- Abstract
Tea tree oil is the essential product optained from Melaleuca alternifolia, with antiviral, antibacterial, antifungal and anti-inflammatory properties. The antimicrobial effect of the Melaleuca alternifolia extract was tested using standardized bacterial strains: Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes and Enterococcus faecalis) and gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis, Legionella pneumophila). The working methods were: the diffusion method (Kirby Bauer) which allows the determination of the minimum inhibitory concentration (CMI) and the spectrophotometric method to determine the minimum bactericidal concentration (CMB). Based on the inhibition rates, the antimicrobial effect of the Tea Tree Oil (TTO) extract decreases as regards the strains used, as follows: Salmonella enteritidis > Streptococcus pyogenes > Escherichia coli > Legionella pneumophila > Enterococcus faecalis > Pseudomonas aeruginosa > Staphylococcus aureus. The inhibition rate values determined upon application of the TTO extract confirm the results obtained for the inhibition rays. The obtained results strongly demonstrate the antibacterial properties of the TTO extract and highlight its use for other strains of pathogenic bacteria
