Bergey’s Manual of Systematic Bacteriology, 2^nd edition, Vol. 4

"Bergey's Manual", volume four, second edition, 2011.

In the beginning of this year, Vol 4 of the 2^nd edition of Bergey’s Manual of Systematic Bacteriology was at last published.  The following phyla, which are of importance in veterinary medicine, are included in this volume: Bacteroidetes, Tenericutes (Mollicutes), Fusobacteria and Chlamydiae. Taxonomic revisions have been introduced and we are updating VetBact accordingly. Here are some of the revisions:

• The two genera Chlamydia and Chlamydophila have again been combined into one genus: Chlamydia.
• The class Mollicutes has been transferred from the phylum Firmicutes to the new phylum Tenericutes, containing only this class.
• Many class names, which have earler been identical to the name of the corresponding phylum, have been revised, for instance Bacteroidetes to Bacteroidia. Other exemples are Spirochaetes revised to Spirochaeta, Fusobacteria to Fusobacteriia and Chlamydiae to Chlamydiia.

Vol. 5 is the last volume in the series to be published and bacteria of the phylum Actinobacteria will be treated in vol. 5.
