大蒜液对空肠弯曲杆菌的抑菌作用研究

Study on antibacterial activity of garlic solution against Campylobacter jejuni

目的研究大蒜提取液对空肠弯曲杆菌的抑菌作用,为进一步利用大蒜资源提供理论依据。方法直接捣碎大蒜提取大蒜液,用琼脂纸片扩散法(K-B纸片法)和肉汤稀释法检测大蒜液对空肠弯曲杆菌的抑菌作用。结果大蒜液对空肠弯曲杆菌的最小抑菌浓度(MIC)为40%,其抑菌活性与浓度呈正相关。结论大蒜液对空肠弯曲杆菌有较强的抑菌作用。

Objective To explore the antibacterial activity of garlic solution against Campylobacter jejuni,and to provide theoriti-cal basis for further utilization of garlic.Methods Mashed garlic and extracted garlic solution.Antimicrobial susceptibility was de-termined by usig K-B disk diffusion test and broth dilution method.Results The minimal inhibitory concentration（MIC）of garlic solution against campylobacter jejuni was 40%.It showed positive correlation between bacteriostatic effect and concentration of gar-lic solution.Conclusion Garlic solution has strong bacteriostasis function to campylobacter jejuni.
