Figure 2. 2a: Plot of the percentage of positive IgG anti-SE samples in serum and IgA anti-SE samples in the crop and lung flushes from non-infected hens (filled bar) versus infected hens (open bar) in trial 1. Numbers in parentheses represent the mean titres for each group. * Significantly different from non-infected controls (P<0.05). 2b: Plot of the percentage of positive IgA anti-SE sample lung flushes from non-infected hens (filled bar) versus infected hens (open bar) in trial 2. Numbers in parentheses represent the mean titres for each group. * Significantly different from non-infected controls (P<0.05).
