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”.
