  2. What are the most common vectors mentioned in the tutorial on transmission of disease?
  3. Which pathogens were mentioned in the Virulence Factors animations (host tissues and defenses)?  List all of the pathogens mentioned and then choose two to discuss.  In your discussion include:
  • How do they hide from host defenses?
  • How do they invade or penetrate the host?
  • Research how they reproduce, and ID them using at least three phenotypic descriptions (you can refer to the dichotomous key from the previous module for phenotypic descriptions).

TUI encourages all students to comply with APA style and format guidelines for proper citation of references.

Scholarly Content                  

Your case assignments are considered scholarly works. Your final work should include peer reviewed (scholarly) sources. Please use the formatting demonstrated in your Background section to cite the tutorials and readings from the Module Overview.

Please keep in mind that you should not use sources such as “Answers.com” or “Wikipedia” or “Wikianswers.”  None of these are scholarly sources and they can be “modified” by any registered user which makes them unreliable.

Appropriate Headings and Paper Flow

Remember that you are preparing a formal academic paper. Your paper should make use of appropriate headings and subheadings.  You should not cut and paste the questions posed and answer them like a “Question and Answer” session.  Your finished paper should read like an academic paper. Submit your final word document to the Case Assignment dropbox.
