===Pathology===

In acute calssical swine fever, pathological changes are most typically haemorrhagic. Haemorrhages are seen in the lymph nodes, which are also swollen and oedematous. Appearance of haemorrhages in the kidney can vary from petechiae (giving a "turkey egg" kidney) to ecchymoses, and petechiae can also be observed in the larynx, bladder and heart as well as on serosal surfaced. A non-purulent encephalitis is sometimes seen.

In acute classical swine fever, the major pathological change is multiple haemorrhages. This is seen as many purple blotches in the skin, and as sub-capsular bleeding in association with swelling and oedema in all lymph nodes. A "turkey egg" appearance to the kidneys is displayed, with haemorrhage varying from petechiae to ecchymoses.  and petechiae can also be observed in the larynx, bladder and heart as well as on serosal surfaced. A non-purulent encephalitis is sometimes seen.
