title: Antimicrobial potential of the Ethiopian Thymus schimperi essential oil in comparison with others against certain fungal and bacterial species.
abstract: BACKGROUND
  To evaluate the in vitro activities of Ethiopian Thymus schimperi with other three hydro distilled essential oils against Dermatophytes (Tricophyton spp. and Microsporum spp.) and other pathogenic micro organisms.
  
  
  METHODS
  The studies were carried out using Agar disk diffusion method for screening the most effective essential oils and Agar dilution to determine Minimum Inhibitory Concentration (MIC) of the essential oils.
  
  
  RESULTS
  Essential oils of T. schimperi and Cinnamomum zeylanicum were highly active against tested organisms. The MIC were in the range of 0.08 μl/ml to 0.31 μl/ml for T. schimperi, 0.31 μl/ml to 0.16 μl/ml for C. zeylanicum, 2.5 μl/ml to1.25 μl/ml for Citrus limon and 5 μl/ml to 2.5 μl/ml for Eucalyptus camaldulensis against Tricophyton spp. and Microsporum spp. T. schimperi and C. zeylanicum oils also showed antimicrobial effect against Candida albicans, Aspegilus niger, Rhodotorula rubra, Escherichia coli, Shigella spp., Bacillus spp. and Streptococci.
  
  
  CONCLUSIONS
  The Ethiopian T. schimperi oil had pronounced antifungal and antibacterial activities against all the tested microbes. Therefore, it is required further investigation in order to identify the active compounds and their clinical applications for treatment of tested organisms.
