gram staining is a biochemical method of identifying bacteria in a more specific way.Thus it is important to differentiate gram positive and gram negative bacteria.

What is the stainning method called that can distinguish between two different types of eurobacteria?
I believe what you're looking for is the stain that can differentiate between Gram-negative and Gram-positive bacteria: two types of eubacteria. So the staining method is called the Gram method. Crystal violet will remain trapped in Gram-positive bacteria due to their thicker cell walls, causing them to stain purple. Crystal violet can be washed out of Gram-negative cell walls after alcohol treatment to remove their outer lipid membrane, and the cells can be counterstained with a red, positively charged stain. In the end, Gram-positive bacteria will look purple, and Gram-negative bacteria will look red. See Wikipedia for more details.
What is the gram stain for cholera?
Gram Negative
What is the difference between gram's stain and wright's stain?
Wright's Stain is a mixture of methylene blue and eosin in methanol. Gram's stain is crystal violet, iodine washed with acetone and proofed with a safranin dye to look for gram negative organism.
What is the name of the dye used in microscope slides?
The blue stain is called crystal violet. It can color the bacteria a blue color only if the cell wall is very thick. We then call that bacteria a Gram+ bacteria. Knowing the Gram test (+ or-) and the shape of the bacteria, we have a quick idea of what it might be. Then what antibiotic could be given gives a head start on a treatment. This can take as little as a few minutes. Further tests are usually done later on. They can take 24 to 36 hours to get a result.
What is the colony color ofr psuedomonas aeruginosa?
It depends upon the primary stain used. In Gram-staining the primary stain is Crystal Violet. P. aureus stains (and remains after decolorizing) purple which indicates that it is a Gram-positive bacteria.
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 gram stain of H5N1?
The Gram stain is used for bacteria and not for viruses.
What is the different reaction of Gram-negative and Gram-positive bacteria to Gram's stain testing?
Gram-positive bacteria which take up the stain turn purple, while Gram-negative bacteria which do not take up the stain turn red.
When treated with Gram stain Gram-positive bacteria appear?
Gram positive bacteria retain the violet stain, and appear purplish under a microscope.
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.
What color is Gram- stain?
Gram- negative bacteria turns red to pink after the gram stain is performed.
Why would you want to know if a gram stain is positive or negative?
Gram negative bacteria (pink gram stain) contain no outer cell membrane, while gram positive bacteria (purple gram stain) do contain an outer cell membrane. Gram negative and positive bacteria can respond differently to antibiotics. Many only work on only one of the two bacteria types. A gram stain is also the first step in identifying a bacteria, dividing bacteria into two large and distinct groups.
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.
Gram stain of the bacteria vibrio cholerae?
It's gram negative
What is the advantage of the gram stain over the simple stain?
gram staining differentiates between gram negative and gram positive bacteria by showing different colors. it shows blue or purple like color for gram positive bacteria and red color for gram negative bacteria. where as simple stain gives the same color to all the types of bacteria. hence it is difficult to differentiate between them.
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).
