It is estimated that for every human cell, there are nine microbial cells associated with an individual. That means that 90% of the total number of cells found in the human body is not human. The microorganisms that are associated with the human body, the microbiota, include both prokaryotes and eukaryotes.

Human skin, which as you know forms the outer covering of the human body, is colonized by more than a billion microorganisms. While most of these organisms are harmless, others can make you sick (especially if they can break the surface of your skin and enter into your body). Below is a list of some of the microorganisms that are known to make up the normal skin microbiome.

For this discussion, please do the following:

1. Choose one of the microorganisms from the list.

Note: You may not repeat a microorganism one of your classmates has already discussed until all microorganisms have been chosen at least once. (If you choose the same microorganism before they are all taken, your post will not be considered for grading.) Be sure to read through the posts before choosing and researching your own. If you must repeat a microorganism, your post must contain information that is not contained in the previous posting.

2. Conduct research on the microorganism you have chosen and using layman’s terms, please discuss in full how it contributes to the normal flora of the skin (why is it there? What is it’s function, etc). Your post must also explain:

• if the microorganism is prokaryotic or eukaryotic
• what part of the skin the microorganism can be found on
• if it helps, harms, or exists as commensal (have no effect)

3. Discuss what disease/medical condition might result if this microorganism breaks the surface of the skin.

4. Cite all references in APA format.

In order to receive full credit for this discussion, your initial response must address items 1-4. Please remember to provide any references. You must also respond to at least 2 initial responses of your classmates. All responses must contain at least 100 words.
