- Consider the concept of empirical anti-microbial therapy. Why would a sputum sample have been collected before antibiotic therapy was commenced?explain in your own words an introduction to a lab about Control of Microbial Growth - Antimicrobic Sensitivity Testing Kirby-Bauer MethodDiscuss the general principles of antibiotic therapy.
- True or false panresistant organisms are only susceptible to the strongest of antibioticsMicrobiology Briefly describe any THREE CATEGORIES (three modes of action) of antibacterial drugs. Make sure to tell how they work and how bacteria have become resistant to them.Briefly describe the main scientific principle(s) underlying the following techniques used in the Combating Disease practical (you may use diagrams if you wish): ammonium sulphate precipitation Dialysis Immunoelectrophoresis
- Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is one experiment you could do, involving culturing the organism?Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario.

Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is a procedure you could do, involving making a slide of the organism?Your patient has a severe sore throat. A throat swab has allowed you to isolate the causative bacterium, which you subjected to a Minimum Inhibitory Concentration Test. For each of the antibiotics tested, you also know its therapeutic index. Whích would be the best drug to use to treat your patient? O Highest MIC and largest therapeutic index O Lowest MIC and smallest therapeutic index O Highest MIC and smallest therapeutic index O Lowest MIC and largest therapeutic index
- A patient is suffering from a bacterial pathogenic disease and you are given the patient's sample culture. As a clinical laboratory scientist, identify the 2 tests you would perform to identify the correct course of treatment. These tests have been taught in lab. Note: Identify the tests you would perform and NOT the disease or the specific drug to treat the disease.Attached below is the study about the effects of handwashing and the effectiveness of soap against bacteria. What conclusions can be generated from this result? A C before washing hands 10 second hand wash B D hot water only rinse 30 second hand wash Figure 8: Agar plates with bacteria A) before washing hands B) after rinsing hands in hot water C) After washing hands with soap for 10 seconds and D) after washing hands for 30 seconds. Images show that the number of bacteria on the plate are not greatly reduced after a hot water rinse or 10 second handwash but bacterial levels are reduced after a proper hand wash for 30 seconds.Describe the purpose of identifying unknown bacterial cultures in medical field. Name the step by step experiments/procedures that microbiologists follow in order to identify microorganisms.
