  • 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

  • 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

  • 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

  • Tiny DNA Pyramids Enter Bacteria Easily and Deliver a Deadly Payload
    Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics — and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA ...More
