Abstract

As a leading cause of bacterial-derived gastroenteritis worldwide, Campylobacter has a significant impact on human health. In the developed world, most campylobacteriosis cases are attributed to the consumption of undercooked, contaminated poultry; however, it has been shown that Campylobacter can be transmitted to humans through contaminated water and other types of food, including beef and milk. As such, high-resolution microbial source-tracking is essential for health department officials to determine the source(s) of Campylobacter outbreaks. For these reasons, this protocol provides the techniques needed for isolation of Campylobacter from agricultural and environmental sources, as well as human clinical specimens. Additionally, we describe a simple method for preparing high-quality genomic DNA that can be used for whole-genome sequencing and downstream bioinformatics analyses of Campylobacter genotypes. © 2018 by John Wiley & Sons, Inc.

环境弯曲杆菌的分离与全基因组测序
弯曲杆菌是世界范围内引起细菌性胃肠炎的主要原因,对人类健康有重大影响。在发达国家,大多数弯曲杆菌病病例归因于食用未煮熟、受污染的家禽;然而,已经证明弯曲杆菌可以通过受污染的水和其他类型的食物(包括牛肉和牛奶)传播给人类。因此,高分辨率的微生物来源跟踪对于卫生部门官员确定弯曲杆菌爆发的来源至关重要。由于这些原因,本方案提供了从农业和环境来源以及人类临床标本中分离弯曲杆菌所需的技术。此外,我们描述了一种制备高质量基因组DNA的简单方法,可用于弯曲杆菌基因型的全基因组测序和下游生物信息学分析。©2018 by John Wiley &儿子,Inc。

期刊介绍: Current Protocols in Microbiology provides detailed, step-by-step instructions for analyzing bacteria, animal and plant viruses, fungi, protozoans and other microbes. It offers updated coverage of emerging technologies and concepts, such as biofilms, quorum sensing and quantitative PCR, as well as proteomic and genomic methods. It is the first comprehensive source of high-quality microbiology protocols that reflects and incorporates the new mandates and capabilities of this robust and rapidly evolving discipline.
