The Emergence Of Staphylococcus Aureus Mutations

1322 words - 6 pages

Human civilizations have existed for thousands of years but with the existence of these civilizations diseases were right there with them. Even before great civilizations emerged, such as the Greeks and Romans, diseases have been around preying on animals and villages. When a civilization emerges it means that people have come together and built a society. These societies allow for diseases to spread easily because of unsanitary conditions and people being in close contact with each other on a normal basis. But in the past few decades science has allowed us to find cures or treatments for most diseases out there, yet there are still diseases that everyone knows about going around causing the deaths of thousands of people every year. This is because most of these diseases have emerged from past diseases that have been cured or we don’t have the technology to treat them yet. New diseases emerge every year from old diseases such as the flu which is why we’re constantly making a new flu vaccine yearly. The way these diseases emerge is usually where a small portion of the microbe causing it is immune to whatever treatment is used to destroy it. These microbes will then multiply themselves and eventually cause a new strain of disease that needs a new treatment method.
For example, Methicillin-resistant Staphylococcus aureus (MRSA) is a strain of bacteria that mutated from the bacteria Staphylococcus aureus. This specific strain came about by natural selection against Methicillin, as its name suggests. The strain must have already previously existed before patients were treated with Methicillin and when they were the Methicillin killed off all of the bacteria besides the MRSA ones allowing them to spread about while the host felt like they were in good health.
Most people are unaware of the possible symptoms of having a Staphylococcus infection. They just hear about the spread of the disease on the news and are worried they might get it so they then take special care of themselves and their family to prevent it. This is probably for the best though considering if people knew how bad the symptoms of a staph infection were they would be a lot more worried.
The most common symptom of having a staph infection are skin infections such as red swollen areas on the skin with boil like spots that usually are either full of pus or drain often. But some of the worst symptoms of staph can occur when it enters the bloodstream. When the bacteria spread to the bloodstream it is known as bacteremia or sepsis and this can cause heart failure and if the infection goes into the bones it can cause osteomyelitis which is severe inflammation of bones. Staphylococcal sepsis in people has a mortality rate of over 80% (Stoppler).
Prevention of Staphylococcus aureus isn’t as easy as most people believe either. You’ll hear people saying to wash your hands frequently to keep the bacteria off, but this only somewhat helps prevention. People actually always have staphylococcus...
