Differential staining is the procedure that are used to distinguish organism based on their staining properties. Use of gram stain divide bacteria into two classes - gram positive which retain crystal violet stain purple colour, gram negative which lose their crystal violet and give pink colour. By this method we can differentiate two different types of bacteria having different cell wall composition that is the reason gram staining used widely as differential staining

What is the purpose of differential staining?
differential staining is a staining technique used to stain colorless bacteria against a dark background.
What color is Gram- stain?
Gram- negative bacteria turns red to pink after the gram stain is performed.
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).
What is the primary stain used in Gram staining?
The primary stain used in Gram staining is crystal violet.
Is cytomegalovirus a gram positive or negative?
Cytomegalovirus (CMV) is a DNA virus and is not classified as either gram positive or gram negative. Gram staining is a technique used to classify bacteria based on their cell wall structure, and it does not apply to viruses like CMV.
Who developed Gram staining?
Gram staining was devised by Hans Christian Gram of Denmark in the 1800s. (1853-1938)
A method called Gram staining is used to tell what?
Gram staining is primarily used to differential bacteria based on their cell wall structure. Bacteria are usually classified as Gram positive or Gram negative. Gram positive - thick layer of peptidoglycan as outermost layer, plasma membrane as innermost layer. Gram negative - thin layer of peptidoglycan "sandwiched" in between 2 separate plasma membranes.
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 mordant is used in the process of gram staining?
The mordant used in the process of gram staining is called crystal violet.
Are cyanobacteria classified as gram-negative bacteria?
Yes, cyanobacteria are classified as gram-negative bacteria. This classification is based on the structure of their cell walls, which contain a thin layer of peptidoglycan surrounded by an outer membrane. When stained using the Gram staining technique, cyanobacteria appear pink or red under a microscope, indicating that they do not retain the crystal violet stain and are therefore gram-negative.
