The Sphinx is describing are the life stage of man. Obviously, bacteria don't have legs (flagellin is a good substitute though!) but we need to consider the life stages of our microscopic majors just as well.  It is in these stages that they can benefit us or be the most harmful.  That is why you will be writing an essay about the life stages of the bacterium and how that knowledge of each stage can provide needed insight/information that scientists and health professionals can utilize.  You can start your essay by including a picture of a growth curve (which can be interpreted as a life cycle). What you want to include in your essay is the following:

1. description of what is happening at each stage

2. What is happening to the microbial population (increasing/ decreasing/ staying the same?  

3. levels of nutrients for the microorganisms?

4. virulence/pathogencity levels? is the cell pathogenic at each stage? is there a stage where it is more pathogenic than another?

5. Which stage is the cell most vulnerable and which is it most resistant to attach and the reasons why you state that.

In this assignment you will be characterizing in your own words the bacterial cell growth curve as related to nutritional availability and survival.

Please include answers to the following:

• What are the phases of the bacterial growth curve and what are the biological processes occurring in the microbial cell?
• What are the macro molecules/nutrients necessary for bacterial growth and address what their levels may during each phase?
• How might a microbial cell compensate for lack of nutrients?
