GlossaryGram-negative bacteria

have a thin peptidoglycan layer and an outer membrane

Gram-negative bacteria are a group of bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Instead, they appear red or pink after a counterstain is applied. This is due to their unique cell wall structure, which has a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides. This outer membrane can make them more resistant to antibiotics and more likely to cause certain types of infections.
