Non-fermenters in urinary tract infection

Sixty four (4.4%) strains of non-fermenting gram negative bacteria (NFGNB) were isolated out of 1,380 bacterial isolates from 7,784 urine samples, of which 43 were isolated from male patients and 21 from female patients. P. aeruginosa was found to be the commonest (67.2%) followed by A. lwoffi (7.8%), A. anitratus and P. acidovorans testosterani (6.2% each), P. maltophilia and P. denitrificans (4.8% each), P. putida and P. vesiculare (1.5% each). Forty two(65.6%) of these isolates were isolated as pure cultures and 22(34.4%) as predominant organisms. Most of these isolates i.e. 50-88.8% were sensitive to Norfloxacin and Ofloxacin and 22.2% to 66.6% of these isolates were sensitive to Gentamycin and Cephalexin whereas 11.1% of these isolates were sensitive to Co-trimoxazole and Ampicillin. All of these isolates were resistant to Penicillin and Tetracycline.
