Fig. 5From: Ileum terminal antibiotic infusion affects jejunal and colonic specific microbial population and immune status in growing pigsCorrelation analysis of immune markers levels in the jejunal and colonic mucosa and serum, dominant microbial communities counts in the jejunum and colon and SCFA concentration in the colon. The R package of “corroplot” was used for generating the heat maps. The blue represents a significant positive correlation, and the red represents a significant negative correlation. Asterisks indicate statistically significant difference from control: *P < 0.05. Total SCFA = total short-chain fatty acid; TLR2 = toll-like receptor 2; TLR4 = toll-like receptor 4; TLR5 = toll-like receptor 5; IL-8 = interleukin-8; IL-10 = interleukin-10; IFN-γ = interferon-γ; TNF-α = tumor necrosis factor-α; ZO-1 = zonula occludens-1; sIgA = secretory immunoglobulin A; IgG = immunoglobulin GBack to article page
