May 20, 2020 · In this work, we have engineered a model probiotic organism, Escherichia coli Nissle 1917 (EcN, serotype O6:K5:H1), to produce butyrate from genomic loci up to approximately 1 g/L (11 mM). Then, for real-time monitoring of butyrate production in cultures, we developed a high-throughput biosensor that responds to intracellular butyrate
Dec 10, 2023 · Bioengineered probiotics enable new opportunities to improve cancer treatment strategies due to their tumor-colonizing capabilities. Here, we will describe the development of a probiotic E. coli Nissle 1917 platform encoding a synchronized lysis mechanism for the
Oct 5, 2021 · Among the beneficial strains, E. coli Nissle, isolated in 1917, has been the most extensively explored strain. Adaptability to survive under diverse conditions coupled with facile genetic manipulations enabled the design of E. coli strains with properties to deliver antioxidant, anti-inflammatory, and antitumor molecules.
Sep 29, 2016 · The future of probiotic E. coli may lay in what Alfred Nissle originally discovered: to treat gastrointestinal infections, which nowadays are often caused by antibiotic-resistant pathogens. A century ago, Alfred Nissle discovered that intentional intake of particular strains of Escherichia coli could treat patients suffering from infectious diseases. Since then, one of these strains became the
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
Oct 11, 2019 · The contents of the 1 mL recommended dose of Symbioflor 2 yielded an arithmetic mean of 5.0 log 10 MPN E. coli (95% CI 4.6–5.2), and the geometric mean is 4.8 log 10 MPN E. coli (95% CI 4.6–4.9). A comparison of products with their respective product labels is shown in Figure 1. E. coli numbers in both products were approximately 2 orders
