What color is gram-negative stain?
Red or pink. Gram Positive = Purple or Violet, Gram Negative = Red or Pink. I just think of the mnemonic Positive-Purple both starting with P.
What would be the result of over destaining on gram-positive types?
Over destaining can cause the purple color from the gram positive bacteria to be washed away, so when you apply the safrinin the gram positive bacteria will take up a pink color causing gram positive bacteria to appear gram negative.
What is Gram staining method used for?
the purpose is to determine diffrent kinds of bacteria based on their results. if it'sgram positive the color will be pink and if it is gram negative the color will be red.
What is the appearance of gram negative bacteria after addition of mordant in the gram stain?
Red/pink
What gram stain that purple cocci and pink rods means?
it is talking about different colors different types of bacterium turn when stained a certain color depending on cell wall/membrane thickness 'purple cocci' is referring to a round bacteria which in this case thick cell wall/membranes because of its darker color, 'pink rods' is referring to rod or stick-like bacteria which in this case have thin cell wall/membranes because of their color the darker the stain color is on the bacteria/cell/protist/etc. the thicker the wall/membrane is

What color is gram?
Gram- negative bacteria turns red to pink after the gram stain is performed.
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.
What color is Gram- stain?
Gram- negative bacteria turns red to pink after the gram stain is performed.
What color is neg?
Gram- negative bacteria turns red to pink after the gram stain is performed.

What does gram negative on a serratia marcescens gram stain mean?
Bacteria are gram positive or gram negative. Serratia happens to be a gram negative bacteria. They appear pink on a gram stain. Gram positive bacteria stain to a purple color on a gram stain. We can classify and ID bacteria using their gram stain and shape. Some antibiotics only work on gram negative bacteria and some only work on gram positive bacteria. It helps a doctor know which antibiotic to use.

What is the Red gram?
Gram-negative bacteria Gram-negative bacteria have an outer membrane. However, they have a thinner peptidoglycan cell wall. This means they do not hold the blue dye used in Gram testing and do not appear blue. Instead, they appear red or pink in color.
What color is gram negative stain and gram positive stain if you forget to apply iodine?
If iodine is not applied, both the gram-positive and gram-negative stains will appear to be gram-negative. The iodine acts as a mordant that helps to fix the crystal violet stain in the gram-positive bacteria, making them appear purple. Without iodine, the crystal violet stain can be easily washed out of both gram-positive and gram-negative bacteria, resulting in a pink or red color.
What color is proteus vulgaris?
it can be gram negative or gram positive; which the color would be pink or purple.
What are the differences between gram positive and gram negative bacteria?
The cell walls are the difference. Gram stain will be positive, as the cell wall is thicker. Gram-positive bacteria retain the (crystal violet) dye. Then a decolorizer will be added and then the pink counterstain. This will give all gram-negative bacteria a red or pink coloring. All the steps are done for all cultures being Gram stained and when they grow, the color will be seen as well as the shape.
