Different techniques of Staining.

Question

Accepted Answer

Staining techniques are used to enhance the visibility of microorganisms under a microscope.

Gram staining: Differentiates bacteria into Gram-positive and Gram-negative based on cell wall composition.
Acid-fast staining: Identifies acid-fast bacteria like Mycobacterium tuberculosis.
Endospore staining: Highlights endospores produced by certain bacteria.
Capsule staining: Visualizes the protective capsules surrounding some bacteria.
Flagella staining: Stains the flagella used for bacterial motility.
Hematoxylin and eosin staining: Commonly used in histology to differentiate cell types.

Accepted Answer

1 Simple staining

2 Gram statining ( differential staining) -for diffrenciate gram positive and gram negative bacteria.

Acid fast staining - Distinguishes acid fast bacteria such as mycobacterium species from non-acid-fast bacteria.
Endospore stain - demonstrate spore structure in bacteria as well as free spores
Capsule stain - demonstrates presence of capsules surrounding cells
Flagella stain - demonstrates presence and arrangement of flagella
Cytoplasmic inclusion stains - Indentifies intracellular deposits of starch, glycogen, polyphosphates, hydroxybutyrate and other substance
Giemsa stain - Particularly applicable for staining rickettsias and some protozoa
