巴斯德葡萄球菌引起导管相关血流感染1例

Catheter-related bloodstream infection caused by Staphylococcus pasteuri: one case report

摘要:

1例患者因“脓毒血症、慢性肾病、2型糖尿病、休克、脑梗死”入院,临床抽取血标本进行相关检查,导管血和静脉血需氧和厌氧培养均报阳,通过VITEK MS鉴定病原菌是巴斯德葡萄球菌,确定为巴斯德葡萄球菌引起的导管相关血流感染。临床经验性使用哌拉西林抗感染治疗无效后,最终根据体外药敏试验改用万古霉素治疗,并拔除血管导管病情好转。巴斯德葡萄球菌目前在国内尚未有相关的病例报道,尽早明确病原学诊断和根据药敏试验结果调整治疗方案,对于该病例的有效治疗非常重要。

Abstract:

One patient was admitted to a hospital due to "sepsis, chronic kidney disease, type 2 diabetes, shock, and cerebral infarction". Patient’s blood specimen was taken for clinical examination. Aerobic and anaerobic culture results of catheter blood and venous blood were both positive. The pathogen was identified as Staphylococcus pasteuri by VITEK MS, and the patient was diagnosed as catheter-related bloodstream infection caused by Staphylococcus pasteuri. Clinical empirical use of piperacillin for anti-infection treatment was ineffective, and vancomycin was eventually used for treatment based on in vitro antimicrobial susceptibility testing. Patient’s condition improved after removing the venous catheter. There are currently no reported cases of Staphylococcus pasteuri in China. Early identification of pathogen and adjustment of treatment plans based on antimicrobial susceptibility testing results are crucial for effective treatment of this case.
