a.

Summary Introduction

To define: Cooling mechanisms that are activated when hypothalamus senses increased body temperature above-set point.

Introduction: The level at which the body attempts to maintain its temperature is known as temperature set point. When the set point increases, it results in fever. When the set-point is not increased but the temperature is increased, the outcome is hyperthermia.

b.

Summary Introduction

To define: Mechanisms that are activated when the hypothalamus senses the temperature below the set point.

Introduction: The hypothalamus works together with other organs of the body in controlling temperature. Temperature is essential for the body to carry out all the metabolic process. Water evaporates from the skin to maintain body temperature in a healthy range.

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
