“…Therefore, identifying viral proteins that are important for in vitro and in vivo virus replication, and importantly in virus virulence in swine, is essential for the development of novel countermeasures to control the disease. Just a small number of genes have been successfully deleted from the ASFV genome, producing novel recombinant viruses (e.g., 9GL, UK, TK, MGF, NL, CD2, Lectin, DP148R, L83L, I177L, C962R, X69R) [ 3 , 4 , 5 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ] with a subset of deleted genes determined to be essential for virus replication (e.g. : EP152R, p30, p54, and p72) [ 17 , 18 , 19 , 20 ].…”
