The present study was undertaken to find out lesions/affections in brains of 33 adult cattle, 35 adult buffaloes and 18 calves (6 cattle, 12 buffalo), since the information on the same is very scanty. Gross examination of brains did not show any specific lesions. On microscopic examination, 15/33 (45.45%) cattle, 20/35 (57.14%) buffaloes and 11/12 (91.66%) buffalo calves showed: chromatolysis (3 cattle,1 buffalo and 2 buffalo calves), neuronal degeneration (6 cattle, 12 buffaloes and 11 buffalo calves), vascular congestion (15 cattle, 17 buffaloes and 1 buffalo calf), hemorrhages (11 cattle, 2 buffaloes and 2 buffalo calves), edema around vessels (1 cattle), proteinous globules in vessels (1 cattle and 3 buffaloes), neuronophagia (1 buffalo), satellitosis (1 cattle and 1 buffalo), subependymal gliosis (lcatüe), perivascular cuffing (2 cattle and 2 buffaloes), microgliosis (1 cattle, 1 buffalo and 1 buffalo calf), and pineal gland calcification (9/35 (25.71%) buffaloes). The above lesions were found distributed in different neuroanotomical sites, either singly or in combination.
