  • Bacteria Hijack Host Cell Process, Create Their Own Food Supply to Become Infectious
    Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found. This bacterium, Anaplasma phagocytophilum (Ap), secretes a protein ...More

  • Engineered Bacteria Sacrifice Themselves for the Good of the Bacterial Population
    Scientists have engineered bacteria that are capable of sacrificing themselves for the good of the bacterial population. These altruistically inclined bacteria, which are described online in the journal Molecular Systems Biology, can be used to demonstrate the conditions ...More

  • New Type of Bacterial Protection Found Within Cells
    UC Irvine biologists have discovered that fats within cells store a class of proteins with potent antibacterial activity, revealing a previously unknown type of immune system response that targets and kills bacterial infections. Steven Gross, UCI professor of developmental ...More

  • Researchers Discover How Bacteria Talk to Each Other and Our Cells
    Bacteria can talk to each other via molecules that they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Linköping University in Sweden are showing how bacteria control processes in human cells ...More

  • Viruses Help Scientists Battle Pathogenic Bacteria and Improve Water Supply
    Infectious bacteria received a taste of their own medicine from University of Missouri researchers who used viruses to infect and kill colonies of Pseudomonas aeruginosa, common disease-causing bacteria. The viruses, known as bacteriophages, could be used to efficiently ...More

  • X-rays Reveal the Self-Defense Mechanisms of Bacteria
    A research group at Aarhus University has gained unique insight into how bacteria control the amount of toxin in their cells. The new findings can eventually lead to the development of novel forms of treatment for bacterial infections. Many pathogenic bacteria are able to ...More
