Electronic address: wangzx@ciac.ac.cn.AbstractHerein, a three-dimensional carbohydrate modified polyacrylamide hydrogel microarray (3D carbohydrate hydrogel microarray) has been fabricated and employed as micro-reactor for capturing Escherichia coli (E. coli) by multivalent binding of concanavalin A (Con A) with O-antigen on the cellular surface of E. coli and immobilized monosaccharides on hydrogel spot, and the interactions of type 1 fimbriae of E. coli with immobilized monosaccharides. Because of the transparent performance of polyacrylamide hydrogel, the captured E. coli can be directly observed by a conventional microscope under a bright-field mode. The experimental result demonstrates that α-D-mannopyranoside (Man-α) modified hydrogel surface shows high efficiency of E. coli capturing. The 3D Man-α hydrogel microarray-based assay shows reasonable low detection limit (1.0×10(4) cells/mL) and large dynamic range (1.0×10(5) to 1.0×10(9)cells/mL) for detecting E. coli. In addition, bacterial adhesion inhibition assay has been demonstrated by the interactions of E. coli with ten saccharides, and satisfactory results have been obtained.

- Cyclic-AMP inhibition of fimbriae and prodigiosin production by Serratia marcescens is strain-dependent.
- Stella NA1, Shanks RM.Author information 1Charles T. Campbell Laboratory of Ophthalmic Microbiology, Department of Ophthalmology, University of Pittsburgh, Pittsburgh, PA, 15213, USA, stellan@upmc.edu.AbstractThe cyclic-nucleotide 3',5'-cyclic AMP (cAMP) is an ancient and widespread regulatory molecule. Previous studies have shown that fimbria production and secondary metabolite production are inhibited by cAMP in the prokaryote Serratia marcescens. This study used genetic manipulations to test the strain specificity of cAMP-cyclic-AMP receptor protein regulation of fimbria production and of the red pigment, prodigiosin. A surprising amount of variation was observed, as multicopy expression of the cAMP-phosphodiesterase gene, cpdS, conferred either an increase or decrease in fimbriae-dependent yeast agglutination and prodigiosin production depending upon the strain background. Mutation of crp, the gene coding for the cAMP-receptor protein, similarly conferred strain-dependent phenotypes. This study shows that three distinct biological properties, modulated by a conserved genetic regulatory molecule, can vary significantly among strains. Such variation can complicate the functional analysis of bacterial phenotypic properties which are dependent upon global genetic regulators such as cAMP.

- Role of F1C Fimbriae, Flagella, and Secreted Bacterial Components in the Inhibitory Effect of Probiotic Escherichia coli Nissle 1917 on Atypical Enteropathogenic E. coli Infection.
- Kleta S1, Nordhoff M, Tedin K, Wieler LH, Kolenda R, Oswald S, Oelschlaeger TA, Bleiß W, Schierack P.Author information 1Zentrum für Infektionsmedizin, Institut für Mikrobiologie und Tierseuchen, Fachbereich Veterinärmedizin, Freie Universität Berlin, Berlin, Germany.AbstractEnteropathogenic Escherichia coli (EPEC) is recognized as an important intestinal pathogen that frequently causes acute and persistent diarrhea in humans and animals. The use of probiotic bacteria to prevent diarrhea is gaining increasing interest. The probiotic E. coli strain Nissle 1917 (EcN) is known to be effective in the treatment of several gastrointestinal disorders. While both in vitro and in vivo studies have described strong inhibitory effects of EcN on enteropathogenic bacteria, including pathogenic E. coli, the underlying molecular mechanisms remain largely unknown. In this study, we examined the inhibitory effect of EcN on infections of porcine intestinal epithelial cells with atypical enteropathogenic E. coli (aEPEC) with respect to single infection steps, including adhesion, microcolony formation, and the attaching and effacing phenotype. We show that EcN drastically reduced the infection efficiencies of aEPEC by inhibiting bacterial adhesion and growth of microcolonies, but not the attaching and effacing of adherent bacteria. The inhibitory effect correlated with EcN adhesion capacities and was predominantly mediated by F1C fimbriae, but also by H1 flagella, which served as bridges between EcN cells. Furthermore, EcN seemed to interfere with the initial adhesion of aEPEC to host cells by secretion of inhibitory components. These components do not appear to be specific to EcN, but we propose that the strong adhesion capacities enable EcN to secrete sufficient local concentrations of the inhibitory factors. The results of this study are consistent with a mode of action whereby EcN inhibits secretion of virulence-associated proteins of EPEC, but not their expression.
