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

boars.

The clinical sign and necropsy of the wild

boars infected by Russian isolate of virus

ASF, has shown what wild boars is very

susceptible to African swine fever virus.
