Abstract: | As revealed in experiments on V. cholerae, the enzymatic link xanthine oxidase-xanthine produces a vibriostatic effect at the concentration of xanthine oxidase equal to 0.0125 g/l and a vibriocidal effect at the concentration of xanthine oxidase equal to 0.025 g/l in a medium with pH 7.5-7.6. In the presence of protein the antivibrionic activity of the xanthine oxidase link is decreased. The introduction of bivalent iron into the enzymatic link xanthine oxidase-xanthine enhances its vibriocidal action on V. cholerae. |
