Enteritis is an intestinal inflammation which bounds to small intestine. If the large intestine is affected, you would speak about enterocolitis.
Both human beings and animals might be hitten by enteritis. The most common cause of enteritis are bacteriums and viruses, but also malnutrition could trigger off enteritis.
Sickened animals have diarrhoea and show lack of appetite. Of course only the veterinary should make that diagnosis.
It is possible to apply natural products apart from conventional pharmaceutical.
