Expression profiles of selected genes from the Salmonella shedding associated modules that were also up-regulated post-inoculation with Salmonella. Heat maps depicting the mean expression profiles of genes within Salmonella shedding associated modules (except magenta) that were up-regulated post-inoculation. In general, these genes had a higher mean expression in LS than PS at day 0. A majority of the genes in magenta module were not differentially expressed between days and thus the association of this module with Salmonella shedding counts may not be biologically relevant.
