| 摘 要： | 目的:分析和鉴定不同产地酸奶中乳酸菌对一些常用抗生素的敏感性,指导合理使用抗菌药物与合理使用乳酸菌发酵制品。方法:利用改良的MRS培养基从各地酸奶中分离获得乳酸菌,然后采用琼脂稀释法,对分离获得的18株保加利亚乳杆菌和28株嗜热链球菌对11种常用抗生素的药物敏感性进行检测和分析。结果:同一菌株对不同的抗生素具有不同的药物敏感性,不同菌株对同一种抗生素也显示出不同的敏感性。结论:乳酸菌对常用抗生素的多重耐药已成为普遍现象,不同来源的菌株表现出了不同的耐药性。

| Abstract: | Objective:To investigate the susceptibility of lactic acid bacteria(LAB)isolated from yoghurts for medical purpose to 11 antimicrobial agents.Methods:18 Lactobacillus bulgaricus and 28 Streptococcus thermophilus selected on modified MRS media from yoghurts were examined for antibiotic resistance by using the agar dilution method.Results:The same strain presented different sensitivity to different antibiotics,and different isolates also showed different resistance to the same antibiotic.Conclusions:Multidrug resistance was identified in most isolates and different resistance was seen in different isolates. |
