It uses a solu"on of posi"vely charged dye including: crystal violet, safrain, methyleneblue or fuchsin to adhere to and stain the nega"vely charged membrane of themicroorganism. Simple stain. You could use any of the following: methylene blue, crystalviolet, safranin or fuschin.Your Answer:5 / 5 ptsQues!on 18You suspect a pa"ent may have TB. Once a sample has been obtained, it is sent offtothe lab for an acid-fast stain. If the pa"ent were infected with TB, describe what youwould expect to see on the stained slide.If the pa"ent were infected with Mycobacterium Tuberculosis (TB), I would expect tosee the red dye carbolfuchsin stained cells, the acid fast protec"ve membraneremaining red indica"ng that the pa"ent has TB, and the rest of the non-acid fastbacterium to appear blue as they are counterstained.You would expect to see red cells (TB+) on a blue background (TB nega!ve).3 / 3 ptsQues!on 19True or False: If a pa"ent is suspected of having malaria, a Giemsa stain would be anappropriate differen"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 ptsQues!on 20Iden"fy what type of electron microscope was used to capture the following imageand 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 treatedand layered in preserva"ves and put in between the electron beam source and thedetector. The image is the created as a result of the interac"ons of the electrons asthey 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!llvisible. The image lacks the outside ‘shell’ only appearance of SEM.Quiz Score: 97out of 100"PreviousNext#Submission Details:Time:46 minutesCurrentScore:97 out of100Kept Score:97 out of100HomeModulesGrades
