Virulence Genes, Antibiotic Resistance and Capsule Locus Polymorphisms in<i>Enterococcus faecalis</i>isolated from Canals of Root-Filled Teeth with Periapical Lesions

Abstract

isolates from canals of root-filled teeth were identified, and phenotypic and genotypic characteristics were investigated. No resistance to vancomycin and gentamicin was noted, and most isolates (91%) were susceptible to ampicillin. Biofilm formation was detected in 73% of the isolates and may be considered as the most important virulence factor involved in the pathogenesis of these isolates.
