Assessment of the Antiadertional Potential of Gautheria procumbes Essential Oil against Staphylococcus aureus

Nosocomial pneumonia is an infection of the lung parenchyma caused by bacteria and acquired after a 48–72 hour period of patient hospitalization. Among the bacterial species causing this condition is Staphylococcus aureus, a pathogen that has proven resistant to commonly used antibiotics. In view of this, new therapeutic alternatives are necessary, and phototherapy presents itself as a field of ample possibilities for study. The objective of this research was to evaluate the anti-adherent potential of Gaultheria procumbes essential oil against a strain of Staphylococcus aureus. To evaluate the Minimum Inhibitory Adherence Concentration (MIC) of the oil, the Muller Hinton broth with 5% sucrose, the Sa 101 strain of the bacterial species under study, as well as, the positive control with 0.12% chlorhexidine were used. The material was incubated at 37 °C for 24 hours for reading using fuchsin. As a result it was observed that the essential oil of Gaultheria procumbes inhibited the formation of biofilm in the proportion of 1:128, showing to be superior to the anti-adherent potential of chlorhexidine digluconate that inhibited in the proportion of 1:8. From the data, it was verified the anti-adherent potential of the essential oil of Gaultheria procumbes against the strain of Staphylococcus aureus, and thus, it can be an effective therapeutic option in intraoral antisepsis and surfaces of materials inserted in the oral cavity.
