标准范围

本文件规定了生成和分析从食物链获得的细菌全基因组测序(WGS)数据的最低要求。这个过程可以包括以下几个阶段:a) 细菌培养物的处理;b) 无菌基因组DNA分离;c) 库制备、测序和评估原始DNA序列读取质量和存储;d) 用于确定遗传相关性、遗传内容和预测表型的生物信息学分析,以及生物信息学管道验证;e) 元数据捕获和序列存储库沉积;f) 验证端到端WGS工作流(适合预期应用的目的)。本文件适用于从以下来源分离的细菌:—?供人类消费的产品;—?用于动物饲料的产品;—?食品和饲料处理和生产区域的环境样本;—?初级生产阶段的样品。

This document specifies the minimum requirements for generating and analysing whole genome sequencing (WGS) data of bacteria obtained from the food chain. This process can include the following stages:a) handling of bacterial cultures;b) axenic genomic DNA isolation;c) library preparation, sequencing, and assessment of raw DNA sequence read quality and storage;d) bioinformatics analysis for determining genetic relatedness, genetic content and predicting phenotype, and bioinformatics pipeline validation;e) metadata capture and sequence repository deposition;f) validation of the end-to-end WGS workflow (fit for purpose for intended application).This document is applicable to bacteria isolated from:—    products intended for human consumption;—    products intended for animal feed;—    environmental samples from food and feed handling and production areas;—    samples from the primary production stage.
