Muradova, Mariam. "Role of oral bacterial glycosidases in human flavor perception". Electronic Thesis or Diss., Bourgogne Franche-Comté, 2024. http://www.theses.fr/2024UBFCK054.
Testo completoGlycosidases, particularly β-glucosidases, catalyze the hydrolysis of glycosidic bonds, releasing sugar molecules and aglycones. In the human oral cavity, β-glucosidases from the oral microbiota have previously been proposed to release aromatic compounds.This thesis aims to identify bacterial oral glycosidases involved in aroma release. Seven glycosidases from the oral microbiota were identified, expressed, and purified, including those from Veillonella sp. (VsBGlu1 and VsBGal1), Prevotella sp. (PsBG1), Streptococcus pneumoniae (SpBG1), Actinomyces naeslundii (AnBG1), Streptococcus salivarius (SsBG1), and Granulicatella adiacens (GaBG1). Kinetic analysis showed that PsBG1 has high catalytic efficiency towards β-glucopyranosides and can hydrolyze various aromatic and aliphatic glucosides, releasing volatile compounds such as salicylaldehyde, octanol, and hexanol. X-ray crystallography analysis of PsBG1 revealed its characteristic glycoside hydrolase family 1 structure. Through co-crystallization with a glycerol molecule, a set of amino acids was proposed for their roles in substrate recognition and catalysis. In a complex food matrix, PsBG1 effectively hydrolyzed glycosidic substrates into volatile metabolites. The β-glucosidases from Actinomyces naeslundii and Granulicatella adiacens also showed activity towards aromatic glycoside substrates found in food products.This study provides a detailed characterization of human oral microbiota β-glucosidases, demonstrating their role in the hydrolysis of aroma precursors and their potential role in flavor perception

Testo completoResumo: O estreitamento da relação entre tutores e animais de companhia, nas últimas décadas, aumentou consideravelmente o risco de transmissão de patógenos dos animais para os humanos. A microbiota da cavidade oral de animais de companhia é polimicrobiana e estes agentes podem potencialmente infectar humanos pelas mordeduras ou contato direto com mucosas ou feridas de pele. No entanto, são escassas as informações sobre a identificação destes micro-organismos por técnicas moleculares (microbioma, proteômica). Ainda, o perfil de sensibilidade microbiana in vitro da microbiota bacteriana bucal de cães e a etiologia dos agentes envolvidos em mordeduras em humanos não são completamente elucidados, posto que muitos cães são errantes e evadem após a agressão. Com efeito, o presente estudo investigou a presença de agentes de origem bacteriana e fúngica na cavidade oral de 100 cães hígidos por técnicas de cultivo microbiano convencional, sequenciamento genético em larga escala (microbioma) e espectrometria de massas (MALDI-TOF MS), bem como investigou o perfil de sensibilidade/resistência in vitro dos isolados. Foram identificados 213 micro-organismos de origem bacteriana e 20 de origem fúngica. Os agentes bacterianos mais prevalentes no diagnóstico microbiológico e espectrometria de massas foram Staphylococcus pseudintermedius (40/100=40%), Streptococcus α-hemolítico (37/100=37%) e Pasteurella stomatis (22/100=22%).

Abstract: The close relationship between humans and companion animals in recent decades has strongly increased the risk of transmission of pathogens from pets-to-humans. The microbiota of the oral cavity from companion animals is polymicrobial and these agents may potentially infect humans through bites or by direct contact with mucous membranes or cutaneous lesions. Nonetheless, the identification of these microorganisms by molecular techniques (microbiome, proteomics) is scarce. Besides, the in vitro microbial susceptibility pattern of oral bacterial microbiota from dogs and the etiology of agents involved in human bites are not fully understood, since many dogs are homeless and/or evade after aggression. The present study investigated the presence of bacterial and fungal agents in the oral cavity of 100 healthy dogs based on conventional microbiological culture, large-scale DNA sequencing (microbiome), and matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS). In vitro antimicrobial susceptibility profile of the isolates was assessed as well. A total of 213 bacterial and 20 fungal microorganisms were identified. The most prevalent bacterial agents diagnosed by microbiological culture and mass spectrometry were Staphylococcus pseudintermedius (40/100=40%), α-hemolytic Streptococcus (37/100=37%), and Pasteurella stomatis (22/100=22%), whereas the most common genus of fungi was Aspergillus (10/100=10%).

