Addition of antibacterial agents to MMA-TBB dentin bonding systems--influence on tensile bond strength and antibacterial effect. (1/19)

To produce a bonding system which has both high bond strength and antibacterial properties, an antibacterial agent (vancomycin: VCM or metronidazol: MN) was added to the PMMA powder of 4-META/MMA-TBB resin (CB). The influence of the addition of an antibacterial agent on tensile bond strength to dentin and the antibacterial effect were investigated in this study. Forty-seven freshly extracted bovine first or second incisors were used to measure the tensile bond strength to dentin. The bond strengths to bovine dentin were not significantly decreased by addition of VCM (1%, 2%, 5%), or MN (1%) to CB (p < 0.05). The antibacterial effect of CB containing antibacterial agent on six strains of bacteria was investigated by the agar plate diffusion method, analyzing the appearance of the inhibition zone around a resin disk following anaerobic culturing. The resin disks containing VCM showed antibacterial effects on all of the strains examined; the widths of the inhibition zones were 4-15 mm. The resin disks containing MN showed antibacterial effects on three strains; the widths of the inhibition zones were 0-4 mm. It was thus possible to produce a bonding system with both antibacterial effect and high tensile bond strength by addition of VCM to PMMA powder.  (+info)

Different type 1 fimbrial genes and tropisms of commensal and potentially pathogenic Actinomyces spp. with different salivary acidic proline-rich protein and statherin ligand specificities. (2/19)

Actinomyces spp. exhibit type 1 fimbria-mediated adhesion to salivary acidic proline-rich proteins (PRPs) and statherin ligands. Actinomyces spp. with different animal and tissue origins belong to three major adhesion types as relates to ligand specificity and type 1 fimbria genes. (i) In preferential acidic-PRP binding, strains of Actinomyces naeslundii genospecies 1 and 2 from human and monkey mouths displayed at least three ligand specificities characterized by preferential acidic-PRP binding. Slot blot DNA hybridization showed seven highly conserved type 1 fimbria genes (orf1- to -6 and fimP) in genospecies 1 and 2 strains, except that orf5 and orf3 were divergent in genospecies 1. (ii) In preferential statherin binding, oral Actinomyces viscosus strains of rat and hamster origin (and strain 19246 from a human case of actinomycosis) bound statherin preferentially. DNA hybridization and characterization of the type 1 fimbria genes from strain 19246 revealed a homologous gene cluster of four open reading frames (orfA to -C and fimP). Bioinformatics suggested sortase (orfB, orf4, and part of orf5), prepilin peptidase (orfC and orf6), fimbria subunit (fimP), and usher- and autotransporter-like (orfA and orf1 to -3) functions. Those gene regions corresponding to orf3 and orf5 were divergent, those corresponding to orf2, orf1, and fimP were moderately conserved, and those corresponding to orf4 and orf6 were highly conserved. Restriction fragment length polymorphism analyses using a fimP probe separated human and monkey and rat and hamster strains into phylogenetically different groups. (iii) In statherin-specific binding, strains of A. naeslundii genospecies 1 from septic and other human infections displayed a low-avidity binding to statherin. Only the orf4 and orf6 gene regions were highly conserved. Finally, rat saliva devoid of statherin bound bacterial strains avidly irrespective of ligand specificity, and specific antisera detected either type 1, type 2, or both types of fimbria on the investigated Actinomyces strains.  (+info)

Isolation and characterization of Actinomyces viscosus mutants defective in binding salivary proline-rich proteins. (3/19)

