Table 1.
Correlation between PFGE groups and mrp-epf-sly genotypes of S. suis serotype 2 isolated from 62 patients and 4 healthy pigs.
| PFGE groups (number found) | mrp-epf-sly genotypes (number found) | Patient isolates (% found) |
Healthy pig isolates (% found) |
|---|---|---|---|
| A (44) | mrp + epf − sly − (44) | 43 (69.4) | 1 (25) |
| B (2) | mrp + epf − sly − (2) | 2 (3.2) | 0 |
| C (4) | mrp + epf +/epf*sly + (4) | 4 (6.4) | 0 |
| D (12) | mrp − epf − sly + (11) | 8 (12.9) | 3 (75) |
| mrp + epf − sly − (1) | 1 (1.6) | 0 | |
| E (4) | mrp + epf − sly − (4) | 4 (6.4) | 0 |
ep f*: When used the same primer with the epf gene for PCR detection, the amplified fragment of this gene was approximately 1,278–3,000 bp.
