Identification of two novel linear epitopes on the p30 protein of African swine fever virus

African swine fever(ASF)is a hemorrhagic disease caused by African swine fever virus(ASFV),which belongs to the Asfarviridae family.ASF has become prevalent in Africa since it was first reported in Kenya in 1921(Rowlands et al.2008;Costard et al.2009).In 1957,it was introduced to Portugal in Europe,after which ASFV rapidly spread to other European countries and has already been eradicated in several countries except Sardinia(Mur et al.2016).In 2007,ASF was introduced to Georgia and has continued its spread to other countries in Europe(Smietanka et al.2016;Kolbasov et al.2018;Garigliany et al.2019;Linden et al.2019).In China,an ASF outbreak was first reported on August 3,2018 in a pig farm in Shenyang,Liaoning Province(Zhou et al.2018).Since then,the dramatic spread of ASF throughout China has caused huge economic losses to the swine industry(Jiang et al.2021).
