Nonpathogenic Escherichia coli strain Nissle 1917 (O6:K5:H1) is used as a probiotic agent in medicine, mainly for the treatment of various gastroenterological diseases. To gain insight on the genetic level into its properties of colonization and commensalism, this strain's genome structure has been analyzed by three approaches: (i) sequence context(More)
BACKGROUND Probiotics are effective in inflammatory bowel diseases. Clinical effectiveness and dose dependency of E. coli Nissle (EcN) enemas were investigated in ulcerative colitis (UC). METHODS In a double-blind study, 90 patients with moderate distal activity in UC were randomly assigned to treatment with either 40, 20, or 10 ml enemas (N = 24, 23, 23)(More)
BACKGROUND Controversy still surrounds the question whether yeasts found in the gut are causally related to disease, constitute a health hazard, or require treatment. METHODS The authors present the state of knowledge in this area on the basis of a selective review of articles retrieved by a PubMed search from 2005 onward. The therapeutic recommendations(More)
In this paper we describe a new parallel tabu search heuristic for the vehicle routing problem with time window constraints (VRPTW). The neighborhood structure we propose is based on simple customer shifts and allows to consider infeasible interim-solutions. Similar to the column generation approach used in exact algorithms , all routes generated by the(More)
Structural analysis of lipopolysaccharide (LPS) isolated from semirough, serum-sensitive Escherichia coli strain Nissle 1917 (DSM 6601, serotype O6:K5:H1) revealed that this strain's LPS contains a bisphosphorylated hexaacyl lipid A and a tetradecasaccharide consisting of one E. coli O6 antigen repeating unit attached to the R1-type core. Configuration of(More)
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 interference of E. coli strain Nissle 1917 with Salmonella(More)
BACKGROUND Administering probiotics can prevent or cure some forms of diarrhea. The efficacy of probiotic Escherichia coli Nissle 1917 (EcN) in infants and toddlers with diarrhea >4 days was tested by a double-blind trial. METHODS One hundred fifty-one children aged 1-47 months with nonspecific diarrhea were randomized to receive either EcN suspension (N(More)
In most cases, acute diarrhoea will become self-limiting during the first few days after onset. For young children, however, health risks may develop when the disease lasts longer than 3 days. The purpose of the present trial was to determine whether the stool frequency of infants and toddlers suffering from acute diarrhoea could be normalised more quickly(More)
PCR was used to establish a specific detection system for the non-pathogenic Escherichia coli strain Nissle 1917 (DSM6601), which is used as a probiotic drug against intestinal disorders and diseases. Five PCR assays have been developed which are based on the chromosomally encoded major fimbrial subunit genes fimA (type 1 fimbriae) and focA (F1C fimbriae),(More)