Recent studies have provided evidence for human salivary proline-rich proteins (PRPs) serving as potential receptors in the acquired pellicle for Actinomyces viscosus type 1 fimbriae. We report here the isolation of mutants derived from A. viscosus T14V-J1 which are defective in binding to PRPs partially purified from parotid gland saliva. Mutagenesis with ethyl methanesulfonate preceded enrichment for cells nonreactive with PRPs by successive adsorptions with PRP-treated latex beads. Screening was accomplished by random selection of 250 isolated colonies from each of four enrichment cycles and reaction with PRP-treated latex beads in microtiter plates. Two mutants of independent origin were examined for adherence to hydroxyapatite treated with either PRPs, proline-rich glycoproteins, deglycosylated proline-rich glycoproteins, or whole saliva. Additional surface properties that were examined included agglutination with polyclonal antisera to type 1 and type 2 fimbriae, agglutination by a monoclonal antibody to type 1 fimbriae that inhibits adherence of the parent strain to saliva-treated hydroxyapatite, the ability to bind monoclonal antibody to the type 1 fimbrial subunit, and lactose-reversible coaggregation with Streptococcus sanguis 34. Both mutants exhibited reduced binding to hydroxyapatite treated with whole saliva or salivary protein preparations but were still capable of reaction with antiserum to type 1 and type 2 fimbriae. In addition, these mutants possessed the ability to bind monoclonal antibody to the type 1 fimbrial subunit in amounts comparable to the amount bound by the parent strain but were not agglutinated by the adherence-inhibiting monoclonal antibody. When considered with previously published data, these results suggest that an adhesive molecule is probably associated with type 1 fimbriae and allows for the interaction of A. viscosus with constituents in the salivary pellicle.  (+info)

Effects of cecropin-XJ on growth and adherence of oral cariogenic bacteria in vitro. (4/19)

BACKGROUND: Cecropin-XJ belongs to cecropin-B, which is the most potent antibacterial peptide found naturally. The aim of this study was to investigate the effects of cecropin-XJ on growth and adherence of oral cariogenic bacteria. METHODS: Four oral cariogenic bacteria (Streptococcus mutans, Lactobacillus acidophilus, Actinomyces viscosus and Actinomyces naeslundii) were chosen for this experiment. The minimal inhibitory concentrations (MICs) and reductive percent of bacterial growth were used to assay the antibacterial activity of cecropin-XJ. Mammalian cytotoxicity of cecropin-XJ was tested with human periodontal membrane fibroblasts by tetrazolium (MTT) colorimetric assay. The bacterial morphological changes induced by cecropin-XJ were examined on scanning electron microscope (SEM). The influence of cecropin-XJ on bacterial adhesion to saliva-coated hydroxyapatite (S-HA) was measured by scintillation counting. RESULTS: The MICs of cecropin-XJ for inhibition of the growth of four bacteria ranged from 4.0 to 42.8 micromol/L with the highest susceptible to A. naeslundii and the lowest susceptible to L. acidophilus. At pH 6.8, 5.5 and 8.2, 1/2 MIC of cecropin-XJ reduced the number of viable bacteria by 40.9%, 67.8% and 32.8% for S. mutans and by 28.1%, 57.2% and 37.9% for L. acidophilus. The activities against S. mutans and L. acidophilus increased at pH 5.5 compared with pH 6.8 (P < 0.01, respectively). In present of 50% saliva, 1/2 MIC of the peptide decreased the direct count of viable cells by 29.2% and 14.4% for S. mutans and L. acidophilus, respectively (P < 0.01 and P > 0.05, respectively), whereas almost no reduction counts were detected in the presence of 20% serum for both bacteria (P > 0.05, respectively). Mammalian cytotoxicity of cecropin-XJ from 1.0 to 100 micromol/L exhibited no cytotoxicity against human periodontal membrane fibroblasts (P > 0.05). Bacterial morphological changes induced by MIC of cecropin-XJ examined on SEM showed cell surface disruption. Furthermore, the ability of A. naeslundii adhesion to S-HA decreased significantly with MIC of cecropin-XJ for 10 and 20 minutes (P = 0.001 and 0.000, respectively), and S. mutans, A. viscosus to S-HA decreased significantly with MIC of cecropin-XJ for 20 minutes (P = 0.000, respectively). CONCLUSIONS: Cecropin-XJ exhibited bactericidal action against cariogenic pathogens, and the antibacterial activity enhanced in the acid environment. The results also demonstrate that cecropin-XJ prevents S. mutans and actinomyces adsorption to S-HA. These findings suggest that Cecropin-XJ may have potential to prevent caries.  (+info)

Immunochemical and functional studies of Actinomyces viscosus T14V type 1 fimbriae with monoclonal and polyclonal antibodies directed against the fimbrial subunit. (5/19)

