Actinobacillus and Actinomyces
Wooden Tongue and Lumpy Jaw (firm, fibrous, nodular, massive expansion). Secondary invaders.
in dogs, causing hemorrhage, necrosis, edema and fibrin deposition in the pancreas
annular constricting band of abundant fibrous tissue. Very malignant, will seed the abdomenal serosa/ metastisize to the liver and LN
Aeromonas is a gram - bacterial infection of what sepcies and what does it cause?
fish and reptiles; necrosis and hemorrhage in the mouth and other organs
small animals ingesting poisons like warfarin get this disease (bleeding in the GIT)
accumulation of clear, yellow fluid in the abdomen, associated with hyperproteinuria. Caused by Chronic Liver Disease and Right Heart Failure.
no anus, congenital defect in cattle
colon ends in a blind sac somewhere before the anus
viral infection, esophagus oral cavity and crop
cause of ruminal ulcers, due to grain overload (lactic acidosis and CO2 gas production) or ingestion of certain legumes with high soluble protein. Rumen filled with foam and froth. Lactic Acid damages the rumen mucosa and causes ulcers.
sharp line of demarcation in the esophageal mucosa at the thoracic inlet (crainial is congested, intrathoracic is blanched and pale)
horses that engorge on grain = lot of CO2 gas. causes CV failure, shock, stomach rupture, peritonitis, and death.
Bovine papular stomatitis
viral infection; discrete circular raised lesions in mouth and esophagus (incidental)
Ulcer over the Peyers patches in cattle small intestine
opportunistic yeast infection of immunocompromised animals (thrush)
Causes of Excess Fluid in a normal SI
E coli, Rotovirus/ Coronavirus, Cryptosporidia, Clostridium p. D, Lymphangiectasia, IBD, Panleuk
Causes of Hemorrhage in the Stomach/ Abomasum
Heavy Metals (ulceration, bleeding, hemorrhage) and Uremia in dogs (toxins damage blood vessels) (and BVD)
Causes of Ulcers in Small Intestine
Salmonella (cattle), BVD (cattle), Amoeba (reptiles), Ulcerative enteritis (poultry)
Causes of Ulcers in the Stomach/ Abomasum
Horse: Gastophilus larvae along the margo picatus, NSAIDs, stress (all species). Pigs: + ulcers in the esophageal portion of the stomach (genetics, feed?)
Chronic cases of coccidia
small nodules and plaques in the mucosa of SI
