MRSA infection

Methicillin-resistant Staphylococcus aureus is an infection caused by Staphylococcus aureus bacteria. These bacteria are popularly known as staph. Unfortunately, Methicillin-resistant Staphylococcus aureus is a very common infection nowadays, and many doctors complain that every day they receive many patients with this infection. Staphylococcus aureus bacteria usually enter the nose and the skin of the healthy people and there resides. These bacteria are not very dangerous, because they do not cause some severe infections. Usually, Staphylococcus aureus bacteria cause certain skin infections, such as boils and pimples.

Doctor usually prescribes antibiotics to fight against these bacteria. However, over the years, these bacteria have become resistant to all antibiotics, which is called MRSA or methicillin-resistant Staphylococcus aureus. It is resistant to all beta-lactam antibiotics, such as methicillin, amoxicillin, penicillin, oxacillin, and many other antibiotics. However, the most effective against MRSA is proven to be vancomycin. In the majority of cases, staph bacteria just resided in the nose or the skin of a person and did not cause any infection. Nevertheless, MRSA infection usually affects very young and very old people, as well as those with weak immune system. This infection was first discovered in the United Kingdom in 1961. It is a contagious disease, which can spread from person to person by touch.

Causes of MRSA infection

Antibiotic resistance is the main cause for the occurrence of methicillin-resistant Staphylococcus aureus. Staphylococcus aureus bacteria are bacteria that live on the skin surface or the anterior nose, so when bacteria penetrate in the body of a person, the infection may appear. MRSA infection may be aroused by the indiscriminate use of antibiotics. Many people have the habit to take various antibiotics without any necessary reason. Many doctors usually prescribe certain antibiotics to treat viral infection, for example, a simple cold, neglecting the fact that antibiotics are not effective for the treatment of the viral infections. So they still recommend their massive use and because of that, the staph bacteria gradually become resistant to drugs that are often used.

Another cause for the incidence of MRSA infection is the mutation of staph bacteria. When Staph bacteria survive the first attack of any antibiotic, they become mutated and resistant to all others antibiotic. Every day many people eat certain food and drink water with trace antibiotics. Chicken, pork and beef are meats that contain antibiotic as well. MRSA infection may be also caused because of poor hygiene and unclean and dirty conditions where bacteria can multiply themselves a lot. The bad living conditions also promote the growth of bacteria.
