  • Images Reveal Bacterial Motor Parts in Unprecedented Detail
    Many bacteria swim using flagella -- long tails that are attached to tiny motors made of proteins, just tens of nanometres wide. These motors spin the flagella, which work as nanoscale propellers to drive the bacterium forward. ...More

  • Capsule Shedding: A New Bacterial Pathway That Promotes Invasive Disease
    St. Jude Children's Research Hospital scientists have identified an enzyme that acts early in pneumococcal infections to promote bacterial survival and invasive disease by removing the bacteria's capsule. The research appears today in the scientific journal Nature ...More

  • Scientists Pave the Way for a New Generation of Superbug Drugs
    New research published today in the journal Nature reveals the mechanism by which drug-resistant bacterial cells maintain a defensive barrier. The findings pave the way for a new wave of drugs that kill superbugs by bringing down their defensive walls rather than attacking ...More

  • A New Way of Fighting Bacteria?
    In bacteria, toxin-antitoxin systems consist of a set of two closely linked genes. Situated on the same chromosome, they encode both a protein "poison" and a counteracting "antidote." Under normal conditions, the antitoxin protein binds the toxin protein and prevents it ...More

  • What Makes a Bacterial Species Able to Cause Human Disease?
    An international team of scientists, led by researchers at University of California, San Diego School of Medicine and the J. Craig Venter Institute (JCVI), have created the first comprehensive, cross-species genomic comparison of all 20 known species of Leptospira, a ...More

  • Alcohol Also Damages the Liver by Allowing Bacteria to Infiltrate
    Alcohol itself can directly damage liver cells. Now researchers at University of California, San Diego School of Medicine report evidence that alcohol is also harmful to the liver for a second reason — it allows gut bacteria to migrate to the liver, promoting ...More

  • Scientists Study How Bacterial Communication Causes Infection, Blockage
    The destructive ability of bacteria to organize an infection or block pathways such as intestines, medical stents and wastewater pipes relies on communication with one another. New work from Princeton University researchers shows that the effectiveness of bacteria's ability ...More

  • ASU Scientists Discover How Blue and Green Clays Kill Bacteria
    Since prehistoric times, clays have been used by people for medicinal purposes. Whether by eating it, soaking in a mud bath, or using it to stop bleeding from wounds, clay has long been part of keeping humans healthy. Certain clays have also been found with germ-killing ...More

  • Commensal Bacteria Regulate Immune Cells in Lungs to Produce Proteins for Host Defense
    Microbiota, the trillions of bacteria that co-exist in the body, regulate the ability of lung dendritic cells to generate immune responses, according to a study led by researchers from the Icahn School of Medicine at Mount Sinai, published online in the Journal of ...More
