Haplotype of carrier and noncarrier stallions for selected SNPs in ECA11 49572804–49643932^a

^aND, not determined; QH, Quarter horse; STB, Standardbred; TB, Thoroughbred; Rocky Mountain X, Rocky Mountain cross. *, Not monitored regularly beyond 3 months for shedding of the virus. The positive and negative phenotypes refer to in vitro CD3⁺ T lymphocyte susceptibility and resistance, respectively. The haplotype GGAGGT, which is associated with CD3⁺ T cell susceptibility, is highlighted in yellow, as described elsewhere (6). Each haplotype is highlighted with a different color.
