title: THADEUA GREENI-ASSOCIATED DERMATITIS IN AN EASTERN BETTONG (BETTONGIA GAIMARDI).
abstract: An adult female bettong (Bettongia gaimardi) presented with extensive alopecia and dermatitis affecting the ventral and lateral aspects of the neck and thorax. Microscopic examination of skin scrapings collected from the affected area revealed large numbers of the dermanyssid mite Thadeua greeni. A histopathologic diagnosis of chronic proliferative and hyperkeratotic perivascular dermatitis with intralesional mites was returned. Treatment with a combination of topical fipronil and parenteral ivermectin weekly for 3 wk resulted in the resolution of clinical signs and apparent elimination of the mite.
