Objective: To investigate the prevalence, duration and aetiology of bacteraemia following dental extractions, analysing factors affecting its development. Subjects methods: The study group was composed 53 patients undergoing extractions under general anaesthesia. Peripheral venous blood samples were collected at baseline 30 s, 15 min 1 h after extractions. Samples inoculated into BACTEC PLUS aerobic anaerobic culture bottles processed in Bactec 9240. Subculture further identification...
Neither breakpoints (BPs) nor epidemiological cutoff values (ECVs) have been established for Candida spp. with anidulafungin, caspofungin, and micafungin when using the Sensititre YeastOne (SYO) broth dilution colorimetric method. In addition, reference caspofungin MICs so far proven to be unreliable. species wild-type (WT) MIC distributions (for microorganisms in a species/drug combination no detectable phenotypic resistance) were 6,007 albicans, 186 C. dubliniensis, 3,188 glabrata complex,...
Objective The current manuscript aims to determine the prevalence, duration and bacterial diversity of bacteraemia following dental extractions using conventional culture-dependent methods 16S rDNA pyrosequencing. Methods study group included 8 patients undergoing under general anaesthesia. Peripheral venous blood samples were collected at baseline, 30 seconds 15 minutes after extractions. Blood analysed for applying microbiological cultures aerobic anaerobic conditions as well...
To investigate the prevalence, duration and aetiology of bacteraemias following placement implants as well prophylactic efficacy a chlorhexidine digluconate (CHX) mouthrinse.Fifty patients undergoing implant were randomly distributed into two groups:30 with no intervention before surgery. CHX group: 20 who performed 0.2% mouthrinse Blood samples collected at baseline, 30 s after insertion 15 min completion suturing mucoperiosteal flap. Samples processed in Bactec 9240, subculture further...
Objective. To investigate the prevalence, duration, and etiology of bacteremia following dental extractions performed after a single administration Chlorhexidine mouthwash. Design Setting. A randomized, controlled trial in university hospital. Methods. series 106 patients with mental behavioral disabilities who underwent under general anesthesia were randomly assigned to control group or group. The exclusion criteria applied use antibiotics previous 3 months, oral antiseptics, any type...
Background: The prevalence and amounts of periodontal pathogens detected in bacteraemia samples after tooth brushing-induced by means four diagnostic technique, three based on culture one a molecular-based have been compared this study.Material Methods: Blood were collected from thirty-six subjects with different status (17 healthy, 10 gingivitis 9 periodontitis) at baseline 2 minutes brushing.Each sample was analyzed culture-based methods [direct anaerobic culturing (DAC), hemo-culture...
Objectives To investigate the development of post-extraction bacteraemia (PEB) after prophylactic use chlorhexidine (CHX). Patients and Methods A total 201 patients who underwent a tooth extraction were randomly distributed into four groups: 52 received no prophylaxis (CONTROL), 50 did mouthwash with 0.2% CHX before (CHX-MW), 51 subgingival irrigation 1% (CHX-MW/SUB_IR) 48 continuous supragingival (CHX-MW/SUPRA_IR). Peripheral venous blood samples collected at baseline, 30 seconds performing...
Summary Expert committees on bacterial endocarditis prophylaxis have provided differing opinions whether tracheal intubation is an ‘at‐risk’ manipulation. We studied the incidence of bacteraemia after orotracheal and nasotracheal intubation. The study group comprised 110 patients who underwent surgery under general anaesthesia. Venous blood samples were collected from each patient at baseline 30 s Samples processed with conventional microbiological techniques. Bacteraemia was detected in 13...
To evaluate the in vivo antimicrobial activity of chlorhexidine (CHX) saliva 7 h after its application using an epifluorescence microscopy technique.Fifteen volunteers performed a single mouthrinse with sterile water (SM-water) and 0.2% CHX (SM-0.2% CHX). Saliva samples were taken at 30 s 1, 3, 5 each application. The bacterial suspension was mixed SYTO 9/propidium iodide staining observed Olympus BX51 microscope. mean percentage viable bacteria calculated for sample.In comparison baseline...
Endoscopes represent the medical devices most commonly linked to health care-associated outbreaks and pseudo-outbreaks. Most of recent pseudo-outbreaks have resulted from contaminated automated endoscope reprocessors (AER) or use damaged malfunctioning bronchoscopes equipment.We investigated a pseudo-outbreak Pseudomonas putida Stenotrophomonas maltophilia recovered bronchial washing (BW) specimens obtained during bronchoscopy in unit.Samples were environmental surfaces endoscopy suite,...
Some evidence-based bundles have tried to standardize the management of Staphylococcus aureus bacteraemia (SAB) improve outcome. The aim our study was analyse additional impact on mortality a structured intervention in patients with SAB.Compliance bundle evaluated an ambispective cohort SAB, which included retrospective [including treated before and after implementation programme (no-BP BP, respectively)] prospective (i-BP), specific for application implemented. Multivariate logistic...
Treatment optimization for serious infections, such as Staphylococcus aureus bacteremia (SAB), is a challenge antimicrobial stewardship teams. Currently, SAB guidelines recommend completely intravenous therapy (CIT).The objective of the study was to analyze usefulness and safety oral sequential (OST) in SAB.We conducted retrospective, observational tertiary teaching hospital Spain. The inclusion criteria were complicated non-complicated monomicrobial an adequate duration therapy, with...
A new α-haemolytic streptococcal strain has been isolated from the dental plaque of a teenager with Down syndrome. Genetic and taxonomic analyses place this Streptococcus within oralis group. It is Gram-stain-positive, non-motile, non-spore-forming spherical alpha-haemolytic coccus arranged in chains, it ferments large number monosaccharides disaccharides, as well polymeric carbohydrates. differs biochemically closely related species due to its production α-galactosidase, β-galactosidase...
Systemic dissemination of oral bacteria to distant body sites may be the cause focal infections. The unsuitable use and overexposure antimicrobial therapy in clinical dental practice contribute worldwide problem resistance. aim this study was determine susceptibilities streptococci isolated from bloodstream after extractions against penicillin, ampicillin, amoxicillin, erythromycin, clindamycin, a new fluoroquinolone, moxifloxacin.Eighty-four patients who required were studied. Venous blood...
Two genes encoding for aminoglycoside-(3)-N-acctyltransferases (AAC(3)s) of different substrate patterns, present in multiresistance plasmids hospital strains Serratia marcescens and Escherichia coli isolated from urine, have been cloned characterized. The first, aacC1 with AAC(3)I activity, contained a 531 base pair open reading frame which encodes polypeptide 177 aminoacids 19,392 daltons, confirmed by minicell analysis. Its sequence differed previously published work four positions. Three...
Introduction: Obligate anaerobes are closely involved in the pathogenesis of oral and focal infections. The objective this study was to evaluate susceptibility profiles obligate origin telithromycin (TLM), moxifloxacin (MXF), other antibiotics that commonly used dentistry. Methods: sample comprised 172 isolated from saliva 43 adult volunteers. minimum inhibitory concentrations (MICs) were determined by agar dilution technique Brucella medium supplemented with vitamin K, haemin 5%...
