Summary Introduction
Introduction:
Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane which surrounds the entire cell is composed of phospholipids and proteins. Peripheral proteins are generally found on the membrane surface and are temporarily attached to one face of the plasma membrane. Membrane proteins that traverse the entire cell membrane alone can serve as a membrane channel. A membrane channel aids in the transfer of solutes from one side of the cell membrane which is the selectively permeable to the other side of the membrane. Such integral proteins are called as transmembrane proteins. Hormones, like epinephrine (first messenger) do not have the ability to enter the cell through the cell membrane. Thus, it activates the production of a second messenger within the cell.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions.
1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction?
2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe:
a) What molecule do you recommend for the trial. Why?
b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?
3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale.
4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale.

- There is currently a H5N1 cattle outbreak in North America. According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host.
