Pathological changes visible on post mortem examination

 

are observed most often in lymph nodes,

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.

spleen and kidneys. The lymph nodes become swollen,

oedematous and haemorrhagic (Fig. 2). Haemorrhages

of the kidney may vary in size from petechiae

to ecchymotic haemorrhages. Petechiae can also be

observed in the urinary bladder, larynx, epiglottis and

heart, and may be widespread over the serosae of the

abdomen and chest. A non-purulent encephalitis is

often present (Gruber et al., 1995).