Testo completoThe incidence of Alzheimer's disease (AD), the leading cause of neurocognitive disorders in the adult population, is increasing worldwide. To date, and despite the immense progress made over the last 30 years in understanding the neuropathological mechanisms, and in particular the accumulation of Tau and Beta-amyloid proteins, the question of the etiopathogeny and the various risk factors of AD remains widely debated. Among the risk factors studied, chronic inflammation and pathologies, particularly infectious ones, constitute particularly interesting avenues of research. Recent data from the literature show a significant link between periodontal disease and AD. The oral cavity harbours a varied microbiota which constitutes a permanent inflammatory reservoir favouring the systemic dissemination of bacterial, fungal and viral species. Several infectious agents are suspected of playing an etiological role in the inflammatory genesis and aggravation of neurodegenerative diseases, including AD; in particular, human herpes viruses (HHV) and numerous periodontopathogenic bacteria. Major periodontal pathogens have been detected in the brain lesions of deceased AD patients, suggesting an infectious and inflammatory connection between the oropharyngeal sphere and the brain. This thesis work is based on the assumption that the oral cavity represents a privileged observation space. The ORAMICAL study "Oral Microbiology in Alzheimer's patients" is a non-randomised case-control study conducted at the Nice University Hospital. It aims to study, at the periodontal level, the presence of a selected set of bacterial and viral species in people aged over 70 years, diagnosed or not with AD. The primary objective is to establish a periodontal signature, combining viruses and bacteria, that would be significantly associated with AD. The secondary objectives are to compare oral hygiene and oral status in each group of patients. Cases and controls were recruited during a dental consultation or following a consultation with a geriatrician at the Nice University Hospital. Periodontal samples were collected by oral swabbing of the tooth with the deepest periodontal pocket. Microbial DNA (11 in total, 7 viruses and 4 bacteria) was analysed by qPCR. Various clinical data, such as masticatory coefficient, presence of mobility, caries index or periodontal status measurement were also collected. This study protocol is reported according to the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT). The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) study guidelines were followed. A first feasibility phase was carried out on twenty patients, 13 cases and 11 controls, with no significant differences in age and sex. The oral status was significantly worse for the cases. The plaque index was significantly higher in AD patients than in controls, and their level of dependency was also significantly higher. This study highlights the marked presence of certain bacterial and viral species in the periodontal lesions of AD patients. The differences (Fisher exact test) concern Varicella-Zoster virus (VZV), Epstein-Barr virus (EBV), Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn), which are detected to a high degree of significance in the cases. Although still based on a modest number of participants, this study highlights for the first time the increased incidence of VZV at the oral level, associated with more consensual markers of periodontal dysbiosis like EBV, Pg and Fn

Testo completoDental caries is one of the most common multifactorial chronic diseases in the world. It results from the change in the composition of dental plaque, with a transition from symbiosis to dysbiosis. Our clinical research characterized, qualitatively and quantitatively by real-time chain polymerization reaction, the interdental microbiota of 50 adolescents aged from 15 to 17 years according to the carious risk. Among the 26 pathogens analyzed, none of the cariogenic bacteria tested showed significant differences according to the carious risk. Only 3 bacteria known mainly for their involvement in periodontal diseases (Streptococcus sobrinus, Eikenella corrodens and Tannerella forsythia) were significantly over-expressed in adolescents with high carious risk. These 3 oral bacteria appear as predictive markers of carious risk. Interdental quantification would improve carious risk classifications, prevent early carious lesions and stabilize existing lesions. In addition, some oral pathogens including Eikenella corrodens and Tannerella forsythia are known to be risk factors, aggravating factors and triggers of some systemic diseases. The implementation of daily interdental prophylaxis by using interdental brushes seems essential from adolescence to restore the symbiosis of the microbiota, prevent oral and systemic diseases as we have shown in adults aged 18 to 35 years

