中文摘要：

目的调查和分析解脲脲原体（Uu）、人型支原体（Mh）在生殖道感染者和健康女性人群中的感染状况，探讨其致病性和致病条件。方法在同期采集生殖道感染者和健康女性生殖道分泌物。采用培养法和倍比稀释法进行Uu和Mh的定性培养和颜色变化单位（CCU）浓度检测。对2类人群的支原体感染状况进行分析。结果生殖道感染者支原体阳性率（84．1％），显著高于健康女性人群（55．8％）（χ^2=26．4571，P〈0．0001）；生殖道感染者以Uu和Mh的混合感染为主，健康女性以单纯Uu感染为主。2者比较差异有统计学意义（χ^2=57．2132，P〈0．0001）。支原体CCU浓度检测结果显示，妇科炎症人群支原体浓度显著高于健康女性人群（Uu：秩和检验Z=-4．3094．P〈0．0001；Mh：秩和检验Z=-2．8820。P=0．0040）。结论Mh的致病性强于Uu；Uu和Mh并存具有一定的协同致病作用。且在感染菌量较高时易致临床症状出现。因此。对女性生殖道感染者进行支原体定量或半定量检测和有针对性治疗具有重要意义。

英文摘要：

Objective To study the pathogenicity and pathogenic condition of ureaplasma urealyticum（Uu） and mycoplasma homonis（Mh） by mycoplasma infection status between the healthy women and women with genital tract inflammation. Methods To collect the genital tract secretion in the two groups and detect the infectious ratio and Color Change Unit （CCU） concentration. To study and analyze the mycoplasma infectious status between the two kinds of people by combining with questionnaire data. Results （ 1 ） The positive ratio was 84.1% in women with genital inflammation, higher than healthy women whose positive ratio was 55.8 % （χ^2= 26. 4571, P 〈 0. 0001）. （2） Mixed infection of Uu and Mh is popular in infected women, Healthy women are easier to be infected by Uu（ χ^2= 57.2132, P 〈 0. 0001）. （3）The result of CCU concentration showed the infected concentration in women with genital tract inflammation was higher than healthy women. Conelusion The pathogenicity of Mh is stronger than Uu. The two kinds of mycoplasma have cooperation pathogenic effect. It is easy to lead clinical symptom in the high infectious concentration. So it is meaningful to detect mycoplasma by quantization or half - quantization detection among the infected women and to treat them properly.
