Fold change in gene expression of tilapia tissue samples in asymptomatic and symptomatic groups. Expression of Interleukin-8 (IL-8), Toll-like receptors (TLR7), major histocompatibility complex (MHC-II), Nuclear factor kappa B (NF-κB), chemokine receptors (CRs), Interleukin-1 (IL-1β) and Tumour necrosis factor α (TNF-α) genes by quantitative real-time PCR. The temporal expression was analyzed from asymptomatic and symptomatic tilapia from (A) liver, (B) Kidney, and (C) spleen tissue samples. The expression level in the asymptomatic group was regarded as 1.0, and thereby, the expression ratio of the symptomatic group was expressed as compared to the control group. The results are the mean ± SE (n = 3), and the vertical bars with an asterisk indicate significant differences between treatment groups (P < 0.05).
