title: Pulmonary disease due to Mycobacterium arosiense, an easily misidentified pathogenic novel mycobacterium.
abstract: Mycobacterium arosiense is a newly described species. After noticing it was misidentified as Mycobacterium intracellulare by the commercial identification system GenoType CM (Hein, Nehren, Germany), we detected 4 such strains among 33 that were previously misidentified as M. intracellulare. Three more strains were found among unidentified mycobacteria not tested previously with GenoType. The first case of pulmonary disease due to M. arosiense is reported here, and the novel species, of which so far only one strain had been investigated, is further characterized.
