Adherence of EPEC and EHEC strains to porcine intestinal explants
| Strain | Duodenum | Jejunum | Ileum | Caecum | Colon |
|---|---|---|---|---|---|
| E2348/69 | 13/13 (100 %) | 13/13 (100 %) | 11/11 (100 %) | 6/6 (100 %) | 1/6 (16.7 %) |
| CVD206 | 1/11* (9.1 %) | 5/10 (50 %) | 3/11 (27.3 %) | 0/11 (0 %) | 0/6 (0 %) |
| CVD206(pICC327) | 10/12 (83.3 %) | 12/12 (100 %) | 12/12 (100 %) | 4/12 (33.3 %) | 1/12 (8.3 %) |
| 85-170 | 0/6 (0 %) | 2/6 (33.3 %) | 14/15 (93.3 %) | 3/6 (50 %) | 0/6 (0 %) |
| ICC170 | 0/6 (0 %) | 0/6 (0) | 14/18* (77.8 %) | 0/6 (0 %) | 0/6 (0) |
| ICC170(pICC327) | 0/11 (0 %) | 5/11 (45.5 %) | 3/12 (25.0 %) | 4/12 (33.3 %) | 3/12 (25.0 %) |
*Although adhering bacteria were observed on HPS-stained sections, SEM demonstrated no A/E lesions for both Δeae strains CVD206 and ICC170 in all intestinal sites assessed.
