Pasteurellaceae
Aggressive Periodontitis
Inflammation and loss of PERIODONTIUM that is characterized by rapid attachment loss and bone destruction in the presence of little local factors such as DENTAL PLAQUE and DENTAL CALCULUS. This highly destructive form of periodontitis often occurs in young people and was called early-onset periodontitis, but this disease also appears in old people.

Exotoxins
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.

Adhesins, Bacterial
Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE, BACTERIAL) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. What is sometimes called polymeric adhesin (BIOFILMS) is distinct from protein adhesin.
Aggregatibacter segnis
Mouth
Gingival Crevicular Fluid
A fluid occurring in minute amounts in the gingival crevice, believed by some authorities to be an inflammatory exudate and by others to cleanse material from the crevice, containing sticky plasma proteins which improve adhesions of the epithelial attachment, have antimicrobial properties, and exert antibody activity. (From Jablonski, Illustrated Dictionary of Dentistry, 1982)
Periodontal Attachment Loss
Loss or destruction of periodontal tissue caused by periodontitis or other destructive periodontal diseases or by injury during instrumentation. Attachment refers to the periodontal ligament which attaches to the alveolar bone. It has been hypothesized that treatment of the underlying periodontal disease and the seeding of periodontal ligament cells enable the creating of new attachment.

Virulence Factors
Those components of an organism that determine its capacity to cause disease but are not required for its viability per se. Two classes have been characterized: TOXINS, BIOLOGICAL and surface adhesion molecules that effect the ability of the microorganism to invade and colonize a host. (From Davis et al., Microbiology, 4th ed. p486)
Gram-Negative Bacteria
Epithelial Cells
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

Identification of a cytolethal distending toxin gene locus and features of a virulence-associated region in Actinobacillus actinomycetemcomitans. (1/397)
A genetic locus for a cytolethal distending toxin (CDT) was identified in a polymorphic region of the chromosome of Actinobacillus actinomycetemcomitans, a predominant oral pathogen. The locus was comprised of three open reading frames (ORFs) that had significant amino acid sequence similarity and more than 90% sequence identity to the cdtABC genes of some pathogenic Escherichia coli strains and Haemophilus ducreyi, respectively. Sonic extracts from recombinant E. coli, containing the A. actinomycetemcomitans ORFs, caused the distension and killing of Chinese hamster ovary cells characteristic of a CDT. Monoclonal antibodies made reactive with the CdtA, CdtB, and CdtC proteins of H. ducreyi recognized the corresponding gene products from the recombinant strain. CDT-like activities were no longer expressed by the recombinant strain when an OmegaKan-2 interposon was inserted into the cdtA and cdtB genes. Expression of the CDT-like activities in A. actinomycetemcomitans was strain specific. Naturally occurring expression-negative strains had large deletions within the region of the cdt locus. The cdtABC genes were flanked by an ORF (virulence plasmid protein), a partial ORF (integrase), and DNA sequences (bacteriophage integration site) characteristic of virulence-associated regions. These results provide evidence for a functional CDT in a human oral pathogen. (+info)Actinobacillus actinomycetemcomitans immunosuppressive protein is a member of the family of cytolethal distending toxins capable of causing a G2 arrest in human T cells. (2/397)
We have previously shown that Actinobacillus actinomycetecomitans produces an immunosuppressive factor (ISF) capable of impairing human lymphocyte function by perturbing cell cycle progression. We now report that ISF is the product of the cdtB gene, one of three genes encoding the family of cytolethal distending toxins (Cdt). The ISF polypeptide exhibits >/=95% identity with Hemophilus ducreyi CdtB protein and +info)Identification and molecular analysis of rough-colony-specific outer membrane proteins of Actinobacillus actinomycetemcomitans. (3/397)
