Inflammatory bowel disease(IBD)is a chronic intestinal inflammatory disease with an increasing incidence rate year by year,but its etiology is still unclear.And there is a lack of well-targeted and safe therapeutic drugs.In recent years,probiotics have shown large potential as a potential treatment strategy for the prevention and treatment of IBD.This paper elaborates on the mechanism of probiotics in the treatment of IBD,summarizes common probiotic species used in the treatment of IBD,and looks forward to the application of probiotics,aiming to lay a foundation for the research on probiotics in the treatment of IBD.
