Recently, a study demonstrated that Salmonella infection can induce the innate immune antibody response [3], the cytokine signaling response, and the mRNA expression of immune cell signaling proteins (such as Toll-like receptors 2, 4 (TLR2, TLR4)), which significantly modulate the susceptibility of broiler chicken organs to Salmonella [3–5]. This evidence concerns the gene TLR2 and Salmonella Infections.
