Interaction of inflammatory cells and oral microorganisms. III. Modulation of rabbit polymorphonuclear leukocyte hydrolase release response to Actinomyces viscosus and Streptococcus mutans by immunoglobulins and complement. (1/562)

In the absence of antiserum, rabbit polymorphonuclear leukocytes (PMNs) released lysosomal enzymes in response to Actinomyces viscosus (19246) but not to Streptococcus mutans (6715). Antibodies had a marked modulating influence on these reactions. PMN hydrolase release was significantly enhanced to both organisms when specific rabbit antiserum and isolated immunoglobulin G (IgG) were included in the incubations. Immune complex F(ab')2 fragments of IgG directed against S. mutans agglutinated bacteria. Immune complexes consisting of S. mutans and F(ab')2 fragments of IgG directed against this organism were not effective as bacteria-IgG complexes in stimulating PMN release. The intensity of the release response to bacteria-IgG complexes was also diminished when PMNs were preincubated with isolated Fc fragments derived from IgG. Fresh serum as a source of complement components had no demonstrable effect on PMN release either alone or in conjuction with antiserum in these experiments. These data may be relevant to the mechanisms and consequences of the interaction of PMNs and plaque bacteria in the pathogenesis of periodontal disease.  (+info)

Pathogenesis of cancrum oris (noma): confounding interactions of malnutrition with infection. (2/562)

This study showed that impoverished Nigerian children at risk for cancrum oris (noma) had significantly reduced plasma concentrations of zinc (< 10.8 micromol/L), retinol (< 1.05 micromol/L), ascorbate (< 11 micromol/L), and the essential amino acids, with prominently increased plasma and saliva levels of free cortisol, compared with their healthy counterparts. The nutrient deficiencies, in concert with previously reported widespread viral infections (measles, herpesviruses) in the children, would impair oral mucosal immunity. We postulate, subject to additional studies, that evolution of the oral mucosal ulcers including acute necrotizing gingivitis to noma is triggered by a consortium of microorganisms of which Fusobacterium necrophorum is a key component. Fusobacterium necrophorum elaborates several dermonecrotic toxic metabolites and is acquired by the impoverished children via fecal contamination resulting from shared residential facilities with animals and very poor environmental sanitation.  (+info)

An Arcanobacterium (Actinomyces) pyogenes mutant deficient in production of the pore-forming cytolysin pyolysin has reduced virulence. (3/562)

Pyolysin (PLO), the hemolytic exotoxin expressed by Arcanobacterium (Actinomyces) pyogenes, is a member of the thiol-activated cytolysin family of bacterial toxins. Insertional inactivation of the plo gene results in loss of expression of PLO with a concomitant loss in hemolytic activity. The plo mutant, PLO-1, has an approximately 1. 8-log10 reduction in the 50% infectious dose compared to that for wild-type A. pyogenes in a mouse intraperitoneal infection model. Studies involving cochallenge of wild-type and PLO-1 bacteria resulted in recovery of similar numbers of both strains, suggesting that PLO production is required for survival in vivo. Recombinant, His-tagged PLO (His-PLO) is cytotoxic for mouse peritoneal macrophages and J774 cells in a dose-dependent manner. Protection against challenge with A. pyogenes could be afforded by vaccination with formalin-inactivated His-PLO, suggesting that PLO is a host-protective antigen, as well as a virulence determinant.  (+info)

Childhood actinomycosis. Report of 3 recent cases. (4/562)

Three cases of childhood actinomycosis are reported, 2 with the commonest presentation of cervicofacial abscess and the third with a rarely reported superficial chest wall abscess. The importance of prompt bacteriological diagnosis and adequate treatment with surgical drainage and chemotherapy is stressed. Though in adults males are affected more frequently than females, the sexes are probably equally affected in childhood.  (+info)

Strains of Actinomyces naeslundii and Actinomyces viscosus exhibit structurally variant fimbrial subunit proteins and bind to different peptide motifs in salivary proteins. (5/562)

