  1. Regulated intramembrane proteolysis of the virulence activator TcpP in Vibrio cholerae is initiated by the tail-specific protease (Tsp)

    • Molecular Microbiology
    • Vibrio cholerae uses a multiprotein transcriptional regulatory cascade to control expression of virulence factors cholera toxin and toxin-coregulated pilus. Two proteins in this cascade are ToxR and TcpP – unusual membrane-localized transcription factors with relatively undefined periplasmic domains and transcription activator cytoplasmic domains.

  2. Periplasmic superoxide dismutase SodCI of Salmonella binds peptidoglycan to remain tethered within the periplasm

    • Molecular Microbiology
    • Salmonellae survive and propagate in macrophages to cause serious systemic disease. Periplasmic superoxide dismutase plays a critical role in this survival by combating phagocytic superoxide. Salmonella Typhimurium strain 14028 produces two periplasmic superoxide dismutases, SodCI and SodCII. Although both proteins are produced during infection, only SodCI is functional in the macrophage phagosome.

  3. Delineation of genetic relatedness and population structure of oral and enteric Campylobacter concisus strains by analysis of housekeeping genes [STANDARD]

    • Microbiology
    • Campylobacter concisus is an oral bacterium that has been shown to be associated with inflammatory bowel disease (IBD). In this study we examined clusters of oral C. concisus strains isolated from patients with IBD and healthy controls by analysing the six housekeeping genes that we previously described. In addition, we investigated the population structure of C. concisus strains.

    • Eurosurveillance
    • A multinational outbreak of salmonellosis linked to the Riga Cup 2015 junior ice-hockey competition was detected by the Finnish health authorities in mid-April and immediately notified at the European Union level. This prompted an international outbreak investigation supported by the European Centre for Disease Prevention and Control. As of 8 May 2015, seven countries have reported 214 confirmed and suspected cases, among which 122 from Finland.

    • Journal of Food Science
    • Ultraviolet lightUV) has antimicrobial effects, but the shadowing effect has limited its application. In this study, a novel setup using UV processing in agitated water was developed to inactivate Escherichia coli O157:H7 and Salmonella on blueberries. Blueberries were dip- or spot-inoculated with E. coli or Salmonella. Blueberries inoculated with E. coli were treated for 2 to 10 min with UV directly (dry UV) or immersed in agitated water during UV treatment (wet UV). E.

  11. Genetic Diversity of the fliC Genes Encoding the Flagellar Antigen H19 of Escherichia coli and Application to the Specific Identification of Enterohemorrhagic E. coli O121:H19 [Food Microbiology]

    • Applied and Environmental Microbiology
    • Enterohemorrhagic Escherichia coli (EHEC) O121:H19 belong to a specific clonal type distinct from other classical EHEC and major enteropathogenic E. coli groups and is regarded as one of the major EHEC serogroups involved in severe infections in humans. Sequencing of the fliC genes associated with the flagellar antigen H19 (fliCH19) revealed the genetic diversity of the fliCH19 gene sequences in E. coli. A cluster analysis of 12 fliCH19 sequences, 4 from O121 and 8 from non-O121 E.

  12. Public Health Investigation of Two Outbreaks of Shiga Toxin-Producing Escherichia coli O157 Associated with Consumption of Watercress [Public and Environmental Health Microbiology]

    • Applied and Environmental Microbiology
    • An increase in the number of cases of Shiga toxin-producing Escherichia coli (STEC) O157 phage type 2 (PT2) in England in September 2013 was epidemiologically linked to watercress consumption. Whole-genome sequencing (WGS) identified a phylogenetically related cluster of 22 cases (outbreak 1). The isolates comprising this cluster were not closely related to any other United Kingdom strain in the Public Health England WGS database, suggesting a possible imported source.

  13. Nisin H Is a New Nisin Variant Produced by the Gut-Derived Strain Streptococcus hyointestinalis DPC6484 [Spotlight]

    • Applied and Environmental Microbiology
    • Accumulating evidence suggests that bacteriocin production represents a probiotic trait for intestinal strains to promote dominance, fight infection, and even signal the immune system. In this respect, in a previous study, we isolated from the porcine intestine a strain of Streptococcus hyointestinalis DPC6484 that displays antimicrobial activity against a wide range of Gram-positive bacteria and produces a bacteriocin with a mass of 3,453 Da.

  14. Two-Component-System Histidine Kinases Involved in Growth of Listeria monocytogenes EGD-e at Low Temperatures [Food Microbiology]

    • Applied and Environmental Microbiology
    • Two-component systems (TCSs) aid bacteria in adapting to a wide variety of stress conditions. While the role of TCS response regulators in the cold tolerance of the psychrotrophic foodborne pathogen Listeria monocytogenes has been demonstrated previously, no comprehensive studies showing the role of TCS histidine kinases of L. monocytogenes at low temperature have been performed. We compared the expression levels of each histidine kinase-encoding gene of L.

    • International Journal of Food Science & Technology
    • Raffinose family oligosaccharides (RFOs) content in Glycine max seed of cultivar Chiang Mai60, a local soybean of Thailand, was investigated. RFOs and other low molecular weight sugars were extracted by 50% (v/v) ethanol and quantified by high-performance liquid chromatography (HPLC). The prebiotic property of this extract was subsequently studied by in vitro method.

  25. Integrating small molecule signalling and H-NS antagonism in Vibrio cholerae, a bacterium with two chromosomes

    • Molecular Microbiology
    • H-NS is a well-established silencer of virulence gene transcription in the human pathogen Vibrio cholerae. Biofilm formation aids V. cholerae in colonizing both its host and its external environments and H-NS silences biofilm gene expression. Cyclic-di-guanosine monophosphate acts through the DNA binding proteins VpsR and VpsT to overcome H-NS-mediated repression of biofilm genes, driving a transition between a planktonic and a colonial/biofilm lifestyle.
