Microbiology

A protective layer around a bacterial cell

In microbiology a capsule is a well-organised layer of polysaccharide (occasionally protein) deposited outside the cell wall of many bacteria, distinct from a looser slime layer. It shields the cell from desiccation and phagocytosis and is a major virulence factor, which is why encapsulated strains of organisms such as Streptococcus pneumoniae are more dangerous and why capsular polysaccharides are used as vaccines. It is a microbial coat, a construct unrelated to an organ's envelope or a pill's shell beyond the shared idea of an enclosing layer.[1]

The polysaccharide layer surrounding the bacterial cell wall
