Anti-staphylococcal activity of temafloxacin, ciprofloxacin, ofloxacin and enoxacin

Abstract
Four fluoroquinolones were tested for antimicrobial activity against 300 isolates of staphylococci collected from medical centres throughout the United States. No cross-resistance to methidllin or oxacillin and the fluoroquinolones was observed. All four drugs were bactericidal agents and all ciprofloxacin-susceptible strains were inhibited at recommended breakpoint concentrations. Ciprofloxacin-resistant strains showed complete cross-resistance to the other fluoroquinolones. The relative potency of the study drugs as judged by MIC/MBC determinations was: temaflox-acin > ciprofloxacin > ofloxacin > enoxacin.
