Background and Objectives: Infections due to Pseudomonas aeruginosa, especially healthcare-associated infections, present a significant health problem worldwide. Drug resistance especially multidrug resistance in P. aeruginosa is on the rise. Thus the objective of this study was to determine the sensitivity pattern among clinical isolates obtained from the patients admitted to a tertiary care centre. Materials and Methods: A total of 484 non-duplicate P. aeruginosa isolates in 2014, 444 isolates in 2013, 350 isolates in 2012 and 460 isolates in 2007 were characterized according to their antibiotic susceptibility, and the trends over time were analyzed. Results: There were statistically significant increases in sensitivities of isolates P. aeruginosa from 2007 to 2014 to most of the routinely used antibiotics including Ciprofloxacin. Conclusions: A detailed genomic- and/or proteomic-level study for our isolates is much desired to understand this loss of resistance so that the same may be replicated in other bacteria.
