|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.|
|New families introduced within the order Enterobacterales|
The order Enterobacterales (formerly called Enterobacteriales) previously consisted of bacteria with different properties and phylogenetically, these bacteria were far apart. In order for the taxonomy to be more in line with phylogeny, some of these bacteria have, therefore, been sorted into 6 new families.Published 2022-04-13. Read more...
