阴道毛滴虫在性传播疾病患者寄生情况的研究

为了解阴道毛滴虫在淋病等性传播疾病（ＳＴＤ）患者寄生的情况，分析阴道毛滴虫寄生与ＳＴＤ之间可能存在的关系，对临床上拟诊的ＳＴＤ患者２２４５人和正常健康女工１９１人，分别采用生理盐水涂片法镜检阴道毛滴虫滋养体。结果显示ＳＴＤ组阴道毛滴虫滋养体的平均检出率为３０．９１％（６９４／２２４５），高于正常对照组检出率１．０５％（２／１９１），差异非常显著（Ｐ＜０．００１）。前者以淋病和支原体感染者阴道毛滴虫滋养体的检出率较高，分别为３０．５３％和３８．２２％。此外，ＳＴＤ组受检者中，性罪错妇女阴道毛滴虫滋养体的检出率高于一般病例，并且患淋病和支原体感染的性罪错妇女阴道毛滴虫滋养体的检出率更高，分别为３４．６２％和４３．３２％。沙眼衣原体感染者、梅毒和尖锐湿疣患者阴道毛滴虫滋养体的检出率也高于正常对照组。

STUDY ON PARASITIC CONDITION OF TRICHOMONAS VAGINALISIN SEXUALLY TRANSMITTED DISEASE PATIENTS

In order to understand parasitic conditions of Trichomonas vaginalis in patients with sexually transmitted disease(STD), we investigated trophozoites of T. vaginalis in 2 245 patients suspected of suffering from STD(including 1 098 prostitutional women) and 191 healthy female workers with the smear method of normal saline. The average detective rate in the STD group(30.91%) was obviously higher than that in the normal control group(1.05%). There was a significant difference in the statistics(2=53.41,P<0.001). In the former, the detective rate of trophozoites of T. vaginalis in patients with gonorrhea and Mycoplasma infection was higher. In examination of STD group, the detective rate of trophozoites of T. vaginalis in prostitutional women was higher than that in general clinic cases. Moreover the detective rate of trophozoites of T. vaginalis in prostitutional women of patients with gonorrhea and Mycoplasma infection was the highest. Therefore, conventional examination of T. vaginalis in STD patients