Actinobacillus actinomycetemcomitans, a gram-negative bacterium isolated from the human mouth, has been implicated in the pathogenesis of early-onset periodontitis. Primary isolates cultured from subgingival plaque exhibit an adherent, rough colony phenotype which spontaneously converts to a nonadherent, smooth phenotype upon in vitro subculture. The rough colony variant produces abundant fimbriae and autoaggregates, while the smooth colony variant is planktonic and produces scant fimbriae. To begin to understand the significance of colony variation in biofilm formation by A. actinomycetemcomitans, outer membrane protein profiles of four isogenic rough and smooth colony variants were compared by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Two proteins with relative molecular masses of 43 and 20 kDa were expressed by the rough colony variants exclusively. Expression of these proteins was not found to be dependent on growth phase, oxygen tension, or type of complex medium. N-terminal amino acid sequences of these proteins obtained by Edman degradation were compared with sequences from the University of Oklahoma A. actinomycetemcomitans genome database. Two contiguous open reading frames (ORFs) encoding proteins having sequence homology with these proteins were identified. The 43-kDa protein (RcpA [rough colony protein A]) was similar to precursor protein D of the general secretion pathway of gram-negative bacilli, while the 20-kDa protein (RcpB [rough colony protein B]) appeared to be unique. The genes encoding these proteins have been cloned from A. actinomycetemcomitans 283 and sequenced. A BLASTX (gapped BLAST) search of the surrounding ORFs revealed homology with other fimbria-related proteins. These data suggest that the genes encoding the 43-kDa (rcpA) and 20-kDa (rcpB) proteins may be functionally related to each other and to genes that may encode fimbria-associated proteins. (+info)A novel NDP-6-deoxyhexosyl-4-ulose reductase in the pathway for the synthesis of thymidine diphosphate-D-fucose. (4/397)
The serotype-specific polysaccharide antigen of Actinobacillus actinomycetemcomitans Y4 (serotype b) consists of D-fucose and L-rhamnose. Thymidine diphosphate (dTDP)-D-fucose is the activated nucleotide sugar form of D-fucose, which has been identified as a constituent of structural polysaccharides in only a few bacteria. In this paper, we show that three dTDP-D-fucose synthetic enzymes are encoded by genes in the gene cluster responsible for the synthesis of serotype b-specific polysaccharide in A. actinomycetemcomitans. The first and second steps of the dTDP-D-fucose synthetic pathway are catalyzed by D-glucose-1-phosphate thymidylyltransferase and dTDP-D-glucose 4,6-dehydratase, which are encoded by rmlA and rmlB in the gene cluster, respectively. These two reactions are common to the well studied dTDP-L-rhamnose synthetic pathway. However, the enzyme catalyzing the last step of the dTDP-D-fucose synthetic pathway has never been reported. We identified the fcd gene encoding a dTDP-4-keto-6-deoxy-D-glucose reductase. After purifying the three enzymes, their enzymatic activities were analyzed by reversed-phase high performance liquid chromatography. In addition, nuclear magnetic resonance analysis and gas-liquid chromatography analysis proved that the fcd gene product converts dTDP-4-keto-6-deoxy-D-glucose to dTDP-D-fucose. Moreover, kinetic analysis of the enzyme indicated that the Km values for dTDP-4-keto-6-deoxy-D-glucose and NADPH are 97.3 and 28.7 microM, respectively, and that the enzyme follows the sequential mechanism. This paper is the first report on the dTDP-D-fucose synthetic pathway and dTDP-4-keto-6-deoxy-D-glucose reductase. (+info)Improved multiplex PCR using conserved and species-specific 16S rRNA gene primers for simultaneous detection of Actinobacillus actinomycetemcomitans, Bacteroides forsythus, and Porphyromonas gingivalis. (5/397)
Among putative periodontal pathogens, Actinobacillus actinomycetemcomitans, Bacteroides forsythus, and Porphyromonas gingivalis are most convincingly implicated as etiological agents in periodontitis. Therefore, techniques for detection of those three species would be of value. We previously published a description of a multiplex PCR that detects A. actinomycetemcomitans and P. gingivalis. The present paper presents an improvement on that technique, which now allows more sensitive detection of all three periodontal pathogens. Sensitivity was determined by testing serial dilutions of A. actinomycetemcomitans, B. forsythus, and P. gingivalis cells. Primer specificity was tested against (i) all gene sequences from the GenBank-EMBL database, (ii) six A. actinomycetemcomitans, one B. forsythus, and four P. gingivalis strains, (iii) eight different species of oral bacteria, and (iv) supra- and subgingival plaque samples from 20 healthy subjects and subgingival plaque samples from 10 patients with periodontitis. The multiplex PCR had a detection limit of 10 A. actinomycetemcomitans, 10 P. gingivalis, and 100 B. forsythus cells. Specificity was confirmed by the fact that (i) none of our forward primers were homologous to the 16S rRNA genes of other oral species, (ii) amplicons of predicted size were detected for all A. actinomycetemcomitans, B. forsythus, and P. gingivalis strains tested, and (iii) no amplicons were detected for the eight other bacterial species. A. actinomycetemcomitans, B. forsythus, and P. gingivalis were detected in 6 of 20, 1 of 20, and 11 of 20 of supragingival plaque samples, respectively, and 4 of 20, 7 of 20, and 13 of 20 of subgingival plaque samples, respectively, from periodontally healthy subjects. Among patients with periodontitis, the organisms were detected in 7 of 10, 10 of 10, and 7 of 10 samples, respectively. The simultaneous detection of three periodontal pathogens is an advantage of this technique over conventional PCR assays. (+info)Identification of genes coding for exported proteins of Actinobacillus actinomycetemcomitans. (6/397)
