Specifically, we focus on probiotic E. coli Nissle 1917 and interrogate its effect on persister survival and DNA repair during the post-fluoroquinolone treatment period. Escherchia coli Nissle was isolated from a soldier who remained healthy during a dysentery outbreak in a German field hospital at the height of World War I (Sonnenborn, 2016). 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. The aim of the current study was therefore to investigate the antimicrobial and antibiofilm activities of a range of bacteria including organisms isolated from human skin, and the candidate probiotic E. coli Nissle 1917. E. coli Nissle 1917 is a commonly studied candidate probiotic bacterium. Probiotic microorganisms are defined as viable nutritional agents conferring benefit to the health of the human host. Especially, Escherichia coli strain Nissle 1917 (EcN) was shown to be equally effective as mesalazine in the maintenance of remission in ulcerative colitis (UC). Presumably, the ther … Omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have beneficial effects on human health. The probiotic bacterium Escherichia coli Nissle is unable to produce either EPA or DHA. Escherichia coli Nissle was transformed with the pfBS-PS plasmid carrying the EPA/DHA gene cluster, previously isolated from a EcN grows very well at the normal as well as at stressful conditions and exhibits high level of transformation efficiency and greater ability to retain heterogenous plasmid, and is highly resistant to P1 phage infection. Escherichia coli Nissle 1917 (EcN) is one of the probiotics that has drawn more attention from researchers in recent days as it extends many host beneficial effects. dmS9P2.
