|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...
