肠球菌在海水中的消亡机制研究进展

Enterococcus decay in coastal waters: a review

摘要:

肠球菌作为近岸海域粪便污染的指示细菌和条件致病菌，在海水中的生长与消亡对水质监测以及公众健康具有重要影响。本文简述肠球菌在海水中的生理及分布特征，综述肠球菌在关键环境因子和生物因子影响下的消亡规律，并着重介绍肠球菌在细胞和分子水平的消亡机制与消亡动力学模型，同时对肠球菌的研究方向进行展望。通过构建肠球菌浓度预测模型，以期实现因公众亲海导致感染病原微生物风险的早期预警，对海水浴场管理提供有效的参考依据。

Abstract:

As a fecal bacterial indicator of seawater and an opportunistic bacterium, Enterococcus is used for water quality monitoring and closely related to the public health. In this paper, the physiological and distribution characteristics of Enterococcus in the seawater are described at first. Then, decay mechanism of Enterococcus was introduced under the impact of the key environmental factors and biological factors, and decay kinetics model of Enterococcus in cellular and molecular level are summarized. Finally, the research direction of Enterococcus in seawater is addressed. By establishing the Enterococcus concentration prediction model, early warning of the risk of pathogenic microorganism infection in bathing beaches and other recreational waters will be feasible.
