Capsule, Flagella, Pili (Fimbriae), Glycocalyx (Slime Layer)

Capsule, Flagella, Pili (Fimbriae), Glycocalyx (Slime Layer) Capsule The capsule is a gelatinous layer covering the entire bacterium. It is composed of polysaccharide, except in the anthrax bacillus, which has a capsule of polymerized d-glutamic acid. The sugar components of the polysaccharide vary from one species of bacteria to another and frequently determine the serologic … Read more Capsule, Flagella, Pili (Fimbriae), Glycocalyx (Slime Layer)

Cell Inclusion Bodies

Cell inclusion Bodies

Cell inclusion Bodies Bacterial cell inclusion bodies are otherwise known as granules. Electron microscopic observation reported the presence of both organic and inorganic granules inside the bacterial cell. These granules function as energy storage and these are also involved in reducing osmotic pressure. Some of these granules are found freely moving in the cytoplasm (polyphosphate, … Read more Cell Inclusion Bodies