Oral strains of Actinomyces spp. express type 1 fimbriae, which are composed of major FimP subunits, and bind preferentially to salivary acidic proline-rich proteins (APRPs) or to statherin. We have mapped genetic differences in the fimP subunit genes and the peptide recognition motifs within the host proteins associated with these differential binding specificities. The fimP genes were amplified by PCR from Actinomyces viscosus ATCC 19246, with preferential binding to statherin, and from Actinomyces naeslundii LY7, P-1-K, and B-1-K, with preferential binding to APRPs. The fimP gene from the statherin-binding strain 19246 is novel and has about 80% nucleotide and amino acid sequence identity to the highly conserved fimP genes of the APRP-binding strains (about 98 to 99% sequence identity). The novel FimP protein contains an amino-terminal signal peptide, randomly distributed single-amino-acid substitutions, and structurally different segments and ends with a cell wall-anchoring and a membrane-spanning region. When agarose beads with CNBr-linked host determinant-specific decapeptides were used, A. viscosus 19246 bound to the Thr42Phe43 terminus of statherin and A. naeslundii LY7 bound to the Pro149Gln150 termini of APRPs. Furthermore, while the APRP-binding A. naeslundii strains originate from the human mouth, A. viscosus strains isolated from the oral cavity of rat and hamster hosts showed preferential binding to statherin and contained the novel fimP gene. Thus, A. viscosus and A. naeslundii display structurally variant fimP genes whose protein products are likely to interact with different peptide motifs and to determine animal host tropism.  (+info)

Blastogenic response of human lymphocytes to oral bacterial antigens: comparison of individuals with periodontal disease to normal and edentulous subjects. (6/562)

Cell-mediated immunity in humans to antigens derived from oral plaque bacteria was investigated by using the lymphocyte blastogenesis assay. Subjects with varying severities of periodontal disease including normal, gingivitis, periodontitis, and edentulous were compared. Mononuclear leukocytes were separated from peripheral blood and cultured with antigens prepared by sonication of Actinomyces viscosus (AV), Actinomyces naeslundii (AN), Veillonella alcalescens (VA), Leptotrichia buccalis (LB), Bacteroides melaninogenicus (BM), and homologous dental plaque (DP). The lymphocyte response of subjects with gingivitis or periodontitis was significantly greater than that of normal subjects to antigens of AV, AN, and DP, but did not differ from the response of edentulous subjects. Periodontitis subjects were significantly more reactive than edentulous and normal subjects in response to VA, LB, and BM. These findings suggest that the tested gram-negative bacteria and the host response they evoke are associated with advanced periodontal destruction.  (+info)

Cell wall-anchored CshA polypeptide (259 kilodaltons) in Streptococcus gordonii forms surface fibrils that confer hydrophobic and adhesive properties. (7/562)

It has been shown previously that inactivation of the cshA gene, encoding a major cell surface polypeptide (259 kDa) in the oral bacterium Streptococcus gordonii, generates mutants that are markedly reduced in hydrophobicity, deficient in binding to oral Actinomyces species and to human fibronectin, and unable to colonize the oral cavities of mice. We now show further that surface fibrils 60.7 +/- 14.5 nm long, which are present on wild-type S. gordonii DL1 (Challis) cells, bind CshA-specific antibodies and are absent from the cell surfaces of cshA mutants. To more precisely determine the structural and functional properties of CshA, already inferred from insertional-mutagenesis experiments, we have cloned the entire cshA gene into the replicative plasmid pAM401 and expressed full-length CshA polypeptide on the cell surface of heterologous Enterococcus faecalis JH2-2. Enterococci expressing CshA exhibited a 30-fold increase in cell surface hydrophobicity over E. faecalis JH2-2 carrying the pAM401 vector alone and 2.4-fold-increased adhesion to human fibronectin. CshA expression in E. faecalis also promoted cell-cell aggregation and increased the ability of enterococci to bind Actinomyces naeslundii cells. Electron micrographs of negatively stained E. faecalis cells expressing CshA showed peritrichous surface fibrils 70.3 +/- 9.1 nm long that were absent from control E. faecalis JH2-2(pAM401) cells. The fibrils bound CshA-specific antibodies, as detected by immunoelectron microscopy, and the antibodies inhibited the adhesion of E. faecalis cells to fibronectin. The results demonstrate that the CshA polypeptide is the structural and functional component of S. gordonii adhesive fibrils, and they provide a molecular basis for past correlations of surface fibril production, cell surface hydrophobicity, and adhesion in species of oral "sanguis-like" streptococci.  (+info)

Bacterial flora of liver abscesses in feedlot cattle fed tylosin or no tylosin. (8/562)

