摘要
DNA from several species of fast growing mycobacteria displayed a characteristic restriction fragment length polymorphism (RFLP) pattern when hybridizated to a Mycobacterium fortuitum 16S rRNA gene fragment. The resulting patterns were identical when comparing different strains belonging to the same species. The RFLP results were consistent with those obtained by DNA-DNA hybridization studies. Using this approach, we have been able to identify the number of copies for 16S rRNA genes in several fast-growing mycobacteria.
