In microbiology, capsules are structures made of a slimy layer known as polysaccharides or glycoproteins. These capsules are found surrounding the cell wall of certain bacteria, such as Streptococcus pneumoniae and Bacillus anthracis. The purpose of capsules is to provide protection to the bacteria from environmental threats, including desiccation and the host’s immune system. Capsules also facilitate bacterial adherence to surfaces and can enhance the bacterium’s ability to cause disease. In laboratory settings, capsules can be visualized using special staining techniques, such as the India ink method or capsule staining, which help microbiologists identify and characterize different bacterial species.
