Abstract

On 7 March 2019, African swine fever in a domestic pig farm was detected in Guangxi Province of China. The phylogenetic analysis showed that its causative strain contained two tandem repeat sequence insertions in the intergenic region between the I73R and the I329L genes, and was different from previously reported strains in China and other countries.
