解脲脲支原体基因型的检测及其意义

目的 了解解脲脲支原体(Uu)基因分型情况,探讨其基因分型临床意义.方法 选择2010年8月-2011年2月在绍兴县中心医院门诊380例女性生殖道感染患者,以及同期无自觉症状的240例健康体检者,分别收集宫颈拭子标本,运用荧光定量PCR技术(RT-PCR)筛选出Uu阳性的初诊样本,设计分型引物,运用反向点杂交技术进行基因分型检测.结果 患者组Uu阳性270例,阳性率为71.05％,健康组阳性104例,阳性率为43.33％；患者组单纯U.parvum群感染率为63.77％,低于健康组的78.79％,差异有统计学意义(P＜0.05)；健康组中解脲脲支原体parvum群以其中的1、3、6基因型的单型别为主；患者组中Uu两群感染率较健康组高,差异有统计学意义(P＜0.05);患者组U.urealyticum群与1型的多型别感染率高于健康组,差异有统计学意义(P＜0.05).结论 U.parvum群,尤其是其中的1、3、6型别是正常人群携带的可能性较大,U.urealyticum则有可能和1型起协同作用或独自导致疾病.

Detection and identification of genotyping of Ureaplasma urealyticum and its clinical significance

OBJECTIVE To investigate the distribution of genotypes of Ureaplasma urealyticum(Uu)in female genitourinary tract and explore its clinical significance. METHODS A total of 270 genital tract infected women who were admitted to hospital from Aug 2010 to Feb 2011 and 240 normal health examination women were chosen.Cervical secretions were collected and DNA was extracted for examining.Primers for typing were designed and detect genotype of Ureaplasma urealyticum by Reverse dot blot hybridization(RDB).
