Immunological Reactions between Dextran Polysaccharide and Some Bacterial Antisera
نویسنده
چکیده
Dextran, the synthetic polysaccharide produced by Leuconostoc mesenterioides from saccharose, reacts immunologically with antisera from pneumococci, some of the Sahnonella and some of the types of Streptococcus viridans (Bargen). This immunological relationship is independent of the specific antipolysaccharide antibodies of these sera, suggesting the existence of a distinct antibody produced by an active group of the specific bacterial polysaccharide, which is similar or identical to the active group of the dextran polysaccharide.

Anti-Leuconostoc mesenteroides sera have been produced in rabbits. These antisera gave precipitin reactions with relatively high dilutions of the homologous polysaccharide, dextran, having a maximum nitrogen content of 0.08 per cent. It can therefore be concluded that this dextran is a haptene.
متن کاملImmunological Reactions between Agar-agar and Some Bacterial Antisera
1. As found by Sordelli and Mayer, agar adsorbed on bacteria produces agar-reacting antibodies in animals injected with these organisms. 2. False cross-agglutination and precipitin reactions can be produced in sera containing agar-reacting antibodies by organisms grown on agar. Zozaya's publication in this field (3) requires partial revision on this account. 3. There is suggestive immunological...
متن کاملImmunological and structural relatedness of catabolic ornithine carbamoyltransferases and the anabolic enzymes of enterobacteria.
Purified catabolic ornithine carbamoyltransferase of Pseudomonas putida and anabolic ornithine carbamoyltransferase (argF product) of Escherichia coli K-12 were used to prepare antisera. The two specific antisera gave heterologous cross-reactions of various intensities with bacterial catabolic ornithine carbamoyltransferases formed by Pseudomonas and representative organisms of other bacterial ...
متن کاملAn immunological cross reaction between monkey gonadotrophin preparations and antisera to human gonadotrophins.
There is still some confusion about the ability of monkey and human gonadotrophins to cross react in immunological systems. McGarry & Beck (1963), using a haemagglutination inhibition technique, found a cross reaction between antisera to human fsh and monkey fsh. They also found a similar cross reaction with lh. Neill, Peckham & Knobil (1967), Bagshawe, Orr & Godden (1968) and Faiman, Ryan, Gre...
متن کاملCharacterization of the cross-reaction between type 19F(19) and 19A(57) pneumococcal capsular polysaccharides: compositional analysis and immunological relation determined with rabbit typing antisera.
The immunological relation, physicochemical characteristics, and chemical composition of type 19F(19) and 19A(57) within the cross-reactive group 19 pneumococcal capsular polysaccharides were studied. By using rabbit hyperimmune diagnostic antisera in agglutination, immunodiffusion, quantitative precipitation, and absorption assays, extensive cross-antigenicity and cross-immunogenicity were dem...
