TLR4 and Salmonella Infections: This candidate gene list includes genes previously reported to be involved in the regulation of host responses to Salmonella infection (SLC11A1, TLR4, CD14) or as having SNPs associated with Salmonella faecal shedding (CCR1), as well as those for which an association with Salmonella is novel (SIGLEC5, IGSF6 and TNFSF13B).
