Veterinary bacteriology: information about important bacteria

New names of taxa within the classification category phylum

Names of main developmental lineages (phyla) of bacteria were previously not regulated in the International Code of Nomenclature of Prokaryotes (ICNP), but after a vote among members of the International Committee on Systematics of Prokaryotes (ICSP), it was decided that this will happen in the future. It has also been decided that the name of a phylum should end with the suffix -ota and that the name should be based on a type genus within the phylum in question. Here are some examples of veterinary important phyla as well as a class that has been elevated to phylum and whose name also has been changed:

  • Actinobacteria ---> Actinomycetota
  • Firmicutes ---> Bacillota
  • Bacteroidetes ---> Bacteroidota
  • Epsilonproteobacteria (klass) ---> Campylobacterota
  • Chlamydiae ---> Chlamydiota
  • Fusobacteria ---> Fusobacteriota
  • Tenericutes ---> Mycoplasmatota
  • Proteobacteria ---> Pseudomonadota
  • Spirochaetes ---> Spirochaetota

At VetBact we will retain the old names in 2022 but in early 2023 we will start to use the new names, if the doubts that exist around these have been investigated.

New names of taxa within the classification category phylum

During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.
