VIVOT, Eduardo P; SANCHEZ, Cecilia; CACIK, Francisco  and  SEQUIN, Christian. Antibacterial activity of medicinal plants in the flora of Entre Ríos (Argentina). Cienc. docencia tecnol. [online]. 2012, n.45, pp.131-146. ISSN 1851-1716.

Traditionally employed medicinal plants are a resource for new drugs needed to address microbiological conditions produced by the acquired resistance of microorganisms and the increased number of immunosuppressed people. The background of ethnobotanical flora of Entre Ríos includes numerous species used to cure infections. For the present study there were selected: Acacia bonariensis; Baccharis articulata; Blepharocalyx salicifolius; Castela tweedii; Eichhornia azurea; Eichhornia crassipes; Erythrina crista-galli; Gaillardia megapotamica var. scabiosoides; Hydrocotyle bonariensis; Ludwigia peploides; Pistia stratiotes; Phytolacca dioica; Porlieria microphylla; Senna scabriuscula; Schinus fasciculatus y Typha. We evaluated antibacterial activity of methanolic, hydroalcoholic and aqueous plant extracts by the diffusion method on solid medium using standarized bacterial strains to verify the sensitivity to these extracts. The results show antibacterial activity in vitro of numerous extracts of most species, and of several ones against a clinical strain of Streptococcus aureus methicillin resistant.
