Abstract

Background: Yokenella regensburgei is a gram-negative, opportunistic pathogen that is ubiquitous in natural environments. It commonly affects immunocompromised patients.

Methods: The patient was a 71-year-old female with skin and soft tissue wound caused by trauma. The surgical debridement and abscess drainage were performed by surgeons. The specie of infected organism was identified by the D2Mini semi-automated system and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF).

Results: The result of bacterium culture showed gram-negative bacillus was moist, grey-white, semitransparent, and regular shape. Then the D2Mini semi-automated system and MALDI-TOF revealed that the colonies are Y. regensburgei. According to the result for drug sensitivity, antibiotic therapy was switched to cefoperazone/sulbac-tam and levofloxacin.

Conclusions: Cooperation between clinical microbiology laboratories and surgeons is essential for the infected patient without typical symptoms. Agricultural activities and stab wounds may be related to Y. regensburgei infection.

一名免疫功能正常的患者感染了雷根斯堡尤肯菌。

背景：Yokenella regensburgei 是一种革兰氏阴性机会性病原体，在自然环境中无处不在。它通常影响免疫力低下的患者：患者是一名 71 岁的女性，因外伤造成皮肤和软组织伤口。外科医生为患者进行了手术清创和脓肿引流。采用 D2Mini 半自动系统和基质辅助激光解吸/电离飞行时间质谱（MALDI-TOF）对感染菌种进行鉴定：细菌培养结果显示，革兰氏阴性杆菌湿润、灰白色、半透明、形状规则。D2Mini 半自动系统和 MALDI-TOF 检测结果显示菌落为雷根斯堡酵母菌。根据药敏结果，抗生素治疗改为头孢哌酮/舒巴坦和左氧氟沙星：结论：对于无典型症状的感染者，临床微生物实验室和外科医生之间的合作至关重要。农业活动和刺伤可能与雷根斯堡酵母菌感染有关。
