Representative results from resistant (R) and susceptible (S) cattle genomic DNA single-stranded conformational analysis (SSCA) indicating the homozygous GT13 (175 bp) and heterozygous GT13/GT14 (177 bp) alleles. DNA from cattle genetically characterized as susceptible (SLC11A1s) or resistant (SLC11A1r) to standardized Brucella abortus in vivo challenge were used as controls (Cx) (A). DNA sequencing of PCR amplicons of SLC11A1 3′UTR confirmed the SSCA results evidencing the only one heterozygous genotype among all phenotyped susceptible and resistant cattle to BCG (B).
