  • Biologists Discover That Bacteria Communicate Like Neurons in the Brain
    Biologists at UC San Diego have discovered that bacteria--often viewed as lowly, solitary creatures--are actually quite sophisticated in their social interactions and communicate with one another through similar electrical signaling mechanisms as neurons in the human brain. ...More

  • E. coli More Virulent When Accompanied by Beneficial Bacteria
    Scientists wonder why some people get so sick and even die after being infected by the foodborne pathogen E.coli O157:H7, while others experience much milder symptoms and recover relatively quickly. Now Penn State's College of Agricultural Sciences researchers believe they ...More

  • UCSB Researchers Demonstrate How Gram-Negative Bacteria Deliver Toxins to Kill Neighboring Bacteria
    It's bacteria against bacteria, and one of them is going down. Two UC Santa Barbara graduate students have demonstrated how certain microbes exploit proteins in nearby bacteria to deliver toxins and kill them. The mechanisms behind this bacterial warfare, the researchers ...More

  • Biologist Investigates How Gene-Swapping Bacteria Evade Antibiotics
    A scientific peek into bacteria boudoirs is revealing how "sex" among disease-causing microbes can lead different species or strains to become resistant to antibiotic medications. Dr. Kelli Palmer, assistant professor of biological sciences at the University of Texas at ...More

  • Bacteria Use Toxins to Turn Our Own Bodies Against Us
    Researchers who have revealed a highly efficient way that bacteria use toxins to interrupt the immune response say that until now, the trickery of these toxins has been underappreciated in science. Bacteria harm the body by releasing toxins -- proteins that are ...More

  • Tracing the Evolution of a Drug-Resistant Pathogen
    To fight a pathogen that’s highly resistant to antibiotics, first understand how it gets that way. Klebsiella pneumoniae strains that carry a particular enzyme are known for “their ability to survive any antibiotics you throw at them,” says Corey Hudson of ...More
