|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.|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
