Reduced cecal Campylobacter jejuni colonization with yolks from hens immunized with a whole-cell lysate of C. jejuni . Individual and mean (▬) cecal C. jejuni counts of two-week-old co-housed broiler seeders (●) and sentinels (○) receiving standard feed supplemented with 5% (wt/wt) egg yolk from either HBSS/sham-immunized (left) or C. jejuni immunized (right) layers, from day six until the end of the experiment, are shown. Values are represented as log₁₀ cfu/g cecal content. At 10 days of age, seeder animals were inoculated with approximately 8 × 10³ cfu of C. jejuni KC40.
