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.
