An MRSA cell releases decoys, allowing it to evade an antibiotic
The superbug MRSA uses decoys to evade a last-resort antibiotic, reveals new research. The findings, from scientists at Imperial College London , suggest potential new ways of tackling the bacteria, such as interfering with the decoys. Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for thousands of deaths around the world each year. However, because the bacteria are resistant to many different antibiotics, treatment options are limited, and often ineffective. One of the few antibiotics that can be used against MRSA is a drug of last resort known as daptomycin. However nearly a third of MRSA infections are not cured by this drug, leaving patients with a poor prognosis. These fat molecules act in a similar way to the decoy flares released by fighter planes to avoid a missile.
