abstract：:The presence of cholesteryl glucosides and high levels of lysophospholipids are elements making the cell wall of Helicobacter pylori unique. In this study, we have investigated the relationship between lysophospholipid content and cholesteryl glucoside composition of variants of 6 clinical isolates. The samples were c...
