[IgG, IgA and IgM serum antibodies against lipopolysaccharide from Bacteroides intermedius in periodontal health and disease]. 1989

S Otake, and H Kato, and N Kurihara, and M Yamamoto, and T Kuroki, and M Makimura

Serum antibody titers to lipopolysaccharide from Bacteroides intermedius (B. intermedius) and Bacteroides gingivalis (B. gingivalis) were measured by enzyme-linked immunosorbent assay in serum samples from subjects with healthy gingiva and patients with periodontitis. The IgG antibody titers to LPS from B. gingivalis were significantly higher in the patients group, compared with healthy controls. No such difference was found between IgG activity to LPS from B. intermedius in the healthy and the periodonitis. Likewise, no significant difference in specific IgA level was found between the group with healthy gingiva and the patients group, both in LPS from B. intermedius and B. gingivalis. The IgM antibody levels to LPS from B. intermedius and B. gingivalis were low in subjects of patients and controls.

D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074 Immunoglobulin G The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B. Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D010518 Periodontitis Inflammation and loss of connective tissues supporting or surrounding the teeth. This may involve any part of the PERIODONTIUM. Periodontitis is currently classified by disease progression (CHRONIC PERIODONTITIS; AGGRESSIVE PERIODONTITIS) instead of age of onset. (From 1999 International Workshop for a Classification of Periodontal Diseases and Conditions, American Academy of Periodontology) Pericementitis,Pericementitides,Periodontitides
D000907 Antibodies, Bacterial Immunoglobulins produced in a response to BACTERIAL ANTIGENS. Bacterial Antibodies
D001439 Bacteroides A genus of gram-negative, anaerobic, rod-shaped bacteria. Its organisms are normal inhabitants of the oral, respiratory, intestinal, and urogenital cavities of humans, animals, and insects. Some species may be pathogenic.
