While actinomycosis is an infectious disease it does not seem to be transmitted directly from one animal to another. Numer- ous investigators have tried to produce it by inoculating cattle, calves, sheep, goats, pigs, dogs, cats, rabbits and guinea pigs with actinomyco- tic lesions. The results have almost invariably been negative when pus was used, but the disease has developed after inoculating cattle with pieces of tissue containing the organism in its vegetating state. The supposition is that the parasite gains entrance to the living tissues through slight wounds of the mucous membrane of the mouth or throat and perhaps the alveoh of diseased teeth or during the shed-.
