MRSA stands for Methicillin Resistant Staphylococcus Aureus. MRSA colonization means that a person is carrying bacteria that are antibiotic resistant that cause an infection called MRSA.A person with MRSA colonization may have the bacteria on his skin, inside his nasal cavities, on his or her groin area or even on the underarm areas.RSA stands for Methicillin Resistant Staphylococcus Aureus. MRSA colonization means that a person is carrying bacteria that are antibiotic resistant that cause an infection called MRSA.
Treatment and health care[edit] Bacteria are usually treated with antibiotics while viruses are treated with antiviral compounds. Eukaryotic pathogens are typically not susceptible to antibiotics and thus need specific drugs. Infection with many pathogens can be prevented by immunization.

If antibiotics are overused or used incorrectly there is a risk that the bacteria will become resistant-the antibiotic becomes less effective against that type of bacterium. A broad-spectrum antibiotic can be used to treat a wide range of infections. A narrow-spectrum antibiotic is only effective against a few types of bacteria. There are antibiotics that attack aerobic bacteria, while others work against anaerobic bacteria. Aerobic bacteria need oxygen, while anaerobic bacteria don't.
