Abstract

This study was conducted on the fecal Enterococcus faecalis bacteria in 40 samples isolated from people with root canal infections. The samples include 20 samples from patients with primary infections of the root canal and 20 samples from those with secondary root canal infections (re-treatment) from different age groups (20-55 years). The collected isolates were diagnosed by vascular and biochemical tests and the Vitek2 diagnostic technique. Thirty isolated samples belonging to E. faecalis bacteria. 13 samples of E. faecalis were identified by biochemical tests, and 17 were diagnosed with the Vitek2 system. Antibiotic resistance of 30 diagnosed E. faecalis isolates using 14 antibiotics showed their resistance to all the antibiotics. Some strains were multi-resistant to some antibiotics, and all isolates showed 100% resistance to five antibiotics viz. Streptosporin, Clindomycin, Trimethoprine, Cephalothin, Tetracyclin. In virulence factors tests, the diagnosed isolates showed their ability to produce virulence factors in 22 isolates with 37.3% protease-producing isolates.
