摘　　要：目的检测某品牌饮用天然矿泉水样品中是否含有粪链球菌,并对出现的疑似菌落进行分析。方法按照GB 8538.56-2016《食品安全国家标准饮用天然矿泉水检验方法》中粪链球菌的检测方法对样品进行检测,对疑似菌落进行确证性实验,并通过VITEK2COMPACT全自动微生物鉴定系统对疑似菌进行鉴定。结果滤膜上出现典型红色菌落,经确证性实验确认为非粪链球菌;经VITEK2COMPACT鉴定,该菌为粘质沙雷氏菌。结论样品中的疑似菌落非粪链球菌而是粘质沙雷菌。Objective To detect the presence of Enterococcus faecalis in a natural mineral water sample and analyze the suspected bacterial colonies.Methods The samples were tested in accordance with the test method specified in GB 8538-2016 National food safety standard-Inspection of natural mineral water for drinking,and the suspected bacterial colonies were confirmed by VITEK 2 COMPACT automatic microbial identification system.Results The typical red colony appeared on the membrane,which was confirmed as non-streptococcus faecalis by confirmative test.VITEK 2 COMPACT identified the bacteria as Serratia marcescens.Conclusion The suspected colony of Enterococcus faecalis in the samples is not Enterococcus faecalis but Serratia marcescens.
