基因缺失的减毒非洲猪瘟病毒及其作为疫苗的应用
摘要：
本发明涉及可作为疫苗的基因缺失减毒非洲猪瘟病毒及疫苗以及构建方法。本发明采用非洲猪瘟中国流行株Pig/CN/HLJ/2018，经基因工程技术，将非洲猪瘟病毒的毒力基因缺失，获得MGF360-505R缺失和CD2V与MGF360-505R联合缺失的基因缺失病毒。经实验表明所述两种毒株均能提供对非洲猪瘟中国流行强毒株的100％免疫保护，可作为安全和有效的防控中国非洲猪瘟疫情的疫苗，具有极大的社会价值。
摘要（英）：

The invention relates to a gene deletion attenuated African swine fever virus as a vaccine and the vaccine, and a construction method thereof. An African swine fever Chinese epidemic strain Pig/CN/HLJ/2018 is adopted, a virulence gene of the African swine fever virus is deleted by a genetic engineering technology, and the gene deletion virus of MGF360-505R deletion and joint deletion of CD2V and MGF360-505R is obtained. Experiments show that the two virus strains can provide 100% immune protection against the African swine fever Chinese epidemic virulent strains, can be used as vaccines for safe and effective prevention and control of African swine fever in China, and have great social value.
