Arcanobacterium (/ɑːrˈkeɪnoʊbækˌtɪəriəm/) is a genus of bacteria. They are gram-positive,[1] non–acid fast,[1] nonmotile,[1] facultatively anaerobic,[1] and non–endospore forming.[1] They are widely distributed in nature in the microbiota of animals (including the human microbiota) and are mostly innocuous. Some can cause disease in humans and other animals (for example, Arcanobacterium haemolyticum infections).[1] As with various species of a microbiota (including their cousins in the genera Corynebacterium and Trueperella), they usually are not pathogenic but can occasionally opportunistically capitalize on atypical access to tissues (via wounds) or weakened host defenses.
