MRSA - A bacterium is spreading: Staphylococcus aureus is resistant to many antibiotics

Their golden yellow color is due to the graceful name Staphylococcus aureus: a bacterium that can cause wound infections and inflammation of the respiratory tract in humans. What makes it so dangerous is its resistance to certain antibiotics. Strict hygiene protects. In industrialized countries, globular bacteria are among the most important infectious agents of the 21st century. Staphylococcus aureus colonize at least temporarily about every third person: The skin and mucous membranes, such as the nasal vestibule, the pharynx, but also groin and the perianal are typical areas where you can find the bacteria.

Staphylococcus aureus triggers infection

They are part of the normal germ flora of the skin and do not harm a healthy person. In hospitals and nursing homes, however, they are feared, and here they also first appeared. Patients whose immune system is already weakened may experience prolonged purulent wound infections, respiratory tract inflammation, and blood poisoning. Often, the sufferers for months, wounds do not heal, no therapy seems to work.

Staphylococcus aureus also plays a role as a pathogen of food poisoning. If the pathogen proliferates in the food, so-called enterotoxins are formed which, when consumed, can lead to typical symptoms of intoxication such as vomiting and nausea.

Immune to antibiotics: MRSA

The abbreviation MRSA stands for methicillin-resistant Staphylococcus aureus - in plain language: they are immune to a variety of antibiotics such as penicillins and cephalosporins. It is estimated that about 40, 000 people are infected each year. According to information from MRSA-net, every fourth infection with Staphylococcus aureus is due to MRSA. Just a few years ago, only two percent of Staphylococcus aureus in Germany was multiresistant (MRSA), but now it is 25 percent, reports MRSA-net on its website.

So far, infection with MRSA occurred mainly in hospitals, where it is transmitted from person to person. In recent years, more and more cases of infections have been registered, which people have contracted outside of hospitals. At the same time, it became apparent that MRSA can also occur in animals, and increasingly in pigs. In the US, methicillin-resistant Staphylococcus aureus has been shown to cause breast inflammation in nursing women.

Therapy and treatment of MRSA

According to the results of a study in the journal Obstetrics and Gynecology (2008; 112: 533-537), this type of Staphylococcus aureus is particularly common if breast inflammation is accompanied by abscesses. It is interesting that most of the infections in the therapy were initially treated with antibiotics that are ineffective against MRSA. However, in most cases, healing was achieved by the treatment. Most patients were discharged without complications. A failure of therapy or even the death of a patient were in no case to complain.

Doctors therefore warn against the excessive use of antibiotics effective against MRSA during therapy. Especially important for the healing success is the regular emptying of the mammary gland by breastfeeding or pumping out and the possible therapy of an abscess.
