Actividad antibacteriana de extractos de Gnaphaliumpoly cephalumMichx contraS. aureus, E. coli y P. aeruginosa
Contenido principal del artículo
Resumen
y la investigación de nuevos antibióticos han decrecido de forma tal que, en la actualidad, las opciones terapéuticas ante infecciones causadas por bacterias multirresistentes son realmente pocas. Por lo anterior es necesario buscar alternativas en fuentes naturales como las plantas, que representan uno de los mejores sustratos para la obtención de moléculas con actividad antimicrobiana.
