Abstract:

Background: Periodontal disease has been reported to play a causative role in acute myocardial infarction (AMI), which may add to the various risk factors associated with coronary heart disease. The objective of the present study was to investigate the presence of Prevotella intermedia – an established periodontal pathogen – in subgingival plaque samples of chronic periodontitis and AMI patients in order to identify a possible association, and to evaluate the susceptibility of Prevotella intermedia to nine antimicrobial agents. Methods: After undergoing screening for eligibility, a total of 50 subjects were included in the present study. Twenty patients were diagnosed with AMI and generalized chronic periodontitis (Group I), 20 patients were diagnosed with only AMI (Group II), and 10 subjects were healthy controls (Group III). The isolated Prevotella intermedia strains were tested for susceptibility to bacitracin, chloramphenicol, penicillin G, polymyxin, gentamycin, neomycin, tetracycline, cefotaxime, and cefoxitin using an antibiotic zonescale to determine minimum inhibitory concentrations (MICs). Results: Periodontal pathogens were identified by phenotypic and enzymatic methods. The mean bacterial load of Prevotella intermedia species was higher in Group I compared to Group II and Group III. It was also found that pencillin G, gentamycin, neomycin, tetracycline, cefotaxime, and cefoxitin inhibited 90% of Prevotella intermedia, whereas bacitracin, chloramphenicol, and polymyxin inhibited 80% of Prevotella intermedia. Thus, only 10% of Prevotella intermedia were resistant to these antibiotics. Conclusion: The present study confirms that Prevotella intermedia is associated with chronic periodontitis and AMI.

Abstract:

ABSTRACT The present study investigated the β-lactamase production of 73Prevotella intermedia, 84 Prevotella nigrescens, and 14 Prevotella pallens isolates and their in vitro susceptibilities to six antimicrobial agents. TheP. intermedia and P. nigrescens isolates were recovered from oral and extraoral samples obtained from subjects in two geographic locations from 1985 to 1995. The clonality of the β-lactamase-positive and β-lactamase-negative isolates and the clustering of the genotypes were studied by arbitrarily primed-PCR fingerprinting. β-Lactamase production was detected in 29% ofP. intermedia isolates, 29% of P. nigrescensisolates, and 57% of P. pallens isolates. No difference in the frequencies of β-lactamase production by P. intermedia and P. nigrescens between isolates from oral and extraoral sites, between isolates obtained at different time periods, or between P. intermedia isolates from different geographic locations was observed. However, the P. nigrescens isolates from the United States were significantly more frequently (P = 0.015) β-lactamase positive than those from Finland. No association between the genotypes and β-lactamase production or between the genotypes and the sources of the isolates was found. The penicillin G MICs at which 90% of the isolates were inhibited were 8 μg/ml for P. intermedia, 8 μg/ml for P. nigrescens, and 16 μg/ml for P. pallens. For the β-lactamase-negative isolates, the corresponding values were 0.031, 0.031, and 0.125 μg/ml, and for the β-lactamase-positive isolates, the corresponding values were 16, 8, and 32 μg/ml. All isolates were susceptible to amoxicillin-clavulanate, cefoxitin, metronidazole, azithromycin, and trovafloxacin. The MICs of amoxicillin-clavulanate and cefoxitin were relatively higher for the β-lactamase-positive population than for the β-lactamase-negative population.

Abstract:

Purpose: A relationship between the distribution of periodontal bacteria species and malodor in children has not been sufficiently investigated. The present study was undertaken to determine the presence of 3 periodontopathic bacteria (Prevotella spp. P. intermedia, P. nigrescens, P. melaninogenica) in the supragingival plaques of 3 to 16-year-old children with different oral health conditions and oral malodor. Methods: The number of decayed and filled primary teeth (df) and Decayed, Missing and Filled permanent teeth (DMF),Papillary Marginal and Attached gingivitis (PMA) index, Oral Hygiene Index (OHI), and oral malodor of each subject were determined prior to the collection of supragingival plaques. Three periodontopathic bacteria(P. intermedia, P. nigrescens, P. melaninogenica ) in supragingival plaques were detected by using an immunoslot blot assay with monoclonal antibodies specific for each microorganism. Findings: The frequencies of periodontopathic bacteria in children with and without caries were not significantly different from each other. Positivity for P. intermedia, but not for P. nigrescens or P. melaninogenica was correlated with oral malodor. Oral malodor was also correlated with the debris index, a component of OHI. The group with the higher OHI showed a higher prevalence of periodontopathic bacteria. For the 3 periodontopathic bacteria in the subjects tested, plaques positive for any of them were not age related. However,the frequencies of all 3 periodontopathic bacteria were the highest in the 3-6-year olds. Conclusion: The supragingival plaques in children can harbor 3 species of periodontopathic bacteria, P. intermedia,P. nigrescens, and P. melaninogenica.

