===Papular===

====Orf====

−

*[[Poxviridae|Pox]] infection

−

*Quite a common '''zoonotic''' disease

−

~~Papular proliferative pathology~~

−

~~=====Clinical=====~~

−

*In sheep produces a proliferative nodule/papular mass on [[Lips - Anatomy & Physiology|lips]]

−

*In flocks in which it is endemic it is seen in lamb

−

*If flock is non-immune seen in ewes too but much worse in lambs (may spread to inside of mouth)

−

*Can spread to udder of ewe

−

~~=====Pathology=====~~

−

*Poxvirus infections produce local infection of [[prickle cells]] in epithelium with proliferation of cells and formation of papule followed by ulceration / necrosis and covered by necrotic epithelium

−

*Eventually scabs form and crust drops off

−

*Scabs - very infectious ( N.B.if touch -> catch it)
