Intracranial infections caused by multidrug-resistant Gram-negative bacterium have led to considerable mortality due to extremely limited treatment options. Herein, we firstly reported a clinical carbapenem-resistant isolate coharboring and from a patient with post-craniotomy meningitis. The carbapenem-resistant strain CNEC001 belonging to Sequence Type 410 was only susceptible to amikacin and tigecycline, both of which have poor penetration through the blood-brain barrier (BBB). The gene was expressed on a 135,794 bp IncY plasmid. The gene was located on a genomic island region of an IncX3-type plasmid pNDM5-CNEC001. Based on the characteristics of the strain, we presented the successful treatment protocol of intravenous (IV) tigecycline and amikacin combined with intrathecal (ITH) amikacin in this study. Intracranial infection caused by coharboring and is rare and fatal. Continuous surveillance and infection control measures for such strain need critical attention in clinical settings.
耐多药革兰氏阴性菌引起的颅内感染,由于治疗选择极其有限,已导致相当高的死亡率。在此,我们首次报告了一例来自开颅术后脑膜炎患者的临床耐碳青霉烯分离株,该分离株同时携带[未提及的两种病菌名称]。属于序列型410的耐碳青霉烯菌株CNEC001仅对阿米卡星和替加环素敏感,而这两种药物通过血脑屏障(BBB)的穿透性都很差。[未提及的第一种病菌名称]基因在一个135,794 bp的IncY质粒上表达。[未提及的第二种病菌名称]基因位于IncX3型质粒pNDM5 - CNEC001的一个基因组岛区域。基于该菌株的特性,我们在本研究中提出了静脉注射(IV)替加环素和阿米卡星联合鞘内注射(ITH)阿米卡星的成功治疗方案。由[未提及的两种病菌名称]共同携带引起的颅内感染罕见且致命。在临床环境中,对此类菌株的持续监测和感染控制措施需要引起高度重视。
