However, the precise etiology of IBD is still unknown and effective therapeutics are yet to be discovered. It is becoming increasingly clear that a combination of factors, including genetic background, host immune response, and microbial reduced diversity status are related to IBD. The cardinal symptom of IBD patients is the imbalance of the intestinal microflora. According to previous studies, both probiotics and symbiotic microbiota can play a protective role through intestinal micro-ecosystem regulation, epithelial barrier integrity enhancement, and inflammation reduction. Therefore, probiotics can provide an alternative or auxiliary method to traditional IBD treatment. Here, we reviewed the possible pathogenesis of IBD, summarized the possible mechanisms of probiotics modulation of IBD, and emphasized the prevention and treatment targets of probiotics-mediated IBD, with the aim to provide theoretical support for the treatment of IBD patients by probiotics in clinical trials.","PeriodicalId":73374,"journal":{"name":"Infectious microbes & diseases","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43145400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These effects were termed heterologous, non-specific or off-target effects and have been shown to be due to both innate and adaptive immune system responses. Experiments carried out in a bid to further understand these effects led to many more discoveries about the applicability of the BCG vaccine for the prevention, diagnosis, and treatment of certain disease conditions. As we approach the second century since the discovery of the vaccine, we believe it is timely to review these interesting applications of the BCG vaccine, such as in the prevention of diabetes, atherosclerosis, and leukemia; the diagnosis of Kawasaki disease; and the treatment of multiple sclerosis, non-muscle invading bladder cancer, and stage III melanoma.
