Malassezia Dermatitis – Diagnosis and Management

Malassezia dermatitis is one of the more common causes of pruritus and dermatitis in dogs with, or without, allergic skin disease. A number of factors contribute to colonisation by Malassezia and subsequent skin disease. Furthermore in some individuals Malassezia can trigger hypersensitivity and/or cell-mediated immune responses.

Diagnosis is generally based on clinical signs, cytological findings, and culture, and, in some cases, response to treatment. Topical treatment is the mainstay of management as many cases require lifelong therapy. Systemic treatment may be used in non-responsive cases, or where better compliance is required.
