Step by step
Solved in 3 steps
- The World Health Organization (WHO, 2017) haslisted six steps individualscan take to prevent and control the spread of antibiotic resistance. a.One of the recommendations is “Never demand antibiotics if your health worker says you don’t need them.”Explain why when you have a flu, your health care worker would say that you do not need antibiotics. What are the other five recommendations?Target: Antibiotic: Tetracyclive (TE) Antibiotic: _Ciprofloxacin (Cip) Target: Antibiotic: Penicillin (P) Target: Antibiotic: Trimethoprim sulfa Target: Antibiotic: Polymyxin B (PB) Target: Antibiotic: Steptomycin (5) Target:In antibiotics, define the terms bacteriostatic and bacteriocidal. What are the mechanism of action and resistance of beta-lactam antibiotic. What are the mechanism of action for one antibiotic effective against methicillin-resistant S. aureus (MRSA).
- A suspected pathogen is observed from the blood of a diseased mouse. An investigation of the other mice in the area indicates that it is not present in healthy mice. With Koch's postulates in mind, what is the next step to determine whether or not this suspected pathogen is the cause of disease in the mouse? a) Grow the suspected pathogen in a pure culture Ob) Re-isolate the suspected pathogen and show that it is the same as the original pathogen c) Inoculate a healthy mouse with the suspected pathogen O d) Determine whether the organism in the pure culture is the same one as in the original sampleAs part of your job in an international pharmaceutical company you are given the task of: a) Developing a cheaper method for the production of vitamin C b) Developing a live cholera vaccine Describe how you would accomplish these tasksWhy is antibiotic resistance a problem and how can antibiotic resistance be prevented? (List the 7 methods for preventing resistance.)
- What is a relevant biological process that can be used to briefly explain or illustrate the risks associated with antibiotics?We 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?Discuss why it is important for us to conduct research at the basic level of physiology in order to better understand what makes Mycobacteria latent or grow during an infection so that we can design new and/or better treatment modalities.
