Biology, diagnosis and management of sarcoptic mange

Scabies (also known as sarcoptic mange) is a common, highly contagious skin disease in animals and humans. It is caused by the ectoparasitic burrowing mite Sarcoptes scabiei (family: Sarcoptidae), which has a worldwide distribution. Animals and humans can be infested by their own S. scabiei subtype; however crossspecies transmission may occur. The socioeconomic and public health importance of scabies is significant. The disease occurs when the mite burrows into the skin and feeds on host epidermis. Disease manifestations are mediated via inflammatory and allergic responses to mite products, which result in severely pruritic lesions. Early diagnosis and prompt treatment is essential to minimise the spread of infestation. Veterinary nurses have a vital role to play in early recognition, diagnosis and for providing owners with accurate accessible advice to prevent zoonotic transmission. This article summarises the latest data on the biology, diagnosis and control of scabies.
