Sometimes a pathogen develops resistance against a particular antimicrobial agent and sometimes pathogens develop resistance against a wide variety of antimicrobials. Some examples of multiple-drug-resistant strains of microbes are: Staphylococcus, Streptococcus, Enterococcus, Plasmodium and many others are resistant to more than two different type of antimicrobial agent. These multi-drug-resistant microbes are called as superbugs due to their ability to resist a wide range of antimicrobials.

Expert Solution & Answer

Answer to Problem 1Q

Correct answer:

Enterobacteriaceae is on the CDC’s (center for disease control) “Urgent Threat” list because of its potential resistance to antibiotics. Therefore, option (d) is correct.

Option (d) is given as “Enterobacteriaceae”.

Explanation of Solution

Justify the reason for the correct statement:

One of the bacterial families which top the “urgent list” of infections on CDC is Enterobacteriaceae. Enterobacteriaceae is a carbapenem drug-resistant bacteria family. This bacterial family has developed resistant to almost all existing antibiotics making it most harmful pathogens.

Hence, option (d) is correct.

Justify the reasons for the incorrect statements:

Option (a) is given as “Staphylococcus saprophyticus”.

Staphylococcus saprophyticus the main causative agent of urinary tract infections, is not on the “urgent list” of CDC. Hence, it is a wrong answer.

Option (b) is given as “Trichomonas vaginalis”.

Trichomonas vaginalis causes the asymptomatic vaginitis infection in females. Trichomoniasis is a flagellated protozoan. It is not on the “urgent list” of CDC. Hence, it is a wrong answer.

Option (c) is given as “Herpesvirus”.

Herpesvirus is known to be resistant against some antiviral drugs but is not on the “urgent list” of CDC. Hence, it is a wrong answer.

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

Conclusion

Enterobacteriaceae is on the “urgent list” of CDC as this bacterial family is known to have developed resistance against most of the antibiotic drugs.

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
