Researchers may have made some headway in the fight against antimicrobial resistance. A paper published online in Nature today (abstract only unless you’re a subscriber) discusses a new method to grow bacteria that have previously been uncultivable. In doing so, researchers have discovered a new antibiotic they’re calling teixobactin that is active against gram-positive organisms (specifically, a precursor of peptidoglycan present in the cell wall). Initial tests suggest bacteria can’t form a resistance to this mode of action.
Maybe there’s something to the expression “throw some dirt on it and get back in the game” after all.
