Multi abscessation with multinodular abscesses in a New Zealand white rabbit (Oryctolagus cuniculus) following Arcanobacterium pyogenes infection

摘要

Arcanobacterial infections can be seen in different animal species (cattle, pig, turkeys) but more rarely in rabbits. A female New Zealand white rabbit from a laboratory animal husbandry presented painful large masses on the right flank and around sternum coupled to gradual deterioration of the body condition. After euthanasia and necropsy, the presence of large abscesses containing yellow liquid pus enriched with cell debris was confirmed and congestion eventually coupled to small necrotic foci was also seen in internal organs (liver, spleen, lung and brain). The causative agent was microbiologically identified as Arcanobacterium pyogenes and it was the first description of multinodular abscessation due to this germ in rabbits.