Bacterial flora of liver abscesses from cattle fed tylosin or no tylosin and susceptibilities of the predominant bacterial isolates to tylosin and other antimicrobial compounds were determined. Abscessed livers were collected at slaughter from cattle originating from feedlots that had fed tylosin (n = 36) or no tylosin (n = 41) for at least 2 yr, and segments of livers with one or two intact abscesses were transported to the laboratory. Abscesses were cultured for anaerobic and facultative bacteria. Fusobacterium necrophorum, either as single culture or mixed with other bacteria, was isolated from all abscesses. The incidence of subsp. necrophorum, as part of the mixed infection, was lower (P < .05) in the tylosin group than in the no-tylosin group (33 vs 61%). However, the incidence of Actinomyces pyogenes was higher (P < .01) in the tylosin group than in the no-tylosin group (53 vs 10%). Totals of 119 F. necrophorum and 21 A. pyogenes isolates were used for determinations of susceptibilities to bacitracin, oxytetracycline, chlortetracycline, lasalocid, monensin, tylosin, tilmicosin, and virginiamycin. The minimum inhibitory concentrations (MIC) of antibiotics were determined with a broth microdilution method. The mean MIC of tylosin for F. necrophorum and A. pyogenes were not different between isolates from tylosin and no-tylosin groups. We concluded that continuous feeding of tylosin did not induce resistance in F. necrophorum or A. pyogenes. Also, the higher incidence of mixed infection of F. necrophorum and A. pyogenes in liver abscesses of tylosin-fed cattle suggests a potential synergistic interaction between the two organisms in causing liver abscesses.  (+info)

Gradual increasing of glycerol concentration up to 10% using sheep ruminal fluid as an inoculum for in vitro cultivation was accompanied by significant changes in bacterial population as documented by DGGE analysis. The resulting bacterial consortium was composed of three dominant bacteria with Actinomyces related bacterium to be predominant. Upon cultivation on media with glycerol as a sole carbon source a single bacterium was cultivated from this consortium. Isolate G10 was found to be anaerobic, Gram-positive rod-shaped bacterium. Phylogenetic analysis based on 16S rRNA gene sequences showed that G10 isolate is related to the Actinomyces ruminicola species (97.7% of similarity). The role of rumen actinobacteria is largely unknown and their participation in glycerol utilization (tolerance) has not been described yet. The G10 bacterium and related consortium could be possibly used to improve glycerol tolerance and uptake by ruminants ...
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.

Surely everyone knows that the first step in preventing tooth decay is their regular cleaning, however, it is very useful to know exactly how certain foods allow maintenance of tooth enamel and removing unsightly stains. Certain foods are bad for your body, especially your teeth. If you do not control the amount you eat, it can lead to serious problems.. Hard candy can stick to the surface of the tooth and requires a long time to decompose, so they are very harmful to the teeth. Some of them are so hard that they can cause your teeth to break if you bite into them. However, its not just about the amount of sugar you eat but how often, too.. Bacteria in the mouth love sugar, and the fermentation of sweet things into acid that eats away at the enamel of the tooth causes bleeding and formation of unsightly stains..

The widely conserved LytR-CpsA-Psr (LCP) family of enzymes in Gram-positive bacteria is known to attach glycopolymers, including wall teichoic acid, to the cell envelope. However, it is undetermined if these enzymes are capable of catalyzing glycan attachment to surface proteins. In the actinobacterium Actinomyces oris, an LCP homolog here named LcpA is genetically linked to GspA, a glycoprotein that is covalently attached to the bacterial peptidoglycan by the housekeeping sortase SrtA. Here we show by X-ray crystallography that LcpA adopts an α-β-α structural fold, akin to the conserved LCP domain, which harbors characteristic catalytic arginine residues. Consistently, alanine substitution for these residues, R149 and R266, abrogates GspA glycosylation, leading to accumulation of an intermediate form termed GspALMM, which is also observed in the lcpA mutant. Unlike other LCP proteins characterized to date, LcpA contains a stabilizing disulfide bond, mutations of which severely affect LcpA ...

Bacteria were isolated from the dental plaques of nine dogs and a sample of pooled saliva from five other dogs and were then identified by comparative 16S rRNA gene sequencing. Among 339 isolates, 84 different phylotypes belonging to 37 genera were identified. Approximately half of the phylotypes were identified to the species level, and 28% of these were considered members of the indigenous oral microbiota of humans. The 16S rRNA gene sequences of the remaining 44 phylotypes were not represented in GenBank, and most of these phylotypes were tentatively identified as candidate new species. The genera most frequently isolated from saliva were Actinomyces (26%), Streptococcus (18%), and Granulicatella (17%). The genera most frequently isolated from plaque were Porphyromonas (20%), Actinomyces (12%), and Neisseria (10%). A comparison of the DNA sequences from this study with sequences of the human microbiota available in GenBank showed that, on average, canine and human microbiotas differed by ...

