title: Novel ciprofloxacin-resistant, nalidixic acid-susceptible mutant of Staphylococcus aureus.
abstract: A ciprofloxacin-resistant, nalidixic acid-susceptible mutant of Staphylococcus aureus (F145) contained no mutations within gyrA, gyrB, grlA, and grlB or within norA or its promoter region. MICs and accumulation studies suggest the role of a novel multidrug efflux pump.
