Studies involving antimicrobial-coated endotracheal tubes are scarce, and new approaches to control multidrug-resistant Pseudomonas aeruginosa biofilm on these devices should be investigated. In this study, five P. bacteriophages from domestic sewage were isolated. All of them belong the order Caudovirales, Myoviridae family. They pH heat stable produce 27 46 particles after a latent period 30 min at 37oC. Their dsDNA genome (ranging ⁓62 kb ⁓65 kb), encode 65 89 different putative proteins....
Mastitis is one of the factors that cause damage to production and processing milk. The aim this study was isolate species Staphylococcus aureus from milk samples 63 animals with mastitis, check your profile antimicrobial sensitivity antibiotics extract propolis at 30%. Of evaluated, 38 (60.32%) showed growth aureus. As for testing test, most efficient were gentamicin (10 ug), cephalexin (30 ug) ciprofloxacin 100% efficiency, followed by norfloxacin (94.6%). There 35 (92.10%) 30% inhibition...
Abstract The cross‐infections may occur during handling of dental elements, affecting the health practitioners and researchers. This study aimed to analyze influence storage medium temperature on bacterial contingent human teeth used for research purposes. Thirty were donated Human Teeth Biobank immediately after extraction. cleaned with tap water neutral soap. randomly distributed according solution (deionized water): at 4 °C (refrigerator) or −10 (freezer) stored individually in sterile...
Resumo Objetivo: Identificar os agentes antimicrobianos utilizados na prevenção da formação de biofilme em marcapassos artificiais. Métodos: Revisão literatura para responder a seguinte questão: “Quais são usados prevenir biofilmes artificiais?” As bases dados PubMed, Web of Science, Scopus, Science Direct, Cochrane, CINAHL, Embase e LILACS foram consultadas todos idiomas sem restrição tempo. Resultados: A amostra final apresentou cinco estudos primários, sendo maioria experimental....
Objective: To evaluate bacterial load of water using and not sodium hypochlorite aiming at control dental unit water. Method: Dental reservoirs from a clinic School Dentistry Ribeirão Preto -USP were filled with public-supply without solution 0.0003%, samples collected evaluated by Petrifilm™ AC (Aerobic Count) system 2014 to 2017. Results: No contamination was observed in the solution. However, detected reservoirs, air-water syringes high-speed outputs (without handpieces) disinfectant....
Biosafety in dentistry aims to combat cross-contamination and biofilm dental unit waterlines. The aim was investigate from a physical, chemical, mechanical biological perspective, protocol for using chemical products (citric acid, sodium bicarbonate chloride) improve maintain water quality Change microhardness corrosion tendency were observed stainless steel samples. On the polyurethane surfaces, there changes color, roughness. Anti-biofilm evaluations revealed significant reduction biomass,...
Objective: to propose a form for the assessment of cognitive and curriculum attributes about patient safety in undergraduate nursing students. Methodology: This is methodological character study, based on Multi-professional Patient Safety Curriculum Guide World Health Organization trackers terms identified literature. The study included 17 judges subject Brazilian higher education institutions who formed committee assess semantic idiomatic equivalence issues. Results: theoretical that...
Resumo Objetivo: Avaliar a influência do tempo de exposição e calibre na formação biofilme em cateteres urinários Foley (CUFs). Método: Pesquisa in vitro com amostras fragmentos CUFs látex siliconizado diferentes calibres (n° 14 n° 16 Frenchs). A urina artificial foi confeccionada, inoculada bactérias-padrão Staphylococcus aureus (ATCC 25923) Pseudomonas aeruginosa 27853) incubada 37 °C por 24 horas 72 horas. As análises foram realizadas meio cultura (carga bacteriana) microscopia eletrônica...
The disinfection procedures aim to reduce the microbial load, but there are doubts about risks of contamination spreading into lumens devices, such as three-way stopcocks (3-WS). This study aimed at an in vitro evaluation antibacterial procedure manual friction 3-WS intentionally contaminated and determine solution dispersion lumens. Laboratory experiments were developed two steps: bacterial spread through intentional with Staphylococcus aureus Pseudomonas aeruginosa, alcohol After saline...
Denture biofilm represents a potential source of microbial contamination/infection that has been combated by new hygiene methods. Bacteriophages have already related as growth controller, but dentures research is scarce. Objective: this evaluated if it possible to isolate bacteriophages from biofilm, and use an emergent way control growing. Method: samples were collected sixteen maxillary complete in aseptic zone brushing their internal surfaces using soft toothbrush. The suspensions...
Abstract Cross-infection in contrast injectors is still a subject under discussion with little understanding. This study evaluated the biosafety of non-return valves (NRVs). Initially, maximum pressure during backflow intact and disrupted flexible diaphragms (FDs) from NRVs, as well functionality connectors NRVs were verified. The performance air columns interposed by water was analyzed, diffusion distance crystal violet through measured. efficacy barrier to bacterial contamination...
Introduction: One of the major problems in health services is occurrence healthcare-associated infections (HAIs) by microorganisms resistant to various antimicrobials.Objectives: To describe frequency and susceptibility profile Pseudomonas aeruginosa Acinetobacter baumannii carbapenems hospital from Fundação Santa Casa de Franca, São Paulo, Brazil.Methods: The P. A. 304 clinical isolates between 2007 2012 was retrospectively analyzed a microbiology database at laboratory Brazil.Results: From...
This study investigated the effect of water at high temperature on physical and mechanical properties polyurethane biofilm removal, aiming for its applicability in dental unit waterlines. The evaluations were carried out after simulating a 1-year period daily immersion measured changes color, microhardness, surface roughness, tensile strength before reproducing disinfection protocol. For antibiofilm activity measurement, fragments waterline contaminated with Pseudomonas aeruginosa submitted...
