For this purpose, healthy C57BL/6 mice were perorally administered probiotics for 3 weeks. A total of five common probiotic strains, Lactobacillus rhamnosus species GG (LGG) and LC705, Bifidobacterium breve 99 (Bb99), Propionibacterium freudenreichii Shermanii JS (PJS), and Escherichia coli Nissle 1917 (EcN), and two of their mixtures, were tested.
Escherichia coli Nissle 1917 (EcN) is a non-pathogenic gram-negative bacterium belonging to the Enterobacteriaceae family . In contrast to other E. coli strains, this strain does not produce virulence factors and reduces colonic mucosal damage by stimulating the production of human beta-defensin 2, a crucial molecule that protects the mucosal
The probiotic Escherichia coli strain Nissle 1917 (EcN) is one of the few probiotics licensed as a medication in several countries. Best documented is its effectiveness in keeping patients suffering from ulcerative colitis (UC) in remission. This might be due to its ability to induce the production …
Escherichia coli Nissle 1917 (EcN) is among the best characterised probiotics, with a proven clinical impact in a range of conditions. Despite this, the mechanisms underlying these "probiotic effects" are not clearly defined. Here we applied random transposon mutagenesis to identify genes relevant to the interaction of EcN with intestinal epithelial cells. This demonstrated mutants disrupted
In the quest for mitigators of bacterial virulence, cell-free supernatants (CFS) from 25 human commensal and associated bacteria were tested for activity against Pseudomonas aeruginosa. Among these, Escherichia coli Nissle 1917 CFS significantly inhibited biofilm formation and dispersed extant pseudomonas biofilms without inhibiting planktonic bacterial growth. eDNA was reduced in biofilms
