Prevalence and Antibiogram of Pseudomonas aeruginosa in a Tertiary Care Hospital of Haryana

Pseudomonas aeruginosa (P. aeruginosa) is a well-known invasive pathogen that can frequently cause severe infections in hospitalized patients. A major problem with P. aeruginosa infection may be that this pathogen exhibits a high degree of resistance to broad spectrum antibiotics. The main aim of this study is to know the prevalence of P. aeruginosa infection and its antibiogram in a tertiary care hospital. A total of 100 isolates of P. aeruginosa were isolated from different clinical samples using standard conventional techniques for six months, from June 2015 to December 2015. Antibiotic susceptibility testing was done by using kirby -Bauer disc diffusion method as per CLSI guidelines. In our study, highest resistance was observed for Cefuroxime (87%) and least resistance for Amikacin and Gentamicin (5% and14%) respectively. The most effective antibiotics were Colistin, Polymyxin B.
