Influence of berberine sulfate on synthesis and expression of Pap fimbrial adhesin in uropathogenic Escherichia coli.

Journal Article (Journal Article)

We investigated the influence of berberine sulfate, an ancient Chinese antibiotic, upon the adhesion of uropathogenic Escherichia coli to erythrocytes and epithelial cells. Although berberine sulfate in increasing concentrations had no effect on bacterial growth or on the synthesis of major outer membrane proteins of the E. coli organisms, it increasingly blocked adhesion. The decreased adhesion was accompanied by a reduction in the synthesis of fimbrial subunits and in the expression of assembled fimbriae. These results suggest that the anti-infectious activity of berberine sulfate in E. coli-induced urinary tract infections may be mediated by the selective suppression of the synthesis and assembly of fimbriae by uropathogenic organisms.
