||||||||
| Type Strain: | Has not yet been defined. | ||||||||
| Macromorphology (smell):
| Like other brachyspiras, they do not form distinct colonies, but they rather swarm on the agar plate. The "colonies" which appear on the plate are irregular in shape and size. One colony probably descended from several original cells. Give strong hemolysis on blodagar. | ||||||||
| Micromorphology: | Motile | ||||||||
| Gram +/Gram -: | G- (appear as G - but has another type of cell wall). | ||||||||
| Metabolism: | Anaerobic, but aerotolerant | ||||||||
| Catalase/Oxidase: | |||||||||
| Spec. Char.: | |||||||||
| Disease: | Dysentery (in the pig) |
||||||||
| Hosts: | Pig, mallard | ||||||||

| Taxonomy/phylogeny:
|
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. | ||||||||
| Comment: | The species name has not been officially approve and should, therefore, be written: "Brachyspira suanatina". | ||||||||
