Positive correlation between methicillin and oxacillin
susceptibility test results and the detection of the
mecA gene was observed for
Staphylococcus aureus, S. epidermidis, and S. haemolyticus as well as
among mecA+ strains of other species of
coagulase-negative staphylococci (CNS). However, at least 50% of the
mecA-negative strains of these other species of
CNS were falsely classified as methicillin and oxacillin resistant.
