How can we keep our immune systems in fighting shape? What happens when our immune systems are responding well or are missing key genes? is there targeted gene therapies that can be used to help save lives of those most at risk from infection?  How does our body hunt down and stop Listeria in it's tracks? Plus undercooked wild game or pork can lead to parasitic infections, but how does the body fight back?
