Nonfermentative group of bacteria have been incriminated as emerging opportunistic pathogens, especially from hospital settings due to their increasing frequency of isolation from clinical specimens. Nonfermenters show natural resistance to a wide range of commonly used antibiotics. This study includes 50 isolates of nonfermenters from different clinical specimens like Pus ,Sputum, blood and urine obtained from patients attending SVS Medical college & Hospital from Jan2007 to March 2008.Out of 50 nonfermenters, Pseudomonas sp.(82%), Acinetobacter sp.(14%), Alcaligens sp.(4%) were isolated. Sensitivity pattern was Piperacillin (60%), Amikacin (52%), Ciprofloxacin (46%), Ceftazidime (46%), Cefotaxime (44%), Cefi-pime (36%), Gentamycin (24%). This study showed that non-fermenters were frequently isolated from clinical specimens and that they are becoming resistant to the routinely used antibiotics and hence should be taken seriously rather than regarding them as contaminants or commensals.
