  • 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

  • Skin Bacteria Help Cancer Cells Grow
    Our skin is covered in millions of bacteria and most of them help keep us healthy. However, for patients with lymphoma, it may be a rather different story, as new research from the University of Copenhagen shows that toxins in the staphylococcus bacteria help cancer cells ...More

  • Bacillus cereus is Able to Resist Certain Antibiotic Therapies
    The bacterium B. cereus had so far been considered to be exclusively endospore-forming. In response to harsh conditions, the bacteria form protective endospores enabling them to remain dormant for extended periods. When conditions are more favorable, the endospores ...More

  • Bacteria Battle: How One Changes Appearance, Moves Away to Resist the Other
    Two types of bacteria found in the soil have enabled scientists at Texas A&M AgriLife Research to get the dirt on how resistance to antibiotics develops along with a separate survival strategy. The study, published in the journal PLOS Genetics this month, identifies an ...More

  • Research Reveals How Bacterial Predators Kill Other Bugs Without Killing Themselves
    New research has revealed how a potentially useful predatory bacterium called Bdellovibrio protects itself against its own weapons when it invades other bacteria. The study by the labs of professor Liz Sockett and Dr. Andrew Lovering at the Universities of Nottingham and ...More
