Prevention and treatment of fox disease: Fox omphalitis

Fox omphalitis is an acute viral disease characterized by damage to the central nervous system, increased excitability and epileptic seizures in foxes.

1. The original pathogen of the disease is fox adenosis, also known as fox omphalitis virus. Strong virus resistance, acid and ether resistance, 70% alcohol treatment. Disinfectants such as 4% Lysol, 2% sodium hydroxide and 20% bleach can kill. The fox adenovirus isolated in China is basically the same as canine infectious hepatitis virus and can agglutinate type O erythrocytes of guinea pig, chicken and human under the condition of 4 ℃.

2. Epidemic characteristics under natural conditions, 8-10-month-old young foxes are susceptible, and the case fatality rate is 10% to 20%. The disease can be infected through digestive tract and respiratory tract. Local epidemic is one of the characteristics of the disease. Young foxes often occur in contaminated farms for many years, generally in summer and autumn (July-October). The prolongation of epidemic period and contact infection to a certain extent are another characteristics of the disease.

3. The incubation period of clinical symptoms is 6-7 days, elevated body temperature, runny nose, diarrhea, eye knot tremor. Then excited, muscle spasmodic contraction, particularly sensitive to stimuli. Later ataxia, mental depression, dullness, hemiplegia or paraplegia, the course of about 2-3 days, mostly ended in death. When the disease is chronic, it causes miscarriage and dystocia of the female fox, and the young fox dies in the first few days after delivery.

4. Anatomical pathological changes of cerebral parenchyma, meninges and cerebrospinal cord hemorrhage, endocardial, pleural, pancreas and lung bleeding, hepatomegaly? ?

5. Diagnosis depends on pathogen examination, isolation and identification, as well as serological tests.

6. Prevention (1) Prevention: strengthen hygiene and epidemic prevention and disinfect regularly. The sick animals are quarantined in time. When introduced from abroad, customs quarantine must be strengthened and quarantined for one month before it can be shipped back without disease. (2) treatment: there is no effective treatment at present. You can try traditional Chinese medicine such as Shuanghua, Forsythia suspensa, Radix Isatidis, Folium Isatidis and so on. Take 5 grams of each fox internally, twice a day for 3 to 5 days.
