Sulphate-reducing bacteria and hydrogen sulphide in the aetiology of ulcerative colitis.

The article examines the role of sulphate-reducing bacteria (SRB) and hydrogen sulphide in the etiology of ulcerative colitis. A literature search was conducted using the PubMed database and search terms "sulphate reducing bacteria," "hydrogen sulphide," "ulcerative colitis," "mucous gel layer" and "trans-sulphuration."
