The expressions of viral structural proteins by ASFVs of different passages. The PAMs of domestic pigs were infected with ASFV YZ-1, ASFV YZ-2 and ASFV YZ-3 of different passages (P1, P2, P3, P4 and P5) at a MOI (multiplicity of infection) of 0.1 for 72–96 h. The infected cells were harvested and subjected for detection of the viral p30, p54, p72 and p17 protein expressions by Western blotting. Lane 1, mock infection controls; lane 2, infection with normal tissues; lanes 3–7, infections with ASFV P1, P2, P3, P4 and P5, respectively
