In a simple stain, dyes that are either attracted by charge (a cationic dye such as methylene blue or crystal violet) or repelled by charge (an anionic dye such as eosin or India ink) are added to the smear. Cationic dyes bind the bacterial cells which can be easily observed against the bright background.

WebMethylene blue (MB) or methylthioninium chloride is a dye and drug that was first discovered in 1876 by Heinrich Caro and used to stain fabrics (Cooksey, 2024 ). This drug is approved by FDA to use for the treatment of methemoglobinemia, and as an effective suppressor for Tau protein aggregation ( Hosokawa et al., 2012 ).
WebBecause cells typically have negatively charged cell walls, the positive chromophores in basic dyes tend to stick to the cell walls, making them positive stains. Thus, commonly used basic dyes such as basic fuchsin, crystal violet, malachite green, methylene blue, and safranin typically serve as positive stains. On the other hand, the ...
