| + | =====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===== |
| + | Papular proliferative 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) |
