New families introduced within the order Enterobacterales
Phylogenetic tree with certain species within the order Enterobacteriales. Species affected by the new family names are marked with red dots.
The order Enterobacterales is a very large taxon, which consists of bacteria with different properties. These bacteria form a number of distinct phylogenetic groups and in order to bring these groups into line with their taxonomy, 6 new families have been introduced together with family Enterobacteriaceae under the order Enterobacterales. These new families are: Budviciaceae, Erwiniaceae, Hafniaceae, Morganellaceae, Pectobacteriaceae and Yersiniaceae. Four of these families are represented on VetBact and the genera that are relevant are indicated within parentheses for the respected family: Erwiniaceae (Pantoea), Hafniaceae (Edwardsiella), Morganellaceae (Morganella and Proteus) and Yersiniaceae (Serratia and Yersinia). The bacterium Plesiomonas shigelloides has not yet been assigned to a new family, but it will happen. For the time being, therefore, this bacterium stands as inserta sedis. See reference no. 174 on the respective bacterial page in VetBact.
