The disease mainly occurs in Africa, but also occurs in Europe, Asia and In other areas, various ruminants such as buffaloes, dairy cows and yellow cattle are susceptible, and they are listed as the second category in my country's "List of Types I, II, and III Animal Diseases" animal disease. Among at least 10 herpes viruses associated with ruminants, the pathogenic pathogens that can cause malignant catarrhal fever are respectively 1, AlHV-1), in fact, almost all clinical cases of malignant catarrhal fever in cattle are caused by virus infection carried by sheep and wildebeest. In areas where there are no wild animals such as wildebeest, domestic sheep can also be infected with the disease, and most of them are recessive infections without clinical symptoms, which has become Major source of infection in cattle. The main features of sick cattle are short-term high fever, high degree of inflammation in the mucous membranes of the mouth, nose and eyes, and even bleeding and Ulcers, neurological symptoms can be seen in the early stage, and the acute fatality rate is very high. The clinical symptoms of bovine malignant catarrhal fever are easily related to bovine viral diarrhea/mucosal disease, oral Confused with hoof disease, bovine infectious rhinotracheitis, rinderpest, bluetongue, and vesicular stomatitis; when accompanied by severe neurological symptoms, with rabies, tick-transmitted The clinical symptoms of acute encephalitis are relatively similar, and laboratory differential diagnosis is required. This document refers to the relevant content of the "Manual of Terrestrial Animal Diagnostic Reagents and Vaccines" (OIE), and the technical methods are consistent with the standards recommended by OIE. same method. Among them, the pathogen isolation method is applicable to the swollen surface lymph nodes of living animals, peripheral blood and dead animals. MCFV nucleic acid can be used to detect proviral DNA; indirect immunofluorescence antibody test, enzyme-linked immunosorbent assay (Enzyme- Epidemiological investigation, inspection and quarantine.

Cattle and buffalo are susceptible among all susceptible animals Strong sex, especially young and middle-aged cattle aged 1 to 4 are prone to the disease, and elderly cattle are less likely to develop the disease. Mild or recessive infection in a small number of cattle situation, and continued to carry the virus. 4.1.2 Wildebeest, wildebeest, antelope and other wild animals and blood-sucking insects are the main sources of infection of this disease; In the region, the sheep with recessive infection is the main source of infection of the disease, and the affected cattle often have a history of contact with sheep, such as grazing in groups or feeding in the same pen. Raise and so on. 4.1.3 Bovine malignant catarrhal virus mainly exists in the blood, brain, spleen, lymph nodes and other tissues of sick cattle, and can be mechanically transmitted by blood-sucking insects. transmission; the virus can also be transmitted through the placenta. The incubation period is generally 10d~34d. 4.2 Clinical symptoms 4.2.1 Head-eye type The head-eye type is the most common disease type, with a higher mortality rate. At the beginning of the disease, the body temperature rises above 40°C, the appetite and rumination decrease, and the skin on the head develops hot. Symptoms often appear in the eyes, mouth, and nasal mucosa on the second day of the onset, and the conjunctiva of both eyes is severely inflamed, and yellowish-brown purulent and fibrinous secretions flow out. eyelid swelling, corneal opacity, severe superficial ulceration, and even corneal perforation. The course of the disease is mostly 1 week to 2 weeks, with the course of the disease The diseased cattle were severely weakened and died of exhaustion. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 42115-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 42115-2022_English as soon as possible, and keep you informed of the progress.
