中文摘要:

      单核细胞增多性李斯特菌(Listeriamonocytogenes, LM)简称单增李斯特菌,是引起人和动物李斯特菌病的重要食源性病原菌, 具有较高的病死率, 严重危害人类公共卫生安全和畜牧业发展。快速准确地对LM鉴定和溯源, 对有效控制李斯特菌病的暴发和蔓延发挥重要作用。建立高效快捷的分型方法是LM溯源的关键。目前LM分型方法主要分为表型分型和分子分型, 每种分型方法各有优劣, 适用不同的流行病学调查。本文综述了LM分型方法的研究进展, 以期为开展LM的暴发确认和溯源检测方法的选择提供参考依据。

英文摘要:

      Listeria monocytogenes (LM) is described as an important foodborne pathogen that can cause humanand animals listeriosis, with the characteristics of high mortality. LM is seriously threatens the development of animal husbandry, human health and safety. It plays an important role in effectively controlling the foodborne disease outbreak and spread of listeriosis by rapid and accurate identification of LM pollution sources. Simple and efficient tracing techniques and typing methods are key to trace the source of LM. Currently, typing methods of LM include phenotypic typing and molecular typing. These typing methods have their own advantages and limitations, and have different applications on different epidemiological investigating. This paper reviewed the research progress of LM typing, in order to provide reference for the outbreak confirmation of LM and the selection of traceability detection methods.
