The prevalence and clinical features of Chlamydia trachomatis infection were studied in men with nongonococcal urethritis (NGU), in their female sexual partners, and in other women. Of 92 patients with NGU, 36 (39%) were chlamydia-positive; although all had symptoms of urethritis, fewer than half had evident discharge. Clinical features of chlamydia-positive and chlamydia-negative NGU were indistinguishable. Most female contacts of chlamydia-positive patients with NGU were infected with C. trachomatis; contacts of chlamydia-negative patients with NGU seldom harboured chlamydia. Inflammatory and erosive changes were equally common in the uterine cervix of chlamydia-positive and chlamydia-negative women, although almost half of infected cases had no clinical signs of infection and no specific symptoms. In such women the present unavailability of sensitive screening techniques is a major obstacle to the effective control of chlamydial infection.
对患有非淋菌性尿道炎（NGU）的男性及其女性性伴侣以及其他女性的沙眼衣原体感染的患病率和临床特征进行了研究。在92例NGU患者中，36例（39%）衣原体呈阳性；尽管所有患者均有尿道炎症状，但只有不到一半的患者有明显分泌物。衣原体阳性和衣原体阴性的NGU的临床特征难以区分。衣原体阳性的NGU患者的大多数女性性伴侣感染了沙眼衣原体；衣原体阴性的NGU患者的性伴侣很少携带衣原体。衣原体阳性和衣原体阴性女性的子宫颈出现炎症和糜烂性变化的情况同样常见，尽管几乎一半的感染病例没有感染的临床体征和特定症状。对于这类女性，目前缺乏敏感的筛查技术是有效控制衣原体感染的主要障碍。
