Bovine Progressive Degenerative Myeloencephalopathy (Weaver Syndrome) in Brown Swiss Cattle in Canada: A Literature Review and Case Report

摘要

A 15-month-old purebred Brown Swiss heifer was presented because of posterior paresis and ataxia. Histopathological examination of the brain and spinal cord showed evidence of a mild diffuse degenerative myeloencephalopathy. The most severe degenerative lesions were located in the white matter of the thoracic spinal cord. We believe this to be the first documented case of bovine progressive degenerative myeloencephalopathy (“weaver syndrome”) in Canada.
