Clinical and hematological aspects and enzooticz bladder lesions in chronic spontaneous poisoning by Pteridium aquilinum in cattle. Gabriel I ; Glaucia D. Masuda I ; Rafael A. Barros II ; Tessie B. Spontaneous cases of chronic poisoning by Pteridium aquilinum in cattle were studied. Clinical signs and blood work were evaluated at terminal phase of disease.


In cattle with BEH, hematuria was observed in all cases, followed by progressive weight loss. Non-regenerative anemia was detected in Changes in white blood count occurred in some cases but drop in lymphocyte numbers was uncommon in both forms of disease.

In BEH form, the bladder had nodules, large neoplastic masses, red urine, papilomas, and hemorrhages. Pyelonephritis and hydronephrosis were seen in a few cases. In BEH, mesenchymal neoplasms were more observed than epithelial ones, and most of them were malignant.

Immunohistochemistry was utilized to characterize the histogenesis of poorly differentiated neoplasms. In conclusion, the morphological study demonstrated that urinary bladder lesions boviina to the those seen in cattle with BEH, are very often present in cattle with the UDT SCCs form.


Diseases of cattle, poisonous plants; Pteridium aquilinum, bovine enzootic hematuria, squamous cell carcinomas of the digestive system, veterinary pathology. Foi realizada a necropsia e os materiais coletados. Bexigas normais de 10 bovinos foram utilizadas como controles. Concomitantemente ao desvio a esquerda, um bovino apresentou linfopenia, outro eosinofilia, e um outro monocitose. Talvez esse tipo de anemia possa explicar os resultados aqui obtidos.

Em enzotoica dois bovinos com HEB observou-se linfopenia, sendo este um achado importante em bovinos de um estudo experimental Campo et al.
