What is differential stain?
A differential stain is a type of staining technique used in microbiology to differentiate between different types of bacteria or cellular structures based on their physical and chemical properties. Examples of differential stains include the Gram stain and acid-fast stain.
What so endospore stain have in common with the acid-fast stain?
One thing that endospore stains have in common with the acid fast stain is that heat primary stain penetration. Another thing that endospore stains have in common with acid fast stains are counterstain.
A structural stain is considered to be a differential stain?
A differential stain is a type of stain that distinguishes between different types of microorganisms or structures based on their physical or chemical properties. Structural stains, like the Gram stain or acid-fast stain, target specific structures within cells to differentiate between them.
Why do you use acid fast stain?
Because it is a type of stain that uses contrasting (in this case the presence or absence of a stain) color to determine what type or classification the organism is. Differential = determining between different groups; you are staining to differentiate one group from another by classifying the organisms' ability to quickly resist decolorization by acids.
What type of dye is used to stain the specimen when the acid-fast stain and the gram stain are used?
Both processes use 2 stains. The Gram staining process uses crystal violet as the primary stain and safranin as the secondary stain. Acid-fast staining uses carbol fuchsin as the primary and methylene blue as the secondary.

What is secondary stain?
A secondary stain is Methylene blue. This type of stain is used in a acid fast staining. This type of staining test can determine medical conditions such as tuberculosis.

What is an acid-fast pathogen?
An acid-fast pathogen is a bacteria that is harmful to humans. They have cell walls that contain mycolic acid which is a lipid. Common Gram type staining techniques wont work with these cells. A special stain carbolfuchsin is used to penetrate the wall.After staining you wash with acid alcohol if the stain remains it is acid fast if it washes out it is non-acid fast.Mycobacterium tuberculosis is a well known acid-fast pathogen
What type of lipid can keep a microorganism from drying out?
Mycolic acid helps these cells survive desiccation and makes them difficult to stain. Organisms with mycolic acid are acid fast.
What is a acid fast disease?
Some diseases are leprosy ( M. leprae), tuberculosis (M. tuberculosis), and nocardiosis ( N. brasiliensis, N. asteroides). The acid fast stain is important in identifying bacteria in the genus Mycobacterium and Nocardia.M. tuberculosis
What general type of stain is used to separate types of bacteria based on their cellular structure?
differential
Describe the mechanism of action for acid-fast stain?
ACID FAST Os Contains waxlike lipoidal material affecting staining quality. Carbolfuchsin is primary stain. Acid fast organisms resist decolorization with acid alcohol. After decolorization, methyelene blue is added to organisms to counterstain any material that is not acid fast. It is used for examination of Mycobacterium. The principle of staining is depend on the resistance of this type of bacteria to decolarization by acid alcohol, because the cell wall contain waxy material (mycolic acid) which prevent the removal of carbol fuchsin from the cell. Staining Procedure 1. Flood the slide with strong carbol fuchsin and heat until steam rises (but do not boil). 2. After 3-4 min apply more heat until rises again; do not let the stain dry on the slide. 3. About 5-7 min after the first application of heat washes the slide thoroughly under running water. 4. Decolourize in acid-alcohol until all traces of red have disappeared from the film. Decolourization should not be attempted in one stage; there should be intermittent washings in water and re-application of acid-alcohol. 5. Wash well with water and counter stain with Methylene blue for 1 min. 6. Wash and stand end to drain. 7. Acid-fast organisms are red, other organisms are blue.
