Veterinary bacteriology: information about important bacteria
|Categories:||Causes hemolysis; spore forming; motile|
|Etymology:||Genus name: almost a Clostridium spp. |
Species epithet: named after the Argentinian bacteriologist professor Sordelli.
|Significance:||[Of minor importance]|
|Alternative Species Name(s):||Clostridium sordellii|
|Type Strain:||ATCC 9714 = CCUG 9284.|
||Form small colonies (1-4 mm in diameter), which may spread on th plate to a continuous film (the bacteria "swarm").|
|Micromorphology:||Large motile peritrichous rods (0.5-1.7 x 1.6-20.6 µm) with flagella. Produce oval, central or subterminal spores. Most strains are β-hemolytic on rabbit blood agar.|
|Gram +/Gram -:||G+|
|Other Enzymes:||Esculinase (-), lecithinase +, tryptophanase +.|
|Fermentation of carbohydrates:||
Other carbohydrates: Fructose v, galactose -, mannose v, ribose v, xylose -.
|Hosts:||Cattle, sheep, horse|
|16S rRNA Seq.:|
||Only two differens species have been descibed within the genus Paeniclostridium. P. sordellii is closely related toP. ghonii, for which the genus affiliation alse has been changed. Paeniclostridium is, as the namy implies, closely related to the genus Clostridium. Please note that the name of the bacterium in the tree (Fig. 31:2) is still Clostridium sordellii.|

|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...
