High HDL cholesterol has been associated with a reduced risk for heart attack, but how it actually reduced the risk remained unclear. It turns out that some mechanisms that raise HDL do not seem to lower the risk of heart attack.
MRSA (methicillin resistant staphylococcus aureus) is a type of staphylococcus bacteria (staph) that is resistant to beta-lactam antibiotics. MRSA is contagious and can cause life-threatening infection. MRSA isnât found in the natural environment (soil or water).
Though most staph infections can still be successfully treated, it may only be a. matter of time before the bacteria become resistant to all currently available medications. Staph infections can range from minor skin problems to food poisoning, fatal pneumonia and surgical wound.
