Notoedric mange

A parasitic skin disease in cats

Notoedric mange is a highly contagious skin disease caused by the mite Notoedres cati. It primarily affects cats, but can also infest other animals and occasionally humans. This condition is characterized by intense itching, inflammation, and crusting of the skin.

Etiology

Notoedric mange is caused by the parasitic mite Notoedres cati. These mites are microscopic and burrow into the skin of the host, causing irritation and inflammation. The life cycle of the mite includes egg, larva, nymph, and adult stages, all of which occur on the host.

Transmission

The disease is highly contagious and is transmitted through direct contact with an infested animal. It can also spread via contaminated bedding or grooming tools. Although rare, humans can become temporary hosts, experiencing mild itching and rash.

Clinical Signs

The primary clinical sign of notoedric mange is intense pruritus (itching). Affected cats often have thickened, crusty skin, particularly around the ears, face, and neck. As the disease progresses, the lesions can spread to other parts of the body. Secondary bacterial infections are common due to scratching and skin damage.

Diagnosis

Diagnosis is typically made through skin scrapings examined under a microscope to identify the presence of Notoedres cati mites. Clinical signs and history of exposure to other infested animals can also aid in diagnosis.

Treatment

Treatment involves the use of acaricides to kill the mites. Topical treatments, such as lime sulfur dips or selamectin, are commonly used. In severe cases, systemic treatments like ivermectin may be prescribed. It is also important to treat all animals in the household and thoroughly clean the environment to prevent reinfestation.

Prevention

Preventing notoedric mange involves regular veterinary check-ups and maintaining good hygiene practices. Avoiding contact with infested animals and keeping living areas clean can help reduce the risk of transmission.

Prognosis

With appropriate treatment, the prognosis for cats with notoedric mange is generally good. Most cats recover fully, although severe cases may require prolonged treatment.
