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 are the names of special stains in microbiology?
In microbiology the concept of staining is very important because it highlights the structures of microorganisms allowing them to be seen under a microscope (because ordinarily the microorganisms are somewhat transparent making them difficult to see). In the case of some bacteria, many have specific surface structures such as capsules and flagella as well as internal components such as endospores. To specifically enhance these structures, a special stain may be used. An example of this is using negative staining techniques to see capsules, or using the Ziehl-Neelsen technique to see endospores.
What color is Gram- stain?
Gram- negative bacteria turns red to pink after the gram stain is performed.
What type of gram is H1N1 bacteria gram-positive or gram-negative?
neither...it is a virus, and gram-staining, a microbiology tool, is not used to help identify or classify a virus
What is the best use of negative staining?
size and shape
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?
The classification of cyanobacteria is based on Gram staining, which is typically negative.

Is the acid fast staining result positive or negative for the sample?
The acid-fast staining result for the sample is positive.
What are the advantages and disadvantages of positive ands negative staining for morphological study of bacteria?
Advantages: easy to carry out, natural shape and side Disadvatages: heat fixing can distorte cells, more attention needed
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.
