title: Notoedric acariasis in the porcupine (Erethizon dorsatum).
abstract: Six of 16 porcupines (Erethizon dorsatum) live-trapped in Sullivan County, Pennsylvania were infested with the mite Notoedres douglasi. Alopecia was evident in the ventral inguinal area and the infested skin was thickened, wrinkled and had multifocal areas of extensive hyperkeratosis. Microscopically the skin lesions consisted of extensive acanthosis and hyperkeratosis with variable cellular infiltrate in the dermis. Mites were seen in tunnels in the hyperkeratotic skin sections. This is the first report of notoedric acariasis in the porcupine.
