|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).|

For a long time, Rhodococcus hoagii was referred to Rhodococcus equi on VetBact, because we experienced some resistance to the name that is now considered to be the correct one, i.e. Rhodococcus hoagii. Now you can find the bacterium in question under the correct name in VetBact, but you can also find the bacterium when searching for the old name.Published 2021-10-10. Read more...
