Bacterial capsule: It is typically a hydrated polysaccharide complex that covers the outermost part of the cell wall and is composed of monosaccharides joined together by glycosidic linkages in most bacteria.
Role of bacterial capsule:
They keep phagocytosis from ingesting and destroying the bacterial cell.
Capsules make the bacterial surface constituents slippery.
Allowing germs to adhere to surfaces and hide from the immune system by mimicking host tissues,
Making them resistant to complementing their invasiveness.
The capsule protects the cell from desiccation and harmful byproducts.
