Resumo: | ABSTRACT: It is reported the occurrence of enzootic hematuria (EH) in buffaloes in Brazil after performing an epidemiological survey and clinicopathological analises. To date, EH caused by ingestion of Pteridium esculentum subsp. arachnoideum, a radiomimetic plant popularly known as “bracken fern”, has not been described in this species in Brazil. Bovine EH is responsible for high economic losses in Brazil’s Southeast Region not only because of the deaths it causes, but also owing to its negative effect on productivity. In São José do Barreiro County, São Paulo, some farmers in areas with a high incidence of bovine EH have been replacing cattle with buffaloes, based on the premise that the latter would be more resistant to poisoning by ingestion of Pteridium spp. However, even though initial observations indicated that buffaloes are indeed less sensitive than cattle to the toxic principle of Pteridium spp., cases of hematuria in this species have been reported. According to preliminary date, EH only occurs in buffaloes over six years of age. Macroscopic examination revealed a thickened urinary vesicle mucosa, along with multiple foci of ulcerated, exophytic, verrucous, and pedunculated lesions. In one of the buffaloes studied, the bladder wall was ruptured and exhibited marked secondary inflammation. Histologically, neoplastic and non-neoplastic changes similar to those described in cattle poisoned by Pteridium spp. were observed. The neoplasms found included papilloma, carcinoma in situ, urothelial carcinoma (low and high grade), inverted, microcystic, and trabecular variants, urothelial carcinoma with divergent differentiation (squamous and glandular), squamous cell carcinoma, lymphangioma, hemangioma, and hemangiosarcoma. There was also coexistence of epithelial and mesenchymal neoplasms. Bovine papillomavirus particles were not detected by polymerase chain reaction in the bladder samples analyzed. |
