Chlamydia trachomatis--cytologic findings in infections of the uterine cervix

Cytologic, colposcopic, histologic and bacteriologic examination was performed in 229 patients because of previous abnormal cervical cytology. Chlamydia trachomatis was found in a significantly greater proportion as well in 70 women with spontaneous recurrence to normal (17.1%) as in 85 women with dysplasia (17.6%). In comparison, chlamydial infection is found in 4.1% of cytologically normal women. In the 2 to 22 months follow-up Chlamydia trachomatis was seen in 19.6% of 92 women with recurrence to normal cytologic pattern, however, in 10.8% of 65 patients with persistence or progression (p less than 0.025, t-test).
