- Question 34 Which of the following is NOT an example of innate antimicrobial drug resistance? slow growth (high doubling time) O having a tough, impermeable cell wall composition O having an outer membrane O recieving a gene for B-lactamase Question 35 Which of the folowing is a rationale behind semisynthetic antimicrobials? O Overcome bacterial resistance mechanisms O Increase dysbiosis O Decrease a drug's therapeutic index O Prevent uptake by bacterlal cellsQUESTION 5You are asked to recommend an antibiotic to treat potential pathogenicityt in an animal. Describe a method which will allow you to make this recommendation.Please help me answer questions Part IV- 1, 3, 4 Thank you, Heres a link to the PDF https://www.cusd80.com/cms/lib/AZ01001175/Centricity/Domain/8922/eofad.pdf
- Question 17 MRSA are resistant to because they have a nucleases; mutant chromosome O gyrase inhibitors; mutant helicase tetracycline; mutant ribosomes O beta-lactam antibiotics including methicillin; mutant bacterial transpeptidase Question 18Question 14 What is the vaccine delivery system used in the Moderna's COVID-19 vaccine? O Fentanyl patches O target-controlled infusion (TCI) devices O Lipid Nanoparticles O Transdermal drug deliveryQUESTION 2 Latent herpesviruses exist inside cells as nothing more than a loop of herpesvirus DNA. The viruses do not express their genetic material. How does this help them avoid the action of your T cells? O Because no viral proteins are being made, there are no viral proteins displayed on the surface of an infected cell. Tc can't find the infected cells Most likely herpesviruses can only infect Tc in the first place, and they cause your Tc to die. O There are no viral proteins for antibodies (synthesized by Tc) to bind to. QUESTION 3 Cold sores around the mouth are caused by a herpesvirus, HSV-1. Given that HSV1 seldom produces lesions in any place other than near the mouth, it makes sense that HSV-1s is latent in O white blood cells. O liver cells. O nerves that innervate skin near the mouth.
