Textbook Question
Chapter 22, Problem 2EQ
Bacillus thuringiensis makes toxins that kill insects. These toxins must be applied several times during the growth season to prevent insect damage. As an alternative to repeated applications, one strategy is to apply bacteria directly to leaves. However, B. thuringiensis does not survive very long in the field. Other bacteria, such as Pseudomonas syringae, do survive. Propose a way to alter P. syringae so it could be used as an insecticide. Discuss advantages and disadvantages of this approach compared with the repeated applications of the toxins from B. thuringiensis.

You have isolated a beta-lactamase producing Staphylococcus aureus (not a MRSA strain) from an
infected surgical site on your patient.
If for genetic reasons, your patient is allergic to all antibiotics except beta-lactam antibiotics such as
ampicillin ( they can only take Beta-lactam antibiotics such as ampicillin), which strategy below
could
you use to treat this Staphylococcus aureus infection in your patient? Note different answers
compared to previous question.
give the patient erythromycin
can use a beta-lactamse resistant beta-lactam such as methicillin or oxacillin
O give the patient penicillin
give the patient an azole drug
The world is facing a Corona Virus (COVID-19) Pandemic and as a potential scientist and a
microbiology student, you have been required to prepare the easiest and most affordable hand
sanitizer that can be utilized by students in various microbiology laboratories. Each student in your class has been given 96% ethanol and you are required to prepare 70% ethanol hand
sanitizer in a 2L spray bottle. Describe clearly the method you will use in order to achieve the aim of the practical.

- One of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap. Why is this not proof that Bacillus anthracis cells have both an S-layer and a capsule simultaneously?

Explain your answer. What is the mode of action of bacitracin? How does this influence the types of bacteria it can be used against effectively? What is the mode of action of tetracycline? How does this influence the types of bacteria it can be used against effectively? Describe how populations of bacteria can evolve resistance to antibiotics. In your description, use the terms/phrases: mutation, resistant, sensitive, individuals, populations, natural selection, horizontal gene transfer.arrow_forwardTRY TO KEEP IN SHORT AND USE OWN WORD FOR THIS QUESTION You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?arrow_forward
- The synthesis of arginine by Nuerospora was determined by examining a number of mutant strains that were unable to synthesize the compound. Use the table of bacterial growth below to 1) determine the correct sequence of the synthesis pathway and 2) where in the synthesis pathway each mutation interrupts the synthesis.

- Imagine that you have set up a Kirby Bauer experiment on Mueller Hinton agar (non-selective agar) in order to test if Escherichia coli is susceptible or resistant to Drug X. After 24 hours, you notice a zone of inhibition (clear zone) around your antibiotic disc and determine that E. coli is susceptible to Drug X. You then take a cotton swab and subculture a sample from this zone of inhibition (where no growth was apparent) onto a new agar plate without antibiotics and after 24 hours you see growth of E.coli. What can you conclude about Drug X?arrow_forwardWhat are two possible reasons for choosing a bacteriostatic treatment over a bactericidal one?

The presence of this bacterium in the nose and throat is widespread in the population, and in most people, colonization with Strep. pneumoniae is asymptomatic. The figure attached shows a comparison of in vitro growth curves of the wild-type strain of Strep. pneumoniae, as well as a Strep. pneumoniae mutant strain with a defect in one bacterial gene. The graph on the right shows the growth curve following addition of lysozyme during the logarithmic phase of bacterial growth. Which statement could account for the data in these graphs? Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that cannot modify its peptidoglycan to be lysozyme-resistant. Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that that expresses increased levels of LPS.
