Summary Introduction

To analyze:

The phase in which the urine of the children contains the lowest level of malathion metabolite in the following experiment.

Given:

Levels of metabolites (breakdown products) of malathion and chlorpyrifos in the urine of children taking part in a study of effects of an organic diet:

Malathion metabolite Chlorpyrifos metabolite
Study phase No. of samples Mean (µg/L) Maximum (µg/L) Mean (µg/L) Maximum (µg/L)
Nonorganic 87 2.9 96.5 7.2 31.1
Organic 116 0.3 7.4 1.7 17.1
Nonorganic 156 4.4 263.1 5.8 25.3

Introduction:

Organic foods are produced by using methods that meet the standard of organic farming. These foods are produced without any chemical fertilizers; only green manure or plant debris is added to the fields. The chemicals get accumulated in the body and cause diseases, but organic food is considered ecofriendly as it does not have chemicals.

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
