Data from "Extracellular DNA (eDNA). A Major Ubiquitous Element of the Bacterial Biofilm Architecture" (doi.org/10.3390/ijms22169100)

This review was generated in the context of a broader systematic survey aimed at gathering all the information currently available in the literature on extracellular DNA, with special reference to its physiology and functions in bacterial biofilms. The bibliographic research was primarily conducted using Web of Science and then extended to PubMed and Google Scholar. The initial broad query adopted in Web of Science was as follows: “extracellular DNA” (Topic) AND “Bacteria” (Topic) NOT “cancer” (Topic). An alert was set, and the search results were regularly updated until May 5, 2021. Overall, 2,613 article entries were obtained from this broad search. Experimental articles were thoroughly screened based on title and abstract. The content of review articles was examined, and their relevant citations were assessed and, where appropriate, included. The present systematic review was based on the articles selected as relevant to the category “Structural role of eDNA in the biofilm architecture”.本综述依托一项系统性综合调研撰写而成，该调研旨在全面收录当前文献中关于细胞外DNA（extracellular DNA）的所有公开研究资料，重点关注其在细菌生物被膜（bacterial biofilms）中的生理学特性与功能。本次文献检索工作主要以Web of Science为首要数据库，随后拓展至PubMed与Google Scholar。Web of Science中初始的广谱检索式为："extracellular DNA"（主题字段）AND "Bacteria"（主题字段）NOT "cancer"（主题字段）。随后设置了检索提醒，检索结果持续更新至2021年5月5日。本次广谱检索共获取2613条文献条目。研究人员依据文献标题与摘要对实验类文章开展严格筛选；同时研读综述类文章的内容，评估其相关参考文献并酌情纳入符合要求的文献。本项系统性综述的筛选依据为：选取与"eDNA在生物被膜结构中的作用"这一主题相关的文献。
