• Biofilms - an invisible threat to food safety
  

  Biofilms are potential sources of contamination in the food industry. A recent study by the FFoQSI Competence Center at the Vetmeduni Vienna investigated where they hide and what bacteria can be found in them. Biofilms can cause additional costs in production and are a source of danger to consumer h more

• The discovery of ancient Salmonella
  

  Using Salmonella enterica genomes recovered from human skeletons as old as 6,500 years, an international team of researchers illustrates the evolution of a human pathogen and provides the first ancient DNA evidence in support of the hypothesis that the cultural transition from foraging to farming fa more

• Magnesium deprivation stops pathogen growth
  

  When pathogens invade the cells, our body combats them using various methods. Researchers at the University of Basel’s Biozentrum have now been able to show how a cellular pump keeps such invading pathogens in check. As the researchers report in “Science”, this pump causes a magnesium shortage, whic more

• Growth of Campylobacter using BMG LABTECH’s FLUOstar Omega equipped with ACU
  

  Growth of the fastidious microorganism Campylobacter jejuni was monitored using a FLUOstar Omega microplate reader equipped with the Atmospheric Control Unit (ACU) for independent control of oxygen and carbon dioxide. Growth was found tob e optimal a more

The Chemistry of Cocktail Spherification

Here’s the second in the series of graphics I’ve produced for my Pint of Science event at La Raza Cambridge (UK) in a few weeks’ time. Today’s graphic looks at how chemistry can help to make caviar and spheres in cocktails, and the chemical agents used to do it. more

• CRP-cAMP mediates silencing of Salmonella virulence at the post-transcriptional level

  by Youssef El Mouali, Tania Gaviria-Cantin, María Antonia Sánchez-Romero, Marta Gibert, Alexander J. Westermann, Jörg Vogel, Carlos Balsalobre Invasion of epithelial cells by Salmonella enterica requires expression of genes located in the pathogenicity island I (SPI-1). The expression of SPI-1 ge more

• A cell-based infection assay identifies efflux pump modulators that reduce bacterial intracellular load

  by Abigail L. Reens, Amy L. Crooks, Chih-Chia Su, Toni A. Nagy, David L. Reens, Jessica D. Podoll, Madeline E. Edwards, Edward W. Yu, Corrella S. Detweiler Bacterial efflux pumps transport small molecules from the cytoplasm or periplasm outside the cell. Efflux pump activity is typically increase more

• Endostatin gene therapy delivered by attenuated Salmonella typhimurium in murine tumor models

  Salmonella typhimurium (hereafter S. typhimurium), as Gram-negative facultative anaerobic bacteria, are good candidates for cancer therapy and delivering therapeutic antitumor agents. However, it is necessary to reduce the virulence of such bacteria and enhance their tumor-targeting ability, and the more
