One handred brain samples were obtained randomly from Mosul animal slaughter house and butcher shops since October 2012 to August 2013 from animals with and without nervous signs. The main gross lesions were edema which accounted 53% of the cases, congestion 51% , hemorrhage 20% and 3% cyst of coenurous cerebralis. The major lesions were observed by histopathological examination of three different areas of the brain (cerebrum, cerebellum and medulla oblongata)in each case.
