Abstract

By microdilution testing, 186 of 1,450 clinical isolates of Staphylococcus aureus were preliminarily classified as oxacillin resistant (MIC ≥ 4 μg/ml); 15 of these isolates gave conflicting results by alternative methods and were studied further. Only 2 of these (MIC > 4 μg/ml) were mecA positive; 13 were inhibited by oxacillin at 4 μg/ml. Significant numbers of S. aureus strains classified as resistant with an oxacillin MIC of 4 μg/ml may prove susceptible by other methods.
