We have tested the in vitro activities of eight fluoroquinolones against 160Brucella melitensis strains. The most active was sitafloxacin (MIC at which 90% of the isolates are inhibited [MIC90 ], 0.12 μg/ml). In decreasing order, the activities (MIC90 s) of the rest of the tested fluoroquinolones were as follows: levofloxacin, 0.5 μg/ml; ciprofloxacin, trovafloxacin, and moxifloxacin, 1 μg/ml; and ofloxacin, grepafloxacin, and gatifloxacin, 2 μg/ml.
