Definition

Flagella staining is a technique used to visualize the flagella of bacterial cells under a microscope. Special stains are applied to increase the contrast and make the flagella visible.

2. The most common stains used for flagella include Ryu stain and Leifson stain.
3. Proper preparation of the bacterial sample, including fixing and mordanting, is crucial for successful visualization of flagella.
4. Flagella staining helps in identifying motility characteristics and differentiating between species of bacteria.
5. Errors in the staining process can lead to false positives or negatives, making technique accuracy important.
