Question

Quizplus · Accepted Answer

The Gram stain, acid-fast stain, and endospore stain are all differential stains, which means they allow differentiation between different types of microorganisms based on the staining outcome. The Gram stain differentiates between Gram-positive and Gram-negative bacteria, the acid-fast stain is used to detect mycobacteria, and the endospore stain is used to distinguish between endospores and vegetative cells. The other options are not true for all three stains, as not all of them require heat, charge of the cell wall may not always affect staining outcome, and some may not be used on a wet mount. Negative stain technique is not used for any of the three stains.
