The cytopathic effects (CPEs) caused by three ASFV isolates. The PAMs of Bama minipigs were infected with the spleen tissue homogenates of three pigs (ASFV YZ-1, YZ-2 and YZ-3). At 72–96 h post infections, ASFV CPEs were observed under microscopy. The PAMs of domestic pigs had identical CPEs with infections of three ASFV isolates. The scale bar is 200 μM
