BK virus (BKV) genotype–specific seroconversion after transplantation. Genotype specificity was determined for each patient on the basis of NAb titers. Percentages of patients who were (A) BKV DNA–negative and (B) BKV DNA–positive displaying NAbs against genotype I, II, IV, or multiple genotypes at the time of transplantation and 24 months post-transplantation are shown. (C) NAb titers against the replicative strain and the other genotypes are depicted at month 24 for patients who were BKV DNA–positive.
