a
Cloacal colonization of birds after seeders were infected with C. jejuni M1 and C. jejuni 13126 at 33 days of age. Birds were monitored by cloacal swabbing at 2, 5, 8, 12, and 15 dpi. Results are expressed as both the number and percentage of birds falling into each of three levels of colonization (H, D, and T). The total (T) includes positives from H and D colonization along with those obtained from enrichment culture.
