Gram staining is important because to differentiate between gram positive and gram negative
Gram staining is done to determine
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.
Gram staining was devised by Hans Christian Gram of Denmark in the 1800s. (1853-1938)
list the steps of the gram staining procedure
Gram's Iodine acts as a mordant in gram staining.
A basic dye used in gram staining is crystal violet.
No. It is a staining on the cell itself.
Gram stain is used to determine whether the cell is gram positive or negative. Gram positive is when the cell has very thick layers of peptidoglycan, and gram negative when the layers are thin. In the staining process, those that decolorize easily are gram negative, and the one that retain the primary stain are gram positive. The acid fast staining is a techique that stains only the gram positive and only the genuses of mycobacterium, nocardia, and actinomycetes.
Cultures that are older have the possibility to turn from Gram Postive to Gram Negative thus altering the results of the Gram staining test.
Gram staining is the way for people to get knowledge about their specimen , if it is gram negative or gram positive. Gram positive have thick walls and stains purple, gram negative has thin walls and will turn pink after gram staining and bacteria with spores and endospores will show up clear or see through because it cant stain with gram staining dye.
To determine if bacteria is gram positive or gram negative
Gram negative bacilli
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
Gram negative bacteria stain red or pink because of the retaining counter staining dye (Safranin).
Neither. Polio is a virus and is not affected by gram staining.

Pink- Gram negative Purple-Gram positive :)
if you don't establish gram staining reaction and morphology in the identification of the bacterial isolate, you won't know the gram staining reaction properties and morphology identities of the bacterial isolate.

Gram Positive Rods
In males, gram staining may be sufficient to diagnose chlamydia. In women, it is not sufficient, as other non-pathogenic diplococci may have the same gram stain.
