|The revised taxonomy of the mollicutes (mycoplasmas)|
About 2 years ago, the taxonomy of mycoplasmas was revised at VetBact, because a research group had proposed that 5 new genera should be included together with the genus Mycoplasma. This also had consequences for higher taxa within the phylum, which was then called Tenericutes. Now another group of researchers has suggested that the new names should be rejected.Published 2023-10-03. Read more...
