Figure 1. . Computer-generated lane maps of genomic fingerprints of Mycobacterium tuberculosis strains isolated from the patient cohort (n = 65). PvuII-digested chromosomal DNA was probed with IS6110. Clusters 1 to 11 are indicated by vertical lines at the right margin. Asterisk indicates strain 97-275 (Beijing clone, obtained from K. Kremer, RIVM/NL) for comparison. Strains 7914 through 5687 show the Beijing genotype restriction fragment-length polymorphism pattern. The molecular weight marker and internal reference strain of M. tuberculosis (Mt 14323) are not shown.
