Quinolone Resistance in Oligella Urethralis-Associated Urinary Tract Infection

The importance of oxidase-positive, nonfermentative, Gram-negative bacilli in a variety of pathological processes is becoming increasingly important. Oligella urethralis is an organism which is normally iso-lated as a commensal from the genitourinary tract. We have described one case of urinary tract infection caused by this organism. This isolated organism is found to be resistant to quinolones, while relatively sensitive to a wide variety of antibiotics. These findings clearly indicate that this organism may be an op-portunistic pathogen and that extensive application of quinolones may provide a selective pressure for the emergence of resistance. We believe that this is the firs report of isolation and quinolone resistance in Oligella in Iran.
