Abstract. Background and aims: Escherichia coli Nissle 1917 (EcN) has been recommended as a therapeutic tool for ulcerative colitis (UC) treatment. However, to date, no meta-analysis has been performed on this topic. Methods: We performed a literature search on PubMed, MEDLINE, Science Direct and EMBASE. We evaluated success rates for induction Escherichia coli Nissle (EcN) is a nonpathogenic Gram-negative strain isolated in 1917 by Alfred Nissle and it is the active component of microbial drug Mutaflor(®) (Ardeypharm GmbH, Herdecke, Germany and EcN, Cadigroup, In Italy) used in many gastrointestinal disorder including diarrhea, uncomplicated diverticular disease and UC. Despite the great progress of current bacterially based biotherapeutics, their unsatisfying efficacy and underlying safety problems have limited their clinical application. Herein, inspired by probiotic Escherichia coli strain Nissle 1917, probiotic-derived outer membrane vesicles (OMVs) are found to serve as an effective therapeutic platform for the treatment of inflammatory bowel disease To create a TAA-independent ProCAR platform, we engineered a well-characterized probiotic strain, Escherichia coli Nissle 1917 (EcN), which is equipped with a genomically integrated, synchronized lysis circuit (SLIC) for quorum-regulated delivery of synthetic CAR targets directly to the tumor core. Escherichia coli Nissle (EcN) 1917 is a Gram-negative probiotic that was shown to be highly efficient in protecting gnotobiotic (Gn) piglets against HRV infection and disease by modulating innate and adaptive immunity, and directly protecting the intestinal epithelium by binding to HRV particles [24,25].

We genetically engineer Escherichia coli Nissle 1917 (EcN) to create fibrous matrices that promote gut epithelial integrity in situ. These matrices consist of curli nanofibers displaying trefoil Bacterial cancer therapy was developed using probiotic Escherichia coli Nissle 1917 (EcN) for medical intervention of colorectal cancer. EcN was armed with HlyE, a small cytotoxic protein, under njlq.
