BACKGROUND: Knowing epidemiology of hospital acquired and community acquired P.aeruginosais important for deciding empirical treatment.

AIM: To know prevalence and antibiogram of hospital acquired and community acquired P.aeruginosa.

METHODS: A study done in Microbiology department of Shri Shankaracharya Medical College, Bhilai; from 01/1/2017 to 31/12/2017. Processing of sample was done by standard protocol and antibiotic sensitivity test was done according to CSLI guidelines.

RESULTS: Isolation rate of P.aeruginosa in our study was 3.35%. Hospital acquired strains were more resistant than community acquired. Carbapenems were the most sensitive drugs after polymixin B and Colistin.

CONCLUSION: Regular periodic surveillance to formulate rational treatment of P.aeruginosa is necessary because of their changing pattern of antimicrobial resistance.
