(b) Vesicular stomatitis of the dental pad of infected calf characterized by leukocytic infiltrations of mucosal and submucosal layer of cornified epithelial tissue (arrows), H&E, X200. (c) Zenker,s necrosis (arrows) of muscular layers of stratified squamus epithelim with edema inbetween (arrowheads) of cattle, H&E, X200. (d) Mild myocarditis of the myocardium of buffalo with mild lymphocytic cell aggregations (arrows), H&E, X400. (e) Moderate myocarditis of the myocardium of buffalo calf (less than 2 Y) with moderate lymphocytic cell aggregations (arrows) and mild myocardial muscle necrosis (arrowheads), H&E, X400. (f) Severe non- suppurative myocarditis of heart of calf with a significant number of lymphocytic cell aggregations (arrows) with complete lysis of necrosed muscle fibers (arrowheads) and replacement of this muscles by a large number of inflammatory cells (arrows). The black star, referring to the myocardial muscle that still normal not necrosed, H&E, X400.</p
