negative staining is when the micro-organism on slide is not stained.. instead the rest of the material on the slide gets stained and the organism stands out prominently unstained.. this occurs because that organism has a thick capsule around it which is non-stainable with that stain.. example is pneumococci staining with India ink.

Why can treponema denticola be seen with negative staining?
Because it is a Gram-negative bacterium and can be stained with Gram-negative stain.
Is a coverslip used during negative staining?
No, a coverslip is not typically used during negative staining. In negative staining, the specimen is mixed with a contrast dye that stains the background rather than the specimen itself, allowing the cells to stand out against the dark background. This technique is often performed directly on a microscope slide without a coverslip to preserve the morphology and details of the specimen.
What shape are gram negative bacteria?
Gram negative bacteria are typically rod-shaped (bacilli) or corkscrew-shaped (spirochetes). They have a double cell membrane composed of an inner and outer membrane, which contributes to their staining properties in the Gram staining technique.
What is a negative stain?
A negative stain is a type of staining technique used in microbiology where the background surrounding the specimen is stained dark, leaving the specimen colorless and transparent. This method is particularly useful for visualizing certain microbial structures that may be difficult to see using other staining techniques.
What is the other name for Negative staining?
Negative staining is also known as indirect staining because the stain does not directly interact with the specimen.
Is the classification of cyanobacteria based on Gram staining positive or negative?

Why can treponema denticola be seen with negative staining?
Because it is a Gram-negative bacterium and can be stained with Gram-negative stain.
What types of organisms are subjected to Negative Staining Technique?
Bacteria .
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.
What microbes are negative?
