Histopathologic examination of the brain tissue in lambs with neurological symptoms: Enzootic ataxia

The aim of this study was to retrospectively evaluate the pathomorphological findings detected in the brains of lambs which died and were reported to have shown neurological symptoms in clinical anamnesis. Macroscopically, gelatinous softening and cavities were observed in the cortex. Brain tissue sections were stained with hematoxylin and eosin (HE). Multifocal gliosis was observed in six cases, calcification of neurons in four, of which one case was severe, and demyelination in four, of which three had gitter cells. The lambs showed neurological symptoms, such as brain lesions of different characteristics and severity, on histopathological examination before death and were diagnosed with enzootic ataxia
