This study was intended to evaluate the antimicrobial activity of crude extract of Arctium lappa on some pathogenic bacterial species in vitro. The study was included different types of gram-positive and gram-negative bacteria such as (Pseudomonous aerogenosa, Staphylococcus aureus, Salmonella typhimurium, E.coli, Listeria monocytogene, Streptococcus pyogenes, Brucella abortus and Bacillus anthracis). The results of this study revealed either classified resistant or sensitive according to Arctium lappa concentration. A significant difference at (P0.05) were appeared, which indicated that gram positive bacteria had more resistant than gram negative bacteria, whereas sensitivity were counted more gram negative bacteria than gram positive bacteria. In conclusion, the results of this study revealed that Arctium lappa crude extract has inhibitory effects against different types of pathogenic bacteria with some variability in its activity depending on the concentration of extract. |
