Streptococcus pneumoniae are Gram-positive bacteria normally found in the upper respiratory tract including the throat and nasal passages. Streptococcus pneumoniae is characterized by a polysaccharide capsule that completely encloses the cell and plays a key role in its virulence. The cell wall of S. pneumoniae is composed of peptidoglycan with teichoic acid attached to every third N-acetylmuramic acid. Lipoteichoic acid is attached via a lipid moiety, and both teichoic and lipoteichoic acid contain phosphorylcholine. Two choline residues may exist on each carbohydrate repeat, which is important to S. pneumoniae because the choline adheres to choline-binding receptors located on human cells.
