体检和性罪错人群宫颈中解脲脲原体的检测

目的了解解脲脲原体(Uu)在体检人群和性罪错人群的宫颈检出情况及生物分群分型。方法用支原体液体选择培养基筛查妇科体检人群和性罪错人群,对阳性标本再用PCR法进行生物分群分型。结果性罪错人群共筛查了卖淫妇女98例,体检人群共筛查了体检妇女164例。性罪错组中Uu液体培养阳性89例(90.8%),其中生物1群64例(71.9%),1+2群7例(7.9%),2群18例(20.2%);71例生物1群阳性的标本中,以血清1、3、6、14型两个或两个以上的同时感染为混合感染,以血清1、3、6、14型的单独感染为单纯感染。性罪错组中混合感染17例(23.9%),单纯感染54例(76.1%);54例单纯感染中血清1型17例(31.5%),3型22例(40.7%),6型15例(27.8%)。体检人群组中Uu液体培养阳性104例(63.4%),其中生物1群97例(93.3%),2群7例(6.7%);97例生物1群阳性的标本中,混合感染11例(11.3%),单纯感染86例(88.7%),86例单纯感染中血清1型22例(25.6%),3型37例(43.0%),6型27例(31.4%)。结论Uu在性罪错人群中的检出率高于体检人群(P<0.01),在Uu培养阳性的标本中,生物2群的检出率性罪错人群高于体检人群(P<0.01),在Uu生物1群阳性的标本中,混合感染的检出率性罪错人群高于体检人群(P<0.05),而生物1群中各血清型的单纯感染两组间没有统计学差异。

The Detection of Ureaplasma urealyticum in Cervix of Gynecologic Check-up Population and Female Sex Workers and Its Biovars and Serotypes

Objective To investigate Ureaplasma urealyticum in cervical specimens of gynecologic check-up population and female sex workers(FSW)and its biovars and serotypes.Methods The gynecologic check-up patients and female sex workers were screened using Uu liquid selective medium.The positive cases were then divided into biovars and serotypes by the means of PCR.Results Ninety-eight FSW and164gyne-cologic check-up patients were investigated.In the FSW group,89cases(90.8%)were positive in culture,in-cluding biovar164cases(71.9%),biovar1+27cases(7.9%),biovar218cases(20.2%).In71biovar1positive cases,biovar1+2and co-infection of serotypes of biovar1were defined as mixed infection.Infection with single serotype of biovar1was defined as simple infection.So in71biovar1positive cases of FSW group,there were17mixed infections(23.9%)and54simple infections(76.1%).Simple infections were then subdivided into serotypes,including serotype117cases(31.5%),serotype322cases(40.7%),and serotype615cases(27.8%).In gynecologic check-up group,104cases(63.4%)were culture positive,in-cluding biovar197cases(93.3%),biovar27cases(6.7%).In97biovar1positive cases,there were11mixed infections(11.3%)and86simple infections(88.7%).In86simple infections,there were serotype122cases(25.6%),serotype337cases(43.0%),and serotype627cases(31.4%).Conclusions The posi-tive rate of Uu in FSW is higher than that of gynecologic check-up population(P<0.01).The positive rate of Uu biovar2in FSW is higher than that of control group(P<0.01).The mixed infection in sex workers is higher than that of gynecologic check-up population(P<0.05).There is no statistic difference in simple in-fection caused by serotypes of biovar1between the two group.
