LUJAN, María Claudia  y  PEREZ CORRAL, Cristina. Screening to evaluate the antibacterial and antimycotic activity in plants used in Argentinean folk medicine . Rev Cubana Farm [online]. 2008, vol.42, n.2, pp. 0-0. ISSN 1561-2988.

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.
