“…The most common bacteria causing infections, especially nosocomial infections, are S. aureus, MRSA, E. coli and Pseudomonas aeruginosa, all of them resistant to most antibiotics [27] [37] [58]- [63]. The three extracts were effective against S. aureus and MRSA, in agreement with other studies testing the stem bark and leaves of A. occidentale [18] [19] [61], anacardic acid isolated from the cashew nut [10] [63] and CNSL [11].…”

Anacardium occidentale L., Anacardiaceae, is frequently used to treat infections. We evaluated the antimicrobial and antioxidant activity of extracts obtained from aerial parts of the plant in comparison with the extract prepared with the flowers. Ethanol extracts of the leaves (EEL), stem bark (EEB), and flowers (EEF) were prepared separately. The antimicrobial activity was evaluated by agar diffusion and broth dilution methods. The minimum bactericidal and fungicidal concentrations were determined against: Streptococcus mutans, Lactobacillus acidophilus, Staphylococcus aureus, MRSA, Enterococcus faecalis, Streptococcus pyogenes, Pseudomonas aeruginosa, Proteus mirabilis, Escherichia coli, Klebsiella pneumoniae, Helicobacter pylori, Salmonella choleraesuis, Candida albicans, and Candida tropicalis. The antioxidant activity of the extracts was evaluated based on their scavenger capacity of 2,2-diphenyl-1-picrylhydrazyle. The phytochemical profile was analyzed by colorimetric methods and by HPLC with UV detection. All extracts exhibited antioxidant and antimicrobial activity. Although, the EEF was the most effective since it inhibited the growth of all 14 microorganisms tested. Anacardic and galic acids were identified in all extracts as well phenolic compounds, triterpenes, flavones and xanthones. In conclusion, the extracts obtained from the aerial parts of A. occidentale, mainly the extract of flowers that was the most effective, are rich in bioactive metabolites that exert a potent antioxidant and antimicrobial effect. Taken together, the results indicate an important biotechnological potential of A. occidentale as a * Corresponding author. R.

“…P. aeruginosa is also commonly found in nosocomial infections since it is able to adhere to different materials, allowing it to contaminate catheters, ventilators, prosthetics and contact lenses. Because of the high resistance to antibiotics and the great amount of virulence factors, infections caused by this bacterium are difficult to 4 control .…”

“…A despeito dos avanços tecnológicos em relação ao desenvolvimento de drogas de maior potência antibacteriana, P. aeruginosa permanece como um dos agentes de infecções hospitalares mais prevalentes em todo mundo, principalmente devido às suas características naturais de resistência, mantendo-se em papel de destaque frente às dificuldades terapêuticas (Arruda, 1998 (Blanco, et al, 1990;Gransden, et al, 1990). (Nagao, et al, 2001).…”
