Why is "superbug" MRSA so resistant? Genetic mutations help MRSA to be highly resistant to antibiotics.

!---- recently, a genetic mutation in methicillin-based staphylococcus (MRSA) makes bacteria highly resistant to antibiotics without reducing their pathogenicity, according to a recent study published in PLoS Pathogens.MRSA is resistant to almost all penicillin antibiotics, including methicillin and other penicillin serotonin, which is resistant to beta endamide enzymes.MRSA was first discovered in the UK in 1961 and is now widely spread, known as "superbugs". Antibiotics such aspenicillin and metaxiati do not bind well to the mecA gene-coded proteins in MRSA, meaning they cannot "kill" bacteria.the next phase of the study is to understand how this protein works with other factors in the bacteria to achieve higher levels of antibiotic resistance.the study will help researchers develop new drugs for MRSA. "Antibiotics have been the backbone of human health care for more than 70 years, but the emergence of drug-resistant superbugs is now a global disaster," said Simon Foster, lead researcher on thestudy.in order to fight drug-resistant microbes, we must understand them.our work reveals the complex mechanisms of bacterial resistance.".
