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.
在对30444头屠宰肉牛的喉部进行随机抽样检查时，发现441头（1.4%）患有慢性白喉，1345头（4.4%）患有乳头状瘤病。这两种病变均集中在杓状软骨声带突及内侧角上方的黏膜处。由于它们与喉接触性溃疡处于相同的解剖位置，我们推测溃疡是原发性的，而白喉和乳头状瘤病是继发性的。
