Main article: Bacterial phyla

There are several models of the Branching order of bacterial phyla, one of these was proposed in 2004 by Battistuzzi and Hedges,[1][2] note the coinage of the taxa Terrabacteria and Hydrobacteria.


Archaea




Thermotogae




Aquificae




Fusobacteria



Hydrobacteria
Polyphyletic PVC group


 Spirochaetes



 Planctomycetes 





 Chlamydiae 


FCB group

 


Chlorobi



Bacteroidetes





Paraphyletic Proteobacteria

 Epsilonproteobacteria 





 Solibacteres



 Deltaproteobacteria 




 


Alphaproteobacteria




Betaproteobacteria



Gammaproteobacteria



 




Terrabacteria


Actinobacteria



Deinococcus-Thermus






Cyanobacteria



Chloroflexi




Firmicutes
