Electron micrograph of Desulfomicrobium baculatum[1]

Desulfomicrobium spp are a Gram-negative, anaerobic proteobacteria found as a commensal in the oropharynx of dogs.

Species which are pathogenic to dogs include:

  • Desulfomicrobium orale
  • Desulfomicrobium baculatum

Although these are normally present in healthy gingiva of dogs, they have been associated with gingivitis and periodontitis[2].
