Veterinary bacteriology: information about important bacteria
|Categories:||Causes hemolysis; spore forming; motile|
|Etymology:||Genus name: a small spindle. |
Species epithet: putrefactive.
|Significance:||[Of minor importance]|
|Type Strain:||ATCC 12464 = CCUG 4855 = NCTC 547.|
||Forms very small gray-whitish colonies, which quickly flow out onto the plate into a dense carpet (the bacteria "swarm"). Gives β-hemolysis on blood agar.|
|Micromorphology:||Large rods (0.6-1.9 x 1.9-35.0 µm), which usually are motile. Produce oval and subterminal spores.|
|Gram +/Gram -:||G+|
|Other Enzymes:||Esculinase +, lecithinase -, tryptophanase -.|
|Fermentation of carbohydrates:||
Other carbohydrates: Fructose +, galactose (+), mannose +, ribose v, xylose -.
|Virulence Factors:||C. septicum may cause severe infections by production f a hemolytic and necrotizing α-toxin.|
|16S rRNA Seq.:|
||About 180 differens species have been descibed within genus Clostridium. C. septicum is closely related toC. chauvoei.|
|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...
