RESUMO

The activity of eight antimicrobial agents was determined against 115 isolates of Staphylococcus saprophyticus. All were susceptible to ampicillin, cephalexin, and trimethoprim-sulfamethoxazole and resistant to nalidixic acid and novobiocin. A bimodal pattern of susceptibility to erythromycin was observed: 80% were inhibited by 0.25 microgram/ml, whereas 13% required greater than or equal to 128 micrograms/ml. The following urethral staphylococci were susceptible to ampicillin, cephalexin, and nitrofurantoin but resistant to nalidixic acid: S. epidermidis, S. hominis, S. haemolyticus, S. warneri, S. simulans, and S. cohnii.
