"From the Ted Talk by Bonnie Bassler: How bacteria "talk""

Unscramble the Blue Letters

To finish I'll just show you the strategy. In this one I'm just using the interspecies molecule, but the logic is exactly the same. What you know is that when that bacterium gets into the animal, in this case, a mouse, it doesn't initiate virulence right away. It gets in, it starts gnrowig, it starts secreting its quorum sensing mcoueells. It recognizes when it has enough biatreca that now they're going to launch their aattck, and the anmial dies. What we've been able to do is to give these virulent iinofcnets, but we give them in conjunction with our anti-quorum sensing molecules — so these are molecules that look kind of like the real thing, but they're a little bit different which I've depicted on this slide. What we now know is that if we treat the animal with a pathogenic bacterium — a multi-drug-resistant pathogenic bacterium — in the same time we give our anti-quorum sensing melucloe, in fact, the animal lives.

To finish I'll just show you the strategy. In this one I'm just using the interspecies molecule, but the logic is exactly the same. What you know is that when that bacterium gets into the animal, in this case, a mouse, it doesn't initiate virulence right away. It gets in, it starts growing, it starts secreting its quorum sensing molecules. It recognizes when it has enough bacteria that now they're going to launch their attack, and the animal dies. What we've been able to do is to give these virulent infections, but we give them in conjunction with our anti-quorum sensing molecules — so these are molecules that look kind of like the real thing, but they're a little bit different which I've depicted on this slide. What we now know is that if we treat the animal with a pathogenic bacterium — a multi-drug-resistant pathogenic bacterium — in the same time we give our anti-quorum sensing molecule, in fact, the animal lives.
