title: Uptake of sparfloxacin and norfloxacin by clinical isolates of Staphylococcus aureus.
abstract: The amount of sparfloxacin uptake was higher than that of norfloxacin uptake in Staphylococcus aureus. Moreover, energy-dependent reduction in quinolone uptake, probably due to active efflux of the quinolone, was observed. The reduction in quinolone uptake appeared to be associated with quinolone resistance in S. aureus.
