Abstract
En la actualidad, el uso de plantas medicinales como tratamiento alternativo es una práctica que ha aumentado significativamente (Luengo, 2008). La Organización Panamericana de la Salud (PAHO) define a la fitoterapia como el uso de las plantas medicinales, enteras o sus partes, secas o frescas, solas o asociadas; así como sus extractos y formulaciones, sin que se le adicionen otros principios activos industriales, para la prevención y/o tratamiento de problemas de salud. Dado el avalado uso de la fitoterapia en la medicina tradicional y de su importancia en la actualidad, uno de los objetivos de este trabajo, ha sido investigar la actividad antimicrobiana de nuevos fitocompuestos y diversos extractos vegetales, y su inclusión en formulaciones galénicas especialmente de aplicación tópica. Aunque en este estudio se incluyeron microorganismos y cepas que pueden producir infecciones de origen alimentario, infecciones respiratorias y urinarias, la mayor atención se centró en infecciones nosocomiales de difícil tratamiento, producidas por microorganismos multirresistentes, tales como la bacteria Gram positiva Staphylococcus aureus y la levadura (hongo) dimórfica Candida spp., especialmente la especie C. albicans...

Although this study included microorganisms and strains that can cause foodborne infections, respiratory and urinary infections, most attention was focused on difficult-to-treat nosocomial infections caused by multi-resistant microorganisms, such as the Gram-positive bacterium Staphylococcus aureus and the yeast (fungus) dimorphic Candida spp., especially the species C. albicans...
