Abstract
The glycoconjugates with BSA (bovine serum albumin) were synthesized using a next saccharide: disaccharide derivative M.leprae PGL-1 (phenolic glycolipid-1); a complex of the disaccharide fragment and the branched hexasaccharide fragment LAM (lipoarabinomannan); diarabinofuranose fragment LAM. These glycoconjugates were used as antigenic components for leprosy rapid serotest construction in immunochromatographic format (leprosy LF serotest). The data obtained with sera of leprosy patients, patients who have been in contact with leprosy, and healthy donors indicate that the most promising antigenic component is a BSA conjugate with two synthetic epitopes - a disaccharide derivative of PGL-1 and a branched hexasaccharide fragment of LAM. The leprosy LF serotest with such glycoconjugate demonstrated the greatest diagnostic sensitivity for main forms of leprosy - paucibacillary (PB) and multibacillary (MB).
