This document discusses capsule staining, which is a technique used to identify the presence of bacterial capsules under a light microscope. It begins by defining bacterial capsules and explaining their functions, which include helping bacteria resist phagocytosis and providing protection. It then discusses the principle of capsule staining, which uses a negative stain to contrast the unstained capsule against stained bacterial cells. The procedure involves smearing a bacterial culture onto a slide with negative stain, staining with a counterstain like crystal violet, and examining under a microscope for unstained capsules surrounding stained cells. Examples of capsule-containing bacteria that can be identified this way include Klebsiella pneumoniae and Bacillus anthracis. Read less. AI-enhanced description.

The bacterial capsule is a large structure common to many bacteria. It is a well-organized layer, not easily washed off, and it can be the cause of various diseases. The capsule—which can be found in both gram negative and gram-positive bacteria —is different from the second lipid membrane — bacterial outer membrane , which contains lipopolysaccharides and lipoproteins and is found only in gram-negative bacteria. When the amorphous viscid secretion that makes up the capsule diffuses into the surrounding medium and remains as a loose undemarcated secretion, it is known as a slime layer. Capsule and slime layer are sometimes summarized under the term glycocalyx. Most bacterial capsules are composed of polysaccharide , [4] but some species use other materials, such as poly- D-glutamic acid in Bacillus anthracis.
