%X Se realiz車 un cribado de 31 extractos de plantas utilizadas en medicina popular de Argentina para evaluar su actividad antibacteriana y antimic車tica, con el empleo de cepas de Micrococcus luteus, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus oxacilina sensible y Candida albicans. Se utilizaron distintas concentraciones de cefazolina, ampicilina y miconazol como antibi車ticos testigos. Se aplic車 el m谷todo de difusi車n en pozos de agar nutritivo. Se evalu車 la actividad de extractos acuosos de material vegetal. Las estructuras vegetativas y/o reproductivas de Conyza sumatrensis mostraron actividad contra todos los microorganismos tratados, mientras 7 taxones lo hicieron contra Proteus mirabilis y los extractos de la semilla de Bauhinia forficata subsp. pruinosa contra Staphylococcus aureus. Los resultados revestir赤an potencialidad farmacol車gica debido a la importancia cl赤nica de los microorganismos estudiados. A screening of 31 extracts of plants used in Argentine folk medicine for antimicrobial activity was made. The activity of aqueous extracts from vegetal material was assayed. Micrococcus luteus, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, oxacillin sensitive Staphylococcus aureus and Candida albicans were used as microorganisms. Different concentrations of cefazolin, ampicilin and miconazole were used as standard antibiotics. The agar-well diffusion method was used. Vegetative or reproductive structures of Conyza sumatrensis showed activity against all the microorganisms studied, whereas 7 taxons did it against Proteus mirabilis and seed extracts from Bauhinia forticata subsp. pruinosa did it against Staphylococcus aureus. The results should have pharmacological potentiality due to the clinical importance of the studied microorganisms.
