Bacterial enteropathies should really be regarded as "overgrowths".

==[[Clostridial Diseases - Rabbit]]==

==Colibacillosis==
{{unfinished}}
It can be encountered in pet rabbits of all ages, especially if they have been receiving doses of antibiotics that include gram-positive organisms in their spectrum of activity (Morisse 1978). This can be a particular problem if animals from different sources are mixed together on acquisition, especially in conditions of indifferent hygiene. The quality of the diet (especially the protein/cellulose ratio) and of the drinking water is also of aetiological importance. The levels of ''E. coli'' in the intestinal lumen of a rabbit rises directly in proportion to infestation with ''Eimeria'' species (coccidians).

===Clinical Signs===
*profuse diarrhoea
*fur-chewing
*anorexia

===Treatment===
Treatment is usually unrewarding.
*Oral administration of broad-spectrum antibiotics with known activity against gram-negative organisms, including ''E. coli''.
*Antispasmolytic agents such as hysocine (Buscopan Compositum; Boehringer Ingelheim 1 mg per kilogram I/M or S/C once only or daily until the desired results are obtained)
*Fluids. Okerman (1994 p 37) warns that finding ''E. coli'' in large numbers merely reflects the ability of the organism to reproduce post-mortem and does not necessarily prove the diagnosis.

==Tyzzer's disease (or bacillary typhilitis)==
{{unfinished}}
Tyzzer's disease is caused by the obligatory intracellular ''Clostridium (formerly Bacillus) piliformis'', a gram-variable organism diagnosed on post-mortem examination by histopathology utilising Giemsa or Warthin-Starry staining techniques (Walden 1990). The organism may be seen on impression smears of the ileum lining (see Okerman 1994). The organism does not grow on broth or agar. Predisposing causes in rabbits are not known (Carman 1994) but weanlings are most frequently affected.

Symptoms include acute depression, watery diarrhoea and a high mortality rate) or chronic weight loss. Post-mortem findings include dehydration, oedema of the intestinal wall, necrosis of the colonic and caecal mucosa, and occasionally many necrotic foci in the liver.

Treatment is not generally recommended but may be attempted (tetracyclines). The disease has also been reported under circumstances which suggested that it may be spread by wild mice (MAFF monthly report 080892).

==Salmonellosis==
{{unfinished}}
Salmonellosis is due to ''Salmonella typhimurium'' which has been recorded as manifesting a severe enteritis in baby rabbits. Clinical signs include depression, fever, +/- diarrhoea, abortion (Okerman 1994). Salmonellosis is a zoonosis.

==Pseudotuberculosis==
{{unfinished}}
(syn: rodentiosis)
Pseudotuberculosis is not just a condition of the gastrointestinal tract. Infection with ''Yersinia pseudotuberculosis'' as a result of direct or indirect contact with infected rodents or wild birds is encountered occasionally. The provision of freshly gathered wild plants or unwashed vegetables must be considered as a source of infection. Clinical signs include cachexia with an enlarged spleen being detected on abdominal palpation. Diagnosis is usually made on post-mortem examination, the organism being isolated from the typical lesions - necrotic foci in the lymphoid tissue of the spleen, caecum and ileo-caecal. Treatment and prevention of spread of the infection to contact animals is by the use of oral fluoroquinolones. Further prevention is via rodent control.

==Synopsis of treatment for enterotoxaemia and bacterial enteritis==
{{unfinished}}
*Warmth up to 27°C
*Fluid therapy
**Hartmann’s is probably better than dextrose-containing fluids (Clostridial toxins “feed” on monosaccharides)
**intravenous or intraosseous.
**maintenance = 100ml/kg/day
*Analgesia
**buprenorphine
**butorphanol
**carprofen
*Cholestyramine resin (Questran, Bristol-Myers Pharmaceuticals) - rabbit must be well-hydrated because the same chain of events occur when ispaghula husk (psyllium) is given to rabbits (see anatomy and physiology of the digestive tract).
*Antibiotics are indicated if it is a true bacterial enteritis but should be avoided if ''Salmonbella'' sp. is isolated.
*Probiotics. ''Lactobacillus'' spp are claimed to attach to mucosa and compete with pathogenic bacteria.
*Transfaunation
**Caecotrophs collected from a healthy rabbit
**Elizabethan collars
**Fed whole to maintain the protective mucus coating
*Rabbits with diarrhoea should never be starved
**Ad lib hay and leafy greens. Dandelions, parsley, freshly pulled (not cut) grass and groundsel
**Assisted feeding – commercial high fibre products for herbivores are available (eg). Most rabbits will accept food orally may be necessary.
**Vitamin C may be of use in limiting the absorption of iota toxins and improving mucosal integrity
**Oxbow Critical care for herbivores,
**Supreme Recovery Diet via a syringe or nasogastric intubation
