Droseracae spp. is widely used in folk medicine. In the present study, the antimicrobial activities of the four Drosera rotundifolia L. (D8.11, D15.12, 18.10, 8.11) samples were investigated. The antimicrobial activities were determined by using agar disc diffusion method against grampositive bacteria (Bacillus thurigiensis, Staphylococcus aureus, Listeria monocytogenes) and gramnegative bacteria (Yersinia enterocolitica, Salmonella enteritidis).  The results of the disk diffusion method showed very different activity against all tested strains of microorganisms. The best antimicrobial activity of ethanolic extract Drosera rotundifolia L. against Salmonella enteritidis was found at Drosera rotundifolia (D8.11).
