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

Gut microbes, and particularly probiotic bacteria, modulate the barrier integrity by reducing gut permeability and reinforcing tight junctions. Probiotic Escherichia coli Nissle 1917 (EcN) is a good colonizer of the human gut with proven therapeutic efficacy in the remission of ulcerative colitis in humans. EcN positively modulates the

Strain CFT073 is a bona fide uropathogen, whereas strains 83972 and Nissle 1917 are harmless probiotic strains of urinary tract and faecal origin, respectively. Despite their different environmental origins and dispositions the three strains are very closely related and the ancestors of 83972 and Nissle 1917 must have been very similar to CFT073. In a recent article published in Nature, Roger Geiger’s research group showed that the engineered bacterial strain Escherichia coli Nissle 1917 (ECN) could recycle ammonia into L-arginine (Arg
These intelligent responsive bacteria for diagnosis and therapy (i-ROBOT) consists of E. coli Nissle 1917 that responds to levels of the inflammatory marker thiosulfate by activating a base-editing system to generate a heritable genomic DNA sequence as well as producing a colorimetric signal.
