Chlamydia trachomatis was recoved from 20% (36/180) of women attending a venereal disease clinic. All infected women had chlamydial antibodies in their serum and cervical secretions. However, the background rates of chlamydial antibody in chlamydia-negative women were very high. Measurement of antibodies in serum (complement fixation or immunoglobulin G [IgG] and IgM by microimmunofluorescence) or cervical secretion (IgG, IgM, IgA or secretory IgA classes) did not result in predictive values of greater than 32%. It is concluded that the detection of chlamydial antibodies in serum or cervical secretions cannot be substituted for agent isolation in diagnosing these infections.
从一家性病诊所就诊的女性中,20%(36/180)检出沙眼衣原体。所有感染女性的血清和宫颈分泌物中均有衣原体抗体。然而,衣原体阴性女性中衣原体抗体的背景率非常高。检测血清中的抗体(补体结合试验或用微量免疫荧光法检测免疫球蛋白G[IgG]和IgM)或宫颈分泌物中的抗体(IgG、IgM、IgA或分泌型IgA类别),预测值均未超过32%。结论是,在诊断这些感染时,血清或宫颈分泌物中衣原体抗体的检测不能替代病原体分离。