Os Transtornos alimentares (TA) como Anorexia Nervosa (AN) e Bulimia Nervosa (BN) são acompanhados de inúmeras alterações sistêmicas e bucais relacionadas ao comprometimento do estado nutricional e às práticas compensatórias inadequadas para o controle do peso. O objetivo deste estudo foi avaliar diversidade microbiológica existente na cavidade bucal de pacientes com estes transtornos, por meio de técnicas de cultivo e utilizando métodos moleculares independentes de cultivo. Foram incluídos no estudo 32 pacientes anoréxicos e 27 bulímicos, pareados com 59 indivíduos controle. Amostras de enxágüe bucal foram semeadas para a avaliação da prevalência de leveduras do gênero Candida, estafilococos, enterococos, estreptococcos do grupo mutans (EGM), lactobacilos, enterobactérias/pseudomonas. Espécies de Candida, estafilococos, enterococos, enterobactérias/pseudomonas foram identificadas pelo sistema API. Amostras de biofilme supragengival foram coletadas e utilizadas somente nos procedimentos moleculares. As contagens de microrganismos nos grupos foram comparadas por ANOVA/Mann-Whitney (5%). Houve diferença estatisticamente significantes (p<0,05) para as contagem de leveduras do gênero Candida, estafilococos, enterococos, EGM e lactobacilos entre o grupo TA e controle, mas não houve diferenças significativas para a prevalência de enterobactérias/pseudomonas (p=0,312). Pequena diferença entre os grupos foi observada na diversidade de espécies dos microrganismos estudados pelo método de cultivo. Avaliação molecular foi realizada pela ribotipagem por seqüenciamento do 16S rRNA bacteriano e regiões D1/D2 do 28S rRNA. Foram avaliados cerca de 3000 clones do grupo TA e 1500 clones do controle.

Este trabalho teve como objetivo avaliar as alterações microbiológicas que ocorrem nas superfícies dentárias, ao redor dos bráquetes, antes e durante o uso de aparelhos ortodônticos fixos e inferir as conseqüências de tais alterações nos dentes e no periodonto. Foram coletadas amostras de biofilme dentário de 18 indivíduos (médias de idades de 13,05 anos) que iniciariam o tratamento ortodôntico com aparelhos fixos metálicos em clínicas particulares de Brasília-DF. As amostras supragengivais iniciais foram obtidas da face vestibular dos dentes 11, 13, 15, 31, 33 e 35 antes da instalação do aparelho e as finais, foram coletadas das faces vestibulares dos mesmos dentes após aproximadamente 60 dias de tratamento. As amostras foram analisadas utilizando-se o método do “Checkerboard DNA-DNA hybridization” que viabilizou, por meio de sondas de DNA marcadas com a molécula não radioativa digoxigenina, a detecção simultânea de 40 espécies bacterianas, sendo três destas espécies cariogênicas e 37 periodontopatogênicas. Observou-se aumento estatisticamente significante na proporção e contagem dos micro-organismos periodontopatogênicos, no biofilme supragengival nos indivíduos do presente estudo. No entanto, não foram encontradas diferenças significativas na contagem e proporção das bactérias cariogênicas. Desta forma, é relevante considerar o risco aos quais as estruturas dentais estão expostas durante o tratamento ortodôntico. Para se evitar inflamações gengivais e perdas de suporte periodontal, os pacientes necessitam ser adequada e frequentemente orientados quanto à sua higiene bucal no transcurso da terapia ortodôntica. _________________________________________________________________________________ ABSTRACT
The aim of this study was to evaluate the microbiological changes that occur in labial tooth surfaces, around the brackets before and during the use of fixed orthodontic appliances and infer the consequences of such changes on teeth and periodontium. Biofilm samples were collected of 18 subjects (mean age of 13,05 years) who were about to start orthodontic treatment with fixed metallic appliances in private clinics in Brasilia-DF. Initial supragengival samples were obtained from the labial surface of teeth 11, 13, 15, 31, 33 and 35 before installing the appliance and the finals were collected from the labial surfaces of these teeth after approximately 60 days of treatment. The samples were analyzed using the method of "checkerboard DNA-DNA hybridization” that made by means of probes labeled with nonradioactive digoxigenin molecule, that detected, simultaneously 40 bacterial species, three of these cariogenic species and 37 periodontopathogenics species. There was a statistically significant increase in the proportion and count of periodontopathogenic microorganisms in supragingival biofilm in the subjects in this study. However, there were no significant differences in the counts and proportions of cariogenic bacteria. So, it is relevant to consider the risk to which dental structures are exposed during orthodontic treatment. In order to prevent gingival inflammation and attachment loss, patients need to be properly oriented about their bucal hygiene in the course of orthodontic treatment.

