Staphylococcus epidermis appears _________, whereas escherichia coli appears _________ after the gram stain.
BigorU [14]

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.

Staphylococcus is a Gram-Positive Bacteria i.e. it takes up the Gram stain.

Escherichia coli or E. coli is a Gram-Negative Bacteria i.e. it does not take up the Gram stain.

Gram Staining is done by immersing the bacterial sample in a solution of dye and then observing it under microscope after proper rinsing.

Gram Positive Bacteria are those bacteria that show a positive outcome on staining. Gram Positive Bacteria appear Stained after staining.

Gram Negative Bacteria are those bacteria that show a negative outcome on staining. Gram Negative Bacteria does not take up the stain and appear stainless.

The epidermis of Staphylococcus which is a Gram-Positive Bacteria appears to take up the stain whereas Escherichia coli which is a Gram-Negative Bacteria does not take up the stain.

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.
