E. Gradelski et al., Correlation between genotype and phenotypic categorization of staphylococci based on methicillin susceptibility and resistance, J CLIN MICR, 39(8), 2001, pp. 2961-2963
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(+) strain
s of other species of coagulase-negative staphylococci (CNS). However, at l
east 50% of the mecA-negative strains of these other species of CNS were fa
lsely classified as methicillin and oxacillin resistant.
