GOOD: Single Dose of Antibiotic Found Effective in Quelling MRSA. “A single infusion of an antibiotic can clear serious bacterial skin infections — including methicillin-resistant Staphylococcus aureus, or MRSA — just as effectively as the 10-day regimen now used to treat patients, researchers reported Wednesday. Many patients do not finish the complicated treatment for these infections, which requires two infusions of antibiotics daily, often in a hospital. Such incomplete treatments may breed resistance to antibiotics in surviving bacteria. A single-dose therapy may make it easier to treat these dangerous infections, said the authors of the new study, published in The New England Journal of Medicine.”
