| Abstract: | The aim of this study was to determine the antibacterial and antifungal effect of two aqueous extracts obtained from different vegetal products of Tragopogon dubius Scop. species: Tragopogoni dubiusi radix and Tragopogoni dubiusi cauli et folium. Two aqueous extracts of different concentrations were obtained and tested on three bacterial strains (Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Streptococcus mutans – identified in saliva) and one fungal strain (Candida albicans ATCC 10231). In the case of Candida albicans, none of the two tested aqueous extracts of different concentrations had any inhibitory effect, which means they are not antifungal; on the other hand, strains of Staphylococcus aureus, Escherichia coli and Streptococcus mutans are sensible to the tested extracts. The results indicate that the two tested extracts have a moderate bacteriostatic effect. |
