Abstract:
The microbial flora in adult advanced periodontitis lesions is comprised of Gram-negative rods, with Bacteroides gingivalis as one of the major representatives. This review deals with biological properties of surface antigens, hemagglutinin (attachment factor), and capsular structure of B. gingivalis. Sera containing high IgG antibody levels to B. gingivalis enhanced the complement-mediated bactericidal activity in vitro, although the susceptibility to complement-mediated lysis differed among B. gingivalis strains. The protective effect of immunization against B. gingival is infection was exam

Abstract:
The ability of Bacteroides gingivalis 381 to attach to hydroxyapatite (HA) beads, treated with either human type I or type IV collagen, or to particles of bovine bone collagen was studied. All preparations were blocked with human albumin prior to being incubated with 3H-thymidine-labeled B. gingivalis 381 cells. The presence of collagen on HA surfaces (C-HA) significantly promoted attachment of the organism. HA treated with Type IV collagen bound B. gingivalis cells more effectively than did HA treated with type I collagen. Attachment of two additional strains of B. gingivalis to HA was also p

Abstract:
Gene banks of chromosomal DNA from Bacteroides gingival is 381 were constructed utilizing the bacteriophage replacement vector λCharon4A. A clone encoding a protein antigen from B. gingivalis was identified by Western-blot screening, with use of antiserum induced to extracts of B. gingivalis cells. DNA fragments from the phage clone were subcloned into the plasmid vector pACYC184 to yield an immunoreactive clone. Cell extracts from the subclone reacted with antiserum against B. gingivalis, but did not react with antisera to B. asaccharolyticus, B. intermedius, or B. melaninogenicus. The antise

Abstract:
The study was designed to compare the adherence of several Bacteroides species to A. viscosus. Using 3H, we labeled 24 laboratory strains, including 13 Bacteroides species and I I fresh clinical isolates of three Bacteroides species. Their adherence to A. viscosus bound to a saliva-coated mineral surface was quantified by liquid scintillation. Adherence relative to a standard strain, B. gingivalis 2561, was compared. Among the lab bacteroides, those of B. gingivalis (eight strains) were the greatest binders (mean, 80.5 ± 12.4%). Strains of other lab bacteroides bound less well (mean, 33.4 ± 6.

Abstract:
B acteroides gingivalis has been recognized as a pathogen causing adult periodontal disease. In this study, we examined the culture supernatants of B. gingival is for their ability to alter the function of polymorphonuclear leukocytes (PMNs). After a 60-minute incubation with the culture supernatants of B. gingivalis, it was found that there was a significant reduction of f-methionyl-leucyl-phenylalanine (FMLP) receptor in human and guinea pig PMNs. Superoxide anion (O- 2) production of PMNs stimulated by FMLP was also suppressed when cells were pre-incubated with the culture supernatants of B

Abstract:
ABSTRACT The complete 2,343,479-bp genome sequence of the gram-negative, pathogenic oral bacterium Porphyromonas gingivalis strain W83, a major contributor to periodontal disease, was determined. Whole-genome comparative analysis with other available complete genome sequences confirms the close relationship between the Cytophaga-Flavobacteria-Bacteroides (CFB) phylum and the green-sulfur bacteria. Within the CFB phyla, the genomes most similar to that of P. gingivalis are those of Bacteroides thetaiotaomicron and B. fragilis. Outside of the CFB phyla the most similar genome to P. gingivalis is

Abstract:
A Bacteroides gingivalis adhesin mediating attachment to red blood cells and buccal epithelial cells was isolated, cloned and characterized. The isolation procedure involved gentle stirring of the cells followed by ammonium sulphate precipitation, ion-exchange and gel chromatography. The native molecule had a Mr in excess of 10⁶ kDa and was made up of subunits with an Mr of 43 kDa. Antisera raised to the adhesin and its subunits reacted with antigens on the surface of B. gingivalis cells. No reaction with fimbriae was seen. The IgG fractions from these antisera inhibited the adherence of B. gi

Abstract:
Two proteases, P-1 and P-4, present in the outer membranes of Bacteroides gingivalis ATCC 33277, were isolated and partially purified by SDS-PAGE. The purification procedures resulted in a specific activity 45-fold (P-1) and 40-fold (P-4) greater than that of the crude fractions. Electrophoresis of proteolytically active P-1 produced three bands corresponding to molecular weights of 235, 220 and 200 kD whereas electrophoresis of proteolytically active P-4 produced one major band corresponding to 74 kD. The optimum temperature and pH for activity were determined using N-∂-benzoyl-D-arginine-p-n

Abstract:
Abstract Three major forms of periodontal disease have been described in HIV-infected patients: linear gingival erythema (formerly HIV-associated gingivitis), necrotizing ulcerative periodontitis (formerly HIV-associated periodontitis), and acute necrotizing ulcerative gingivitis. Gingivitis refers to inflammation of the gingivae caused by oral microflora; when associated with changes in the bone it is referred to as periodontitis. Acute necrotizing ulcerative gingivitis involves inflammation of the gingiva with soft tissue necrosis, but not bone loss. Some investigators have suggested that HI
