MRSA is the abbreviation for Methicillin-resistant Staphylococcus aureus. Methicillin is an antibiotic developed to combat bacteria that were resistant to Penicillin, which was the first of modern antibiotics and the "miracle drug". However, bacteria that are immune to Methicillin are becoming prominent. One type of bacteria that has mutated to become resistant to various antibiotics is Staphylococcus. Staph is a relatively common type of bacteria that exists almost everywhere. It evolved to become MRSA, many scientists believe, because of our tendencies to overuse antibiotics. Doctors prescribe unnecessary antibiotics, people do not take their antibiotics for the prescribed period of time, and many other things contribute to the current emergence of MRSA. MRSA invades your body and releases toxins and enzymes, which are very harmful. In more severe cases, the bacterium enters the bloodstream. Instead of being a localized infection, MRSA and the toxins it produces travel around your body. If the bacteria gains entrance to the bloodstream, the infection may prove fatal and incurable. Recently, MRSA infections have begun to become far more prevalent, a larger issue, and maybe even an epidemic. This is why it is crucial that we find a way to defend ourselves against the upcoming torrent of this potentially lethal bacterial infection.
