Tannerella spp

From Dog
Electron microscopy of Tannerella spp

Tennerella spp are a Gram-negative, anaerobic zoonotic bacteria normally present in low numbers in the dog oropharynx and gastrointestinal tract.

Species which have been reported in dogs include:

  • Tannerella forsythia[1]

These bacteria have been associated with periodontitis in dogs and can cause cellulitis in humans from licking open wounds or from bites.

Other oropharyneal-dwelling bacteria are considered more pathogenic, such as Porphyromonas spp, Capnocytophaga spp, Prevotella spp, Aggregatibacter spp, Campylobacter spp and Eikenella spp[2].
