This report describes the clinical signs, diagnosis, and therapy of de
modicosis in ferrets. Two ferrets (Mustela putorius furo) were present
ed with a history of local alopecia and pruritus after repeated treatm
ent with a glucocorticoid-containing ointment for recurrent ear mite i
nfections. Skin scrapings and biopsies revealed adult mites and larvae
of Demodex spp., which were measured according to current classificat
ion techniques. Treatment with amitraz was effective and did not cause
noticeable side effects. To the authors' knowledge this is the first
report of demodicosis in ferrets.
