Alcohol abuse increases the risk of acute liver injury. Escherichia coli Nissle 1917(EcN) has been comprehensively demonstrated as a safe oral probiotic. In this study, we genetically modified EcN expressing alcohol dehydrogenase gene, acetaldehyde dehydrogenase gene, NAD synthase gene, and NADH oxidase gene.
Dr. Nissle isolated an E. coli strain that showed strong antagonistic activity against pathogenic bacteria (Yes, an E. coli was helping, a bacterium commonly associated with food recalls and digestive illness). This heroic strain of E. coli was named after Dr. Nissle, becoming E. coli Nissle 1917.
Characteristics of E. coli Nissle 1917. Escherichia coli Nissle 1917 (EcN) is a Gram‐negative probiotic, originally isolated by Dr. Alfred Nissle during World War I (Nissle, 1918; Nissle, 1925).EcN is serum‐sensitive and does not produce any enterotoxins or cytotoxins associated with pathogenic E. coli strains (Sonnenborn and Schulze, 2009).It has been licensed as a pharmaceutical for the
Evaluation of the effects of E. coli Nissle 1917 in the LPS-induced model of septic shock in mice. The mice were randomly assigned to three groups (n= 10); two of them (healthy and control groups) received tap water and the other (treated group) received the probiotic strain suspended in drinking water at the final concentration of 10 8 CFU·mL −1, prepared daily.
Studies have shown that EcN may be therapeutically effective in a variety of conditions such as ulcerative colitis, diarrhoea and chronic constipation. The E. coli strain Nissle 1917 is characterised by a number of features that set it aside from the rest of its family members. As a potent probiotic, it can work to promote digestive health.
Escherichia coli strain Nissle 1917 (EcN) has been used as a probiotic. Genetic engineering has enhanced the utility of EcN in several vaccine and pharmaceutical preparations. We discuss in this mini review the genetics and physical properties of EcN. We also discuss the numerous genetic engineering strategies employed for EcN-based vaccine JqzNJIT.