Hi all: Im looking for a restriction enzyme that cuts human (eukaryotic) genomic DNA into smaller pieces than it does with bacterial (gram + actinomyces, GC-rich) chromosomal DNA. The purpose is to generate a bacterial chromosomal library from intracellularly grown bacteria (grown inside human macrophages) and to get rid of the human genomic DNA that may contaminate the bacterial DNA. If the human DNApieces are considerably smaller (lets say, below 10-15kb) than the bacterial ones (,25kb) the packaging of cosmids (Stratagene SuperCos) should exclude any DNA below 20kb (so they promise...).

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 ...
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.

From 10(9) to 10(10) washed organisms were introduced into the uterine lumen of four pregnant cows. Two pregnant cows were inoculated with sterile saline and four pregnant cows were treated with cloprostenol. Embryonic death and abortion followed 29 to 144 hours after the inoculation of the live bacteria. The aborted embryos were macerated or clearly degenerating and yielded profuse pure cultures of A pyogenes. Abortion was accompanied by a sustained increase in uterine tone, opening of the cervix, presence of vaginal pus and a vulval discharge and the persistence of the corpus luteum for at least eight days after abortion. Intrauterine inoculation with saline did not affect pregnancy, but embryonic death, abortion and regression of the corpus luteum occurred 66 to 72 hours after the treatment with cloprostenol. The results suggest that A pyogenes ...

Actinomycosis Definition Actinomycosis is an infection primarily caused by the bacterium Actinomyces israelii. Infection most often occurs in the face and neck region and is characterized by the presence of a slowly enlarging, hard, red lump.
The development of dental caries and periodontal diseases result from distinct shifts in the microbiota of the tooth-associated biofilm. This in vitro study aimed to investigate changes in biofilm composition and structure, during the shift from a supragingival aerobic profile to a subgingival anaerobic profile. Biofilms consisting of Actinomyces oris, Candida albicans, Fusobacterium nucleatum, Streptococcus oralis, Streptococcus mutans and Veillonella dispar were aerobically grown in saliva-containing medium on hydroxyapatite disks. After 64 h, Campylobacter rectus, Prevotella intermedia and Streptococcus anginosus were further added along with human serum, while culture conditions were shifted to microaerophilic. After 96 h, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola were finally added and the biofilm was grown anaerobically for another 64 h. At the end of each phase, biofilms were harvested for species-specific quantification and localization. Apart from C. ...
Actinomyces are gram-positive aerobic-growing bacteria that are part of human bacterial flora. They usually occur in a commensal relationship with the host, growing, in particular, on teeth and other surfaces in the mouth. Actinomyces infections, which are more prevalent among men than among women (3:1), usually affect patients in their fourth decade and most often involve A. israeli (85%). A. meyeri is less common. Actinomycosis occurs most frequently with cervicofacial involvement (in up to 65% of cases); thoracic, abdominal or pelvic actinomycosis is uncommon. Pulmonary infections and hematogeneous spread result more often from A. meyeri than from other actinomycetal species.1 Dentogingival disease is a risk factor for acquiring A. meyeri infection, and alcoholics are at high risk for pulmonary actinomycosis because of their poor dental health and the higher likelihood of aspiration of oral secretions.. Actinomycosis has a slowly progressive course and, sometimes, a history of preceding ...
Pathogenicity - causes the disease actinomycosis. In man it is usually caused by A. israelli. They are commensals of mouth, therefore endogenous cause of disease. The disease is a chronic granulomatous infection occuring in human beings and animals. It is characterized by the development of indurated swellings, in the connective tissue, suppuration and the discharge of sulfur granules. Actinomycosis in human beings is an endogenous infection. The actinomyces species are normally present in the mouth, intestine, vagina as commensals. Actinomycosis in human beings occurs in 4 forms : (a) Cervicofacial - indurated lesions on the cheek and submaxillary regions. (b) Thoracic - lesions in the lung involving pleura and pericardium and spread outwards through the chest wall. (c) Abdominal - lesion around the cecum, neighbouring tissues and the abdominal wall, sometimes spread to the liver. (d) Pelvic - lesion on the pelvic region, associated with the use of intrauterine devices. ...

