Abstract

Background: In medical microbiology, Non-Fermentative group of bacteria have been incriminated as emerging opportunistic pathogens, especially from hospital settings. Non fermenting gram negative bacilli are a group of heterogeneous, aerobic (grow in presence of oxygen), non sporing bacteria. Materials & Methods: 150 isolates from various age groups of both male and female patients were included in the study. A detailed history was elicited and the clinical specimens were collected under aseptic precautions and subjected to preliminary biochemical test and further speciation was done. Results: In the present study Pseudomonas aeruginosa, Acinetobacter baumanii, Pseudomonas fluorescens were isolated of which Pseudomonas aeruginosa Was the most commonest. The non fermenting gram negative bacilli were Isolated 28. 68% from local wound infection, 22. 3% from post operative wound infection, 19. 9% from respiratory tract infections, 8. 37% from gastrointestinal tract infections, 6. 22% from urinary tract infections and 4. 68% from septicemia cases. Conclusion: The non fermenting gram negative bacilli infection is mainly seen in patients with serious underlying risk factors like prolonged stay in hospital, catheterization, underlying diseases like diabetes, malignancies and chronic pulmonary disease. Ciprofloxacin, Ofloxacin, Amikacin, Imipenem appeared to be effective drugs in treating non fermenting gram negative bacilli infections.
