Fig 4. Salmonella loads in the ceca of chickens vaccinated in-ovo with CNP at 1wk-post-challenge.

Fig 4

At embryonic d18, broilers egg were vaccinated with either PBS (control) or 1000 μg CNP vaccine. At d7 of age, birds were challenged with live SE (1.0 × 109 CFU/bird). Ceca samples were collected from 3 birds/pen, pulled, and stomached for enumeration by plating on XLT-4 agar. Salmonella enumeration data were recorded as CFU/g of ceca and then transformed to Log 10 CFU/g of ceca for statistical analysis. Data analyzed by parametric Student t-test; Means+SEM.Bars. n = 6. "*" means P<0.05.
