==Description==

'''Haemorrhagic gastroenteritis''' is characterised by acute [[Vomiting|vomiting]] and [[Diarrhoea|diarrhoea]].  Gastrointestinal integrity is loss, resulting in a rapid movement of blood, fluid and electrolytes into the intestinal lumen.  The aetiology is unknown but it may relate to ''[[:Category:Enteropathogenic and Enterotoxaemic Clostridia|Clostridium perfringens]]'' enterotoxicosis or an immune-mediated reaction.  There is usually no history of garbage, chemical or foreign body ingestion.

===Clinical Signs===

===Clinical Signs===

*Acute and progressive haematoemesis and/or haematochezia, with [[Vomiting|vomiting]] preceding [[Diarrhoea|diarrhoea]]

Include acute and progressive haematoemesis and/or haematochezia, with [[Vomiting|vomiting]] preceding [[Diarrhoea|diarrhoea]].

Other signs include depression, anorexia, abdominal pain, dehydration and  [[Shock#Hypovolaemic shock|hypovolaemic shock]] occurs over a period of 8 - 12 hours. Pyrexia can occur but is rare.

*Depression and anorexia

In severe cases patients may  be critically ill or moribund.

*Abdominal pain

*Dehydration and  [[Shock#Hypovolaemic shock|hypovolaemic shock]] occurs over a period of 8 - 12 hours.

*Pyrexia (rare)

*Thrombocytopaenia (severe cases)

*Pre-renal or renal azotaemia (severe cases)

 

===Laboratory Tests===

===Laboratory Tests===

*Haemoconcentration with PCV > 60%

*Haemoconcentration with PCV > 60%

*Normal or increased total protein concentrations, but proportionately lower than would be expected from the corresponding increase in PCV due to loss of protein through the intestines.
