- Is is best to observe slides of bacteria stained with the acid fast stain under high dry magnification. True or falseThe 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.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 False
- The 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 cultureWhich 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.why is it necessary to employ a spore stain rather than rely on diagnosis of sporing from examination of gram stain
- Out of the three gram-positive bacteria (Micrococcus luteus, Staphylococcus aureus, and Staphylococcus epidermidis). Which of the following test(s) will help me identify the unknown gram-positive bacteria? Gram Stain Wet Mount (motility testing) Endospore Staining Acid Fast Staining Differential & Selective Media (MacConkey, PEA, EMB, MSA Agar, Blood Agar, etc.) Oxidative-Fermentative Test Carbohydrate Fermentation MR-VP Testing Indole Production Citrate Utilization Triple Sugar Iron Testing Catalase TestWhy 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?
