Arcobacter spp

From Dog
Electronmicrograph of Arcanobacter spp[1]

Arcobacter spp (Epsilobacteria) are a Gram-negative, a microaerophilic, symbiotic, spiral-shaped bacteria normally present in the feces of dogs worldwide[2].

Species which have been reported in dogs include:

  • Arcobacter cryaerophilus
  • Arcobacter butzleri[3]
  • Arcobacter skirrowii[4]

These bacteria are normally isolated from food samples such as meat and shell-fish foods[5].

They are chemoorganotrophic with organic acids and amino acids used as carbon sources but carbohydrates are neither oxidized nor fermented.

Although normally nonpathogenic to dogs, they are an important emerging zoonotic bacteria[6].

They have been associated with diarrhea in humans in association with exposure to other microorganisms such as Campylobacter spp and Helicobacter spp.
