Resumen
El presente estudio logró analizar la actividad antibacteriana y antimicótica del extracto alcohólico y acuoso, obtenido por maceración del rizoma de la planta calaguala (Phlebodium pseudoaureum). Se comparó contra antibióticos seleccionados, utilizando un grupo de cepas control para el estudio en común: Staphylococcus aureus ATCC 29213, E. coli ATCC 25922 y Cándida albicans ATCC 10231”. Analizándose por el método de difusión en placa se postula la hipótesis de que el rizoma de la planta calaguala (Phlebodium pseudoaureum) contiene metabolitos secundarios, que presentan una actividad antibacteriana y antimicótica. El presente estudio demostró la actividad antibacteriana de la planta calaguala (Phlebodium pseudoaureum) en extracto alcohólico, que se determinó por el método de difusión con un rango de sensibilidad aceptable frente al microorganismo S. aureus y C. albicans según la norma CLSI que sirve de guía para el estudio.

It was compared against selected antibiotics, using a group of control strains for the common study: Staphylococcus aureus ATCC 29213, E. coli ATCC 25922 and Candida albicans ATCC 10231 ". Analyzing by the method of diffusion in plaque the hypothesis was postulated that the rhizome of the plant calaguala (Phlebodium pseudoaureum) contains secondary metabolites, with antibacterial and antifungal activity. The present study showed the antibacterial activity of the plant calaguala (Phlebodium pseudoaureum) in alcoholic extract, which was determined by the diffusion method with an acceptable range of sensitivity against the microorganism S. aureus and C. albicans according to the standard CLSI wed as an guide for the study.
