Popis: | African swine fever (ASF) is a highly lethal and contagious viral haemorrhagic disease of domestic and wild pigs, caused by the ASF virus (ASFV). After entering China in 2018, the disease has continued to spread through Asia. In September 2019, a team from the Indonesian Research Center for Veterinary Science, Bogor, investigated outbreaks in backyard pigs in the Dairi and Humbang Hasundutan districts of North Sumatra province. In January 2020, three pigs purchased from a pig seller in Bogor District, West Java province were also tested. Real-time PCR results confirmed ASFV DNA in sixteen out of twenty-nine samples, with nine positive samples from North Sumatra and seven from West Java. Four partial or full-length genes (i.e. p72, p54, pB602L and CD2v) and a 356-bp fragment between the I73R and I329L genes were sequenced from representative samples. Phylogenetic analysis established that the ASFV in the samples from both North Sumatra and West Java were identical, indicating a common source of infection, and that they belonged to the p72 genotype II and serogroup 8. The sequences from the Indonesian ASFVs were also identical to other genotype II ASFV from domestic pigs in Vietnam, China and Russia. |
