Comment on Researchers Train Bacteria to Consume Tumors from the Inside Out

  Theoretically it shouldn’t. The bacteria should die once it reaches living cells which contain oxygen. The question is how does it kill the external living tumor cells

    There’s another study from the same team about successfully modifying the species to resist oxygen “at key moments” lol

    This article has more specific details about the research. Not to be too reductive but quorum sensing is the mechanism that typically flips an infection from passive growth into “start killing this bitch we have the numbers now”

    So what they think they’ve done is create a mechanism to lets them turn the oxygen resistance on and off, but what’s going to happen is the cells that then mutate out of turning if off are going to be the simply superior organism.
