Bacterial antibiotic resistance is a topic that is causing increasing concern in the health community. Antibiotics are a necessary drug to help protect and heal us from pathogenic infections that our immune system is unable to successfully combat on its own. However, bacteria are very adept at utilizing evolutionary processes to develop antibiotic resistance in order to promote their own survival, reproduction and persistence. The development of antibiotic resistant bacteria is occurring at an alarming rate. Researchers are investigating the mechanisms that confer resistance on bacteria. With techniques for genomic sequencing now readily available, understanding of genetic mechanisms of resistance and evolution as a whole has been advancing rapidly. Researchers have found that bacteria are very adept at gene mutation and horizontal gene transfer. New insights regarding pleiotrophy and epistasis have been provided through these techniques. A possible result of this research will be the discovery of new antibiotic therapies. However, as the research is demonstrating, even if we develop new antibiotics, bacteria will develop resistance to them. Thus, important considerations to be taken from the research include finding ways to slow the development of resistance as we will most likely never be able to stop it entirely.
