Ninety-eight women attending three different clinics were prospectivel
y studied for the presence of genital tract infections, including Chla
mydia trachomatis. Of these 98 women, 35 were presenting to a polyclin
ic with symptoms of genital tract infection, 55 were attending an ante
natal clinic for their first visit, and 8 referred to a colposcopy cli
nic because of an abnormal Papanicolaou smear were included. Gonorrhoe
a was detected in one patient, syphilis in two, and Trichomonas vagina
lis in six. Candida albicans and Chlamydia trachomatis were each detec
ted in 18 patients, while the most common condition was bacterial vagi
nosis, detected in 35 patients. The prevalence of these infections was
lowest in patients referred for colposcopy and highest in the women a
ttending the antenatal clinic. Chlamydia trachomatis was the most comm
on sexually-transmitted pathogen detected in this population. These da
ta emphasise the need for an aggressive approach to the diagnosis and
treatment of chlamydial infection in females.
