Neutrophilic inflammation
* Opportunistic pathogens take advantage of acidotic lesions and other disturbances of rumen flora.
** e.g. ''F. necrophorum'', fungi
** Infection with ''Mucor'' gives [[Mucormycosis|mucormycosis]]- chronic ongoing granulomatous rumenitis.
** Also agents which cause lesions in other areas of tract e.g. BVDV, actinobacillosis.
====Pathology====
=====Gross=====
* Multiple, dark red areas of swollen papillae, mainly in ventral sac and pillars.
=====Histological=====
* Coagulative necrosis of papillae
* Marked neutrophil infiltrate
* Serofibrinous exudate
* Thromboembolic spread to form areas of coagulative necrosis and abscesses in [[Liver - Anatomy & Physiology|liver]].[[Category:Forestomach_-_Inflammatory_Pathology]][[Category:Cattle]]
