- Why doesn’t penicillin act against any eukaryotic pathogens?Which of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. RhinovirusWhy are Archaea resistant to penicillin?
- An antimicrobial drug binds to the HIV reverse transcriptase enzyme, preventing it from working. Which of the following is true of this drug? It would inhibit early replication steps of some viruses, but not affect normal eukaryotic cell activity. It would directly interfere with translation of some viral proteins and some eukaryotic proteins. It would block assembly/maturation steps of some viruses, and interfere with translation in eukaryotic cells. It would interfere with release of newly formed viruses from a host cell, but not affect eukaryotic cells. It would interfere with protein synthesis in bacteria, but not affect eukaryotic ribosomes. It would interfere with mRNA transcription in bacteria and viruses, but not affect eukaryotic transcription.In terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show: A microbe is the aetiological agent of a disease A gene encodes a product that contributes to disease A gene encodes a product that contributes to immunity to a disease A mutation does not contribute to diseaseWe have many antimicrobial drugs to treat bacterial infections, but very few for viruses. Why is it so difficult to treat viral infections? Hint: What would the targets for the drugs be?
- Below, you can see a picture of an antimicrobial drug. Regarding semi-synthetic antimicrobial drug development to try to avoid development of antibiotic resistance, use 1 sentence to address what is the significance/value of the presence of the various R-groups (e.g. R4, R5, R6, etc.)?‘’Viruses cannot be grown in standard microbiological culture such as broth and agar. They need to be cultured in the presence of a suitable host such as prokaryotic cells (easiest to grow in the lab), plants and animals because they are unable to reproduce independently in living cells’’.2.2 What are the changes that are brought by a virus to a cell?
