Sumario:This study aimed at evaluating the antibacterial activity of vegetable extracts in the control of the Staphylococcus aureus strains, using Disk Diffusion and Minimum Bactericidal Concentration (MBC) tests. The susceptibility of 52 S. aureus strains to the hydroethanolic extracts from the following plants: (1) Psidium guajava var. pomifera, (2) Hymenaea courbaril var. stilbocarpa, (3) Pothomorphe umbellata, (5) Bidens pilosa, was tested by the methodology based on the international standards of CLSI. By comparing the results from the action of extracts concentrations prepared in this experimental study, it was found that the B. pilosa showed a minor action; P. guajava var. pomifera, P. umbellata, presented results very close to each other and revealed median actions; H. courbaril var. stilbocarpa exhibited an action markedly higher than the other extracts and the control with ethanol. The in vitro effects of the extracts evidenced the presence of antibacterial active components. This study showed that hydroethanolic extracts from plants 1, 2, 3 and 5 hold in vitro antibacterial activity on Staphylococcus aureus MRSA and MSSA.
