ABSTRACT
In a random sample of 30,444 larynges from slaughtered beef cattle, 441 (1.4%) had chronic diphtheria and 1,345 (4.4%) had papillomatosis. Both types of lesions were centered in mucous membranes over the vocal processes and medial angles of the arytenoid cartilages. Since they are found in the same anatomical locations as laryngeal contact ulcers, we hypothesize that ulcers are primary and diphtheria and papillomatosis are secondary.
