IS986 of Mycobacterium tuberculosis belongs to the IS3-like family of insertion sequences, and it has previously been shown to be present in multiple copies in the chromosome of M. tuberculosis. In this study we investigated the value of a IS986-based DNA probe in the diagnosis and epidemiology of tuberculosis. IS986 was found only in species belonging to the M. tuberculosis complex. Independent isolates of M. tuberculosis complex strains showed a very high degree of polymorphism of restriction fragments which contained IS986 DNA. In contrast, Mycobacterium bovis BCG vaccine strains as well as clinical isolates of M. bovis BCG contained one copy of IS986, which was present at the same location in the chromosome. Different M. tuberculosis isolates from a recent M. tuberculosis outbreak showed an identical banding pattern. We concluded that IS986 is an extremely suitable tool for the diagnosis and epidemiology of tuberculosis.
