Abstract
Background: Today,
traditional medicine is developed globally as an important source for health
care of the world's population. The current study describes the antibacterial
activity of thymus commercial products against both Gram-positive
including Staphylococcus aureus, Streptococcus pyogenes and
Gram-negative bacteria including Escherichia coli, Pseudomonas
aeruginosa.
Methods: Two commercial
products of thymus with standard expiration date (and in three different
batch numbers) including anti-aphthous spray
and oral drop were purchased from the pharmacies of Tabriz city. Minimum
Inhibitory Concentration (MIC) and disk diffusion are used to investigate
the antibacterial efficiency of the mentioned products.
Results: The results of disk diffusion method
showed zones of growth inhibition against S. aureus and S. pyogenes for
the investigated products. Based on MICs, thymus oral drop had
inhibitory effects against S. aureus, S. pyogenes while anti-aphthous spray showed inhibitory
effects against S. aureus, S. pyogenes and P. aeruginosa.
The findings also indicated that the thymus anti-aphthous spray had more inhibitory effects than thymus
oral drop.
Conclusion: This study
showed that thymus can be used as an optimistic antibacterial agent
against the selected microorganisms.
