Heterogeneity of antibodies reactive with the dominant antigen of Actinobacillus actinomycetemcomitans.
The serotype b-specific carbohydrate antigen (SbAg) of Actinobacillus actinomycetemcomitans Y4 is reported to be the O antigen of lipopolysaccharide, and the highest titers of serum antibody reactive with A. actinomycetemcomitans in early-onset periodontitis (EOP) patients bind SbAg. These high titers of serum antibody reactive with SbAg are associated with a lesser extent and severity of perio...
متن کاملAntibody responses to capsular polysaccharide, lipopolysaccharide, and outer membrane in adults infected with Haemophilus influenzae type b.
The antibody response to Haemophilus influenzae type b antigens as capsular polysaccharide, lipopolysaccharide, and outer membrane components was studied by enzyme-linked immunosorbent assay in 10 adults infected with this bacterium. Almost all patients had detectable amounts of immunoglobulins G and M antibodies specific to capsular polysaccharide, lipopolysaccharide, or outer membrane in thei...

AIMS The aim of the present study was to determine whether or not lipopolysaccharide from Actinobacillus actinomycetemcomitans could stimulate arginase activity in a murine macrophage cell line (RAW264.7 cells). METHODS RAW264.7 cells were treated with A. actinomycetemcomitans-lipopolysaccharide or lipopolysaccharide from Escherichia coli for 24 h. The effect of polymyxin B, l-norvaline, dl-n...
متن کاملAntigenic heterogeneity of lipid A of Haemophilus influenzae.
The chemical structure and biologic function of the lipid A portion of lipopolysaccharide are not identical among gram-negative bacteria. This study indicates that antigenically heterogeneous lipid A exists among strains of Haemophilus influenzae. An immunoglobulin G3 murine monoclonal antibody, 3D2, produced against a nontypable H. influenzae strain 3524 has specificity for a site on the lipid...
متن کاملRelative avidity of serum immunoglobulin G antibody for the fimbria antigen of Actinobacillus actinomycetemcomitans in patients with adult periodontitis.
The relative avidity of serum immunoglobulin G antibody for the fimbria antigen of Actinobacillus actinomycetemcomitans was assessed by diethylamine dissociation enzyme-linked immunosorbent assay in patients with adult periodontitis. High-titer sera from patients not harboring A. actinomycetemcomitans had significantly higher avidities for the fimbria antigen than did high-titer sera from patie...
