Hyperplasia and serohemorrhagic lymphadenitis of
submandibular lymph nodes
Serous exudate impure of blood in the
thoracic cavity
Serohemorrhagic lymphadenitis of mesenterial lymph nodes
A greatly enlarged (hyperplasia) dark red to black spleen
Enlarged dark red renal lymph nodes, petechial
hemorrhages in the renal cortex
Congestive hyperemia and edema of the lung
Very enlarged dark red (hemorrhagic)
gastrohepatic lymph nodes
ASF is highly contagious disease not only
for domestic swine, but and for the wild

The clinical sign and necropsy of the wild
boars infected by Russian isolate of virus
