摘要 〔目的〕通过对食品中β-溶血性链球菌检验技术的研究,选择操作性强、证实方法简便准确、检测周期较短的检验技术,为今后修订国家标准,向国际标准化靠拢提供有利依据。〔方法〕利用胰蛋白胨大豆肉汤TSB增菌液、哥伦比亚CNA血琼脂平板厌氧培养、API20STREP生化鉴定试剂盒及常规生化鉴定检测食品中的β-溶血性链球菌。〔结果〕试验结果显示,本方法适用于β-溶血性链球菌的培养、分离与鉴定。胰蛋白胨大豆肉汤TSB增菌液、哥伦比亚CNA血琼脂平板的增菌、分离效果优于GB/T4789.11-2003中的葡萄糖肉浸液肉汤和普通血琼脂。〔结论〕API 20 STREP快速鉴定系统更是为简化操作程序,缩短检测周期提供有效方法。
