Oregano aqueous extract (OAE) mediated intestinal health by gut microbiota (Exp. 2). The relative mRNA expression of IL-4, IL-10, TNF-α and MUC2 in jejunum (A) and ileum (B) at d 42. At d 42, the secretion levels of SIgA in ileum (C). Data are expressed as means ± standard deviation. ^a−cTreatments with no common superscripts differ significantly (P < 0.05). IL, interleukin; TNF-α, tumor necrosis factor-α; MUC2, mucin 2; SIgA, Secreted immunoglobulin A
