Etiology of farcy in African bovines: nomenclature of the causal organisms Mycobacterium farcinogenes Chamoiseau and Mycobacterium senegalense (Chamoiseau) comb. nov

In 1973 the author proposed the name Mycobacterium farcinogenes for the causal agent of farcy in African bovines. Two varieties (subspecies) of this species were recognized by the author: M. farcinogenes subsp. tchadense and M. farcinogenes subsp. senegalense. Because the former is the type subspecies of the species, its name should have been M. farcinogenes subsp. farcinogenes. It is now proposed that these subspecies constitute two separate and distinct species: M. farcinogenes Chamoiseau and M. senegalense (Chamoiseau) comb. nov. IEMVT 75 (= NCTC 10955) and IEMVT 378 (= NCTC 10956) are herein designated the type strains of these two species, respectively.
