• Gingivitis Bacteria Manipulate Your Immune System So They Can Thrive in Your Gums
    A new research report published in the Journal of Leukocyte Biology shows how the bacteria known for causing gum disease--Porphyromonas gingivalis--manipulates the body's immune system to disable normal processes that would otherwise destroy it. Specifically, the report ...More

  • Study Says Bacterial Ecology Living on Humans Has Changed in the Last Century
    A University of Oklahoma-led study has demonstrated that ancient DNA can be used to understand ancient human microbiomes. The microbiomes from ancient people have broad reaching implications for understanding recent changes to human health, such as what good bacteria might ...More

  • Gut Bacteria's Collection of Genomes is Unique, Remains Stable Over Time
    We all have E. coli bacteria in our gut but each of us carries a version that is genetically slightly different. The same can be said of most gut microbes: our own gut metagenome, that is the sum of all the genomes of all our gut microbes, appears to be really specific to ...More

  • Bacteria Hijack Host Cell Process, Create Their Own Food Supply to Become Infectious
    Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found. This bacterium, Anaplasma phagocytophilum (Ap), secretes a protein ...More

  • Engineered Bacteria Sacrifice Themselves for the Good of the Bacterial Population
    Scientists have engineered bacteria that are capable of sacrificing themselves for the good of the bacterial population. These altruistically inclined bacteria, which are described online in the journal Molecular Systems Biology, can be used to demonstrate the conditions ...More

  • Researchers Discover How Bacteria Talk to Each Other and Our Cells
    Bacteria can talk to each other via molecules that they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Linköping University in Sweden are showing how bacteria control processes in human cells ...More
