A. A biohazard.

B. A biofilm.

C. A cavity.

D. A bacterial party.

Gram-positive Bacteria

Gram-positive bacteria have thick, multi-layered peptidoglycan composed of a sugar backbone and peptide side chains cross-linked by transpeptidase. After gram staining, the Gram-positive cell wall loses some of its large chunky peptidoglycan cell walls but keeps enough of it to retain the purple color or primary stain. This principle distinguishes gram-positive bacteria from gram-negative bacteria that do not retain the primary stain of purple color. The gram-negative gets decolorized and takes the counterstain colored reddish to pink.
