| characterization of cross-reacting serotypes of campylobacter jejuni. | some strains of campylobacter jejuni react with more than one reference antiserum from the serotyping scheme based on heat-stable lipopolysaccharide antigens. to investigate the molecular basis of these cross-reactions, lipopolysaccharides from the reference strains for serotypes 4, 13, 16, 43, and 50 and isolates recovered during two different outbreaks of c. jejuni enteritis were analyzed by passive haemagglutination and sodium dodecyl sulphate-polyacrylamide gel electrophoresis coupled with s ... | 1989 | 2472859 |
| comparison and correlation of neisseria meningitidis serogroup b immunologic assay results and human antibody responses following three doses of the norwegian meningococcal outer membrane vesicle vaccine menbvac. | the prediction of efficacy of neisseria meningitidis serogroup b (menb) vaccines is currently hindered due to the lack of an appropriate correlate of protection. for outer membrane vesicle (omv) vaccines, immunogenicity has primarily been determined by the serum bactericidal antibody (sba) assay and omv enzyme-linked immunosorbent assay (elisa). however, the opsonophagocytic assay (opa), surface labeling assay, whole blood assay (wba), and salivary antibody elisa have been developed although cor ... | 2006 | 16861642 |
| elisa test for antimeningococcal igg and igm antibodies: application to epidemiology and diagnosis. | we have developed an enzyme-linked immunosorbent assay (elisa) in order to quantitate antimeningococcal igm and igg serum antibodies. the b:15 meningococcal strain was used as coating antigen, and class specific antibodies were detected by using alkaline phosphatase labelled rabbit anti-human igm or igg as conjugate. the specific igg activity was higher in sera from healthy meningococcal carriers than non-carriers, but the difference was not statistically significant. antimeningococcal igm serum ... | 1992 | 1589725 |
