|Species/Subspecies:||Fusobacterium necrophorum subsp. necrophorum|
|Etymology:||Genus name: small spindle shaped rod.|
Species epithet: necrosis producing.
Subspecies epithet: see Species epithet.
|Alternative Species Name(s):||Bacteroides necrophorus, Fusobacterium necrophorum (Biotyp A)|
|Type Strain:||VPI 2891 = ATCC 25286 = CCUG 9994.|
||Small cream-colored metal shiny colonies. There are both strains that produce and not produce an hemolysis zone on blood agar. Smells like rancid butter (or boiled cabbage). Colonies fluoresce in neon green under long-wave UV-light.|
|Micromorphology:||Coccoid rods to thin, needle-shaped filaments. Non-motile.|
|Gram +/Gram -:||G-|
|Other Enzymes:||Esculinase -, lipase -, Tryptophanase + (= indole +).|
|Fermentation of carbohydrates:||Butyric acid is produced by fermentation.|
|Spec. Char.:||Temperature optimum: 37°C.|
|Virulence Factors:||Produces a leucotoxin directed against neutrophils and has LPS.|
|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:||Can convert lactic acid to propionic acid.|
