在随机抽取的30，444头屠宰肉牛的喉咙中，441头（1.4%）患有慢性白喉，1，345头（4.4%）患有乳头状瘤病。这两种类型的病变都集中在粘膜上的声带突起和内侧角的杓状软骨。由于它们与喉接触性溃疡位于相同的解剖位置，我们假设溃疡为原发性，白喉和乳头状瘤病为继发性。
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.
