The detection of PBP 2a by the MRSA-Screen latex agglutination test
with 201 clinical coagulase-negative staphylococci had an
initial sensitivity of 98% and a high degree of specificity for
Staphylococcus epidermidis strains compared to PCR for
mecA. Determination of oxacillin MICs evaluated
according to the new breakpoint (0.5 µg/ml) of the National Committee
for Clinical Laboratory Standards exhibited an extremely low
specificity for this population.
