  • 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

  • Mothers Can Pass Traits to Offspring Through Bacteria's DNA
    It's a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents' DNA. But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown ...More

  • Scientists Take First X-ray Portraits of Living Bacteria at the LCLS
    Researchers working at the Department of Energy’s SLAC National Accelerator Laboratory have captured the first X-ray portraits of living bacteria. This milestone, reported in the Feb. 11 issue of Nature Communications, is a first step toward possible X-ray ...More

  • Researchers Discover How Bacteria Coordinate the Timing and Location of Subcellular Processes
    Not unlike an urban restaurant, the success of a bacterial cell depends on three things: localization, localization and localization. But the complete set of controls by which bacteria control the movement of proteins and other essential biological materials globally within ...More

  • Scientists Study Bacterial Adaptive Defenses
    Bacteria have a sophisticated means of defending themselves, and they need it: more viruses infect bacteria than any other biological entity. Two experiments undertaken at the Department of Energy's SLAC National Accelerator Laboratory provide new insight at the heart of ...More

  • New Bacterial Language is Discovered
    Bacteria communicate by means of chemical signals and can develop common characteristics through this "agreement" and also develop their potential pathogenic effects in this way. Scientists working with Dr. Helge B. Bode, an Merck-endowed professor for molecular ...More
