|16S rRNA Seq.:|
||Seven species with standing in nomenclature has been described within genus Brachyspira. About 10 additional species have been reported, but their names have not been approved. Some of these species have been included in the phylogenetic trees and their names are given within quotation marks (see Fig. 97:5 and 6). All species within the genus Brachyspira are very closely related, but "B. corvi", B. aalborgi and B. pilosicoli differ significantly from the other species.|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
