A new commercially available DNA strip assay (GenoType Mycobacterium CM/AS, Hain Lifescience, Nehren.. Germany) was evaluated for the ability to differentiate mycobacterial species. The test is based oil a PCR technique targeting a 23S rRNA gene region, followed by reverse hybridization and line probe technology. The GenoType CM is capable of identifying 23, the GenoType AS a further 14, species either alone or ill combination with one or more species. Both tests were evaluated with 156 mycobacterial strains composed of 61 validly published species including different subspecies, 6 not validly published species, and 3 strains other than mycobacterial species. All strains were precharacterized by sequencing of the 5' region of the 16S rRNA gene and biochemical tests. In total, results for 151 strains were interpretable. Concordant results were obtained for 137 (92.6%) of 148 mycobacterial strains with the CM assay and 133 (89.9%) of 148 mycobacterial strains with the AS assay, and all three non-Mycobacterium species were identified.
