Some bacteria are enclosed within a capsule. This protects the bacterium, even within phagocytes, helping to prevent the cell from being killed. Encapsulated bacteria grow as 'smooth' colonies, whereas colonies of bacteria that have lost their capsules appear rough.

Bacteria possess a number of structures that allow them to attach to target surfaces or tissues. Many bacteria are surrounded by a capsule, which is composed of polysaccharides and glycoproteins. The capsule is important in bacteria that cause disease because it prevents phagocytosis by the host's white blood cells.

The capsule of bacteria may be penetrated by structures arising from the cell wall or plasma membrane such as cell wall specific polysaccharide, cell wall teichoic acid, plasma membrane lipoteichoic acid, flagella and pili...
