Spontaneous cases of chronic poisoning by Pteridium aquilinum in cattle were studied. RESULTS The changes found in the bladder of the animals were divided into neoplastic and hemtauria the last ones were subdivided into inflammatory, hyperplastic and metaplastic.

Regarding the incidence of the main neoplasms found in cattle with BEH in our study, it is not easy to make exact comparisons with the data found in the literature. Gabriel I ; Glaucia D.


Aetiology of enzootic haematuria. Due to the occurrence of two or more neoplasms in the same animal, differences in the methodology and in the concept of classification, a more precise comparison was not possible. Non-regenerative anemia was detected boina It is very likely that in human bladder tumors the variability is associated to the three embryonic segments that participate in the formation of the bladder, which are portions of the mesonephric ducts, the mesenchyma that surrounds the urogenital protuberance and the infra-umbilical portion of the abdominal wall Murphy et al.

Enzootiac the other hand, there is almost a perfect identity with the neoplastic processes that are found in the human bladder. On the other hand, diffuse lymphocytic infiltration and formation of lymphoid foci also occurred enzooica bladders without neoplastic processes.
