Summary Introduction

Introduction:

Antibiotics are sometimes naturally formed chemicals which are released by soil fungi and bacteria in their environments. It provides them the ability to compete against microbial communities. The saturation of antibiotics into the surrounding deeply affected the evolution of bacteria.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

A compound synthesized by bacteria or fungi that destroys or inhibits the growth of other microbes is an antibiotic. Therefore, option (b) is correct.

Option (b) is given as “antibiotic”.

Explanation of Solution

Justify reasons for the correct statement:

Antibiotics can be produced only by a living organism such as bacteria. Antibiotics can be generated either alone or by different groups of microorganisms such as bacteria, actinomycetes,and fungi. More than thirty antibiotics have been isolated from those groups. Microbes that can produce antibiotics are useful for the prevention and treatment of many diseases including bacterial and fungal disease. For example, penicillin and tetracycline.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “synthetic drug”.

Drugs that are synthesized in the laboratory by mimic the action of natural compounds by chemical reactions are called synthetic drugs. Hence, it is a wrong answer.

Option (c) is given as “interferon”.

Interferon, a human-based compound that is a glycoprotein. It is produced by leukocytes and fibroblasts in response to many immune responses. Hence, it is a wrong answer.

Option (d) is given as “competitive inhibitor”.

A form of enzyme inhibition that contains the binding of an inhibitor that preventsthe binding of the target molecule of the enzyme is termed as a competitive inhibitor. Hence, it is a wrong answer.

Hence, options (a),(c), and(d) are incorrect.

Conclusion

Antibiotics eradicate the bacteria that are susceptible to departing from the resistant

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
