Abstract
African swine fever has caused substantial economic losses to China`s pig industry in recent years. Currently, the highly pathogenic African swine fever virus strain of genotype II is predominantly circulating in China, accompanied by a series of emerging isolates displaying unique genetic variations. The pathogenicity of these emerging strains is still unclear. Recently, a novel ASFV strain with a distinguishable three-large-fragment gene deletion was obtained from the field specimens, and its in vivo pathogenicity and transmission were evaluated in this study. The animal experiment involved inoculating a high dose of YNFN202103 and comparing its effects with those of the highly pathogenic strain GZ201801_2. Results showed that pigs infected by YNFN202103 exhibited significantly prolonged onset and survival time, lower viremia levels, and less severe histopathological lesions compared to GZ201801_2. These findings contributed valuable insights into the pathogenicity and transmission of ASFV and its prevention and eradication strategies in practical settings.
