Humoral immune response in human pulmonary tuberculosis: antibodies against Mycobacterium tuberculosis polysaccharide, protein and glycolipid antigens.

Sera from 67 tuberculosis patients and 30 healthy subjects have been analyzed for the presence of specific antibodies against polysaccharide, protein and glycolipid antigens from H37Rv strain of Mycobacterium tuberculosis. The results proved the advantages of using the glycolipid antigens in diagnosing tuberculosis as well as the relationship between the antibodies level and the extension of the pulmonary tuberculous lesions.
