Discrepant Tests for Hydrogen Sulfide.
Kligler and Triple Sugar Iron (TSI) media have been considered to be interchangeable for the purpose of detecting hydrogen sulfide production in the family Enterobacteriaceae. Contrary evidence is presented in this report. From various sources, 11 cultures were isolated which yielded a positive hydrogen sulfide reaction on Kligler medium and a negative reaction on TSI. Biochemically, these cult...
متن کاملUse and abuse of hydrogen breath tests.
Hydrogen breath tests are widely used to explore the pathophysiology of functional gastrointestinal disorders. Small intestinal bacterial overgrowth and carbohydrate malabsorption are disorders detected by these tests that have been proposed to be of great importance for symptoms in, for instance, irritable bowel syndrome. However, conclusions drawn from these studies are highly controversial a...
متن کاملImplementation and interpretation of hydrogen breath tests.
Hydrogen breath tests are non-invasive and safe diagnostic tools used to investigate functional intestinal disorders. For the diagnosis of fructose or lactose malabsorption as well as for the detection of small intestinal bacterial overgrowth syndrome, hydrogen breath tests are even regarded as gold standard. However, standardization of the testing procedure and the interpretation of the test r...
متن کاملHow to Interpret Hydrogen Breath Tests
Hydrogen breath tests using various substrates like glucose, lactulose, lactose and fructose are being used more and more to diagnose small intestinal bacterial overgrowth (SIBO) and lactose or fructose malabsorption. Though quantitative culture of jejunal aspirate is considered as gold standard for the diagnosis of SIBO, hydrogen breath tests, in spite of their low sensitivity, are popular for...
متن کاملAssociation between Symptoms of Irritable Bowel Syndrome and Methane and Hydrogen on Lactulose Breath Test
Whether hydrogen and methane gas produced during lactulose breath test (LBT) are associated with symptoms of irritable bowel syndrome (IBS) is not determined. We aimed to investigate whether hydrogen and methane on LBT are associated with IBS symptoms. Sixty-eight IBS patients meeting the Rome III criteria for IBS, and 55 healthy controls, underwent LBT. The IBS subjects recorded their customar...
