| Strain | Inoculum a | Day 4 (fecal sample) b | Day 21 (cecal sample) c |
|---|---|---|---|
| TSB | 0 | 0 | 0 |
| 11168 | 7.5 × 106 | 1.6 × 104 (6/10 mice) | 1.1 × 106 (6/10 mice) |
| SCK7 | 8.1 × 107 | 1.3 × 106 (6/8 mice) | 2 × 105 (4/8 mice) |
| DM0170-2 | 7.5 × 107 | 0 (0/8 mice) | 0 (0/8 mice) |
| DM0170-6 | 8.5 × 107 | 0 (0/8 mice) | 0 (0/8 mice) |
| SC9 | 3.1 × 107 | 1.0 × 107 (6/8 mice) | 1.0 × 107 (5/8 mice) |
| SC5 | 3.3 × 107 | 4.0 x106 (7/8 mice) | 1.8 × 105 (6/8 mice) |

a
Inoculum cfu.
b
Average cfu/g fecal pellet for 8 mice (SCK7, DM0170-2. DM0170-6, SC13, SC5, and SC9) or 10 mice (NCTC11168). The ratio in parentheses relates the number of mice positive for C. jejuni colonization versus the number of mice challenged.
c
Average cfu/g cecal sample for 8 mice (SCK7, DM0170-2. DM0170-6, SC13, SC5, and SC9) or 10 mice (NCTC11168). The ratio in parentheses relates the number of mice positive for C. jejuni colonization versus the number of mice challenged
