Enterobacteris en productes vegetals frescos: resistències als antibiòtics
2015
En aquest treball s’ha estudiat la presència d’enterobacteris en productes vegetals frescos que poden consumir-se directament, sense tractaments que poden afectar a la viabilitat dels microorganismes presents en aquests vegetals. Com material d’estudi s’han seleccionat una sèrie de verdures i hortalisses que habitualment poden consumir-se crues (tomates, enciams, rúcula, canonges, etc.), adquirides en distints establiments de la ciutat de València i els seus voltants, ja que la zona de l’horta de València es caracteritza, a més de per la qualitat i quantitat de la producció hortícola, per l’ús de pràctiques agrícoles (com l’ús de fem com adob) que afavoreixen la contaminació dels vegetals a…
Documento de consenso sobre el tratamiento antimicrobiano de las infecciones bacterianas odontogénicas
2005
Las infecciones de la cavidad bucal son un problema de salud pública frecuente y motivo constante de prescripción antibiótica; el 10% de los antibióticos se emplean para tratar este problema. Sin embargo, hasta la fecha son pocos los estudios realizados para determinar su incidencia. Asímismo, su relación con ciertas enfermedades sistémicas (cardiacas, endocrinas, etc...) confiere a estas patologías una importancia vital. A pesar de la reconocida frecuencia e importancia de las infecciones odontogénicas, llama la atención la actual dispersión de criterio en varios aspectos referentes a su clasificación, terminología y recomendaciones terapéuticas. El objetivo principal de este documento, re…
Microbiota Depletion Promotes Human Rotavirus Replication in an Adult Mouse Model
2021
Intestinal microbiota-virus-host interaction has emerged as a key factor in mediating enteric virus pathogenicity. With the aim of analyzing whether human gut bacteria improve the inefficient replication of human rotavirus in mice, we performed fecal microbiota transplant (FMT) with healthy infants as donors in antibiotic-treated mice. We showed that a simple antibiotic treatment, irrespective of FMT, resulted in viral shedding for 6 days after challenge with the human rotavirus G1P[8] genotype Wa strain (RVwa). Rotavirus titers in feces were also significantly higher in antibiotic-treated animals with or without FMT but they were decreased in animals subject to self-FMT, where a partial re…
Use of antibiotics by spanish dentists receiving postgraduate training in endodontics
2018
Background The incidence of endodontic infections is high. The contribution of Endodontics to the global problem of antibiotic resistance could be significant. The ESE, together with the World Health Organization, are promoting the World Antibiotic Awareness Week (13-19 November 2017) to promote the appropriate use of systemic antibiotics in Endodontics. The objective of this study was to determine the prescription pattern of antibiotics in the treatment of endodontic infections of Spanish dentists attending specialization programs in Endodontics. Material and Methods Dentists from five Spanish endodontic postgraduate programs were requested to answer a one-page questionnaire surveying abou…
Patient perception about the need for antibiotics after tooth extractions: A cross-sectional study
2021
Background: Although the current scientific literature does not support the routine use of antibiotics after dental extractions, patients believe that these drugs offer clear benefit during the postoperative period. The main objective of this study was to describe patient perception of the need for antibiotics after routine tooth extraction and to assess knowledge about the benefits and adverse effects of antibiotic therapy. Material and methods: A cross-sectional study was carried out. A total of 452 participants requiring tooth extraction and seen in the Dental Clinic of the University of Barcelona (Barcelona, Spain) were given a specific questionnaire on the need for antibiotics after de…
Antibiotic prescription for the prevention and treatment of postoperative complications after routine dental implant placement. A cross-sectional stu…
2018
Background As there are no established guidelines for antibiotic prescription after dental implant placement a study was made to determine the current prescribing habits of several groups of practitioners regarding antibiotics to prevent and/or treat postoperative complications - early failures and infections - in relation to routine dental implant placement. Material and methods An electronic survey was sent to postgraduate students and professionals with experience in routine dental implant placement who practice in Spain. The questions asked were related to whether antibiotics were routinely prescribed either pre- or postoperatively to prevent and/or treat postoperative complications dur…
Antibiotics as selectors and accelerators 1 of diversity in the mechanisms of resistance: from the resistome to genetic plasticity in the β-lactamase…
2013
Antibiotics and antibiotic resistance determinants, natural molecules closely related to bacterial physiology and consistent with an ancient origin, are not only present in antibiotic-producing bacteria. Throughput sequencing technologies have revealed an unexpected reservoir of antibiotic resistance in the environment. These data suggest that co-evolution between antibiotic and antibiotic resistance genes has occurred since the beginning of time. This evolutionary race has probably been slow because of highly regulated processes and low antibiotic concentrations. Therefore to understand this global problem, a new variable must be introduced, that the antibiotic resistance is a natural even…
Suplementos probióticos en enfermedades del entorno gastrointestinal por alteración de la microbiota tras la antibioterapia

La suplementación con probióticos podría emplearse terapéuticamente para regular o evitar esta disbiosis. Objetivo: Analizar la información relevante sobre el uso de probióticos como coadyuvante en el tratamiento con antibióticos en enfermedades del entorno gastrointestinal que pueden alterar su microbiota. Métodos: Revisión bibliográfica en bases de datos científicas de artículos relacionados con el tema y publicados entre enero de 2010 a junio de 2020. Se encontraron 132 artículos, 43 se incluyeron tras cumplir los criterios de selección, relevan…
Determination of crown discoloration and fluorescence induced by different medications used in regenerative endodontic procedures: An ex vivo study
2021
Background Crown discoloration is an undesirable side effect of the use of triple antibiotic paste (TAP) in regenerative endodontic procedures (REPs). The aim of this ex vivo study was to assess the potential for tooth discoloration and induction of fluorescence associated with the use of TAP containing either doxycycline (DOX) or clindamycin (CLIN), and of calcium hydroxide (Ca(OH)2), by spectrophotometric analysis and confocal laser scanning microscopy (CLSM). Material and methods A total of forty single-rooted human teeth extracted by therapeutic indication were used. The root canals were enlarged using the step-back technique up to a K #80 file and were randomly divided into four experi…
Replication of Human Norovirus in Mice after Antibiotic-Mediated Intestinal Bacteria Depletion
2022
Human noroviruses (HuNoVs) are the main cause of acute gastroenteritis causing more than 50,000 deaths per year. Recent evidence shows that the gut microbiota plays a key role in enteric virus infectivity. In this context, we tested whether microbiota depletion or microbiota replacement with that of human individuals susceptible to HuNoVs infection could favor viral replication in mice. Four groups of mice (n = 5) were used, including a control group and three groups that were treated with antibiotics to eliminate the autochthonous intestinal microbiota. Two of the antibiotic-treated groups received fecal microbiota transplantation from a pool of feces from infants (age 1-3 months) or an au…
