Which of the following can cause enteritis?

Enteritis refers to the inflammation of the intestine, particularly the small intestine, which can lead to symptoms such as diarrhea, abdominal pain, and vomiting. The cause of enteritis is often linked to infectious agents, specifically bacteria and viruses.

Bacteria such as Salmonella, Escherichia coli, and Campylobacter are well-known culprits that can infect the intestinal lining, resulting in inflammation and associated symptoms. Viruses like rotavirus and norovirus have also been identified as key contributors to enteritis, especially in young animals and certain species. The presence of these pathogens triggers an immune response, leading to inflammation and the symptoms characteristic of enteritis.

Other options such as physical injuries, genetic mutations, and environmental pollution do not directly cause enteritis in the same manner. While physical injuries can lead to various digestive system complications, they do not specifically cause inflammation of the intestines as bacterial and viral infections do. Genetic mutations can predispose animals to various health issues but are not a direct cause of enteritis. Environmental pollution can have adverse effects on health, but it does not directly lead to the infectious nature of enteritis as the pathogenic organisms do. Therefore, the role of bacteria and viruses in causing enteritis is well established, explaining
