5. Análise da atividade antimicrobiana dos óleos de dopaíba (C opaifera officinalis ) e da melaleuca ( Melaleuca alternifolia ) sobre Fusobacterium nucleatum e Por phyromonas gingivalis: determinação das concentrações inibitórias e bactericidas mínimas e efeito de concentrações subinibitórias sobre a agregação / Antimicrobial activity of copaiba (Copaifera officinalis) and melaleuca (Melaleuca alternifolia) oils on Porphyromonas gingivalis and Fusobacterium nucleatum: determination of minimum inhibitory and bactericidal concentrations and subinibitory effect on the aggregation
The oral cavity is a complex microbial habitat that has more than 500 bacterial species as components of the microbiota. Periodontal health is established when there is equilibrium between pathogens and host. The chlorhexidine digluconate is one of the most commonly used oral antibiotics, however, this substance has been associated with some undesirable side

6. Nanostructured systems containing an essential oil: protection against volatilization
The goal of this study was to evaluate the feasibility of preparing nanocapsules and nanoemulsions using tea tree oil as oily phase aiming to protect its volatilization. The nanostructures presented nanometric mean size (160-220 nm) with a polydispersity index below 0.25 and negative zeta potential. The pH values were 6.43 ± 0.37 and 5.98 ± 0.00 for nanoem

11. Mechanism of Action of Melaleuca alternifolia (Tea Tree) Oil on Staphylococcus aureus Determined by Time-Kill, Lysis, Leakage, and Salt Tolerance Assays and Electron Microscopy
The essential oil of Melaleuca alternifolia (tea tree) has broad-spectrum antimicrobial activity. The mechanisms of action of tea tree oil and three of its components, 1,8-cineole, terpinen-4-ol, and α-terpineol, against Staphylococcus aureus ATCC 9144 were investigated. Treatment with these agents at their MICs and two times their MICs, particularly treatm

12. In Vitro Activities of Ketoconazole, Econazole, Miconazole, and Melaleuca alternifolia (Tea Tree) Oil against Malassezia Species
The in vitro activities of ketoconazole, econazole, miconazole, and tea tree oil against 54 Malassezia isolates were determined by agar and broth dilution methods. Ketoconazole was more active than both econazole and miconazole, which showed very similar activities. M. furfur was the least susceptible species. M. sympodialis, M. slooffiae, M. globosa, and M.
