Methods for producing capsular polysaccharide from a pneumococcus by maintaining pneumococcus in a growth medium, to alleviate a pneumococcal infection in an animal, to produce an immunogenic preparation for administration to an animal at risk of developing a pneumococcal infection, to produce pneumococcal polysaccharide and to assess whether a test compound is useful for alleviating pneumococcal infection in an animal

"METHODS FOR PRODUCING CAPSULAR POLISSACARIDE FROM A TIRE BY MAINTAINING THE TIRE IN A GROWTH MEDIUM, TO MINOR A PNEUMOCOCIC INFECTION TO PRODUCE A PREPARATION FOR THE IMUNOGENOUS DYNAMIC PREPARATION FOR AN ADENOGENIC DEVELOPMENT The invention relates to methods of modulating capsular polysaccharide production in pneumococci, such as Streptococcus pneumoniae. The invention further relates to methods for alleviating pneumococcal infections in animals, and methods of identifying both agents capable of modulating pneumococcal infections in animals. Figure 1, comprising Figures 1Ai-Avi and 1Bi-1Bvi, is a series of images indicating the effect of carbon dioxide concentration and environmental oxygen on colony morphology and capsule size as assessed using Quellung's reaction.
