COMPOSITION COMPRISING BACILLUS CALMETTE GUERIN POLYSACCHARIDES AND BACILLUS CALMETTE GUERIN NUCLEIC ACIDS AND USE OF PREPARING MEDICAMENT THEREOF

摘要

A composition comprising Bacillus Calmette Guerin polysaccharides and Bacillus Calmette Guerin nucleic acids is provided, wherein said polysaccharides are comprising 10%-69% by mass of the composition and said nucleic acids are comprising 30%-89% by mass of the composition. The composition is made by mixing said polysaccharides and said nucleic acids, wherein said polysaccharides and said nucleic acids are obtained from the Bacillus Calmette Guerin cultures by the following process: extracting the mixture of said polysaccharides and said nucleic acids from said Bacillus Calmette Guerin cultures, and separating said polysaccharides and said nucleic acids from the mixture by ion exchange chromatography. The use of the composition comprising said polysaccharides and said nucleic acids for preparation of a biological medicament for treatment or prevention of microorganism infections, tumors, allergic reactions and the like is also provided.
