Reviewer's report:  
 
Intestinal microbiota has been subject for many researches a nd has been hot topic current, as it 
has been linked to many diseases including CD. It has been shown in Western researches that 
alteration in the intestinal microbiota contributes to pathophysiology for many GI diseases. This 
study sheds light on this top ic in the Asian population and it is worthwhile to be published in 
BMC Gastroenterology journal. I think many readers will be interested in this article.
