Pseudomonas aeruginosa (P. aeruginosa) has been reported as the most commonly isolated organisms in hospitals. The increasing resistance rate of P. aeruginosa to the common antimicrobial drugs has been reported worldwide. The present study aimed to investigate the incidence and antibiotic susceptibility pattern of P. aeruginosa from inpatients of two hospitals. Out of 1235 patient specimens, a total of 108 (8.7%) non-duplicated P. aeruginosa clinical isolates were identified, majority of them were from males (59.3%) and from patients above 60 years (31.5%). The most common incidence rate was from male ward (43.5%) followed by female ward (20.4%). Majority of P. aeruginosa strains were isolated from sputum specimen (38%) followed by urine specimen (14.8%). The results showed that 42.6% of the isolates were sensitive to all antibiotics while 36.1 % were found to be resistant to more than three antibiotics. The study showed that maximum antibiotic susceptibility rate of P. aeruginosa isolates was against amikacin (83.3%) followed by ciprofloxacin (75.9%). The maximum resistance rates among P. aeruginosa isolates were against Piperacillin/Tazobactum (38.5 %,) followed by cefepime (32.4%). It was concluded that among P. aeruginosa isolates, amikacin was the most susceptible antimicrobial drug while piperacillin-tazobactam and cefipime were most resistant ones. Interventions and strategies to stop high resistance rate and optimizing therapy are needed.
