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
accordingly be:
Salmonella enterica
subsp. arizonae, Salmonella enterica
subsp. diarizonae, Salmonella enterica
subsp. enterica, Salmonella
enterica
subsp. houtenae, Salmonella enterica
subsp. indica och Salmonella
enterica
subsp. salamae.
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.
