Evaluation of the new GenoType Mycobacterium assay for identification of mycobacterial species.
The new commercial assay GenoType Mycobacterium, intended for the identification of mycobacteria, was evaluated with a panel of 197 strains belonging to 86 different taxa. The system, which relies on solid-phase reverse hybridization, is composed of two different kits: GenoType CM for the identification of more frequently detected mycobacterial species and GenoType AS for less common species. The sensitivity and specificity were 97.9% and 92.4% for the CM kit and 99.3% and 99.4% for the AS kit. Our results show that the system may represent a useful tool to substantially enlarge the number of mycobacteria that can be reliably identified in clinical laboratories.
