/tei·cho·ic ac·id/ (ti-ko´ik) any of a diverse group of antigenic polymers of glycerol or ribitol phosphates found attached to the cell walls or in intracellular association with membranes of gram-positive bacteria; they determine group specificity of some species, e.g., the staphylococci.

But two molecules successfully blocked the early-stage gene and hindered teichoic acid production.
Teichoic acids and O-specific polysaccharides may be used as adhesins by Gram-positive and Gram-negative bacteria, respectively.
This has been attributed mainly to the abundance of teichoic acids in the Gram positive peptidoglycan layer and the fact that the peptidoglycan layer in Gram negative bacteria is hidden behind the outer membrane which has a lower binding capacity (Beveridge 1988).
