|Species/Subspecies:||Fusobacterium necrophorum subsp. funduliforme|
|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.|
