Staphylococcus aureas versus Methicillin Resistant Staphylococcus aurea

From staphylococcus aureus to MRSAAbstractI investigated the difference between staphylococcus aureas and its super bacteriaform of Methicillin-resistant staph aureas. I used books, websites, andscholarly projects to understand the topic at a molecular level. After researchingpenicillin, Staphylococcus aureas, and Methicillin-resistant Staphylococcus aureas, Ifound that both the dose and the bacteria use enzymes as their defense and attackmechanism. Penicillin uses a -lactam ring as a substrate to clog the active site oftranspeptidase, and in defense, the bacteria uses -lactamase to break down the -lactamring. I hope to continue research on super bacteria to determine whether or not othersuper bacteria such as Enterococcus faecium and Streptococcus pyogenes use the samedefenses. I found growing number of super bacteria both interesting and disconcerting.My conclusion is that antibiotics and up to now antibacterials must be monitored more closelyif we wish to keep the upper hand over bacteria.In 1928 when Alexander Fleming saw the bacteria-free ring of inhibition make byStaphylococcus aureus around Penicillium notatum (penicillin) in his petri dish, he musthave been shocked and thrilled. By 1940, penicillin was being produced for a very eagerpublic. 4 It was our miracle dose bacterial infections were a thing of the past. However,the use of penicillin was quickly abused, and problems arose. A target bacteria,Staphylococcus aureas soon learned to beat the scientist who thought he had themconquered. MRSA, or Methicillin-resistant Staphylococcus aureas is very similar toStaphylococcus aureas, but it is no longer affected by penicillin or methicillin, the mostcommon antibiotics... ...iel C., and Natalie C.
