Cheyletiella dermatitis. A mite infestation of rabbit, cat, dog, and man

Abstract

Two patients with recurrent, intensely pruritic, grouped red papules on the chest, abdomen, and thighs were examined and found to have Cheyletiella dermatitis. Cheyletiella, a nonburrowing species of mite, was isolated from fur brushings of the household pets, including one dog and two cats. Treatment of the affected pets resulted in complete resolution of symptoms and signs in both animals and patients. This appears to be the third instance of human Cheyletiella dermatitis recorded in North America.
