USP8 and Salmonella Infections: To verify the implication of some candidate genes in the process and acquisition of resistance to Salmonella infection in chicken, we quantified the expression of EMC6, FKBP5, NFU1, S100A12, FAM168B, PIGC, HESX1, and USP8 in cecum tissues of non-infected and Salmonella Typhimurium (ST)-infected Dagu chickens using qRT-PCR.
