Table 4. Relationship between hemolytic activity and pathotypes in 118 Escherichia coli isolates obtained from pigs with diarrhea in Korea
| Pathotypes | Hemolytic activity (%) |
| Hemolysis | Non-hemolysis | Total |
| ETEC | 39 ( 48.8) | 41 (51.3) | 80 ( 67.8) |
| STEC | 24 ( 85.7) | 4 (14.3) | 28 ( 23.7) |
| ETEC/STEC | 1 (100.0) | 0 - | 1 ( 0.9) |
| ETEC/STEC/EPEC | 9 (100.0) | 0 - | 9 ( 7.6) |
| Total | 73 ( 61.9) | 45 (38.1) | 118 (100.0) |
Data are expressed as number of hemolytic isolates (% for each pathotype).
ETEC, enterotoxigenic E. coli; STEC, Shiga-toxin producing E. coli; EPEC, enteropathogenic E. coli.
