Veterinary bacteriology: information about important bacteria
|Etymology:||Genus name: small ray rod. |
Species epithet: from pigs.
|Type Strain:||ATCC 33415 = CCUG 11624 = NCTC 12996|
|Micromorphology:||Non motile rod, usually 0.3-0.5 x 0.6-1.4 µm, but can also be more variable in length.|
|Gram +/Gram -:||G-|
|Other Enzymes:||Esculinase +, ornithine decarboxylase -, tryptophanase -, urease +|
|Biochemical Tests:||Methyl red -, Voges-Proskauer -, hydrogen sulfide -|
|Fermentation of carbohydrates:||
Other carbohydrates: Adonitol -, dulcitol -, D-fructose +, D-galactose +, inositol -, mannose +, melibiose +.
|Spec. Char.:||Does not require V-factor (NAD or NADPH) for growth. Cf. other Actinobacillus spp.|
|16S rRNA Seq.:|
||About 18 species have been described within genus Actinobacillus, 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.|
|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...
|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...
