Susceptibility of Salmonella typhi and Brucella melitensis to the new fluoroquinolone rufloxacin (MF 934).
The antimicrobial activity of the new fluoroquinolone rufloxacin (MF 934) was evaluated by a standardized agar dilution method against recent clinical isolates of Salmonella typhi (67 strains) and Brucella melitensis (108 isolates). The results were compared with 5 other commercially available or investigational fluoroquinolones. All the isolates of S. typhi were inhibited by 1.0 mg/l of rufloxacin as compared to 4-8 mg/l for B. melitensis. Minimum inhibitory concentrations of rufloxacin against both S. typhi and B. melitensis were 4-16 times higher than those of other fluoroquinolones.
