The role of capsular material in bacterial virulence & bacterial aggressins
Some pathogenic microorganisms (bacilli of anthrax, Clostridium perfringens, S. pneumoniae, causative agents of plague and tularaemia) are capable of producing a capsule in animal and human bodies. Certain microorganisms produce capsules in the organism as well as in nutrient media (causative agents of rhinoscleroma, ozaena, and pneumonia).
