普罗维登西亚雷氏杆菌(P.rettgeri)是一种普遍存在的生物体，但很少与人类疾病相关。我们报告从一名39岁男性患者的尿样中分离出雷特杰氏杆菌，该患者在严重头部损伤后接受了长时间的Foley导尿术。利用基质辅助激光解吸电离飞行时间质谱仪(MALDI-TOF)对该微生物进行了鉴定。雷氏假单胞菌是长期留置尿管患者中的一种新的病原体。它反映了它在留置导管表面形成生物膜的能力，以及作为可能的发病机制的病原体固有的尿素酶产生特性。
Providencia rettgeri (P. rettgeri) is an ubiquitous organism but is seldom associated with human disease. We report the isolation of P. rettgeri from the urine sample of a 39-year-old male patient on prolonged Foley's catheterisation following a severe head injury. Identification of this organism was done by Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF) based systems. P. rettgeri is an emerging pathogen among long term catheterised patients. It reflects its ability to form biofilm on the surface of the indwelling catheter as well as the inherent urease producing property of the pathogen in question as a possible mechanism of pathogenesis.