Each of five monoclonal antibodies (mAbs) prepared against the type 1 fimbriae of Actinomyces viscosus T14V reacted with a 54 kDa cloned protein previously identified as a fimbrial subunit. This purified protein completely inhibited the reaction of a specific anti-type-1-fimbria rabbit antibody with A. viscosus whole cells. Maximum values for the number of antibody molecules bound per bacterial cell ranged from 7 x 10(3) to 1.2 x 10(4) for the different 125I-labelled mAbs and was approximately 7 x 10(4) for 125I-labelled rabbit IgG or Fab against either type 1 fimbriae or the 54 kDa cloned protein. Although the different mAbs, either individually or as a mixture, failed to inhibit the type-1-fimbria-mediated adherence of A. viscosus T14V to saliva-treated hydroxyapatite, each rabbit antibody gave 50% inhibition of adherence when approximately 5 x 10(4) molecules of IgG were bound per cell. However, binding of each corresponding rabbit Fab had no significant effect on bacterial attachment unless much higher concentrations were used. These findings suggest that antibodies directed solely against the 54 kDa fimbrial subunit do not react with the putative receptor binding sites of A. viscosus T14V type 1 fimbriae. Instead, inhibition of attachment by the polyclonal antibodies may depend on an indirect effect of antibody binding that prevents the fimbria-receptor interaction.  (+info)

Tyrosine sulfation of statherin. (6/19)

Tyrosylprotein sulfotransferase (TPST), responsible for the sulfation of a variety of secretory and membrane proteins, has been identified and characterized in submandibular salivary glands (William et al. Arch Biochem Biophys 1997; 338: 90-96). In the present study we demonstrate the sulfation of a salivary secretory protein, statherin, by the tyrosylprotein sulfotransferase present in human saliva. Optimum statherin sulfation was observed at pH 6.5 and at 20 mm MnCl(2). Increase in the level of total sulfation was observed with increasing statherin concentration. The K(m)value of tyrosylprotein sulfotransferase for statherin was 40 microM. Analysis of the sulfated statherin product on SDS-polyacrylamide gel electrophoresis followed by autoradiography revealed (35)S-labelling of a 5 kDa statherin. Further analysis of the sulfated statherin revealed the sulfation on tyrosyl residue. This study is the first report demonstrating tyrosine sulfation of a salivary secretory protein. The implications of this sulfation of statherin in hydroxyapatite binding and Actinomyces viscosus interactions are discussed.  (+info)

Activity of an antimicrobial peptide mimetic against planktonic and biofilm cultures of oral pathogens. (7/19)

Antimicrobial peptides (AMPs) are naturally occurring, broad-spectrum antimicrobial agents that have recently been examined for their utility as therapeutic antibiotics. Unfortunately, they are expensive to produce and are often sensitive to protease digestion. To address this problem, we have examined the activity of a peptide mimetic whose design was based on the structure of magainin, exhibiting its amphiphilic structure. We demonstrate that this compound, meta-phenylene ethynylene (mPE), exhibits antimicrobial activity at nanomolar concentrations against a variety of bacterial and Candida species found in oral infections. Since Streptococcus mutans, an etiological agent of dental caries, colonizes the tooth surface and forms a biofilm, we quantified the activity of this compound against S. mutans growing under conditions that favor biofilm formation. Our results indicate that mPE can prevent the formation of a biofilm at nanomolar concentrations. Incubation with 5 nM mPE prevents further growth of the biofilm, and 100 nM mPE reduces viable bacteria in the biofilm by 3 logs. Structure-function analyses suggest that mPE inhibits the bioactivity of lipopolysaccharide and binds DNA at equimolar ratios, suggesting that it may act both as a membrane-active molecule, similar to magainin, and as an intracellular antibiotic, similar to other AMPs. We conclude that mPE and similar molecules display great potential for development as therapeutic antimicrobials.  (+info)

Isolation of a neuraminidase gene from Actinomyces viscosus T14V. (8/19)

