The white, smooth, and glossy colonies were characteristic of M. tuberculosis subsp. canetti (Figure 1).
(A) IS6110 hybridization patterns of PvuII-digested genomic DNA. Lane 1, Mycobacterium tuberculosis Mt 14323 (reference strain). Lane 2, M. canetti strain NZM 217/94. Lanes 3 and 4, the strains isolated from French legionnaires with pulmonary tuberculosis (TB). (B) Spoligotyping patterns. Lane 1, M. tuberculosis H37Rv (reference strain). Lane 2, M. canetti strain NZM 217/94. Lanes 3 and 4, the strains isolated from French legionnaires with pulmonary TB.
