  what is the difference between a simple stain and a differential stain?	A differential stain is a specific type of staining that allows for microbe identification, and distinguishing between cells in a mixed sample. This is very different from simple staining techniques that simply add color and contrast to a slide. Simple staining involves adding a basic, cationic dye to the organism.	The advantage of using stains to look at cells is that stains reveal these details and more. The arrangement of cells within a tissue reveals the health of that tissue. Multiple stains can used simultaneously to mark different cells by different colors.	Fungi, including yeast, may also be detected with a Gram stain. A Gram stain is typically ordered along with a culture when a bacterial or sometimes fungal infection is suspected. It is also usually performed when the result of a culture is positive, on a sample of the bacteria grown in the culture.

On the other hand, stain actually soaks into the concrete.	large amounts of cells in a smear can cause staining artifacts because stain is not washed away by destaining agents or water. ... heat fixation causes cells to adhere to the slide during staining. However, structures such as capsules can undergo shrinkage during heat fixations and can be lost in staining procedures.	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 negatively charged chromophores in acidic dyes are repelled by negatively charged cell walls, making them negative stains.
