The virulence factors in Gram negative bacteria which allow them to cause diseases. Introduction : Gram negative bacteria are the pathogens causing majority of diseases in humans. They can sustain life at 37℃ and can escape the immunity defenses of the host body. They have an outer membrane containing lipooligosaccharides, composed of Lipid A and polysaccharides, which helps them to infect host cell and also provide antigenic properties. These bacteria have certain virulence factors such as capsules, fimbriae, exotoxins, iron binding compounds, haemolysin and a type III secretion system.

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
