😴 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of 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 taxonomically suspended (and therefore not recommended for medical use for now) until no later than 2029 in favour of Borrelia hermsii (Davis 1942) Steinhaus 1946 (Approved Lists 1980).
