Recovery of viable bacteria of C. jejuni 11168H, ΔCj1324 mutant, and ΔCj1324 complemented strains from the gastrointestinal tracts of chickensa
| Site in gastrointestinal tract | Log no. of CFU of:
|
||
|---|---|---|---|
| 11168H | ΔCj1324 mutant | ΔCj1324 complemented strain | |
| Crop | 2.7 ± 0.2 | 2.6 ± 0.12 | 2.7 ± 0.14 |
| Gizzard | 2.5 ± 0.06 | 2.3 ± 0.08 | 2.5 ± 0.12 |
| Jejunum | 2.4 ± 0.1 | 2.3 ± 0.1 | 2.7 ± 0.1 |
| Ileum | 3.5 ± 0.12 | 3.3 ± 0.17 | 3.7 ± 0.19 |
| Cecum | 8.6 ± 0.13 | 7.4 ± 0.19b | 8.3 ± 0.08 |
| Cecal tonsils | 6.3 ± 0.13 | 5.5 ± 0.25b | 6.2 ± 0.08 |
a
Samples were recovered 6 weeks postinoculation (10 birds per strain). Log values presented are the geometric mean CFU per gram ± the standard errors of the means.
b
Differences from data for both the parent and the complemented strain are statistically significant (P < 0.05).
