The growth phase in which an organism is most sensitive to an antimicrobial agent. Introduction: Bacterial growth occurs and there are four distinct phases of the growth curve : lag, log, stationary and death phase. The initial phase is the lag phase followed by the log phase which is a phase of exponential growth, then a stationary phase where growth reaches a plateau and finally the death that is the last declining phase.

Answer 1

Question

Definition Definition Phase during which the number of bacteria cell deaths gradually equals the number of viable or actively dividing cells due to decreased reproduction rate. Microbes utilize all nutrients present in the growth medium to multiply during the growth of the bacterial population, which results in the deposition of waste matter, toxins, and inhibitory compounds in the media. This changes media conditions, such as temperature and pH, creating an unfavorable environment for bacterial growth. Here, the growth rate becomes stabilized.

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
