BREAKING: Specific gut bacteria found for Crohn's disease

Researchers have identified specific gut bacteria found in people with Crohn’s disease that they say could mean better treatment. Scientists for the the new study say though they still don’t know the exact cause of Crohn’s their findings point to an autoimmune response to specific bacteria in the intestines.

Originally reprinted from

The large study is a collaborative effort of 28 gastroenterology centers investigating how microbes in the gut contribute to bowel inflammation.

For their discovery the researchers obtained biopsies from 447 people with Crohn’s disease from various parts of the intestine who were newly diagnosed. The researchers compared the results to 221 people without Crohn’s disease.

Patients with Crohn’s disease that were newly diagnosed had an abundance of disease causing bacteria and were missing microbes that are beneficial.

Finding a better therapy

The study also showed missing beneficial bacteria in the intestines correlated with increased Crohn's disease activity.

The study authors write their finding showed "...increased abundance in bacteria which include Enterobacteriaceae, Pasteurellacaea, Veillonellaceae, and Fusobacteriaceae, and decreased abundance in Erysipelotrichales, Bacteroidales, and Clostridiales," that also paralleled increased Crohn's disease activity.

"These findings can guide the development of better diagnostics," says senior author Dr. Ramnik Xavier of Massachusetts General Hospital and the Broad Institute of MIT and Harvard in a press release. But Xavier adds the most important finding is that there are specific organisms in the gut that are either increased or decreased in people with Crohn’s disease, which could mean better therapies.

An example is antibiotics used to treat children with Crohn’s disease. The researchers say some of the medications wipe out good bacteria while causing an increase in harmful intestinal microbes.

To validate their findings the researchers also sampled 1,742 pediatric and adult patients with either new-onset or established Crohn’s disease, using various methods of detecting gut bacteria. They discovered testing rectal tissue; not fecal sampling could indicate Crohn’s disease even in the absence of symptoms. What that means is less invasive ways to diagnose Crohn’s disease early.

The finding is published in the journal Cell Host & Microbe.

Past studies show early intervention with TNF agents leads to better outcomes of the debilitating condition but one of the barriers for initiating early treatment is the time it takes to diagnose the disease. The new and large study shows IBD including Crohn's disease could be diagnosed more easily by looking at gut bacterial balance. It also shows an underlying cause of Crohn's disease that is an autoimmune response to bacteria in the gut.

Every day a new intresting article. I'm sure in the next 10 years we will get to the bottom of this.

I also believe that within years, with God's blessing, the science will find the treatment for Crohn's Disease.

Interesting I think this research will eventually assist in the discovery that Crohn's disease among other diseases is actually a result of the neurological functioning of the immune system going haywire as opposed to the intestines alone. The reason why I believe this relates to this study is because if from the root of the immune system, the brain tells the intestines they are infected with a nefarious substance, virus, bacteria whatever and the brain triggers the immune system to kill all normally beneficial bacteria allowing bad bacteria to over run the gut causing some of the symptoms then we are half way to figuring out the root cause of why this happens. We need to just connect the dots from there.

Very interesting! I am currently undiagnosed crohns. In 1999 I had a major bowel resection surgery due to a perforation. They removed 12 ins of small bowel and 6 inches of colon in the process. Pathology came back as a yersinia infection which I believe is in the family of Enterobacteriaceae.... Which was found in the gut of Crohn's disease patients! There may be hope for me for a diagnosis!! As a matter of fact I am scheduled next month @ MGH with Dr. Ramnik Xavier who was involved in the study. Hopefully he can finally give me an answer!!
