Genomic insights into Enterococcus faecalis implicated in endodontic infections: resistance, virulence, and genetic variability.

Endodontic infections, often involving multispecies bacterial communities, present significant challenges in treatment due to their complex pathogenic mechanisms and resistance to conventional therapies. Enterococcus faecalis is a facultative anaerobic gram-positive bacterium that has been frequently recovered from secondary or persistent endodontic infections. This study investigates the population structure, resistome, mobilome, and virulome of E.
