What is a bacterial capsule?
Quick Answer
A bacterial capsule is a protective outer layer outside the cell wall of some bacteria. It can help them evade the immune system and resist drying out.
The Full Story
A capsule is a sticky, often sugary coating surrounding some bacteria. It can help protect cells from drying, help them attach to surfaces, and make it harder for immune cells to engulf them. Capsules are important virulence factors in several disease-causing bacteria. They can also make colonies appear mucoid in the laboratory.
