Ahman SE, Bergstrom KE. Cutaneous carriage of Malassezia species in healthy and seborrhoeic Sphynx cats and a comparison to carriage in Devon Rex cats. J Feline Med Surg. Dec 2009;11(12):970-976.
This study looked at the presence of Malassesia species yeast in 32 Sphynx cats and in ten domestic shorthair cats (DSH). Cutaneous colonization of large numbers of Malassezia species of yeast may be related to endocrine, immunosuppressive, neoplastic, or allergic skin disease in cats. Devon Rex cats were recently shown to carry significantly more Malassezia species on their skin than did healthy DSH cats, and they were also predisposed to Massezia-associated seborrheic dermatitis. The Sphynx is an almost hairless cat breed and the Devon Rex was used for many years to outcross Sphynx. Seven sites on the body of each cat were tested. Malassezia species were isolated from 26/32 Sphynx cats (81%) and from 0/10 DSH control cats. All seborrheic cats had M. pachydermatitis isolated from their skin, at multiple sites. None of the 32 Sphynx had Malassezia species isolated from the ears. Based on the location and number of yeast isolates, in Sphynx and Devon Rex, the axilla, groin, and claw fold might be more representative sites for yeast recovery and clinical significance than sampling from the ears.
