actinomycosis defined in 1939 yearactinomycosis - Actinomycosis (Gr. aktis, ray; mykes, fungus);
actinomycosis - Disease in cattle, occurring rarely in the horse, and sometimes in sheep, pigs, and dogs. Human beings occasionally sufler from it. In cattle it is commonly known by the name of wooden tongue, because it usually attacks that organ, producing a hard growth. The disease is due to a parasite known as the ray fungus, which enters the animal by means of some foodstuff, especially barley, on which the fungus grows. This makes its way into the animal's tissues through some abrasion in the mucous membrane or through a bad tooth, and thus irritates the tissues and produces a tumour which is followed by suppuration and ulceration. See Bacteriology.
