|Categories:||Causes hemolysis; motile|
|Etymology:||Genus name: short spiral|
Species epithet: harmless
|Significance:||It is important to be able to differentiate this brachyspira from pathogenic brachyspiras.
[Of minor importance]
|Alternative Species Name(s):||Serpulina innocens, Serpula innocens, Treponema innocens.|
|Type Strain:||B256 = ATCC 29796 = CCUG 17081|
|Macromorphology (smell):||Forms small irregular colonies (0.1-1 mm in diameter) spred over the agar surface (the bactera "swarm" on the agar plate). Gives a week hemolysis on blood agar.|
|Micromorphology:||Thin (0.25-0.4 x 5.3-14.1 µm), spiral shaped and motile. Has 14-28 periplasmic flagella (endoflagella or axial filaments) per cell.|
|Gram +/Gram -:||G- (Uppträder som G -, men har en annan typ av cellvägg).|
|Metabolism:||Anaerobic, but aerotolerant|
|Other Enzymes:||Hippuricase -, tryptophanase (indol) -.|
|Disease:||B. innocensis regarded as a commensal and is, thus, not pathogenic. This bacterium is often present in the gut flora of different animal species.
|Hosts:||Pig, dog and poultry.|
|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.|
|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
