Species which have been identified as pathogenic in cattle include:
- Arcanobacterium pyogenes (previously Corynebacterium pyogenes or Actinomyces pyogenes)
- Arcanobacterium (Trueperella) abortisuis
- Arcanobacterium pluranimalium
Arcanobacterium pyogenes sometimes produces multiple, nodular abscesses and these bacteria also result in increased risk of disease and consequent culling of cows from dairy herds. In the cow mammary gland, these bacteria cause release of acute phase proteins, resulting in milk degradation and spoilage.
Diagnosis is based on laboratory culture of infected tissue or fluid obtained from diseased cattle.
