Abstract
The antimicrobial activities of the Methanol and its sub fractions of chloroform, Ethyl acetate, and water extracts of the roots, stem and leaves of Xanthium strumarium were conducted. The bacterial strain used were Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhymurium and Escherichia coli. The fungal species including Aspergillus fumigates, Fusarium solani, Aspergillus niger and Aspergillus flavus. Phytochemical analysis was also performed using the literature methods. All fractions of root extract showed significant activities against E. coli and Klebsiella pneumonia. Methanol, chloroform and water fraction of stem extract also found active against Salmonella typhymurium. Some fractions of stem, root and leaves extract were also give positive result against different fungi. In the present study, the selection of medicinal plant parts is based on the fact that most of these plant parts were not previously screened against multidrug resistant pathogenic
