摘要:  摘要:目的 比较选择性固体培养基与液体培养基检测男女不同类型生殖泌尿道标本中解脲脲原体(Uu)结果的差异,并观察Uu在固体培养基上的菌落形态学特征。方法 1 698例生殖泌尿道标本被分别接种于固体培养基和液体培养基中,比较不同类型标本中Uu的阳性率、2种培养基的阳性率以及菌落形态学的差异。结果 女性宫颈分泌物标本中Uu阳性率(49.9%)显著性高于男性精液和尿道分泌物标本(39.6%、19.2%,P均<0.05);液体培养法与固体培养法相比,女性宫颈分泌物标本Uu阳性率差异有统计学意义(P<0.05),而男性精液和尿道分泌物标本Uu阳性率之间差异无统计学意义(P>0.05);Uu菌落形态以海胆型为主(77.5%),其次是油煎蛋样(13.8%),空泡型、微小型、棒状和混合型较少见。结论 女性宫颈分泌物标本中Uu阳性率最高,男性尿道分泌物标本Uu阳性率最低。对于女性宫颈分泌物标本,2种方法检测Uu的结果差异较大;对于男性尿道分泌物标本,2种方法检测结果一致性较好。Uu在菌落形态学方面存在多种异质性。

Abstract: Objective The results of detecting Ureaplasma urealyticum(Uu) from different kinds of samples in the liquid medium and the selective solid medium were compared, and morphological characters of Uu colonies by the selective solid culture medium were observed. Methods The 1698 samples from urogenital tract were cultured in the liquid medium and the selective solid medium. The positive rates from the two assays and three kinds of samples were compared and analyzed. The colonies features of Uu were observed by the selective solid medium. Results The positive rate of Uu from female urogenital tract was significantly(49.9%)higher than that from semen(39.6%)and urethral discharge(19.2%)(P<0.05). There was significant difference of the positive rate from female urogenital tract between the liquid medium and the selective solid medium(P<0.05). However, there were no statistics significance of the positive rate from male urogenital tract between the two assays(P>0.05). The main colonies of Uu was typical echinus colony(77.5%), fried egg colony(13.8%), vesicle colony, tiny colony, coryneform colony and mixed colony. Conclusions The positive rate of Uu from female urogenital tract is higher than that from semen samples, and the positive rate from male urethral discharge is the lowest. The results of Uu from female specimens using two media are different obviously. There is a good consistency between the two ways about the male samples. Uu colonies have morphological heterogeneity.
