  • How Bacteria Battle Fluoride
    Researchers have determined key structural differences that allow a subset of CLC transporters to preferentially select fluoride over chloride, which can help bacteria expel toxic fluoride. The binding site of a standard CLC transporter is shown here. He’s not a ...More

  • Bacteria Harbor Secret Weapons Against Antibiotics
    The ability of pathogenic bacteria to evolve resistance to antibiotic drugs poses a growing threat to human health worldwide. And scientists have now discovered that some of our microscopic enemies may be even craftier than we suspected, using hidden genetic changes to ...More

  • Targeting the Protein-Making Machinery to Stop Harmful Bacteria
    One challenge in killing off harmful bacteria is that many of them develop a resistance to antibiotics. Researchers at the University of Rochester are targeting the formation of the protein-making machinery in those cells as a possible alternate way to stop the bacteria. ...More

  • Smelly Clothes? Blame it on the Bacteria
    Polyester clothes smell worse than cotton, following intensive exercise by their wearers, because bacteria that cause odor grow better on polyester, according to research published ahead of print in the journal Applied and Environmental Microbiology. In the study, the ...More

  • Discovery Reveals How Bacteria Distinguish Harmful Versus Helpful Viruses
    When they are not busy attacking us, germs go after each other. But when viruses invade bacteria, it doesn’t always spell disaster for the infected microbes: Sometimes viruses actually carry helpful genes that a bacterium can harness to, say, expand its diet or better ...More

  • Harnessing the Power of Bacteria's Sophisticated Immune System
    Bacteria’s ability to destroy viruses has long puzzled scientists, but researchers at the Johns Hopkins Bloomberg School of Public Health say they now have a clear picture of the bacterial immune system and say its unique shape is likely why bacteria can so quickly ...More

  • Study Suggests Bacteria Help Program Metabolic Development
    A new study published today in Cell suggests that antibiotic exposure during a critical window of early development disrupts the bacterial landscape of the gut, home to trillions of diverse microbes, and permanently reprograms the body’s metabolism, setting up a ...More

  • Social Networking is Key to Helping Bugs Spread, Study Shows
    Fresh discoveries about how bacteria co-operate with each other when causing infection could help scientists identify animal diseases that might transmit to people. Bugs that can co-operate best with each other are most likely to be able to jump to new species, including ...More

  • Ancient Genetic Material from Caries Bacterium Obtained for the First Time
    UAB research concludes that the Streptococcus mutans, one of the principal bacteria causing dental caries, has increased the changes in its genetic material over time, possibly coinciding with dietary changes linked to the expansion of humanity. This is highlighted in ...More

  • Protein's 'Hands' Enable Bacteria to Establish Infection, Research Finds
    When it comes to infecting humans and animals, bacteria need a helping hand. Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven ...More
