| Summary: | The aim of this study is investigate the antimicrobial potential of plant species Schinus terebenthifolius, aroeira-red, on bacterial colonies of the exudate from pressure ulcers. Clinical samples were collectedfrom pressure ulcers of 6 patients of ADEFAL, plated on blood agar and after incubation an aliquot of suspension (in the range of 0.5 Mac Farland) was sown in Mueller-Hinton. The plant extracts were ground and standardized with the aid of sieves of 150 and 75 micrometers. The resulting powder was mixed with distilled water (10% m.v-1). To evaluate the antimicrobial activity, the disks were sterile filter paper with 10g of each extract. saturatresults referring to antibacterial activity of Schinus terebenthifolius (leaf) indicate an average inhibition zone of bacterial growth of 10.8 mm. Regarding Schinus terebenthifolius (stem) this study reveals the inefficiency of 10% of the extract as antimicrobial agent. This fact legitimizes the literature findings which show antimicrobial activity of plant extract Schinus terebenthifolius (stem), only when tested at a concentration above 10. The efficiency of the leaves of Schinus terebenthifolius supports the use of this product to minimize bacterial colonization and future infections. However, the results that showed antibacterial inactivity of Schinus terebenthifolius (stem) makes impracticable use this part of plant to treat pressure ulcers use of the extract of this plant a concentration of 10%.
