Comparison of the Serological Reactivity of Lipopolysaccharides from Japanese and Western Strains of <i>Helicobacter pylori</i> to Sera from <i>H. pylori</i>-Positive Humans

<table>Immunoreactivities of two types of <i>H. pylori</i>-positive Japanese sera to <i>H. pylori </i>LPS from Japanese and Western strains.  The LPS used are shown in Figure <a href="../fig1/">1</a>.   Type A sera only reacted with LPS containing the highly antigenic epitope and Type B sera only reacted with LPS containing the weakly antigenic epitope. 1, NCTC11637-LPS; 2, Sydney strain-LPS; 3, 26695-LPS; 4, O:2-LPS, 5, GU2-LPS; 6, DU1-LPS; 7, CA2-LPS; 8, CA4-LPS; and 9, CA5-LPS.</table>
