Abstract

An adult female free-ranging American black bear (Ursus americanus) was presented in poor body condition, with advanced skin disease. Skin changes included hair loss, lichenification, crusting, and focal erosions. Skin scrapings and histopathology identified two distinct parasitic conditions that were contributing to this animal's dermatitis. Large numbers of larvae, nymphs, and adults of Sarcoptes scabiei were present in the superficial epidermis, and nematodes consistent with Pelodera strongyloides were abundant within the hair follicles. This appears to be the first reported case of Pelodera dermatitis in a bear species, adding a new differential agent to the list for dermatitis in bears. The sarcoptic mange and poor body condition of this bear may have been contributing factors to the development of the opportunistic Pelodera infestation.
