Question

Cells with this property have an endogenous viral gene that produces a structure analogous to viral “tail sheaths” containing TssA/TssB sheath around an Hcp tube. Cells with this property have S-layers directly bound to their membranes instead of to secondary polymers. Cells with this property contain compounds that consist of an O-antigen, (15[1])a core polysaccharide, and a Lipid A subunit. Cells with this property can use a “needle complex” or injectisome to export effectors across three membranes in the (*) Type III secretion system. The periplasm of cells with this property are enclosed by a characteristic diderm double membrane that contains lipopolysaccharides. (10[1])A fuchsin or safranin counterstain is used to visualize cells with this (-5[1])property. For 10 points, bacterial cells with what property have a thin layer of peptidoglycan, causing them to not retain a crystal violet stain? (10[1])■END■

ANSWER: gram-negative bacterial cells [accept bacteria with an outer membrane; accept diderm before mentioned; prompt on bacterial cells; prompt on GN]
