Taschenbuch. Condición: Neu. Neuware -A proliferação das nanotecnologias, nomeadamente no sector alimentar, suscita preocupações quanto à sua segurança para a saúde humana. Devido ao seu tamanho nanométrico, estas partículas atravessam as barreiras biológicas, desde a boca até ao intestino. Este trabalho avalia o impacto toxicológico de duas misturas de nanopartículas (NPs): TiO¿/Ag e SiO¿/Ag sobre Escherichia coli, uma bactéria representativa da flora intestinal. Uma estirpe clínica foi isolada por coprocultura, identificada (API 20E) e depois exposta a diluições de NPs (0,125-1024 ¿g/ml). As placas de Petri em meio Hecktoen mostraram alterações fenotípicas após 24 horas de incubação a 37°C: crescimento reduzido, colónias mais pequenas, alterações morfológicas, perda de mobilidade e variações no agrupamento. Em determinadas concentrações (2 ¿g/mL TiO¿/Ag, 4 ¿g/mL SiO¿/Ag), foram observadas alterações genómicas (coloração de Gram), sugerindo um potencial desequilíbrio na microbiota intestinal. Esses resultados destacam a necessidade de mais estudos usando análise molecular (extração de DNA, sequenciamento) para entender melhor as mutações induzidas por NPs.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The proliferation of nanotechnologies, particularly in the food sector, raises concerns about their safety for human health. Due to their nanometric size, these particles cross biological barriers, from the mouth to the intestine. This work assesses the toxicological impact of two nanoparticle (NP) mixtures: TiO2/Ag and SiO2/Ag on Escherichia coli, a bacterium representative of the intestinal flora. A clinical strain was isolated by coproculture, identified (API 20E), then exposed to dilutions of NPs (0.125-1024 mig/ml). Petri dishes in Hecktoen medium revealed phenotypic alterations after 24 h incubation at 37°C: decreased growth, reduced colonies, morphological changes, loss of mobility and variations in grouping. At certain concentrations (2 mig/mL TiO2/Ag, 4 mig/mL SiO2/Ag), genomic changes were observed (Gram staining), suggesting a potential imbalance in the gut microbiota. These results highlight the need for further study by molecular analysis (DNA extraction, sequencing) to better understand NPs-induced mutations.…
