SLC11A1 gene (SLC11A1) codes for the natural resistance-associated macrophage protein (NRAMP1) (33) and some alleles of SLC11A1 have been shown to confer the resistance against MAP to BALB/C mice (34), to cattle against diseases such as tuberculosis (35, 36), brucellosis (37), salmonellosis (38), and conferment of udder immunity (39). This evidence concerns the gene SLC11A1 and brucellosis.
