Background: The probiotic bacterial strain Escherichia coli Nissle 1917 (EcN) is used for the treatment of ulcerative colitis (UC), diarrhea and constipation. Its beneficial effects in the treatment of UC have been demonstrated in several controlled clinical studies; however, the mechanism of action on the cellular level is still not completely clear. One probiotic, Escherichia coli Nissle (Mutaflor, Ardeypharm), is a nonpathogenic strain of E. coli that has been shown to be effective for both inducing remission in patients who have UC and maintaining remission for at least 1 year. Researchers have compared E. coli Nissle to mesalamine, which is the standard treatment for UC, and in a number Purpose: SYNB1891 is a live, modified strain of the probiotic Escherichia coli Nissle 1917 (EcN) engineered to produce cyclic dinucleotides under hypoxia, leading to STimulator of INterferon Genes (STING) activation in phagocytic antigen-presenting cells in tumors and activating complementary innate immune pathways. The aim of this study was to improve our understanding of the E. coli Nissle 1917-host interaction by analyzing the gene expression pattern initiated by this probiotic in human intestinal epithelial cells. Methods: Gene expression profiles of Caco-2 cells treated with E. coli Nissle 1917 were analyzed with microarrays. A second human intestinal Herein, we have engineered Escherichia. coli Nissle 1917 to produce and secrete three antimicrobial peptides, Enterocin A, Enterocin B, and Hiracin JM79, to specifically target and kill Enterococcus. These peptides exhibited potent activity against both Enterococcus faecium and Enterococcus faecalis , the two most prominent species responsible Subsequently, an anaerobic inducible expression vector was constructed under Vitreoscilla hemoglobin gene promoter Pvhb in E. coli Nissle 1917 (EcN). The secretory expression of Tum-5 in the engineered bacterium was determined in vitro and in vivo by Western blot or immunochemistry. A robust colonizer of the human gastrointestinal tract, Escherichia coli Nissle 1917, is widely employed in probiotic therapy. In this study, we performed a genetic screen to identify genes that are involved in Nissle biofilm formation. We found that F1C fimbriae are required for biofilm formation on an inert surface. Escherichia coli Nissle 1917 (EcN) is a probiotic used in the treatment of intestinal diseases. Although it is considered safe, EcN is closely related to the uropathogenic E. coli strain CFT073 and contains many of its predicted virulence elements. Thus, it is relevant to assess whether virulence-associated genes are functional in EcN.

Pharmaceutics. 2021. Free PMC article Abstract Highly efficient drug delivery systems with excellent tumor selectivity and minimal toxicity to normal tissues remain challenging for tumor treatment. Although great effort has been made to prolong the blood circulation and improve the delivery efficiency to tumor sites, nanomedicines are rarely approved for clinical application. Bacteria have the inherent properties of homing to solid tumors, presenting themselves as promising drug delivery systems. Escherichia coli Nissle 1917 (EcN) is a commonly used probiotic in clinical practice. Its facultative anaerobic property drives it to selectively colonize in the hypoxic area of the tumor for survival and reproduction. EcN can be engineered as a bacteria-based microrobot for molecular imaging, drug delivery, and gene delivery. This review summarizes the progress in EcN-mediated tumor imaging and therapy and discusses the prospects and challenges for its clinical application. EcN provides a new idea as a delivery vehicle and will be a powerful weapon against cancer.

