Researchers Question Antibiotic Treatments. Many symptoms of Crohnâs diseaseâsuch as abdominal pain, cramping, and severe diarrheaâare caused by inflammation of the lining of the gastrointestinal tract.Treatments are often aimed at toning down that inflammation either with anti-inflammatory or immune-suppressing drugs.he harmful organisms that thrived in the guts of people with Crohnâs disease included ones in the same family as Salmonella and Escherichia coli, as well as several other groups of bacteria. Beneficial bacteria that were more rare included Bifidobacterium and other families of microbes.
