ABSTRACT
Objective To Study the effect of Yunnan Baiyao on the hemolysis and plasma coagulation ability of Staphylococcus aureus.ToseeknewmechanismofYunnanBaiyao′sapplicationonthebasisofanti‐virulence.Methods 0.5MCFbacterialiquidof Staphylococcus aureus standard strains(ATCC29213) were prepared and cultured in blood agar plates which containing Yunnan Baiyao of different concentrations at 37 ℃ for 24 h .Then the diameter of hemolysis rings were measured and recorded .0 .1 MCF bacteria liquids treated with Yunan Baiyao of different concentrations were prepared ,and 20μL of the bacteria liquid were added in‐to 80 μL plasma ,then cultivated at 37 ℃ for 24 h to observe the phenomenon of solidification .Results There was significant differ‐ence among the effects of Yunan Baiyao of different concentrations on the Staphylococcus aureus hemolytic rings(P0 .05) .Conclusion Yunnan baiyao can inhibit the growth of Staphylococcus aureus and its hemolytic ability but has no significant effect on plasma clot‐ting enzyme .
