Since listeriosis, caused by Listeria monocytogenes, is one of the important concerns of public health in Europe related to foodborne zoonoses, an efficient protocol for isolate typing is necessary when performing epidemiological studies. Three standardized PFGE protocols available for L. monocytogenes were briefly reviewed. Since observing a poor-quality of ApaI pulsotypes in our laboratory, enzymes from three different manufacturers were compared. The obtained pulsotypes showed that restriction digestion with ApaI from New England BioLabs should be complemented with a subsequent overnight incubation of PFGE plugs in TE buffer for better performance.
由于李斯特菌病是由单增李斯特菌引起的,是欧洲与食源性病原体相关的重要公共卫生问题之一,因此在进行流行病学研究时,需要有效的分离株分型方法。本文简要综述了三种用于单增李斯特菌的标准化 PFGE 方案。由于在本实验室观察到 ApaI 脉冲类型质量较差,因此比较了来自三个不同制造商的酶。所得的脉冲类型表明,用来自 New England BioLabs 的 ApaI 进行限制消化后,应在 TE 缓冲液中过夜孵育 PFGE 插头,以获得更好的性能。
