APEC-induced gene expression of chicken cathelicidins (CATHs). Cells were infected with APEC for 3 h (primary macrophages and HD11 cells) or 6 h (primary macrophages). After that, RNA was isolated to determine gene expression of CATHs by qPCR analysis in A HD11 cells and B primary macrophages. Data are represented as mean  ±  SEM of three independent experiments of triplicate samples per experiment. **P ≤ 0.01;***P ≤ 0.005; ****P ≤ 0.001.
