*''[[Fusobacterium necrophorum]]''
*calves and lambs
*common in intensively reared beef cattle
*occurs following an infected umbilicus in neonates and from rumenitis in adult cattle
=====Gross=====
*rounded pale multiple foci of coagulative necrosis throughout the [[Liver - Anatomy & Physiology|liver]]
*unsoftened, greyish-yellow patches
*ringed by a zone of hyperaemia
*foci coalesce in severe cases
*in adult animals, these lesions may have progressed to abscesses following lysis of the coagulated necrotic tissue and the formation of fibrous capsule around the damaged tissue
*if animal survives, these lesions may soften develop into abscesses
=====Microscopically=====
*coagulative necrosis
*possible evidence of migrating flukes
*bacteria can be demonstrated in the periphery of the necrotic tissue, especially near its junction with viable tissue
*there is a rim of neutrophilic cells
