Enzootic nasal adenocarcinoma is a fatal, malignant neoplastic, infectious disease in sheep and goats. It is caused by the Enzootic nasal tumor virus, a retrovirus similar to Jaagsiekte sheep retrovirus, which causes a similar disease, also in sheep and goats called Ovine pulmonary adenocarcinoma (OPA).[1] Symptoms include nasal discharge, dyspnea, facial deformity, and weight loss. Like OPA, the disease has a very long incubation period and is invariably fatal.[2]
