Epidemiological data on Pteridium aquilinum intoxication in cattle the state of Santa Catarina were obtained by review of diagnostic records from 1987 to 2001. Of 3,407 necropsied cattle, 244 (7.16%) were diagnosed as intoxicated by Paquilinum; 122 of those were of the hemorrhagic form, 103 had tumors in the upper digestive tract, 19 were cases of chronic hematuria. Annual losses due to this intoxication in this State are estimated at 10,657 cattle. The highest incidence of the hemorrhagic form occurs in 1-3-y-old cattle between March and July, and most cases of tumors of the upper digestive tract affect cattle older than Sy. The highest incidence of digestive tract tumors is at the base of the tongue and pharynx, and the lowest frequency is in the rumen and esophagus. The large economic losses caused PaQuilinum in Santa Catarina call for improved control measures for the disease.
通过查阅1987年至2001年的诊断记录，获取了圣卡塔琳娜州牛类蕨中毒的流行病学数据。在3407头进行尸检的牛中，有244头（7.16%）被诊断为蕨中毒；其中122头为出血型，103头上消化道有肿瘤，19例为慢性血尿。该州因这种中毒造成的年损失估计为10657头牛。出血型的最高发病率出现在1至3岁的牛中，时间为3月至7月，而上消化道肿瘤的大多数病例影响5岁以上的牛。消化道肿瘤的最高发病率位于舌根和咽部，最低发病率在瘤胃和食管。蕨在圣卡塔琳娜州造成的巨大经济损失，需要改进该疾病的控制措施。
