Abstract
In order to investigate the antimicrobial effects of Iranian herbal essences of Zataria multiflora Boiss., Myrtus communis L. and Eucalyptus officinalis, this research was conducted under CLSI guidelines in vitro situation. Since Streptococcus pneumoniae, Moraxella catarrhalis and Haemophilus influenzae are highly involved in Sinusitis and Bronchitis, the antibacterial effects of the essences were investigated on these species. Antibiotic susceptibility testing was performed by disk diffusion method for the essential oils and of determination Minimum Inhibitory Concentration (MIC) was carried out by serial dilutions. Zataria multiflora was effective against all the tested bacterias e.g. Streptococcus pneumoniae (52mm), Moraxella catarrhalis (55mm) and Haemophilus influenzae (40mm) based on disk diffusion method. Furthermore, the highly effective inhibition of Myrtus communis was on Moraxella catarrhalis (50 mm) (MIC≥78.66 µg/ml). This study showed that the herbal essences are very active against Streptococcus pneumoniae, Moraxella catarrhalis and Haemophilus influenzae in vitro situation. This confirms the application of herbal medicines for treating a range of infectious diseases in ancient times.
