An outbreak of combined Sarcoptes and Malassezia spp. infection was diagnosed in a rabbitry. About 20 (4%) of 500 rabbits were affected. Two 6- to 8-month-old female Holland Lops rabbits were submitted to the Tifton Diagnostic & Investigational Laboratory at The University of Georgia for complete necropsy. Gross lesions consisted of marked multifocal areas of alopecia, crusting, and dermatitis around the eye and on ears, nose, lips, neck, abdomen, feet, and external genitalia. Histologic examination of the skin revealed epidermal acanthosis with marked parakeratotic hyperkeratosis and cross sections of embedded mites consistent with Sarcoptes sp. and budding yeasts consistent with Malassezia sp. To the best of the author's knowledge, this is the first case report of combined Sarcoptes and Malassezia spp. infection in rabbits.
