Chlamydia trachomatis infection of the urogenital tract of women presumed to be non-promiscuous, and in presumably promiscuous women attending a Special Clinic in Manchester was studied. Two hundred female members of hospital staff, who formed the non-promiscuous group, were found to have a 1% incidence of chlamydial infection. This compared with an incidence of 26% among 200 women attending the clinic. Among the clinic patients, chlamydial infection was significantly linked with the presence of gonorrhoea, mixed infections, and other sexually transmissible diseases--such as, trichomoniasis. No correlation could be made be made between the incidence of chlamydial infection and the use of oral contraceptives.
对假定非滥交的女性泌尿生殖道沙眼衣原体感染情况，以及在曼彻斯特一家专科诊所就诊的推测为滥交的女性进行了研究。200名医院工作人员组成了非滥交组，发现衣原体感染率为1%。相比之下，在该诊所就诊的200名女性中，感染率为26%。在诊所患者中，衣原体感染与淋病、混合感染以及其他性传播疾病（如滴虫病）的存在显著相关。衣原体感染率与口服避孕药的使用之间没有相关性。
