The factors besides antibiotic consumption that influence the numbers and types of microflora in the human body. Introduction: Microflora or microbiota is the collection of microbes that dwell in the human body in parts such as skin, mammary glands, placenta, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary, and gastrointestinal tracts. It has been estimated that the surface area of the skin supports about 10 12 bacteria. Microorganisms in the human body play an important role in maintaining human health. For example, bacteria present on the skin can protect the skin from infection of other organisms or gut bacteria that salvage unabsorbed dietary sugars and protecting the host from pathogenic organisms.

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
