Abstract
Backgrounds The current study aimed at investigating the antimicrobial effects of Vulgaris thymus ethanol extract on the important human pathogens.
Methods & Materials The thymus alcoholic extract was provided based on a standard protocol. The following standard bacteria were also provided: Streptococcus pyogenes ATCC 19615, Streptococcus pneumoniae ATCC 49619, S. saprophyticus ATCC15305, Hafnia alvei ATCC 51873, Acinetobacter baumannii ATCC 19606, Enterococcus faecalis ATCC 29212, Proteus mirabilis ATCC 35659, Serratia marcescens ATCC 274, Staphylococcus aureus ATCC 25923.
The minimum inhibitory concentration (MIC) of thymus ethanol extract on the bacteria was determined. The linear sensitivity of the bacteria against some antibiotics was also measured by the standard method of Kirby-Bauer disk diffusion.
Results The results showed that the thymus leaf alcoholic extract inhibited the bacterial growth in the evaluated concentrations. The MIC of 6/25 ppm was observed effective against S. pneumoniae, H. alvei, P. mirabilis, and S. marcescens.
Conclusion The results of the current study indicated the high effect of thymus alcoholic extract on the pathogenic bacteria. However, the medicinal application of plants requires further investigations.
