It uses a solu " on of posi " vely charged dye including: crystal violet, safrain, methylene blue or fuchsin to adhere to and stain the nega " vely charged membrane of the microorganism. Simple stain. You could use any of the following: methylene blue, crystal violet, safranin or fuschin. Your Answer: 5 / 5 pts Ques ! on 18 You suspect a pa " ent may have TB. Once a sample has been obtained, it is sent o ff to the lab for an acid-fast stain. If the pa " ent were infected with TB, describe what you would expect to see on the stained slide. If the pa " ent were infected with Mycobacterium Tuberculosis (TB), I would expect to see the red dye carbolfuchsin stained cells, the acid fast protec " ve membrane remaining red indica " ng that the pa " ent has TB, and the rest of the non-acid fast bacterium to appear blue as they are counterstained. You would expect to see red cells (TB+) on a blue background (TB nega ! ve). 3 / 3 pts Ques ! on 19 True or False: If a pa " ent is suspected of having malaria, a Giemsa stain would be an appropriate di ff eren " al test to perform. True Correct! Correct! Giemsa stains are o $ en used in the clinical se & ng to aid in the diagnosis of blood parasites. False Your Answer: 10 / 10 pts Ques ! on 20 Iden " fy what type of electron microscope was used to capture the following image and explain your choice. This image was captured by a Transmission Electron Microscope, or TEM microscope. I know this because a TEM microscope u " lizes hin slices of a sample, heavily treated and layered in preserva " ves and put in between the electron beam source and the detector. The image is the created as a result of the interac " ons of the electrons as they pass through the thin sec " oning of the sample. It is used to view substructures, subcellular organelles, and viral par " cles. The above image is captured via a Transmission Electron Microscope (TEM). Even at 20nm resolu ! on (inset image), subcellular substructures are s ! ll visible. The image lacks the outside ‘shell’ only appearance of SEM.
