Chlamydial infection of the urogenital tract in promiscuous and non-promiscuous women.

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.
