|Categories:||Causes hemolysis; motile|
|Etymology:||Genus name: a turning thread |
Species epithet: of the foot, referring to the source of isolation
|Type Strain:||T3552B = DSM 18691 = NCTC 13403|
||After 11 days on FAA plates with 10% blood colonies are 0.5-2.0 mm in diameter, flat, hemolytic with a metallic sheen|
|Micromorphology:||Thin, coiled (0.2-0.3 x 5-16 µm) and motile cells with 4-10 windings. Each cell has six periplasmic flagella where three of the originate from each end and they overlap in the middle of the cell. This used to be referred to as a 3:6:3 flagellation pattern.|
|Gram +/Gram -:||G -|
|Disease:||Digital dermatitis (cattle), ear necrosis and shoulder ulcer (pigs). The bacterium has also been isolated from the gingiva (gums) of pigs.|
|Hosts:||Cattle, pigs, sheep|
|16S rRNA Seq.:|
||About 25 different species have been described within the genus Treponema. There are different opinions among researchers about which should be regarded as separate species or only as subspecies of a certain species. Some researchers think that e.g. T. pallidum subsp. pallidum and T. pallidum subsp. pertenue should be regarded as different species, although they are very closely related from a phylogenetic point of view. See the phylogenetic tree (Fig. 188:3).|

We have refined the classification and made it possible to filter species and subspecies with respect to multiple properties.
