Rhizobia are gram-negative bacteria which have on their surface a high amount of polysaccharides. The more important sugars are the exopolysaccharides (EPS), capsular polysaccharides (CPS) and lipopolysaccharides (LPS). Rhizobia are symbiotic nitrogen-fixing bacteria which infect the roots of leguminous plants. Bacterial competition, infection of the plant by the bacteria, nodule formation and fixation efficiency are processes that depend heavily on the intense exchange of molecular signals between symbionts and the polysaccharides are believed to play a major part in this. Serological techniques have been used extensively in rhizobia identification. Although these are limited to those strains that crossreact within a given serogroup, common serological reactions indicate, in general, a certain degree of surface similarity which may be related to physiological characteristics. Serology can also be used in competition assays and for identification of bacteria inside the leguminous root nodule. In this study, we investigated the possibility of the polysaccharide being recognized by the antiserum prepared with whole cells wich are commonly used to identify bacteria and also compare the response of bacteria and polysaccharide. The two antisera (antiBR-33 strain of B. japonicum and antiBR-96 strain of B. japonicum and antiBR-96 strain of B. elkanii) were allowed to react with homologous and heterologous polysaccharides. The homologous recognition was at least 100 times stronger than the heterologous one. Both... MenosRhizobia are gram-negative bacteria which have on their surface a high amount of polysaccharides.
