Abstract

Sera from 100 patients not infected with Serratia marcescens at the time of hospital admission lacked detectable H-immobilizing antibodies against all 20 currently recognized H-antigens of this microorganism. However, various patient sera revealed elevated titers of O-agglutinins against several of the 20 O-antigens of S. marcescens, in a particular O-antigens, O1, O3, O4, O5, O7, O8, O10, O11, O16, O17, O18, O19, and O20. Rabbit anti-Shigella serogroup B immune serum cross-reacted with S. marcescens O-antigens O1 and O10; anti-Shigella serogroup C serum cross-reacted weakly with S. marcescens O-antigen O8. Conversely, rabbit anti-S. marcescens O1 and O10 immune sera cross-reacted with a clinical isolate of Shigella flexneri. None of the anti-S. marcescens O1-O20 rabbit immune sera reacted with commercial febrile antigens of Salmonella serogroups A, B, C1,2, D, E1,2,3,4, Brucella abortus, Francisella tularensis, and Proteus OX19. However, a reference strain of Salmonella typhi (9;d,-) was agglutinated by anti S. marcescens anti-O8 and O10 sera, a reference strain of S. paratyphi B (4,5;-,-) weakly by anti-S. marcescens O8 serum, and a reference strain of S. paratyphi C (6,8;-,-) by anti-S. marcescens anti-O10 and O16 rabbit imm...Continue Reading

Antibodies: Agglutination

Antibody-mediated agglutination is the clumping of cells in the presence of antibody, which binds multiple cells together. This enhances the clearance of pathogens. Find the latest research on antibody-mediated agglutination here.