A genomic library of Actinomyces viscosus T14V DNA in lambda gt11 was screened for expression of neuraminidase activities. Four recombinant clones were detected that gave blue fluorescence upon incubation with a fluorogenic substrate, 2'-(4-methylumbelliferyl)-alpha-D-N-acetylneuraminic acid. Of these, two were identical, and all of the neuraminidase-positive clones shared a common 3.4-kbp DNA region. Expression of the enzyme activities in Escherichia coli carrying the cloned DNA was independent of the lacZ promoter of the vector. Maxicell analysis revealed that the 3.4-kbp DNA insert directed synthesis of a protein with an apparent molecular mass of 100,000 Da. The protein from cell extracts of E. coli clones migrated as a single band that stained for enzyme activity after electrophoresis in a nondissociating polyacrylamide gel. Moreover, human erythrocytes incubated previously with cell lysates from neuraminidase-positive E. coli were hemagglutinated by Actinomyces spp. The enzyme expressed by E. coli was active on substrates containing alpha-2,3 and alpha-2,6 ketosidic linked sialyl residues. Similar substrate specificities were obtained for both the extracellular and cell-associated neuraminidases from A. viscosus T14V. The 3.4-kbp insert hybridized to DNA fragments in a Southern blot containing A. viscosus T14V chromosomal DNA that had been digested with various restriction endonucleases. Data from hybridization studies show that A. viscosus T14V contains a single copy of the neuraminidase gene.  (+info)

Rhizomes of Boesenbergia pandurata (Roxb.) Schlecht have been reported to contain active compounds with anticancer properties. This research was carried out to examine anti-proliferative and apoptotic induction against HeLa and Vero cells-line. Dried powder of B. pandurata rhizomes was extracted by a maceration method using 90% ethanol. Cytotoxic assays to determine IC50 and anti-proliferative effects were carried out by MTT methods. Observation of apoptosis was achieved with double staining using acridine orange and ethidium bromide. The results showed that ethanolic extract of B. pandurata was more cytotoxic against HeLa cells (IC50 of 60 μg/ mL) than Vero cells (IC50 of 125 μg/mL). The extract had higher anti-proliferative activity as well as apoptotic induction in HeLa than Vero cells. Therefore, it was concluded that the ethanolic extract of B. pandurata had anti-proliferative as well as apoptosis induction activity dependent on the cell type.

INTRODUCTION. Although many of the strains of Actinomyces are highly sensitive in vitro to many antimicrobial agents, the disease caused in human beings by these microörganisms continues to present difficult therapeutic problems. The distinctive character of the tissue reaction offers a logical explanation for some of these problems. The involved areas are usually extensive, markedly indurated, and relatively avascular in the region of the active growth of the Actinomyces. These features suggest serious difficulty in getting a bactericidal concentration of the effective drug into areas of active infection, and raise serious doubts concerning the possibility of restoring the involved tissues ...

Dental caries (tooth decay) is caused by a specific group of cariogenic bacteria, like Streptococcus mutans, which convert dietary sugars into acids that dissolve the mineral in tooth structure. Killing cariogenic bacteria is an effective way to control or prevent tooth decay. In a previous study, we discovered a novel compound (Glycyrrhizol A), from the extraction of licorice roots, with strong antimicrobial activity against cariogenic bacteria. In the current study, we developed a method to produce these specific herbal extracts in large quantities, and then used these extracts to develop a sugar‐free lollipop that effectively kills cariogenic bacteria like Streptococcus mutans. Further studies showed that these sugar‐free lollipops are safe and their antimicrobial activity is stable. Two pilot human studies indicate that a brief application of these lollipops (twice a day for ten days) led to a marked reduction of cariogenic bacteria in oral cavity among most human subjects tested.

TY - CHAP. T1 - Diseases caused by actinomyces species. AU - Booth, James. PY - 2007. Y1 - 2007. N2 - The genus Actinomyces consists of facultatively anaerobic and obligately anaerobic gram-positive filamentous rods that microscopically resemble the hyphae of the eukaryotic fungi. Actinomyces are true bacteria (prokaryotic). They should not be confused with the aerobic "actinomycetes", which includes Nocardia and related bacteria that they resemble microscopically. The most common infection due to Actinomyces is actinomycosis, although this term can be applied to similar infections caused by other species, such as Propionibacterium propionicum..

