单增李斯特菌生物膜形成调控机制的研究进展

Advances on the mechanisms regulating the formation of the biofilm of Listeria monocytogenes

摘要:

单增李斯特菌是一种重要的食源性病原菌。单增李斯特菌的分布和存活与其形成生物膜的能力有关，生物膜对逆性环境有抵抗力，细菌会从生物膜中分离导致食品持续性的污染。生物膜的形成、成熟和结构取决于多种外部和内部因素，并且多种调控机制起着重要作用。文中旨在阐述单增李斯特菌生物膜形成过程中的调控机制 (包括胞内作用、胞间作用和种间作用)，以控制食品加工环境中致病性生物膜的形成，从而为食品安全提供新的干预策略。

Abstract:

Listeria monocytogenes is an important food-borne pathogen. The distribution and survival of L. monocytogenes are related to its ability to form biofilms. Biofilms are resistant to adverse environments, and bacteria separated from the biofilms may lead to persistent food contaminations. The formation, maturation and structure of biofilms depend on a variety of external and internal factors, among which a variety of regulatory mechanisms play important roles. This review summarizes the regulatory mechanisms (including intracellular, intercellular and interspecific interactions) involved in the biofilm formation of L. monocytogenes in order to control the biofilm formation in food processing environments, thus providing new intervention strategy for food safety.
