戈登链球菌所致感染性心内膜炎1例

Infective endocarditis due to Streptococcus gordonii:a case report

感染性心内膜炎(infective endocarditis, IE)是一种少见但危及生命的疾病。侵入性口腔操作(invasive dental treatments,IDT)可产生暂时性菌血症,因此被认为是IE的潜在危险因素。当患者在IDT后出现不明原因发热时,临床医师需高度警惕患者发生IE的可能性。戈登链球菌是牙周环境的常见定植菌之一。本文报道了1例拔牙后由戈登链球菌引起IE病例,该病例提示IE与IDT之间存在重要联系。

Infective endocarditis(IE) is a rare but life-threatening disease. Invasive dental treatment(IDT) can produce temporary bacteremia, so they are considered as potential risk factors for IE. The physicians should pay attention to the possibility of IE, when patients have fever of unknown origin after IDT. Streptococcus gordonii is one of the common colonization bacteria in periodontal environment. A case of infective endocarditis caused by Streptococcus gordon after tooth extraction was reported. This case suggests an important link between IE and IDT.
