This news article doesn't appear to report anything that has not been reported in the news over the past few years. Pimental and SIBO have in the news on and off for a few years. He is the one who proposed the use of the lactulose breath test to determining SIBO and the use of non-absorbable antibiotics such as Rifaximin (Xifaxin) for treatment.
Recently there have been a series of article that question the reliability of the test to distinguish SIBO individuals from controls. Frequently after treatment with antibiotics the IBS symptoms return again. There have been a number of people on the board who have tried Rifaxamin with short term or poor results. I don't recall see anyone post with long term positive results using this antibiotic.
SIBO, its relationship to IBS and treatment with antibiotics is still a questionable approach requiring more investigation. It may be helpful to some but it does not appear to be as useful a therapeutic approach for managing IBS as originally thought.
