• Antimicrobial resistance is drastically rising
  

  An international team of researchers led by ETH has shown that antimicrobial-resistant infections are rapidly increasing in animals in low and middle income countries. They produced the first global of resistance rates, and identified regions where interventions are urgently needed. The world is exp more

• Resistance can spread even without the use of antibiotics
  

  Antibiotic resistance does not spread only where and when antibiotics are used in large quantities, ETH researchers conclude from laboratory experiments. Reducing antibiotic use alone is therefore not sufficient to curtail resistance, and should be done in conjunction with measures to prevent infect more

• For salmonella detection, genomic tool emerges as a key

  The world's food supply will become safer as the food industry shifts to high-resolution, whole-genome sequencing - which examines the full DNA of a given organism all at once. This move to make sequencing ubiquitous will lead to the consistently reliable detection of salmonella. A paper published i 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
