Week 5 Discussion

 

Some potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards. What can hospital personnel do to reduce the spread of these pathogens?

Week 8 Discussion

 

Fifteen-year-old Dolores was embarrassed to talk with her mother about the pain she felt in her “private parts,” but she was worried she might have gotten a disease, despite Nick’s assurance that she was his “first.” Her mother insisted that Dolores see a doctor, who discovered cervical lesions caused by a virus associated with cancer.

 

What sexually transmitted virus is involved?

 

How should the physician treat the lesions?

Week 8 Assignment

 

Microbial Journal Article Review

 

In this assignment, students will review a microbial journal article.

 

Choose one article from a primary scientific literature source that uses a microbe as a model organism/system and write a comprehensive summary of the study that answers the following questions:

 

Choose one article from a primary scientific literature source that uses a microbe as a model organism/system.

 

NOTE: Many free articles may be obtained from http://www.pubmed.gov or visit the WCU library.

 

Write a summary of the study that includes:

 

Why did the scientists perform the study (i.e., description of background)?

 

What was the hypothesis (or hypotheses) under investigation?

 

What were the major results and did they support or negate the hypothesis? Which key techniques were used to achieve these results?

 

Why are the results significant and do they point to further/future studies? In other words, why does this article matter and what should or could be done next?

 

Why did you choose this particular article to review? Was it interesting, informative, clearly written, or none of the above?

 

Compose your review in current APA Style and include:

 

A title page

 

Answers to the questions above in paragraph format (2 or more pages)

 

A reference page with the reference for your article and any other sources used in your review.

Week 9 Assignment

 

Lab Signature Assignment: Microbial Disease Report

 

Your Lab Signature Assignment is an oral report on a microbial disease. Create a three- to five-minute video response that includes the following:

 

Select a disease that affects humans or animals whose causative agent is a bacterium, virus, fungus, protozoa, or other microorganism.

 

Create and deliver a presentation on your chosen disease in which you report on each of the following in detail:

 

Causative Agent: Describe and classify the microbe involved. If known, explain how the microbe causes/transmits the disease or interferes with normal body function. Also, describe the vector and/or life cycle for the microbe (if applicable).

 

Population(s) affected: What population(s) is/are at highest risk of contracting the disease? Are there any groups of people who should be tested? Please include statistical/geographical data and trends (from the Centers for Disease Control and Prevention, World Health Organization, or other source [http://www.cdc.gov, http://www.who.int, etc.]).

 

Course of Disease: What are the usual signs/symptoms of someone with the disease? How is the disease diagnosed? What is the usual time course for recovery? Are there complications and/or long-term effects?

 

Interventions: Describe possible treatments and/or medical interventions. Is there a vaccine available? How can the disease be best prevented or kept under control?

 

Videos can be recorded using any software or tool, but all videos are required to be uploaded to My Panopto Videos for assignment submission.

 

You can also use the Panopto Desktop Recording tool to create your video.
