We herein present the case of a 43-year-old male diabetic patient who presented with an aggressive form of infective endocarditis involving the tricuspid, mitral and aortic valves following a gluteal abscess due to infection with Staphylococcus lugdunensis. This coagulase-negative organism which is generally considered a component of the normal flora of the skin has however recently emerged as an unusually virulent pathogen responsible for both nosocomial and community-acquired infections. The case demonstrates the importance of paying utmost attention and ensuring a logical conclusion to the identification of persistent coagulase-negative blood cultures. In addition, it also shows the importance of early identification of this organism and aggressive antibiotic administration to avert endocarditis because of the unusual virulence of the organism. Staphylococcus lugdunensis is rarely a clinical specimen contaminant, and its isolation warrants further investigation and concerted treatment.
我们在此报告一例43岁男性糖尿病患者的病例，该患者因感染路邓葡萄球菌导致臀肌脓肿后，出现了一种侵袭性感染性心内膜炎，累及三尖瓣、二尖瓣和主动脉瓣。这种凝固酶阴性的微生物通常被认为是皮肤正常菌群的一部分，但最近已成为一种异常毒力的病原体，可导致医院获得性感染和社区获得性感染。该病例表明，对于持续的凝固酶阴性血培养结果的鉴定，必须给予高度关注并确保得出合理结论。此外，由于该微生物具有异常的毒力，它还显示了早期识别该微生物并积极给予抗生素治疗以避免心内膜炎的重要性。路邓葡萄球菌很少是临床标本的污染物，其分离需要进一步调查和协同治疗。
