Antimicrobial Sensitivity of Locally Staphylococcus Isolates against Four Quinolones

Abstract

Ninety one isolates were collected from clinical samples included blood, urine, wound and burn swabs from different Baghdad hospitals during the period from 192011 to 1122011 . Result of coagulase test revealed that (59) of isolates were positive while others (32) isolates were negative. The sensitivity of isolates to four quinolones groups was tested, and results showed that (51.6%) of isolates were resistant to Norfloxacine , (46.2%) were resistant to Ofloxacine and (42.9%) were resistant to ciprofloxacine. While the lowest resistance was (29.7%) to levofloxacine. On the other hand, the coagulase positive Staphylococcus showed a high resistance in compare to that coagulase negative isolates . The range of the minimum inhibitory concentrations of ciprofloxacine were (8-512 µgml).
