one of the most common bacteria associated with failed RCT or persistent endodontic infections
- Facultative anaerobe (adapts aerobic or anaerobic)

Q
what does a virulence factor mean and what are some examples
A
make something more harmful
- endotoxins
- adhesins
- collagenases
- hyaluronidase
- immune evasion
