- This is a Microbiology question about blood culture analyzers such as the BactecWhat is the process a technician takes if the analyzer alarms for a positive bottle?What action(s) are taken if there are no organisms seen in the Gram Stain made from that bottle?You are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative. 9) What makes the bacteria Gram negative?10) Approximately how long would it take you to finish the entire procedureThis is multipart for the SAME question so please answer ALL The data below are gram stains after collecting 3 samples of bacteria from different places, pet, sink, and table. A. Out of the three, which one is gram(+), explain B. Out of the three, which one is gram(-), explain C. Out of the three, which one is not pure culture, explain D. You did not do an ethanol rinse on you “table” sample gram stain, how does this change the answers above, explain
- Can someone help with microbiology? I believe the top indicates a gram negative bacteria but the hue looks orange to me.For a laboratory exercise of basic techniques in microbiology: Gram stain and Microscopy. What is the answer of tableYou are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative. 6) What would be the last reagent you use to identify the bacteria? 7) What type of visual aid you need to help you see the bacterial samples clearly? 8) After the use of what reagent, you will be able to decide if you have a Gram positive or Gram negative bacteria? **Please give the answer**
- Hello, this is microbiology, and the lab was about pure culture techniques.Staining microbes are important techniques to characterize microbes in any microbiology laboratory.in your opinion which of the four staining procedures is the most important .in your answer be specific why u chose that technique. Please make this explanation as short as possible .thank you.MICROBIOLOGY: Microscopic Morphology of Microbes Write your introduction (This includes principles, significance of the study, objectives of the experiment and how the objectives were achieved. This part must also be in the passive voice and past tense. Introduction must be short but packed with relevant content). another: What is the advantage of the Gram stain over the simple stain? What is the theory about the mechanism of the Gram-stain reaction?
- You collected a sample from a patient with a suspected STI. After Gram staining, you observed this under the microscope. What can you conclude about this microbial agent? Also I have attached a pictureHello, please answer the following Microbiology question correctly and fully. Please explain your answer. Question: Why is it necessary to inoculate the KIA medium all the way down to the bottom of the tube during inoculation? (What's different about the top and the bottom of the tube?) *If you correctly answer the question correctly, I will provide a Thumbs Up to you. Thank you.The acid fast bacterium, Mycobacterium smegmatis, is relatively safe for students to work with because of its thin cell wall. If a gram stain is to be performed on this particular microbe, it often takes the gram stain reaction. Why?
