Ethnobotanical knowledge of many plants with appreciated antimicrobial actions requires scientific evidence about their activities. Many species from the vascular flora of Entre Ríos (Argentina), are used in the popular culture for the treatment of dermatitis, infections, pimples and other affections. Eleven of them were selected to be studied: Acacia bonariensis, Baccharis articulata, Blepharocalyx salicifolius, Castela tweedii, Eichhornia crassipes, Erythrina crista – galli, Gaillardia megapotamica, Hydrocotyle bonariensis, Phytolacca dioica, Senna scabriuscula and Typha latifolia. Dichloromethane extracts were assayed against a group of standard and clinical strains of Gram + and Gram - bacteria using the diffusion method in solid media. Results show that extracts of aerial parts of E. crassipes and bark of E. crista–galli were active gainst Bacillus subtilis and Staphylococcus aureus, while the extracts of aerial parts of H. bonariensis, B. articulata, B. salicifolius and roots of T. latifolia, were active against B. subtilis. The assays of B. salicifolia and E. crassipes show activity against a clinical methicillin resistant strain of S. aureus (MRSA).