W większości to nieszkodliwe bakterie, niektóre jednak powodować mogą poważne zatrucia pokarmowe, zapalenia żołądka, czy jelit. Jest jednak jeden wyjątkowy szczep, który stosuje się do zapobiegania i leczenia wszelkich dolegliwości trawiennych – Escherichia coli Nissle 1917. Bakterie te zostały odkryte ponad 100 lat temu, przez fryburskiego higienistę, prof. dr Alfreda Nissle, który założył we Freiburgu w 1938 r. prywatny instytut badań bakteriologicznych, którym kierował aż do śmierci w 1965 r. Podczas I wojny światowej, w 1917 roku, w pewnej grupie żołnierzy, w szpitalu wojskowym nieopodal Freiburga, wybuchła czerwonka. Tylko jeden żołnierz pozostał zdrowy, nie wykazując żadnych objawów choroby jelit. Widząc to, prof. Nissle przebadał jego kał pod kątem zawartości bakterii jelitowych i wyizolował szczep E. coli, który następnie użył do leczenia pozostałych żołnierzy. Od tego czasu, szczep ten zaczęto nazwać E. coli Nissle 1917, i stosować go w leczeniu różnych zaburzeń żołądkowo-jelitowych. Na Uniwersytecie we Freiburgu, studenci prof. Nissle, podczas zajęć praktycznych z mikrobiologii, mieszali własne próbki kału z czystymi hodowlami patogennych szczepów Salmonelli. Zazwyczaj obserwowali szybki rozrost Salmonelli, wypierających tym samym, inne bakterie jelitowe. Były jednak i takie przypadki, w których rozrost był nieznaczny, a nawet wcale niezauważalny. W ten sposób powstała hipoteza, że mikroflora niektórych próbek kału zawiera takie szczepy, które hamują rozwój mikroorganizmów patogennych. Później podejrzenia te zostały potwierdzone w laboratorium, w trakcie badań hodowli mieszanin szczepów Salmonella z różnymi izolatami E. coli, uzyskanymi z próbek kału zdrowych ludzi. Okazało się, że patogenne szczepy E. coli posiadają dodatkowe geny, tzw. „geny zjadliwości”, które czynią je chorobotwórczymi. Escherichia coli Nissle 1917 natomiast, wyróżnia się na tle innych bakterii ze swojej rodziny, tym, że na drodze ewolucji, poprzez poziomy transfer genów z innych bakterii jelitowych, nabyła dodatkowe elementy genetyczne, nazywane „Wyspami Genomowymi”. To one są odpowiedzialne m. in. za zdolność hamowania rozwoju różnego rodzaju enteropatogenów. Tę szczególną właściwość, prof. Nissle nazwał „aktywnością antagonistyczną”. Niepatogenny szczep bakterii Escherichia coli wykazuje wiele korzystnych właściwości, pełni istotne funkcje w ludzkim organizmie. Odpowiedzialny jest za rozkład produktów spożywczych, bierze udział w produkcji witamin z grupy B i K, poprawia wchłanianie żelaza. Jest bakterią tlenową, więc po przez zużycie tlenu obecnego w jelitach przyczynia się do wytworzenia pozytywnego środowiska dla anaerobów – bakterii beztlenowych. Wspomaga proces zasiedlania innych bakterii probiotycznych jednocześnie usuwając patogeny z mikroflory jelit. Szczep E-coli Nissle 1917 posiada właściwości probiotyczne oraz adhezyjne – przyczepia się do ścian jelitowych uszczelniając je i wpływając aprobująco na wchłanianie organizmu. Szczep Escherichia coli Nissle 1917 sprzyja tworzeniu substancji przeciwzapalnych i autogennych antybiotyków oraz wpływa pozytywnie na system immunologiczny. Niepatogenna E-coli sprawdza się w leczeniu wrzodziejącego zapalenia jelita grubego, zespołu jelita drażliwego, w walce z alergiami pokarmowymi, a także wykazuje korzystne działanie w profilaktyce raka jelita grubego. Niedobór tej bakterii w organizmie przynieść może przykre skutki w postaci częstego występowania nawracających infekcji moczowo-płciowych, czy oddechowych, a to wszystko za sprawą obniżonej odporności śluzówek. Niestety, wraz z pojawieniem się antybiotyków, zgasło zainteresowanie mikroflorą jelitową i terapeutycznym zastosowaniem żywych bakterii. Dopiero niedawno, medyczne osiągnięcia i rozwój mikrobiologii, spowodowały, że wcześniejsze doświadczenia mogły zostać dokładnie potwierdzone, a leczenie probiotykami znalazło się na powrót w centrum zainteresowania lekarzy i naukowców. Obecnie jest to prawdopodobnie najintensywniej badany szczep bakteryjny.

AbstractBackgroundGenetically modified probiotics have potential for use as a novel approach to express bioactive molecules for the treatment of obesity. The objective of the present study was to investigate the beneficial effect of genetically modified Escherichia coli Nissle 1917 (EcN-GM) in obese C57BL/6J an obesity model in C57BL/6J mice was successfully established. Then, the obese mice were randomly assigned into three groups: obese mice (OB), obese mice + EcN-GM (OB + EcN-GM), and obese mice + orlistat (OB + orlistat) (n = 10 in each group). The three groups were gavaged with ml of 1010 CFU/ml control EcN, EcN-GM (genetically engineered EcN) and 10 ml/kg orlistat. Body weight, food consumption, fat pad and organ weight, hepatic biochemistry and hepatic histopathological alterations were measured. The effects of EcN-GM on the levels of endocrine peptides and the intestinal microbiota were also supplementation for 8 weeks, EcN-GM was associated with decreases in body weight gain, food intake, fat pad and liver weight, and alleviation hepatocyte steatosis in obese mice. EcN-GM also increased the level of GLP-1 in serum and alleviated leptin and insulin resistance. Moreover, supplementation with EcN-GM increased the α-diversity of the intestinal microbiota but did not significantly influence the relative abundance of Firmicutes and results indicated that EcN-GM, a genetically modified E. coli strain, may be a potential therapeutic approach to treat obesity. The beneficial effect of EcN-GM may be independent of the alteration of the diversity and composition of the intestinal microbiota in obese mice.
