Cross-reactions of lipopolysaccharides of Pseudomonas aeruginosa in antipneumococcal and other antisera.
Lipopolysaccharides of the seven Fisher immunotypes of Pseudomonas aeruginosa gave cross-precipitation in many antipneumococcal sera. The reaction of Pseudomonas type IV in type 25 antipneumococcal serum was immediate and heavy: 93 micrograms of antibody nitrogen per ml. Correlations are described, mainly between the structures of the O-chains of the immunotypes and their specificities as shown by the cross-reactions.
