| Asiatic cholera | <gastroenterology, microbiology> A form of infectious gastroenteritis (intestinal infection) that results in frequent watery stools, cramping abdominal pain and eventual collapse (from dehydration). Epidemic infections are seasonal in most third world countries, particularly Africa. (15 Jan 1998) |
| pancreatic cholera | Diarrhoea characterised by severe, watery, secretory diarrhoea and hyperkalaemia; most patients have hypercalcaemia, many have hyperglycaemia; results from excessive secretion of VIP (vasoactive intestinal peptide) by an islet cell tumour of the pancreas. Sometimes called WDHA syndrome. See: Verner-Morrison syndrome, WDHA syndrome. Synonym: pancreatic cholera, pancreatic diarrhoea. (05 Mar 2000) |

| cholera bacillus | <bacteria> Bacterium that causes cholera, the life threatening aspects of which are caused by the exotoxin (see cholera toxin). Short, slightly curved rods, highly motile (single polar flagellum), gram-negative.
