Since heat fixation is not required and cells are not subjected to the distorting effects of chemicals and heat, their natural size and shape can be seen.
Also, it makes it possible to view hard to stain bacteria such as spirilli.

∙ 9y agoWhen observing cells under a microscope it is usually very difficult to observe cells and sub-cellular features without stains. Negative stains are background stains that are typically used to provide contrast for visualization when the primary sample cannot be stained.

Is uranyl acetate a negative stain?
Yes, uranyl acetate is used as a negative stain in electron microscopy.
What kind of stain would you use to visualize Sars?
Negative stain
What are the advantages of the simple stain technique over the negative stain technique?
Negative staining has a dark contrasted background and the bacteria is white. Simple staining has a white background and bacteria is the color depended on your stain color.Negative staining when prepared is NOT heat fixed but simple staining when prepared is heat fixed. Heat fixed means when preparing slide with bacteria on it, it is passed over some type of flame, like a Bunsen burner flame, three times or four times.
What color is Gram- stain?
Gram- negative bacteria turns red to pink after the gram stain is performed.
What is the gram stain of enterobacter cloacae?
Negative
What is the gram stain for cholera?

Is HIV gram stain positive or negative?
The answer to whether HIV gram-stain positive or negative is that HIV gram-stain is negative. They retain the light red or pink color after the stain.
What kind of stain would you use to visualize Sars?
Negative stain
Why is the technique called negative staining?
Because the cell wall repels the binding of the negative stain therefore the cells do not stain. Because of this the background is stain with the dye used and the bacteria remain colorless. Basically your staining the background, that is, you are not directly staining the cells.
Why is the size more accurate in a negative stain than a simple stain?
since you do not heat fix the slide when you use a negative stain the cells do not shrink or become distorted
What does a negative result for a spore stain indicate about the organism?
A negative result for the spores stain indicate that the gram-negative organism is present. A positive result for a spore stain indicates that a gram positive organism is present.