Abstract:

Two anaerobic, pigmented, non-spore-forming, Gram-stain-negative, rod-shaped strains isolated from the human oral cavity, OMA31T and OMA130, were characterized by determining their phenotypic and biochemical features, cellular fatty acid profiles and phylogenetic positions based on 16S rRNA gene sequence analysis. 16S rRNA gene sequence analysis showed that the new isolates belonged to a single species of the genus Prevotella. The two isolates showed 100 % 16S rRNA gene sequence similarity with each other and were most closely related to Prevotella intermedia ATCC 25611T with 96.4 % 16S rRNA gene sequence similarity; the next most closely related strains to the isolates were Prevotella pallens AHN 10371T (96.1 %) and Prevotella falsenii JCM 15124T (95.3 %). Phenotypic and biochemical characteristics of the isolates were the same as those of P. intermedia JCM 12248T, P. falsenii JCM 15124T and Prevotella nigrescens JCM 12250T. The isolates could be differentiated from P. pallens JCM 11140T by mannose fermentation and α-fucosidase activity. Conventional biochemical tests were unable to differentiate the new isolates from P. intermedia, P. falsenii and P. nigrescens. However, hsp60 gene sequence analysis suggested that strain OMA31T was not a representative of P. intermedia, P. pallens, P. falsenii or P. nigrescens. Based on these data, a novel species of the genus Prevotella, Prevotella aurantiaca sp. nov., is proposed, with OMA31T (=JCM 15754T=CCUG 57723T) as the type strain.

Abstract:

La enfermedad periodontal causa la pérdida de dientes en las mujeres embarazadas. Existe mucha evidencia que relaciona al embarazo con el desarrollo de las enfermedades periodontales, debido a la relación entre las hormonas sexuales con los tejidos periodontales; sin embargo, lo que llama la atención es la afinidad que hay entre estas hormonas con la prevalencia de la bacteria Prevotella intermedia. En tal sentido, se realizó una revisión bibliográfica actualizada con el objetivo de analizar si existe relación entre la presencia de la Prevotella intermedia con el desarrollo y la magnificación de las enfermedades periodontales en las mujeres embarazadas. Tomando en cuenta la evidencia científica analizada, se llegó a la conclusión que sí hay relación entre la Prevotella intermedia y el desarrollo y magnificación de las enfermedades periodontales durante la etapa del embarazo. Por lo cual, es siempre recomendable realizar la etapa preventiva y no quirúrgica del tratamiento.

Abstract:

