A new name has again been proposed for the bacterium known as Arcanobacterium pyogenes. This bacterium has also been referred to as Corynebacterium pyogenes and Actinomyces pyogenes. The proposed new name is Trueperella pyogenes and the reason for introducing this new genus is that genus Arcanobacterium is not monophyletic. It consists of two distinct lines of descent which don’t share a common ancestor.
The genus name Trueperella has been proposed in honor of the German microbiologist Hans Georg Trüper.
Trueperella pyogenes may cause abscesses, mastitis, pneumonia etc. in ruminants and in pigs and is of great importance in veterinary medicine.
