Counts of E. coli K88 adhering to intestinal mucosa and enterotoxin expression in luminal content. Mucosal samples were obtained at 12, 24 and 72 h post infection and numbers of E. coli that adhered to jejunal (a) and ileal (b) mucosa were counted by plating serial dilutions of mucosal homogenates onto MacConkey agar plates. Intestinal digesta samples were collected at 72 h after infection and fold changes of genes encoding E. coli (c), STa (d), STb (e), LT (f) and K88 (g) were quantified by PCR analysis (n = 5). Results were expressed as means ± SEM. Specific IgY (Group III) versus Yolk powder (Group II); *, P < 0.05, **, P < 0.01. Yolk powder (Group II) versus Control group (Group I); #, P < 0.05, ##, P < 0.01. NS stands for Not Significant. The raw data was shown in Additional file 5: Figure S5
