We developed a fluorescence in situ hybridization (FISH) method for the rapid detection of Proteus spp. in urine, using a novel peptide nucleic acid (PNA) probe. Testing on 137 urine samples from patients with urinary tract infections has shown specificity and sensitivity values of 98 % (95 % CI, 93.2-99.7) and 100 % (95 % CI, 80,8-100), respectively, when compared with CHROMagar Orientation medium. Results indicate that PNA-FISH is a reliable alternative to traditional culture methods and can reduce the diagnosis time to approximately 2 h.
我们开发了一种使用新型肽核酸 (PNA) 探针的荧光原位杂交 (FISH) 方法,用于快速检测尿液中的变形菌属。对 137 份尿路感染患者的尿液样本进行检测,与 CHROMagar Orientation 培养基相比,该方法的特异性和灵敏度分别为 98%(95%CI,93.2-99.7)和 100%(95%CI,80.8-100)。结果表明,PNA-FISH 是传统培养方法的可靠替代方法,可将诊断时间缩短至约 2 小时。
