Abstract

The glycolipid that characterizes the majority of isolates of Mycobacterium bovis and that has come to be known as M. bovis-identifying lipid is the phenolic glycolipid mycoside B described in the literature by others. However, when mycoside B obtained from M. bovis BCG, field isolates, and infected tissues was examined in detail, it was shown to be different from that described in the literature in some important respects. In particular, the glycosyl substituent is 2-O-methyl-α-L-rhamnopyranose rather than 2-O-methyl-β-D-rhamnopyranose. With this information, a seroreactive neoglycoprotein (neoantigen) containing the 2-O-methyl-α-L-rhamnopyranosyl substituent suitable for the serodiagnosis of bovine tuberculosis was synthesized. M. bovis also contains other minor seroreactive phenolic glycolipids, one of which is a deacylated form of mycoside B and another of which contains an α-L-rhamnopyranosyl unit rather than 2-O-methyl-α-L-rhamnopyranose.
