Monoclonal antibody for identification of Bacteroides gingivalis lipopolysaccharide.
A monoclonal antibody, BBG-25, raised in BALB/c mice demonstrated specificity for Bacteroides gingivalis lipopolysaccharide. Immunoblotting indicated that this monoclonal antibody does not cross-react with lipopolysaccharide prepared from enterobacterial organisms or from other Bacteroides species.
متن کاملGlycylprolyl dipeptidylaminopeptidase from Bacteroides gingivalis.
Dipeptidyl aminopeptidase activity was found in the culture medium of Bacteroides gingivalis 381. The enzyme, hydrolyzing glycylprolyl-4-methylcoumaryl-7-amide, was purified 750-fold from culture medium by ammonium sulfate precipitation, Sephadex G-200 gel filtration, and DEAE Bio Gel A column chromatography. The molecular weight, determined by gel filtration, was approximately 160,000. The iso...
متن کاملInteractions of Bacteroides gingivalis with fibrinogen.
Results of previous studies from our laboratory have shown that a strain of Bacteroides intermedius isolated originally from a patient with acute necrotizing ulcerative gingivitis binds and degrades human fibrinogen (M.S. Lantz, L.M. Switalski, K.S. Kornman, and M. Hook, J. Bacteriol. 163:623-628, 1985). We report that strains of Bacteroides gingivalis, an organism implicated in the etiology of...
متن کاملRapid presumptive identification and further characterization of Bacteroides forsythus.
Bacteroides forsythus is a fastidious anaerobic gram-negative organism associated with various forms of periodontal disease. It is dependent on N-acetylmuramic acid for growth. A method for rapid presumptive identification of human-derived strains of B. forsythus is presented, based on the following eight criteria: (i) positive activity for alpha-glucosidase, (ii) positive activity for beta-glu...
متن کاملRapid identification of Bacteroides fragilis with bile and antibiotic disks.
A simple screening test is described for separating Bacteroides fragilis from other anaerobic gram-negative bacilli. The test utilizes filter paper disks impregnated with 25 mg of oxgall (Difco), tested in conjunction with antibiotic identification disks. The bile disks and antibiotic disks are placed on a supplemented brucella blood agar plate which has been inoculated by swabbing with a stand...
