Microbiology

A. Write a lab report about the “Bacterial Morphology and Staining Techniques” lab kit experiment in which you
do the following:
1. Explain how the differences in cell wall structures of gram-positive and gram-negative bacteria cause them
to stain differently with the Gram stain.
Note: The explanation from part A1 belongs in the introduction section of the lab report.
2. Describe the purpose of each of the four basic steps of Gram staining.
Note: The description from part A2 belongs in the materials and methods section of the lab report.
3. Describe the images provided at the “Bacterial Morphology and Staining Techniques” web link for
Staphylococcus epidermidis and Escherichia coli, including the color and morphology of each organism.
a. Identify each organism from part A3 as either gram-positive or gram-negative.
4. Discuss how the structure of gram-negative bacteria contributes to their ability to cause disease.
Note: The discussion from part A4 belongs in the discussion section of the lab report.
B. Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or
summarized.
C. Demonstrate professional communication in the content and presentation of your submission
