|Fermentation of carbohydrates:||Most Brucella spp. do not produce acid by fermentation of carbohydrates.|
|16S rRNA Seq.:|
||Eleven species have been described within genus Brucella and this genus is closely related to genus Bartonella. From a phylogenetic point of view, B. abortus, B. canis, B. ceti, B. melitensis, B. neotome, B. ovis, B. pinnipedialis and B. suis represent the same species (B. melitensis), but due to different host specificities, they have been affiliated with different species.|
|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...
