Penicillin was a major leap in humanity’s fight against hostile bacteria and infections. However, in the past few decades we have come across some strains of bacteria that are resistant to all antibiotics doctors use posing a serious threat to patients since we have nothing to combat hostile bacteria. Researchers from Case Western Reserve University may have found a new approach to tackle this problem that does not involve using antibiotics. Researchers have successfully cured sepsis in mice using molecules called F12 and F19 to block the bacteria. These molecules bind to one of the bacteria’s protein vital for toxin production, rendering it useless. This makes the bacteria effectively harmless. In the tests conducted on untreated mice with sepsis, researchers found that all mice treated with F12 and F19 molecules survived.
Additionally, they found that adding these molecules to even low-strength antibiotics made them highly efficient at fighting off infections. The biggest advantage of using these molecules is that they don’t kill the hostile bacteria, they just ‘neutralize’ them in a way hence the bacteria have no evolutionary incentive to develop resistances.
