🫡 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded pathogenicity of the species itself. This name is not taxonomically suspended any more in favour of Mycobacterium tuberculosis (Zopf 1883) Lehmann and Neumann 1896 (Approved Lists 1980).