Pacientes hospitalizados, incluindo crianças e adultos em Unidades de Terapia Intensiva(UTI), sempre foram uma questão de saúde pública devido aos altos custos, sequelas e taxas de mortalidade. Este estudo clínico objetivou comparar a colonização da microbiota bucal de crianças não hospitalizadas saudáveis e de crianças hospitalizadas em Unidade de Terapia Intensiva Pediátrica(UTIP) antes e após implementação do protocolo preventivo de profilaxia bucal, bem como avaliar o conhecimento de cuidados bucais pelos profissionais intensivistas no Hospital Materno Infantil de Brasília(HMIB). Após aprovação pelo Comitê de Ética protocolo no 23/355/11, foi aplicado o questionário aos funcionários intensivistas e feito coleta das amostras de biofilme lingual com swab para posterior avaliação microbiológica de dois grupos: G1-crianças dentadas hospitalizadas em UTIP e G2- crianças dentadas, saudáveis e não hospitalizadas. Para o G1, duas avaliações foram realizadas: antes(G1i) e após três dias de cuidado profilático bucal com gluconato de clorexidina a 0,12%(G1f). Após os resultados das culturas microbianas, os dados foram tabulados. Para a análise estatística foi utilizado o Teste Exato de Fisher´s e Teste G - Williams com nível de siginificância de 5%. A maioria dos profissionais desta UTIP consideram importante a presença do cirurgião dentista na equipe intensivista e desconhecem a saliva artificial e a limpeza da língua. Bactérias patogênicas foram encontradas no G1, como Pseudomonas aeruginosa, Serratia marcescens, Klebsiella pneumoniae, Staphylococos aureus, com diferença estatisticamente significante entre os grupos G1i e G2(P = <.0001). Bactérias patogênicas(P = <.0001) e a presença de saburra lingual(P = .0004) reduziram significantemente no G1f para G1i. Bactéria patogênica no G1f foi similarmente encontrada no G2(P =.1403). Bactérias patogênicas foram encontradas com mais significância no grupo de crianças hospitalizadas do que no grupo de crianças não hospitalizadas e foram reduzidas após implantação do protocolo de higiene bucal, bem como a saburra de língua. Portanto, com base nos resultados obtidos pode-se concluir que protocolos de profilaxia bucal deveriam ser implantados em unidades de UTIPs e o cirurgião dentista deveria fazer parte da equipe multidisciplinar intensivista.
