Changes in the expression of IFN-γ (A), MHC class II (B), CD4-1 (C), CD4-2 (D), CD8-α (E), CD8-β (F), IL-8 (G), IL-1β (H), and TNF-α (I) genes in the spleen of catfish challenged with E. ictaluri LAV and WT strains. Data are presented as fold difference of gene expression compared with values obtained for control uninfected cells. Samples were analyzed in triplicates from a pull of spleen of six fish and presented as mean ± SD. *Indicates significant differences compared to uninfected control (p < 0.05). abc Indicates differences within each time point (P < 0.05).
