Actinobacillus

Actinobacillosis is a zoonotic disease caused by Actinobacillus.

It is more commonly associated with animals than with humans.

One of the most commons form for veterinarians is the mouth actinobacillosis of cattle, due to Actinobacillus lignieresii. The most prominent symptom is the swelling of the tongue that comes out of the mouth and is very hard at palpation (wooden tongue).

Differential diagnosis
Mouth actinobacillosis of cattle must be differentiated from actinomycosis in animals that affects bone tissues of the maxilla.
