Bovine enzootic haematuria (BEH) is caused by prolonged ingestion of toxic principles of bracken fern, essentially by Pteridium spp. In northwestern Argentina, this disease has a great economic impact ant it is attributed a chronic consumption to Pteridium arachnoideum. This paper describes two endemic areas for enzootic hematuria due to the consumption of Pteris deflexa and Pteris plumula. Two areas where P. deflexa and P. plumula are endemic, but free of Pteridium species, were devised and seven farms were visited. The disease was confirmed based on the presence of clinically affected animals. In four necropsies bleeding neoplastic lesions were observed in the mucosa of the urinary bladder. At phytochemical analysis, both ptaquiloside and pterosin B were found in P. deflexa and P. plumula. Thus, the consumption of P. deflexa and P. plumula can also cause BEH.
牛地方性血尿（BEH）是由于长期摄入蕨类植物的有毒成分所致，主要是蕨属植物。在阿根廷西北部，这种疾病造成了巨大的经济影响，并且人们认为该病是由长期食用蛛毛蕨引起的。本文描述了因食用镰羽蕨和密毛蕨而导致地方性血尿的两个流行地区。划定了两个镰羽蕨和密毛蕨为地方特有种但无蕨属物种的区域，并走访了七个农场。根据临床患病动物的存在情况确诊了该病。在四次尸检中，在膀胱黏膜中观察到出血性肿瘤病变。在植物化学分析中，在镰羽蕨和密毛蕨中均发现了ptaquiloside和pterosin B。因此，食用镰羽蕨和密毛蕨也可导致牛地方性血尿。
