Nothing except the cells would get stained. Hopefully, you are speaking of making a thin prep and then putting them on a slide. That's the only way you do gram stains. Stained slides are then studied for various things.

∙ 12y agoThat question just showed up on my microbiology quiz and the TA was jokingly saying "I wonder how many people got that one right", so it kinda made me think it might be a trick question. After thinking about it more, the only thing I could come up with is that human cheek CELLS should show gram negative, as all human cells are gram negative and gram positive cell LPS invokes an immune response in humans. However, if the quiz had said cheek SWAB, you might see positive results from some of the bacteria living in your mouth in biofilm etc. He still hasn't given us an answer but that's all I can think of.

∙ 11y agonothing will happen because human cell has no cell wall which means they are lack of peptidolycan layer so if you stain with primary stain (crstal violet) it would wash out.

What happens if you use gram stain on a virus?
Most likely nothing. The gram stain will only stain the peptidoglycan cell wall of bacteria. Most viruses have a protein coat called a capsid. The capsid will not take up either the crystal violet or the safranin of a Gram stain.
Are human cells gram positive?
Human cells are Gram-negative because they do not contain certain structures. More simply, if they don't have a cell wall they cannot be Gram-positive.
What is the gram stain for measles virus?
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
Can you tell an organisms gram stain by simple staining?
Gram stain is not a simple stain because simple stains do not use two or more stains. Gram stain is a differential stain differentiating between Gram positive (blue-black) and Gram negative (pink-red).
If you have isolated a prokaryotic cell the first step in identification is?
gram stain

What is the result of gram stain on human cell?
Human cells have no cell walls, only a plasma membrane, and as a result lack the peptidoglycan layer that gram stains utilize to differentiate between gram negative and gram positive species of bacteria. Therefore, human cells are unable to retain the crystal violet introduced in the first step of the gram stain, and stain negative. (they appear pinkish like gram-negative bacteria)
Can you gram stain a cell without a cell wall?
No bacteria exist without a cell wall! If they loose cell wall then they die. Gram staining is used to differentiate gram positive (that doesnt have outer membrane) and gram negative (cell wall+outer membrane) bacteria.
Are human cells gram positive?
Human cells are Gram-negative because they do not contain certain structures. More simply, if they don't have a cell wall they cannot be Gram-positive.
What is the difference between gram-positive and gram-negative bacteria?
The presence of thick cell wall. Gram positives have a thick cell wall and remain blue. Gram negatives have a thin cell wall where the blue stain washes out and then will stain pink with the counter stain.
What is the Gram stain for measles?
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
What is the gram stain for measles virus?
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
Does the gram stain procedure work for all bacteria?
Yes. The gram stain procedure separates all bacteria into one of two groups - into gram-negative bacteria which do not stain purple and into gram-positive cells which do stain purple. In structural terms, the ability of a cell to become stained during the gram stain procedure is due to the chemical makeup of the cell wall.
Are polymers gram negative?
A gram stain tests the contents of the cell wall. Polymers do not have cell walls.
Can you tell an organisms gram stain by simple staining?
Gram stain is not a simple stain because simple stains do not use two or more stains. Gram stain is a differential stain differentiating between Gram positive (blue-black) and Gram negative (pink-red).
What causes a stain to adhere to bacterial cells?
In a gram positive stain it is because the cell's cell wall is made up of peptioglycan
What is the arrangement of echoli cell under gram stain?
e. coli stains Gram negative.
