In the U.K., where sheep scab is endemic, neither the disease nor the mites appear to be transmitted from sheep to cattle or goats. Geographic Distribution Sheep scab has been eradicated from Australia, New Zealand, Scandinavia, the U.S. and Canada, but it can still be found in many other countries.
Etiology Sheep scab is caused by Psoroptes ovis, a mite (arthropod) in the family Psoroptidae (Order Astigmata). Psoroptes mites have traditionally been separated into species based on their host and body site preferences, and the morphology of the male mites.
