|Etymology:||Genus name: small spindle shaped rod.|
Species epithet: necrosis producing.
Subspecies epithet: sausage shaped.
|Significance:||[Of minor importance]|
|Alternative Species Name(s):||Fusobacterium necrophorum (Biotype B)|
|Type Strain:||Fn524 = ATCC 51357 = CCUG 42162.|
||Small greyish and semitranslucent colonies (1-2 mm i diameter), which give hemolysis on FAA plates.|
|Micromorphology:||Rodshaped (0,4-0,8 x 1-8 µm), where shorter cells (1-4 µm) are predominant.|
|Gram +/Gram -:||G-|
|Other Enzymes:||Esculinase -, lipase -, Tryptophanase + (= indole +).|
|Disease:||This bacterium is e.g. regarded as a secondary pathogen in ovine foot rot.
|Virulence Factors:||roduces a leucotoxin directed against neutrophils and has LPS, but not as much as subsp. necrophorum.|
|16S rRNA Seq.:|
||Within the genus Fusobacteria, 14 species have been described and 2 of these are divided into 7 sub-species. Fusobacteria are related to genus Streptobacillus, but the latter belongs to another family, namely Leptotrichiaceae.|
|Comment:||F. necrophorum subsp. funduliforme is less pathogenic than F. necrophorum subsp. necrophorum.|
|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...
