MRSA means methicillin-resistant Staphylococcus aureus. Bacteria of the type Staphylococcus aureus are found on the skin and mucous membranes of many healthy people. These bacteria can become resistant to the antibiotic methicillin and also most other antibiotics, i.e. insensitive.
Most often, MRSA settle only on man, without making him sick. The bacteria, for example, like to settle in the vestibule of the nose, throat, armpits and groin. Only when these bacteria enter the body through wounds or through mucous membranes can an infection break out. Since MRSA are insensitive (multi-resistant) to many antibiotics, the disease can take a severe course.
MRSA can be found where antibiotics are often used, especially in hospitals. In Germany, in previous years, about 20% of all Staphylococcus aureus bacteria examined in hospitals were multidrug-resistant. In recent years, there has been a decrease in the share of MRSA.
