Table 3.
Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for RdJ detection tests for the identification of ST105-SCCmecII (RdJ and non-RdJ) in the collection of Staphylococcus aureus studied.
| Genotype | Detection of ST105-SCCmecII | Total | |
|---|---|---|---|
| Negative | Positive | ||
| ST105-RdJ | 0 | 78 (true) | 78 |
| ST105-non RdJ | 4 (false) | 0 | 4 |
| ST4876 | 0 | 2 (false) | 2 |
| Other STs | 128 (true) | 0 | 128 |
| Total | 132 | 80 | 212 |
| Specificity: | 98.46% (94.55–98.81%) | PPV: | 97.50% (90.78–93.65%) |
| Sensitivity: | 95.12% (87.98–98.66%) | NPV: | 96.97% (92.48–98.81%) |
MLST and clone type (RdJ or non-RdJ) were performed using genomics and phylogenomics analyses. The parentheses correspond to the 95.00% confidence interval.