Cephalexin is attributed as antibiotic of cephalosporins group which acts against bacteria preventing formation of their cell walls. It is enough resistant to penicillinases of gram positive microorganisms but can be destroyed by beta-lactamases of gram negative ones. It shows broad spectrum activity against gram positive microorganisms such as Staphylococcus, Staphylococcus epidermidis; Streptococcus, Corynebacterium diphtheriae, Clostridium, Actinomyces israelii, Bacillus anthracis, gram negative microorganisms like Escherichia coli, Klebsiella, Proteus mirabilis, Neisseria gonorrhoeae, Neisseria meningitidis, Shigella, Salmonella. Common infections that are treated with Cephalexin include infections of the middle ear, tonsils, throat, larynx (laryngitis), bronchi (bronchitis) and pneumonia as well as in urinary tract, skin, and bones ...
Pathophysiology of canaliculitis. As has been mentioned above, canaliculitis occurs due to infection of the canaliculi. This infection is often brought on by bacteria though there could be alternative aetiology such as fungi and viruses as well. The most common cause of canaliculitis is Actinomyces Israelii. However, the other causes can include aspergillus, Canada albicans and even herpes simplex and herpes zoster virus.. Infection by these organisms results in the formation of tiny stones that are rich in sulphur. These stones form little pockets that unfortunately are not affected by the antimicrobial properties of tears.. History and examination. ...

The most common physical finding of actinomycosis is a woody, hard, palpable mass with a subacute clinical course. About half of the patients present with a low-grade fever (1). The lack of responsiveness to empirical antibiotic therapy, the presentation of a chronic palpable mass, and the difficulty in establishing the microbiologic diagnosis make it difficult to differentiate this mass from a neoplasm, granulomatous disease, or a fungal infection on the basis of the initial presentation (1, 4).. Actinomyces species are anaerobic bacteria that cannot penetrate healthy tissue, and mucosal breakdown is a prerequisite for infection. About half of the patients have a history of local trauma resulting in mucosal breakdown (1). Poor dental hygiene, caries, oral trauma, dental extraction, and an immunocompromised status are considered to be important antecedents (1, 4). Determining if a patient has a history of these risk factors may be helpful in establishing a correct diagnosis. In cervicofacial ...
BACKGROUND The purpose of this in-vitro study was to investigate the potential of biofilm removal in interproximal tooth regions using intervallic cleaning with an oral irrigator or a sonic toothbrush. METHODS Three-species biofilms (Streptococcus mutans (OMZ 918), Streptococcus oralis SK 248 (OMZ 60), Actinomyces naeslundii (OMZ 745)) were grown on hydroxyapatite discs for 3 days in culture media. Every 24 h, specimens were incubated for 15 min in resazurin solution (i.e., culture medium and 10 % v/v alamarBlue®) to measure the metabolic activity with a fluorescence spectrophotometer in relative fluorescence units (rfu) at baseline. Then, specimens were fixed in interproximal holding devices and underwent treatment with an oral irrigator (WF; Waterpik® Sensonic WP-100E), an active sonic toothbrush (WPa), or an inactive sonic toothbrush (WPi; Waterpik® Sensonic SR-3000E) for 10 s (n = 18/group). Untreated biofilms served as controls (CO). After treatment, bacterial activity was re-measured, ...
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 ...

Contributor Comment: Actinomycosis is a pyogranulomatous osteomyelitis that primarily affects cattle and is caused by the gram-positive bacterium Actinomyces bovis.9 Occasionally other species such as pigs, deer, sheep, goats and horses are affected.9 A similar species of bacterium, A. israeli, is responsible for the disease in human beings.6 The affected bone is thickened from multiple coalescing py-ogranulomas that impart to the bone tissue a honeycomb appearance.5 The inoculation of A. bovis - a commensal organism of the oral cavity - into the oral mucosa of animals can be facilitated by small wounds from hard straw present in the feed, foreign bodies and dental eruption. 9. Although actinomycosis has been described in cattle at unusual sites such as the penis and in the maxilla, as in the case presented here, the classical presentation in cattle is in the mandible and rarely in the maxilla.9,12 It is likely that the reason the mandible is the preferred site is because the direction of ...