Random fusions of genomic DNA fragments to a partial gene encoding a signal sequence-deficient bacterial alkaline phosphatase were utilized to screen for exported proteins of Actinobacillus actinomycetemcomitans in Escherichia coli. Twenty-four PhoA(+) clones were isolated and sequenced. Membrane localization signals in the form of signal sequences were deduced from most of these sequences. Several of the deduced amino acid sequences were found to be homologous to known exported or membrane-associated proteins. The complete genes corresponding to two of these sequences were isolated from an A. actinomycetemcomitans lambda phage library. One gene was found to be homologous to the outer membrane lipoprotein LolB. The second gene product had homology with a Haemophilus influenzae protein and was localized to the inner membrane of A. actinomycetemcomitans. (+info)Microtubules are associated with intracellular movement and spread of the periodontopathogen Actinobacillus actinomycetemcomitans. (7/397)
Actinobacillus actinomycetemcomitans SUNY 465, the invasion prototype strain, enters epithelial cells by an actin-dependent mechanism, escapes from the host cell vacuole, and spreads intracellularly and to adjacent epithelial cells via intercellular protrusions. Internalized organisms also egress from host cells into the assay medium via protrusions that are associated with just a single epithelial cell. Here we demonstrate that agents which inhibit microtubule polymerization (e.g., colchicine) and those which stabilize polymerized microtubules (e.g., taxol) both increase markedly the number of intracellular A. actinomycetemcomitans organisms. Furthermore, both colchicine and taxol prevented the egression of A. actinomycetemcomitans from host cells into the assay medium. Immunofluorescence microscopy revealed that protrusions that mediate the bacterial spread contain microtubules. A. actinomycetemcomitans SUNY 465 and 652, strains that are both invasive and egressive, interacted specifically with the plus ends (growing ends) of the filaments of microtubule asters in a KB cell extract. By contrast, neither A. actinomycetemcomitans 523, a strain that is invasive but not egressive, nor Haemophilus aphrophilus, a noninvasive oral bacterium with characteristics similar to those of A. actinomycetemcomitans, bound to microtubules. Together these data suggest that microtubules function in the spread and movement of A. actinomycetemcomitans and provide the first evidence that host cell dispersion of an invasive bacterium may involve the usurption of host cell microtubules. (+info)Direct selection of IS903 transposon insertions by use of a broad-host-range vector: isolation of catalase-deficient mutants of Actinobacillus actinomycetemcomitans. (8/397)
Transposon mutagenesis in bacteria generally requires efficient delivery of a transposon suicide vector to allow the selection of relatively infrequent transposition events. We have developed an IS903-based transposon mutagenesis system for diverse gram-negative bacteria that is not limited by transfer efficiency. The transposon, IS903phikan, carries a cryptic kan gene, which can be expressed only after successful transposition. This allows the stable introduction of the transposon delivery vector into the host. Generation of insertion mutants is then limited only by the frequency of transposition. IS903phikan was placed on an IncQ plasmid vector with the transposase gene located outside the transposon and expressed from isopropyl-beta-D-thiogalactopyranoside (IPTG)-inducible promoters. After transposase induction, IS903phikan insertion mutants were readily selected in Escherichia coli by their resistance to kanamycin. We used IS903phikan to isolate three catalase-deficient mutants of the periodontal pathogen Actinobacillus actinomycetemcomitans from a library of random insertions. The mutants display increased sensitivity to hydrogen peroxide, and all have IS903phikan insertions within an open reading frame whose predicted product is closely related to other bacterial catalases. Nucleotide sequence analysis of the catalase gene (designated katA) and flanking intergenic regions also revealed several occurrences of an 11-bp sequence that is closely related to the core DNA uptake signal sequence for natural transformation of Haemophilus influenzae. Our results demonstrate the utility of the IS903phikan mutagenesis system for the study of A. actinomycetemcomitans. Because IS903phikan is carried on a mobilizable, broad-host-range IncQ plasmid, this system is potentially useful in a variety of bacterial species. (+info)