Hospitalized patients, including children in pediatric intensive care units (PICUs) as well as adults in intensive care units(ICUs), have always been a public health concern because of high costs, in addition to the increased rates of mortality and sequelae. This clinical study aimed to compare the oral microbial colonization in non-hospitalized healthy children and hospitalized children at pediatric intensive care unit-PICU before and after implementing a preventive oral care protocol, and to assess the knowledge of oral care intensivists pionais no as well as to assess the knowledge on oral health care procedures of the medical staff of the Children Mother Hospital of Brasilia(HMIB) Federal District, Brazil. After Ethic Comitte aproval under the number 23/355/11the questionary was done and the tongue biofilm swab was collected and tongue biofilm analysed. Two groups were analyzed: G1-hospitalized dentate children in PICU and G2-non-hospitalized healthy dentate children. For G1, two assessments were performed: before (G1i) and after three days after a stablishment of an oral care protocol at 12-hour intervals with 0.12% chlorhexidine (G1f). Microbiological evaluation was performed. Fisher’s exact and G-Williams tests were used with a significance level of five percent. Pathogenic bacteria were found in G1, such as Pseudomonas aeruginosa, Serratia marcescens, Klebsiella pneumoniae, Staphylococos aureus, with a significant difference between the groups G1i and G2 (P = <.0001). Pathogenic bacteria(P = <.0001) and the presence of tongue coating (P = .0004) significantly decreased in G1f to G1i. Bacteria in G1f were similar found in G2 (P = .1403). Pathogenic bacteria were more often present in hospitalized than non-hospitalized healthy dentate children and can be reduced by preventive oral care protocols. Therefore, based on the results, it could be concluded that protocols should be implemented on a regular basis in PICUs and dentist should be included in the ITU.

Testo completoRheumatic fever is the result of a Streptococcus pyogenes (group A -hemolytic Streptococcus) infection of the upper respiratory tract. Rheumatic heart disease is a rheumatic fever consequence and is elucidated by the molecular mimicry between human cardiac proteins and group A streptococcal proteins and carbohydrates association. The secondary prophylaxis with 1,200,000 U BPG every three weeks is used for prevention of recurrent rheumatic fever in developing countries. Valvar defects are a risk for infective endocarditis which is resulted of bacteriemia caused for oral infectious focuses in 40% of cases. Viridans streptococci are the predominant group recovered in infective endocarditis, specially Streptococcus sanguinis and Streptococcus oralis. The effect of chronic BPG wasnt studied with specificity to these pathogens yet. Therefore, the oral microbiota was evaluated, qualitatively and quantitatively, at 7 and 21 days after secondary prophylaxis with BPG to rheumatic fever (study group), in a hundred patients and in comparison to another hundred patients with coronary heart disease who never acquired rheumatic fever (control group). The species evaluated were divided in S. sanguinis, S. oralis and another Streptococcus species. It was collected samples of chewing-stimulated saliva (1ml) and transported in VMGA II S medium. The samples were cultured in pure and with penicillin G 5% sheep blood Columbia ágar (CNA), incubated for 72 hours in an atmosphere containing 5% CO2 at 35ºC. The strains that were suggestive to Streptococcus were identified by biochemical tests to confirm bacteria species and genus. Minimal inhibitory concentration was determined by Etest method and interpreted in accordance to Clinical and Laboratory Standards Institute. The results showed that there was no difference in S. sanguinis presence in all groups (P=0.40). S. oralis prevailed in 7 days BPG group in comparison to control group (P=0.01). The control group showed the highest number of others species in comparison to 7 and 21 days BPG (P<0.001). CFU/ml numbers of S. sanguinis, S. oralis and other species strains were compared in 7 and 21 days BPG to control group and there was no difference among themselves (P=0.96, P=0.60 and P=0.77; respectively). There was no difference in S. sanguinis and S. oralis MICs among the study and control groups (P=0.79 and P=0.13). All statistic tests were done at 5% significance level. It was concluded that S. oralis prevailed in 7 days BPG group in comparison to control group; other species of Viridans streptococci prevailed in control group. The number of CFU/mL did not differ in both studied groups; the penicillin susceptibility of S. sanguinis and S. oralis did not change by BPG every three weeks and, by the end, it was not observed hypersensitivity reactions to penicillin in neither of the patients of this study
