Hemorrhagic gastroenteritis is identified by blood in the vomit and/or stool, often due to a food borne illness. Because it is a serious disorder than can be potentially fatal, immediate veterinary care is required.
Infectious gastroenteritis is caused by pathogens (infectious agents). Some of the pathogens most commonly associated with infectious gastroenteritis include:
E. coli, Salmonella and Corynebacterium are the most significant intestinal pathogens because they can be passed from animal to human or vice versa. Salmonella infections are also important due to association with reproductive disorders.
Sudden dietary changes and/or dietary toxins may cause irritation and/or affect the immune system. Eosinophilic gastroenteritis, a chronic form of the illness, has been associated with allergens in dog foods. Gastroenteritis may be also observed due to irritation caused by stress, toxins, physical obstruction, ulcers, and abdominal disorders.
Gastroenteritis is not specific to any breed or gender, however, small breed dogs are more prone to infectious gastroenteritis.
It may be difficult to identify the cause of gastroenteritis. Therefore, invasive diagnostic procedures may be required if routine diagnostic procedures are not successful.
A brief outline of diagnostic procedures:
Routine blood/biochemical tests:
Examination through feeling
Something that is related to the whole body and not just one particular part or organ
A type of slime that is made up of certain salts, cells, or leukocytes
A medical condition in which the small intestine and stomach become inflamed
a) Mass per volume b) The number of animals in a given area
A medical condition in which the body has lost fluid or water in excessive amounts
The digestive tract containing the stomach and intestine
