MACEDO, Juliana T.S.A.; RIET-CORREA, Franklin; DANTAS, Antônio Flávio Medeiros  and  SIMOES, Sara Vilar Dantas. Diseases of the skin in sheep and goats from the Brazilian semiarid. Pesq. Vet. Bras. [online]. 2008, vol.28, n.12, pp.633-642. ISSN 0100-736X.

A study of the skin diseases in sheep and goats in the semiarid of the states of Paraíba, Pernambuco and Rio Grande do Norte, Northeastern Brazil was performed. From January 2000 to November 2006, 656 cases in goats and 324 in sheep were presented to the Veterinary Hospital of the Federal University of Campina Grande in Patos, Paraíba. Additionally mailed in biopsy or necropsy skin samples from 31 goats and 45 sheep were studied histologically. Skin diseases were diagnosed in 35 goats (5.33% of all cases in this species) and 45 sheep (13.88% of the cases in this species). The most frequent skin disease was myiasis (10 cases in goats and 7 in sheep), followed by contagious echtyma (8 cases in goats and 2 in sheep), squamous cell carcinoma (4 cases in goats and 5 in sheep), dermatophylosis (8 cases in sheep), and allergic dermatitis (1 case in goats and 1 in sheep). Two cases of pythiosis in sheep, two cases of epidermolysis bullosa in goats, one case of poisoning by Brachiaria brizantha (photosensitization) and another by Leucaena leucocephala (alopecia) in sheep, and one case of papillomatosis, one of pemphigus foliaceous, one of protothecosis and one of rhabdomyosarcoma in goats were also diagnosed. In 4 cases in sheep and 19 in goats the etiologic diagnosis was not obtained. With the information of the occurrence and epidemiology of the skin diseases is possible to determine efficient control measures.
