MRSA is Methicilin-Resistant Staphylococcus aureus, this is a bacteria that in many cases does not cause problems, nonetheless, if proliferates can cause grave affections on the skin, respiratory system, and blood. In the specific case of MRSA, we are talking of a bacterial strain of Staphyloccocus that has multiple resistance to antibiotics, this makes it more difficult to treat. This type of multiple resistance is generated by the abuse of antibiotics, that is to say, antibiotics are used even when the disease is viral and not bacterial or the treatments are not fully accomplished. So what is the best way to reduce multiple resistance? use antibiotics only by medical prescription and always complete the treatment.
