Bacteria Experiment Assignment

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 of Staphylococcus epidermidis and Escherichia coli provided at the web links below, including the color and morphology of each organism.

a.  Identify each organism from part A3 as either gram-positive or gram-negative.
Note: These images are accessible through the Escherichia coli Gram Stain Image and Stapylococcus epidermidis Gram Stain Image web links below.
Note: The description from part A3 and the identification from part A3a belong in the results section of the lab report.
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.

Section I: Introduction

Logically explain, with sufficient detail, how the differences in cell wall structures of gram-positive and gram-negative bacteria cause them to stain differently with the Gram stain. Bacteria Experiment Assignment

 

Section II: Materials and Methods

Describe with sufficient detail the purpose of each of the four basic steps of Gram staining.  See Module 2: Gram Staining in the course material.
Section III: Results

  • Describe with sufficient detail the images provided at the “Bacterial Morphology and Staining Techniques” web link for Staphylococcus epidermidisand Escherichia coli, including the color and morphology of each  Links to the images are also found in the “Steps to Complete Task 1” section of Unit 1, Module 2 in the course material.

  • Accurately identify the shape and color of each organism from part A3.

 

  • Accurately identify eachorganism from part A3 as either Gram-positive or Gram-negative.

 

Section IV: Discussion

Provide a logical discussion of how the structure of gram-negative bacteria contributes to their ability to cause disease.

 

Note:  Review Module 1, Lesson 2:  Cell Wall for more information on Gram-negative cell walls.

 

Section V: Sources

The submission should include in-text citations for sources that are properly quoted, paraphrased, or summarized and a reference list that accurately identifies the author, date, title, and source location as available. Bacteria Experiment Assignment

 

Your submission must be your original work. No more than a combined total of 30% of the submission and no more than a 10% match to any one individual source can be directly quoted or closely paraphrased from sources, even if cited correctly. An originality report is provided when you submit your task that can be used as a guide.

 

Please review your UniCheck report and reword any similarities.  You can then generate a new UniCheck report to review before you resubmit.  Your UniCheck report should show less than 30% similarities overall, with less than 10% to any source.   You can find more information about the UniCheck report at https://cm.wgu.edu/t5/Frequently-Asked-Questions/What-is-Unicheck/ta-p/5619.
