  • Gut Bacteria's Collection of Genomes is Unique, Remains Stable Over Time
    We all have E. coli bacteria in our gut but each of us carries a version that is genetically slightly different. The same can be said of most gut microbes: our own gut metagenome, that is the sum of all the genomes of all our gut microbes, appears to be really specific to ...More

  • 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

  • Microban Research Finds Nearly 5 Million Bacteria on Single Wet Razor Handle
    Nearly 5 million bacteria have been found on a single disposable wet razor handle in new laboratory research by Microban. As comparisons, typical levels of bacteria on household objects include 50 colony forming units per square inch on a computer mouse, 214 on microwave ...More

  • Filming Bacterial Life in Multicolor is a New Diagnostic and Antibiotic Discovery Tool
    An international team of scientists led by Indiana University chemist Michael S. VanNieuwenhze and biologist Yves Brun has discovered a revolutionary new method for coloring the cell wall of bacterial cells to determine how they grow, in turn providing a new, much-needed ...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

  • Sinusitis Linked to Microbial Diversity
    A common bacteria ever-present on the human skin and previously considered harmless, may, in fact, be the culprit behind chronic sinusitis, a painful, recurring swelling of the sinuses that strikes more than 1 in 10 Americans each year, according to a study by scientists at ...More
