Infections caused by Staphylococcus aureus do not require treatment if they do not cause any clinical symptoms. This is because it can sometimes be normally present on the surface of the body, or in some cavities, as a conditionally pathogenic bacteria. Most of the time, however, it is found as a result of the corresponding infection and the corresponding pathogenic examination, which means that it has caused clinical symptoms, and then it needs to be treated with antibiotics. Staphylococcus aureus belongs to the gram-positive cocci, is a kind of septic cocci, so for the application of antibiotic treatment, generally is the choice of beta-lactam antibiotics, such as penicillin antibiotics or cephalosporin antibiotics. However, there are some Staphylococcus aureus, which are more resistant, have a special name called methicillin-resistant Staphylococcus aureus, and are resistant to most of the other beta-lactam antibiotics. The antibiotics that can be chosen at this point are vancomycin, linezolid or teicoplanin, but clinically the choice of antibiotics is usually based on the results of the drug sensitivity test after the Staphylococcus aureus has been cultured.
