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