LOWIN- Low risk of infection progression, LATIN- risk of progression to a latent form of disease, PATIN- risk of progression to a patent form of disease, AVERIN- animals with SNPs combinations that did not fit into any of the mentioned groups. SNPs combinations defining each risk group are included in Supplemental Table 1. Genotypes not previously identified were classified as new genotypes.
