  • Discovery of Controlled Swarm in Bacteria
    A study led by researchers from Universitat Autònoma de Barcelona (UAB) describes one of the mechanisms in which pathogenic bacteria populations control the way they spread over the surface of the organs they infect and stop when they detect the presence of an ...More

  • Gut-Residing Bacteria Trigger Arthritis in Genetically Susceptible Individuals
    A single species of bacteria that lives in the gut is able to trigger a cascade of immune responses that can ultimately result in the development of arthritis. Our gut, like that of most mammals, is filled with thousands of species of bacteria, many of which are helpful and ...More

  • How Bacteria Make “Syringes” to Infect a Host
    For a successful infection, bacteria must outwit the immune system of the host. To this aim, they deliver so-called virulence factors through a transport channel located in the bacterial membrane. In some bacteria this transport channel is formed like a syringe, enabling ...More

  • The Right Response to Every Pathogen
    In the event of an infection, the immune system releases messenger substances. These molecules can either activate immune cells to defeat invading pathogens, or inhibit them to prevent an excessive immune reaction. For this, the immune system has to decide very quickly what ...More
