To distinguish between acid fast positive and acid fast negative bacteria. Acid fast positive bacteria will stain red to pink color and acid fast negative bacteria will stain blue. Acid fast positive bacteria have mycolic acid in their cell wall, which will stain with carbol fuchsin and not decolorize with acid alcohol. Acid fast negative bacteria do not have mycolic acid in their cell wall, and become decolorize with the acid alcohol. Counterstain of methylene blue needs to be done in order to see the acid fast negative.

Is endospore staining differencial staining?
Yes, endospore staining is a type of differential staining. It is used to distinguish between bacterial endospores and the vegetative cells of the organism. The endospores appear as green structures against a pink or red background when using the Schaeffer-Fulton staining technique.
Why gram staining is 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
What diagnostic procedure used to detect corneal abrasions is known?
Fluorescein staining is the diagnostic procedure used to detect corneal abrasions. In this procedure, a special dye is applied to the eye, which highlights any damaged areas on the surface of the cornea under a cobalt blue light.
What staining procedure will be used to observe bacteria in the sputum sample?
A Gram stain is commonly used to observe bacteria in a sputum sample. This staining procedure helps visualize the bacterial cell wall structure and arrangement, aiding in the identification of different bacterial species.

Fontana silver staining.
What are the disadvantages of negative staining in microbiology?
It sometimes require additional chemical reagents to produce the desired action.
What is the purpose of mordant in a differential staining procedure?
The resultant crystal violet- iodine (CV-1) complex serves to intensify the-color of the stain. At this point, all cells will appear purple black.

What staining procedure makes use of pararosanaline?
The Schmorl's stain procedure makes use of pararosaniline as one of its staining components. It is a histological staining method used to highlight cellular structures in tissues.
What is the purpose of ethanol hydration in immunohistochemistry?
Ethanol hydration in immunohistochemistry is used to rehydrate tissue sections that have been dehydrated during the staining process. This step allows for better penetration of antibodies and reagents into the tissue, improving the overall staining quality and specificity.
