title: [Serological characteristic of lipopolysaccharides of Ralstonia solanacearum].
abstract: By immunochemical investigations of eight strains of Ralstonia solanacearum six strains were attributed to four serogroups. Two of them are formed by pairs of R. solanacearum strains 4 and 526; 758 and 7954; two others are represented by single strains--TX1 Ta TS3, correspondingly. Antigenic structure of R. solanacearum 7954 O-polysaccharide unites antigenic epitopes of R. solanacearum strains 4, 35, 526, 749, however the absence of cross-reactivity does not permit uniting them into the same group. The latter, and also the fact that the antiserum to R. solanacearum 749 in the reaction with LPS of R solanacearum 526 forms two precipitation lines (while in the homological system it forms only one line) may be explained by differences in the component composition of heat-stable immunogens (which were used for antiserum obtaining), and also purified LPS which were utilized as antigens in immunochemical reactions.
