The Effects of Capsicum annuum L. Extract on the Control of Single and Dual Biofilms of Common Pathogenic Strains Causing Urinary Tract Infection

Background: biofilms directly influence the virulence and pathogenicity of a pathogen, it is optimal to employ a strategy that effectively inhibits the formation of biofilm. in this study, the antibacterial and anti-biofilm activities of extract capsicum annuum l were examined.materials and methods: the eight strains were isolated from urine culture of hospitalized patients; growth and biofilm formation of strains were determined by microtiterplate method. results: the results revealed that the concentrations of 5 and 10 mg/ml are the most restrain in the biofilm formation of the isolated plates.conclusion: results of this study suggest that the extract of c. annuum l may be useful alone to treat bacterial infections.
