Teichoic acid is present in the cell wall of
Teichoic acids, which are polymers of polyribitol-phosphate, are cross-linked to the peptidoglycan and can be antigenic. They are impoant in cell wall metabolism. Antiteichoic acid antibodies detectable by gel diffusion may be found in patients with active endocarditis caused by S aureus.ComponentsGram-PositiveGram-NegativeColor of GramStained CellPurpleReddish-pinkRepresentativeGeneraBacillus,Staphylococcus,StreptococcusEscherichia,Neisseria,PseudomonasPeptidoglycanThick layerThin layerTeichoic acidsPresentAbsentOuter membraneAbsentPresentLipopolysaccharide(endotoxin)AbsentPresentPorin proteinsAbsentPresent; allow passage ofmolecules through outermembranePeriplasmAbsentPresentRef: Jawetz; 27th edition; Page no: 23
