Background: Aerobic nonfermenting gram-negative bacilli (NFGNB) are now emerging as important uropathogens. Methods: This study was done to know the significance of NFGNB other than P. aeruginosa and Acinetobacter spp. in Urinary Tract Infections (UTI) along with their antibiotic sensitivity pattern. Total 10,198 urine specimens received in eight months period from October 2013 to May 2014 were subjected to quantitative culture as per the standard procedures in the routine microbiology laboratory and the results were noted. Detailed clinical history and laboratory parameters (Total count, Urine microscopy: Pus cell and RBC) were gathered to know the significance of the organism. Results: Total 40.9% of the NFGNB isolates were clinical significant. Common risk factors associated with these NFGNB are ICU stay, previous hospitalization, catheterization and Diabetes Mellitus. Conclusion: Clinical correlation of NFGNB from urine is required before considering them clinically significant or contaminants.
