肠球菌发生在涉及口腔的机会性感染中。这项研究鉴定了29例接受Ca(OH)(2)敷料治疗的牙髓感染的肠球菌种类。对分离的29株肠球菌进行了体外药敏试验。粪肠球菌26株，屎肠球菌3株。体外药敏试验显示，肠球菌对青霉素、氨苄西林、克林霉素、甲硝唑、四环素耐药，对红霉素、万古霉素敏感。由于对抗菌药的敏感性较低，肠球菌可能会被选择在接受标准根管治疗的根管中，并极大地导致根管治疗失败。
Enterococci are occurring in opportunistic infections involving the oral cavity. This study has identified enterococcal species in 29 endodontic infections undergoing treatment with Ca (OH)(2) dressings. The in vitro antimicrobial susceptibility of 29 isolated enterococcal strains was determined. Enterococcus faecalis was speciated for 26 isolates and Enterococcus faecium for three isolates. In vitro antimicrobial susceptibility testing revealed enterococcal isolates resistant to benzylpenicillin, ampicillin, clindamycin, metronidazole and tetracycline but sensitive to erythromycin and vancomycin. Due to low sensitivity to antimicrobial agents, enterococci may be selected in root canals undergoing standard endodontic treatment and significantly contribute to endodontic treatment failures.
