| + | Pathological changes visible on post mortem examination |
| + | are observed most often in lymph nodes, |
| + | 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). |
