Gheisari HR, Habibi H., Effect of Echinacea purpurea and Thymus vulgaris extracts on growth of pathogenic bacteria and fungi, Onl J Vet Res., 24(10): 600-607, 2020. Air-dried Echinacea purpurea and Thymus vulgaris were ground to fine powder for extract by methanol Soxhelet to 20mg/ml. Both extracts exhibited minimum inhibitory (MIC) and MFC against Listeria monocytogenes and Staphylococcus aureus but Thymus vulgaris had greater effects on Salmonella typhimorium and Escherichia coli O157: H7. Echinacea purpurea inhibited subtilis and Proteus vulgaris were affected more by extract. Only T vulgaris inhibited fungi but at very high concentrations (MIC = 40mg/ml, MFC = 160mg/ml).
Key words: Echinacea purpurea; Thymus vulgaris; Antimicrobial activities; Food pathogens.
