Veterinary bacteriology: information about important bacteria
|Category:||In the normal flora|
|Etymology:||Genus name: named after Louis Pasteur.|
Species epithet: of a bite.
|Type Strain:||ATCC 43325 = CCUG 12397 = NCTC 11617.|
|Macromorphology (smell):||Forms smoth and greyish to white colonies. No hemolysis on blood agar.|
|Micromorphology:||Nonmotile coccoid rod|
|Gram +/Gram -:||G-|
|Other Enzymes:||Ornithine decarboxylase -, tryptophanase +, urease +|

|Fermentation of carbohydrates:||
Other carbohydrates: mannose +.
|Disease:||Is an opportunist, which belongs to the normal flora of the mouth and nasal cavity and the gastrointestinal tract. May cause wound infections after dog and cat bites.
|Hosts:||Dog and cat|
|16S rRNA Seq.:|
||About 15 species have been described within genus Pasteurella, but the relationship between members within the closely related genera Actinobacillus, Haemophilus, Mannheimia and Pasteurella is very uncertain since none of these genera forms monophyletic clusters.|
|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...
