The immune system of the vertebrates gives protection against the infectious foreign substances or pathogenic organisms. It is a complex biological reaction which involves in the specific and nonspecific defense against the infectious agents. The pathogenic damages to the defense cells indicate the sign of inflammation. After inflammation, the phagocytic cells are initiated to destroy the invading microbes. The phagocytosis is a series of process in which the contact of the microbes on surface of the phagocytic cell involves in the chemotactic adherence, ingestion and digestion process.

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. Mutation 1 Mutation 2
