Figure 2. IS6110 (a) and IS1081 (b) hybridization patterns of PvuII-digested genomic DNA. Lanes 1 to 3: clinical M. tuberculosis isolates; lane 4: the Somali isolate, So93; lane 5: the Canetti strain isolated in France in 1969; lane 6: the Swiss isolate, NZM 217/94; lane 7: M. tuberculosis Mt14323 (reference strain). Figure c represents spoligotyping patterns. Lane 1: M. tuberculosis H37Rv (reference strain); lane 2: the Canetti strain; lane 3: the Somali isolate, So93; lane 4: the Swiss isolate, NZM 217/94.
