An antibiotic refers to a medication that destroys or inhibits the growth of microorganisms (Tenover, 2006). Such microorganisms can be either bacteria or fungi, or certain parasites such as malarial parasites. Medical professionals are facing a serious problem about antibiotic resistance. Antibiotic resistance refers to the ability of microorganisms to withstand the effects of antibiotics (Tenover, 2006). Antibiotic resistance has become a common problem across the world because people are using antibiotics a lot and inappropriately. Proper use of antibiotics is the only way to control the spread of antibiotic resistance. This discussion will focus on methicillin-resistant Staphylococcus aureus bacteria, prognosis and treatment of its infections, and causes and prevention of its resistance.  

Methicillin-resistant Staphylococcus aureus is a bacterium that causes infections such as pneumonia, urinary tract infections, toxic shock syndrome, just to mention a few (French & Otter, 2010). Health physicians base the prognosis of methicillin-resistant Staphylococcus aureus infections on various symptoms such as fever, headache, lethargy, reddening of skin, and inflammation of wounds (French & Otter, 2010). Methicillin has been a common antibiotic in the treatment of Staphylococcus aureus infections over years. However, Staphylococcus aureus bacterium has become resistant to methicillin antibiotic. Causes of methicillin resistance include unnecessary prescription, incorrect diagnosis, and improper use of methicillin antibiotic, which results in a random mutation of the bacterium (French & Otter, 2010). A bacterium becomes a superbug when it carries a variety of resistance genes. Prudent prescribing of antibiotics is the best measure to prevent antibiotic resistance. Vancomycin antibiotic can effectively treat methicillin-resistant Staphylococcus aureus infections (French & Otter, 2010).

Therefore, antibiotic resistance is not futile because of a variety of preventive and control measures. Prudent prescribing of antibiotics can prevent the occurrence of resistance. This preventive measure can also avoid the emergence of superbug. Superbug results from the ability of a bacterium to carry a variety of resistance genes due to improper prescribing. If microorganisms have become antibiotic-resistant, use of new drugs will be necessary (French & Otter, 2010).
