Viruses are considered non-living microbes, and yet they are responsible for many major disease outbreaks in humans, animals, and even plants. Consider the following: How are these non-living microbes able to reproduce without metabolic functions? Can viruses be exploited to help humans fight bacterial pathogens? Which viruses are able to stay dormant in the human body and reactivate later in life or when immune defenses are compromised? What impact might travel outside of the United States have in blood, tissue, or organ donation? Please answer question 1, 2, 3, and 4 if possible, thank you.

Which aspects of a microbial disease make it more likely to cause an outbreak? In other words, what advantages do these microbes have that others do not? Use an example of at least one outbreak in your description. 2. What measures are taken in the United States to prevent outbreaks from occurring? 3. What disease not prevalent in the United States do you think has the potential of causing a major outbreak in the United States? Name at least one reason to support your assertion.
Normal flora may cause opportunistic infections when:(a) They are continually nourished by the body.(b) The microorganism gains access to an unusual body site.(c) They are continually present.(d) They colonize any body surface.
New research suggests a link between some microbes that normally live in the body and seemingly unrelated major illnesses. The gum disease called periodontitis itself is not life-threatening, for instance, but it is a fairly good predictor for heart attacks. Bacteria that cause gum disease can trigger inflammation. Thinking back to your reading in Chapter 7, how do you suppose that this response also may be harmful to the heart?
