      • Capsules help the organism adhere to host cells. The capsule also facilitates and maintains bacterial colonization of biological (e.g. teeth) and inanimate (e.g. prosthetic heart valves) surfaces through the formation of biofilms. Capsule also acts as receptors for bacteriophages.

    A given bacterial species may undergo a phenomenon called S-R variation, whereby the cell loses the ability to form a capsule. Some capsules are very large and absorb water; bacteria with this type of capsule (e.g., Klebsiella pneumoniae) form mucoid (M) colonies.

    Mar 13, 2024 · In bacteria, polymers known as capsules are generated at the periphery of the cell wall, enveloping the entire cell. Capsules connect to the peptidoglycan in Gram-negative bacteria or the plasma membrane in Gram-positive bacteria via covalent attachments to either phospholipid or lipid-A molecules.

    It is a virulent factor because it enhances the ability of bacteria to cause a disease by preventing phagocytosis. In addition, it has ben shown that this structure protects bacteria from being entrapped, and killed it, by NET.
