[Chlamydia trachomatis and Ureaplasma urealyticum infection in patients with tubal pregnancy].

OBJECTIVE

To explore the relationship between genital infections with chlamydia trachomatis (CT) and ureaplasma urealyticum (UU) and tubal pregnancy.

METHODS

34 patients with tubal pregnancy (case group), 28 women undergoing tubal ligation (control group A) and 40 women with normal early intrauterine pregnancy (control group B) were investigated as a case-control study. The polymerase chain reaction (PCR) technique was used to detect CT DNA and UU DNA in samples from the secretion of cervix, fallopian tube and pelvic fluid.

RESULTS

Case group was more likely to have detectable CT DNA (47.1%) and UU DNA (55.9%) from cervical secretion than control group A and B (P < 0.05). CT DNA detective rate from fallopian tube was significantly higher in case group than the control group A (26.5% versus 3.6%, P < 0.05). There were no significant differences in the positive rates of UU DNA from fallopian tube, CT DNA and UU DNA from pelvic fluid between case group and control group A.

CONCLUSION

There is a strong association between tubal pregnancy and genital infection with CT and UU.
