  • a Overall consistency was 98.9%, with a PPV of 0.971 and an NPV of 0.992.

  • b The number of isolates with genotypes consistent with either susceptibility or resistance to a given antibiotic is shown, with the number of isolates with genotypes inconsistent with either susceptibility or resistance to a given antibiotic displayed in parentheses. Values of zero in parentheses have been dropped for clarity.
