Study Notes
Glycocalyx
- A polysaccharide coating secreted by many bacteria.
- Covers surfaces like a film.
- Helps bacteria adhere to various structures such as skin, heart valves, prosthetic joints, and catheters.
- Important component of biofilms.
Medical Importance
- Glycocalyx-producing strains of Pseudomonas aeruginosa cause respiratory tract infections in cystic fibrosis patients.
- Glycocalyx-producing strains of Staphylococcus epidermidis and viridans streptococci cause endocarditis.
- Glycocalyx mediates adherence of Streptococcus mutans to the surface of teeth.
- Plays a key role in the formation of plaque, the precursor of dental caries.
