Abstract
ABSTRACT: Sheep psoroptic mange is a form of highly itchy and contagious dermatitis caused by the mite Psoroptes ovis. Here, we reporteda case of sheep psoroptic mange outbreak at a property in São Vicente do Sul, Rio Grande do Sul (RS), Brazil. Poor nutritional status, restless behavior, pruritus, wool fall, yellowish crusted skin lesions with edge exudate, erythema surrounding the lesions and presence of wool trapped between the teeth were observed in the herd. Complete blood count test showed marked eosinophilia, and parasitological examination of a skin scrape revealed P. ovis. Histopathological examination of a skin biopsy sample revealed eosinophilic pustular dermatitis. The treatment consisted of two administrations of 1% ivermectin at 1 mL/33 kg of body weight subcutaneously over an interval of 10 days. To the best of our knowledge, this is the first report of the occurrence of psoroptic mange at a sheep farm of RS with description of the clinical signs and laboratory and histopathological findings.
