==Clinical Signs==
Clinical signs are a rare feature of the disease and abscesses are frequently only observed as incidental findings at slaughter or post mortem. Detailed clinical examination may reveal signs of pyrexia, depression and weight loss. Evidence of abdominal pain may be present such as bruxism, grunting and abduction of the elbows. There may be a history of change in diet from pasture to a high-concentrate ration, as well as anorexia and reduced milk production. Clinical signs of caudal vena cava thrombosis may be apparent if abscesses have involved the posterior vena cava, including chronic diarrhoea, emaciation, ascites and distension of subcutaneous abdominal veins.

Rupture of hepatic abscesses is associated with anaphylactic shock and death. In these cases, the lungs appear markedly oedematous and collapsed at post mortem.
