The full classification is: risk group = 2. — The risk group for United Kingdom has been imported on 2024-01-31. The full classification is: risk group = 2. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
- 🎓 Name mentioned 558 times in PubMed until 2026-06-11.
- 🙆 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 risk group of the species itself.
- 🧍 According to Bartlett et al. (2022), this species is an established human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology (Reading) 2022; 168:0. 🇬🇧
- 🧍 However, Chamoiseau [2] has already established two species, Mycobacterium senegalense (Approved Lists 1980) and Mycobacterium farcinogenes (Approved Lists 1980), to accomodate the farcy-associates strains of mycobacteria, thus eliminationg this source of confusion. Publication: Chamoiseau G. Etiology of farcy in African bovines: nomenclature of the causal organisms Mycobacterium farcinogenes Chamoiseau and Mycobacterium senegalense (Chamoiseau) comb. nov. Int. J. Syst. Bacteriol. 1979; 29:407-410.

- 🧍 Tsukamura [1] proposed rejection of the name Nocardia farcinica as a nomen dubium because some strains bearing this name were members of the genus Mycobacterium. Publication: Tsukamura M. Rejection of the name Nocardia farcinica Trevisan 1889 (Approved Lists 1980). Request for an Opinion. Int. J. Syst. Bacteriol. 1982; 32:235-236.
