We have learned terms like 'sterile,' 'commensal,' 'contaminants,' 'germs,' 'microorganisms,' and 'infection' over the last week and in the lab. Why is it important for a health care personnel to clean the surface of a patient's skin before drawing a blood sample? Why is it important for a health care personnel to change his gloves and sanitize his hands between patients?

You have learned many different techniques so far this semester that allow us to identify pathogenic microbes in the clinical setting. Why do you think rapid methods are so helpful? Why are traditional tests such as metabolic tests not always used to ID clinically important microbes?
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?

What will pose an ethical issue in these procedures are performed - mutilation, sterilization?
-For each item listed below, select a sterilant that you feel is the most suitable and effective for that item. Discuss why you selected each sterilant.? A) plastic Petri dishes to be used for nutrient media B) glass tubes of bacterial cultures to be discarded C) sterile milk D) dozens of reusable glass pipets E) bone tissue for grafting F) room air G) hospital mattresses H) biopsy tissue for histology analysis I) plastic respiratory therapy equipment and arthroscopes J) vaccines
why is it important that you disinfect your work area both before and after working with bacteria?
Why is it important to use sterile practices when working with microorganisms?
Unlike a disinfectant, an antiseptica) sanitizes objects rather than sterilizes them.b) destroys all microorganisms.c) is non-toxic enough to be used on human skin.d) requires heat to be effective.e) can be used in food products.
There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiple the series of dilutions together to find the final dilution value. If 3 serial dilutions are performed, each with a value of 0.01, what is the cumulative dilution? Express your answer as an exponent, e.g. 0.1 would be 1e-1 and 0.01 would be 1e-2
Aseptic technique refers to A) the microbial inoculum placed into a test tube or onto a Petri plate. B) a series of practices to avoid contamination. C) the autoclave and other sterilizing procedures. D) cleanliness in the laboratory.
there are different methods to be used in order to control opportunistic infection and that includes cleaning, sanitizing, disinfecting, sterilizing... And that depends how they can be applied according to the area and level the health care worker or scientist is and the environment. Do you know how these methods of microbial growth are applied and where?
