过去,肠球菌由于携带抗生素抗性基因或其他毒力因子基因,常被视为机会致病菌。然而,近年来的研究表明,特定的肠球菌,如蒙氏肠球菌,可能具有对动物和人类有益的特性。蒙氏肠球菌能产生肠球菌素(enterocins,一种抗菌蛋白质类物质,也属于后生元 postbiotics),可用于预防乳腺炎。因此,深入研究蒙氏肠球菌,挖掘其潜在价值,对保障动物和人类健康意义重大。
02. 鉴定技术升级:推荐采用基因测序(如16S rRNA、recA基因分析)和基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)等精准鉴定技术,取代传统生化方法,提升检测灵敏度。 03. 溯源管理:要求企业建立生产环境微生物数据库,对检出的菌株进行分子分型 ...