Pendahuluan: Prevotella intermedia merupakan salah satu bakteri utama pada penyakit periimplantitis. Periimplantitis merupakan inflamasi jaringan lunak dan keras disekitar implan yang dapat dicegah menggunakan ekstrak tanaman antibakteri. Salah satunya yaitu kulit jeruk nipis, yang dapat menghambat proses inflamasi karena mengandung alkaloid, steroid, saponin, flavonoid, tanin sebagai senyawa antibakteri. Penelitian ini bertujuan untuk mengetahui peranan antibakteri kulit jeruk nipis dengan mengukur Konsentrasi Hambat Minimal (KHM) dan Konsentrasi Bunuh Minimal (KBM) ekstrak kulit jeruk nipis terhadap pertumbuhan bakteri Prevotella intermedia. Metode: Eksperimental laboratorium dengan rancangan penelitian post test only control group design. Pengujian KHM dan KBM dilakukan dengan metode dilusi, kulit jeruk nipis dimaserasi menggunakan pelarut etanol 70% sehingga didapatkan ekstrak kulit jeruk nipis dengan konsentrasi 0,78, 1,56, 3,125, 6,25, 12,5, 25, 50, dan 100% dengan chlorhexidine sebagai kontrol positif dan akuades sebagai kontrol negatif. Media kultur bakteri menggunakan Tripton Soya Agar. Hasil: Berdasarkan analisis statistik menggunakan Kruskal Wallis menunjukkan perbedaan penurunan jumlah koloni bakteri yang signifikan (p=0,0001) pada KBM dan KHM dari berbagai konsentrasi ekstrak kulit jeruk nipis terhadap pertumbuhan bakteri Prevotella intermedia, uji lanjutan Mann Whitney menunjukkan perbedaan penurunan jumlah koloni bakteri yang signifikan (p=0,021) antar masing-masing konsentrasi dan kelompok kontrol. Simpulan: Konsentrasi hambat minimal ekstrak kulit jeruk nipis terhadap bakteri Prevotella intermedia 12,5%, konsentrasi bunuh minimalnya 25%. Kata kunci: agen antibakteri; ekstrak jeruk nipis; Prevotella intermediaABSTRACTIntroduction: Prevotella intermedia is one of the main bacteria in periimplantitis. Periimplantitis is inflammation of the soft and hard tissues around the implant that can be prevented using antibacterial plant extracts. One of them is lime peel, which can inhibit the inflammatory process due to its alkaloids, steroids, saponins, flavonoids, and tannins as antibacterial compounds. This study was aimed to determine the antibacterial activity of lime peel by measuring the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of lime peel extract on the growth of Prevotella intermedia. Methods: Experimental laboratory with post-test only control group design. The MIC and MBC tests were performed by the dilution method. The lime peel was macerated using 70% ethanol solvent to obtain lime peel extract with concentrations of 0.78, 1.56, 3.125, 6.25, 12.5, 25, 50, and 100% with chlorhexidine as a positive control and aquadest as a negative control. Bacterial culture media using Tripton Soy Agar. Results: Based on statistical analysis using Kruskal Wallis showed a significant difference in the decrease of the number of bacterial colonies (p=0.0001) in MBC and MIC from various concentrations of lime peel extract on the growth of Prevotella intermedia bacteria. Furthermore, the Mann Whitney follow-up test showed differences in the decrease of the number of bacterial colonies, which was significant (p=0.021) between each concentration and control group. Conclusions: The minimum inhibitory concentration of lime peel extract towards the growth of Prevotella intermedia was 12.5%, with the minimum bactericidal concentration of 25%.

Abstract:

The haem pigment of Porphyromonas gingivalis is composed of μ-oxo bishaem, [Fe(III)PPIX]2O, but the nature of that generated by Prevotella species has not been established. Mössbauer, Raman and UV-visible spectrophotometry were used to characterize the haem pigment of Prevotella intermedia and Prevotella nigrescens. Mössbauer and Raman spectroscopy revealed the major haem species to be monomeric iron protoporphyrin IX, Fe(III)PPIX.OH (haematin). The terminal growth pH of both species on blood agar was between 5·8 and 6·0, which favours the formation and maintenance of monomeric Fe(III)PPIX.OH. Incubation of Pr. nigrescens and Pr. intermedia with oxyhaemoglobin at pH 6·5 resulted in formation of aquomethaemoglobin which was degraded to generate Fe(III)PPIX.OH which in turn became cell-associated, whilst incubation at pH 7·5 resulted in formation of [Fe(III)PPIX]2O. It is concluded that both Prevotella species degrade oxyhaemoglobin to form [Fe(III)PPIX]2O as an intermediate, which is converted to Fe(III)PPIX.OH through a depression in pH. The low pH encourages cell-surface deposition of insoluble Fe(III)PPIX.OH which would act as a barrier against oxygen and reactive oxygen species, and also protect against H2O2 through its inherent catalase activity.

Abstract:

ABSTRACT Recent evidence suggests that certain periodontal pathogens preferentially stimulate T cells expressing specific variable regions on the β chain (Vβ) of the T-cell receptor, which may indicate the presence of a superantigen. Superantigens are microbial proteins that activate large numbers of CD4+ T cells in a Vβ-specific manner. The purpose of this study was to determine whether Prevotella intermedia, a putative periodontal pathogen, activates populations of specific Vβ on CD4+ T cells. Among the bacterial strains tested,P. intermedia strain 17, a clinical isolate, induced the strongest proliferative response in peripheral blood mononuclear cells. Antibodies raised against whole cells of this organism blocked the proliferative activity. P. intermedia-induced proliferation was T-cell specific and required the presence of antigen-presenting cells. Flow cytometric analysis showed that CD4+ T-cell subsets expressing Vβ8, Vβ12, and Vβ17 expanded in response to P. intermedia strain 17. The ability of P. intermedia to stimulate CD4+-T-cell proliferation was further supported by the production profiles of key T-cell cytokines, gamma interferon and interleukin-2. The data collectively suggest that certain strains ofP. intermedia can activate Vβ-specific T cells in a manner similar to that of other known microbial superantigens.

