[2] One of the most common forms seen by veterinarians is mouth actinobacillosis of cattle, due to Actinobacillus lignieresii.
Actinobacillus suis is an important disease of pigs of all ages and can lead to severe morbidity and sudden death.
[3] The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters.
When only the mouth is involved, actinobacillosis in cattle and other ruminants can frequently be treated with intravenous administration of sodium iodide.
In more severe cases, or instances in which the animal either does not respond to sodium iodide or begins to develop signs of toxicity to it, antibiotics may be used instead.
