Prevention and treatment of deer disease: deer mucosal disease
Deer mucosal disease is a disease caused by mucosal virus, which is characterized by acute, catarrhal inflammation of gastrointestinal and upper respiratory mucosa.
1. The original pathogen of the disease is mucosal disease virus, also known as bovine viral diarrhea virus. The virus was sensitive to ether, chloroform and acid, and was inactivated quickly at 56 ℃.
2. Epidemic characteristics the sources of infection are diseased deer and infected deer. The virus is excreted from the body with nose and eye secretions, milk, feces, urine and semen, and ingestion or inhalation of contaminated substances is the main mode of transmission. Deer, musk and many kinds of ruminants are susceptible. The disease can occur all the year round, but it is more common in late winter and early spring.
3. The clinical symptoms of artificial infection of deer are consistent with those of natural disease, showing weakness, obvious decline of hearing and vision, dehydration and emaciation. Some sick deer have a lot of tears and corneal opacity. Feces contain a lot of mucus and blood.
4. anatomical and pathological changes abomasum and intestinal mucosal erosion, trachea, lung, abomasum and intestinal catarrhal or hemorrhagic inflammation, cystitis, glomerulonephritis, liver necrosis, ocular conjunctiva, nasal mucosa, oral mucosa petechial or ecchymosis bleeding. In some cases, there was blood in the skin, the bottom of the rumen and the epicardium. 5. Preliminary diagnosis can be made according to symptoms and pathological changes, and virus isolation and serological examination should be carried out for diagnosis.
6. There is no effective treatment for prevention and treatment at present. The affected deer should be isolated, nursing should be strengthened and symptomatic treatment should be carried out. The contaminated group can be vaccinated or urgently vaccinated with attenuated vaccine.
