  • UMass Amherst Research Advances Understanding of How Bacteria Communicate
    Bacteria have traditionally been viewed as solitary organisms that "hang out on their own," says molecular biologist Kevin Griffith of the University of Massachusetts Amherst. However, scientists now realize that in fact, bacteria exhibit social behavior within groups. As ...More

  • Researchers Find That Microbes are 'Scared to Death' by Virus Presence
    The microbes could surrender to the harmless virus, but instead freeze in place, dormant, waiting for their potential predator to go away, according to a recent study in mBio. University of Illinois researchers found that Sulfolobus islandicus can go dormant, ceasing to ...More

  • Common Bacteria on the Verge of Becoming Antibiotic-Resistant Superbugs
    Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at Washington University School of Medicine in St. Louis. The study shows that two genes that confer ...More

  • Modifying Bacterial Lipids Can Label and Target Bacteria, Spare Healthy Cells
    Targeting deadly, drug-resistant bacteria poses a serious challenge to researchers looking for antibiotics that can kill pathogens without causing collateral damage in human cells. A team of Boston College chemists details a new approach using a "warhead" molecule to attack ...More

  • Link Identified Between Virus Recognition, Destruction in Bacterial Immune System
    An immune system that helps bacteria combat viruses is yielding unlikely results such as the ability to edit genome sequences and potentially correct mutations that cause human disease. University of Georgia researchers Michael and Rebecca Terns were among the first to ...More

  • Virus-Cutting Enzyme Helps Bacteria Remember a Threat
    Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order ...More

  • Bacteria Connect to Each Other and Exchange Nutrients
    Bacteria usually live in species-rich communities and frequently exchange nutrients and other metabolites. Until now, it was unclear whether microorganisms exchange metabolites exclusively by releasing them into the surrounding environment or whether they also use direct ...More

  • Researchers Study the Influence of Host Organisms on Bacterial Metabolism
    Monika Ehling-Schulz's group from the Institute of Microbiology, together with Mathias Müller's group at the Institute of Animal Breeding and Genetics studied the influence of host organisms on bacterial metabolism. The researchers infected three different lineages of ...More

  • Mutant Bacteria That Keep on Growing
    The typical Escherichia coli, the laboratory rat of microbiology, is a tiny 1-2 thousandths of a millimeter long. Now, by blocking cell division, two researchers at Concordia University in Montreal have grown E. coli that stretch three quarters of a millimeter. That's up to ...More

  • Forgotten Bacterium is the Cause of Many Severe Sore Throats in Young Adults
    New research from the University of Alabama at Birmingham suggests that Fusobacterium necrophorum more often causes severe sore throats in young adults than streptococcus — the cause of the much better known strep throat. The findings, published today in the Annals of ...More
