Abstract: A skin disease was studied in 159 sheep on 15 farms located in seven counties of northeastern and southeastern of the state of Pará and in one farm in the state of Roraima, Brazil. The disease affected mainly two to four year-old sheep of the Santa Ines breed and crossbreds. Clinical signs were characterized by alopecia, multifocal erythema, small papules, and crusts in several areas of the body, mainly around the eyes. Severe itching in the affected areas, restless, weight loss and lacrimation were also observed. Insects were always seen around the animals. Insects apparently associated with the lesions were captured and identified as pertaining to the genera Simulium and Hippelates. Biopsies of the skin lesions of 10 sheep revealed inflammatory non suppurative mononuclear infiltrates of the dermis with presence of eosinophils. The epidemiologic, clinical and pathological studies of the cases allowed the diagnosis of allergic dermatitis due to the insect bites.
