Prognosis and treatment

The prognosis is favorable for cases of actinobacillosis treated early, but the lack of a definitive diagnosis makes the prognosis reserved. Treatment must be early; it is typically done by combining:

-An anti-infective which can be a sulfonamide, a penicillin, a tetracycline

- An iodine intake either intravenously (sodium iodide, possibly repeated 2 times at 2-week intervals) or orally (potassium iodide, 7-10g/day for 7 to 10 days). Signs of iodism (watering eyes, skin releasing scales, cough, etc.) may occur.

Prevention

Isolate the sick

-Disinfect infected areas (troughs, etc.)

-Avoid contact with food that is irritating to the mouth.
