中间链球菌（Streptococcus intermedius）是咽峡炎链球菌（Streptococcus anginosus）细菌组的成员。中间链球菌是口咽部、泌尿生殖道和胃肠道正常植物群的一部分;然而，已知它们可引起各种化脓性感染，包括脑膜炎、心内膜炎和脓肿，甚至在免疫功能正常的患者中也是如此。特别是，中间链球菌与肝和脑脓肿的发生有关。已有多例S.中间型肝脓肿伴活动性牙周感染。然而，据我们所知，还没有一例例行牙科手术后的病例。事实上，一般来说，牙科手术继发性肝脓肿的发生非常罕见，文献中只有少数病例报告描述了与任何病原体相关的情况。我们提出了一个罕见的情况下，S。牙齿清洁后出现中间菌血症和肝脓肿。这个病例进一步强调，即使是常规的牙科手术也会使患者面临菌血症和肝衰竭的风险。因此，临床医生必须确保进行详细的病史和仔细的检查。及时诊断化脓性肝脓肿是至关重要的，因为如果不及时治疗，它们通常是致命的。
Streptococcus intermedius is a member of the Streptococcus anginosus group of bacteria. This group is part of the normal flora of the oropharynx, genitourinary, and gastrointestinal tracts; however, they have been known to cause a variety of purulent infections includingmeningitis,endocarditis,andabscesses,eveninimmunocompetenthosts.Inparticular, S.intermedius hasbeenassociated with the development of liver and brain abscesses. There have been several case reports of S. intermedius liver abscesses with active periodontal infection. To our knowledge, however, there has not been a case following a routine dental procedure. In fact, the development of liver abscesses secondary to dental procedures is very rare in general, and there are only a few case reports in the literature describing this in relation to any pathogen. We present a rare case of S. intermedius bacteremia and liver abscess following a dental cleaning. This case serves to further emphasize that even routine dental procedures can place a patient at risk of the development of bacteremia and liver abscesses. For this reason, the clinician must be sure to perform a detailed history and careful examination. Timely diagnosis of pyogenic liver abscesses is vital, as they are typically fatal if left untreated.
