1Mean fold difference between infected and mock-infected birds at each time-point (n = 5 (6 for d 14)); P<0.05, positive values are up-regulated in infected birds and negative values are down-regulated in infected birds.—: no significant difference between groups or mRNA not expressed in one or both groups. Changes greater than three-fold are highlighted in bold.
