Yanqiong Zhang

Abstract

[Objective] To study the antibacterial activity of the Compound YiZhiHao particles in vitro. [Methods] The culture of MH broth and MH agar plate with 2-fold dilutions of the drug. [Results] The minimal inhibitory concentration of Compound YiZhiHao particles on staphylococcus aureus, pneumococcus, β-hemolytic streptococcus and escherichia coli were 1∶16, 1∶16, 1∶8 and 1∶2, respectively. The minimal bactericidal concentration were 1∶8, 1∶8, 1∶4 and 1∶2, respectively. [Conclusion] The Compound YiZhiHao particles have obvious antibacterial activity to the staphylococcus aureus, β-hemolytic streptococcus and pneumococcus.
