In the meanwhile, there are ways of preventing new MRSAs from developing. Bacteria have been around for a very long time; they are some of the oldest organisms on the planet. Consequently, they have obtained quite a few nifty tricks for responding to outside stimuli and competition. For instance, when a bacterium dies, it leaves behind its innards – the information booklet for system control (DNA) being the most important subset of this carrion. Other bacteria that come into contact with these remains can subsequently absorb and incorporate the free-floating DNA into their own genome. This allows them to obtain new information about how to survive in their environment.
One of these ways of adapting to their environment involves antibiotic resistance. If the bacterium that died survived exposure to an antibiotic previously, chances are that it possesses the ability to fight that drug. This information is contained within its genetics, and these genetics can propagate across species through a mechanism known as transformation. Seeing an opportunity to survive, the bacteria will absorb the DNA and become antibiotic-resistant.
Therefore, there is one extremely important way that everyone can contribute to the fight against organisms like MRSA: Finish the antibiotics that have been prescribed to you. When doctors prescribe antibiotics, they deliberately provide a specific amount. This is to ensure that all bacteria involved in the infection are eradicated and do not escape to spread their antibiotic resistance to others. So, in finishing that pesky, white, hardly palatable disc the doctor gave you, even after your symptoms have disappeared, you are contributing to the future survivability of mankind.
Thank you for your service.

More About Dr. Velupillaimani:
Ramesh Velupillaimani, PhD, is a professor of biosciences in the College of Science, Engineering and Technology at Grand Canyon University. He received his PhD in microbiology and was awarded with the prestigious Lady Davis Fellowship to work as a post-doctoral research associate at the Silberman Institute of Life Sciences, Hebrew University of Jerusalem, Israel. Before he joined Grand Canyon University, Dr. Velupillaimani held a research assistant professor position at the Center for Bioenergy and Photosynthesis at Arizona State University. His research interests focused on the molecular mechanism of photosynthetic energy transduction. He has developed many biological techniques including a simple detection medium for dermatophytic fungi, a novel technique to purify photosynthetic membrane proteins from cyanobacteria and green algae and a simple technique for chloroplast transformation in eukaryotic green alga chlamydomonas reinhardtii. Dr. Velupillaimani holds membership in the following professional societies: American Chemical Society and American Society for Advancement of Sciences. He has contributed three chapters in the Methods in Molecular Biology series and Humana Press USA, along with a chapter in advances in photosynthesis and perspiration. He is the author of several research papers published in top national and international journals and books. In addition to teaching, Dr. Velupillaimani oversees the research program in the Center for Antimicrobial Products at GCU.
More About Nicolas:
Nicolas Sever is a third-year undergraduate student studying biochemistry and molecular biology at Grand Canyon University. He intends to pursue doctoral studies in the same field with an emphasis in immunology research. Rationality and the scientific method have always intrigued him, likely because curiosity and the thrill of exploration are powerful driving forces behind his personality. During summer 2017, Nicolas worked at a veterinary hospital and decided that applied science in the medical fields was not something he desired to pursue – he is of the questioning sort and prefers to think outside of the box. So, with that in mind, he made the decision to obtain a career in the field of biology, particularly on the more microscopic end of that domain. An avid learner, questioner and inspired writer, Nicolas also enjoys physics, philosophy, the humanities and religious topics.
