===Clinical Signs===

In acute cases, key clinical findings are vomiting, abdominal pain, anorexia, diarrhoea and pyrexia. Signs of a bleeding disorder can be present in some cases. Clinical examination may reveal a combination of many features. These could include: lymphadenopathy, pharyngitis or tonsilar enlargement, pneumonia, abdominal distension and/or pain, hepatomegaly, jaundice, petechial or ecchymotic haemorrhages, epistaxis, bleeding from venipuncture sites or CNS signs such as depression, disorientation and seizures. Clinical signs tend to pesrsist for five to seven days before improvement is noted. During the recovery phase, 20% of cases develop corneal oedema and anterior uveitis ("blue eye").

Signs may be peracute or acute in onset. In acute cases, the key clinical findings are vomiting, abdominal pain, anorexia, diarrhoea and pyrexia. Some cases may also show signs of a bleeding disorder. However, there are many different features that clinical examination could possibly reveal. These might include:

 

* Abdominal distension and/or pain

* Petechial or ecchymotic haemorrhages

* Bleeding from venipuncture sites

 

* Pharyngitis or tonsilar enlargement

* CNS signs such as depression, disorientation and seizures.  

Clinical signs generally persist for five to seven days before the animal's condition improves. During the recovery phase, 20% of cases develop corneal oedema and anterior uveitis ("blue eye").

In peracute cases, death rapidly follows the onset of clinical signs.

In peracute cases, death rapidly follows the onset of clinical signs.
