Actividad antimicrobiana de cuatro variedades de plantas frente a patógenos de importancia clínica en ColombiaAntimicrobial activity of four varieties of plants against pathogens clinical significance in Colombia ResumenObjetivo. Evaluar la actividad antimicrobiana de los extractos de las plantas Bauhinia sp., Sambucus nigra, Eichhornia crassipes y Taraxacum officinale frente a patógenos de importancia clínica. Método. La metodología incluyó la adquisición, secado, maceración, molienda, preparación de los extractos crudos etanólicos y concentración por rotaevaporación, análisis fitoquimico y se separaron las fracciones por cromatografía en capa fina. Las pruebas antimicrobianas se realizaron con diferentes concentraciones de los extractos según las indicaciones de Clinical and Laboratory Standars Institute. Los microorganismos utilizados fueron Enterococcus faecium resistente a vancomicina, Streptococcus pneumoniae, Klebsiella pneumoniae con presencia de KPC, Providencia rettgeri con presencia de ESBLs, Pseudomonas aeruginosa, Enterobacter cloacae, Escherichia coli, Staphylococcus aureus β-lisina y Candida albicans. Resultados. Las cromatografías permitieron comprobar la presencia de flavonoides, terpenos, saponinas, fenoles, quinonas y alcaloides que han sido reportados con actividad antimicrobiana. En los ensayos de susceptibilidad antimicrobiana se encontró que los extractos presentaban diversos grados de inhibición frente a los microrganismos de estudio, siendo el más eficaz los tallos de T. officinale. Conclusión. Se puede concluir que los extractos vegetales podrían ser una alternativa de tratamiento para infecciones nosocomiales.Palabras claves: Resistencia bacteriana, plantas medicinales, extractos orgánicos, actividad antimicrobiana, ensayos de susceptibilidad, análisis fitoquímicos. AbstractObjective. To evaluate the antimicrobial activity of extracts of plants Bauhinia sp., Sambucus nigra, Taraxacum officinale and Eichhornia crassipes against clinically important pathogens. Method. The methodology included the acquisition, drying, soaking, grinding, preparing ethanolic crude extracts and concentration by rotary evaporation; phytochemical analysis, visualization by thin layer chromatography. Antimicrobial tests were performed with different concentrations of extracts as indicated by the Clinical and Laboratory Standards Institute. The microorganisms used
Zárate et al. Intervención educativa sobre virus de inmunodeficiencia humana en la comunidad habitante de c que asiste a un centro de acogida en la ciudad de Bogotá D.C. AbstractHIV is a world problem, according to the World Health Organization 36.7 million people infected by this virus, of which the greatest risk occurs in people who are in a state of neglect, by example the inhabitant street.
