Clinical manifestations of genital infection due to Chlamydia trachomatis in women: differences related to serovar.

Author information

Department of Medicine, University of Washington, Seattle.


The relationship between the infecting Chlamydia trachomatis serovar and the clinical manifestations of genital tract infection was evaluated in a study of 155 women attending a sexually transmitted diseases clinic; 99 women had lower genital tract infection and 56 had Chlamydia-associated pelvic inflammatory disease (PID). In the group with lower genital tract infection, women with serovar F differed from those with serovars of class B or C in that they exhibited fewer signs of cervical infection, including easily induced bleeding (P = .04), edema of the zone of cervical ectopy (P = .06), and colposcopic evidence of mucopurulent endocervical discharge (P = .007). Serovar F also produced fewer infections with inclusion counts of > or = 1,000 and fewer rectal infections (P = .04). There was no apparent association of any specific serovar with PID. Thus, in this population, serovar F was associated with fewer objective clinical manifestations of mucopurulent endocervical discharge, and the distribution of chlamydial serovars found in PID reflected that found in lower genital tract infection.
