Differential prevalence of clinical tuberculosis is demonstrated among Eskimos for the ABO, but not for MN blood-group system. In the ABO system, types AB and B individuals have more tuberculosis than the other two types and the prevalence rate of moderate and far-advanced disease is more than threefold greater for type B and AB than for types A and O. In the MN system, type MM individuals have more clinical tuberculosis than the other two genotypes, and they also show greater prevalence rates of moderate and far-advanced disease compared with the MM and NN genotypes, but the differences are not statistically significant.
