*RFLP, restriction fragment-length polymorphism; VNTR, variable number of tandem repeats; EAI4-VNM: East African–Indian family, Vietnam genotype; NR, not represented in spoligotype database (10); ND, RFLP typing not done.
†Difference in the number of direct repeat spacers between the spoligotypes of the index case-patient and that of the household case-patients. Genotypes based on spoligotyping in accordance with classification by Brudey et al. (10).
‡No. loci with different alleles.
