 Psoropitc mange is the disease caused by the '''non-burrowing''' mite, ''[[Psoroptes ovis]] ''(common name Scab mite), which affects sheep.
-Other species of Psoroptes mite affect a variety of species including Cattle, Goats, Horse, Rabbit, Camelid, however, all mites are host specific.

-The mite is active in the keratin layer of the skin and has abrasive mouthparts. It&nbsp;feeds on exudate of lymph, skin cells and bacteria caused by a hypersensitivity reaction to antigenic mite faeces,&nbsp;by the host. This causes '''intense&nbsp;pruritus''', leading to self trauma, crust and scale formation and inflammation.
