Prevalence of nonfermenters in clinical specimens.

One hundred and thirty three non fermenting gram negative bacilli isolated out of 625 different clinical specimens were identified and characterised. Samples were exudate from chronic suppractive otits media (341), diabetic foot (117) wound (116) and blood (51). Of these isolates Pseudomonas aeruginosa 105(78.94%) predominated followed by Acinetobacter sp 8 [6.1%], Pseudomonas putrifaciens 6(4.5%), Flavobacterium sp 6(4.5%), Xanthomonas maltophilia 5(3.75%), Alkaligenes sp 3 (2.25). 31 (23.30%) were resistant to commonly used antibiotics. Amikacin 85 (63.90%) was found to be more effective than fluoroquinolones (27.8-48.12%).
