Microscopic agglutination test results in 40 paired sera samples by qPCR-based DNA detection
| MAT results | qPCR positive | qPCR negative |
|---|---|---|
| n (%) | n (%) | |
| Paired samples negative | 5 (50) | 19 (63.3) |
| Sero-conversion | 0 (0) | 5 (16.7) |
| Fourfold rise | 1 (10) | 2 (6.7) |
| Single high titer (≥ 1/400) | 2 (20) | 2 (6.7) |
| Possible past infection (MAT titer < 1/400) | 2 (20) | 2 (6.7) |
MAT = microscopic agglutination test; qPCR = quantitative polymerase chain reaction.
