目的

探讨两面神菌致椎体感染的临床特征、诊断难点及抗菌治疗策略,为罕见菌椎体感染提供诊疗依据。

方法

回顾性分析2024年12月11日山东第一医科大学附属省立医院收治的1例两面神菌致椎体感染病例的诊疗经过,并检索知网、万方和Pubmed数据库截至2025年4月29日的两面神菌感染的文献,探讨两面神菌感染的临床特征及抗感染治疗方案。

结果

患者为15岁男性,无基础疾病,以胸部、腰部为主要表现,C-反应蛋白83.32 mg/L、人血清淀粉样蛋白A 348.26 mg/L、降钙素原0.31 ng/ml、白细胞介素-6 99.96 pg/ml、红细胞沉降率48.00 mm/h,计算机断层扫描和磁共振成像示T5椎体异常;经骨组织宏基因组二代测序(mNGS)明确两面神菌感染,予以利奈唑胺(600 mg/12 h)联合阿米卡星(400 mg、1次/d)抗感染治疗有效,出院半年后随访患者情况良好。

结论

两面神菌致椎体感染较为罕见,mNGS可辅助明确病原微生物,诊断明确后应及时应用敏感、骨组织穿透性良好的抗菌药物进行治疗。

Objective

To investigate the clinical characteristics, diagnostic challenges and antimicrobial therapeutic strategies of vertebral infection caused by Janibacter terrae, so as to provide evidence for the diagnosis and management of rare bacterial vertebral infections.

Methods

The clinical data of one adolescent patient with Janibacter-induced vertebral infection who was admitted to Shandong Provincial Hospital Affiliated to Shandong First Medical University on December 11st, 2024 were analyzed, retrospectively. Relevant literature on Janibacter terrae infections published from database establishment to April 29th, 2025 was retrieved from CNKI, Wanfang and PubMed databases to summarize the clinical manifestations and anti-infection regimens of Janibacter terrae infection.

Results

The 15-year-old male patient had no underlying diseases, and the chief complaint was chest and waist pain. Laboratory tests revealed elevated inflammatory biomarkers, C-reactive protein: 83.32 mg/L, serum amyloid A: 348.26 mg/L, procalcitonin: 0.31 ng/ml, interleukin-6: 99.96 pg/ml and erythrocyte sedimentation rate: 48.00 mm/h. Computed tomography (CT) and magnetic resonance imaging (MRI) showed abnormal lesions at the T5 vertebral body. Pathogen identification of Janibacter terrae was confirmed via metagenomic next-generation sequencing (mNGS) of bone tissue. Combined antimicrobial therapy with linezolid (600 mg every 12 hours) plus amikacin (400 mg once daily) achieved favorable therapeutic efficacy. The patient recovered well during the half-year follow-up.

Conclusions

Vertebral infection induced by Janibacter terrae is rare. mNGS facilitates rapid etiological confirmation. Timely administration of susceptible antibiotics with excellent bone tissue penetration is recommended once definite diagnosis is confirmed.
