Differentially regulated genes indicative of the non-protective/pathological response to Y. ruckeri infection.

The differential regulation of genes at 72 h post-challenge in unvaccinated fish (UI72h) compared to uninfected unvaccinated fish (UU) was considered a non-protective/pathological response to Y. ruckeri infection as 83% of the group of fish in which these genes were identified died by 21 d post-challenge. Arrows indicate the direction of the fold change while NA indicates genes not assessed by real-time PCR.