Biological action on cariogenic bacteria. The analysis of results shows that a different propolis sample does not have the same inhibitory activity on bacterial growth, but all of them inhibited the mutans streptococci growth. Also, we can see that this activity has a direct relation with the concentration of polyphenols, as determined by the Folin-Ciocalteau method (Table 2). The EEP P001 and P008 from central Chile showed the lowest antimicrobial activity (MIC 6.67 and 8.22, respectively). Similarly, highlighting the propolis P019 and P020, from southern Chile showed the highest antimicrobial activity (MIC 1.94 and 0.90, respectively). When comparing the MIC for S. mutans and S. sobrinus according to the sample origin we observed for both of them that MIC was lowest with southern propolis (p = 0.011 and p = 0.007, respectively). In addition, the statistical analyses showed that propolis from southern Chile (P013 to P020) have the highest polyphenols contents when compared with other regions of ...
The best antimicrobial activity has been displayed by the LMM mushroom extract with a bacteriostatic effect. At the MIC of both extracts DNA synthesis was the main macromolecular synthesis inhibited, RNA synthesis was less inhibited than that of DNA and protein synthesis was inhibited only by roughly 50%. The partial inhibition of protein synthesis is compatible with the observed significant increase in cell mass. The increase in these parameters is linked to the morphological alteration with transition from cocci of the untreated control to elongated cells. Interestingly, these modifications were also observed at sub-MIC concentrations. Finally, membrane and cytosol proteome analysis was conducted under LMM mushroom extract treatment in comparison with untreated S. mutans cells. Significant changes were observed for 31 membrane proteins and 20 of the cytosol fractions. The possible role of the changed proteins is discussed ...

The aim of this paper was to elucidate the mechanisms behind salivary lubrication with special emphasis on the lubricity of three pellicle key components (human acidic proline-rich protein 1 (PRP-1), human statherin and bovine submaxillary mucin (BSM)). The lubricating properties of the proteins have been assessed by means of colloidal probe atomic force microscopy, and are discussed in relation to their adsorption behavior. To various extent, the investigated proteins all showed a lubricating effect when adsorbed to silica surfaces. For comparable concentrations, PRP-1 was found to have a more pronounced lubricating effect than BSM, which in turn showed a higher lubricity than statherin. The relative lubricity is in accordance with previously reported relative adsorbed amounts of the three proteins, within the investigated concentration interval. We conclude that PRP-1 has the highest lubricating capacity as a pure fraction among the investigated preparations, and that the lubricating effect of ...
Dental caries is the most prevalent disease in humans globally. Efforts to control it have been invigorated by an increasing knowledge of the oral microbiome composition. This study aimed to evaluate the bacterial diversity in occlusal biofilms and its relationship with clinical surface diagnosis and dietary habits. Anamneses were recorded from thirteen 12-year-old children. Biofilm samples collected from occlusal surfaces of 46 permanent second molars were analyzed by 16S rRNA amplicon sequencing combined with the BLASTN-based search algorithm for species identification. The overall mean decayed, missing and filled surfaces modified index [DMFSm Index, including active white spot lesions (AWSL)] value was 8.77±7.47. Biofilm communities were highly polymicrobial collectively, representing 10 bacterial phyla, 25 classes, 29 orders, 58 families, 107 genera, 723 species.

R. Patel1, S. Misra1, S. Joseph1 1Texas Tech University Health Sciences,Department Of Surgery,Odessa, TX, USA. Introduction: Acute appendicitis can present with a wide range of symptoms from an indolent course to severe peritonitis and overwhelming sepsis. The patients clinical status often indicates the severity of the disease and if perforation and diffuse peritonitis is present. While there have been many attempts to identify patients who may develop sepsis and peritonitis, little has been found as to the cause of the most severe cases.. Actinomyces, a gram positive facultative anaerobe, is part of the normal flora of the mouth, GI tract, and female vagina, however when pathologic it causes severe inflammation, gangrene, perforation, and obstruction. Actinomyces can easily be identified on pathologic examination by the formation of sulfur granules. We hypothesized that Actinomyces could be a causative agent in patients who present with perforated or gangrenous appendicitis.. Methods: We did a ...
Actinomycosis is a rare infectious bacterial disease caused by Actinomyces species. About 70% of infections are due to either Actinomyces israelii or A. gerencseriae. Infection can also be caused by other Actinomyces species, as well as Propionibacterium propionicus, which presents similar symptoms. The condition is likely to be polymicrobial aerobic anaerobic infection. The disease is characterised by the formation of painful abscesses in the mouth, lungs, breast, or gastrointestinal tract. Actinomycosis abscesses grow larger as the disease progresses, often over months. In severe cases, they may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus, which often contains characteristic granules (sulfur granules) filled with progeny bacteria. These granules are named due to their appearance, but are not actually composed of sulfur. Actinomycosis is primarily caused by any of several members of the bacterial genus Actinomyces. These bacteria ...
