Porphyromonas spp under electron microscopy[1]

Porphyromonas spp are a ubiquitous carbohydrate-fermenting Gram-negative black-pigmented anaerobic bacteria which are commonly associated with periodontitis in dogs[2].

Species which are pathogenic include:

  • Porphyromonas crevioricanis[3]
  • Porphyromonas cangingivalis[4]
  • Porphyromonas gulae[5][6]
  • Porphyromonas macacae

These pathogens are often cultured from the oral mucosa of dogs[7], where they are associated with plaque formation and gingivitis.

Other dentopathogenic bacteria are also found such as Actinobacillus spp and Eikenella spp.
