Antibacterial Effect of Shenju Lotion in Vitro / 医药导报

ABSTRACT

Objective To study the antibacterial effect of Shenju lotion in vitro. Methods The diameter of inhibition zone was determined by paper-disc agar-diffusion method. Minimum inhibitory concentration ( MIC) and Minimum bactericidal concentration ( MBC ) was determined by culture medium dilution methodand agar medium plate method, respectively. Antibacterial effect was compared between Shenju lotion and city sale of the gynecological lotion. Results Inhibitory effects of Shenju lotion on 5 pathogenic strains were significantly better than that of city sale of the gynecological lotion at the same concentrations (P<0. 05). MIC of Shenju lotion on Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis and Candida albicans was 33. 75, 67. 5, 67. 5, 67. 5 and 33. 75 mg ·mL-1 , respectively. MBC of Shenju lotion on Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis and Candida albicans was 33. 75, 67. 5, 67. 5, 135 and 33. 75 mg ·mL-1 , respectively. Conclusion Shenju lotion has obvious bacteriostasis and sterilization effect.
