The Kirby–Bauer disk diffusion test for measuring zone diameters of bacterial growth inhibition was used. The fir oil derived from Silver fir <em>Abies alba</em> showed considerably more profound activity than the cedar oil and fir oil derived from Siberian fir <em>Abies sibirica</em>. Maximum antibacterial activity was shown by essential oil of silver fir oil against <em>Escherichia coli</em>, methicillin-sensitive <em>Staphylococcus aureus</em> (MSSA), and <em>Pseudomonas aeruginosa</em>. Silver fir essential oil was found to be active against <em>K. pneumoniae</em> while Siberian fir essential oil showed the mild activity of clear inhibition zone against <em>P. aeruginosa</em> and methicillin-sensitive <em>Staphylococcus aureus</em>. Silver fir essential oil has the highest antibacterial potential from all tested essential oils and could be a promising candidate concerning possible applicability in the prevention of bacterial growth. Moreover, essential oils may play an important role in the discovery of new drugs for the treatment of a wide range of pathogenic microorganisms in the near future.</p> ER -
