Title: Evaluation of antibacterial activity of Xanthium strumarium L. against pathogenic bacteria
Abstract: Bacterial infection is one of the most serious intrinsic bioactivity, by their ability to dissolve or diffuse global health issues in 21 century. Thus the present study was undertaken to investigate the antibacterial activity of Xanthium strumarium. Plant was extracted by using soxhlet extraction by using ethanol as a solvent extractor. Antibacterial activity of Xanthium strumarium was estimated against various bacterial pathogens. The results showed that ethanol extract of Xanthium strumarium exhibited antibacterial activity against gram positive and gram negative bacteria. Ethanol extract gave highest effect against Klebsiella spp and P. aregenosia. Then lower effect on S. aureus and Bacillus subtilis. The recent study showed that X. strumarium ethanolic extract can be used as microbial growth inhibitor against both gram positive and negative bacteria. Gram positive bacteria were found to be more resistant than gram negative bacteria, Also the studies determines that P. aregenosia was the most bacterial sensitive that produced the highest rate of inhibition zone, while the minimum inhibition zone with the same concentration was recorded by Staphylococcus aureus.
