What color and shape is serratia marcescens?
Gram negative, is motile, red pigment and is a bacillus shape
Why does the counterstain not change the color of all of the cells is it because the primary stain repels or masks the secondary stain?
In a gram stain the primary stain is crystal violet. Iodine then sets that dye into the gram positive cells while alcohol washes out the crystal violet from the gram negative cells. Then safranin, which is the counterstain in a gram stain, is used to dye the rest of the bacteria. This is the example I can give you of why a counterstain does not change the look in all the cells. Though safranin stains all the cells, the gram positive cells that were dyed purple from crystal violet don't look pink - only the gram negative do.
What is stained with primary dye?
Bacterial smears that are undergoing some type of differential staining method are stained with a primary dye. Primary dye typically refers to a Crystal-voilet stain that is used in the gram staining procedure to color all cells purple. After a mordant (iodine-makes the dye complex less soluble), decolorizer, and a counterstain are added to the primary dye, a person can view the slide under a microscope in order to distinguish gram-positive bacteria from gram-negative bacteria. The cell wall of gram-negative bacteria will not retain the primary dye and be washed away with the decolorizer. Gram-neg. bacteria will then take on the counterstain providing contrast between the two types of bacteria when viewed under a microscope.

Function of the counterstain in acid-fast?
The function of a counterstain in acid-fast stains is to dye the non acid-fast bacteria cells a different color than the acid-fast cells. With two different colors present on a slide, the contrast between the two types (acid-fast and non acid-fast) is more distinct. The more distinct view of cells will assist in observations of a slide.
