Other common causes of infectious enteritis include bacteria such as Shigella and E. coli, as well as viruses such as adenovirus, astrovirus and calicivirus. Other less common pathogens include Bacillus cereus, Clostridium perfringens, Clostridium difficile and Staphylococcus aureus.Campylobacter jejuni  is one of the most common sources of infectious enteritis, and the most common bacterial pathogen found in 2 year old and smaller children with diarrhoea. It has been linked to consumption of contaminated water and food, most commonly poultry and milk. The disease tends to be less severe in developing countries, due to the constant exposure which people have with the antigen in the environment, leading to early development of antibodies.Rotavirus is responsible for infecting 140 million people and causing 1 million deaths each year, mostly in children younger than 5 years. This makes it the most common cause of severe childhood diarrhoea and diarrhea-related deaths in the world. It selectively targets mature enterocytes in the small intestine, causing malabsorption, as well as inducing secretion of water. It has also been observed to cause villus ischemia, and increase intestinal motility. The net result of these changes is induced diarrhoea. Enteritis necroticans is an often fatal illness, caused by β-toxin of Clostridium perfringens. This causes inflammation and segments of necrosis throughout the gastrointestinal tract. It is most common in developing countries, however has also been documented in post-World War II Germany.
Studies have shown the efficacy of antibiotics in reducing the duration of the symptoms of infectious enteritis of bacterial origin, however antibiotic treatments are usually not required due to the self-limiting duration of infectious enteritis. Etymology
The word enteritis () uses combining forms of entero- and -itis, both New Latin from Greek, respectively from ἑντερον (enteron, small intestine) and -ιτις (-itis, inflammation). See also
