What is the mordant in a gram stain?
Gram's iodine stain is applied after the culture is stained with the primary stain. It acts as a mordant, fixing the primary stain to the cell wall while lending no additional colour to the cell (i.e. the mordant itself is not a stain). The mordant is only able to fix the stain to Gram-positive bacteria because of the characteristic thick, peptidoglycan coat that they possess. Because the mordant is not able to fix the stain to Gram-negative bacteria (who's coat have a different composition), the crystal violet stain will wash away from Gram-negative bacteria when the decolourizing agent is added.
Why is safrinin used in gram staining?
as a couterstain
What is the staining process for separating bacteria?
This is known as a gram test.
What is the value of gram staining?
Gram staining is highly valuable. It allows us to identify two widely different bacteria. Gram staining can tell you if the bacteria is pathogenic or if a penicillin pill can cure it. It tells us gram-positive bacteria, or gram-negative. Positive being easily combated bacteria and some even helpful, and gram-negative being primarily pathogenic.

Who developed Gram staining?

What is the difference between flagella and axial filaments?
* the flagella is a project as strand while the axial filaments are spirochetes. * flagella : move cell by propeller like action , axial filaments : snake-like movement. flagella : present in gram (+)and gram (-) , while the filaments only in gram (-) . both of them have the same function
Why gram staining classified as differential staining?
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

Why is gram staining important?
It tells the microbiologist/clinician facts about the cell wall construction of the bacterium. This then indicates which antibiotics to prescribe if you are trying to get rid of a bacterial infection.

Is sporosarcina gram positive?
Yes, Sprosarcina is gram positive. It also has flagella (halophilia)
Is gram staining special staining?
yes it is a special staining like other types....its importance is that one can identify the type of bacteria........
