🐲 E Coli Nissle 1917 Probiotyk

E. coli translocation and dissemination and the mortality of mice were assessed. In GF-raised Rag1(-/-) mice, but not in SPF-raised Rag1(-/-) mice or GF-raised C57BL/6J mice, oral challenge with E. coli strain Nissle 1917, but not oral challenge with E. coli mpk, resulted in translocation and dissemination. Feb 1, 2023 · Benefiting from its good biocompatibility and ideal targeting ability as a biological carrier, Escherichia coli Nissle 1917 (ECN) has been focused on the treatment strategies of inflammatory bowel disease and tumor. The advantage of a bacterial carrier is that it can express exogenous protein while also acting as a natural capsule by releasing Apr 9, 2004 · The probiotic Escherichia coli strain Nissle 1917 (Mutaflor) of serotype O6:K5:H1 was reported to protect gnotobiotic piglets from infection with Salmonella enterica serovar Typhimurium. An important virulence property of Salmonella is invasion of host epithelial cells. Therefore, we tested for inte … Jan 1, 2017 · Escherichia coli strain Nissle 1917 (EcN) is a remarkable probiotic bacterium, first described by Alfred Nissle in 1916/17. As the active component of Mutaflor, EcN has been well researched over decades but detailed mechanisms by which EcN confers its probiotic effects are still elusive. Feb 5, 2014 · The aim of this study was to find whether probiotic E. coli strain Nissle 1917 (EcN) influences the pharmacokinetics of concomitantly taken antiarrhythmic drug amiodarone (AMI). Live bacterial suspension of probiotic EcN (or non-probiotic E. coli strain ATCC 25922) was applied orally to male Wistar rats for seven days, while a control group of Apr 1, 2004 · EcN was originally isolated by Alfred Nissle in 1917 in course of a search for E. coli wild-type strains with antagonistic activity against enteric pathogens. Later it was shown that this strain produced some novel kind of colicin(s) of low-molecular mass [17 , 18] , nowadays called microcins [16] . Aug 2, 2023 · In this study we performed a step-wise optimization of biologically active IL-2 for delivery using E. coli Nissle 1917. Engineering of the strain was coupled with an in vitro cell assay to measure Sep 14, 2021 · The programmable engineering platform is further developed for the controlled and effective colonization of Escherichia coli Nissle 1917 (EcN) in the gut. The colonizing bacteria effectively alleviate DSS-induced colitis in mice. Jun 6, 2016 · 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. It is the Mar 26, 2007 · Escherichia coli strain Nissle 1917 (EcN) of the serotype 06:K5:H1 is a well-characterized probiotic bacterium originally isolated by Dr Alfred Nissle in 1917 from the faeces of a soldier who stayed unaffected during a severe outbreak of shigellosis (Nissle 1918). Jul 1, 2023 · CCK-8 assay, Hoechst 33258 staining and flow cytometry analysis were used for examining cytotoxicity of tumoricidal protein azurin toward CT26 cells. An engineered probiotic Ep-AH harboring azurin and hlpA genes was developed using Escherichia coli Nissle 1917 (EcN) chassis. Antitumor effects of Ep-AH were evaluated in the azoxymethane (AOM Aug 22, 2017 · Campylobacter jejuni is a leading cause of bacterial food poisoning in humans. Due to the rise in antibiotic-resistant Campylobacter, there exists a need to develop antibiotic-independent interventions to control infections in humans. Here, we evaluated the impact of Escherichia coli Nissle 1917 (EcN), a probiotic strain, on C. jejuni’s invasion and intracellular survival in polarized human zBXCj.
