Detection of weaknesses of drug resistance

The World Health Organization (WHO) warns of an ineffective antibiotic status in many "viruses" worldwide. But recently, British scientists are happy to announce that they have discovered a weakness in the defense system of 'viruses' , which can improve the effectiveness of treatment of non-responsive infections. born.

Published in the journal Nature, the team at the University of East Anglia's School of Medicine in Norwich said it was determined that the factors affecting cell walls, which act as the "protective barrier" of most bacteria. drug resistance. Specifically, Professor Changjiang Dong and his colleagues have found a way and a way to transport the molecules that make up the membrane to prevent outside agents from invading gram-negative bacterial cells . Most importantly, the team has proven that the bacteria will die if this 'door' is disabled.

According to Professor Dong, the finding is important because drug-resistant bacteria are becoming a global problem causing hundreds of thousands of people to die each year. In particular, antibiotic resistant staphylococcus aureus (MRSA bacteria) are especially dangerous because they are resistant to many antibiotics.

Therefore, experts believe this finding could help to regulate many new drugs that directly attack the walls of bacterial cells rather than invade them to destroy them, thereby preventing the bacteria from growing. drug resistance.
