Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) is a zoonotic pathogen responsible for severe intestinal pathology in young chickens. Natural resistance-associated macrophage protein (NRAMP) family has been shown to be associated with resistance to intracellular pathogens, including Salmonella Typhimurium. The role of NRAMP proteins in macrophage defence against microbial infection has been ascribed to changes in the metal-ion concentrations inside the bacteria-containing phagosomes. The present study was conducted to investigate tissue-specific (liver, spleen and caecum) expression kinetics of NRAMP gene family (NRAMP1 and NRAMP2) in broilers from day 0 to day 15 after Salmonella Typhimurium challenge concomitant to clinical, blood biochemical and immunological parameters survey.
