Question

Quizplus · Accepted Answer

A bacterial capsule is a specialized structure that is composed of a thick, gelatinous material that surrounds the bacterial cell. This structure is often able to protect the bacteria from the host's immune system by preventing phagocytosis (the engulfment and destruction of bacteria by immune cells). Capsules also provide bacteria with protection against desiccation, and can aid in attachment to surfaces.
