|Taxonomy/phylogeny:||There are two taxonomic systems for genus Salmonella, but
the old system has mainly been abandoned. The names av the different subspecies of Salmonella enterica should
subsp. arizonae, Salmonella enterica
subsp. diarizonae, Salmonella enterica
subsp. enterica, Salmonella
subsp. houtenae, Salmonella enterica
subsp. indica och Salmonella
Only Salmonella enterica subsp. arizonae and Salmonella enterica subsp. enterica are included in VetBact Hundreds of serovars have been identified among these two subspecies and some of those that occur frequently in the latter subspecies are listed in the Term List under Salmonella serovars. .
We strongly recommend the new system to be used.
|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...
