Natural occurrence of horizontal transfer of Mycobacterium avium- specific insertion sequence IS1245 to Mycobacterium kansasii.
Mycobacterium kansasii carrying IS1245, a highly prevalent insertion sequence among Mycobacterium avium isolates, was detected in a mixed culture of M. avium and M. kansasii. The insertion sequence was stable and able to transpose by a replicative mechanism in M. kansasii. These findings may have significant implications for molecular diagnosis and treatment outcome.
