The Super bug

Many of you may have heard of the “super bug.”  The reason for its name is because many people take too many different forms of antibiotics for just about anything.  When people take too many antibiotics, it causes bacteria to become resistant to antibiotic agents.  As the bacteria become drug resistant, we are becoming more at risk for infections that we cannot cure.  Please read the article titled, “Resistance to Antibiotics: Are We in the Post-Antibiotic Era?”  Please provide your thoughts on drug resistance, and explain what you thought was an important fact from this article.
