Unfortunately, Methicillin-resistant Staphylococcus aureus is a very common infection nowadays, and many doctors complain that everyday they receive many patients with this infection. Staphylococcus aureus bacteria usually enter thenose and the skin of the healthy people and there resides. These bacteria arenot very dangerous, because they do not cause some severe infections. Usually, Staphylococcusaureus bacteria cause certain skin infections, such as boils and pimples.

Doctor usually prescribes antibiotics to fightagainst these bacteria. However, over the years, these bacteria have becomeresistant to all antibiotics, which is called MRSA or methicillin-resistantStaphylococcus aureus. It is resistant to all beta-lactam antibiotics, such asmethicillin, 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 residedin 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, aswell as those with weak immune system. This infection was first discovered in the United Kingdomin 1961. It is a contagious disease, which can spread from person to person bytouch.

Causes of MRSA infection

Antibiotic resistance is the main cause for the occurrenceof methicillin-resistant Staphylococcus aureus. Staphylococcus aureus bacteriaare bacteria that live on the skin surface or the anterior nose, so when bacteriapenetrate in the body of a person, the infection may appear. MRSA infection may be aroused by the indiscriminateuse of antibiotics. Many people have the habit to take various antibioticswithout any necessary reason. Many doctors usually prescribe certainantibiotics to treat viral infection, for example, a simple cold, neglectingthe fact that antibiotics are not effective for the treatment of the viralinfections. So they still recommend their massive use and because of that, the staph bacteriagradually become resistant to drugs that are often used.

Another cause for the incidence of MRSA infection isthe mutation of staph bacteria. When Staph bacteria survive the first attackof any antibiotic, they become mutated and resistant to all others antibiotic. Every day many people eat certain food and drinkwater with trace antibiotics. Chicken, pork and beef are meats thatcontain antibiotic as well. MRSA infection may be also caused because of poorhygiene and unclean and dirty conditions where bacteria can multiply themselvesa lot. The bad living conditions also promote the growth of bacteria.
