  • Chlamydia attacks with Frankenstein protein
    on November 7, 2018 at 6:02 pm

    When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, enters a human cell, it hijacks parts of the host to build protective layers around itself. Inside this makeshift fortress, the bug grows and reproduces, eventually bursting out in search of a new target and killing the host cell. While scientists have known for years that Chlamydia protects itself in this way, they were missing the mechanics until now. […]

  • Disrupting communication in infectious bacteria
    on November 7, 2018 at 6:02 pm

    Chemists report that they have inhibited the biosynthesis of a bacterial signal and, as a result, blocked the infectious properties of Pseudomonas aeruginosa, the most common germ found in health care facilities. […]

  • 'Bionic mushrooms' fuse nanotech, bacteria and fungi
    on November 7, 2018 at 1:24 pm

    Researchers have taken an ordinary white button mushroom from a grocery store and made it bionic, supercharging it with 3D-printed clusters of cyanobacteria that generate electricity and swirls of graphene nanoribbons that can collect the current. […]

  • Novel anti-inflammatory bacterial protein discovered
    on November 6, 2018 at 5:14 pm

  • Supermarket produce harbors antibiotic-resistance genes
    on November 6, 2018 at 12:32 pm

    Researchers have found that produce is a reservoir for transferable antibiotic resistance genes that often escape traditional molecular detection methods. These antibiotic resistance genes might escape cultivation-independent detection, but could still be transferred to human pathogens or commensals. The results highlight the importance of the rare microbiome of produce as a source of antibiotic resistance genes. […]
