(Submitter supplied) The foodborne pathogen Listeria monocytogenes uses a number of transcriptional regulators, including the negative regulator HrcA, to control gene expression under different environmental conditions and in response to stress. Gene expression patterns of DhrcA stationary phase cells were compared to wt to identify hrcA-dependent genes. We identified 61 HrcA-dependent genes that showed significant expression ratios (adj. more...

(Submitter supplied) To characterize regulons of alternative sigma factor SigH, SigL, and SigC in Listeria monocytogenes, in-frame mutant strains were created in the 10403S background. Regulons controlled by these 3 alternative sigma factors were characterized by whole-genome microarrays. The L. monocytogenes 10403S wild type and sigma factor null mutation strains were grown at 37 °C to stationary phase (defined in this study as growth to OD600 = 1.0, followed by incubation for an additional 3 h) prior to RNA isolation. more...

(Submitter supplied) The bacterial cell envelope is a complex, multilayered structure that is not only essential to maintain cellular integrity, but also facilitates vital bacterial processes such as adaption, colonization and adhesion. Cell envelopes comprise a wide range of molecules, such as proteins and capsular polysaccharide (CPS), which collectively decorate the bacterial cell in a species- and strain specific manner. more...

(Submitter supplied) Survival of the foodborne pathogen Listeria monocytogenes in acidic environments (e.g., stomach and low pH foods) is vital to its transmission. L. monocytogenes grows at temperatures as low as 2°C, and refrigerated, ready-to-eat foods have been sources of L. monocytogenes outbreaks. The purpose of this study was to determine whether growth at a low temperature (i.e., 7°C) affects the response of L. monocytogenes to sudden acid shock.

(Submitter supplied) Whole genome transcriptional profiling was used to characterize the response of Lactobacillus plantarum WCFS1 human isolate during challenge with 1.5 mM gallic acid (GA). Twelve independent experiments were performed and mixed at random in groups of four for total of three RNA samples. The transcriptional profile reveals a massive induction of genes involved in transport and decarboxilation of gallic acid.

(Submitter supplied) Sortases are transpeptidase enzymes that couple surface proteins to the peptidoglycan of Gram-positive bacteria. Several sortase-dependent proteins (SDPs) have been identified that are crucial for bacterial pathogenesis and, although less frequently, for the physiology of non-pathogenic bacteria. We found that an isogenic sortase A (srtA) deletion derivative (NZ7104) of Lactobacillus plantarum WCFS1 did not express any residual SrtA activity, i.e. more...

(Submitter supplied) Analyses of the Wild type and the sigma 54 mutant strain NZ7306 with and without peroxide treatment: A Lactobacillus plantarum strain with a deletion in the alternative sigma factor 54 (?54) encoding gene rpoN, displayed a 100 fold higher sensitivity to peroxide as compared to its parental strain. This feature could be due to ?54-dependent regulation of genes involved in peroxide stress response. However, transcriptome analyses of the wild type and the mutant strain during peroxide exposure did not support such a role for ?54. more...

However, there is little information on the mechanisms whereby prebiotics exert their specific effects upon such microorganisms. To study the genomic basis of scFOS metabolism in Lactobacillus plantarum WCFS1, two-colour microarrays were used to screen for differentially expressed genes when grown on scFOS as compared to glucose (not a prebiotic). more...
