Compare and contrast the structure of the outer envelope (cell wall and other structures) of a certain Gram positive bacterium and a Gram negative bacterium. What happens to these cells when their cell walls are removed by the enzyme lysozyme?

1. When subjected to the Gram stain, mycobacteria either stain weakly red or don’t stain at all. Explain why, describing the differences between the cell envelopes of acid-fast, gram positive, and gram negative bacteria.

2. Synthesizing cell walls with mycolic acids requires a great deal of energy. Do you expect acid-fast bacteria to grow fast or slow compared to other bacteria? Explain.

3. What are the chemical differences between the Gram stain and the acid fast stain?

4. Describe how the LIVE/DEAD stain distinguishes between living and dead cells.

5. What results would you expect from spores? Explain your answer.

6. How can this stain be used to get an accurate measure of living vs. dead cells?

7. Develop a hypothesis that can be tested using the LIVE/DEAD stain

For this discussion question, in your own words, describe why the Gram stain is so important to all of microbiology, how it is performed, how it works, and compare the cell compositions it contrasts between Gram positive and Gram negative cells. Include why it is of such particular importance for medical microbiology. Also, giving two specific medically-significant microbe examples and descriptions for each group.
