Alopecia in a cow affected by Sarcoptes mange

Sarcoptes spp are a parasite of cattle which cause a skin disease known as Sarcoptic mange[1].

Sarcoptic mange is a contagious disease spread by direct contact or via fomites.

Species which have been reported as parasitic on cattle include:

  • Sarcoptes scabiei var bovis

Clinical signs include intense pruritus, alopecia and self-trauma. The whole body may be involved.

Diagnosis is made by deep skin scrapings, skin biopsy, or response to therapy[2]. Concurrent infections with Demodex spp has been reported[3]

Treatment relies primarily on insecticidal washes or topical drugs such as doramectin, ivermectin[4] or fipronil.

Sarcoptic mange is a zoonotic disease and caution must be exercised in limiting human contact with affected cattle[5].
