PCR和培养法检测泌尿生殖道解脲支原体比较

目的 对聚合酶链反应（ＰＣＲ）和培养法检测泌尿生殖道解脲支原体（Ｕｕ）进行比较。方法 用上述二种方法同时检测１１６例患者的泌尿生殖道拭子。结果 ＰＣＲ检测阳性４６例,培养阳性４５例,培养阳性的４５例中ＰＣＲ阳性４２例。若以培养法为对照,ＰＣＲ敏感性为９３．３％,特异性为９４．４％。ＰＣＲ和增减法检测Ｕｕ的阳性率无显著差异（Ｐ〉０．０５）。结论 ＰＣＲ检测泌尿生殖道解脲支原体,敏感性高,特异性强,与

Comparison of polymerase chain reaction and culture method for assaying ureaplysma urealyticum in urogenital specimens

OBJECTIVE: A comparison study of polymerase chain reaction (PCR) and culture method were used to detect urogenital ureaplasma urealyticum. METHODS: Urogenital specimens from 116 patients were assayed in parallel by the two methods. RESULTS: 46 cases were positive by PCR, 42 cases positive by culture, and UuDNA were dedected in 42 cases of the 45 positive by culture. Compared with culture, the sensitivity and specificity of PCR were 93.3% and 94.4%, respectively. The positive rate of both methods were comparable (P > 0.05). CONCLUSIONS: The PCR technique to detect Uu is highly sensitive and specific. As for culture method, it takes the advantage of being relative simple and takes much less time to give results.
