front 1 A Smear for the capsule requires heat-fixing. | back 1 False |
front 2 The basic stain (Maneval's) is applied and remains for five minutes. | back 2 False |
front 3 What is the purpose for the Congo red stain? | back 3 It stains the background. |
front 4 What is the purpose of the Maneval's stain? | back 4 It colorizes the cell proper |
front 5 Nigrosin can be used in place of Congo red. | back 5 True |
front 6 This stain is both a structural and differential stain. | back 6 True |
front 7 Identify 3 species of bacteria that may have capsules. | back 7 Bacillus anthracis, streptococcus pneumoniae, Klebsiella pneumoniae |
front 8 The rinsing agent in the Schaeffer-Fultron Method of endospore staining is | back 8 DI water |
front 9 The stain is both a structural and differential stain | back 9 True |
front 10 The primary stain in the endospore stain is: | back 10 malachite green |
front 11 What color are the vegetative cells in the endospore stain? | back 11 red |
front 12 Heat is not necessary using the Schaeffer-Fulton method. | back 12 False |
front 13 A hood is necessary using the Schaeffer-Fulton method | back 13 True |
front 14 Identify 2 genera that have endospores. | back 14 Bacillus and Clostridium |
front 15 Match the location of the endospore with the descriptive term. | back 15 Subterminal endospore- The endospore is between the middle and end of the cell.
|
front 16 This stain is both a structural and differential stain | back 16 False |
front 17 Match the flagella arrangement to the definition: | back 17 Amphitrichous- Flagella at both ends of the bacterium.
|
front 18 Why can't flagella be observed in a living sample? | back 18 Bacterial flagella are too thin to be observed with the light microscope and ordinary stains. They need to be overstained and this kills them unfortunately. |
front 19 Organisms with a capsule and endospores are easy to destroy. | back 19 False |
front 20 All staining methods used in all the staining exercises performed in lab always color or stain the microbe. | back 20 False |
