PCR-restriction fragment length polymorphism analysis (PRA) of the hsp65
gene (A. Telenti, F. Marchesi, M. Balz, F. Bally, E. C. Bottger, and T.
Bodmer, J. Clin. Microbiol. 31:175-178, 1993) was applied to 108
mycobacterial isolates representing 34 species to evaluate its potential as
a rapid reference method. A total of 49 distinct patterns were obtained; 25
species were characterized by a single PRA pattern, while 9 species gave
more than one specific pattern. An algorithm describing these 34 species
(which includes five additional species and new subgroups of Mycobacterium
kansasii, M. abscessus, and M. peregrinum) is proposed. A relatively simple
and inexpensive method, PRA may be particularly helpful in routine clinical
microbiology laboratories.
