苏黎世放线菌(Actinomyces turicensis)是一种单细胞原核微生物，是健康人群口腔中的主要菌群，该菌若进入其他部位引起感染，可导致放线菌病。本文介绍了1例苏黎世放线菌引起的腹膜透析导管隧道感染病例，患者先后经过美罗培南、头孢噻肟抗感染治疗后，病变好转出院。本文通过介绍苏黎世放线菌感染的临床特点、实验室检测及治疗方法，从而帮助临床医师进一步熟悉该类疾病的诊断和治疗，并强调临床和实验室应保持及时、有效的临床沟通，才能达到早诊断、早治疗的目的。

Actinomyces turicensis is a single-cell prokaryotic microorganism, which is the main oral flora of healthy people. If it enters other parts to cause infection, it may cause actinomycosis. This article introduced a case of tunnel infection of peritoneal dialysis catheter caused by Actinomyces turicensis. The patient was treated with meropenem and cefotaxime, and the disease was improved and the patient was discharged. By introducing the clinical characteristics, laboratory detection and treatment methods of Actinomyces turicensis infection, this study helps clinicians to become more familiar with the diagnosis and treatment of this kind of disease, and emphasizes that the clinical and laboratory should maintain timely and effective clinical communication to achieve early diagnosis and treatment.
