Summary Introduction

To summarize:

The current knowledge of normal biota in the human mouth.

Introduction:

Infections or diseases refer to an abnormal condition of body that disrupts important physical and physiological functions of the body. A disease is caused by improper diet, lack of exercise, various infectious agents that are present in nature, toxic substances, genetic disorders, stress, and depression.

Summary Introduction

To explain:

The reason that many patients undergoing dental surgery are placed on antibiotic treatment before procedure.

Introduction:

Dental caries, which is also called tooth decay, serve as most common infectious disease of human being. It involves dissolution of solid tooth surface called enamel because of the metabolic actions of the bacteria. It is caused by two types of bacteria Streptococcus mutans and Streptococcus sorbins. While some other species of Streptococcus and lactobacilli also causes dental carries. Early childhood caries are caused by Scardovia wiggsiae.

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
