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. | ||||||||
