Title: Immunological studies of an artificial antigen with specificity of a common polysaccharide antigen of Pseudomonas aeruginosa. Author: Makarenko TA, Kocharova NA, Edvabnaya LS, Tsvetkov YE, Kholodkova EV, Knirel YA, Backinowsky LV, Kochetkov NK, Stanislavsky ES. Journal: FEMS Immunol Med Microbiol; 1993 Oct; 7(3):251-6. PubMed ID: 7506094. Abstract: Synthetic D-rhamnan, with the structure of Pseudomonas aeruginosa common polysaccharide antigen (CPA), was conjugated with BSA. The artificial antigen obtained, and the natural antigens, lipopolysaccharides (LPS) of P. aeruginosa and Pseudomonas cerasi with rhamnan chains of the same structure, were studied by ELISA with rabbit antibodies to the D-rhamnan-BSA conjugate and to the P. cerasi O-antigen. Immunological relations between the LPS of P. aeruginosa and P. cerasi determined by CPA as well as between these LPS and D-rhamnan-BSA were revealed by ELISA. O-antiserum to P. cerasi possesses protective activity in the mouse passive protection test when mice are challenged with some P. aeruginosa strains; the antiserum to the D-rhamnan-BSA does not possess protective activity in mice.[Abstract] [Full Text] [Related] [New Search]
