Rabbit GI diseases Flashcards
Cheek tooth occlusion angulation
Should have a 10 degree angulation from flat contact
Categories of dental disease complex
-Congenital: dwarfs and lop eared
-Acquired
Pathophysiology of dental disease complex
-Elongation of cheek teeth causing bending
-Reduced occlusal wear
-Rabbit modifies chewing motion because lateral to lateral movement is not effective
-Abnormal wear
-Elongation of reserve crown causes damage to bone and perforates cortical bone
-Vascular damage and growth deficits of teeth
Early stage of dental disease
-Increased selectivity of dietary items
-Hyporexia
-Hypersalivation
-Difficult prehending food items
-Bumpy or swollen ventral mandible
Late stage dental disease
-Epiphora
-Facial swelling
-Exophthalmos
-Oral abscesses
-Halitosis
Secondary signs of dental disease
Reduced size and volume of fecal output, dry stool, irregular fecal balls
Gastro intestinal pain
Poor coat condition
Conjunctivitis and ocular disease
Metabolic bone disease
Primary pathogens of dysbiosis
-Clostridium spiroforme
-E coli
-Lawsonia intracellularis
-Clostridium piliforme
Non pathogen dysbiosis
Bacteria are typically at low density but are allowed to overwhelm the normal gastrointestinal flora
Causes of non pathogen dysbiosis
-Excess carbohydrate exposure
-Changes in production or absorption of VFAs
-Antibiotic administration
-Normal bacteria are starved of high fiver substrate
Safe antibiotics
Metronidazole
Enrofloxacin
Doxycycline
Chloramphenicol
Azithromycin
TMS
What stimulates gut motility
Dietary fiber
Where do large and fine fiber particles
High fiber-> propelled through colon quickly
Fine fiber-> travel back from colon to cecum
Problem with pylorus
Very sharp angle so easily compressed by duodenum
pH of stomach
<2 in adults
Neutralize bacteria ingested with cecotrophs
5-6.5 in neonates
Problem with high carb diets
-Excess glucose-> Clostridium and E coli proliferate
-Excess VFA-> lower cecal pH-> normal flora inhibited-> gas and toxins
-Slower GI motility