Abstract:

Prevotella intermedia, a major periodontopathogen, has been shown to be resistant to many antibiotics. In the present study, we examined the effect of the FDA-approved iron chelators deferoxamine (DFO) and deferasirox (DFRA) against planktonic and biofilm cells of P. intermedia in order to evaluate the possibility of using these iron chelators as alternative control agents against P. intermedia. DFRA showed strong antimicrobial activity (MIC and MBC values of 0.16 mg ml−1) against planktonic P. intermedia. At subMICs, DFRA partially inhibited the bacterial growth and considerably prolonged the bacterial doubling time. DFO was unable to completely inhibit the bacterial growth in the concentration range tested and was not bactericidal. Crystal violet binding assay for the assessment of biofilm formation by P. intermedia showed that DFRA significantly decreased the biofilm-forming activity as well as the biofilm formation, while DFO was less effective. DFRA was chosen for further study. In the ATP-bioluminescent assay, which reflects viable cell counts, subMICs of DFRA significantly decreased the bioactivity of biofilms in a concentration-dependent manner. Under the scanning electron microscope, P. intermedia cells in DFRA-treated biofilm were significantly elongated compared to those in untreated biofilm. Further experiments are necessary to show that iron chelators may be used as a therapeutic agent for periodontal disease.

Abstract:

Abstratc: Bovine periodontitis is a progressive purulent infectious process associated with the presence of strictly and facultative anaerobic subgingival biofilm and epidemiologically related to soil management in large geographic areas of Brazil. This study aimed to detect species of the genera Porphyromonas and Prevotella, which occurr in periodontal pockets of cattle with lesions deeper than 5mm (n=26) and in gingival sulcus of animals considered periodontally healthy (n=25). Presence of the microorganisms was evaluated by independent-culture medium diagnostic method, using polymerase chain reaction (PCR) with specific primers of Porphyromonas asaccharolytica, P. endodontalis, P. gingivalis, P. gulae, Prevotella buccae, P. intermedia, P. loescheii, P. melaninogenica, P. nigrescens, P. oralis and P. tannerae. The species P. endodontalis (80.7%), P. melaninogenica (73.1%) and P. intermedia (61.5%) were the most predominant in samples of cattle with periodontitis. Regarding non-injured gingival sulcus of cattle, P. endodontalis (40%) and P. loeschei (40%) prevailed. Porphyromonas gingivalis, P. gulae and Prevotella tannerae were not detected in the 51 samples studied. Data evaluation by T test, enabled to verify that ocorrence of Porphyromonas asaccharolytica (p=0.000003), P. endodontalis (p=0.0023), Prevotella buccae (p=0.0017), P. intermedia (p=0.0020), P. melaninogenica (p=0.00006) and P. oralis (p=0.0028) is correlated with bovine periodontitis.

Abstract:

Background/Aims: Microbes reside in a number of body sites, including the oral cavity, and are associated with the progression of many systemic diseases. In this study, we aimed to investigate the effects of gout and hyperuricemia (HUA) on the composition of oral microbiomes. Methods: Analysis of the oral microbiota from 12 gout patients, 11 HUA patients, and 19 healthy control subjects was performed using a deep sequencing approach, and validation of significant changes in Prevotella intermedia and Serratia marcescens in new patient cohorts was performed using quantitative PCR (qPCR). Results: Our analysis indicated that both gout and HUA significantly altered the composition of the oral microbiome in patients. Patients with gout or HUA had significantly greater levels of salivary Prevotella intermedia but significantly lower levels of Serratia marcescens than healthy control subjects. Conclusion: We demonstrated the association between the oral microbiome and gout and HUA for the first time. In particular, 16S sequencing and qPCR analysis revealed significantly higher levels of oral Prevotella intermedia in gout/HUA patients, which suggests that these patients might be at risk for the development of periodontitis.
