Diversity of the 32-kilodalton protein gene may form a basis for species determination of potentially pathogenic mycobacterial species.

RESUMO

In this study, partial gene sequences of the mycobacterial 32-kDa protein gene were determined by PCR-based sequencing. A total of 50 strains representing 18 potentially pathogenic mycobacterial species were studied. In 10 cases, all three strains of the species studied were identical, and intraspecies variability was found in 6 cases. Thus, the 32-kDa protein gene may be a good target for identification of mycobacteria by PCR-based sequencing.
