Abstract

Non-tuberculous mycobacteria (NTM) causing clinical disease have become increasingly common and more diverse. A new reverse line probe assay, GenoType Mycobacterium CM/AS (Hain Lifescience), was evaluated for identification of a broad range of NTM. It was compared with phenotypic (HPLC) and molecular (DNA probes, in-house real-time multiplex species-specific PCR, 16S rRNA gene PCR and sequencing) identification techniques, which together provided the reference ‘gold standard’. A total of 131 clinical isolates belonging to 31 species and 19 controls, including 5 non- species, was used. Concordant results between the GenoType Mycobacterium assay and the reference identification were obtained in 119/131 clinical isolates (90.8 %). Identification of and by the assay was problematic. The GenoType Mycobacterium assay enables rapid identification of a broad range of potentially clinically significant species, but some species require further testing to differentiate or confirm ambiguous results.
