What is the value of gram staining?
Gram staining is highly valuable. It allows us to identify two widely different bacteria. Gram staining can tell you if the bacteria is pathogenic or if a penicillin pill can cure it. It tells us gram-positive bacteria, or gram-negative. Positive being easily combated bacteria and some even helpful, and gram-negative being primarily pathogenic.
What shape are gram negative bacteria?
Gram negative bacteria is shaped like rods and stained a reddish pink color due to the gram staining process. Gram negative bacteria do not form spores.
Why is it important to immobilize the bacteria on a slide prior to staining?
to view
Why is it important to follow the gram staining procedure?
This is simply important in order to have accurate staining results. If this is not followed, the process of the staining will result to false positives or false negatives.
Bacterial smears are fixed before staining to?
affix the cells to the slide and to kill bacteria

What is the purpose of differential staining?
differential staining is a staining technique used to stain colorless bacteria against a dark background.
Is gram staining special staining?
yes it is a special staining like other types....its importance is that one can identify the type of bacteria........
Is staining a material a physical change?
Staining is a chemical process.
Describe the microscopic appearance of encapsulated streptococcus if stained with safranin?
Safranin (red) is used in gram staining and endospore staining as the secondary stain. Nigrosin is used in negative staining, staining only the background and not the bacteria. Therefore, the bacteria within the capsule would stain red from the safranin. (Like in endospore staining and negative gram staining, safranin would stain the bacteria red.) Nigrosin would stain the background of the organism just as it would in negative staining. Bacteria (within capsul): stained safranin red Capsule (outer layer of bacteria): clear Background of organism: stained dark with Nigrosin
What types of organisms are subjected to Negative Staining Technique?
Bacteria .
Why is it important to immobilize the bacteria on a slide prior to staining?
to view
What staining procedure will be used to observe bacteria in the sputum sample?
acid fast staining or Ziel Neelson staining for observing Mycobacteria tuberculosis or Koch bacilli from sputum sample.
What happens if alcohol is omitted from the gram staining process?
If alcohol (decolorizing step) is omitted then the primary stain absorb by the bacteria will not be washed away. This will result in all or nearly all the bacteria to appear purple in color under the microscope.
Why is it imortant to immoblize the bacteria on the slide prior to staining?
to kill cells
Why was koch's recommemdation for fixing and staining important for microbiology?
Koch's recommendation for fixing and staining is important for microbiology even though all bacteria can be seen under the microscope, because staining and fixing is needed in order to see inside of a transparent bacteria.
