Question

Quizplus · Accepted Answer

Staphylococci and streptococci are both gram-positive cocci, which means they have a thick peptidoglycan layer in their cell wall that absorbs the crystal violet stain in the Gram stain. Gram-negative cocci have a thinner peptidoglycan layer and an outer membrane, making them appear pink or red in the Gram stain. Gram-negative aerobic rods and cocci refers to a different group of bacteria, while anaerobic gram-negative cocci do not include staphylococci or streptococci.
