enteritis

inflammation of the intestinal mucosa resulting in clinical signs of diarrhea, sometimes dysentery, abdominal pain and dehydration and electrolyte loss and imbalance. In more severe cases there is much mucus in the feces and in the worst ones there are shreds or even sheets of exfoliated mucosa. Gastritis is commonly an accompanying lesion. Vomiting may be a concurrent sign in monogastric animals. The causes are many and include bacteria, viruses, chemicals, damaged feedstuffs and nematode parasites and protozoa. Descriptions of those diseases will be found under the headings of their causative agents, e.g. rotavirus, coronavirus, enterovirus, Salmonella. There is a further list of diseases in which diarrhea is the cardinal sign but in which there are no lesions of enteritis. These are the enteropathies. See also enteropathy.

canine viral enteritis

common causes in dogs are canine parvoviruses, coronavirus and rotavirus. Other viruses isolated from dogs with enteritis but of unknown clinical significance are astrovirus, calicivirus and parainfluenza virus.

feline enteritis

granulomatous enteritis

horses with this disease continue to lose condition over a long period and most have diarrhea and edema. There is a hypoproteinemia and protein loss in the feces. In dogs, the changes are similar, but may be segmental and can be the cause of partial obstruction.

hemocytic enteritis

enteritis of shrimps associated with blooms of some blue-green algae.

lymphocytic-plasmacytic enteritis

infiltration of the lamina propria with lymphocytes and plasma cells can be a nonspecific response to chronic inflammation, but is classified by some as a primary, immune-mediated disease of the intestine causing malabsorption, chronic watery diarrhea and sometimes a protein-losing enteropathy.

phlegmonous enteritis

turkey coronaviral enteritis

acute, highly infectious disease of turkeys of all ages characterized by inappetence, wet droppings, weight loss and heavy mortality is caused by a coronavirus. Called also bluecomb disease.

turkey hemorrhagic enteritis

caused by an adenovirus this disease affects turkey poults over 4 weeks old and is characterized by bloody droppings and sudden death. An epidemic disease now very widespread.

ulcerative enteritis

an acute disease of chickens, poults and game birds caused by Clostridium colinum. It is characterized by rapid spread of an acute symptomless disease. Quail show watery white droppings. Lesions include hemorrhagic enteritis in acute cases with ulceration the major finding in subacute cases. The morbidity in quail may be 100%, in chickens it is nearer 10%. Called also quail disease.
