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 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 is the best use of negative staining?
size and shape
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 is the definition of negative staining?
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 was koch's recommemdation for fixing and staining important for microbiology?
Koch's recommendation for fixing and staining is important for microbiology even though all bacteria can be seen under the microscope, because staining and fixing is needed in order to see inside of a transparent bacteria.
What is the other name for Negative staining?
Capsule Stain
What is the best use of negative staining?
size and shape
Why can treponema denticola be seen with negative staining?
Because it is a Gram-negative bacterium and can be stained with Gram-negative stain.
Disadvantages of staining cells?
There are many disadvantages to stain and not staining cells before viewing them. One disadvantage of gram staining is that the cells cannot be alive while being stained, so viewing live stained cells is impossible.
What types of organisms are subjected to Negative Staining Technique?
Bacteria .
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 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?
Those which show pink colour in gram staining are gram negative bacterialike E.coli
