guidelines. Pseudomonas aeruginosa was found to be high (45.9%) in pus/wound than other samples. Antibiotic resistance rate of the isolates were 29.7%  to ceftazidime, 16.2% to Piperacillin-tazobactam, 27 % to gentamicin and ciprofloxacin, 16.2% to tobramycin and imipenem, 24.3% to meropenem, 27% to ciprofloxacin, 13.5% to aztreonam, 21.6% to amikacin, 24.3% to cefepime and levofloxacin, 21.6 to tigecycline. All strains were sensitive to colistin. 27% of the organism were found to be multidrug resistance. Hence periodic susceptibility testing can curb the resurgence of these bacterial pathogens.
