MRSA Notes

Some researchers have developed a molecule that can distinguish between good and bad cells and destroys the bad ones by slashing them and allowing their cell material to leak out. From Newswise | Researchers Design Antimicrobial, Technique to Watch It:

To test its ability to distinguish friend from foe, the researchers pitted the new compound against microbes such as E. coli and Staphylococcus aureus—the bacterium whose resistant strains plague hospitals—and against human red blood cells. The tests revealed that the new design is indeed both lethal and selective. While it slashed bacterial membranes with zeal, the compound left the human blood cells alone.
