Total no. of isolates | ||
|---|---|---|---|---|
| In agreement | Different by A but same by B | Different by B but same by A | ||
| PFGE (A) and ERIC-PCR (B) | 41 (54.7) | 28 (37.3) | 6 (8.0) | 75 |
| AR (A) and ERIC-PCR (B) | 43 (57.3) | 17 (22.6) | 15 (20.0) | 75 |
| PFGE (A) and AR (B) | 68 (90.6) | 7 (9.3) | 0 | 75 |
a
A and B are different testing methods, as indicated in column 1. Isolates were found to be different when discrepant results were obtained and to be the same when consistent results were obtained by each method.
