Abstract: |
目的 采用国际标准化的脉冲场凝胶电泳(PFGE)分析方法对单核细胞增生李斯特菌(Lm)进行基因分型,初步建立中国Lm的基因分型数据库。方法 按照标准化的Lm-PFGE方法对来自国内8个省市、多种食品来源的118株Lm进行了PFGE分型。结果 118株Lm分成了39种带型,其中GX6A160004型有37株菌,占分析菌株的31。36%,是主要型别。结论 初步建立了中国单核细胞增生李斯特菌用于网络监测分析(PulseNet China)的基础数据库,发现同型菌株在全国多个地区广泛存在。 |

Objective To analyse the molecular types of Listeria(L.)monocytogenes,and to construct the standard China L. monocytogenes pulsed-field gel electrophoresis(PFGE) subtyping database,using the international standardized L.monocytogenes-PFGE protocol. Methods 118 L.monocytogenes strains isolated from 8 provinces or municipalities of China were subtyped according to L.monocytogenes-PFGE protocol. Results 118 strains of L. monocytogenes were divided into 39 subtypes. In the 39 subtypes, 37 strains(31.36)were GX6A160004 pattern, showing it was the predominant Lm subtype in China. Conclusion Data from molecular typing suggested that the predominant Lm strains were distributed in different regions of China. PulseNet China-Lm database was constructed which was valuable for the molecular subtyping-based surveillance of L.monocytogenes. |
