Veterinary bacteriology: information about important bacteria
|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 bacterial phyla|
The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.Published 2023-03-01. Read more...
|The taxonomy of chlamydias|
Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
