Four fluoroquinolones were tested for antimicrobial activity against 300 isolates of staphylococci collected from medical centres throughout the United States. No cross-resistance to methicillin 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: temafloxacin greater than ciprofloxacin greater than ofloxacin greater than enoxacin.

Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.
