Classification of the cows from the on-farm study (N = 99) in risk groups.

Risk Group	Genotypes codes (Nº of cows with a specific genotype)	Animals (N)	Animals (%)
PATIN	15 (1), 29 (1), 45 (1)	3	3.03
LATIN	25 (1), 26 (2), 32 (1), 39 (2)	6	6.06
LOWIN	5 (1), 31 (1), 34 (2), 48 (2), 62 (2), 67 (1)	9	9.09
AVERIN	16 (1), 17 (8), 19 (3), 20 (12), 22 (1), 24 (1), 28 (1), 30 (2), 40 (6), 41 (9), 43 (8), 44 (10), 47 (2), 54 (2), 55 (3), 56 (1), 57 (3), 59 (2). New genotypes (6).	81	81.81

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 corresponding to each risk group are included in Supplemental Table 1. Genotypes not previously identified were classified as new genotypes.
