Abstract: The study was undertaken over a period of 10 months at the department of Microbiology in a tertiary care hospital, Chennai. Gram negative clinical isolates of out-patients and in-patients who were admitted to different wards and ICU at our hospital were taken for our study. The clinical data was obtained from the respective units and wards of the patients. Two hundred and twenty gram negative isolates from various clinical specimen like pus, urine, blood etc. and the antibiotic susceptibility were studied. Majority of the gram negative organisms isolated were found to be sensitive to Amikacin, Imipenem, Piperacillin+Tazobactum and Cefeperazone+sulbactum. Most of the gram negative organisms were resistant to ampicillin and cephalosporins. The results of the retrospective study conducted in our tertiary care hospital demonstrates the distribution and their susceptibility pattern to most commonly used oral and parenteral antimicrobial agents. To prevent the spread of the resistant bacteria, it is critically important to have strict antibiotic policies while surveillance program for multidrug resistance organism and infection control procedures needs to be implemented.
