A study of pseudomonas species isolated from clinical specimen with their antimicrobial sensitivity pattern

This study was conducted to isolate and identify different pseudomonads from various clinical specimens and to determine their antimicrobial sensitivity pattern. The study was conducted from July 2007 to June 2008, for a period of one year at Gauhati Medical College and Hospital. A total of 218 Pseudomonads were isolated and identity was established and confirmed using standard methods. Maximum isolates were from pus (24.72%) followed by Tracheal Swab (22.92%). Of the Pseudomonads maximum were Pseudomonas aeruginosa (92.2%) followed by Burkholderia cepacia (4.13%), Ralstonia pickettii (1.84%) and Pseudomonas putida (1.84%). The isolates were maximally sensitive to Imipenem (88.53%) followed by Piperacillin-Tazobactum (56.88%), these were least sensitive to Cefipime (16.06%).
