TABLE 6.
The GMT of anti-S. Enteritidis OMP IgY and IgA antibodies. Blood, bile, and cloacal swabs samples were collected at d14 of age (pre-challenge) and d35 of age (post-challenge). Samples were analyzed for anti-Salmonella OMP IgY and OMP IgA levels by ELISA (n = 6). Results were reported as geometric mean titers (GMT). Values with no common superscript differ (p < 0.05). The percent increase was determined as [(GMT of Vaccine + Challenge)–(GMT of Control)] ÷ (GMT of Control) × 100.
