Changing Antibiotic sensitivity pattern in Gram Negative Nonfermenting Isolates: a Study in a Tertiary care Hospital

Background: Nonfermenting gram negative bacteria are a group of heterogenous,aerobic,nonsporing bacteria.They are saprophytic in nature and found as commensals in man and other animals. Objectives: This study aims at isolation, identification and antibiotic susceptibility pattern of nonfermenting gram negative bacteria. Material and Methods: 70 isolates from various age groups of both male and female patients were included in the study.The clinical specimens were collected under aseptic precautions and subjected to preliminary biochemical test for identification. Result: In the present study Acinetobacter baumanii and Pseudomonas aeruginosa were isolated.These Nonfermenting gram negative bacteria were isolated from Pus/wound swab, Blood, CSF, Tissue, Endotracheal tips and showed variability in their antibiotic susceptibility results. Conclusion: Nonfermenting gram negative bacilli are mainly seen in patients with serious underlying risk factors like prolonged stay in hospital, catheterization and various other health related infections.
