Arcanobacterium spp, seen under light miscroscopy

Arcanobacterium spp are a genus of Gram-positive bacteria.

This group of Arcanobacteria have been implicated in a number of infections in dogs including otitis externa[1] and necrotizing fasciitis[2].

These bacteria are normally soil dwelling and infect dogs through commensal activity or via trauma.

Species which are pathogenic to dogs include:

  • Arcanobacterium haemolyticum
  • Arcanobacterium hippocoleae
  • Arcanobacterium phocae
  • Arcanobacterium canis
  • Arcanobacterium pluranimalium[3]

Resistance of this bacteria to tetracycline and macrolides has been reported.
