Introduction


[]


Tannerella forsythia

(A) A wild-type T. Forsythia cell. (B) A mutant T. Forsythia cell that is S-layer deficient. [1].



[]

Culture

Bacteria identified from culture of a dog with a periodontal disease. T. forsythia comprises 20% of the bacteria identified. [2].

Periodontal Diseases in Canines

Image of a dog with severe plaque and calculus buildup [3].


[]

S-layer and BspA

Abscesses

Image of a severely infected abscess. Swelling has begun, along with redness surrounding the injury. [4].
