Editing Enteritis (section)

== Diagnosis ==
Diagnosis may be simple in cases where the patient's signs and symptoms are [[Idiopathic disease|idiopathic]]. However, this is generally not the case, considering that many pathogens which cause enteritis may exhibit similar symptoms, especially early in the disease. In particular, ''Campylobacter'', ''Shigella'', ''Salmonella'' and many other bacteria induce acute self-limited colitis, an inflammation of the lining of the colon which appears similar under the microscope.<ref name=":1" />

A medical history, physical examination and tests such as blood counts, stool cultures, CT scans, MRIs, PCRs, colonoscopies and upper endoscopies may be used in order to perform a differential diagnosis.<ref name=":2" /><ref name=":3" /><ref name=":6" /><ref>{{Cite journal|last1=Gregg|first1=Clark R.|last2=Nassar|first2=Naiel N.|s2cid=27491100|date=1999-04-01|title=Infectious Enteritis|pmid=11096582 |journal=Current Treatment Options in Gastroenterology|volume=2|issue=2|pages=119–126|issn=1092-8472|doi=10.1007/s11938-999-0039-9}}</ref> A biopsy may be required to obtain a sample for histopathology.{{citation needed|date=October 2022}}
