- Is is best to observe slides of bacteria stained with the acid fast stain under high dry magnification. True or falseIn the image attached is a unknown bacteria lab. The gram stain result and growth result is already given to us and is shown. What other tests (1-2 examples) could we use to follow up this test. Explain why we should use those tests with justification.The unknown observations are shown as a mixed stain, gram positive, and gram negative. The next images shows the chart of what we can choose from for the gram positive bacterial stain. We are allowed to choose 4 test or stains that we would like to use to preform to identify the unknown.
- Which of the following are true about a differential stain. There may be more than one answer! No chemicals are needed. More than one stain is used The acid fast stain is an example The Gram stain is an example.Peptidoglycan on bacterial cell walls is stained by crystal violet dye and for this reason those bacteria with a thick layer of peptidoglycan have purple appearance in gram dye/stain test. True FalseThe first step in identifying an unknown bacterium is to __________. The first step in identifying an unknown bacterium is to __________. culture your unknown on selective media perform endospore staining on your culture prepare a pure working stock simple staining on your culture acid-fast staining on your culture

What does Gram staining reveal owing to its use in clinical diagnosis? Indicate color staining results of gram positive and negative bacteria for every hypothetical scenario. Modification in Procedure Staining results 1. Crystal violet was replaced with methylene blue. G+ G- 2. Mordant was skipped G+ G- 3. Decolorizing step was omitted G+ G- 4. counterstain was not used? G+ G- 5. Crystal violet and safranin was swapped in position. G+ G- What bacterial specimen represent the following: (a) positive simple staining; and (b) negative simple staining viewed under OIO.

- First step : Below I have attached the image of gram stain. -We need to find the name of the compound. And after that , what possible test can be performed to find the compound. We need to do 6 test . So can you please help me with the names for the test to be performed to find the compound. Thank you so much ?Why is it important to limit the quantity of cells used to prepare a smear? Mark all that apply: O So that cells are not clumped and don't entrap stain creating erroneus results So that no contaminants are introduced onto the slide by being entrapped in clumps OSo that the cells are spread out enough that cell morphology can be discerned OSo that the cells are spread out enough that the arrangement can be observed O So that there are small groups of cells clumped together to make them visible Microsoft Bing 11:31 AM 87°F Sunny 9/14/2021You have performed an experiment and your aim is to obtain pure colonies. However, you observe some colony variations and you need to verify that this is not due to contamination, name and describe the staining method would you use to achieve this goal?
