MRSA refers to methicillin-resistant Staphylococcus aureus, which is a staphylococcus, a gram-positive bacterium that can be responsible for many septic diseases and is widely distributed in nature and can be detected in air, water, human and animal excreta. G. aureus can be treated with methicillin, or other beta-lactam antibiotics. However, because of the application of antibiotics, some bacteria have developed resistance, including methicillin-resistant Staphylococcus aureus, which is resistant to all beta-lactam antibiotics, and most of the macrolide and aminoglycoside antibiotics are also resistant. Therefore, it is difficult to treat clinically, and only antibiotics such as teicoplanin, vancomycin, linezolid, and norethindrone vancomycin can be chosen for treatment. And patients who have detected this bacterium should be isolated from contact to prevent this bacterium from causing transmission between different patients. The main thing to prevent the emergence of this bacterium is to abuse antibiotics less, which, if abused, can accelerate the emergence of this bacterium in nature.
