Why is the gram stain technique more valuable than the simple stain technique in the diagnostic laboratory Under what circumstances might the simple stain be preferable to the gram stain technique?
There are two types of stains, the simple stain and the differential stain. A simple stain colors all objects the same while a differential stain is used to spot differences in microorganisms. A gram stain is a differential stain, which is used to tell the difference in gram negative and gram positive bacteria. A simple stain would stain all the organisms the same and this difference would not be noted. You would be able to determine their shape, whether it is a cocci or bacillus (rod), but not the type. I'm not sure why the simple stain would be preferable unless you just wanted a quick answer as to the shape of the bacteria. In some cases, a wet prep can be made of a presumptive gram positive cocci to tell the difference between bacteria or yeast. Otherwise, I would say that the gram stain is the only way to go.
What is the conclusion of a gram stain of purple rods and cocci through a microscope?
This is a Gram Stain. If the technique was proper, the red rods are Gram-negative and the purple cocci are Gram-positive. This staining technique is used to help identify various bacteria. The Gram-positive bacteria that are purple hold the stain due to it's layered cell membrane. It contains a peptidoglycan layer that acts as a lattice trapping the crystal violet-Iodine dye complex.
If Congo red is used instead of safranin in the gram stain technique what would happen?

How would you describe the gram stain?
Describe the Gram stain technique and the effect on Gram-positive and Gram-negative bacteria after each step. Be very specific about what is happening at each step and why it happens. (hint: be sure to fully explain your answer and not just list the steps)
What would you expect from a gram stain done on a slide that was heated too hot during the heat-fixed smear?
A Gram stain refers to a staining technique for the identification of bacteria. A Gram stain done on a slide that was heated too hot during the heat-fixed smear will destroy the cell wall of the bacteria.
What is determined of the Gram Stain?
A gram stain is a cow
Why do all cells stain purple in the flagella stain but not in the gram stain?
The gram stain uses a decolorizing product so it is possible to differentiate between the gram and the gram cells. Gram positive cells stain purple in color.
Theories of principle of gram stain reactions?
Gram stain
What is the gram stain for cholera?
Gram Negative
Can a Gram stain a prion?
Protists are often stained using a silver stain, not a Gram stain.
What bacterial staining technique is it when a basic dye is utilized to stain bacterial cells?
A basic dye used in gram staining is crystal violet.
What is the gram stain of H5N1?
The Gram stain is used for bacteria and not for viruses.
