Controlling microorganisms in the environment is becoming increasingly difficult due to the development of resistance to common disinfectants and antiseptics. Some examples of chemicals that have been or which are currently being used are triclosan, triclocarban, benzalkonium chloride, and chloroxylenol, to name a few. Many scientists are now turning their attention to other methods to control bacterial contamination. Discuss using 'phages' and other methods to control bacteria. Do you think these methods are better? Safer?

In the 'Bacterial Growth' ( http://www.hhmi.org/biointeractive/bacterial-growth ) video Dr. Brett Finlay shows how bacteria can grow rapidly to incredible numbers. He also explains what limits this explosive growth. 1) Based on what he said, describe why the over use of antibiotics to treat one bacterial infection sometimes leads to 'super infections' of a different bacterial species like in the case of Clostridium difficile ( https://www.cdc.gov/HAI/organisms/cdiff/Cdiff_infect.html (click link for more info on C. diff).
