Abstract

Abstract: Foodborne pathogenic bacteria are the major risk of food safety, causing great harm to human health. Thus, it is urgent to research and establish an accurate and effective detection method for foodborne pathogenic bacteria. With the rapid development of single-molecule techniques, digital PCR has been widely used in detection of foodborne pathogenic bacteria due to their outstanding advantages, such as high sensitivity, high stability and low reagent consumption. This review mainly summarized the basic principles and research progress of digital PCR. The applications of digital PCR technology in detection of Escherichia coli, Salmonella, Staphylococcus aureus, Campylobacter jejuni, Shigella, Cronobacter, Vibrio parahaemolyticus, Listeria monocytogenes and Bacillus cereus were also discussed, which would provide further insight into the detection of foodborne pathogenic bacteria.

Key words: detection of foodborne pathogenic bacteria, digital PCR, droplet digital PCR

摘要： 食源性致病菌是食品安全的重大隐患，对人类健康造成极大危害，因此亟待研究和建立精准有效的食源性致病菌检测方法。随着单分子检测技术的快速发展，数字PCR技术因其具有超高的灵敏度、稳定性和低试剂消耗等优点而被广泛应用于食源性致病菌的检测。主要介绍了数字PCR的基本原理及其研究进展，深入探讨了其在检测大肠杆菌（Escherichia coli）、沙门氏菌（Salmonella）、金黄色葡萄球菌（Staphylococcus aureus）、空肠弯曲菌（Campylobacter jejuni）、志贺氏菌（Shigella）、克罗诺杆菌（Cronobacter）、副溶血性弧菌（Vibrio parahaemolyticus）、单核细胞增生李斯特氏菌（Listeria monocytogenes）和蜡状芽孢杆菌（Bacillus cereus）中的应用，为今后该技术在食源性致病菌检测中的研究与应用提供一定的技术性参考。
